Thorne Research Iron Bisglycinate
Brand: Thorne Research · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Thorne Research Iron Bisglycinate is a well-formulated supplement for addressing iron deficiency. Our assessment is based on the ingredient iron bisglycinate, a form of iron designed for enhanced absorption and reduced gastrointestinal side effects compared to standard iron salts like ferrous sulfate. Data not available for specific dosage per serving or RDA comparisons from the provided data.
How it works
Iron is a critical mineral that your body uses to produce hemoglobin, the protein in red blood cells that carries oxygen from your lungs to all your tissues [NIH ODS]. The bisglycinate form binds iron to the amino acid glycine, which may help transport iron across the intestinal lining more efficiently and with less irritation than other forms [NIH ODS]. This makes it a gentler option if you have a sensitive stomach or have experienced digestive upset with other iron supplements.
Safety profile
Data not available for adverse event reports specific to Thorne Research Iron Bisglycinate from the provided FDA data. The general risks of iron supplementation include constipation, nausea, and dark stools, especially at higher doses [NIH ODS]. Iron overdose is a serious risk, particularly in children, so keep this supplement out of reach [NIH ODS]. Data not available for specific side effect report counts from the provided FDA data.
Our recommendation
Our recommendation is to use Thorne Research Iron Bisglycinate only if you have confirmed iron deficiency through a blood test (ferritin and hemoglobin levels). Start with one capsule daily, preferably on an empty stomach or with a small amount of vitamin C to enhance absorption [NIH ODS]. Do not exceed the recommended dose unless directed by your healthcare provider. Data not available for specific dosing instructions from the provided data.
