This form is picked for digestive tolerability and is produced to meet high purity standards to support sensitive people seeking reliable magnesium intake.

What Does Magnesium (Buffered Oxide Form) Do?

Magnesium is involved in over 300 enzymatic reactions and helps normal muscle function, nerve function, and bone health. NHS guidance highlights its role in these processes, with EFSA recognising magnesium as part of regular bodily function and maintenance.

In addition to helping neuromuscular and bowel function, this buffered form is noted for improved tolerability in sensitive individuals, contributing to ongoing daily physiological balance.
