Why Choose LithoLife’s Organic Algae Calcium?

The source of this ingredient is wild Lithothamnion calcareum, a natural calcareous alga, sustainably collected in the Northeast coastal region of Brazil and then processed in a totally chemical-free manner.  

Daily supplementation of only 3.4g of Lithothamnion covers 97.8% and 28.5% of the RDI of calcium and magnesium, respectively

Also, Lithothamnium is a plant source of over 70 essential minerals—these micronutrients facilitate calcium absorption, contributing to the high bioavailability of 86.7%.

Here are the other reasons why our clients chose LithoLife’s organic algae calcium:

1. Non-GMO; Halal, Kosher, and USDA organic certified

2. 100% natural and vegan, free from additives and allergens such as lactose or gluten
3. The algae are dried, milled then packaged without bleaching, which complies with international safety standards.

Algae Calcium: Nature’s Best Answer to Calcium Supplementation

Lithothamnion calcareum is a plant source of calcium that features high mineral content and easy absorption by the human body. When comparing Lithothamnion to other calcium sources, we found it stands out as a preferable option with the highest bioavailability of all:

3 Advantages of Algae Calcium Supplementation

As discussed above, the bioavailability of Lithothamnion can reach 86.7%, which is 1.2 times higher than calcium carbonate. Here are the main reasons why: 

1. High porosity (>40%) provides a larger acting surface and facilitates absorption.

2. The Fine powder form contributes to faster absorption and prevents bloating.

3. Ca, Mg, and other ocean micronutrients are bound in the unique honeycomb structure.
