Iuvenis Longevity Factor gives you a unique and powerful combination of all-natural nutrients to help boost blood flow and circulation, slow the effects of aging, and reduce the damaging effects of misplaced calcium in the body. It includes a special, fast-acting form of vitamin K2 called K2Vital Delta®. This patented form of K2 uses MK-7 the same ingredient in fermented foods that make up a big part of the Japanese diet. K2Vital Delta®’s role in arterial health is supported by its clinically-proven promotion of calcium metabolism in vascular structures. Plus, you get high-quality forms of vitamin D3, resveratrol, and quercetin in clinical doses to support your body’s healthy aging.
