Advanced Iron Complex
# Why We Chose This Iron is fundamental to oxygen delivery—the circulatory backbone that powers every workout, every hike, every active day you want to feel strong through. Thorne's Advanced Iron Complex addresses a gap many active people don't realize they have, especially those following plant-based diets or managing demanding training schedules that can deplete iron stores.
Thorne Advanced Iron Complex is designed for individuals who need reliable iron support without the gastrointestinal discomfort associated with conventional iron supplements. Formulated to support healthy red blood cell formation and efficient oxygen transport, it is a considered choice for those with elevated iron needs.
Iron is essential to the formation and function of healthy red blood cells.* An adequate amount of iron in the diet 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 certain populations are deficient in iron.
Individuals who are prone to be iron or B vitamin deficient include:
- Individuals looking for nutritional support for anemia
- Women of menstruating age
- Individuals who follow a vegan or vegetarian diet
- Older individuals and others who tend to have less stomach acid
- Individuals who have undergone gastric bypass surgery
- Those who have intestinal conditions that affect nutrient absorption
- Individuals with an autoimmune disorder
Signs of an 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 Ferrasorb contains iron reacted with glycine to enhance its absorption in the gastrointestinal tract, thus helping to decrease the typical side effects of iron supplementation.*
Why vitamin cofactors? Iron is not the only nutrient essential for healthy red blood cells. Having a deficiency in the B vitamins can also lead to adverse issues with red blood cell formation.*
Signs of B vitamin deficiency:
- Fatigue or muscle weakness
- Decreased mood quality
- Sores in the mouth or on the tongue
- Problems with memory or cognition
- Feeling of being on “pins and needles”
Ferrasorb combines the active forms of vitamin B6 (pyridoxal 5'-phosphate), vitamin B12 (methylcobalamin), and folate (L-5-methyltetrahydrofolate), along with vitamin C, with a well-absorbed form of iron – offering comprehensive nutritional support for anemia.*
Features of Thorne’s Ferrasorb:
- Iron provided in chelated form for optimal absorption*
- Reduced GI side effects, such as nausea and constipation*
- Provides 36 mg of elemental iron per capsule as Ferrochel® chelate
- Active forms of vitamins B12, B6, and folate, with vitamin C for an enhanced approach to red blood cell health*
Suggested Use:
Take 1 capsule one to three times daily or as recommended by your health-care practitioner.

INTERACTIONS
5-methyltetrahydrofolate (5-MTHF) supplementation is not recommended concurrent with methotrexate cancer therapy, as it can interfere with methotrexate's anti-neoplastic activity; however, this folate source has not been shown to interfere with the anti-inflammatory activity of methotrexate. An individual taking methotrexate for psoriasis or rheumatoid arthritis can safely take a supplement containing folate.
ADDITIONAL WARNINGS
Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under six. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.
