Advanced Info

Typically known as the “sunshine vitamin” because ultraviolet rays on the skin produce it, vitamin D can also be obtained through supplementation. Natural Factors Vitamin D3 Drops is naturally derived from sheep wool lanolin, and is in the cholecalciferol form, which is the safer, natural, and more biologically active form of vitamin D.

Vitamin D plays a crucial role in bone growth and renewal as it stimulates the absorption of calcium. It also reduces calcium excretion and facilitates calcium incorporation into the bones, reducing the risk of developing osteoporosis or soft, brittle bones. Because of its role in calcium absorption, it is also important for the maintenance of healthy teeth.

Supplementation with vitamin D is especially important for those who live in the northern hemisphere, with long, dark, northern winters. It is especially important during the winter season as there is limited sunlight, and therefore the body isn’t able to produce its own vitamin D sufficiently.

Liquid Vitamin D3 1000 IU from Natural Factors contains 95 % organic ingredients. The vitamin D3 is suspended in certified organic extra-virgin olive oil, organic flaxseed oil, and vitamin E, and the recommended dose is only 1 drop per day.
