What is Pure Nutrition Vitamin D3?
Pure Nutrition Vitamin D3 is a highly bioavailable form of Vitamin D3 (cholecalciferol) providing 400 IU per capsule (serving). Vitamin D is a micronutrient with rather ubiquitous actions in the body, such as supporting stress levels, bone health, skin health, heart health, and immune regulation.1
Much of the Vitamin D we obtain comes from direct exposure to sunlight, thus spending a significant amount of time indoors (and away from sunlight) can slowly deplete the availability of vitamin D in the body. Thus, supplementing with Pure Nutrition Vitamin D3 can help you meet your daily vitamin D needs.
Pure Nutrition Vitamin D3 Benefits
“Vitamin D” is a term that collectively refers to a group of five fat-soluble vitamins that are classified as secosteroids. Many people think of vitamin D as the “sun vitamin” since our body naturally produces vitamin D upon exposure to ultraviolet rays from the sun. Naturally, vitamin D is a highly important micronutrient, with research suggesting that vitamin D3 (cholecalciferol) is the most crucial form in humans.2
Since we produce much of our natural vitamin D transdermally (through the skin) via sunlight exposure, it is imperative that oral supplementation of vitamin D comes in the form of vitamin D3; this is most bioavailable form of vitamin D in capsule form, maximizing its absorption into the body.3
Vitamin D3 is structurally similar to cholesterol - the precursor to steroid hormones in the body. The body has various enzymes in the liver and kidneys that convert vitamin D3 to hydroxylated derivatives, notably calcitriol - the most biologically active form of vitamin D. The rate of calcitriol conversion is limited by the availability of vitamin D3, which the body readily stores as needed. As such, it’s best to supplement with vitamin D3 as opposed to calcitriol.
Biologically active vitamin D performs a multitude of roles in the body, and is particularly crucial for proper absorption of the minerals calcium, iron, magnesium, phosphate and zinc. Calcitriol also regulates bone growth and regeneration, as well as immune, cardiac, and neuromuscular functions.
Vitamin D deficiency is increasing across the population due to our increasingly sedentary, indoor-based lifestyles. Not getting enough vitamin D can lead to a host of health issues, including:4,5
- Rickets
- Fanconi syndrome
- Autoimmune diseases
- Non-alcoholic fatty liver disease
- Osteoporosis
Given the importance of Vitamin D in the body and the growing risk of deficiency, supplementing with Pure Nutrition Vitamin D3 contains a high-potency 400 IU dose in every capsule. Pertinent benefits of Vitamin D3 supplementation include:6,7
- Promotes cardiovascular function
- Supports Healthy Mood and Manage Stress Levels
