How It Works

Iron is difficult for the body to absorb, and supplementing with conventional forms of iron, including ferrous sulfate, can cause gastrointestinal side effects – such as nausea, vomiting, constipation, diarrhea, and dark-colored stools. Thorne's Iron Bisglycinate contains iron reacted with glycine to optimize its absorption in the gastrointestinal tract, thus minimizing the typical side effects of iron supplementation.*

Features of Thorne’s Iron Bisglycinate:

Iron provided in a chelated form for optimal absorption
Reduced GI side effects, such as nausea and constipation*
Provides 25 mg of elemental iron per serving as Ferrochel® chelate
NSF Certified for Sport®

Because athletes need to know their supplements are trustworthy and compliant, every batch of an NSF Certified for Sport® product is tested for compliance with label claims and to ensure the absence of nearly 300 substances banned by many major athletic organizations.
