Phenylalanine can help with weight control because it participates in processes that regulate food intake and give the body a feeling of satiety. Phenylalanine is an amino acid that can be found naturally in foods rich in protein, such as meat, fish and milk and dairy products, and in the form of supplements sold in pharmacies and health food stores.
The use of phenylalanine supplements must be prescribed by the doctor or nutritionist and is contraindicated for people with problems such as hypertension, heart disease and pregnant women.
Action of phenylalanine on hunger control
Phenylalanine acts in the control of hunger because it participates in the formation of dopamine and norepinephrine, substances that are important for the regulation of food intake and that are also involved in the control of learning, mood and memory. In addition, phenylalanine stimulates the production of the cholecystokinin hormone, which acts in the intestine and gives the body a feeling of satiety.
Usually the recommended dose of phenylalanine is 1000 to 2000 mg per day, but it varies according to the person's characteristics, such as age, physical activity and the presence of problems such as stress and anxiety. However, phenylalanine supplementation alone is not enough to lose weight, since weight loss only happens when there is also a healthy diet.
