Overview
ALGAECAL's formula builds calcium from organic red algae and stacks it with vitamin K2 MK7 (100mg), vitamin D3 (1600 IU), magnesium (350mg) and trace minerals in 120 plant-based veggie capsules.
This goes beyond a plain calcium pill by combining nutrients that work in sequence for bone density and strength, rather than relying on calcium alone. Plant-based sourcing and veggie capsules make it usable for plant-based diets.
- Organic red algae calcium
- Vitamin K2 MK7 100mg
- Vitamin D3 1600 IU
- Magnesium 350mg, 120 veggie caps
Who it's for
Suits buyers who want a multi-nutrient bone density formula in one capsule instead of assembling calcium, D3, K2 and magnesium separately. Not for anyone who wants single-ingredient calcium or a lower-dose D3.
Pros and cons
- Combines calcium, D3, K2 and magnesium
- Plant-based sourcing in veggie capsules
- Marketed for bone density and strength
- More active ingredients to track for interactions with other supplements
- Higher combined dosing than a plain calcium pill
Performance notes
The ingredients play distinct roles: D3 helps the body absorb calcium, K2 MK7 helps direct that calcium toward bone rather than soft tissue, and magnesium acts as a cofactor for both, a layered approach different from a calcium-only pill.
