2/5 Evidence Score

SlimPro is a fish protein hydrolysate made from the muscle of blue whiting (Micromesistius poutassou) by enzymatic hydrolysis, developed by Compagnie des Pêches Saint-Malo. It supplies small marine peptides that have been studied for their effect on the body's own appetite-regulating gut hormones. In a single controlled trial in slightly overweight adults, taking the hydrolysate alongside a mild reduced-calorie diet raised blood levels of the satiety hormones cholecystokinin (CCK) and GLP-1 and was associated with greater reductions in body weight, fat mass, and body circumferences than placebo over 90 days. No added effect was seen at the higher of the two doses tested. The evidence to date comes from this one manufacturer-affiliated study, so it is best viewed as a supportive part of a reduced-calorie routine rather than a proven stand-alone aid.

Studied Dose Around 1.4 grams per day.
Active Compound A hydrolysate of blue whiting fish protein, providing bioactive peptides that stimulate satiety hormones.

Benefits

Appetite-regulating hormone support

In a controlled trial, the fish protein hydrolysate raised blood levels of the satiety hormones cholecystokinin (CCK) and GLP-1 compared with placebo. These gut hormones signal fullness to the brain, which is how the peptides are thought to support appetite regulation.

Body composition support

Taken alongside a mild reduced-calorie diet, the hydrolysate was associated with greater reductions in body weight, fat mass, and waist, hip, and thigh circumference than placebo over 90 days in slightly overweight adults.

Weight management

By supporting the body's own satiety signals, it is used as one part of a reduced-calorie weight-management routine rather than as a stand-alone solution.

Mechanism of action

1

Gut hormone stimulation

The bioactive peptides trigger enteroendocrine cells to release cholecystokinin (CCK) and GLP-1, hormones that signal fullness to the brain.

2

Reduced hunger signaling

Higher satiety-hormone activity is thought to lower the drive to eat, supporting smaller portions at meals.

Fish protein hydrolysate, body composition, and satiety hormones (RCT)
PubMed

Randomized placebo-controlled study of a blue whiting fish protein hydrolysate at 1.4 and 2.8 grams on body composition and satiety-hormone levels. (Nobile et al. 2016, Food and Nutrition Research)

120 slightly overweight adults (BMI 25 to 30) on a mild reduced-calorie diet.

Over 90 days, both the 1.4 and 2.8 gram doses produced greater reductions in body weight, fat mass, and body circumferences than placebo and raised blood CCK and GLP-1 levels; the two doses did not differ, and placebo also lost some weight from the diet alone.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated.
Mild digestive upset is occasionally reported.
People with fish allergy should avoid it.

Important Drug interactions

Diabetes medication: appetite and glucose effects may interact; monitor.
Take before meals for the intended satiety effect.
Tell your doctor if you manage blood sugar.
