If you have a deficiency of Vitamin D, as determined by a blood test, you may need 1 or 2 of these per day (5,000 to 10,000 IU). There is no toxicity at this level if you actually need to be taking it because you have a deficiency. You should have a lab test to get accurate results and talk to your doctor about what dosage you really need.

IU means international unit. Its a common unit of measure used around the world. My name is Greg L. and I've been a registered nurse for over 12 years. My passion is educating people on natural ways of healing the human body and prevetion of disease. I use 5000iu of Vitamin D3 every other days to avoid toxicity.

Very few people need 5,000 IU and bought it only because of all the great reviews on the site, there were many people who liked the high dosage. I had a strange reaction, just felt off for a few days so I went down to 1,000 IU (I had to buy another bottle, these are liquid gel pills), which my doctor said was all that was needed and she was correct. I might build up to 5,000 someday, but not sure if it is needed, a check up or lab report is a good idea but it is very expensive. I would buy the 5,000 IU at your own risk, not a comfortable feeling if you are sensitive to it.

International Units. You really should ask a doctor before taking this. While most people will benefit from taking it, there are some cases where you shouldn't. You need to know how much to take and you really should know what your current Vitamin D level is before starting. This way you can modify the dosage accordingly.

Dear Emma, There is actually very little difference between the 2 products in question. The only noticeable differences are the measurements of Vitamin D and Magnesium. The RAW Probiotics Women has 500 IU of Vitamin D, and 8.4 mg of Magnesium. While the RAW Probiotics Women 50 & Wiser has 667 IU of Vitamin D and 14 mg of Magnesium. Sincerely, Kellie B.

The IU varies depending on the substance, but for Vitamin A it is 0.0003 milligrams. Since there are 200,000 iu in this bottle and 56 grams, I calculate 0.06 grams per bottle, or 0.1%

Yes, it is very important to take 4000-6000 IU of vit D daily based on what my naturopath says and other sources. This one only has 270 IU per serving. I take the 5000 IU Vit D softgels by NOW.

I'm not sure what the difference is between 1 and 2. Right now, I take 1 daily and if need be, I'll take 2-3 but usually 1 per day keeps me in pretty good shape. When I first started taking it, I would take 3 and wait about 24 hours and if nothing, I'd take another 1 and so on until I found out how many worked for me. My sister has gotten up to 9. I've gotten up to 5. Like I said though, I don't have to take that many now and 1 a day seems to keep me regular. :-) Hope this helps!

Here is some basic conversion based on info from wikipedia. For vitamin A, 1 IU is equivalent to 0.3 micrograms retinol. Therefore this one jar contains 200,000 IU equivalent to 0.06 g retinol in 56 g total weight, which is about 0.107% *Edited the calculation from comment from Greg.D.

Vitamin A there's 1000 Iu. Vitamin C is 200 mg. Vitamin E there's 60 IU Zinc there's 40 mg. Selemiun is 55 mcg. Copper is 2mg. Lutein there's 2mg. Hope that helps.

I just looked it up. 500 mgs. = 50,000 IU. Looks like you just add a couple of zeroes.

As far as I know, the petites are exactly like the regular Rainbow Light Prenatal One vitamins, the only difference is they are smaller pills than the one-a-day pills. You take three per day instead of the one.

You cannot just add the numbers on the label to get the answer to this question. The label lists only one part of the complex in IU. The others are listed in mg. These units are not equivalent. There are 4 tocopherol isomers (alpha, beta, gamma and delta) and 4 tocotrienol isomers (alpha, beta, gamma and delta) in natural vitamin E. The balance of alpha to beta to gamma to delta in each form depends on the source. The bottle label does not provide the source, therefore it cannot be calculated from the label information. This is a question for the manufacturer.

I take this because I take 5000 IU's of Vit D3 per day and in order for the calcium in your blood to actually go into your bones, you need 100 mcg of MK7 K2 per 1000 IU's of D3. This is critical for men because calcium floating around in the arteries is really not a good thing... This element is essential for preventing osteoporosis so don't leave it out!

I am a physician with a personal interest in Vitamin D research, here's the skinny: There is only one form of prescription vitamin D- ergocalciferol (D2) 50,000 IU. This product is cholecalciferol (D3) 50,000 IU and is not chemically identical. There is strong evidence, however, that the OTC form (D3) is superior to the Rx form (D2) in both absorption rates and sustained effect. In addition, the Rx form (D2) is not what the human body creates on it's own, it makes D3. While both will raise the total level of Vit-D-25-OH tested on vitamin D blood assays, only the OTC D3 form significantly raises the naturally formed isomer of D3. I know of no research that investigates whether elevated D2 levels have the same health benefits as are seen with elevated natural D3 levels. Ergocalciferol was grandfathered in as a drug by the FDA in 1940 when they started regulating medications, and has been used since out of habit. Most doctors are not well educated on this subject and prescribe the Rx form as it is the only formulation able to be prescribed, and because it is dogma. In short, this OTC form of cholecalciferol D3 is better absorbed, longer lasting, cheaper, more accessible, and a match to naturally produced human vitamin D analogues. It can be safely substituted for ergocalciferol D2 prescribed by your doctor.

just checked the jar... it says combined content of vitamins E, A and D is over 200,000 IU. but keep in mind this is for the entire jar which is 16 oz. For 1 oz jar it would be equal to 12,500 IU.

I am not aware of the product D2. I take the D3-50 which is a dose of 50,000 IU of vitamin D.

The recommended dosage is one teaspoon, which contains 4,000 IU of Vitamin A or 80% of daily needs if based on a 2,000 calorie diet. For Vitamin D, one teaspoon contains 400 IU.
