"I bought this product locally, paying twice as much as I would have paid here. I'm not sure what the cause was but this product gave me a severe headache that lasted two days. When I say severe, I mean should I go to the emergency room severe. I would not take a product like this without consulting a doctor first. I'm not averse to trying other products from this manufacturer however.This was a stark reminder that care needs to be taken when adding new supplements."
"This product has proven reliable for helping my mind remain clear and focused during stressful occasions as well as increased my stamina. I take it on an empty stomach first thing in the morning and within a half hour my mind feels a little 'sharper' and I'm revving to get going into the day. This has also helped me feel motivated to exercise in the morning."
"I have a friend who has met Mr. Jarrows and is impressed with his ethics and commitment. Jarrows L-Tyrosine has been very effective for morning focus when taken 30 minutes before breakfast with Vitamin B6."
"This is an awesome product, makes me feel real good. The price is good. They come in capsules which I just pop open and shake in a bottle(I find this is more effective to getting the effects of tyrosine). Very good product, great price, will definitely order again."
"I feel like I have more energy to get things done, even if I'm tired, I still find I have enough energy to be able to continue, and boy do I need this right now that I have 3 grandchildren 5 days a week"
"This is a very good brand of tyrosine. Consistant results, works great. Be careful not to over do it taking tyrosine. More in this case is not better. Skip days and adjust your dosage downward once your dopamine levels are up to where they should be. If your levels are too high you will become wired and on edge, you need to skip days if this happens!"
