Polysaccharide Iron Complex vs Ferrous Bisglycinate: Which Iron Supplement Is Better?

Iron deficiency is a common health concern, and choosing the right supplement is crucial. Two popular options are polysaccharide iron complex and ferrous bisglycinate. This article compares their benefits, absorption rates, and side effects to help you decide which is best for your needs.

1. Absorption and Bioavailability
– Polysaccharide Iron Complex: This non-ionic iron supplement is gentle on the stomach and has moderate absorption. It releases iron slowly, reducing gastrointestinal irritation.
– Ferrous Bisglycinate: A chelated form of iron bound to glycine, it has superior bioavailability and is absorbed more efficiently, even in the presence of dietary inhibitors like phytates.

2. Side Effects and Tolerance
– Polysaccharide Iron Complex: Causes fewer digestive issues (e.g., constipation, nausea) compared to traditional iron salts, making it suitable for sensitive individuals.
– Ferrous Bisglycinate: Highly tolerated with minimal side effects, as the chelation process prevents free iron from irritating the gut.

3. Dosage and Effectiveness
– Polysaccharide Iron Complex: Requires higher doses due to lower elemental iron content but is effective for mild deficiencies.
– Ferrous Bisglycinate: More potent per milligram, making it ideal for severe deficiencies or those with absorption issues.

4. Cost and Availability
– Polysaccharide Iron Complex: Generally more affordable and widely available.
– Ferrous Bisglycinate: Slightly more expensive but offers better absorption, potentially reducing long-term costs.

Conclusion
If you need a gentle, budget-friendly option, polysaccharide iron complex is a good choice. For better absorption and minimal side effects, ferrous bisglycinate is superior. Always consult a healthcare provider before starting any supplement.

By understanding these differences, you can select the best iron supplement for optimal health.
