Magnesium taurate, also known as magnesium ditaurate or magnesium taurinate,^[1] is the magnesium salt of taurine, and a mineral supplement.

It contains approximately 8.9% elemental magnesium by mass. Accordingly, 100 mg of magnesium is contained in 1121 mg of magnesium taurate.

Safety

Due to the expected dissociation of magnesium taurate in the body before absorption, safety data on magnesium and taurine can be used to evaluate the safety of magnesium taurate.^[1]

Taurine has an observed safe level of supplemental intake in normal healthy adults at up to 3 g/day.^[2] Using the same level as an approximation for taurate yields a limit of 3.3 g/day for magnesium taurate, or alternatively 300 mg/day for elemental magnesium as taurate.

PMID 18325648. the newer method described as the Observed Safe Level (OSL) or Highest Observed Intake (HOI) was utilized. The OSL risk assessments indicate that based on the available published human clinical trial data, the evidence for the absence of adverse effects is strong for Tau at supplemental intakes up to 3 g/d, Gln at intakes up to 14 g/d and Arg at intakes up to 20 g/d, and these levels are identified as the respective OSLs for normal healthy adults.
