Thorne Advanced Iron Complex

Product overview

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 Advanced Iron Complex 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”

Advanced Iron Complex 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 iron-deficiency anemia.*
