Rated 5 out of 5 by from Great deal ! I ordered this item for myself. But since I got an item for free, I gave the other to my daughter. I feel more energy throughout the day instead of the dragging feeling I felt around 3 pm. This product works great !

Rated 5 out of 5 by from A Great Fitness Product. The L-Carnitine is a product that I have been taking for several years now. I am a certified Personal Trainer. I take this supplement as part of my daily workout routine. Taken after a workout this product is very effective for anyone who wants to maintain a muscle-toned body.

Rated 5 out of 5 by from Energy When You Need It . I get more out of my workout now than I used to.
Date published: 2013-10-27
Rated 4 out of 5 by from Reason about "breakdowon" problem I just want to say, the reason why pills will breakdown when we take them out from the original bottle should be the humidity. Maybe your place is too wet and without desiccant the pills will have problems. It never happens in a dry place like ours.

Rated 2 out of 5 by from CHOOSE A DIFFERENT FORM L-Carnitine is a great and useful, valuable Amino Acid which I have read about and used since around 1972 for heart health / fat burning / energy. To me, this is a good news / bad news situation. I am totally a fan of L-Carnitine. I am totally in favor of using it, which I do. That's the good news. The bad news is that L-Carnitine is very hygroscopic and difficult to manufacture into tablets or capsules that remain user-friendly in spite of the addition of desiccant packets in the bottles with the pills. It has been my experience that the tablets become moist, sticky, and crumbly, making them messy and difficult to handle and swallow. So I take my L-Carnitine in liquid form, which works great for me. Personally, I like to take 2 grams of L-Carnitine, and I just don't want to deal with having to mess with 4 of these tablets every day, especially when I have options. I do recommend taking L-Carnitine, just choose a different form.

Rated 5 out of 5 by from Best Belly Buster! This is the best for belly fat loss. I lost 2" in the first 4 months! Effective and economical! I will definitely not run out of this!
Date published: 2013-07-03
Rated 3 out of 5 by from Read before buying I like to keep my vitamins in a weekly pill container and for some reason this product starts to breakdown and "dissolve" after it is out of it's original bottle after a few days. I think the product itself it good, but you must keep it in it's original bottle and remember to take it everyday.

Rated 5 out of 5 by from great product I chew it up with my chewable vitamin c and wash it down with my swanson organic white tea.

Rated 3 out of 5 by from Energy but hurt my stomach They gave me a lot of energy. I get up very early and these almost negated the need for coffee. I loved how energized I felt. But they also really bothered my stomach. It would hurt well into the evening and I felt miserable. I finally stopped taking them.

Rated 4 out of 5 by from Recommend strongly with qualifications Have taken this suppliment for years. This brand was reviewed by consumer labs and reassured me that I was getting what I paid for without any contaminents! The tablets are extremely hydrophilic, so keep them in the bottle and away from water (bathroom steam/ kitchen tea kettle).
Date published: 2013-05-12
Rated 3 out of 5 by from Great Value! My nutritionist recommended this. It seems to have some effect but the jury is still out. However, the value can't be beat anywhere!

Rated 5 out of 5 by from L-Carnitine from Swanson met goals L-Carnitine at 500mg/capsule from Swanson allows me to readily measure out the amount of L-Carnitine I wish to use and meets my goals for the expected results. I anticipate reordering to continue my plans for the supplement. I appreciated that the bottle came well filled as is sometimes not the case and you get large bottles with very few capsules or pills. Such large bottles take up shelf space but are quickly emptied.

Rated 3 out of 5 by from If improve the capsule I switched to SW brand due to save the cost from popular vitamin brand one. Effectiveness is not sure but capsule will be damage after opened the bottle in a few months. As normally kept in dried not sunshine spots such as a drawers but it always happened. I hope SW will improve the capsules.

Rated 4 out of 5 by from L-carnitine I have been taking one tablet per day for the past month or so. I seem to have more energy now. I am working out and it seems to help with over all body toning.

Rated 4 out of 5 by from L-Carnitine at a great price L-Carnitine is a great amino acid for fat burning. Some reports in the literature at increasing testosterone receptors sites. I did not notice much.
Date published: 2013-02-16
Rated 5 out of 5 by from Energy Booster! I run avidly and when I started taking L-Carnatine I noticed I had more energy. When I would get to the end of my run I still had energy to turn on the intensity and sprint it out! Also noticed some improvements in my skin and fat reduction around the waistline. Only draw back is that the pill deteriorates if left out in the open. Take immediately after taking out of the bottle or make sure to put in some sort of airtight container if taking with you for later consumption.
