Studies related to uptake and bioavailability of Ferrochel in amino iron

Clinical study in people with iron deficiency anemia. The study compared the effect of 120 mg iron from ferrous sulphate with 30, 60 or 120 mg iron from bisglycinate. It turned out that even 30 mg iron bisglycinate daily corrected Hb within 4 weeks, while ferritin levels only recovered after 6-8 weeks with 30 mg daily. With a daily dose of 60 mg iron bisglycinate, ferritin levels also recovered within 4 weeks.

30 mg daily was thus a sufficient dose to alleviate iron deficiency anemia, while those taking 60 mg recovered more quickly. This study also showed the gentle effect on the stomach and intestines when taking Ferrochel.

In this randomized double-blind study, 25 mg iron bisglycinate/Ferrochel was compared with 50 mg ferrous sulphate to prevent iron deficiency in pregnant women. It was shown that 25 mg iron bisglycinate was sufficient to prevent iron deficiency during and after pregnancy.

This randomized double-blind clinical trial compared the effect of 30, 60 and 120 mg iron from ferrous glycinate with 120 mg ferrous sulfate in 100 children with known iron deficiency anemia and found that even a daily dose as small as 30 mg iron from ferrous bisglycinate/Ferrochel was sufficient to compete with the effect of 120 mg ferrous sulfate in counteracting anemia within 4 weeks.

In this study, the effect of supplementing with 15 mg iron from ferrous glycinate was compared with 40 mg iron from ferrous sulphate. It was shown that iron bisglycinate/Ferrochel had a significantly better effect on blood parameters during pregnancy than the almost three times higher dose of iron sulphate.

There are many indications that the absorption of iron from Ferrochel is regulated by the body's need for iron, as various studies have shown that the absorption of iron glycine is reduced when hemoglobin increases. This is something that forms the basis for the assessment that the product is safe. In addition, it has been studied in groups such as children and pregnant women without any negative effects.

aminoIron 25 mg is an iron supplement suitable for anyone with iron deficiency. Ferrochel® bisglycinate chelate is well documented in many clinical studies.
