Tyrosine is an amino acid that helps you feel like Superman: It increases energy, elevates mood, boosts focus, drives up muscle strength, enhances sex drive and even aids fat loss. If tyrosine brought you beers, told you that you looked great and paid your bills, you would never need another supplement. But if tyrosine is great, N-acetyl L-tyrosine is even better.
N-acetyl L-tyrosine does all the awesome things that tyrosine does, but it has two further benefits. One, it’s more bioavailable, meaning you can take smaller doses and the body can use more of it. And two, the acetyl part helps tyrosine cross the blood-brain barrier and enter the brain, where it helps produce chemicals like epinephrine, norepinephrine and dopamine, as well as thyroid hormone, which have the one-two punch of boosting energy and bumping fat loss.
You can maximize benefits of the N-acetyl L- tyrosine version with only two doses of 100 to 300 milligrams per day. Take one with breakfast and the other 30 to 60 minutes before you workout.
