The trunk reaches its floor
Calcium oxide falls as low as ore selection and beneficiation take this oxide before the chemistry itself changes.

MgVanta USP MgO 99 arrives
Manufactured to a USP-aligned specification. The purest point on the ladder.
99.0 % MgO, as ignited

Purity earns the label
The densest common magnesium salt. Light or heavy density, specified at quote, because your press expects one of them.
60.30 % elemental Mg

Stage 04
One thing purity cannot fix
Two lots can both read 99% and still behave differently in a press. That is why we specify reactivity, not only assay.

Note
Manufactured to a USP-aligned specification for magnesium oxide. Conformance testing against the monograph is available on request. The certificate of analysis states exactly which tests have been performed on your lot. Specify light or heavy grade at the time of quote: the two are not interchangeable in a tablet press, and the certificate states the bulk density. Antacid drug use and dietary supplement use sit under different US frameworks, and the requirements follow your finished product.
