Great product and value

Posted by iHerb Customer on Mar 08, 2007 | Verified Purchase

I use this because it seems to help stabilize my moods. I Used to take Wellbutrin for depression, and it worked well, but when I lost my insurance I had to find a lower cost alternative that would boost some of the same neurotransmitters as Wellbutrin did. This amino acid was recommended to me. It doesn't replace the effects of the Wellbutrin for me, but it does a good job. I use 1/4 teaspoon with breakfast, and sometimes with lunch as well. I like the freeform powder because it allows custom dosages, and is cheaper and absorbs very fast. This amino acid may keep you up at night, so don't take it before bed. Good luck.

Thanks for your feedback!

powder economy

Posted by iHerb Customer on Dec 18, 2007 | Verified Purchase

The cost of powder (non encapsulated) amino acids is decidedly less than the other forms. L-Tyrosine is tasteless, and, therefore, I find it very palatable and easy to take. A good deal for a high quality product.

Boosts my thyroid function

Posted by iHerb Customer on Dec 13, 2007 | Verified Purchase

I take a spoonful of this every morning along with a capsule of kelp, to insure my body has all the building blocks to make thyroid hormone. It works. When I skip it for a couple of days, on the third day I notice my eyes will feel drawn and my energy lower.

Thanks for your feedback!

Tyrosine works

Posted by iHerb Customer on Oct 11, 2007 | Verified Purchase

This product has taken away MOST of my exhaustion! I finally found something that really helps! There is no negative effect. (You need to take vitamin C with it to work properly.)

Thanks for your feedback!

Tyrosine in Bulk

This amino acid I notice improved alertness, arousal, and mood, and slight loss in appetite

Thanks for your feedback!

Best powder I have found

Posted by iHerb Customer on Dec 18, 2011 | Verified Purchase

This product offers very good value and is easy to take. Some powders do not dissolve in water leaving a gritty residue. NOT this one. Dissolves into a milky powder and is tasteless.

Thanks for your feedback!

improved alertness

Posted by iHerb Customer on Feb 19, 2009 | Verified Purchase

I've been taking 100 mg phenylalanine + 100 mg tyrosine twice daily to help balance my neurotransmitter levels and it's helped me feel much more alert during the day.

Thanks for your feedback!

I would recommend this product

Posted by iHerb Customer on Nov 13, 2009 | Verified Purchase

Taking this for depression. In combination with exercise, other therapies and SAMe, it has evened out my mood.

Thanks for your feedback!

Great product, Great Price

Posted by iHerb Customer on Mar 07, 2009 | Verified Purchase

I've tried a few different L-Tyrosine products with mediocre results(all capsules); since using Tyrosine Powder I am able to make my own specific dose; the powder also feels like it is not only more effective but it also kicks in quicker. The powder form is definitely the way to go with this supplement(among others), and I plan to continue buying this product monthly to continue maintenance. Be sure to mix it with some juices(preferably OJ) in the morning before you eat anything; it will increase the effectiveness.

Thanks for your feedback!

love it!

Makes me feel great. Concentration at work, cravings are gone and feel happier in general. It's an amazing product and not expensive.

Thanks for your feedback!
