FAQs
Frequently asked
Why is iron bisglycinate better tolerated than ferrous sulfate?
The bisglycinate chelate shields iron from interacting with intestinal receptors that trigger nausea and constipation, common side effects of ferrous sulfate.
Can I take iron bisglycinate with food?
Yes, iron bisglycinate is generally well-tolerated with food, which can further minimize potential stomach upset. However, avoid taking it with calcium or tannin-rich drinks.
How long does it take to see results from iron bisglycinate?
Improvements in fatigue and pallor can begin within 2-4 weeks, with significant normalization of ferritin and hemoglobin levels typically observed after 3-6 months of consistent daily dosing.
Research summary
