Vitamin D2 vs. vitamin D3

An interesting question came up on the Track Your Plaque Member Forum about vitamin D2 vs. vitamin D3. This often comes up among our patients, as well.

Vitamin D is measured in the blood as 25-OH-vitamin D and is distinct from 1,25-diOH-vitamin D, a kidney measure, a test you do not need unless you have kidney failure.

The human form of vitamin D is cholecalciferol and is usually obtained via activation of a precursor molecule in the skin on activation by the sun. You can also take cholecalciferol and it increases blood levels of 25-hydroxy vitamin D reliably.

However, there is a cheap, plant-sourced, alternative to vitamin D3, called vitamin D2, or ergocalciferol. D2 has far less effect in the body. Taking D2 or ergocalciferol orally is an extremely inefficient way to get D. Unfortunately, it's the form often used in milk and many supplements, even the prescription form of D. About half the multivitamins and calcium supplements I've looked at contain ergocalciferol rather than cholecalciferol.

Taking vitamin D2 yields very little conversion to the effective D3. This particular issues is maddening, as the USDA requires dairy farmers to add 100 units of vitamin D to milk, and D2 is often used. In other words, the D in many dairy products barely works at all. There are many children who rely on D from dairy products who are at risk for rickets and are not getting the D they need from dairy products because of this cost-saving switch. Do not rely on milk for vitamin D for your children.

D2 or ergocalciferol is often included in the blood measures of vitamin D along with vitamin D3. The only reason it's checked with blood work is to ensure "compliance,", i.e., see whether or not you're taking a prescribed ergocalciferol. Beyond this, it has no usefulness.

25-OH-vitamin D3, or cholecalciferol, is both the blood measure and the supplement you need. This is the one that packs all the punch. Keep in mind also that it is the oil-based gelcap you want, with more consistent and efficient absorption. Tablets usually barely work at all, even if it contains cholecalciferol. Most people who take calcium tablets with D, or multivitamin with D, not only are getting a powdered form of D, but also in trivial doses. It's the pure vitamin D3, cholecalciferol, in gelcap form you want if you desire all the spectacular benefits of vitamin D.

    It's good that you explained how vitamin D3 is better than vitamin D2.

    Your readers should also know that, depending on their skin type, just one or two sessions in a tanning bed will produce all the healthy vitamin D3 a human body can use.

    Moderate tanning is healthy behavior.  Don't sunburn.

    Dr. Davis, your blogs on vitamin D are terrific.  I am a colleague of Dr. John Cannell, and am presently coauthoring a book with him.  It will deal with the effect of vitamin D supplementation on athletic performance.  He has also endorsed my current book on the health benefits of sunlight and vitamin D.  If you would like a free copy of that book--Solar Power for Optimal Health--please contact me at megamarc1@aol.com or call me at 435-628-3102.  

    Keep up the good work!

    Re vitamin D consumption, do you have any thoughts re this study?  I'd like to recommend to my parents that they take an oil-based Vit. D supplement (they're in their 70s), but that study gave me pause.

  • Dr. Davis

    Unfortunately, the study was only in abstract form, meaning none of the full details were available.

    Nonetheless, several uncertainties:

    What was the calcium intake? What was the vitamin D intake and what blood level of 25-OH-vitamin D3 was obtained?

    I suspect that few of the participants had even normal vitamin D blood levels. The majority of vitamin D preparations in calcium tablets barely work at all due to poor absorption.

    However, I do worry that, with appropriate D supplementation, the doses of calcium many people take is excessive. The true need for calcium is likely far less when D is fully replenished.

    I would not make any firm judgments based on this preliminary report. Interesting issue, however.

    Hi Dr Davis,

    I'd been persuaded, like you, that D3 is the form of Vitamin D to use for maximum effect.  Now comes this study:

    "Vitamin d2 is as effective as vitamin d3 in maintaining circulating concentrations of 25-hydroxyvitamin d"

    J Clin Endocrinol Metab. 2008 Mar;93(3):677-81. Epub 2007 Dec 18.

    Dr Holick uses Vitamin d2 in treating his patients.

    He was recently interviewed on the radio program the People's Pharmacy; the interview is available as a podcast.

    So, if I am buying a supplement that is labeled as Vitamin-D (not D3), but the label says it is 1000 IU of Cholecalciferol, the supplement is really Vitamin D3?

    Actually your post is very confusing because you say vitamin d3 is 25-oh-d3, actually it's a metabolite of d3, also you say ergocalciferol is inneficient because yields little conversion to 25-oh-d3, but d2 converts ONLY to 25-oh-d2 and very efficiently, and has similar activity to the d3 form(about 2/3 of the potency), the bad about d2 is also that has faster metabolism than d3.
    All in all, d2 is efficient, not like d3, but it's not useless like you say, and d2 has metabolites with potent anticancer activity, similarly to tamoxifen in breast cancer, so d2 has it's own benefits over d3.

    Vitamin D2 Is As Effective As Vitamin D3 In Maintaining Concentrations Of 25-hydroxyvitamin D, Study Suggests

    Sorry blogger, but you have been proven wrong.

  • Anonymous

    9/24/2009 11:21:46 PM |

    The difference as I've understood - there are actually 5 forms of Vitamin D (D1-D5). Vitamin D2 must be converted to be used, Vitamin D3 is used directly. Vitamin D2 is "relatively ineffective" because it is the  stored form and it's stored in the body's fat- which is why it has certain properties that D3 doesn't possess for fatty tissue health. Eventually D2 effectiveness would equal D3 because the body eventually converts what it needs. However, it has requirements for the conversion, and if taken for anti-inflammatory, anti-cytokine storm, immune modulation, then D3 is the much better form since it can be used immediately. When healthy I take D2 and D3 - D2 fills the body's stores while D3 is consumed. When the immune system is being challenged Vitamin D3 is the better form and will keep the D2 levels in the fat unaffected.

    As far as calcium supplementation - I think it's ludicrous - I can't imagine anyone, other than people that cannot tolerate milk products, not getting enough dietary calcium. I think that's one of the biggest myths propagated today. Hypercalcemia, and even just excessive calcium intake, has been shown to cause brain lesions in elderly, and calcium creates issues when Vitamin D is supplemented.   Magnesium supplementation is MUCH more important for everything from healthful bones, heart rhythm and heart attack protection, to smooth muscle relaxation, and mental acuity. We need a MINIMUM of 400mg and should be taking more.  With everyone drinking bottled water that has next to no magnesium content, we are all susceptible to dangerously low "sudden heart attack" levels of magnesium.

    For vegetarians (where killing of an animal is prohibited) -
    D3 made from lanlolin (sheeps wool) is the only choice, there is no pure plant based D3?

    For Vegans (has to be plant based only)
    Looks like D2 made from yeast is the only choice.
    If any one know best form of D3/D2 suitable for vegetarians/vegans, please post where one can get (Please note, gel capsules are made from animal sources, they would not be suitable). Thank you

    I'm taking a vegan calcium supplement, with vitamin D3. Its branded Vitamin Code, RAW CALCIUM, from Garden of Life, its fortified with Magnesium and other things. Its vegan, and RAW. I think the D3 source is algae.

    Sorry Steve. The code RAW vitamins you're talking about aren't vegan. They get their D3 "primarily from lanolin" (=occasionally fish?). According to them, since they remove the traces of lanolin during processing, they felt that it was vegan.

    After listening to them go on and on with their justifications of it and why it was vegan, it just felt like a giant marketing scheme. Needless to say, I'm now quite wary of all Garden of Life products.

    Regardless, they're still in the process of changing labels, but in the meantime, nope, not vegan. Frown

What would life be like . . . ?

What would life be like . . . ?

What if coronary heart disease could be prevented--no eliminated--applying methods that were accessible, easy, and cheap?

What if coronary heart disease and, thereby, angina, heart attack, sudden cardiac death, ventricular tachycardia, heart failure, and the cerebrovascular equivalent, stroke, could be eliminated using readily available tools available to virtually everyone in the U.S.? And, over a year, it cost less than a once-a-week latte at Starbucks?

How would the healthcare landscape change? What would become of hospitals, manufacturers of the billions of dollars of hospital equipment necessary to supply the cardiovascular hospital industry (e.g., stent manufacturers, catheter manufacturers, defibrillator and pacemaker manufacturers, pharmaceutical manufacturers who no longer have to produce the volume of antiplatelet agents, inotropic drugs, antiarrhythmic agents, etc.)?

How would our lives change? What would the end of life look like if people stopped dying of heart attack, sudden cardiac death, congestive heart failure at age 55, 65, or 75, but lived out their lives to die of something unrelated?

What if the solution had little or nothing to do with drugs but evolved from simple nutritional strategies, supplements meant to correct the deficiencies that accompany modern lifestyles, and a few unique strategies targeted towards the genetic predispositions that lead to heart disease?

What if all this were possible at a cost of a few hundred dollars per year?

It would certainly be a cataclysmic change. Hospitals would shrink to a small remnant of their current gargantuan, dozens-per-city presence. The need for hospital staff would be slashed by over half. The rare cardiologist would tend to congenital heart disease sufferers and other unusual forms of heart disease and he or she might have a colleague or two in all of a major city.

Healthcare costs would plummet, no longer having to sustain the enormous cardiovascular healthcare machine of hospitals, staff, industry, and long-term care. Health insurance, private or public, would drop by 50%.

It would free up nearly a trillion dollars that could be redirected towards other pursuits, like schools and research. Extraordinary leaps forward in quality of life and science would emerge, given that magnitude of funding.

It's not as grand a thought experiment as Alan Weisman's The World Without Us, in which he imagines what the world would be like without humans altogether.

How long would it take to recover lost ground and restore Eden to the way it must have gleamed and smelled the day before Adam, or Homo habilis, appeared? Could nature ever obliterate all our traces? How would it undo our monumental cities and public works, and reduce our myriad plastics and toxic synthetics back to benign, basic elements?

But I believe this thought experiment--what would life be like without heart disease because it was eliminated using inexpensive tools-- is more plausible, more likely to occur. In fact, it has already begun to occur.

See those vines growing up the side of the hospital?

    What would life be like without CVD deaths?

    For a while, the way you describe. But as more people lived into their 80s and 90s the rate of dementia would rise dramatically.

    If you visit any dementia facility you will find it is full of normal weight people many of whom are in otherwise "excellent" health--that's what got them to live to 88 or 92.

    But once demented, their lives are tragic. Saddest are those who are just demented enough to be totally confused, but not enough that they are oblivious to their condition. All people with moderate dementia  need round the clock care which is not covered by Medicare unless they have no assets. This depletes the savings of humble people who have worked for decades who are left with nothing to leave their children.  Depending on the cause of their dementia people may need full time care for a decade. Once they have no money they are turned over to the warehousing of nursing homes, many of which are horrendous  where those who are still conscious may pray daily for death.

    Right now one half of those in the 80-100 age group are demented. The humiliation  dementia inflicts on loved ones is so terrible that anyone who has a relative in this condition (and we have two in our family) will pray that they have enough heart disease to take them out before they go through that long, slow degrading decline.

    Many people have unrealistic ideas that they could take care of a loved one with dementia which stem from not having been put face to face with it since the truly demented are usually locked away somewhere.

    Note too that though there are attempts to blame dementia on diabetes, I don't buy it. The rate of dementia has climbed with the climb in lifespan though "senile dementia" has always been the fat of a good portion of those who lived to be old-old.

    The diabetes diagnosed late in life is part of the gradual failing of their organs and often not the same as diabetes diagnosed in the 40s. It may be associated with dementia but it is far from proven that it is causative.

    Beside that, eliminate CVD and the rate of people dying from the prolonged agony of cancer would go up too, because the older people get the more likely they are to develop cancers. Something many people don't know is that chemotherapy administered to older people id prone to cause dementia. It causes mild cognitive problems  in younger people too, but in the old-old it is much more likely to take out their memories.

    I'm all for eliminating the kind of CVD that takes people out young, especially since it is so often linked to genetic abnormalities.  But for those in their 70s and beyond, eliminating CVD might simply be to trade one condition for another far worse.

    No one lives forever.

    It sure doesn't seem like that will happen anytime soon, at least not here... I spent all day calling around to local docs (including cardiologists) and NO ONE had even heard of advanced lipid testing...  I'm ashamed to say that I work for a large hospital system that wants to be "cutting edge" and all about research yet they have no knowledge of basic preventative care in regards to the leading cause of death in our country?!!

    Is advanced lipid testing really that advanced?

  • JPB

    7/29/2009 3:25:12 PM |

    That is part of my dream, too. But first, people have to have access to correct information, stop being so passive with medical professionals  and then take an active role in establishing and maintaining their own heath.  The real "health" care reform would do everything that you say but would come directly from the people who are receiving so-called medical "care."

    Of course, the vested interests will fight this tooth and nail but it would be tough to stop if our population would finally wake up to the way they are being manipulated!

    Hi, Jenny--

    Thanks for your thoughts.

    But I would rather succumb to dementia at age 90 (that I helped delay with vitamin D and other mental-preservation methods) than heart attack at age 59, bypass at age 60, three stents at 63, four more at age 68, living a life of hospital revolving doors. Don't forget about the defibrillator that aborts the ventricular tachycardia that comes from the scar in your left myocardium from the original heart attack.

    Millions of people live this way and have not been told that it doesn't have to be this way. That's what I'm talking about.

  • Dr. William Davis

    7/29/2009 4:28:29 PM |

    Lucy--

    NOT having advanced lipid testing impairs the identification of the causes of heart disease. It is a big step towards better control over heart disease risk. It identifies treatments that often have nothing to do with more need for medication--that's why your doctors don't know about it.

    You probably already know that the bulk of medical "education" does not come from journals or scientific publications, but from the pretty drug representative with dinner invitation in hand waiting in the doctor's waiting room.

    I am with you! And to be honest – it is actually horrible WRONG that we are not yet there. We (or at least many people) already know how to escape the dreadful C V and D. Why it is not already implemented in every hospital, doctors’ office, and even in education is scary! But most of it has got to do with a short-term money flow, I would guess.

    As boldly as I think we can put most cardiologists out of business I also believe we can eliminate many cancer diseases by natural remedies!

    No one has to believe me, but sometimes we are to do ourselves a favor and listen to those who have the degrees to say and act upon statements. What about these well selected and bold statements:

    John P. Cook M.D. Ph.D. in his book “The Cardiovascular Cure – How to strengthen your self defense against heart attack and stroke” In his book you can read this: “There is magic within all of us. It comes in the shape of a molecule known as nitric oxide.  A substance so powerful that it can actually protect you from heart attack and stroke.  Best of all your body can make it on its own.  Nitric oxide is your body’s best defense against heart disease.  The body is capable of healing itself.  What you do with the magic is up to you.”

    Dr. Louis J. Ignarro; Nobel Prize Laureate in Medicine, 1998; “NO more heart disease – How Nitric Oxide can prevent, even reverse, heart disease and stroke” and you can read this in the book: "You do not have to wait for the rest of the world to see the light--and the drug companies to put new Nitric Oxide-based prescription drugs on the market--in order to take advantage of what Nitric Oxide has to offer.  Even if you have high blood pressure, have suffered a heart attack, or are at high risk...You can beat the odds.  The power to lead an entirely new and healthier life is in your hands.  Carpe Diem--Seize the day!  Start boosting your Nitric Oxide production right now!“

    Dr. Jonathan S. Stamler; Professor of Medicine; Duke University Medical Center - "It [Nitric Oxide] does everything, everywhere. You cannot name a major cellular response or physiological effect in which [Nitric Oxide] is not implicated today. It's involved in complex behavioral changes in the brain, airway relaxation, beating of the heart, dilation of blood vessels, regulation of intestinal movement, function of blood cells, the immune system, even how fingers and arms move.“
            
    What these gentlemen are talking about is Arginine (arginine transforms into Nitric Oxide once in your body). And Arginine has also been found to: “Improve Memory & Cognitive Functions” (J Physiol Pharmacol 1999), and “May inhibit the division and proliferation of cancer cells” (Br J Surg. 1997)

    The list goes on and on… Arginine 5gr or more a day along with Citruline and antioxidants on a daily regularly basis can do all these things and we can at the same time fight cancer and dementia! It is all out there in the nature for us to use!!!

    Yes I see both your points. I strongly suspect I am going to die significantly younger than others in my family thanks to the clueless doctors who decided not to diagnose my diabetes, and worse, put me on a high carb low fat diet to "cure" my appalling lipids.

    On the one hand going quick of a heart attack while in my prime would be far preferable to what happened to one of my mother's friends: after a quad bypass she gradually declined from being a fit active sociable person to someone who was blind, deaf and incapable but whose heart would NOT stop and give her the release she prayed for. Once you get into that state they can warehouse you for years.

    My mom was one who met Jenny's tragic fate.  She did Pritikin and McDougall for years, decades actually.  Though she was a lawyer, played piano and read constantly, Alzheimer's (or a similar dementia) overtook her in her 70s.  She spent several years with caregivers in her home, and then six long years in a deluxe nursing home, burning up all the assets she had saved her entire life.  All we could do was watch.

    I believe the low-fat diet she followed wasn't what her brain needed.  She was probably chronically starved for EFAs, especially Omega-3.  But we didn't know what we know now, so we couldn't help.  Of course, I can't know for sure this was the causative factor...maybe this is just my defense mechanism.  But I think Dr. Davis's point is that addressing CVD in no way excludes also addressing dementia.  There's tons of exciting research being done.  Plenty of folks make it to the very end with all their faculties intact.  Why?

    Dr. Davis,

    What is your opinion on genetic testing and it's potential effect on the treatment of both CVD and (since it's been mentioned in this discussion) dementia?   I know both my ApoE and KIF6, and find it all very fascinating.  I am a 4/3 and a noncarrier for the risky form of KIF6.  I do think there are some potential ethical concerns with genetic testing, but I do see benefits as well.  For instance, supposedly my KIF6 result means that I would likely not benefit from a statin.  So, it's extra leverage in my mind when discussing treatment options with my cardiologist.

    From what I have learned here and in other like minded blogs (Eads, Stephan, Hyperlipid, BG and others)it seem that the whole metabolic syndrome can be prevented + autoimmune diseases and probably many cancers. This has the potential of really emptying out the hospitals and leaving maily the preventative medicine heroes like yourself and Eads in the front where you belong
    I have recently started a blog in Israel, translating to Hebrew some of your (and  the other's) posts. The spreading of ideas resemble sometimes the spread of epidemics. It picks up suddenly so lets be optimistic!
    keep up the good work!

    Dr. Davis,

    Life without CVD is not something that can be dreamed about, but rather something that existed in the recent past.  I have heard stories from MD's who served in the US military during the Korean and Vietnamese wars, and while over there, and in Japan, during those years, were asked by local doctors to call them when the military MD was treating a patient (usually American) for a heart attack or having a heart problem, because they had never or very infrequently seen those kinds of problems in their practices, and wanted to see what it was all about.  So, some parts of the world escaped CVD problems already!

    Hi, DIB--

    Excellent point!

    I agree: Many lessons are being RE-learned.
