Does This Sound Familiar?

You wake up tired and push through the day on willpower alone. You've cut carbs, skipped meals, hit the gym — and the number on the scale barely moves.

The afternoon slump hits, the cravings show up right on schedule, and you're back where you started. Frustrated. Discouraged.

It's not a discipline problem. A sluggish metabolism can work against you no matter how hard you try — and that's exactly what Slim Coffee Booster was built to support.

Built From Seven Targeted Ingredients

Each sachet combines natural extracts chosen for how they support metabolism, fullness, and steady blood sugar.

Wellaray Slim Coffee Booster box and sachet
01

Green Coffee Bean Extract

Rich in chlorogenic acid, a compound long associated with supporting metabolism and moderating carbohydrate absorption.

02

Green Tea Extract

Traditionally used to support a more active metabolism, alongside general heart and cardiovascular wellness.

03

L-Carnitine

An amino acid involved in shuttling fatty acids into cells, where they're converted into usable energy.

04

Mulberry Leaf Extract

May help slow sugar absorption after meals, supporting steadier blood sugar and fewer cravings.

05

Resistant Dextrin

A soluble fiber that supports a feeling of fullness and feeds beneficial gut bacteria.

06

Psyllium Husk

Expands with water to support fullness, while also supporting healthy digestion.

07

White Kidney Bean Extract

May help moderate how carbohydrates are broken down and absorbed during digestion.

Dr. Jan Vogler, M.D.

"Most weight-management struggles come down to two things — a slow metabolism and unstable blood sugar. Slim Coffee Booster's formula was built to address both in a single daily sachet, and it's one of the more thoughtfully put-together natural formulas I've reviewed."
