Sample excerpts from currently available source material used in this product analysis.
"1 a day helps you work rest and play. Started taking these a while ago, definitely feeling the benefit."

How does Thorne Iron Bisglycinate 25mg score?
Detailed score breakdown and key findings from our analysis of 68 reviews across 3 sources.
Pros
- +Bisglycinate (Ferrochel®) form is highly bioavailable and consistently reported as gentle on the stomach with no constipation or nausea
- +Measurable improvements in ferritin and hemoglobin confirmed by multiple reviewers via blood tests
- +NSF Certified for Sport — independently verified for purity and label accuracy
- +Ultra-clean formula: only pharmaceutical-grade excipients, no magnesium stearate, fully vegan and allergen-free
- +Small capsule size and once-daily dosing make compliance easy
Cons
- -No vitamin C included — absorption is suboptimal without pairing with ascorbic acid (users note this and add their own)
- -25 mg dose may be insufficient for severe iron deficiency recovery; therapeutic correction often requires higher daily intake
- -Premium pricing — noticeably more expensive per serving than ferrous sulfate or gluconate alternatives
- -At least one reviewer with chronic severe malabsorption found no improvement, ultimately requiring IV iron infusion
Best For
Watch Out
- !Always pair with vitamin C (100–200 mg) for maximum absorption — not included in this formula
- !25 mg is a maintenance dose; consult a doctor if ferritin is severely depleted, as higher doses or IV infusion may be needed
- !Note: Trustpilot reviews in this dataset are from a UK beekeeping company also named 'Thornes' — unrelated to the supplement brand
- !Higher cost may not be sustainable for long-term supplementation on a tight budget — comparable chelated iron is available at lower price points
