Converts to L-Dopa

Posted by StarFire on Nov 15, 2014

Purchased at iHerb

In some people, may cause anxiety, restlessness and rapid heart rate! (See norepinephrine) One cap in the morning before eating is plenty for me! This converts to L-Dopa (rate limited by your own enzymes) and then to other catecholamines. My experience - calmer and more positive - (better thyroid function?) ... more energy! It also seems that I need to take occasional breaks from this to regain the best effects.

Helpful for Concentration

Posted by wholefoods on Aug 15, 2012

Purchased at iHerb

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.

Works but....

Posted by Reviewer2169605 on Jul 27, 2014

Purchased at iHerb

These have definitely helped to regulate my thyroid, the ideal dose for me is 1.5 caps per day. However, as they are in a non-vegetarian cap, and I am allergic to animal products, I have to open the cap into juice, so will probably switch next when I run out.
