Vytamin D3 1000


VYTAMIN D3 1000 is a highly bioavailable form of vitamin D3 (cholecalcif-erol) providing 1000 IU per softgel. Vitamin D is a micronutrient with rather ubiquitous actions in the body. Examples of vitamin D’s myriad functions in the body include: supporting stress levels, bone health, skin health, heart health, and immune function.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 lead to low levels of vitamin D in the body. Thus, supplementation with VYTAMIN D3 1000 can help ensure users obtain adequate amounts of this key micronutrient.


How VYTAMIN D3 1000 Works

Vitamin D is a term that refers to a group of five fat-soluble vitamins that are classified as secosteroids, with research suggesting vitamin D3 (cholecalciferol) as being the most important 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 come in the form of D3; this is the most bioavailable form of vitamin D in a softgel, maximizing its absorption into the body. 3

Technically speaking, vitamin D3 is structurally similar to cholesterol, and is converted via the liver and kidneys to its active form calcitriol. Calcitriol goes on to perform 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 supports and promotes bone growth and regeneration, as well as immune, cardiac, and neuromuscular functions.

It is crucial to obtain adequate amounts of vitamin D on a daily basis, as deficiency can lead to a host of health issues, including, but not limited to: rickets, fanconi syndrome, autoimmune diseases, non-alcoholic fatty liver disease, and osteoporosis.4,5

VYTAMIN D3 1000 Supplementation

Given the importance of adequate vitamin D levels in the body and many people’s lack of exposure to direct sunlight, VYTAMIN D3 1000 supplementation can help users in a variety of ways. The most relevant research-backed  benefits derived from consumption of vitamin D3 include: 6,7

  • Supports cardiovascular function
  • Supports healthy mood and stress levels
  • Supports bone and skin tissues
  • Supports immune function
