Overview
•Iron bis-glycinate at 28 mg is well-tolerated with lower GI side effects compared to other iron forms, supported by RCTs showing reduced nausea and constipation.
•Vitamin C at 100 mg enhances iron absorption without exceeding safe upper limits; calcium at 11 mg poses no overdose risk.
•Generally safe for healthy adults, but consult physician if pregnant, lactating, or with conditions like hemochromatosis; not for children under 18 without advice.
•Minimal drug interactions, though may reduce absorption of tetracyclines, quinolones, or thyroid meds if taken simultaneously—space by 2 hours.
•Hypoallergenic and gluten-free formulation reduces sensitivity risks; no major contaminants reported from reputable brand Pure Encapsulations.
•Long-term use safe at this dose for deficiency correction, but monitor ferritin levels to avoid excess iron accumulation.
