Formulation Notes

Life Extension brings you this exciting formulation with KoAct(R), a patented chelated form of calcium and collagen designed to maintain optimal bone health.

Additional plant extracts from bamboo and dried plum have also been added for bone-protective minerals and polyphenols.2-8

Bone Strength Formula with KoAct(R) contains the following ingredients: Vitamin D3 ~ Facilitates absorption of calcium into the bloodstream. ~ Regulates how much calcium enters and leaves bone tissue. ~ Helps regulate healthy cell division and differentiation. ~ Functions as a vital co-factor in bone mineralization through the absorption of calcium and phosphorus. Calcium ~ KoAct(R) is a unique patented chelated compound of calcium and hydrolyzed collagen peptides (type I collagen) designed to enhance collagen support and turnover while supporting optimal bone mineral density and strength. Magnesium ~ A critical component of our skeletin, with 50-60% of totally body magnesium found in bone ~ Positively influences the bone mineral matrix and its ability to metabolize minerals needed for repair and rebuilding. Silicon ~ Plays an important role in bone formation through the synthesis and/or stabilization of collagen. Dried Plu ~ Supports osteoblas (bone building cells) activity and function by upregulating cell-signaling compounds (Runx2, Osterix and IGF-1) and enhancing expression of an enzyme (lysyl oxidase) that is involved in collagen cross-linking. Boron ~ Impacts steroid hormone metabolism - affecting the levels of estrogens and testosterone.
