  • Drug Interactions

    Some medications and supplements require separation from AlgaeCal to limit any potential interactions. For example, thyroid medication, antacids, and certain antibiotics should be taken at least 4 hours from AlgaeCal. Iron supplements also should be separated correctly.

    If you take a standalone iron supplement, please take it 2 hours from AlgaeCal to avoid decreased absorption. If your iron comes from a multivitamin, you do not need to separate it from AlgaeCal.

    For general guidelines about how to take AlgaeCal, please reach out to our Bone Health Consultants at [email protected] or by calling 1-800-820-0184. Always check with your doctor for details about possible interactions between AlgaeCal products and your medications.

    What's Inside?

    Calcium from AlgaeCal (l. superpositum) - 750mg

    AlgaeCal is a unique calcium that contains all 13 essential bone-building minerals. Studies show these plant-based nutrients can stop bone loss – and even increase your bone density.

    Magnesium - 65mg (from l. superpositum)

    If you want better bones, then you need more magnesium. Clinical studies show people with healthy magnesium levels have better bone density than their magnesium-deficient counterparts.

    Vitamin D3 - 25mcg (1000IU)

    Vitamin D is vital for your bone health. Without this essential nutrient, your body can't absorb calcium, and that's bad news for your bones. But don't worry – every daily dose of AlgaeCal Basic has a generous 1,000 IU of this bone-building vitamin.

The Smarter Formula

Whole-Food Nutrition Means Gentle Digestion

Traditional calcium supplements are made from milled limestone or marble, making them challenging to digest and absorb. But AlgaeCal's marine algae draws all the bone-building minerals from sea water and absorbs them for it's metabolic needs. That allows your body to properly assimilate the minerals and put them where they're needed: Your bones!
