It’s estimated that about 1 billion people worldwide have low levels of vitamin D. A 2011 study shows that 41.6% of adults in the U.S. are deficient in this essential vitamin.

When you expose your skin to sunlight, a reaction takes place, which results in the production of vitamin D. Vitamin D synthesis is a key to immune health and other benefits, but getting enough is not always easy. Season, time of day, cloud cover, smog, skin melanin content, age, concern about UV radiation, even sunscreen are all reasons you may not be getting all the D3 you need.

Just one chew a day gives you our highest potency 5,000 IUs of Vitamin D3.
