Vitamin D

Vitamin D, the sunshine vitamin, is produced by the skin when it is exposed to sunlight. Although direct sunlight exposure is a great source of vitamin D, due to the use of sunscreen, seasonal changes, geography, and lifestyle, many individuals don’t get enough sun, so they can be prone to having a low level of vitamin D. Therefore, finding the best vitamin D supplement can provide great health benefits.* Thorne’s Vitamin D Liquid for adults and children makes supplementation easy.
