L - Phenylalanine

L-Phenylalanine (PA) is an essential amino acid discussed in Dr. Slagle's book The Way UP From Down. Used to help low mood, low energy, low drive & motivation, maintaining healthy weight*.

Fifty to seventy-five percent of L-Phenylalanine is converted to L-Tyrosine in your liver so all that applies to tyrosine applies to L-Phenylalanine.*

The rest of L-Phenylalanine is converted to other products which account for it having some additional effects beyond those of tyrosine. One other product is the neurotransmitter phenylethylamine (PEA) which has amphetamine-like effects, meaning it is mentally & physically stimulating. Studies have shown some depressed people have lower levels of PEA. These people may find phenylalanine helpful with their low moods.*

Besides producing norepinephrine, dopamine, epinephrine, adrenaline & thyroid, phenylalanine is also a constituent of important brain neuropeptides, somatostatin, vasopressin, melanotropin, ACTH, substance P, encephalin, vasoactive intestinal peptide, angiotensin II, & cholecystokinins.*

Because of its cholecystokinin effect, PA can help maintain a appetite.*

After numerous years of prescribing amino acids, Dr. Slagle has come to first prefer the use of tyrosine over PA for treating dmental health, healthy thyroid & stress relief. She has found tyrosine to virtually be without side effects, while PA can produce some side effects.*

It is also possible some people don't adequately convert PA to tyrosine because she has found more low moods in those with a high PA to tyrosine ratio & less low moods in those with a 2:1 tyrosine to PA ratio. Tyrosine is one step closer to most desired end products.*

Avoid if you have hyperthyroidism, hypertension, or a history of melanoma.

Avoid with schizophrenia.
