Description

Thorne Advanced Iron Complex:  What are the benefits?

Thorne Advanced Iron Complex is a gentle, well-absorbed iron formula designed to raise iron levels without the stomach upset or constipation common to standard iron salts. It features chelated iron bisglycinate for superior tolerability and bioavailability, plus smart cofactors—vitamin C to enhance absorption and methylated B12/folate with supportive minerals (e.g., copper) to promote healthy red-blood-cell formation, hemoglobin production, and oxygen transport. Ideal for athletes, menstruating women, and anyone with increased iron needs, this clean, gluten-/dairy-/soy-free complex supports steady energy, clearer focus, and comfortable daily use. Take with food or as directed, and pair with a quality multivitamin for a complete foundation.

Restore energy and oxygen delivery

Thorne Advanced Iron Complex rebuilds iron stores to support healthy hemoglobin and red-blood-cell production, improving oxygen transport for steadier energy, clearer focus, and better exercise tolerance. Consistent use can reduce symptoms of low iron—fatigue, cold hands/feet, shortness of breath with exertion—so daily life and workouts feel easier.

Gentle, highly absorbable iron

Using well-tolerated iron bisglycinate, this formula minimizes the constipation, nausea, and GI irritation common with standard iron salts, making long-term repletion realistic. The chelated form absorbs efficiently even at modest doses, helping you reach targets without heavy side effects.

Smart cofactors for results

DBuilt-in vitamin C enhances iron uptake, while methylated B12 and folate support red-blood-cell maturation; copper helps balance iron transport and utilization. Together, these cofactors accelerate repletion and help maintain healthy ferritin and hemoglobin—ideal for athletes, menstruating women, and anyone with increased iron needs under a clinician’s guidance.

What are the ingredients?

What it is and why it matters

The main ingredient is iron bisglycinate chelate (often known as ferrous bisglycinate): an iron atom bound to two glycine molecules that stays soluble and resists forming insoluble complexes with common dietary inhibitors like phytates and tannins—features linked to higher bioavailability than standard salts such as ferrous sulfate. In head-to-head nutrition research, bisglycinate has been proposed as a superior alternative precisely because of this absorption advantage. BioMed Central

Absorption and tolerability vs. conventional salts

Conventional iron salts can leave most of the dose unabsorbed in the gut and frequently cause GI upset (nausea, constipation, abdominal pain), whereas clinical literature describes ferrous bisglycinate as efficient at raising iron status with fewer gastrointestinal side effects—a key reason it’s favored for long-term repletion. Recent human data and trials highlight both its effectiveness in improving iron parameters and its improved tolerability profile compared with higher-dose ferrous sulfate regimens. PMC+1

How cofactors help the chelate work even better

Vitamin C is commonly paired with non-heme iron because it chemically reduces and chelates iron, keeping it soluble in the duodenum and thereby enhancing absorption—a mechanism described in classic and contemporary references (even as some modern trials debate the magnitude of clinical impact). This chemistry complements the bisglycinate chelate’s inherent bioavailability, supporting efficient uptake from each dose. PubMed+2OD Service+2
