Why most iron supplements fail runners

Iron built for endurance athletes

Runners burn through iron faster than the general population. Sweat, foot-strike hemolysis, and GI stress drain your stores every training cycle. Most supplements weren't designed for that.

Bisglycinate chelate for 2-4x higher absorption than standard iron
No stomach issues. Chelated iron bypasses the GI irritation that makes most iron supplements hard to take
Dosed specifically for endurance athletes, not the general population

Those recipes will help you build a strong iron foundation from food. When training demands outpace what food alone can deliver, MAS Iron fills the gap without the side effects.
