Key item features

  • Collagen and calcium – When it comes to your bones, calcium and collagen are intimately connected. KoAct® is a special combo of chelated calcium and hydrolyzed collagen peptides. Together, they support optimal bone density and strength.
  • Bone cell support – There are polyphenol compounds in dried plum that support the activity of osteoblasts, the special cells that actually rebuild bone. This formula also has vitamin D3—an essential nutrient for bone health. 
  • Bone health minerals – Magnesium, silicon and boron are all part of bone mineralization (the process your body uses to make your bones stronger). Our boron is made with a calcium/carbohydrate complex that’s similar to what is found in fruits and veggies.
  • Ingredients matter – We use only pure, high-quality ingredients. The majority of our products are non-GMO and gluten-free—and a Certificate of Analysis is available for every one.
  • Live your healthiest life - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. That’s why so many of our nutritional formulas are designed using specific ingredients and amounts based on scientific studies.

Very effective

Since I started taking it last year, it immediately started strengthening my bones and my hip pain went away.

Bone Density Miracle

This supplement has miraculously improved my bone density. I have been using it for over 5 years and each time I've had a DEXA scan since, my numbers have been getting better and better. Highly recommend!! It's expensive but worth it!!!!

Strong bones

My bone scan shows my bones to be younger than my chronically age. I have taken bone strength even when it was called bone restore for ages. Do think this helps. [This review was collected as part of a promotion.]
