Source Naturals L-Tyrosine -Free Form Amino Acid Supplement - 100 Tablets

This is my favorite amino! I'm not able to take B vitamins or coffee for energy because it has the opposite effect on me so this is one of the only things that helps me with energy levels!

High qualify supplement. After taking this for a week, I can say that I feel more alert and mentally focused.

I really appreciated the extra energy and focus from this supplement. I did not take it every day, only when I woke up tired or knew I had a demanding day before me. The size of the tablet is not an issue for me as I just chew it into chunks that are easily swallowed with a glass of water. The taste is very bland with a ever so slight sweetness.However, I quit taking it altogether when I realized it was causing me to have uncomfortable urinary urgency. I stopped and started many times and always experienced the urinary urgency on the days I took the tyrosine. I have no idea what about it is causing the irritation, but I reluctantly had to say, "No more!"

This is the only brand of L-Tyrosine I have yet to try but it definitely makes a difference and based on other reviews I'm going to stick with this company. Make sure if you're one of those severe migraine sufferers, read up before you take all l-tyrosine because it could make your condition worse unfortunately. For everyone else, this is a pretty good supplement.

I recently got a new job that is extremely demanding and I also moved and the stress of the situation was hard to manage but after taking the supplement for a week I noticed a impressive boost in my cognitive ability and capacity to manage stressful situations effectively. Really helpful. Read the Wikipedia about l tyrosine for more details.

I was buying Solaray L-Tyrosine capsules and decided to try and save a bit and switch to Source Naturals. I take Source Naturals magnesium so I figured this capsule would be similar in size, its huge.

It was suggested by my physician to supplement with L-tyrosine to boost my thyroid function (i was low normal). What an improvement in energy and mood. Although these are 500 mg tablets, i cut them in half, and that seems better suited for my needs.

Excelente producto, muy buena calidad
