AlgaeCal

AlgaeCal is a direct-to-consumer nutraceutical and dietary supplement company specializing in bone health products derived from a proprietary marine algae source, Lithothamnion superpositum (AlgaeCal® M. Superpositum). The company is best known for its flagship product, AlgaeCal Plus, which it markets as the only calcium supplement in the world clinically supported to increase bone density — a claim backed by multiple human clinical studies. Unlike conventional calcium carbonate supplements, AlgaeCal's calcium is plant-based and harvested from a specific species of South American red algae, delivering a naturally occurring matrix of bone-supporting minerals including magnesium, potassium, boron, silicon, phosphorus, strontium, zinc, copper, manganese, and selenium.

The company's core product line is anchored around its 'Bone Builder' system, which pairs AlgaeCal Plus with Strontium Boost, a strontium citrate supplement designed to accelerate the bone-building process. AlgaeCal differentiates itself in the market through its industry-unusual 'Stronger Bones for Life Guarantee,' which promises measurable bone density improvements as verified by DEXA scan within six months of starting the program, or a full refund of all product purchases between scans.

Beyond its bone-density core, AlgaeCal has expanded its product portfolio to include AlgaeCal Collagen, which features four patented collagen peptide forms — FORTIBONE®, FORTIGEL®, VERISOL®, and UC-II® standardized chicken cartilage — supported by over 25 clinical studies targeting bone density, joint comfort, and reduction of skin wrinkles. Additional offerings include AlgaeCal Restore, an anti-inflammatory joint comfort supplement; Magnesium Relax, a magnesium-based sleep and nervous system support product; a fat-soluble vitamin D3 balance supplement formulated with vitamins A, D, E, and K; and an Omega-3/Curcumin/Astaxanthin triple-antioxidant product for inflammatory response support.

The company also offers at-home diagnostic test kits, including Vitamin D and Omega-3 Blood Spot Tests, enabling customers to monitor their nutritional status conveniently. AlgaeCal employs vegetarian capsule formulations using vegetable cellulose, and its products are positioned within the premium, clinically substantiated segment of the bone health and women's wellness supplement market. The primary target demographic is adults — particularly postmenopausal women — concerned about osteoporosis, osteopenia, and age-related bone loss. AlgaeCal sells direct-to-consumer via its website and supports customers with educational tools such as a Bone Health Quiz.
