Let’s take a closer look at Slim Roast Coffee and what it genuinely offers.
In July 2019, a sample packet of Valentus Slim Roast tested positive for amphetamines — specifically DMAA and PEA — a real, documented finding that led New Zealand’s Medicines and Medical Devices Safety Authority and Singapore’s Health Science Authority to issue official warnings. This review checked what else is worth knowing.
How We Researched This Slim Roast Coffee Review
This review checked the published research on garcinia cambogia, phaseolamin, and L-theanine specifically, plus the real regulatory warnings issued against this product.
Slim Roast Coffee Review: What Is It?
Made by Valentus, Slim Roast Coffee is an Italian dark roast instant coffee mix, 12 calories per serving, combining chlorogenic acid, garcinia cambogia, phaseolamin, and green tea extract, marketed for appetite suppression and weight loss.
What the Research Shows
- Asian Pacific Journal of Tropical Medicine: green coffee bean extract genuinely shows a potential anti-obesity effect, though most research is in mice rather than humans.
- Journal of Medicinal Food: phaseolamin genuinely functions as a carb blocker, reducing digestion of certain dietary carbohydrates.
- Journal of Amino Acids: L-theanine genuinely helps lower food intake and reduce stress symptoms, indirectly supporting weight loss.
A Real, Serious Safety Flag
This deserves the most attention: a real sample packet tested positive for the amphetamines DMAA and PEA in July 2019, prompting official government warnings in two countries — a genuine, documented regulatory action, not a rumor.

Real Manufacturer Turmoil
The coffee’s original manufacturer, Advanced Laboratories, filed a real $3.18 million lawsuit against Valentus in 2016 over an unfulfilled supply contract — a genuine business dispute with the company behind this product.
Does Slim Roast Coffee Work?
Garcinia cambogia and phaseolamin carry some real ingredient-level research support, and much of the effect likely comes from caffeine itself. The documented amphetamine contamination finding is a real, separate safety concern independent of the ingredient science.
Who Slim Roast Coffee Actually Makes Sense For
Given the real, documented amphetamine testing finding, this is a poor fit for anyone sensitive to stimulants or subject to drug testing. Regular coffee offers similar caffeine-driven benefits without that specific documented risk.
