Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®)

Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®) is a Mineral supplement available in 1 form.

Not all forms of Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®) are equal. The form you choose determines how much Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®) actually reaches your tissues, and the difference between the best and worst forms can be substantial. Ferrochel (ferrous bisglycinate chelate) delivers 2-4x greater iron absorption than ferrous sulfate with dramatically less GI side effects (nausea, constipation, dark stools). The chelated form is not affected by dietary inhibitors like phytates, tannins, and calcium — allowing it to be taken with meals or other supplements without absorption interference.

Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®) Preferred (Preferred Form) has a bioavailability rating of good (S2). Typical dose range: not yet documented in our database.

Ferrous bisglycinate chelate (Ferrochel) is the most bioavailable and best-tolerated oral iron form. Multiple clinical trials demonstrate 2-4x greater absorption compared to ferrous sulfate, with significantly less GI distress (nausea, constipation). The chelated form does not interact with dietary inhibitors like phytates and tannins, and can be taken with or without food.

Iron bisglycinate chelate demonstrated 2-4x greater bioavailability than ferrous sulfate in iron-deficient women, measured by serum ferritin response. PMID: 10837299

2023 meta-analysis of 18 RCTs confirmed bisglycinate chelate achieves equivalent iron repletion at lower doses with 64% fewer GI adverse events vs sulfate. PMID: 36728680

Chelated iron transport via dipeptide pathway resists inhibition by phytate, polyphenols, and calcium that reduce non-heme iron absorption by 50-90%. PMID: 35358119

Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®) is classified as Preferred Form by FormulaForge — our top recommendation for Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®). It carries a bioavailability rating of good (S2), meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.

When choosing a Iron (as Ferrous Bisglycinate Chelate) (Ferrochel®) supplement, look for the S1 (best absorption) bioavailability tier on the label. Preferred Forms have the strongest research-backed evidence for efficient absorption.
