Your skin produces vitamin D when in direct sunlight or indoor tanning devices, but that’s not an ideal solution for obvious reasons. Choose a potent vitamin D3 supplement from Life Extension instead.

Individuals consuming more than 50 mcg (2,000) IU/day of vitamin D (from diet and supplements) should periodically obtain a serum 25-hydroxy vitamin D measurement. Do not exceed 10,000 IU per day unless recommended by your doctor. Vitamin D supplementation is not recommended for individuals with high blood calcium levels.• Keep out of reach of children. • Do not exceed recommended dose. • Do not purchase if outer seal is broken or damaged. • When using nutritional supplements, please consult with your physician if you are undergoing treatment for a medical condition or if you are pregnant or lactating. Contains tree nuts (coconut).Store tightly closed in a cool, dry place.
