Mcgrocer Review 2026: Misleading Claims
HypeCheck's analysis of Mcgrocer rates it 7/10 on the hype scale with a verdict of Misleading. Holland & Barrett's Raspberry Ketone Complex is a multi-ingredient weight management supplement whose headline ingredient — raspberry ketones — has no meaningful human clinical evidence for fat...
Hype Score
0 = legit, 10 = all hype
"It's a multi-ingredient weight loss capsule built around raspberry ketones — a trendy-sounding compound with zero human evidence for fat burning — padded out with Garcinia Cambogia, green tea extract, caffeine, and vitamins."
Bottom line: This is an overhyped weight loss supplement built around an ingredient (raspberry ketones) that simply doesn't work in humans, combined with a potentially risky one (Garcinia Cambogia), sold without transparent dosing information.
Consumer advice
Skip this product. If you want the only genuinely evidence-backed ingredients in this formula (caffeine and green tea extract), a cup of coffee or a standalone green tea extract supplement will give you a known dose at a fraction of the price. Do not use this product if you have any liver concerns — Garcinia Cambogia has a documented hepatotoxicity risk. There is no credible human evidence that raspberry ketones, the product's namesake ingredient, do anything for weight loss at supplement doses.
