Overview
Plant-based calcium supplement delivering 750mg organic calcium with 1000 IU vitamin D3 and 13 minerals, 90 vegetable capsules, gluten free.
ALGAECAL sources its calcium from algae rather than rock-based minerals, marketed as plant-based, and pairs it with vitamin D3 and a spread of 13 minerals aimed at bone strength and density rather than calcium in isolation.
- 750mg organic calcium
- 1000 IU vitamin D3
- 13 minerals included
- 90 veggie capsules
Who it's for
Adults focused on bone health who want a plant-sourced calcium with D3 and added trace minerals. Not for anyone who wants an isolated calcium supplement without extras.
