Our Verdict: Thorne Iron Bisglycinate or BetterYou Iron Daily Oral Spray?
Thorne Iron Bisglycinate wins clearly, scoring 84 vs 71 and delivering a clinically validated 25mg dose in NSF-certified Ferrochel® form with documented ferritin improvements. BetterYou's spray suits those who cannot swallow capsules and need only a gentle 5mg maintenance dose, though its unreliable pump mechanism is a recurring frustration.

Thorne Iron Bisglycinate scores 84.0/100 vs BetterYou Iron Daily Oral Spray at 71.0/100. Thorne Iron Bisglycinate wins on effectiveness, ingredient quality, value for money.
Thorne Iron Bisglycinate vs BetterYou Iron Daily Oral Spray: What Does the Data Say?
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.
