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 Active Iron for Women ...?
Both products tackle iron deficiency but take meaningfully different approaches. Thorne Iron Bisglycinate uses the Ferrochel® chelated form, which is clinically recognised for superior absorption and consistently gentle on the gut — reviewers confirm this via blood tests showing real ferritin improvements. Active Iron uses a whey protein matrix to slow iron release in the stomach, also reducing side effects, but pairs it with a B-complex targeting energy and hormonal balance. At 25mg elemental iron, Thorne's dose is fixed and transparent; Active Iron doesn't list its elemental iron dose clearly, which makes direct comparison tricky.
If you're dealing with confirmed iron deficiency anaemia or have had terrible experiences with ferrous sulphate causing constipation, Thorne at £16.99 is the more clinically credible option — especially with its NSF sport certification confirming label accuracy. For women who want iron plus B-vitamins in one capsule and prefer something that can be taken on an empty stomach, Active Iron at £19.95 scores higher on effectiveness (90 vs 84) and value (80 vs 68).
One practical point: Thorne contains no vitamin C, so you'll need to pair it with ascorbic acid yourself for optimal absorption. Active Iron contains milk protein, ruling it out for vegans or those with dairy sensitivities — and it carries no third-party testing certification, which matters if purity is a priority for you.
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.
