Iron bisglycinate FAQs
What is Iron Bisglycinate?
Iron Bisglycinate is one of the most effective and gentle forms of iron for maintaining healthy blood and energy levels. It’s a chelated form of iron, bound to the amino acid glycine, which enhances absorption and helps reduce common side effects like nausea or constipation that are often linked to other iron forms such as ferrous sulfate.
Is Iron Bisglycinate better than Ferrous Sulfate?
Yes, studies show that Iron Bisglycinate provides superior absorption and is gentler on the stomach than ferrous sulfate. While ferrous sulfate is effective, it can commonly cause digestive discomfort and constipation, making bisglycinate the preferred option for long-term use.
How much Iron Bisglycinate should I take for anaemia?
For those with iron deficiency anaemia, a typical dosage ranges from 25mg to 50mg elemental iron daily, depending on individual needs. Always consult a healthcare professional before supplementing, as requirements vary by age, gender, and medical condition.
How long does Iron Bisglycinate take to work?
Many people notice improvements in energy and wellbeing within 2–4 weeks, though it can take up to 3 months to restore healthy iron stores. It’s important to continue supplementation as directed and recheck iron levels through blood tests.
Can I take Iron Bisglycinate with other supplements?
Yes, but it’s best taken away from calcium, zinc, or caffeine, which can interfere with absorption. Vitamin C (ascorbic acid) enhances iron uptake, so pairing it with a vitamin C supplement or citrus juice is beneficial.
How much iron do I need daily?
According to the NHS, adults typically need:
- Men (19+): 8.7mg per day
- Women (19–50): 14.8mg per day
- Postmenopausal women: 8.7mg per day
Iron needs may increase during pregnancy or if you follow a plant-based diet.
