D2 and D3 are two different things 3. September 2009 William Davis (15) Helena posted this instructive comment in response to the Heart Scan Blog post, Weight loss and vitamin D. It illustrates the confusion common among physicians and pharmacists on the differences between D2 and D3. (Edited slightly for clarity.)Not many weeks ago a colleague of mine (let’s call him Eric) asked me if I knew the difference between D2 and D3 and I told Eric that D2 comes from irradiated mushrooms and D3 comes from wool. In other words, D3 is the same kind of vitamin as humans get from the sun. Humans just don’t get enough and we can’t produce it on our own, like the sheep can. (D3 is natural for humans, D2 is not.)After telling Eric this, he asked me how he would know what he is taking and I gave him the medical definitions of them both (D2 = Ergocalciferol; D3 = Cholecaliciferol). Since I was aware that he had gotten his Vitamin D by prescription, I told him “I am 99.9% sure that you are taking D2, but I would be thrilled to find out I am wrong.” Eric called his pharmacy right away and got the answer I was expecting: ergocalciferol. On confronting the person Eric was talking to, the answer he got back was that Ergocalciferol is the only Vitamin D they are giving out. A week later, Eric had a new appointment with his doctor and decided to ask him about the D2/D3 issue. The doctor said he knew that there was a difference in them both, but could not say what, not even the basic facts I mentioned above. But the doctor stamped a post-it with what he had sent to the pharmacy just to show Eric. “Vitamin D3; 50,000IU tab” is what the stamp said. Eric, off course, got confused and was starting to believe that the pharmacy had made a mistake by giving him Ergocalciferol (D2) since the doctor had given him D3, or at least that is what was stamped on the little note he had. Today, after getting a refill of his Vitamin D he also got and kept all his paperwork that came along with it. Still believing that stamp the doctor had given Eric earlier, he asked me to double and triple check that my definition of D2 and D3 was correct. I did, just for my own sanity, and I was still right. One of the sheets Eric brought me today was the “Patient Education Monograph” sheet stating the drugs and how to use it and so on. The thing that jumped out the most to me was this: Generic Name: Vitamin D – OralCommon Brand name(s): Drisdol, Maximum D3Identification: PA140 Green Oval CapsuleThis is the Drug Eric was given: Vitamin D 1.25 MG softgel; Generic name: ErgocalciferolMy researching mind went into high concentration mood and I started to dig. And this is what I found: The brand name Drisdol is Ergocalciferol (D2), not D3. The Brand name Maximum D3 seems to be hard to find out there in cyber space as a brand name. But the ones I found that were called Maximum D3 seems to be the real stuff, however none of them required a prescription. When trying to find out through the identification number on the pills (PA140) I now know for sure that Eric is taking Vitamin D2 and not the preferred Vitamin D3. The brand name, Drisdol, had the identification W on one side and D92 on the other, but it is still Ergocalciferol. The only conclusion I can draw from all this is that the medical industry does not know or care about the difference in D2 and D3 – it is all same to them. And as long as the pharmacies only give out D2 it does not matter what the doctor prescribe anyway. I know that people are most likely to be prescribed a D2 pill than to be told to buy over-the-counter D3. But it was almost heart breaking to see the letter D and number 3 right next to the drug Drisdol, as we know is a D2 vitamin. It just didn’t make sense to me that they can be labeled as the same type of medication, when we know it is not! Incredible.Why prescribe plant form D2 when you can get perfectly reliable, safe, effective D3--the human form, at the health food store for about $6? Once again, it's the peculiar false bias of physicians and pharmacists: If it's prescription, it must be good; if it comes from a health food store, it must be bogus. Humans need human vitamin D. Plain and simple.For more on the D2 vs. D3 issue, see the Heart Scan Post, The case against vitamin D2.
Weight loss: Different causes, different solutions 1. September 2009 William Davis (8) Heart Scan Blog reader, Kris, related this enlightening story of weight loss (slightly edited for clarity).Kris learned that excess weight is gained through multiple causes. The solutions are therefore multiple, not just one change in diet or two. I started studying about my thyroid issue much earlier and did lose some weight. But ever since I started following Dr. Davis’s blog, it has given me confidence that I was on the right track. I did have my thyroid and iodine figured out from other sources, but Dr. Davis helped me to understand the issues with not only the thyroid but vitamin D3, fructose, fish oil, niacin, wheat etc. I have lost 43lb in last 14 months. It seems to me that there are certain percentages of weight connected with different issues. For example, after I gave up alcohol and sugar, I lost about 14lbs from total weight of 243lbs, weight came down to about 229lb. Then it stopped at 229lb, even though I was in the gym almost 5 to 6 days a week with full workouts. After I changed my thyroid medication to natural thyroid hormones (took synthetic T4 for over 10 years), the weight dropped down further 13lbs or so in matter of few days, shape of the face changed from moon shape/double chin to ordinary long face. Then it kind of stopped at around 213-216 lbs. After giving up wheat, reducing carbs, increasing protein intake (whey protein, chicken etc. no soya, no fructose) the weight came down another 14lbs. Now it is around 200-202lbs and I am over 6.2 tall with heavy set of bones. I feel better than I have ever in my life. More stamina, more clarity/no fog, more confidence and 99% of the time relaxed and being able to see the situation from multiple angles. I use to be able to drink a liter or more jack denial without a problem in one evening but now can’t stand half a can of beer (I miss JD). Drinking alcohol makes me sick. I sleep well and if I wake up in the middle of the night, I have no problem going back to sleep. No more out of breath stair climbing at all. One other thing: I used to be the most attractive meal to the mosquitoes, but not anymore. This year I haven’t been bitten once. I take my dog to the park everyday and I do not use any mosquito repellent, what a relief. I don’t know if it is because of thyroid, iodine, wheat or something else. Skin texture has changed dramatically. I do not use full soap or shampoo, 20% borax, 10 percent of my soap or shampoo for scent and rest water, mixed in a 500ml bottle. No more dandruff, dry skin, pimples for me. Dr. Davis I am thankful to people like you who have the ability to see beyond what you have been taught and have the guts to say the way it is. Most of us work to make living on daily basis but some make their living while spreading their knowledge to save lives. Dr Davis you are one of those few people. Please keep it going.
Calling all losers! 29. August 2009 William Davis (14) I'd like to invite anyone who has followed the Track Your Plaque Break the Weight Barrier program to consider posting their stories and photos on the Heart Scan Blog. Because our focus is prevention and reversal of coronary heart disease, we have not made an effort to catalog the weight loss experience that people have while on the program. For many, weight loss has been substantial. (Several people this week alone have reported weight loss of 9 to 46 lbs in the past 6 months.)It would be helpful to hear and see these results. For those of you who don't mind having a story and photo on this Blog, please come back in future to post your results. You will find this post by entering "weight loss" into the site-specific search bar at the top of the page.
Weight loss and vitamin D 28. August 2009 William Davis (28) At the start of her program, Penny's 25-hydroxy vitamin D blood level showed the usual deficiency at 22 ng/ml. She supplemented with 8000 units of vitamin D. Another 25-hydroxy vitamin D blood level several months later showed a level of 67.8 ng/ml, right on target. But Penny also began our diet, including the elimination of wheat, cornstarch, and sugars, and, over 6 months, lost 34 lbs. Now a much trimmer 146 lbs (still more to go!), another vitamin D blood level: 111 ng/ml. Penny's weight loss means that the vitamin D is distributed in a smaller total volume, particularly a lower volume of fat. This is a common phenomenon with substantial weight loss: lose weight and the need for vitamin D is reduced. The reduction in dose is roughly proportion to the weight lost. Vitamin D should therefore be reassessed with any substantial change in weight of, say, 10 lbs or more, either up or down, because of the influence of fat on vitamin D blood levels. Some references on this effect:Men and women over age 65:Adiposity in relation to vitamin D status and parathyroid hormone levels: a population-based study in older men and women.Obese women:Low 25-hydroxyvitamin D concentrations in obese women: their clinical significance and relationship with anthropometric and body composition variablesObese children:Hypovitaminosis D in obese children and adolescents: relationship with adiposity, insulin sensitivity, ethnicity, and season.African-Americans:Relationship of vitamin D and parathyroid hormone to obesity and body composition in African Americans.Although the bulk of the effect is most likely due to sequestration by fatty tissue, perhaps less sun exposure in obese people also contributes:Body mass index determines sunbathing habits: implications on vitamin D levels.
Grasscutting, fertilizer, and healthcare 25. August 2009 William Davis (23) A guy named Jeff, a 60-something, taciturn, "How 'bout dem Brewers?" kind of guy, cuts my grass. Once a week, Jeff drives over his rust-rimmed 1994 Chevy pickup and trailer, unloads his ride mower, and cuts the grass. For his 40 minutes of work, I pay him $35. For $35, all he does is cut the grass--no trimming, no picking up debris, no working in the garden, no fertilizing, no weeding. Just cutting the grass. Occasionally, Jeff has proven to be a useful resource for peculiar problems. Last year, I had a drainage problem that he helped solve and two years ago he helped diagnose a tree disease that was killing a tree in the backyard; it's now recovered. To save money, and because I like to work in the yard, I do the rest. I trim the edges, I fertilize the grass, plant new flowers and trees, fix damaged areas, trim wild branches.In my view, my relationship with Jeff, a limited, as-needed relationship, in which I ask him to help with specific issues but I manage the rest myself, is how I believe that healthcare should also be conducted. Your doctor should be like Jeff: Perhaps not taciturn, but an as-needed resource available while you do much of the work. My simple relationship with Jeff is, I believe, the healthcare model of the future. You manage your own cholesterol issues, your own basic thyroid issues, supplement and monitor your vitamin D levels, use diet to suit your needs, order blood tests when necessary, even obtain basic imaging tests like heart scans, carotid ultrasound, bone density testing. Your doctor is a resource, near by when and if you need him or her: guidance when needed, an occasional review of what you are doing, someone to consult when you fracture an ankle. What your doctor is NOT is a paternal, "do what I say, I'm the doctor," or a "You need these tests whether you like it or not" holder of your health fate. It is a model of healthcare that will evolve over the next 20-30 years, only in its infancy now. While we started Track Your Plaque as just a resource for in-depth information on prevention and reversal of coronary heart disease, I now see it as something much greater: a prototype for the emerging concept of self-directed health. Enough for now. I've got some tomatoes to pick.
Iodine deficiency is REAL 21. August 2009 William Davis (30) Like many health-conscious people, Kurt avoids salt. In fact, he has assiduously avoided salt ever since his heart attack back in 1995. Lately, Kurt had become tired, often for little or no reason. His thyroid panel:T="glyphicon glyphicon-comment">(6)
Does fish oil raise LDL cholesterol? 17. January 2007 William Davis (1) Katie had an LDL (conventionally calculated) of 87 mg/dl, HDL of 48 mg/dl. She added fish oil, 6000 mg per day. Three months later her LDL was 118 mg/dl, HDL 54 mg/dl. In other words, LDL increased by 31 mg. What gives? Several studies have, indeed, shown that fish oil raises LDL cholesterol, usually by 5-10 mg/dl. Occasionally, it may be as much as 20-30. Unfortunately, many physicians often assume that it's the (minor) cholesterol content of fish oil capsules, or some vague, undesirable effect of fish oil. It's nothing of the kind. Since we based Katie's program on (NMR) lipoprotein analysis, not conventional lipids (HDL, calculated LDL, triglycerides, total cholesterol), I knew that Katie also had a severe excess of intermediate-density lipoprotein, or IDL, and very-low density lipoproteins, VLDL. This signifies that after a meal, dietary fats persist for 12, 24,or more hours. Fish oil is a very effective method to clear IDL and VLDL, though sometimes it also causes a shift of some IDL and VLDL into the LDL class. Thus, the apparent increase in LDL. Another contributor: Conventional LDL is a calculated value, not measured. The calculation for LDL is thrown off by any reduction in HDL or rise in triglycerides. In Katie's case, the rise in HDL from 48 to 54 means that calculated LDL is becoming more accurate and rising towards the true measured value. At the start, Katie's true measured LDL was 122 mg/dl, 35 mg higher than the calculated value. Calculated LDL is therefore approximating measured LDL more accurately as HDL rises. The most important lesson to learn is that, if LDL rises significantly on fish oil and you haven't had lipoproteins formally measured, there may have been a substantial postprandial abnormality like IDL that was unrecognized.
Heart disease is everywhere 16. January 2007 William Davis (0) If you ever need convincing that heart disease is everywhere, you should do what I do: subscribe to Google Alerts and have them forward news anytime the search phrase "heart attack" crosses the web. (Just go to Google, click on "more" to the right of the search bar, and follow the links.)Some recent samples:Workmates resuscitate driver after heart attack A woman coal mine truck driver had a heart attack and required resuscitation with a defibrillator 3 times on the way to the hospital. Heart attack kills groom at receptionA 34-year old man died during his wedding reception, leaving behind his 26-year old new wife.Heart attack ruled as cause of crash An Alabama man drove his pick-up truck into oncoming traffic while suffering a heart attack. Heart-attack victim to return to Hamburg stage Country music artist, Michael Harding, suffered a heart attack and cardiac arrest during a performance. He is apparently recovered and returning to the stage. That's just a sample from the last two days. While you and I are carry on a conversation on reversal of heart disease, our neighbors and friends drop over every day. Even though I witness successful heart disease reversal routinely, the rest of the world is not participating. Pass it on: Coronary disease is identifiable, preventable, controllable, and reversible.
Watch your weight plummet:Be a super vegetarian 14. January 2007 William Davis (0) Here's a neat trick for losing weight: Become a strict vegetarian for 3 days. Before you yawn or say "Yecchhhh!", let me elaborate.Pick some time period. It doesn't have to be 3 days. It could be 2 days, or 5 days, or two weeks. But, for the period you choose, eat only vegetables. No meat, cereals, breads, milk, cookies, etc. Vegetables alone could get monotonous, so make them interesting. Possibilities include:--Hummus--add a little bit of olive-oil, chopped garlic, paprika, red pepper.--Tabouleh--I get mine from Trader Joe's and it's delicious.--Salsa--Low in calories, rich in lycopene and other flavonoids, with no nutritional downside. Also, pico de gallo--chopped tomatoes, onions, jalapeno chiles, cilantro, cucumbers. --Mustards--hot, yellow, brown, spicy, gourmet, horseradish, etc.--Cocktail sauce--i.e., ketchup and horseradish. Use the low-carb ketchup made without high fructose corn syrup. --Tapenades--e.g., olive tapenade made with chopped olives, capers, and olive oil.--Pesto-made with basil, garlic, and olive oil.--Spices and herbs--basil, arugula, peppers, mustard powder, garlic, cilantro, ginger, etc. --Vinegars--wine, Balsamic, rice, apple cider.--Infused olive oils--infused with garlic is especially delicious,e.g., added to hummus.--Bean dips--white bean dip, roasted bean dip, etc.With the varieties of ways to jazz up your vegetables, you couldn't possibly be bored.For example, for breakfast on day 1, eat sliced cucumbers and green peppers dipped in garlic-infused olive oil hummus and a handful of almonds. For a snack, some walnuts, sunflower seeds, sliced zucchini dipped in salsa. For lunch, a salad with an olive oil and balsamic vinegar dressing. For dinner, tablouleh, a cucumber and tomato salad, celery sticks dipped in pico de gallo. All vegetables can be eaten without restricting portion size, since calorie content of vegetables are so low compared to other calorie-dense foods. (See The Heart Scan Blog from a few days back, "One bit or many mouthfuls?" at http://heartscanblog.blogspot.com/2007/01/one-bite-or-many-mouthfuls.html.) This approach works nearly as well as fasting. A half-pound per day weight loss or more is common and painless. You'll also feel great living on low glycemic index foods. (Photos courtesy Wikipedia.)
Dr. Agatston to the rescue 12. January 2007 William Davis (0) Dr. Arthur Agatston, author of wildly successful South Beach Diet, has just released a new book titled The South Beach Heart Program. Dr. Agatston has started on a media speaking circuit to promote his book and concepts. A reporter from Time, who interviewed Dr. Agatston, commented:". . .not enough doctors prescribe niacin for their heart patients, even though the medicine is a proven treatment for raising 'good' cholesterol. Physicians are reluctant, Agatston suggests, because niacin requires diligent follow-up to watch for side effects, taking time that most primary-care practices cannot afford. On the other hand, he says, too many doctors are performing heart operations that represent a financial windfall for hospitals. Bottom line: there isn't as much money to be made in prevention as in treatment."Amen. Dr. Agatston echoes many of the concepts that the Track Your Plaque program advocates. His notoriety is going to help disseminate the idea that 1) CT heart scans are the #1 method to identify hidden atherosclerotic coronary plaque, 2) taking control of your heart scan score is the best way to seize hold of your future, and 3) the present-day popularity of heart procedures like stents and bypass is intolerable, inexcusable, and needs to be reined back.Agatston also brings great credibility and fairness to the conversation and his comments will gain tremendous attention in the press and with the public.
When is a vitamin not a vitamin? 12. January 2007 William Davis (0) When it's a hormone. That's the stand that several researchers in vitamin D have taken and I think they're right. Dr. John Cannell has made a fuss over this in his www.vitamindcouncil.com website. Structurally, vitamin D is most closely related to testosterone, estrogen, and cortisol. You wouldn't call testosterone vitamin T, would you? Vitamins are also meant to be obtained from food. Yes, vitamin D is in milk but only because humans are required to put it there to prevent childhood rickets. Otherwise, the only substantial food source of vitamin D is in oily fish like salmon and then only a modest quantity. Vitamin D is cholecalciferol, a hormone. Deficiencies of hormones can have catastrophic consequences. Imagine that every winter your thyroid gland shuts down and produced no thyroid hormone. You'd get very ill, gain 30 lbs, lose your hair, feel awful. That's what happens when you're sun deprived and thereby deficient in cholecalciferol--you're deficient in a hormone. And it happens to most of us every year for many months. I continue to witness spectacular effects by bringing 25-OH-vitamin D3 blood levels to 50 ng/ml with supplementation, including an apparent surge in success dropping heart scan scores.
An epidemic of heart disease reversal 10. January 2007 William Davis (3) Heart disease reversal is nothing new in my office. However, I have to admit that it's not something that generally happens each and every day. As our approach is refined, we are witnessing an unprecedented frequency of plaque reversal. Since Monday (today is Tuesday), I've seen four people who have regressed their coronary plaque and dropped their heart scan score. Pat was the most recent addition to this list. At age 53, I was honestly surprised at the ease of dropping her heart scan score from 128 to 42 in the space of a year. I was surprised because among her lipoprotein patterns was the dreaded combination of lipoprotein(a) and small LDL, probably the most aggressive risk for heart disease I know of and also among the most difficult to gain control over. She also suffered a deep personal tragedy in her family, an emotional convulsion that can sometimes wipe out any hope of plaque reversal. I'm hopeful that this virtual epidemic of heart disease reversal continues. And I hope that you participate in it.
Second heart scan and heart attack risk 9. January 2007 William Davis (0) At first, Joe felt disappointed, defeated, and frightened. After his heart scan, a radiologist at the center told him that his score of 264 was moderately high. He told Joe that he was at moderate risk for heart attack and that a nuclear stress test was going to be required. This left Joe feeling confused. After all he'd had a heart scan 18 months earlier and his score was 278, 5% higher. I reassured Joe that the radiologist had not been aware that Joe had a prior heart scan. The radiologist didn't know that Joe's heart scan score had actually been reduced. In fact, Joe's risk for heart attack was not moderate--it is now very low, since his score was 5% lower. While growing plaque is active plaque, shrinking plaque is inactive plaque and thereby at far less risk for heart attack.I wrote about this phemonenon in a previous Blog: When is a heart scan score of 400 better than 200? at http://heartscanblog.blogspot.com/2006_09_01_archive.html. When you've had more than one scan, the risk for heart attack suggested by the score takes a back seat to the rate of change of your score. In other words, even though Joe's score of 264 represented a moderate risk (of approximately 3% per year, roughly 30% over 10 years), this no longer held true, since it actually represented a 5% decrease over a previous score. Joe's risk for heart attack is probably close to zero. ALWAYS view your second (or any subsequent) heart scan score in the context of your previous score, not in isolation.

Heart scan curiosities #5 8. January 2007 William Davis (1) Despite the controversy over drug-coated stents, I maintain that the best stent is no stent at all. Yes, there are indeed times when such things are necessary, but not with the frequency that they are implanted nowadays. Another reason why stents are an undesirable phenemenon is that they muck up your heart scan. Take a look:The long white object in the center is a stent in the left anterior descending artery of this 60 year old man. Just beyond the stent (at about 1 o'clock from the stent) is a plaque that could be scored. However, you can see that, with the presence of the stent, the bulk of this artery is no longer "scorable". If this man wishes to "track his plaque", he will have to be content with tracking only the circumflex and right coronary arteries, the other two arteries without stents. The stainless steel or similar metallic materials of current stents simply prevent us from seeing through them for plaque scoring purposes. It's best if you can simply avoid getting one for this and other reasons.Track Your Plaque Members: Watch for the upcoming editorial by our Heart Hawk on drug-eluting stents.
