Patients with the highest levels of vitamin D have half the risk of dying compared to those with the lowest levels, according to the research.
A recent study published at Experimental Biology 2014 demonstrated the long-term efficacy of KoACT in reducing bone loss in post-menopausal women. The supplement, which combines a proprietary formulation of calcium and collagen, prevented whole body bone mineral density loss at twelve months compared to a control group.

Instead, genetic mutations compromising the skin's barrier function enabled survival at higher latitudes. High rates of filaggrin mutations in Northern European populations correlate with increased vitamin D levels.
