friend loves it...I'm still trying it...

Posted by Reviewer2153251 on Aug 03, 2011

My friend swears by this product for her energy levels. She's noticed a major change. She has suffered from depression for years. I'm still trying it out for my energy levels.

Helpful for Concentration

Posted by wholefoods on Aug 15, 2012

I purchased this product to help my concentrate at work. I started with a low dose, 1 capsule per day and increased to 2 capsules per day on an empty stomach just after waking up. I could really tell the difference when I didn't take this product. I used the product for about 8 months and have since decided to take a break. I felt that perhaps the effectiveness was declining and I was also somewhat concerned about take an isolated amino acid supplement. I recommend this product for people dealing with dopamine deficiency and poor concentration.

I take this to combine with 5-htp for anxiety. What i got is that i am not tired any more in the morning but i didnt get any boost of energy just tirednes is decreased for like 50-60 % at the morning ai am ok now , not great but OK after 3 weeks of taking. I recomend this for some little depresive periods but not for anxiety and bigger depression. ! And i rate this with 3 stars becayse it helps with tirednes and little with mood but nothing special ! And from 5-htp i dodnt get NOTHING ! its like i drink sugar pills ! Dont buy 5-htp it doesnt help at all. Beter take Tryptophan becayse i know its working.

Good product,

Too bad it doesn't come in veggie caps :( But the effect is very noticeable unlike with other brands. Jarrow products are very good.

I'm not sure about this yet, it doesn't seem to be as strong as a tablet I used to take so am thinking of opening the capsules.

Works great

Posted by Reviewer2689129 on Dec 10, 2012

I just stopped taking Adderall XR a week ago. I use this in the morning right when I wake up with juice like it says on the bottle. I take 1,500mg a day though due the withdrawal issues. I took it every other day at first to see if I it was really working or if I was imagining it. Thankfully it wasn't my imagination. My mental fog is very tolerable on the days I take this, that's pretty amazing after stopping my medication cold turkey.
