L-Tyrosine is an amino acid that is used to produce noradrenaline and dopamine. It is one of the 22 amino acids used by cells to synthesize proteins. It is considered a nonessential amino acid, as the body can produce L-Tyrosine from dietary L-Phenylalanine by way of the phenylalanine hydroxylase enzyme. The body then can convert L-Tyrosine into L-DOPA, using the tyrosine hydroxylase enzyme. This is considered a rate-limiting step, as the body can up/downregulate the enzymes to control how much of a specific amino acid is created. Supplementing L-Tyrosine bypasses one of the body's rate-limiting enzymes, and results in larger increases in dopamine production at a faster rate.
Product includes one 125g or 500g jar of L-Tyrosine Powder.

This is the only only L-Tyrosine I've ever purchased from any supplier, so I can't really add any comparison to thos review. With that said, my 1st batch of L-Tyrosine purchased right here from Nootropics Depot was and is some fantastic stuff. It has definitely increased my motivation levels long term and even if I skip a day or two without using it my motivation is still pretty much above baseline, which leads me to the following. I have been below baseline for some years. Although I had some motivation to get things done, I wouldn't always do them or would only do a few and go lay down or do some other minuscule task that wasn't even on my list to get sh*t done (GSD). I have been using it for about 3-weeks now at different quantities and in different solutions. Ive used it in small quantities, about 200mg capsulated and as high as 3.2g in my coffee. It has no taste at all that I can notice and only took away the sweetness to my coffee requiring me to add additional sweatner. The motivation was a sneaky onset that lasted for hours but was very obvious. After taking that 3.2g I fixed my door, bolted my shelf to the wall, cleaned my desk,went shopping, cleaned my bathroom, read a bunch of Nootropic articles, bought a power supply form a guy on offer up and fixed my computer. I have been meaning to do all these for months. I guess my motivating dopamine levels were extremely low. Now I just need to know why. Some good stuff and Im glad I bought it, oh and did I say, 125g which is 125,000mg cost less then $9.00 crazy. Happy with the product and I'm happy with the cost. The shipping was expensive and Im not sure why but what ever. Donte Beachem on 12th Apr 2017
