Our assessment

For calcium, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high calcium intakes may carry risks that outweigh benefits for some individuals.
How it works

Our recommendation
Our recommendation: If you are taking this product for bone health, understand that the calcium content is the only ingredient with supporting data from the provided sources.
