Thorne Iron Bisglycinate 25mg
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
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

What does the data say about Thorne Iron Bisglycinate 25mg vs Better You Iron Daily ...?
These two iron supplements take completely different approaches to the same problem. Thorne's Iron Bisglycinate delivers 25mg of elemental iron per capsule using Ferrochel® bisglycinate — a chelated form with strong bioavailability evidence and a reputation for being easy on the gut. BetterYou's oral spray bypasses the digestive tract almost entirely, absorbing through the oral mucosa at just 5mg per spray. That's a five-fold difference in dose per serving, which matters considerably if you're trying to correct a genuine deficiency rather than simply maintain levels.
If your GP has flagged low ferritin or you're recovering from iron deficiency anaemia — especially during or after pregnancy — Thorne at £16.99 is the more clinically purposeful option. Multiple users have seen measurable blood test improvements, and the NSF Certified for Sport label adds independent verification of purity. The absence of vitamin C is a minor gap easily fixed by pairing with a glass of orange juice.
BetterYou at £18.98 (pack of three) suits people who've had a rough time with traditional iron tablets — constipation, nausea, the works — or who simply can't swallow capsules. The flavour gets consistent praise, and it's genuinely convenient for travel. Just be aware the pump can become unreliable as bottles empty, and 5mg is a maintenance dose at best.
Thorne Iron Bisglycinate delivers 25 mg of elemental iron in the Ferrochel® chelated bisglycinate form, widely praised in reviews for being exceptionally gentle on the digestive system — no nausea, constipation, or metallic aftertaste that commonly plague ferrous sulfate alternatives.
