L-phenylalanine is essential for the normal functioning of the central nervous system. The body uses phenylalanine to produce epinephrine, dopamine, and norepinephrine. L-phenylalanine helps relieve stress, reduces anxiety and apathy, promotes rapid tissue cell regeneration, helps regulate the metabolic process, improves thyroid function to maintain hormonal balance, and improves skin, nail and hair conditions. L-Phenylalanine is used by professional athletes to give the body the desired shape in a short time. I think this supplement is noteworthy.

Effective as claimed. One must be careful not to exceed the recommended dosage. Works best if not taken every day. Tablets can easily be broken in half.

Phenylalanine is great for mood and muscle pain from fibromyalgia. I bought this because we like Source Naturals, but I realized it was actually the "DL" phenylalanine that I needed. I combine 1500 mgs. DL phenylalanine with 1500 mgs of tryptophan at night and sleep absolutely wonderful. I wake with only minimal pain from fibromyalgia. Really love it for that reason.

I have looked for a good source of L-phenylalynine for years. Health food stores were hit and miss in terms of the products they carried and whether they even had any in stock. And their prices were outrageous. Iherb.com ships almost instantly, their pricing is the best, and everything arrives well packed. Thanks!

At first I have bought it to the dog, but then gave it to the elder woman. She has some thyroid and neuro issues. She evaluated it as good, but of course it did not done any miracle. It would be great it could have less modifications in additional ingredients.
