A combination of 3 label ingredients.
magnesium oxide: Supports normal muscle function; small studies found oxide less well absorbed than citrate, with possible laxative effects.
Supports the maintenance of normal bones and teeth, muscle function and nerve signaling.
Titanium DioxideColorant
Banned in the EU (2022) over concerns that its ultra-fine particles may damage DNA in gut cells. Still allowed in the US. Used only for white coloring — provides no health benefit.

Croscarmellose SodiumDisintegrant
Cross-linked cellulose derivative used as a superdisintegrant
HypromelloseCapsule
