There’s a lot of conflicting information out there about the amount of Vitamin D3 someone should take. As it pertains to our Vitamin D3 product, we recommend following the Suggested Usage instructions on the bottle, which are to take one 5,000 IU Softgel every other day. However, some people may need more depending on your levels, which is why having your Vitamin D3 levels tested and consulting with a medical professional is extremely important.

IU stands for International Units, an internationally accepted method of quantifying the biological effect you can expect from a dose of fat-soluble vitamins. You can convert between micrograms or other metric units with IU, but each form of a given vitamin will have its own conversion factor.

For Vitamin D3, the conversion rate is 40 IUs/mcg. For example if you have 5,000 IUs of Vitamin D3, divide by the conversion rate to find the equivalent in mcg: 5000 IU ÷ 40 IU/mcg = 125 micrograms per Softgel

Our Vitamin D3 does not contain nor is it manufactured with yeast, wheat, gluten, soy, corn, milk, egg, fish, or shellfish ingredients. However, it is produced in a GMP facility that processes other ingredients that may contain these allergens.

The recommended dosage of our 5,000 I.U. Vitamin D3 is one Softgel Every 2 Days for Adults (i.e., 2,500 I.U. per day). Due to the high potency of our Vitamin D3 Softgels, we recommend that you consult with your medical professional for the ideal amount to give to your child.

For a quick reference, a 2011 Study on Vitamin D3 Published in The Journal of Clinical Endocrinology & Metabolism suggests the following dosages for children:

“2.6 We suggest that the maintenance tolerable upper limits (UL) of vitamin D, 

which is not to be exceeded without medical supervision, should be 1000 IU/d 

for infants up to 6 months, 1500 IU/d for infants from 6 months to 1 yr, at least 

2500 IU/d for children aged 1–3 yr, 3000 IU/d for children aged 4–8 yr, and 

4000 IU/d for everyone over 8 yr. However, higher levels of 2000 IU/d for 

children 0–1 yr, 4000 IU/d for children 1–18 yr, and 10,000 IU/d for children 

and adults 19 yr and older may be needed to correct vitamin D deficiency.”

Our Vitamin D3 is recommended for human consumption only.

If you are pregnant or nursing, we recommend consulting with your health care professional before use as a precautionary measure.

Notably, a 2017 Study Published in the journal Obstetrics and Gynecology International details that the risk of Preeclampsia in Pregnant Women is 2x Higher when not supplementing with Vitamin D3:

“The intended intervention (i.e., prescription of vitamin D) has a protective effect

against recurrent preeclampsia. Vitamin D supplementation therapy in pregnancy 

could help in reducing the incidence of gestational hypertension/preeclampsia”

There is a great deal of discussion on whether or not a person needs to take Vitamin K2 with Vitamin D3. In fact, there are many claims that K2 is necessary for the proper absorption of D3, but this is not accurate. There are no current, peer-reviewed studies showing the need / benefit of taking Vitamin K2 in the same supplement as D3. In fact, most individuals get plenty of K2 in their diet and supplementation is seemingly unnecessary.

For this reason, we have opted to offer a high-quality, absorbable Vitamin D3 on its own to allow our customers the choice of whether or not they want to add Vitamin K2 to their daily regiment.
