I've been taking L-Tyrosine for about 6 months for low thyroid function and notice a HUGE difference in my symptoms. Hair loss has diminished, depression is under control, skin dryness has improved...and I take no other medication for any of these things! I would highly recommend this product for anyone who suspects low thyroid function to be an issue.

My doctor prescribed me l-phenylanine to help me deal with moodswings after hard workout/tournaments. Since its cheaper for me to order it from iherb, than buy with prescription at pharmacy here, i bought both l-phenylanine and "just for fun" l-tyrosine. The l-phenylanine gave me a bad headache, while l-tyrosine somehow (and very unexpected) brought relive to the mood swings (and yes, i know it shouldnt -but it does) ..so, thumbs up L-Tyrosine.
the FOG is lifting...

I'm taking this within the following combination:Doctor's Best Best L-Tryptophan-500 mg, Now Foods-L-Tyrosine-500 mg. and Now Foods 5-HTP-100 mg. I found that I MUST take them before bed, but I do seem to sleep very well with them. What I noticed in the last couple weeks is that I am more perceptive, alert and decisive than usual. I feel like I'm coming out of the "FOG" so-to-say.

Tyrosine is great for stress. An herbalist recommended it for calming nerves. It is also great for the thyroid, depending on the issue. I feel very calm in spite of stressful situations when I use tyrosine. I-Herb always delivers fast so no complaints!

Not too sure how it would work by itself as Im taking DMAE, Tyrosine, Phenylalanine and Theanine in the morning for mild depression and lack of concentration. The cocktail definitely improved my mood, energy and confidence at work. Laughters pop up naturally and easier now... I'm happy with the results, no need to take other doses during the day and no side effects so far; no coming ups and downs, it just naturally improves my mood. Also take 50mg of 5-HTP at night and it helps me to sleep like a baby. Regular exercise is also important and this helped me to move my bum and hit the gym.
zippity no blahs

this seems to be a real mood lifter and energizer,w/o the strong ups and downs of energy drinks, tripple expresso latte/chais etc.....

Just started it. Supposed to be good for the thyroid. Time will tell but so far it seems to have had a positive effect. One should do their own research on this specific nutrient.
so far so good

nothing miraculous but slight improvement in appetite control, energy level and gradual weight loss. I will continue.
