Vitamin D

Vitamin D is produced by the skin through the absorption of the suns UVB rays. In Winnipeg, from October to April, due to the sun’s distance from the earth, Vitamin D synthesis basically stops. During the summer months, sunscreen as low as SPF 8 slows Vitamin D synthesis by 95%, therefore greatly inhibiting our ability to utilize the vitamin and achieve the daily-recommended amount of 400-1000 IU/day. Please consult with your doctor because certain individuals that are deficient may require amounts higher than 2000IU/day.
