Take Vitamin D3 For Optimum Health

January 3, 2012 by  

Are you on a daily regimen of D3? I take 30,000 units per day, and I give my wife 20,000 units because she weighs about 100 pounds less than I do.

Vitamin D is a key player in having and maintaining total health. Its benefits are unbelievable!

Vitamin D is a potent neuroregulatory steroidal hormone that influences nearly 3,000 of our 25,000 genes! That’s big, and big important!

Vitamin D influences dozens of conditions, with emphasis on those related to heart disease, yet there is a broad epidemic of vitamin D deficiency in America. Some dependable writers say that up to 85 percent of Americans have insufficient vitamin D levels.

Please, please pay no attention to the so-called recommended daily allowance (RDA). If you do, you will pay a very high price.

Vitamin D influences dozens of conditions. Here are a few: cancer, heart disease, hypertension, obesity, diabetes types I and II, cold and flu, aging signs, osteoporosis, seizures, Alzheimer’s disease, dementia, schizophrenia, inflammation, inflammatory bowel disease, multiple sclerosis, infertility, depression, asthma and many more! What would it take to get people on a very low-cost vitamin D supplement?

Also, I recommend taking high dosages of vitamin D3 (50,000 IUs) before surgery for a far greater chance of quick recovery and survival.

    Where is the science behind this recommendation of 30,000 iu of vitamin D-3/day? Did some doctor or researcher recommend this? Has someone used this much D-3 in the past and had success with treating an ailment? Or was this just pulled out of thin air? I’m very curious how you arrived at that amount of D-3. Thanks.

      Joe, you’re asking the wrong question. A better question would concern WHY the AMA crowd, the FDA and the criminals at Big Pharma don’t want Americans to have what we need.
      Any American MD who tells you to ‘watch out for D3 toxicity’ is a QUACK. The latest RESEARCH says that Americans are at risk because the AMA, FDA and Big Pharma cabal wants American to stay at risk via doses of D3 that are far too LOW.
      STOP having so much faith in those who should know better but never hesitate to put MONEY before lives. WAKE UP!

      • Chris

        I’m sorry but you are just insane. Vitamin D toxicity is a very real issue.

        I am only taking 10,000iu/day D3 and am having major problems keeping my manganese whole blood level above the bottom of the range, even while taking 50mg/day of manganese (> 4x UL), at a Vit D blood level of 82ng. One of the many things Vitamin D does that makes it ‘magical’ is it increases MnSOD, which while a great thing it can end up depleting manganese in your body if you don’t get enough of it. Before I realized my underlying problem was low manganese the Vitamin D made me pretty sick at 109ng. Toxicity from any vitamin/nutrient tends to be due to the fact it runs other nutrients low. B-6 vs copper is another example, etc. Some other important nutrients that are involved with Vitamin D are magnesium, and Vitamin K.

        That said if I can ever get my manganese level to rise I will likely bump up to 20,000 iu and see what happens.

      • Chris

        To follow up on what I said.

        It is very important to get regular blood tests if taking megadose vitamins to make sure everything is tweaked out properly. There are quite a few places on the internet that resell any Labcorp test you want and a few that also sell SpectraCell MNT, hair mineral tests, and various other alternative tests. It’s not cheap but what is your health worth to you? :-)

        As an example a single manganese test runs around $200.

    • Jpb

      I do think 30,000 is a heck of a figure of Vit D. I have been following Vit. D for some time. The latest research is around 5000, I.U. , but if you have an ailment around 8,000 I.U daily. I take aroun 5000 I U. daily or at least I try . Dr. Jonathon W. Wright recommends around 5000 daily, if I remember this quite well.

  • David in MA

    Holy cow! 30,000/50,000 units a day? Is this IU’s a day?
    My lab work shows I am at the bottom of the chart in D3 level and a doctor (MD) at/in what they call “INNOVATIVE MEDICAL CARE” has prescribed 6,000 IU a day to bring my level up (I am also on a foiliate for high homosystine, now, I go to a VA doctor who is not concerned with my D3 or homosystine.) One MD who is open to “alternative/complimentary medicine” and another who has to be clessified as “mainstream medicine”. (p.s., no matter what is prescribed I always research the medicine and then question the doctors as to why I need it..this can upset the doctor sometimes. One doctor told me once that I read to much, I responded that it’s my body and my life and I want to know the what’s & why’s.
    I have been using vitamins and some minerals for years and unless our “intellegent” government officials at the FDA outlaw them I intend to continue using them…….but I research everything I intend to use, not only at one reference but several because some have info othets do not.

    • David in MA

      BTW, Vitamin D is not a vitamin, it’s a hormone… :>)

      • Karolyn

        I think you’re wrong.

        • Bob Livingston

          Dear Karolyn,

          David in MA is correct. From the Vitamin D Council: “Vitamin D is not really a vitamin, but one of the oldest prohormones, having been produced by life forms for over 750 million years. Phytoplankton, zooplankton, and most animals that are exposed to sunlight have the capacity to make vitamin D.

          “In humans, vitamin D is critically important for the development, growth, and maintenance of a healthy body, beginning with gestation in the womb and continuing throughout the lifespan. Vitamin D’s metabolic product, 1,25-dihydroxyvitamin D (calcitriol), is actually a secosteroid hormone that is the key which unlocks binding sites on the human genome. The human genome contains more than 2,700 binding sites for calcitriol; those binding sites are near genes involved in virtually every known major disease of humans.”

          Best wishes,

    • Karolyn

      I had a gastro 10 years ago who wanted me to do chemo for HepC, which I declined. I went on a heavy vitamin & supp. regimen. 3 years later I had a second biopsy with better results than the first. Of course, he dismissed my assertions, as he sat in his “throne” in his expensive silk suit. I have always been in pretty good health and declined the chemo because it would have ruined my health. To this day I remain healthy, and my liver is fine. It kills me how many people just follow doctor’s orders without question. There are so many like that – probably the majority. That’s why the healthcare system in this country is so screwed.

      • s c

        K, there are many reasons why American healthcare is so ‘screwed-up.’ MDs who don’t think independently is only a part of it.
        Think of Uncle Scam as a fake MD who demands that we see the old fart as THE greatest MD of all time. Can you see anything wrong with that? Do you really think the W H idiots are making healthcare any better by forcing an inherently corrupt system on us? K, force is NOT justice or compassion or reason. FORCE is FORCE.

  • Chet Schaeffer

    My understanding is that D-3 improves absorption of calcium. Too much calcium can cause kidney stones, so I read in my research of D-3. Supposedly anything over 2000 units per day can lead to stones.

    • Suzie O’Day

      Where did you see that?

    • JC in CA

      Hi Chet, I recommend researching 100% cranberry juice (the tart stuff, not the cocktail fruit punch) for stone concerns or elimination.

    • Karolyn

      8000 units is generally acceptable. However, everyone should be tested first. Don’t take D2.

    • s c

      Don’t think that way, Chet. MDs are SUPPOSED to be experts on nutrition, but they’re not. They were indoctrinated at medical school, and if given a chance they will make your decisions.
      Medical politics won’t do anything for your health, so don’t give an MD a chance to make your decisions. Toxicity doesn’t apply to D3. ‘D’ is another matter.
      An ‘education’ is one thing. KNOWLEDGE is something else.

    • Chris

      Take Vitamin K with it and that will probably help some.

  • http://- gavriel eskel

    how much is 1 unit? one drop or what? please tell in plain language
    for us innocents

    • libertytrain

      the bottles of vitamins will tell you how many units there are in that particular vitamin. Vitamin D 3 comes in assorted “unit” sizes. Some will say, 500 units, some 2,000 units. Just read the bottles.

    • Chris
      Converting International Units (I.U.) isn’t so simple–because it’s a different conversion for each nutrient. The I.U. is an arbitrary amount based on the amount of a given nutrient needed to produce a biological effect. Here are the conversions for the most common nutrients.

      Nutrient Amount in “1″ I.U.
      Vitamin A 0.3 mcg
      Beta-carotene 3.6 mcg
      Vitamin D 0.025 mcg
      Vitamin E 0.67 mg

  • RadiantTara

    There is plenty of research out now that supports much higher doses than were originally suggested. The RDA is way off and you will be deficient if that is your only source for this crucial hormone.

    15 minutes of direct sunlight produces in our bodies 20,000 IUs. So if we were living Paleo as all our ancestors in sunny areas we would be getting close to half a million IUs a day. One of the reasons people are falling apart today is we were told to stay out of the sun which we used to be in all day long.

    For quick takes on Vit D go to

    I personally take 20,000IUs a day and I am great. I take even more if I get the sniffles. Studies now show Vit D is more effective than Flu shots. People that live near the equator don’t get colds and flu, unless they have immune problems.

    Soon what seems like mega doses will be accepted as the norm. Average doctors sadly have not caught up. Maybe because proper use of the sun and Vitamin D would put them and drug companies out of business. I know people that were on multiple Depression Meds that were just severely Vitamin D deficient. A years supply of Vitamin D cost around $10. The drug companies do not want the doctors to know the power of Vit D. You realize, I hope, that everything a doctor knows to tell you is coming from the drug companies, not clean science or even common sense.

    • Frank Verano

      Everybody should visit and see the presentation. It is a real eye opener. It shocked me that 89 percent of the older people take prescription medications. I am 94 years old now and I don’t take any medications, prescription or otherwise. Supplements, yes, since 1937.

  • Joanne Waldron

    While I feel that adequate vitamin D levels are important, taking that much vitamin D willy nilly is a very irresponsible suggestion, imho. People need varying amounts of vitamin D, and the only way to know what your personal levels are is to have them tested. One study showed that even doctors themselves are often deficient in vitamin D, and most people (particularly overweight or elderly people) are deficient. However, there is no way to just “guess” how much you should be taking. This is an individual thing, and it is possible to take too much.

    • John

      I agree with everything but the last comment. I don’t see anyone taking to much vitamin D. Maybe you mean that to much is over kill.
      The leading cancer expert on stress related disease takes 50,000 IU’s daily and 150,000 IU’s if he thinks he needs a boost to his immune system.

    • jeanelane

      I agree that you can take too much. Vitamin D is a fat soluble vitamin, which also means that it gets stored in your fat cells, like vitamin A or E. Just because something is good does not mean that more is better. My doctor has put me on ~6000 IU / day until I get tested.

      • s c

        As the article says, jeanelane, take D3 and stay away from ‘D.’ Most MDs don’t think about the difference between D3 and D (they’re making too much money by focusing on their cash flow). Self-educate, and STAY AWAY from over-educated quacks.

      • Chris

        What S C means is prescription Vitamin D generally in the US is actually Vitamin D2, the type you can buy at stores is Vitamin D3.

    • Karolyn

      It is recommended that you get your D level checked.

  • John

    Have your blood checked for the level of vitamin D.

    Normally it should be 50-70 ng/ml.

    For healing and prevention 70-100 ng/ml.

    I take 20,000 IU’s daily reguardless.

  • Neal

    Anyone with glaucoma or high intraocular pressure might be well advised to take D3. I take 5000 IU per day as one of several dietary changes to keep my pressure normal without meds. It was 5 years ago a doctor told me I’d wake up blind any day! My eyes are now normal and I don’t wear specs.

    I am concerned about recent links of high D3 and other ailments. I’m guessing 50,000IU would be considered on the high side!

  • s c

    Two other sites are 1) and 2)

  • Steve

    My Doc put me on 50,000IU/week for 6 months. The day after I took my first capsule I felt better. I stopped taking Claritin every day. No cold or flu since starting it.

    That was almost three years ago and I moved to 10,000IU/day and have not missed a single day. Use must use quality D3 though, Walmart didn’t work and neither does the stuff from my pharmacy. I get mine at a health food store.

    I tell everyone who has ears about it……….

    • s c

      Right on, Steve. Bargains are nice when you’re shopping for supplements, but it takes QUALITY ‘to get the job done.’ How often do you get checked to see what your D3 levels are?

  • Incredulous1

    Guess I need to triple my 2000IU once a day dose. Someone said, “a year’s supply is only ten bucks.” Well, I would like to find that Walgreen ’cause mine costs about $10/month. Also, I have yet to hear any recommendations on best brands or where to buy? Are all D3 sup.s the same? Do some absorb better than others? I hate to see bright yellow pee and realize all those vit.s (and dollars) are getting flushed down the crapper.

    • Karolyn

      Dr. Mercola has a spray that is probably the best you can get. Of course, it is more expensive. I just got drops at, which I have been buying from for 10 years. They have the best prices on all brands. Lately, I’ve just been getting it at WalMart. They have specials on 2 bottles for $6.99.

      • libertytrain

        the D3 5,000 run around $19.99 a bottle at Walmart, Kmart, Walgreens etc., they do vary depending on the units. And best to wait as Karolyn says for the buy one get one free sales. I just got that deal at Kmart

        • s c

          libertytrain, way too many people look at vitamin supplements the same way they look at gasoline (little or no thinking is involved. all I need to do is ‘buy it’ and get on with my life).
          Stick with reputable name brands, and that usually means staying away from ‘discounted’ cheapies that can be had almost anywhere. Any supplement that’s not a “quality first” product is a waste of time and money.

          • libertytrain

            yes, you’re right however it is not correct to assume that all vitamins sold at Walmart Kmart Walgreens etc. are inferior.

    • Bob Livingston

      Dear Incredulous1,

      From the Vitamin D Council: Vitamin D3 is real vitamin D, for it is the same substance as what is produced in human skin in response to sun exposure. Supplemental vitamin D3 is derived from either lanolin or cod liver oil extract and is the form of vitamin D that most effectively treats vitamin D deficiency.

      Just be sure you are using supplemental vitamin D3 and not pharmaceutical D.

      As to your bright yellow urine, that can be a sign of dehydration. Your urine should be light straw colored to clear if you are properly hydrated. The color may not have anything to do with voiding the vitamins you have taken.

      Best wishes,

      • Karolyn

        I believe it’s vitamin B comples that colors urine.

  • conserve

    Been a type 1 diabetic for 57 years and have many of the complications. I started with supplements about 11 years ago and think they’ve helped lots. Along with vit D3 at 10 000 IU during the winter and 6000 IU during the summer when I’m in the sun more, all the supplements have helped. Used to wonder if this was too much D but am no longer concerned.

  • Sunnyarizona

    I have been taking increased doses of Vitamin D for a long time, Started to help my bones. I was diagnosed with Osteopenia years ago. Today, I take supliments of D equal to 6,000 IU’s a day. I get more than that of course from my food too. Since I started this regimen, I NEVER get sick. NO COLDS….I have not taken flu shots for 10 years, and I know that they are NOT good for you, and I know I DON’T need the shot!
