Vitamin D3 400 IU (10mcg) 100 capsules

What is Pure Nutrition Vitamin D3?

Pure Nutrition Vitamin D3 is a highly bioavailable form of vitamin D3 (cholecalciferol), containing 400 IU in each capsule (dose). Vitamin D3 is a trace mineral with a wide range of functions in the body, such as regulating stress levels, supporting bone, skin and heart health, and regulating the immune system1.

Most of the vitamin D3 we get comes from direct exposure to sunlight, and spending significant amounts of time indoors can slowly deplete the body's vitamin D3 stores. Supplementing with vitamin D3 helps provide the body with the necessary daily dose.

Benefits of taking Pure Nutrition Vitamin D3

“Vitamin D” is a term that collectively refers to a group of five fat-soluble vitamins. Many people know vitamin D as the “sunshine vitamin” because our bodies produce it naturally through exposure to ultraviolet rays from the sun. Vitamin D is an extremely important micronutrient, with research showing that among the vitamins in the group, vitamin D3 (cholecalciferol) is the most crucial form for human health. 2

Since we naturally produce vitamin D transdermally (through the skin) through exposure to sunlight, its oral intake must necessarily be in the form of vitamin D3 – this is the most bioavailable form in capsules that is best absorbed by the body. 3

Vitamin D3 is structurally similar to cholesterol, a precursor to steroid hormones in the body. There are various enzymes in the liver and kidneys that convert vitamin D3 to hydroxylated derivatives, specifically calcitriol, the most biologically active form of vitamin D. The rate of conversion of calcitriol is limited by the availability of vitamin D3, which the body readily stores in case of need. For this reason, it is best to take vitamin D3 rather than calcitriol.

Biologically active vitamin D performs multiple roles in the body, specifically being extremely important for the proper absorption of the minerals calcium, iron, magnesium, phosphate and zinc. Calcitriol regulates bone growth and regeneration, as well as immune, cardiac and neuromuscular functions.

Due to an increasingly sedentary and closed lifestyle, vitamin D deficiency is constantly increasing among the population. It can lead to numerous health problems such as:

• Rickets;


• Fanconi syndrome;


• Autoimmune diseases;


• Non-alcoholic fatty liver disease;


• Osteoporosis.

Given the importance of vitamin D for the functioning of the human body and the increasing risk of deficiency, taking Pure Nutrition Vitamin D3 with a highly effective concentration of 400 IU per dose is recommended. The benefits of taking vitamin D3 include:

• Supporting cardiovascular function;


• Better mood and stress management;


• Improving immune defense;


• Strengthening bones.
