Vitamin D

While our bodies synthesize vitamin D when exposed to sunlight, many of us use sunscreen or avoid direct sun exposure, and for good reason. But this can impact vitamin D production. Our award-winning Vitamin D3 with Sea-Iodine™ helps ensure you get enough vitamin D, and also iodine, which is essential for thyroid health.

Vitamin E is a group of eight different antioxidant compounds found in plants. These compounds are some of the most researched and most important nutrients to include in your daily regimen. Vitamin E is divided into two categories, tocopherols and tocotrienols, each with their own set of health benefits.
