▸ Editor's verdict SKIP-FOR-NOW MEDIUM
"L-phenylalanine is upstream of L-tyrosine in the catecholamine pathway, but L-tyrosine is the rate-limited step and is consistently better-studied for acute cognitive/stress applications. Supplementing phenylalanine to boost catecholamines is a strictly inferior choice vs. tyrosine. The DL-form (DLPA) has weak/anecdotal evidence for chronic pain and depression via enkephalinase inhibition. For an athlete with adequate dietary protein (which provides ~2-4g phenylalanine/day), supplemental phenylalanine doesn't fix any actual problem. Skip unless there's a specific opioid-mediated pain use case being explored."
