Works amazingly as a natural replacement for thyroid medication.

It works as all tyrosine supplements. Sometimes it's a good booster but also can get you wired and anxious. I guess that depends on the state of your mind. If you're already anxious or worried - I don't recommend. It will not boost you, but get you more wired.

I always feel awful in the morning, but 30 minutes after I take it, plus coffee, feels way better!

Used as a supplement to L-tryptophan and definitely increases its effect for helping with sleep.

Fantabulous Energy

Posted by 5741836419234565606 on Jan 27, 2015

After I start taking L-tyrosine I jump out of my bed in the morning when the first alarm rings or even before that instead of pressing snooze button and slowly crawling my way out of bed with closed eyes. I can't even wait until its gets to the morning to wake up. Waking up in the morning was never been wasy before like this. This energy will continue for the rest of the day is well. Sometimes cause slight troubles sleeping though but not something to consider. An A+ supplement for anyone lacking energy due to depression or a must have supp. Side effects free. As always Jarrow formulas comes with top quality which proves by its efficacy.

I got hypothyroidism ( Hashimoto ) and I am constanty tired and a bit disorientated. So I had to try this capsules and see it it would make any differense. But sadly they dident do anthing, Im just as tired and slow as always, it was like taking placebos and they are hard to get down becouse the gel capsules get stuck and wont go down. Wont buy them again.
