Produced from the sun
Vitamin D is found in certain foods, and our bodies also produce it through exposure to sunlight. However, a number of factors impact the ability for people to get necessary levels of vitamin D through sun exposure. Factors that prevent people from getting sun exposure include wearing sunblock, cloud cover patterns, smog, and the angle at which the sun hits the earth where you live.

Helps keep your immune system strong
Several placebo-controlled studies have shown that vitamin D can regulate the growth and function of immune cells, which are critical for a healthy immune and inflammatory response. In one study, participants who were given 50 mcg (2,000 IU) of vitamin D saw a higher concentration of the immune cells responsible for strengthening our bodies’ natural defense system.*
