The Problem
Meal-replacements that miss the gut.
Most diet shakes are sugar bombs masquerading as health food. They spike blood sugar, leave your gut imbalanced, and fail you within 3 hours. Diet Shake is different.
Skipped meals that crash your blood sugar and metabolism.
Generic shakes packed with sugar and synthetic protein.
No gut support in your shake — just empty calories.
Cravings hit hard a few hours after — back to square one.
The Solution
Meet GutSlim™ Diet Shake.
20g protein, 16 probiotic strains, low-GI carbs, and full vitamin profile — in one delicious shake. Replace a meal cleanly, fuel your gut, lose weight sustainably.
20g clean plant + whey protein per serving.
16-strain probiotic blend for gut and metabolic balance.
Velobiotics™ MEP technology — 1000× more reach your gut alive.
Low GI, low sugar. Doctor-formulated. Lab-tested every batch.
