In a 3-year randomized controlled study, vitamin D3 and calcium supplementation promoted bone strength and reduced risk of falling in women aged 65 or older. Vitamin D3 supplements were shown to support hip and non-vertebral bone health in a meta-analysis of twelve double-blind randomized controlled trials of 20,000 people. Vitamin D is essential for healthy calcium metabolism. It promotes intestinal calcium and phosphorus uptake and can reduce urinary calcium excretion. Population groups with greater direct sunlight exposure or more vitamin D3 exposure, were found to have stronger immune function than those with restricted sunlight exposure. Vitamin D3 receptors are known to exist on most immune cells and play a role in maintaining healthy immune cell maturity, differentiation and integration. Research indicates optimal serum levels of vitamin D3 may be important in maintaining the best health of the cells of the breasts, lungs, colon, esophagus, stomach, pancreas, bladder, prostate, uterus, ovaries and kidneys. Research indicates vitamin D may promote neural health by supporting healthy nerve conduction potential, antioxidant defense and neuronal calcium regulation. High circulating blood levels of end-chain vitamin D3, 25- hydroxyvitamin D, were associated with nerve and myelin health in a study of 7 million U.S. military personnel, published in JANA, 2006.
Quantum D3 Serum is a reliable, rich, live source of the healthiest natural vitamin D3 that is free of toxic tagalongs. Studies propose ideal vitamin D3 intake should be 2000 IU/day to support many body systems including healthy bone, nerves, heart, brain, lung, esophagus, breasts, colon, stomach, pancreas, prostate, uterus and ovaries kidneys. Higher levels of vitamin D were correlated with healthy mood and mental function in two studies of more than 300 elderly people. Additionally, we now know that vitamin D receptors and vitamin D hydroxylation pathways exist in areas of the brain responsible for memory and cognition. Healthy blood vessel relaxation and blood flow are associated with ideal levels of vitamin D3. Healthy inflammatory response, antioxidant defense and cytokine production are associated with optimal blood levels of vitamin D as well.
