Thorne Calcium-Magnesium Malate, 240 Capsules

Thorne's Calcium-Magnesium Malate is a mineral supplement formulated to support bone and muscle health, with a focus on providing a balanced 1:1 ratio of calcium to magnesium. It uses malate forms of both minerals, which the manufacturer notes are chosen for optimal absorption. The product is intended to help maintain normal heart rhythm and promote relaxation in muscle cells, based on the interplay between these minerals.

This supplement distinguishes itself by offering a 1:1 calcium-to-magnesium ratio, a formulation that some experts recommend over more common 2:1 ratios. Thorne emphasizes third-party testing to verify label accuracy and ensure the absence of contaminants like heavy metals or pesticides. It comes in a 240-capsule bottle, with each capsule containing 100 mg of calcium and 100 mg of magnesium, and is manufactured in the USA using domestic and imported ingredients.
