    Calcium

    With meals, split into 2 doses

    Calcium is the most abundant mineral in the human body, with roughly 99% stored in bones and teeth. It is obtained through dairy products, leafy greens, fortified foods, and supplements. While essential for skeletal integrity, its value as a standalone supplement for adults with adequate dietary intake is debated.

    Safety & Cautions

    Side Effects

    • Constipation
    • Bloating and gas
    • Kidney stones at high doses
    • Possible cardiovascular concerns with excessive supplementation
    Calcium supplements are generally well tolerated at recommended doses but should not exceed 2,500 mg per day from all sources combined. High-dose supplementation without adequate vitamin D and K2 may contribute to vascular calcification, so pairing with cofactors is advisable.
