Overview
ALGAECAL's Bone Builder Pack combines 720mg of plant-based calcium with strontium, 1600 IU of vitamin D3, vitamin K2, magnesium, and 16 total nutrients in 180 capsules sized as a 1-month supply. That works out to about six capsules a day.
Rather than a single calcium tablet, this is a multi-ingredient stack, which is why the daily count runs to roughly six capsules instead of the one or two typical of plain calcium supplements. The calcium itself is plant-sourced rather than the calcium carbonate used in many cheaper products.
- 720mg plant-based calcium
- 1600 IU vitamin D3 plus vitamin K2
- 180 capsules, a 1-month supply
- 16 nutrients total for bone health
Who it's for
Fits someone who wants a comprehensive bone health regimen combining calcium, D3, K2, and magnesium in one pack and doesn't mind a higher daily capsule count. Not a fit for anyone who wants a simple one or two pill daily calcium supplement.
Strengths and trade-offs
Drawn from this product's published specifications.
- Plant-based calcium source rather than calcium carbonate
- Combines calcium, D3, K2, magnesium, and strontium
- 16 total nutrients in one pack
- Roughly six capsules per day, a higher daily pill count
- 180 count covers only 1 month
Performance notes
720mg of plant-based calcium plus 1600 IU of vitamin D3 with added K2 and magnesium reflects a full bone-support stack rather than calcium alone, and the 180-capsule, 1-month sizing means roughly six capsules make up a daily dose.
