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.

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.

２カプセルでシャキッとした感じになります。やる気の出ない朝などは重宝しますね。 この価格で続けてくれますと非常に助かります。

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.
