Each drop contains 100 IU of Vitamin D: 4 drops provide 400 IU, 20 drops provide 2,000 IU. A full dropper full provides approximately 50 drops, or 5,000 IU.
CAOH® Power Vitamin D3 Liquid Advanced Formula supplies 400 IU of vitamin D3 (Cholecalciferol) per dose. This important vitamin is in a highly absorbable liquid form. Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. However, it is not readily abundant in food. As more people avoid sun exposure, Vitamin D supplementation becomes even more necessary to ensure an adequate supply.
