There are some case studies regarding the benefits of L-Phenylalanine USP. A study conducted by the Department of Gastroenterology at St. Bartholomew’s Hospital in London found that administering L-phenylalanine to 10 participants before meals reduced food intake and increased levels of cholecystokinin (CCK), a hormone that stimulates digestion and helps keep appetite under control. Another study found that D-phenylalanine was effective in reducing chronic pain.
The recommended dosage of L-Phenylalanine USP varies depending on the individual’s specific condition. As medicine, L-phenylalanine has most often been used by adults in doses of 250 mg or 100 mg/kg by mouth daily for up to 3 months. However, individual needs vary, so it is best to speak with a healthcare provider to find out what form and dose might be best for a specific condition.
There are potential side effects of L-Phenylalanine USP. When taken by mouth, L-phenylalanine is possibly safe when used as medicine short-term.
