🧪 Formulation Notes

1,000 mg of Calcium per serving Calcium citrate is a form of calcium that is more soluble and better absorbed by the body than other forms of calcium. Research suggests that people who experience low levels of HCl in the stomach may absorb more calcium from calcium citrate than from calcium carbonate. Calcium citrate can help support and maintain healthy skeletal system, especially during the menopausal years when bone loss increases.

Suitable for vegetarians.

Contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.
