Vitamin D3 Used to Boost Immune System as Suggested by a Growing Body of Evidence

Vista, California — Vitamin D has long been known to promote healthy bone growth. Now a growing body of research has revealed its role in boosting the body’s immune system as well. A 2011 study published in the Journal of Investigative Medicine found that “Vitamin D has important functions beyond those of calcium and bone homeostasis which include modulation of the innate and adaptive immune responses.”1

Additionally, a recent meta-analysis of scientific studies that examined the role of vitamin D supplements in preventing acute respiratory infection concluded that vitamin D “protected against acute respiratory tract infection overall.”2 A similar study cited by the New York Times found that taking a vitamin D supplement reduced respiratory infections in its participants by 40%.3 These are crucial findings, in light of the current health environment.

Vitamin D can be found in both D3 and D2 forms. The former, D3, is widely considered to be more bioavailable than its counterpart. In fact The Harvard School of Public Health recently reported on multiple studies that found “D3 supplements tended to raise blood concentrations of the vitamin more and sustained those levels longer than D2,” meaning it is more likely to enter the body’s circulatory system, thereby increasing its efficacy.4

Traditional D3 vitamins are made from lanolin, a wax secreted by sheep. However, there are alternatives, found in the plant-based supplements offered by Vegan Life Nutrition, which uses a Vitamin D3 that is derived from Lichen. Available in soft gels, chewable tablets, gummies and spray form, these Vegan D3 vitamins meet the strict standards of the UK Vegan Society.

The discovery of the role vitamin D plays in facilitating a healthy immune system coupled with the vitamin’s better-known benefits makes vitamin D3 a crucial supplement for individuals committed to maintaining optimal health.
