5-HTP The amino acid 5-HTP is found in foods like milk, meat, potatoes, pumpkin, and various greens, and it is converted into serotonin in the brain, which is one of the principal neurotransmitters involved in feelings of happiness. Research shows that when taken with food, 5-HTP increases feelings of fullness and thus helps you control your food intake.91 Furthermore, studies have demonstrated that 5-HTP’s satiety mechanism can reduce cravings for carbohydrates in particular.92
