What is Vitamin D3?

Vitamin D3, also known as cholecalciferol, is a potent form of vitamin D that our bodies naturally produce when exposed to sunlight. It is the form of Vitamin D that is most beneficial to humans. Despite its name, vitamin D is actually a hormone. When ultraviolet B light hits our skin it produces a vitamin D precursor, which then undergoes two conversions in the liver and the kidneys before reaching its active form, Calcitriol. This active hormone regulates levels of calcium and phosphorous in the body and is thus vital to bone health. Due to the very limited amount of foods containing vitamin D (fatty fish, cod liver oil, egg yolks, fortified milk), most people rely on sunlight exposure as a source of the vitamin.

The amount of vitamin D available through sunlight exposure, however, is dependent on several factors including: sunscreen use, time of day, time of year, location, age, and skin pigmentation. Supplements can be a convenient source of vitamin D for those who struggle to obtain adequate amounts from their diet or sun exposure.

What are the benefits of Vitamin D3?

Vitamin D3 plays a critical role in bone health. It supports the growth and maintenance of bones by enabling the efficient absorption of Calcium in the small intestine.

Why take Vitamin D3 supplements?

Supplements serve as a convenient option for anyone looking to increase their vitamin D intake. Some populations whom supplements may be especially beneficial for include: people living in areas with little sun exposure, people who regularly wear sunscreen, people following a vegetarian or vegan diet, people with darker skin pigmentation, and people older in age.
