D‚L-Phenylalanine 500 mg - 100 Vegetarian Capsules from Life Extension® is a supplement that helps in the formation of key hormones in the body required for an energetic life. This vegetarian formula contains phenylalanine‚ an essential amino acid.
Studies suggest that phenylalanine in this formula from Life Extension® normally exists in three forms-D-phenylalanine‚ L-phenylalanine and D‚L-phenylalanine‚ the mixed form. This form acts as a precursor to L-tyrosine in the liver that‚ in turn‚ gives rise to dopamine‚ norepinephrine and ephinephrine known as catecholamines.
Elevated levels of these hormones could promote a positive mood and enhance energy levels. They also play a role in the body’s fight or flight response. Dopamine helps control movement and emotions. Epinephrine is produced in response to stress or excitement. Norepinephrine is a hormone that is the main neurotransmitter of the sympathetic nervous system. It could increase the oxygen supply to the brain and support a healthy mood and feeling of well being.
Many people believe that phenylalanine could support cognitive function and healthy joints. It may also have analgesic properties by blocking the degradation of enkephalins. Switch to D‚L- Phenylalanine 500 mg - 100 Vegetarian Capsules from Life Extension® and enhance your energy levels.
