The use of high-collagen diets to improve bone health dates back to ancient cultures. Life Extension brings you this exciting formulation with KoAct®, a patented combination of calcium and collagen for optimal bone health. KoAct® helps to maintain bone strength and mineral density, allowing for greater strength and flexibility and reducing the risk of age-related injuries. Additional plant extracts from bamboo and dried plum have been added for their bone-protective minerals and polyphenols.

Bone Strength Formula with KoAct contains the following ingredients:

  • Vitamin D3 -  that 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 mineralisation through the absorption of calcium and phosphorus. 
  • Calcium - KoAct® is a unique patented chelated compound of calcium and hydrolysed 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 skeleton, with 50-60% of body magnesium found in bone; positively influences the bone mineral matrix and its ability to metabolise minerals, needed for repair and rebuilding. 
  • Silicon - that plays an important role in bone formation through the synthesis and/or stabilisation of collagen. 
  • Dried Plum - supports osteoblast (bone building cells) activity and function by up regulating cell - signalling 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 oestrogen and testosterone. 

For extra bone support, your medical professional can explain how Bone Strength Formula with KoAct® can be part of a comprehensive nutritional program in conjunction with exercise. Life Extension offers many mineral formulas that may complement Bone Strength Formula with KoAct® for optimal mineral intake.
