  • Drug Interactions

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

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

    Vitamin K2, including the vitamin K2 in AlgaeCal Plus, may interfere with certain anticoagulant drugs and should be avoided unless otherwise directed by a physician.

    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) - 720mg

    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.

    Boron - 3mg

    This essential nutrient helps your bones get the calcium, magnesium, and vitamin D they need to stay healthy and strong. It also helps your body make collagen, the main protein that holds your bone together.

    Magnesium - 350mg (from l. superpositum and magnesium-oxide)

    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 C - 50mg

    Vitamin C helps your body fight the root cause of bone loss. A 17-year study found that a high intake of this vitamin reduced the likelihood of hip and non-vertebral fractures.

    Vitamin D3 - 40mcg (1600IU)

    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 serving of AlgaeCal Plus has a generous 1,600 IU of this bone-building vitamin.

    Vitamin K2-7 - 100mcg

    You need vitamin K2 because it collects calcium from your bloodstream and directs it into your bones - keeping them healthy and strong. You don't want calcium getting into your soft tissue - where it can cause heart attacks, strokes, and even Alzheimer's.

Why AlgaeCal Plus Works
Superior Plant-based Source
AlgaeCal Plus starts with a unique ocean algae.
Unlike rock-based calcium, AlgaeCal Plus' plant-based algae supplement naturally contains ALL the nutrients your bones need, in a whole-food form your body can more easily absorb.
13 Essential Minerals
Calcium alone is not enough
Calcium from rocks contains just calcium. Our marine algae is sustainably harvested, and naturally contains 13 essential nutrients necessary for building strong, healthy bones.
Plus Vitamins D3, K2, and C
The "Plus" in AlgaeCal Plus
We start with a superior source of calcium, then we add vitamins D3, K2-7, and C, plus additional boron and magnesium. These essential additions are the "Plus" in AlgaeCal Plus.
Gentle Digestion
More effective, yet easier to digest
Your body is meant to consume plants, not rocks. That's why AlgaeCal's algae-based supplement is more easily digested and absorbed. Better for you bones. Better for your body.

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 absorbs all the bone-building minerals from sea water in a whole-food source. So would you prefer to get your minerals from rocks, or plants? We eat plants every day, so your body recognizes the nutrients in AlgaeCal and puts them where they're needed: Your bones!
