Thorne FX Iron Bisglycinate

Brand: Thorne FX · Form: CAPSULE [E0159]

Our assessment

The evidence shows that iron bisglycinate is generally a well-tolerated form of iron supplementation. For many people, it may cause fewer digestive side effects compared to other iron salts. However, we must be clear: the specific data for Thorne FX Iron Bisglycinate is extremely limited in the provided information. We do not have specific dosage, RDA, or clinical study data for this exact product from the data we are allowed to use.

How it works

Iron is a critical mineral your body needs to produce hemoglobin, the protein in red blood cells that carries oxygen. Iron bisglycinate is a chelated form, where iron is bound to the amino acid glycine. This structure is designed to be gentler on the stomach and may be absorbed more efficiently than other forms like ferrous sulfate [NIH ODS].

Safety profile

Data not available. The provided FDA data does not contain any adverse event reports specifically for Thorne FX Iron Bisglycinate. General iron supplement risks include constipation, nausea, and stomach upset, but specific report counts for this product are not available from the provided data.

Our recommendation

Because the specific data for this product is not available, we cannot make a confident recommendation for Thorne FX Iron Bisglycinate. If you are considering iron supplementation, we strongly advise you to first have your iron levels tested by a healthcare provider. Taking iron when you do not have a deficiency can be harmful. Do not exceed the general Tolerable Upper Intake Level of 45 mg per day unless directed by your doctor [NIH ODS].
