Vitamin D3 can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight. But, due to the winter season, weather conditions, and sun screen usage, the body’s ability to produce optimal vitamin D levels may be inhibited. These factors point to the value of taking a daily vitamin D supplement.
Vitamin D has long provided significant support for healthy bone density. However, scientists have also validated the critical role that vitamin D plays in regulating healthy cell division and differentiation, and its profound effects on human immunity. These findings link a deficiency of vitamin D to a host of common age-related problems.
The current RDA is only 600 IU. As a result of evidence of widespread vitamin D deficiency, prominent nutritional scientists are calling on Americans to increase their vitamin D intake to 1,000 IU per day and higher. Life Extension suggests that healthy adults supplement each day with at least 2,000 IU of vitamin D. Elderly adults may benefit from higher doses. The objective of taking a vitamin D supplement is to achieve an optimal 25-hydroxy vitamin D blood level of 50 ng/mL (or higher).
Vitamin D in the amount of 2,000 IU is contained in the multinutrient Life Extension Mix and the multivitamin Two-Per-Day Tablets. A vitamin D blood test can help you determine the additional amount of vitamin D you may need to supplement to achieve an optimal level.
Natural mint flavor has been added to Life Extension's Liquid Vitamin D3 for improved palatability.
Read the entire label and follow the directions carefully prior to use.

Caution: Individuals consuming more than 2,000 IU/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement.

iHerb Customer Reviews
I tend to have chronic immune system problems. I had been taking 50000 ius of D3 and had a blood level test that said my Vit. D level was good. However, I'd had a chronic, mild sore throat for the two months at the time I began taking this emulsified D3. Could be coincidence, but the sore throat stopped after taking this product for three days. I might add that I have celiac disease and hashimotos hypothryoid, which can make absorption of nutrients difficult. I think this product did the trick

I had 2 different Dr.'s recommend this brand name and was told drops are absorbed quicker and more effectively. I am sold.
Easy to use Vitamin D

This product was originally prescribed by my Doctor. Very easy to dose, good tasting and economical. Great to be able to buy and have shipped to Canada.
I normalized my serum vit D level via this product
Posted by Reviewer3168863 on Jul 11, 2013
I have fair skin, so it is difficult for my body to make enough endogenous vit D without risky sunburn or skin cancer. So I tend to cover up while working/recreating outdoors, resulting in an abnormally (unhealthfully) low serum vit D level . (I annually get my blood tested for vit D.) Daily dosing of 4 drops sublingually (and holding it there for 5 mins) normalized my vit D level. Moreover, continued dosing that way has inexplicably stabilized my vit D level at about the center of the normal range. One would have expected my level to instead have kept climbing above the normal range.
