Description

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.*

FAQs

Frequently asked question

Is Iron Bisglycinate worth buying compared to regular iron supplements?

Iron Bisglycinate is a chelated form of iron, meaning it's bound to amino acids for superior absorption and gentler digestion compared to common forms like ferrous sulfate. Many users experience fewer side effects such as constipation or nausea. If you've struggled tolerating standard iron supplements or need efficient absorption, Iron Bisglycinate is widely considered the premium choice worth the investment.

Who should consider taking Iron Bisglycinate?

Iron Bisglycinate is ideal for women of menstruating age, vegans and vegetarians, frequent blood donors, and anyone diagnosed with or at risk of iron deficiency. According to the CDC, up to 16% of individuals in some populations are iron deficient. If you're experiencing fatigue or low energy, speak with your healthcare provider to determine if an iron supplement is right for you.

How does iron support athletic and sports performance?

Iron is critical for forming healthy red blood cells, which carry oxygen to working muscles. Low iron levels can reduce endurance, increase fatigue, and impair recovery. For athletes — especially those in endurance sports — maintaining optimal iron levels helps support stamina, energy production, and overall performance. Iron Bisglycinate's high bioavailability makes it a smart choice for active individuals.

What is the recommended dosage for Iron Bisglycinate?

Dosage recommendations vary based on age, gender, and individual health needs. Always follow the directions on the product label or consult your healthcare provider for personalized guidance. Avoid exceeding the recommended dose, as excessive iron intake can be harmful. Your doctor can also run a blood test to confirm whether supplementation is necessary and at what level.

Does Iron Bisglycinate cause stomach upset or constipation?

One of the biggest advantages of Iron Bisglycinate over traditional iron forms is its gentle impact on the digestive system. The chelated structure allows for smoother absorption in the gut, significantly reducing common side effects like nausea, cramping, and constipation. Taking it with food can further minimize any mild discomfort, making it a well-tolerated option even for those with sensitive stomachs.
