Vitamin D
Vitamin D is made in the skin from sunlight, and during the dark half of the year in the Nordics it is hard to get enough. Vitamin D contributes to normal immune function, to normal absorption of calcium and to the maintenance of normal bones. GAAM Vitamin D provides 100 µg (4,000 IU) vitamin D3 per tablet, and GAAM Vegan D3 + K2 combines D3 with vitamin K2 in vegan capsules.
One tablet a day, ideally with a meal that contains fat.
