Support for an ingredient is usually built on a specific way of taking it — a powder mixed in water, a capsule swallowed daily, a standardized extract. Change the format and you can change the outcome, sometimes dramatically. A claim that quietly carries the evidence from one delivery route to another is making a bigger leap than it looks.
Creatine is stable as a dry powder. In a moist, slightly acidic gummy it can degrade toward inactive creatinine — the documented cause of widespread failures in published testing.
Where delivery route actually changes things
- Creatine gummies — the format itself is a stability risk, independent of whether the brand is honest. Moisture and acidity break creatine down over shelf life.
- Curcumin — plain turmeric absorbs poorly; the positive trials mostly used piperine or a bioavailability-enhanced form. A plain-curcumin product isn't the studied thing.
- Timing-based marketing — "pre-workout creatine" implies the timing matters, but research attributes the effect to muscle saturation over weeks, not a dose before a workout.
What the check does
LookCloser records how an ingredient was studied — the form, the standardization, the use pattern — and notes when a listing's framing drifts away from it. When the marketing and the mechanism don't line up ("fast-acting" for something that works by saturation; a gummy for something proven as a powder), that's a documented note, not an accusation. The product may still be fine. But the claim is leaning on evidence for a different thing.
Reading this check
- "Taken the way the research studied it" means nothing in the listing contradicts the studied delivery route.
- A mismatch flags a gap between how it's sold and how it was tested — worth a question to the brand, not a verdict.
