    Good for non-jittery energy

    Posted by Reviewer1327608 on Sep 14, 2010

    3 grams of this stuff gives me lots of non-jittery energy that lasts for several hours. It's particularly good combined with taurine, to keep me alert yet calm.

    Very useful supplement

    Posted by Reviewer1317910 on Aug 23, 2009

    ALC is a very useful anti-aging supplement, particularly with regard to cognitive function. I haven't been taking it long enough to give definitive validation in this area. However I have noticed that gym workouts seem to be easier - I am not feeling as tired as I used to. Doctors Best make high quality, very affordable supplements. I will continue buying this product from iHerb as their pricing and service is unbeatable - especially their international postage prices.

    Helps Increase My Energy

    Posted by Reviewer1928349 on Oct 31, 2009

    I've had chronic problems with severe fatigue for 2 1/2 years. I take 30+ supplements per day. This is one of a couple that I know for sure helps with my energy. I take 2 capsules, twice per day.

    This is the best form of this supplement I have used. My energy level is up, and I feel better in general.

    These give me heartburn. It was okay as long as I only took 1-2 capsules but the maximum dose 4 capsules give me a terrible heartburn. The lower dose does not give me more energy, which was why I wanted to try this product in the first place. Sadly a disappointment.

    Good for energy

    Carnitine is also good for the brain and it can speed up the metabolic process. However, there is some research that states if overused it can actually slow down metabolism, so be watchful.
