MAS Iron

MAS Iron was developed for a single purpose: to be the most well-absorbed, cutting-edge iron supplement for runners who want to ensure they have the iron they need to perform their best.

So Why Is MAS IRON Better?

MAS Iron combines the most efficiently absorbed form elemental iron with clinically proven ingredients to aid in absorption.

Each ingredient tested alone with iron demonstrated the ability to enhance absorption by 30% to 400%. This is why MAS Iron performs like no other iron product on the market.

4x Better Absorption

The addition of Alpha GPC when taking an iron supplement has been shown to increase absorption up to four times compared with taking iron alone. Alpha GPC has also been shown to increase the absorption of nonheme iron from food sources.

30% Increase in Bioavailability

Clinical research on BioPerine has made it clear that black pepper increases the uptake of iron supplements as much as 30%. Researchers believe this is because BioPerine enhances the bioavailability of iron supplements.

50% Fewer GI Side Effects

Not only is iron bisglycinate better absorbed than all other forms of iron, but research has shown using iron bisglycinate  resulted in 50-percent fewer GI side effects compared to the same dose of iron sulfate.
