Produced from the sun
Vitamin D is found in our diet, but we 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. Regional factors that prevent people from getting sun exposure include cloud cover patterns, smog, and the angle with which the sun hits the earth. In cities north of 37 degrees latitude (imagine a line drawn between San Francisco and Richmond, VA), it’s hard for people to produce enough vitamin D from sun exposure, especially between the months of November and March.

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 2,000 IU of vitamin D saw a higher concentration of the immune cells responsible for strengthening our bodies’ natural defense system.*
