Vitamin D3 5,000 by Seeking Health is a pure and potent vitamin D3 supplement in a vegetarian capsule that provides 125 mcg (5,000 IU) of cholecalciferol. Many people do not get sufficient vitamin D3 in their diet, and the synthetic vitamin D2 that is often added to dairy products is considered an inferior form of this vital nutrient. Vitamin D3 occurs naturally in fatty fish, cod liver oil, egg yolks, and beef liver. Vitamin D3 5,000 contains cholecalciferol derived from cholesterol in sheep's wool, making it suitable for vegetarians.
Vitamin D is essential for the functioning of many important systems in the body, and recent research has suggested that we may need more vitamin D than previously thought for optimal immune function and long-term health. In some climates, people may be able to produce adequate vitamin D3 from sunlight, but in cooler climates with longer winters, vitamin D deficiency may be more common.
Vitamin D is required for optimal absorption of minerals including calcium, making it an important nutrient for supporting healthy bones and structural health. It may also play a role in supporting immune health and cellular integrity.
