Very High See all 3 studies |
There does appear to be a fairly effective suppression in appetite noted with 5-HTP supplementation in the higher dosage range, which tends to reduce food intake.

High See all 3 studies |
There may be a role in reducing appetite specifically in persons who self-report inappropriate eating patterns and carbohydrate cravings, with no known effect in persons who do not report such.

- | Low See all 4 studies |
Variable effects on appetite, but it seems the fenugreek fibers (not commonly in supplements) may reduce appetite similar to most dietary fibers while the saponins (commonly supplemented) have no significant effect or a possible increase
