Supply of Ferrous Bisglycinate
- Grades
- Food, supplement and infant-nutrition grades, specified by iron content. The anhydrous chelate carries about 27% iron in theory; commercial grades are commonly specified around 20%, depending on water content and carrier.
- Packaging
- 25 kg fibre drums or cartons with PE liner · Smaller foil packs on request
- Documents
- CoA, SDS and TDS on request; certificate of origin where the destination requires it.
- Delivery
- Worldwide, including the United States, Canada, the United Kingdom, Germany and the rest of the EU, the United Arab Emirates, India, Singapore, Malaysia and Australia. Quoted EXW, FOB, CIF or DAP.
Ferrous bisglycinate is iron bound to the amino acid glycine. It is used to add iron to foods, drinks and infant formula, and in iron supplements. Compared with cheaper iron salts, it changes the colour and taste of food less and is generally easier on the stomach.
Technical details
Ferrous bisglycinate binds a ferrous iron ion between two glycine molecules. It is used where ferrous sulfate, the lowest-cost iron salt, causes problems in the product: in fortified foods the chelated iron reacts less with polyphenols, fats and flavours, so there are fewer grey colours and metallic tastes, and published studies report that its absorption is less held back by the phytate in cereals and legumes. That combination has made it a standard iron source for fortified drinks, dairy and infant nutrition, and for supplements marketed on tolerability. Ehlinar supplies food, supplement and infant-nutrition grades, specified by iron content.
Appearance: Grey-green to brownish powder; slight metallic taste; dispersible to soluble in water.

Frequently asked questions
- Why bisglycinate rather than ferrous sulfate?
- Fewer side effects in the food and, reportedly, in the gut. The chelate reacts less with the rest of the product, so fortified foods keep their colour and flavour, and studies report its absorption is less inhibited by phytate. Ferrous sulfate remains cheaper per milligram of iron.
- What iron content should I specify?
- Most commercial grades are specified around 20% iron. The theoretical figure for the pure anhydrous chelate is about 27%, and the difference is water and carrier. Specify the iron content your label calculation uses and ask for the assay against it.
- Is it permitted in foods?
- Ferrous bisglycinate is on the permitted iron-source lists of many markets, including the EU. Confirm the rules for your product category and destination before you formulate.
- How is it stored?
- Sealed, cool and dry. Ferrous iron slowly oxidises in moist air, so keep containers closed.
