Vitamin D deficiency is rampant

12. May 2006 William Davis (0)
Today alone I've seen several people with severe deficiencies of vitamin D.

We're now checking everyone's blood vitamin D level at the start of the program. The measure that most accurately reflects your vitamin D status is 25-OH-vitamin D3. This is very confusing to many physicians, who traditionally have thought of 1,25-di-Hydroxy vitamin D3 as the standard test to measure. What they're failing to recognize is that this second measure is a kidney product, not a reflection of vitamin D status.

Using 25-OH-vitamin D3, several people today alone had levels of <10 ng/ml, clearly in the category of severe deficiency (generally regarded as <20ng/ml).

The majority of people we see in the office are Wisconsin residents. It's no wonder they're deficient. Although it's mid-May, we've seen the sun only a handful of days this year. And most of the days have been too chilly to wear short sleeves and shorts to permit sufficient surface area for UV exposure.

Living in a sunny climate, however, is no guarantee that you have sufficient blood vitamin D levels. Two recent studies have shown that 30-50% of the residents of sunny southern Florida and Hawaii are also deficient. (Why, I'm not sure.)

Although our experience thus far is anecdotal in several hundred people, my impression is that people who have normal blood levels of vitamin D (we regard normal as 45-50 ng/ml) have a far easier time of halting or regressing coronary plaque.

Vitamin D is among the most exciting nutritional tools we've come across in a long time. The conversation is making the media, which impresses me tremendously, given the fact that nobody stands to profit financially to any significant degree through vitamin D supplementation.

For a wonderful collection of discussions on vitamin D, go to Dr. John Cannell's website, www.vitaminDcouncil.com. You'll find a huge quantity of scientific background and conversation on the whole idea. I believe you will be thoroughly impressed with just how powerful the argument in favor of vitamin D has become.

What if wheat products were illegal?

11. May 2006 William Davis (3)
Imagine if anything made of wheat were illegal: bread, bagels, crackers, pasta, pretzels, donuts, Shredded Wheat cereal, Raisin Bran, pastry, cookies, cakes, cupcakes. . . Your grocery store would then be unable to carry any of these products.

How empty would the grocery store shelves be?

There would be very little. The stores would be filled instead with vegetables and fruits, meats, and dairy products. But aisle after aisle would be empty. There'd be no cereal aisle. There'd be no snack chip aisle. The ordinarily overcrowded bread shelves wouldn't be there.

Bakery? Nope, not there either. Pasta and noodles? Empty. How about cakes and pastries? Also gone.

Getting the picture? American groceries are dominated by wheat products. What would happen to your health and the health of your family if wheat were abruptly removed from your choices? Would you be less healthy?

No. In fact, your health would be hugely improved. You'd lose a significant quantity of weight. Extraordinary numbers of people would lose diabetic or pre-diabetic tendencies. Feelings of sluggishness, sleepiness, and moodiness would dissolve. Blood pressure would be reduced. The incidence of cancer, skin disease, and inflammatory diseases would plumet.

From a plaque control perspective, your HDL cholesterol would rise, triglycerides drop. Small LDL would improve dramatically.

The message: Slash wheat products from your diet. Yes, you'll miss the smell and taste of freshly baked bread. But you'll do it for many more healthy years. And you may do it without a 14 inch scar in your chest.

The sobering tale of small LDL

10. May 2006 William Davis (0)
Every day, I learn to respect small LDL more and more.

Small LDL particles, and its evil partner, low HDL, is among the most common reasons why someone fails to fully gain control of coronary plaque and heart disease risk.

Just yesterday, I saw a slender businessman (6 feet 1 inch in height, 186 lb.) whose small pattern persisted despite niacin, fish oil, oat bran, and raw almonds. We generally think of small LDL as an overweight person's pattern, but in some people the genetics are quite powerful and it can be expressed even in slender people.

The solution: More physical activity and exercise; cut back on processed carbohydrates, particularly wheat products like breads, pasta, crackers, breakfast cereals; think about magnesium (see our two recent reports on magnesium on the www.cureality.com membership website, the latest report to be posted this week); be sure sleep is adequate (gauge this by whether you're energetic during the day and don't fall asleep watching TV or movies). Lack of sufficient physical activity in people with sedentary jobs is probably among the most common reason the small LDL pattern persists.

Ignore small LDL and it can be like a hidden cancer in your body, growing and metastasizing (not literally, of course), fueling coronary plaque growth. Be sure your doctor assesses whether you have small LDL if you hope to gain control of your coronary risk.

Burn off the fat

9. May 2006 William Davis (0)

If you've ever wondered just how many calories you're burning with various activities like yard work, driving, climbing stairs, etc. go to this great website that will calculate it for you: http://www.caloriecontrol.org/exercalc.html.

Here are some examples:


Dancing for 30 minutes(fast, e.g., tango): 193 calories
Yoga for 30 minutes: 204 calories
Washing the car for 30 minutes: 173 calories
Vacuuming for 30 minutes: 88 calories

(All are for a 170 lb person.)

As you see, physical activity does not necessarily have to consist of exercise. It doesn't require fancy equipment or expensive outfits. But it does require you to keep moving. Sedentary work is among the most common reasons I see in my patients for failing to control weight and its associated lipoprotein patterns, like low HDL and small LDL.

If your work is sedentary, then a minimum of 60 minutes of physical activity per day is necessary to begin to correct weight-related patterns. If you gauge by calories burned, then a useful goal is 500 calories per day in physical activity--at a minimum.

Go the distance!

8. May 2006 William Davis (0)
How long should it take to stop or reverse coronary plaque growth? How long will it require to stop your heart scan score of, say, 350, from increasing at the expected rate of 30% per year, slow it down (we say "decelerate") to less than 30%, or stop it altogether? Or, actually reduce your score?

It can vary widely. Several simple patterns do seem to emerge, however. Our experience is that lower scores, particularly less than 100 at the start, are easier to gain control over. Scores of 50 or less, in fact, commonly can return to zero.

Higher scores, particularly those >1000, are more difficult to slow or reduce, though we've done it many times. You'll generally have to try harder and it may take longer. It's not uncommon to not stop plaque growth with a starting score this high until your 2nd or 3rd year of effort.

Sometimes it may take even longer. An occasional person requires four or five years to gain control. And there are, unfortunately, some people who never really gain complete control. They slow plaque growth compared to what it would have been with conventional efforts, but never completely halt growth. Why? Sometimes it's a matter of less than full commitment. Other times, we just don't know. Thankfully, these especially difficult cases are few and the majority enjoy substantial slowing or reversal.

Since, in some people, success may take time, you've got to stick it out. Have you ever gotten lost in a strange city only to find out later that the place you were looking for was right around the corner? It can be the same way with stopping coronary plaque growth. If you start with a score of 1000 and, after two years of effort, you've only slowed growth to 11% per year and then give up in frustration, you may have missed the opportunity to have stopped growth entirely in your third year.

All we can do is tip the scales heavily in your favor. We provide you with the best tools known. You've got to provide the commitment, the consistent effort of taking your supplements or medication, making the lifestyle changes, choosing the right foods and avoiding the wrong ones. But you've got to go the distance and not give up too easily.

What you need is an expert in health!

5. May 2006 William Davis (0)
Where can you find an expert in health?

In my experience, they're hard--very hard--to find.

Your hospital? Certainly not the hospitals I know. The hospitals I know are experts in disease, but not in health. Hospitals are helpful when you're sick. But if you're well and would like to stay that way, there's no reason to hang around a hospital. Prevent cancer, prevent heart disease, stay well? There's no place for this conversation in a hospital.

In fact, hospital staff are among the most unhealthy people I come across. Obesity is a nationwide problem affecting millions of Americans. But it's especially a problem among people who work in hospitals. I shudder in horror when I go to a hospital cafeteria and witness the sorts of food they serve in hospitals and see what the staff eat. Should they be regarded as experts in health?

How about doctors? If you associate with physicians like the ones I know, most have lots of knowledge about disease, but little understanding of health. A rare one has insight and interest in health.

I went to a recent meeting with my cardiology colleagues. Food served: pizza, Coca-Cola, spaghetti, fried onion rings, white bread with butter. They all dug in without hesitation. Over half were miserably overweight. Several were, in fact, diabetic; several more, pre-diabetic. I know that at least several are smokers. Experts in health?

Drug companies? Well, they're interested in health only as far as it provides profits. But health for its own sake? Ask anybody from a drug manufacturer about their views on the nutritional supplement movement and watch them sneer.

Food manufacturers? You mean like Coca-Cola, Pepsi-Cola, Nabisco, and General Mills? How about fast-food operations like McDonald's, Pizza Hut, and KFC?

The message: Know where to look for genuine information on health. You won't get it from hospitals. You won't get it from drug company marketing. For the most part, you can't even get it from your physician.

Instead, you're going to witness a broad movement towards self-empowerment in health, fueled by the internet and services like ours (Track Your Plaque). These are information resources that are not driven by profit, intent on providing truth, and not afraid to reject prevailing views.

It does not mean that hospitals are unnecessary, or that food manufacturers are evil, or that fast food should be legislated out of existence. We live in a capitalistic society, driven by supply and demand. Hopefully, demand is borne from educated choices from informed consumers. That's where information that's reliable, credible, and not profit driven come in.

Lipoprotein(a) and small LDL

4. May 2006 William Davis (1)
It's been my suspicion for some time that the combination of lipoprotein(a), or Lp(a), in combination with small LDL particles is a really bad risk for heart disease. People with this combination seem to have much higher heart scan scores for age than others. This seems to be a pattern that we'll see in the occasional woman less than 50 years old who already has a high heaert scan score. (It's unusual for women to have detectable coronary plaque before age 50.)

Very little data exists to support this idea and we are in the process of performing a small study to see whether it's true or not. My gut sense: it's among the most potent causes of coronary plaque around.

Case in point: Even though I spend a great deal of my time and energy advocating heart disease prevention, I still maintain my hospital privileges and skills. I had to cover one of the emergency rooms in town this past weekend (a requirement to maintain my hospital privileges).

One of the patients I saw was a 40-year old man--we'll call him Roland-- suffering a very large heart attack, a so-called "anterior myocardial infarction", or a heart attack involving the most important front portion of the heart. Thankfully, he came to the ER within 45 minutes after his chest pain started. The situation was immediately obvious and I was called to the ER. We quickly took him to the cardiac catheterization laboratory and put a stent in the left anterior descending artery and flow was restored. His chest pain dissipated over the next few minutes.

Nonetheless, Roland was left with a large area of reduced contraction of his heart muscle. Only time will tell how much recovery he'll have.

Roland was extremely lucky. The majority of people with closure of the artery that he'd experienced die within minutes. He did, in fact, "arrest" briefly, i.e., his heart became electrically unstable, though he recovered promptly.

Along with the multiple tubes of blood we required to run tests for his heart attack management, we had Roland's lipids and other measures sent off, as well. Wouldn't you know: Lp(a) and small LDL. This may have accounted for a heart attack at age 40.

Keep a lookout for this when you have lipoprotein testing. Conveniently, niacin can be used to treat both patterns, though higher doses are generally required for the Lp(a) part of the pattern. It's also my belief that the sort of Lp(a) measurement performed by the Liposcience laboratory (www.liposcience.com) is superior. They use a particle number based measure, not a weight-based measure. It is therefore independent of particle size, which can vary. Further work will, I believe, reveal some very important insights into the dreaded Lp(a).

"Please don't tell my doctor I had a heart scan!"

30. April 2006 William Davis (1)
I overheard this recent conversation between a CT technologist and a 53-year old woman (who I'll call Joan) who just had a scan at a heart scan center:


CT Tech: It appears to me that you have a moderate quantity of coronary plaque. But you should know that this is a lot of plaque for a woman in your age group. A cardiologist will review your scan after it's been put through a software program that allows us to score your images.

Joan: (Sighing) I guess now I know. I've always suspected that I would have some plaque because of my mother. I just don't want to go through what she had to.

CT Tech: Then it's really important that you discuss these results with your doctor. If you wrote your doctor's name on the information sheet, we'll send him the results.

Joan: Oh, no! Don't send my doctor the results! I already asked him if I should get a scan and he said there was no reason to. He said he already knew that my cholesterol was kind of high and that was everything he needed to know. He actually got kind of irritated when I asked. So I think it's best that he doesn't get involved.


This is a conversation that I've overheard many times. (I'm not intentionally an eavesdropper; the physician reading station at the scan center where I interpret scans--Milwaukee Heart Scan--is situated so that I easily overhear conversations between the technologists and patients as they review images immediately after undergoing a scan.)

If Joan feels uncomfortable discussing her heart scan results with her doctor, where can she turn? Get another opinion? Rely on family and friends? Keep it a secret? Read up about heart disease on the internet? Ignore her heart scan?

I've seen people do all of these things. Ideally, people like Joan would simply tell their doctor about their scan and review the results. He/she would then 1) Discuss the implications of the scan, 2) Identify all concealed causes of plaque, and then 3) Help construct an effective program to gain control of plaque to halt or reverse its growth. Well, in my experience, fat chance. 98% of the time it won't happen.

I think it will happen in 10-20 years as public dissatisfaction with the limited answers provided through conventional routes grows and compels physicians to sit up and take notice that people are dying around them every day because of ignorance, misinformation, and greed.

But in 2006, if you're in a situation like Joan--your doctor is giving you lame answers to your questions or dismissing your concerns as neurotic--then PLEASE, PLEASE, PLEASE take advantage of the universe of tools in the Track Your Plaque program.

People tell me sometimes that our program is not that easy--it requires reading, thinking, follow-through, and often asking (persuading?) your doctor that some extra steps (like blood work) need to be performed. The alternative? Take Lipitor and keep your mouth shut? Just accept your fate, grin and bear it, hoping luck will hold out? To me, there's no rational choice here.

Doctor, why do I have heart disease?

30. April 2006 William Davis (0)
I see a great many people in my practice who come for a 2nd opinion regarding their coronary disease.

When I ask patients whether they ever asked their primary doctor or cardiologist why they have heart disease in the first place, I get one of several responses:

1) My doctor said it from high cholesterol.

2) My doctor said it was "genetic" or "part of your family history" and so unidentifiable and uncorrectable. Tough luck.

3) I didn't ask and they didn't tell me.


Let's talk about each of these.

Can heart disease be only from high cholesterol and, if so, can taking a statin cholesterol drug be a "cure"? In the vast majority of cases, in my experience, cholesterol by itself is rarely the only identifiable cause of coronary disease.

Most people have a multitude of causes (e.g., small LDL, low HDL, vitamin D deficiency, concealed pre-diabetic patterns, etc.). This explains why many people with high LDL don't have heart disease and why others with low HDL do have heart disease. High LDL cholesterol is only part of the cause.

Does "genetic" or being part of your family's history also mean unidentifiable and uncorrectable? Absolutely not.

What your doctor is really saying is "I don't know enough to diagnose the causes because I haven't kept up with the scientific literature", or "I don't want to be bothered with this because it takes a lot of time and pays me very little money; I'd rather wait until you need a stent ", or "The drug representatives haven't told me about any new drugs". This is ignorance and laziness at best, greed and profiteering at worst. Don't fall for it. I hope that by now you recognize that the great majority of causes of heart disease are identifiable and correctable.

If you didn't think to ask, now you know that you should. If you and your doctor don't think about why you have coronary plaque in the first place, how can you develop a program to control it?

You need to ask. And you need to get confident answers. "I don't know" or "It's genetic" and the like are unacceptable.

Pill pushers

28. April 2006 William Davis (1)
Have you read the latest cover story from Forbes magazine? It's entitled "Pill Pushers: How the drug industry abandoned science for salesmanship".

It's great reading. (A condensed version is available at the www.forbes.com website: http://www.forbes.com/business/forbes/2006/0508/094a.html. They require you to provide your e-mail address though it's free.)

Drug industry advertising has raised consciousness of all the prescription therapies available for us--that's good. However, they've gone so far overboard trying to squeeze more and more revenues out of drugs that they've cost this country a huge amount in increased health care costs and even lost lives. (Forbes does a great job of summarizing some of these instances.)

Drugs like Lipitor, Crestor, Zocor; diabetes agents; anti-hypertensive agents, etc., that is, medications taken chronically, a huge financial bonanzas for drug companies. Not only do they get $100-200 per month, but they get it month after month after month. That's per drug.

Now not all medications are bad or unnecessary. There are times when they can be truly necessary and beneficial. But don't rely on drug company advertising to tell us when.
What vitamin D form?

What vitamin D form?

15. February 2009 William Davis (36)
In response to questions regarding why don't vitamin D tablets work, here are my observations.

When I first started correcting vitamin D levels around 3 1/2 years ago, people would begin with starting 25-hydroxy vitamin D blood levels of around 20 ng/ml.

Taking, say, 6000 units vitamin D as tablets over 3 months yielded blood levels of 24-30 ng/ml. Taking 6000 units in an oil-based form, and blood levels would commonly be 60-70 ng/ml.

In other words, tablets are very poorly absorbed. I also saw very erratic absorption with tablets, with tremendous variation in blood levels.

I witnessed this effect many times. I finally began telling patients to avoid the tablets altogether. It's simply not worth it. Taking dose X of tablets, you cannot predict what the blood level of vitamin D will be.

Now, you can sometimes make the tablets get absorbed by either taking with a teaspoon of oil (e.g., olive, flaxseed) or taking with an oil-rich meal. However, I am uncertain just how consistent the absorption is under these circumstances, not having done this enough times to know.

Oil-filled gelcaps are no more expensive than tablets (or perhaps a dollar more). Health food store employees and pharmacists don't know this. I have had many patients come to the office claiming they changed to tablets because that's all their health food store or pharmacy carried and the person behind the counter assured them it was the same. Blood level of vitamin D to confirm: right back down to the starting level or near it--little or no absorption.

The only way to know whether a preparation is absorbed is to check a blood level. But, in my experience, having checked vitamin D blood levels thousands of times, gelcaps never fail; tablets fail over 80% of the time.

    Some of the vitamin D experts warn against using cod liver oil. http://www.vitamindcouncil.org/newsletter/2008-december.shtml

    One concern is too much vitamin A if you took enough of the cod liver oil to get the D you need. Another is that vitamin A and D compete with each other.

    Diana,

    Our family likes Carlson Vit D products.  They are definitely absorbable, because the whole family went from the low end fo the reference range to around 70-86 ng/ml in the past few months).

    Mostly we use Solar D Gems in the 2000 or 4000iU capsules.  There is a bit of Norwegian CLO & EPA?DHA in them, and lemon flavor.  They chew up easily, too, but can also be swallowed.

    The non-chewable capsules are much tinier and are made with sunflower oil, but even that is a very tiny amount in this very small capsule.

    The Carlson D drops in the 2000iU/drop dose is made with coconut oil (though it is fractionated, to keep it liquid).  But it's only a drop.

    I find very good prices at www.vitaminshoppe,com, usually for about 2-4 ¢ per each 1000iU (that's how I make price comparisons).  Plus Vitamin Shoppe has a frequent buyer program so purchases earn points toward fairly generous coupons (such as $5 off a $15+ purchase), and shipping is reasonable (sometimes free).  

    Or I buy Carlson Vit D3 at the local store when they are on sale (stores that sell a lot of Carlson product often pass along "mfg discounts" or "special buys").

    I believe the NOW foods brand D3 formulations are suspended in olive oil.

    Carlson's Vitamin D3, 2,000 IU is suspended in sunflower oil.

    That being said, most of these D3 capsules are quite tiny, so I am not sure that they contain a huge amount of oil, unless you are taking more than 10,000 IU's daily (i.e., 5 capsules).

    As to sources, iHerb is the best and most user friendly, and I won't even give you my $5. discount code, as previous poster did.  You can sign up for your own discount number at the iHerb website.

    total Vitamin A is below 2% of the daily value which is the threshold above which the FDA requires you to list the Vitamin A content.
    As adult RDA for vitamin A is 700~900iu, below 2% of that is below 14~18iu. So there is really is no reason to avoid Solar Gems because of their potential Vitamin A content.

Research now indicates that heart disease is the No. 1 cause of death among women in the US, while confirming that women with an intact uterus have a lower incidence of heart disease because they benefit from the uterine advantage."

    Dr. Davis,
    Are gelcaps with dried powdered form of vitamin d3 as effective as oil filled gelcaps?

    I've had great results from powdered gelcap from D-Max (5000 IU) from Nature's health Supply, but a bit less from NOW olive oil gelcaps (5000 IU). Just a hunch, because I have an autoimmune disease and I'm trying to work out my symptoms. So no 25(OH)D test here.

    I'll try those Carlson's next.

    Great blog by the way!

    I just ordered some D3 to send to my 81 yo MIL and 46 yo SIL in London.  I'm quite sure they are going to very deficient (they just ordered the www.grassrootshealth.net home testing kit as it's a pain to get NHS to agree to test).  

    I found Bio-Tech D3-5 (5000iU cholecalciferol capsules  - powder in a tiny gelatin capsule) offered on Drs. Eades's Protein Power website at a great price, 100 qty for $8.  Shipping via UPS was $6.45 to my location for up to 10 bottles.  That makes the price per 1000iu incredibly low.  I bought a year's supply (8 bottles) to mail to my in-laws, plus two bottles for me.  Note I was very surprised at the small size of the box, but it did contain the 10 bottles I ordered, but the capsules and bottles are small and light, which is nice when ordering so much at once and mailing it again.  Fast delivery, even with UPS ground service.

    I just had another 25 (OH)D test drawn last week; I'll get the results tomorrow at my endo appt for my thyroid.  I was averaging 5000iU/day  supplementation with various Carlson D3 products, based on previous 25 (OH)D test results and supplementation levels.  So I'll switch to the Eades' Bio-Tech formula now and see how my 25 (OH)D is in late summer/early fall.

    Anna,

    I'd be very interested to hear a follow up from you when you retest after being on the Bio-Tech D3 for awhile. I'm of the mind that D3 in softgel form is more absorbable and hence more efficacious for raising and maintaining 25(OH)D levels, but I see many of the "big guns" (e.g. Cannell, Eades, etc.)promoting/selling the powdered Bio-Tech formula. Perhaps you could report back here with your results?

    Dave,
    Sure.  I'll be retesting  thru my endo in 6 mo.  But I might do a mail-in test via www.grassrootshealth.net before that.  

    I'm guessing a gelatin capsule filled with a powder (might be an oily powder,too) is more absorbable than a hard tablet form.

    Btw, I just got my lab result for 25(oh)d---a nice 68ng/mL (after months of 5000iU D3 carlson oil gelcaps and/or oil drops .  Also was an easier winter than i've had in years, which I think might be due to more sunlight and Vit D.

    Thanks, Anna. 68 ng/ml-- Good for you! You know, all my life, I've had tough winters. I would always get very sluggish and depressed. I mean I would get really, really down. But ever since I've started the vitamin D, the winter blues are a thing of the past. This alone is probably the most noticeable effect I've ever had from taking any supplement. It's a very dramatic and welcomed change.

    That means D3 in Calcium tablets like Citrical is probably poorly absorbed  too, am I correct?

    Yep.

    Oil-filled gelcaps are no more expensive than tablets (or perhaps a dollar more). Health food store employees and pharmacists don't know this. I have had many patients come to the office claiming they changed to tablets because that's all their health food store or pharmacy carried and the person behind the counter assured them it was the same. Blood level of vitamin D to confirm: right back down to the starting level or near it--little or no absorption.
