Annual Change in Bone Mineral Density (BMD)

AlgaeCal® is Shown to Increase Bone Density - Not Just Slow Bone Loss

What makes AlgaeCal® really unique is, together with vitamin D3, it has been shown to help increase bone mineral density (BMD) starting in as little as six months.

This was demonstrated in a study published in the International Journal of Medicine. The study included 36 women with an average age of 69.5.

For a full year, these women were asked to take a daily supplement containing 750mg of calcium from AlgaeCal® and 1,000 IU (25mcg) of vitamin

On average, the study participants increased their bone mineral density by 1.30% in one year.


AlgaeCal® is USDA certified organic and harvested from a marine plant off the coastline of South America. It naturally provides calcium in a form that, unlike rock based supplements, is easy on your stomach and easier for the body to use.

AlgaeCal® is effective using just 750mg a day, compared to most calcium supplements that require 1,000mg or more per day.



Vitamin D is necessary for calcium to be absorbed efficiently from your stomach to your bloodstream. Once in the bloodstream, vitamin D can work with calcium and other minerals to help build and maintain bone.

TrueOsteo™ contains 1,000 IU of Vitashine® a plant derived (from lichen) vitamin D3 suitable for vegetarians and vegans.


Recent research has shown vitamin K2 is a very important nutrient for keeping calcium in your bones and out of your arteries, and can help strengthen bones. Unfortunately, other research shows that as much as 97% of the Western population is deficient in vitamin K2 through diet alone.

Unlike many synthetic K2 supplements the MenaQ7® in TrueOsteo™ is made from a natural source, chick peas.
