Benefits at a Glance

  • Optimizes bone strength and flexibility

Enhanced bone health

Consuming diets high in collagen to improve bone health dates back to ancient cultures. But now this exciting formulation with KoAct®, makes achieving that goal simpler by helping maintain bone strength and mineral density.1

This remarkable compound allows for greater strength and flexibility, so your bones can absorb impact, reducing the risk of age-related injuries. Bamboo and dried plum extracts offer additional bone-protective minerals and polyphenols2-8 to round out this robust formula.

To help optimize bone strength and flexibility, Bone Strength Formula with KoAct® uses these ingredients:

Vitamin D3

This critical nutrient facilitates absorption of calcium into the bloodstream and regulates how much of it enters and leaves bone tissue. D3 is also a vital co-factor in bone mineralization through absorption of calcium and phosphorus.


KoAct® is a unique patented formula. It combines hydrolyzed collagen peptides (type I collagen) with calcium which has been chelated — a chemical process that bonds molecules to metal ions to create compounds which are more nutritionally viable and easier for the body to absorb.

KoAct® was designed to enhance collagen support and turnover while supporting optimal bone mineral density and strength.


This is a critical component of our skeleton, with 50%-60% of all magnesium in the body found in bone. It also positively influences the bone mineral matrix and its ability to metabolize minerals needed for repair and rebuilding.


Plays an important role in bone formation through the synthesis and/or stabilization of collagen.

Dried Plum

Supports osteoblast (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 is an essential nutrient for optimal calcium metabolism and healthy bones and joints.

Bone Strength Formula with KoAct® can be part of a comprehensive nutritional program in conjunction with proper resistance exercise. Life Extension offers several mineral formulas that may complement Bone Strength Formula with KoAct® to ensure optimal bone health.
