Highly Bioavailable Seaweed Calcium for Strong Bones

120 Vegetarian Capsules. Pure, ocean-derived calcium that your body can actually use. ClearCal delivers exceptional, plant-based calcium sourced from Maerl — a rare calcified red seaweed (Lithothamnium) harvested from the pristine coastal waters of southwest Ireland. Developed by Dr. Peter D’Adamo, this clean, cofactor-free formula provides superior absorption and bioavailability to support bone strength, healthy mineralization, and overall mineral balance — suitable for all blood types.

Why ClearCal Is Different

Premium Maerl Source: One of the purest natural calcium sources available, with very low levels of contaminants. Maerl naturally contains calcium carbonate plus trace amounts of magnesium, boron, zinc, and other essential nutrients.
Exceptional Bioavailability: Its unique structure and superior buffering capacity allow high absorption even with varying digestive pH levels across blood types. Studies on similar seaweed calcium show significantly better uptake than standard calcium carbonate.
No Added Cofactors: Pure calcium focus
100% vegetarian, allergen-free, and produced under strict GMP standards.
Suitable for All Blood Types
Provides highly absorbable calcium to support bone density, strength, and healthy skeletal maintenance — essential for long-term bone integrity.

Key Benefits

Superior Absorption: Maerl’s natural mineral matrix and excellent solubility promote efficient uptake, helping your body utilize calcium more effectively than many conventional sources.
Broad Nutritional Support: Naturally occurring trace minerals (magnesium, boron, zinc) contribute to bone metabolism, joint comfort, and overall wellness.
Daily Foundational Support : Ideal for anyone needing reliable calcium intake — especially those who don’t consume enough dairy or other calcium-rich foods.

Suggested Use

Take two (2) capsules twice daily with meals as a dietary supplement, or as directed by your healthcare practitioner. Servings: 60 servings per bottle (120 capsules).

For California Residents Prop 65 Warning

Our Perspective on This Warning

We are required to include this warning under California law. We test every batch of our Maerl seaweed calcium to ensure the lowest possible naturally occurring trace minerals. Lead levels are extremely low, typical of many ocean-derived minerals, and well within safety guidelines set by regulatory bodies worldwide, including the FDA. This warning is required under California law even for trace amounts well below levels of concern in most other countries. We remain committed to the highest standards of purity and bioavailability for all our products.
