THORNE Advanced Iron Complex Chelated Iron Supplement, 60 Capsules — 36 mg, Gentle Absorption

THORNE Advanced Iron Complex is a chelated iron supplement delivering 36 mg of well‑absorbed iron bisglycinate per capsule, paired with B vitamins and vitamin C to support iron uptake and nutrient balance.

This formula combines a non‑constipating form of iron with bioactive B vitamins and vitamin C to help maintain normal iron levels as part of a balanced diet. Each capsule supplies iron bisglycinate, methylcobalamin (B12), pyridoxal‑5'‑phosphate (B6), and L‑5‑MTHF (folate), while manufacturing undergoes multiple testing rounds to verify purity and potency.

How is this iron different from ordinary iron tablets?

THORNE uses iron bisglycinate, a chelated form that is gentler on the digestive tract than many ionic iron salts. The chelation helps reduce common gastrointestinal side effects while allowing iron to be delivered in a form that many people tolerate better.

• 36 mg elemental iron per capsule as iron bisglycinate
• Formulated to be less likely to cause constipation or stomach upset
• Paired with vitamin C and B vitamins to support absorption and utilization
• Manufactured with multiple quality control tests for consistency

What do the added B vitamins and vitamin C do in this formula?

The included B vitamins are supplied in active forms: methylcobalamin (B12), pyridoxal‑5'‑phosphate (B6), and L‑5‑MTHF (folate). These co‑nutrients play supporting roles in energy metabolism and cellular processes that work alongside iron, while vitamin C helps promote iron uptake when consumed as directed.

• B12 as methylcobalamin for bioactive support
• B6 as pyridoxal‑5'‑phosphate for metabolic synergy
• Folate as L‑5‑MTHF for a readily usable form of folate
• Vitamin C included to help with iron absorption from the gut

How should I take THORNE Advanced Iron Complex safely?

Follow the label directions or your health practitioner's advice. Iron supplements are best taken with food if they cause stomach upset; spacing them from calcium‑rich foods or supplements can help optimize absorption.

• Take as directed on the product label or by a practitioner
• Avoid taking at the same time as high‑calcium meals or supplements
• Consult a healthcare provider before starting, especially if pregnant or nursing
• Keep out of reach of children—iron can be harmful in accidental overdose

What quality controls back this supplement?

THORNE performs multiple quality checks across the production cycle to ensure raw material purity and finished‑product stability. The brand is also widely used by professional sports teams and recommended by practitioners, reflecting a focus on testing and traceability.

• Four rounds of laboratory testing from raw materials to finished formula

Who is this for: THORNE Advanced Iron Complex is intended for adults seeking a high‑potency, well‑tolerated iron supplement available with co‑nutrients that support iron utilization. It’s a practical choice for people advised by healthcare professionals to address low iron or who prefer a chelated iron form with active B vitamins and vitamin C; it is not a substitute for professional medical advice or diagnosis.
