I started taking Activated Calcium over a year ago and my bone density improved!

Activated Calcium

I have been taking activated calcium for one month and so far it seems like a good product. I have had no issues.

One capsule does not equal 700 mg

Gina G.

I listen each week to the Nutritional Weight and Wellness podcast. It was because of a podcast that I learned about calcium and the different forms. I appreciate the fine information by the nutritionists and realized the calcium I had been taking was not the best form for absorption so I switched to this calcium from NutriKey. I greatly appreciate that these vitamins are third party tested and pharmaceutical grade. And customer service is excellent!!
