Ferrous Bisglycinate: The Highly Bioavailable Chelated Iron for Gentle, Effective Anemia Support and Iron Fortification
description1
Product Description
Our Ferrous Bisglycinate is a high-purity, food-grade and pharmaceutical-grade chelated iron produced through controlled synthesis from ferrous iron and glycine, followed by spray drying to yield a fine, free-flowing powder. The product appears as a dark brown or grayish-green crystalline powder with a slight metallic, sweetish taste and excellent water solubility. The chelation is confirmed through analytical characterization, ensuring true chelate formation rather than a simple physical mixture. With an assay of ≥99% and elemental iron content of 19.0–23.8%, it complies with relevant pharmacopeial standards and is manufactured under strict cGMP conditions to ensure consistent particle size distribution and reliable flow characteristics. Its high stability across a broad pH range (remains completely soluble at pH 6, unlike ferrous sulfate which precipitates) allows for flexible incorporation into diverse food and beverage matrices. It is ideal for formulating iron supplements (capsules, tablets, granules, oral liquids), fortified foods and beverages, and clinical nutrition products.

Nutritional Composition
Ferrous Bisglycinate is a high‑quality chelated nutritional iron ingredient. Formed by ferrous ions chelating with glycine, its stable five‑membered‑ring structure delivers superior bioavailability versus common inorganic iron salts. It greatly lowers gastrointestinal irritation risks. With favorable water‑solubility and pH stability, this nutrient is widely used in capsules, tablets and fortified functional foods for effective iron supplementation and prevention of iron‑deficiency anemia. It complies with global food‑grade raw material standards.
Provides Superior Bioavailability with High Absorption Rate
The chelated structure protects the ferrous iron from dietary inhibitors (such as phytates and polyphenols) and allows it to be absorbed intact through the intestinal mucosa via active transport mechanisms. The absorption rate of ferrous bisglycinate is approximately 3–5 times that of ferrous sulfate, with some studies reporting absorption rates up to 95%.
Gentle on the Gastrointestinal Tract with Minimal Side Effects
Unlike conventional iron salts, ferrous bisglycinate does not release free Fe²⁺ ions in the stomach, thereby avoiding the oxidative stress and mucosal irritation responsible for nausea, constipation, and abdominal discomfort. Clinical trials confirm significantly better tolerability compared to ferrous sulfate, with reduced gut inflammation markers.
Effective for Iron Deficiency Anemia Prevention and Treatment
Clinical studies demonstrate that daily supplementation with 30 mg of iron bisglycinate significantly increases serum ferritin levels (from 24.1 to 32.3 ng/mL by day 15) and effectively improves hemoglobin, red blood cell count, and hematocrit in patients with iron deficiency anemia. It is particularly valuable for pregnant women, children, and individuals who cannot tolerate conventional iron supplements.
Improves Cognitive Function and Physical Performance
By correcting iron deficiency, ferrous bisglycinate supports optimal oxygen transport and energy metabolism, which may improve concentration, memory, and cognitive performance. Research also suggests it can help enhance exercise capacity and reduce fatigue in athletes with iron deficiency, even without frank anemia.
01
Dietary Supplements
Formulated into capsules, tablets, granules, and oral liquids for the prevention and treatment of iron deficiency anemia. It is particularly suitable for sensitive populations including pregnant women, children, and the elderly who are prone to gastrointestinal side effects from traditional iron supplements.
01
Functional Foods and Beverages
Used as a nutritional fortifier in dairy products (modified milk powder, fortified milk), beverages (juice, plant protein drinks, solid beverages), baked goods (bread, biscuits, cereal products), meat products, infant formula, soy powder, jelly, and confectionery. Recommended addition levels: 60–200 mg/kg in modified milk powder; 14–26 mg/kg in rice and wheat flour products.
03
Clinical Nutrition and Medical Foods
Applied in enteral nutrition formulas and nutritional support products for patients with iron deficiency anemia, including those undergoing cancer treatment, post-surgical recovery, or with chronic inflammatory conditions.
