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.

A good product, not to be mixed with other supplements

Posted by Reviewer3196168 on Mar 20, 2010

This product is very good quality, but I recommend not taking it in conjunction with other, similar supplements. When I combine it with the other supplements, I get a headache, but when I take it alone, it has the effect of an anti-depressant, without the side-effects of prescription medication.

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.
