Super-Nutrient For Support of Bone Density, Cardiovascular Health, and Immune Support


The more researchers study Vitamin D, the more they discover about this unique substance’s health benefits. Vitamin D, the “sunshine vitamin,” isn’t actually a vitamin at all but a fat-soluble hormone, and the body produces it mostly by synthesizing it out of exposure to sunlight. (It’s also available through diet from a handful of food sources like oily fish, egg yolks and some mushrooms).

Herein lies the problem. Most of us spend too much time indoors and even when we do venture out, we slather on plenty of sunblock. That’s good for avoiding skin cancer, but bad for a whole host of reasons.

Vitamin D is an essential catalyst for facilitating calcium uptake into bones to maintain bone density and strength. There is also a significant amount of research linking low levels of Vitamin D with decreased testosterone levels in men. Deficits in Vitamin D can also lead to early onset of fatigue because without it, the mitochondria in muscle fibers cannot adequately generate the energy needed for efficient muscle contraction.

Most recently, researchers are discovering a link between Vitamin D and immune function support. In a study published in The American Journal Of Nutrition provided evidence that a therapeutic dose of vitamin D resulted in a statistically significant (42%) decrease in the incidence of influenza infection (1). Another study, published in the journal Science found that Vitamin D may play an important part in the innate antimicrobial response (2).

ProSource’s Vitamin D product has been sourced from the highest-quality Vitamin D3 in the clinically effective, maximally bioavailable cholecalciferol form for optimum potency and efficacy. The Vitamin D3 in ProSource Vitamin D3 has been combined with a synergistically viable dosage of Vitamin K, which is another fat-soluble substance that works in tandem with Vitamin D3 to enhance calcium uptake and utilization to help maintain bone density. Vitamin K also supports cardiovascular health by helping to activate a key circulatory protein that inhibits blood vessel calcification.
