Overview

Carlyle's calcium supplement pairs 1200mg of calcium with vitamin D3 in a 300-softgel bottle, unflavored and formulated non-GMO and gluten free.

Pairing calcium with D3 covers a common gap in calcium-only formulas, since vitamin D supports how the body absorbs calcium. At 300 softgels, this is sized for long-term daily use rather than a short trial.

Who it's for

Performance notes

Vitamin D3 works alongside calcium by helping the body absorb it more efficiently from the digestive tract, which is why the two are commonly combined instead of sold as calcium alone.
