✛ Why it's used

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 an athlete needs to know that his or her 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, including stimulants, narcotics, steroids, diuretics, beta-2 agonists, and masking agents.

Suggested use

Take 1 capsule daily or as recommended by your health professional.

⚠ Key cautions

Cautions: iron should not be supplemented without a clinical indication (confirmed deficiency) in men and postmenopausal women, given the risk of iron overload; chelated bisglycinate form causes less GI upset (nausea, constipation) than ferrous sulfate but GI effects can still occur. Accidental overdose is a leading cause of fatal poisoning in young children — store securely. Prescription interactions: no known adverse drug interactions at publication date, but iron reduces absorption of levothyroxine, tetracycline/fluoroquinolone antibiotics, and levodopa — separate dosing by several hours. Priority: Moderate — effective and well-tolerated for confirmed deficiency, but inappropriate for empiric/unscreened use in men or postmenopausal women given iron-overload risk.
