Iron Bisglycinate NSF

Iron Bisglycinate Details

Iron is essential to the formation and function of healthy red blood cells.‡ An adequate amount of dietary iron is required for blood cells to efficiently transport oxygen throughout the body. According to the U.S. Centers for Disease Control (CDC), up to 16 percent of individuals in some populations is deficient in iron. 

Individuals who can be prone to iron deficiency include:

• Women of menstruating age
• Individuals who follow a vegan or vegetarian diet
• Frequent blood donors
• Individuals who have undergone gastric bypass surgery
• Individuals who eat a very high fiber diet, which can inhibit iron absorption
• Individuals recovering from blood loss, such as injury or surgery
• Performance athletes who have any of the above additional risk factors

Signs of iron deficiency:

• Fatigue or weakness
• Shortness of breath
• Pale skin
• Cold hands and feet
• Feeling lightheaded or dizzy
• Changes in menstrual cycles
• Decreased athletic performance

 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 more than 200 substances banned by many major athletic organizations.

What is iron bisglycinate used for?

Iron bisglycinate helps support healthy red blood cell production and oxygen transport, especially in individuals with low iron levels. Thorne’s formula uses a gentle, chelated form of iron that’s well absorbed and easier on the stomach. It is ideal for those with fatigue, low energy, or iron deficiency.

Is iron bisglycinate easy on the stomach?

Yes. Unlike standard forms like ferrous sulfate, iron bisglycinate is less likely to cause nausea, constipation, or stomach upset. It’s bound to the amino acid glycine, which improves absorption and makes it a better option for those who struggle with traditional iron supplements.

Who should take iron bisglycinate supplements?

This form of iron is ideal for women of menstruating age, vegans, vegetarians, athletes, and anyone recovering from blood loss or surgery. It’s also helpful for people with poor iron absorption due to high-fiber diets or gastrointestinal surgery. Thorne’s NSF Certified formula is trusted by professionals and safe for daily use.
