No flush = No effect



"Inositol Hexanicotinate is the true 'flushless niacin.' Unlike 'sustained-release' niacin, which is just regular niacin in a pill which dissolves more slowly, Inositol Hexanicotinate is a niacin complex, formed with the B-vitamin-like inositol. When you take an IHN supplement, the central inositol ring gradually releases niacin molecules, one at a time delivering true niacin. This, like “sustained-release” niacin, allows you to take niacin at clinically-proven doses without going crazy with the itch."


That above bit of nonsense adorns one manufacturers sales pitch for its no-flush niacin. No-flush niacin is one of the biggest scams in the health food store.

Ordinarily, I love health food stores. There's lots of fun and interesting things available that pack real power for your health program. Unfortunately, there's also outright nonsense. No-flush niacin is absolute nonsennse.

No-flush niacin is inositol hexaniacinate, or an inositol molecule complexed with 6 niacin molecules. So it really does contain niacin. However, although it works in rats, it exerts no known effect in humans.

Just Friday, a 41-year old woman came to my office for consultation because her doctor didn't know what to do with lipoprotein(a). She had seen a cardiologist who told her to take no-flush niacin. Both the cardiologist and the patient were therefore puzzled when lipoprotein(a) showed no drop and, in fact, was slightly higher on the no-flush preparation.

The lack of any observable effect and no studies whatsoever showing a positive effect (there is one study demonstrating no effect), manufacturers continue to manufacture it and health food stores continue to push it as an alternative to niacin that causes the flush. It's quite expensive, commonly costing $30-$50 for 100 tablets.

Don't fall for this gimmick. Niacin is among the most helpful of treatments for gaining control over coronary plaque. It raises HDL, corrects small LDL, reduces triglycerides (along with its friend, fish oil, of course), reduces lipoprotein(a), and dramatically contributes to reduced heart attack risk. No-flush niacin does none of this.

"Black holes" on heart scan


Lots of smokers, especially younger smokers, rationalize their habit by telling themselves that they'll stop if and when any hint of adverse health effects develop.

The problem is that, even in the first decade of smoking, dramatic and profound effects can develop--but you won't know it.

One of the most graphic examples of this I see every day in people who have heart scans. While CT heart scans are, of course, for identification of coronary plaque/coronary disease, they're also great for visualizing the lungs.

This man is a light smoker. The lungs are the black tissues (that's normal) on either side of the (white) heart in the center. Now, note the holes in the lung tissue. That's what they literally are: holes left by the destrucive, tissue-eating effects of cigarette smoking.

How common are the holes (or emphysematous "blebs", as they're called in medical lingo)? Very common. You'll even see them in 30-somethings who've smoked only a few years.

These are holes that have nothing in them. The lung tissue that was destroyed to create the hole will never grow back, even when smoking stops. The holes in this example are actually small to average in size. I've seen much bigger. And this only represents the early stages of lung tissue destruction. A long-time heavy smoker shows all other sorts of abnormalities.

Whenever I show these "black holes" to people who smoke, they are horrified and I've actually gotten many people to quit. Take the opportunity to quit as soon as you can if you smoke.

Small LDL--a persistent bugger

Sometimes, small LDL is easy to get rid of. Take niacin, for instance, and it can simply disappear from your body.

But other times, it can be aggravatingly persistent. Several times every day, in fact, I need to run through the checklist of strategies to reduce small LDL with patients.

How important is small LDL? In my experience, it is among the most potent causes behind coronary plaque known. It's a big part of the explanation why some people at an LDL of cholesterol of X mg/dl will have heart disease, while others with the same X mg/dl of LDL will not. When present, small LDL particles are much more likely to trigger atherosclerotic plaque formation. Small LDL particles magnify Lp(a)'s ill-effects tremendously. The data vary but small LDL probably increases heart attack risk at least three-fold.



Here's a checklist of strategies that I advise patients to consider to minimize the small LDL pattern:


--Lose weight to ideal weight--This is very important and effective.


--Fish oil--A relatively small effect unless triglycerides are high to begin with.




--Reduction of wheat products--This can provide a BIG effect. More precisely, a reduction in high-glycemic index foods is effective. But the biggest day-to-day high-glycemic food culprits are wheat products like breads, pasta, crackers, chips, pretzels, and breakfast cereals. "You mean whole wheat bread makes small LDL?!" Yup.


--Reduction of sweets--For the same reasons as reducing wheat products.


--Add raw almonds and walnuts--1/4 to 1/2 cup per day.




--Replace wheat products with OAT products, especially oat bran. This does NOT mean oat-containing breakfast cereals with added sugar and wheat, e.g., Honey Nut Cheerios, Cracklin' Oat Bran Cereal, etc. You might as well eat candy. Buy oat bran as plain oat bran--nothing added. Use it as a hot cereal or added to yogurt, "breading" for chicken, etc.




--Vitamin D--A variable effect, likely resulting from its beneficial effects on "insulin resistance".


--Exercise


--Niacin--Very effective but not always enough.


Among the choices, my favorites are weight loss, niacin, and reduction of wheat products. Those will give you the biggest bang for your buck.

Red badge of courage

A group of 60- and 70-somethings were standing in the anteroom to the cardiac rehabilitation center. All (males) had their T-shirts pulled up, comparing their coronary bypass scars.

It reminds me of war veterans comparing their war wounds. The scars of suffering, of having "conquered" and won a war with a common enemy, a badge of courage.

This is part of the broad social acceptance of bypass surgery and other major procedures for heart disease. Hospitals support it. They do it for the psychological support for patients enduring a difficult process. Often, talking about a shared experience can be a helpful purge for the fears and frustrations of a traumatic event.

Curious thing, though. I've actually had people request bypass surgery simply because all their friends have had one. No kidding. "I just figure my time is coming. I might as well get it over with."

Get the picture? We've had a battle with heart disease and the hospitals have won. The enormous success of hospitals over the last 20 years is not because of delivering babies, it's not from psychiatric hospitalization, it's not from cancer treatment. It's from heart disease. The largest floors in the hospital are usually the cardiac floors. The bulk of revenues and profit are from heart disease.

If I manufacture widgets and each widget I sell makes me scads of money, guess what? I want to sell more and more widgets. I'll persuade people they need my widgets even if they don't. Perhaps I'll even persuade them that buying one is a noble cause. Maybe I'll subtly suggest that I am a charitable operation and I only sell my products for the public good. I could even name my company after a saint. Personal profit--absolutely not!

Ignore the hype. See hospitals and their "products" for what they are: A necessary service--some of the time; profitable products that they hope to sell to more and more people most of the time.

"We don't believe in heart scans"

Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.

More on the “Rule of 60”

Despite its apparent simplicity, there’s a lot of thought and wisdom in the Rule of 60.

What if you achieve only a single value in the Track Your Plaque “Rule of 60”? What if, for instance, you got LDL down to 60 mg/dl, but ignored the fact that your HDL was 41 mg/dl and triglycerides were up to 145 mg/dl? Can you still do pretty well?

Probably not. In fact, this specific combination of low HDL and high triglycerides tells me several things:

1) LDL is really much higher than suggested by the 60 mg/dl, which is a calculated value, often much higher. Recall that calculated LDL is prone to immense inaccuracy. When measured, the LDL is commonly somewhere between 120 and 160 mg/dl. However, when you raise HDL to 60 and reduce triglycerides to 60, much of the inaccuracy is removed, i.e., calculated LDL becomes more accurate. LDL can be measured as LDL particle number (NMR), apoprotein B, or direct LDL.

2) LDL particles are small. This is yet another reason why the weight-based LDL measures can be inaccurate. Imagine you have two identical glass jars full of marbles. One jar has small marbles, the other has large marbles, but both jars have the same weight in marbles. Which jar has more marbles? The one with small marbles, of course. The same phenomenon occurs with LDL particles: at the same weight, you can have different numbers of LDL particles. It’s the number of particles that better determine risk for heart disease, not the weight.

3) Triglycerides of 145 mg/dl is actually below the target advised by the National Cholesterol Education Panel Adult Treatment Panel-III guidelines, i.e., you’re okay by conventional standard. But look beneath the surface, and you’ll find that triglycerides at 145 mg/dl are associated with flagrant excesses of VLDL lipoprotein particles and a greater likelihood of a postprandial (after-eating) disorder (increased IDL or postprandial triglycerides), both of which add to coronary plaque.

4) This pattern is also commonly associated with higher blood sugar, higher blood pressure, increased inflammation (e.g., C-reactive protein), increased fibrinogen—all the facets of the metabolic syndrome, or pre-diabetes.

In fact, some of the most aggressive plaque growth—increasing heart scan scores—will occur with this specific pattern. So just achieving one facet of the Track Your Plaque Rule of 60 does not suffice. It’s the whole package that really stacks the odds in your favor of stopping or dropping your heart scan score.

The Track Your Plaque “Rule of 60”

The Track Your Plaque recommended targets for conventional lipids (i.e., LDL, HDL, triglycerides) are LDL 60 mg/dl, HDL 60 mg/dl, and triglycerides 60 mg/dl: 60-60-60.

Not only is this set of values easy to remember—60-60-60—but is grounded in science and the results of clinical trials.

LDL 60 mg/dl
The LDL target is based on experiences such as that of the Reversal Trial, the PROVE-IT Trial, and the Asteroid Trial, all of which showed that LDL cholesterol values in the range of 60 mg/dl dramatically enhance the likelihood of stopping plaque growth or achieving regression, reducing risk of heart attack more than more lenient LDL targets.


HDL 60 mg/dl
Achieving HDL cholesterol of 60 mg/dl is not as well grounded as LDL targets, mostly because increasing HDL is more difficult. There’s also no tremendously profitable way to raise HDL, as there is for reducing LDL (statin drugs). But epidemiologic observations strongly suggest that HDL of 60 mg/dl provides maximum control over both coronary plaque growth, as well as slashing rates of heart attack. Numerous smaller trials have borne this phenomenon out.


Triglycerides 60 mg/dl
Triglycerides of 60 mg/dl is based principally on studies that have shown a virtual elimination of abnormal lipoproteins, especially small LDL, when this value is achieved. Reduction of triglycerides is an effective means to reduce hidden lipoproteins like small LDL and VLDL. Triglycerides in the conventionally acceptable range of 100-150 mg/dl can be associated with dramatic abnormalities of lipoproteins.


Thus, the Track Your Plaque “Rule of 60”. In our day to day experience of trying to stamp out plaque growth from its terrifyingly rapid 30% per year, or reversing it—-dropping your heart scan score—-the Rule of 60 has held up time and again. Getting your lipids to 60 mg/dl does not guarantee that plaque growth stops, but it appears to be a necessary requirement that tips the scales heavily in your favor.

Those of you who’ve discussed lipid targets with your doctor will quickly recognize that the Track Your Plaque targets appear laughably ambitious, perhaps unnecessary. Recall that your doctor likely has no idea of what coronary plaque regression means. He/she likely conforms to the lax targets set by the National Cholesterol Education Panel (NCEP). (These targets depend on a number of factors such as whether you’re diabetic, sex, risk factors, etc.) Based on trial experiences like the few mentioned above, as well as my experience with purposeful coronary plaque reversal, the lipid guidelines as advocated by NCEP guarantee heart disease. Let me emphasize that again: Follow the guidelines set by the NCEP for your doctor to follow, and progression of heart disease is a virtual certainty. At best, it may slow growth of plaque and delay your heart attack or bypass surgery, but it will not stop it.

Now, that point made, let me make another: Just knowing about the targets and even becoming a member of the Track Your Plaque program does not mean that your lipids with automatically go to 60-60-60. We’ve actually had an occasional person tell us that they were disappointed that, by becoming Members, why hadn’t their lipids gone to 60-60-60?

Knowing that the 60-60-60 targets provide real advantage is not the same as actually achieving them.

A little bit of fish oil


The British National Health Service (NHS) has announced that, in light of the substantial data documenting that omega-3 fatty acid intake from fish reduces likelihood of cardiovascular events by around 40%, that Brits discharged from hospital following a heart attack should be "prescribed" 1000 mg of prescription fish oil per day.

Hardly a revolutionary concept. Part of the timidity of the British NHS seems to relate to the potential cost to the government, since apparently much of the cost will be borne by the government-subsidized health system.

But prescription fish oil? Why prescription fish oil? Prescription Omacor, one capsule per day, costs around $70 (U.S.) per month. If I go to Sam's Club the same quantity of omega-3 fatty acids (in three capsules) will cost around $2.50. That's less than 5% of the cost of the prescription form.

Omacor is clearly more concentrated. But is the prescription form better--more effective, more purified, less contaminated, etc.? I have seen no independent verification of this. Of course, manufacturers make all sorts of claims. The only independent, unbiased testing I'm aware of comes from organizations like Consumer Reports and www.consumerlabs.com. Omacor has not been compared to non-prescription fish oil in any of their analyses. Head-to-head comparison of Omacor to nutritional supplement fish oil is unlikely to come from Solvay, the manufacturer of Omacor. Drug companies powerfully resist head-to-head comparisons, fearing it will not play out in their favor. Let the public remain ignorant and hope marketing conquers all.

Why would the NHS only recommend eating fish and prescription fish oil? I don't know, but it smells awfully fishy to me. As soon as an opportunity for profit is built into a treatment, all of a sudden it gains endorsement. Perhaps lobbying by those parties with potential for profit drove the process.

Nonetheless, despite the filthy politics and under-the-table dealings, some good comes out of the NHS's action: broader recognition of the power of fish oil. Perhaps when a British patient or an American patient gets discharged with a prescription for Omacor, the patient will take the initiative and go to the health food store instead and save him (or his insurer) $67.50 per month.

For your coronary plaque control program and control and/or reversal of your heart scan score, we start at 4000 mg per day of standard fish oil, providing 1200 mg per day of omega-3 oils. This amount as a nutritional supplement costs only a few dollars a month. And you have the satisfaction of not only taking a powerful step for your health, but also not enriching the overflowing pockets of drug companies.

AHA: Doctors don't have time for prevention

Doctors "don't have enough time to educate their patients and to stop and think about what measures the patient really needs," says Dr. Raymond Gibbons, new head of the American Heart Association.

Dr. Gibbons highlighted how the system reimburses generously for performing procedures, but reimburses relatively little (often just a few dollars) for providing preventive counseling. He claims to have several ideas for solutions.

Good for Dr. Gibbons. There's no doubt that the lack of truly effective preventive information and counseling is a systemic, built-in flaw in the current medical environment. It is especially true in heart disease.

Another problem: "If a doctor didn't say it, it must not be true." That's the attitude of many of my colleagues. Despite their broad and systematic failure to provide preventive counseling, most physicians (my colleagues the cardiologists especially) pooh-pooh information that comes from other sources. Yet, it's my prediction that much of healthcare will go the way of optometry--direct access to care, often delivered in non-healthcare settings like a store or mall. People are hungry for truly self-empowering health information. Too many physicians can't or won't provide it. You've got to turn elsewhere for it.

That's one of the main reasons I set up the Track Your Plaque program. It's direct access to self-empowering information. A flaw: You still require the assistance of a physician to obtain lab values, lipoproteins, and to monitor certain treatments (e.g., niacin at higher doses). If I knew of a way around this, I'd tell you. But right now I don't. We remain constrained by legal and moral obligations.

Nonetheless, phenomena like CT heart scanning and the Track Your Plaque program are just a taste of things to come.

Confusion about Lp(a)

Since the recent reader question about Lp(a), I've had several other instances of confusion over Lp(a).

To help you navigate through some of the often confusing issues behind this complex genetic abnormality, here are some common sense rules to follow. When you ask your doctor to draw a Lp(a), try to be certain that:

--the same laboratory is always used. Just going from lab to lab can account for huge variation in Lp(a). As standardization proceeds internationally, this will be become less important. But in 2006, it's still an issue.

--you and your doctor resist the temptation to check Lp(a) frequently. I saw a patient recently who was having Lp(a) levels nearly every month. This is pointless. Lp(a) changes very slowly. Checking it frequently will not allow any treatment to be fully reflected. All you'll observe is random variation that can be frustrating. We wait at least 6 months before re-checking after a new treatment is introduced.

If you have a choice, I would recommend you opt for the measure provided by Liposcience (NMR). The technique they use is a particle count measure, rather than a weight-based measure. This may be more accurate, particularly when Lp(a) is small.

Lp(a) remains among the more difficult patterns to understand and correct. Don't be surprised if you encounter a lot of confusion from your doctor, as well. You may end up providing much of his/her education.
Fractures and vitamin D

Fractures and vitamin D

This is a bit off topic, but it's such an interesting observation that I'd like to pass it on.

Over the past several years, there have been inevitable bone fractures: People slip on ice, for instance, and fracture a wrist or elbow. Or miss a step and fracture a foot, fall off a ladder and fracture a leg.

People will come to my office and tell me that their orthopedist commented that they healed faster than usual, often faster than anyone else they've seen before. My son was told this after he shattered his hand getting slammed against the boards in hockey; his orthopedist took the screws and cast off much sooner than usual since he judged that healing had occured early. (My son was taking 8000 units vitamin D in gelcap form; I also had him take 20,000 units for several days early after his injury to be absolutely sure he had sufficient levels.)

My suspicion is that people taking vitamin D sufficient to enjoy desirable blood levels (I aim for a 25-hydroxy vitamin D level of 60-70 ng/ml) heal fractures much faster, abbreviating healing time (crudely estimated) by at least 30%.

For any interested orthopedist, it would be an easy clinical study: Enroll people with traumatic fractures, randomize to vitamin D at, say, 10,000 units per day vs. placebo, watch who heals faster gauged by, for instance, x-ray. My prediction: Vitamin D will win hands down with faster healing and perhaps more assured fusion of the fracture site.

    Just anecdotal, but I had an experience that confirms your theory.  In the middle of a 21-day trip down the Colorado through Grand Canyon, I fell and fractured my arm.  I decided just to splint it up and continue the trip, since the pain wasn't too bad.

    By the time I got to a clinic in Flagstaff, 10 days later, the doctor said everything had healed so well I didn't even need a cast.  

    Needless to say, there is lots of free Vitamin D in the Grand Canyon in summer!  We were in the sun all day long.  Maybe it made the difference.

    Last fall I was happy with my blood level of vit D, 79 ng/ml, so I reduced my daily dose from 10,000 iu to 5,000 iu.   I just got my spring test result and my level dropped 23 points to 56 ng/ml.  I'm gonna go back to 10,000 iu, except maybe during the summer when I get a lot of sun.

    How to Optimize Vitamin D Supplementation to Prevent Cancer, Based on Cellular Adaptation and Hydroxylase Enzymology" You can read Reinhold Vieth's justification for keeping 25(OH)D both high and STABLE here.
    In order to regulate any system there has to be a means of both increasing and decreasing responses.
    Where the upregulation and down regulation is performed by different substances both of which are derived from Vitamin D, it follows these have to be kept tightly controlled and always in balance.
    Sudden rise in 25(OH)D causes a period of imbalance between those forces, during which too much immunosuppression may occur.
    The further north people live the more extreme differences between Summer/winter status. It isn't surprising those flying to the tropics for short midwinter sun breaks end up catching something from recycled germs during the flight home.
    Making sure your Vitamin D needs are met daily throughout the year evens out the percentage change in levels as naturally more vitamin D3 is made in low 25(OH)D skin than when 25(OH)D is high.

    Correcting vitamin D deficiency BEFORE a winter sun break results in a lower increase in 25(OH)D.
    Less change in status = shorter period of imbalance.

    I don't have to remind readers here Ergocalciferol speeds up the catabolism of vitamin D Cholecalciferol has a longer half life. Using Vitamin D2 therefore promotes greater/faster swings in status and should be avoided.

    Using Vitamin D3 supplements daily at amounts no greater than UVB exposed skin would naturally produce, most nearly replicates the changes in status human DNA would have evolved with.

    Apologies to Dr Vieth for assuming the copy of the paper linked to above was non-copyright and putting it online.  I think it's important the public have access to the full text rather than just my garbled version of this important paper.

    Thanks Dr. Davis for the post sharing you personal experiences.

    DrStrange:

    The relationship seems to follow a U-curve pattern, with very high levels being associated with hypervitaminosis D problems.

    The levels mentioned by Dr. Davis seem well below the ones that can lead to toxicity. For example, a farmer in Puerto Rico had a level of 225 nmol/L (90 ng/mL), and had no signs of toxicity:

    http://healthcorrelator.blogspot.com/2010/02/vitamin-d-levels-sunlight-age-and.html

    From the post above, toxic doses seem to start around 50,000 IU per day. That's way more than the 10,000 IU or so that we get from sun exposure.

    My only point of disagreement with Dr. Davis is about our ability to produce vitamin D from sunlight after age 40. There is research (post above too) showing that the elderly can produce as much as 80 percent vitamin D from sunlight as do 20 or 30 year olds.

    I hope I'm not diverting from the topic here....I'm confused about the Vit D-Calcium interaction.

    I believe I understand correctly that high Vit D levels allow the body to more effectively process calcium.

    I don't understand how calcium requirements change with increased Vit D levels.  I have a blood level of 72 (D3) and 3 (D2).  But I haven't paid attention to my calcium intake.

    Can anyone clarify the relationship between Vid D and calcium please?

    Thank you in advance.

    "The relationship seems to follow a U-curve pattern, with very high levels being associated with hypervitaminosis D problems."

    Not hypervitaminosis D but rather reversal of D's benefits.  I had read that above 60 ng/ml the risk of prostate cancer increased again.  Just now searching for the study found on D council site, a recent article showing the likelihood that this outcome was because the research subjects had all gotten their higher D levels from Cod liver oil and the vitiman A in that is what reversed the benefits of D, not the high levels of D!  So seems I could well have been misinformed about that.

    @ Dr Strange
    Tuohimaa's team claiming they have found a U shaped curve for Vitamin D is based in Tampere, Finland latitude 61N
    People at that latitude with high 25(OH)D levels have experienced a greater change in level from summer to winter or if they choose to take a winter sun break will experience further re-balancing of the immune system. Vieth argues it is the length and number of periods of imbalance that drive the effects Tuohimaa reports.

    Now we have greater availability of effective strength D3 it will be easier for people at that latitude to attain and maintain the levels that enabled the Inuit to survive long winters with over 6000iu daily vitamin D3 provided from traditional diet.

    @ Tom
    Video of Heaney explaining the calcium/vitamin D story

    The Vitamin D requirement in health and disease Heaney similar information in PDF form but in greater detail.
    Bear in mind when considering Vitamin D and Calcium absorption that other co-factors work in synergy with Vitamin D.
    Magnesium is required to power the  production of the active hormone Calcitriol that lowers PTH and magnesium also counterbalances the role of calcium as magnesium is a natural calcium channel blocker.
    Each Vitamin D Receptor requires zinc.
    Also Vitamin K2 mk4 is critical for healthy bone density transporting calcium from bloodstream to bone.

    This is another area where common sence and experience shouldn't really require a study to initiate this course of action.

    To TED,

    Thank you Ted for the information.  The Heaney video was very interesting and worthwhile.  It's interesting that he says optimal D3 for calcium absorbtion is between 80 and 120 nmol.  I'm at 70 nmol and thought I was fine!
    The video is well worth watching.

    nevertheless, I'm still trying to understand how much calcium I should be taking, assuming I get my D3 to 80 or so.

    Your remarks about Magnesium, etc. are helpful.  Thank you.  But again, I struggle with how much?

    Ted,
    Another explanation, this one from Cannell, for the U curve found in Scandinavia is cod liver oil.  

    People with the highest vit D levels may be consuming enormous amounts of cod liver oil and, thus, vitamin A.

    Excess retinol may thwart the action of vit D by competing for certain nuclear receptors.

    Do you know if anything helps for soft tissue injuries? I am still not fully recovered from a foot injury 5 months after the acute phase. The orthopedist expected it to take 4 weeks to heal and I'm a little concerned about how long it will take.

    The above blog post is quite informative. Having good information related to bones and its requirements. I was not knowing that Vit D is so important for our bones. But good to know about that. Want to ask what are the natural resources of Vit D in our daily diet?

    Quite an informative blog post. I know that inadequate amount of vitamin D in diet can lead to osteoporosis, which is a brittle bone disease. But are there any side effects of excessive intake of vitamin D.

    I know someone who was in a car accident that resulted in very serious fractures of one arm and wrist.  He is in his late 60's and his injuries were not healing.  

    I came to know this person about 6 months after the accident.   He was taking about 2 grams of  calcium per day thinking that this would help his bones, perhaps because the doctor told him to talk more calcium, but no supplemental  Vitamin D.   I told him that the should be taking at least 5000UI D3  per day pointing out that Walmart has 5000UI gel caps for cheap ($5 per 100 at that time) and that he was likely taking too much calcium.  He started taking more D3 although I am not sure how much since I didn't want to be pushy.  

    It has been about 9 months now since he started taking more D3 and his injuries have healed and he has had surgery to remove most of the plates and screws that had been put in place.    Was D3 the reason for this?    I don't know but I am sure that it didn't hurt either.
