About AlgaeCal®

AlgaeCal® is a plant-based, naturally sourced calcium derived from Lithothamnion superpositum, a unique marine algae rich in bioavailable minerals that support lifelong bone strength. Unlike conventional calcium supplements made from rock or limestone, AlgaeCal® provides a food-source calcium complex containing magnesium and trace minerals essential for healthy bone formation. Sustainably hand-harvested from pristine South American coastlines, this calcium is simply washed, sun-dried, and milled — preserving its natural nutrient profile without harsh processing.

At Coal Harbour Pharmacy, our curated AlgaeCal® selection includes clinically researched formulas designed to maintain bone density, support healthy aging, and complement an active lifestyle. With USDA-certified organic sourcing and environmentally responsible harvesting, AlgaeCal® offers a clean, effective alternative to traditional calcium supplements.
