Thorne Iron Bisglycinate: Optimal Absorption for Vitality and Performance*

Iron is an essential mineral vital for the formation and proper function of healthy red blood cells. An adequate amount of dietary iron is crucial for blood cells to efficiently transport oxygen throughout the body. According to the U.S. Centers for Disease Control (CDC), iron deficiency affects a significant portion of individuals in some populations, with up to 16 percent being deficient.

Thorne’s Iron Bisglycinate offers a well-absorbed form of iron specifically designed to minimize common gastrointestinal side effects often associated with conventional iron supplements. It helps resist fatigue and other effects of iron deficiency, making it ideal for women, athletes, and others at risk.*

Individuals Prone to Iron Deficiency:

  • 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

Common 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

While iron is known to be difficult for the body to absorb, and conventional forms like ferrous sulfate can cause side effects such as nausea, vomiting, constipation, diarrhea, and dark-colored stools, Thorne’s Iron Bisglycinate addresses this. It contains iron reacted with glycine (a chelated form) to optimize its absorption in the gastrointestinal tract, thereby minimizing these 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 and health-conscious individuals need trustworthy and compliant supplements, every batch of an NSF Certified for Sport® product undergoes rigorous testing to ensure compliance with label claims and the absence of nearly 300 substances banned by many major athletic organizations.
