L-Carnitine 4.1 5 53 68
Energy When You Need It . I get more out of my workout now than I used to. October 27, 2013
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. October 4, 2013
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. August 26, 2013
Will Keep Buying! At age 90, I could use more energy. This product seems to be very helpful! July 14, 2013
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! July 3, 2013
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. June 27, 2013
great product I chew it up with my chewable vitamin c and wash it down with my swanson organic white tea. June 17, 2013
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. May 18, 2013
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). May 12, 2013
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! April 12, 2013
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. March 24, 2013
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. March 11, 2013
Very good stuff I take this along with peak atp to keep me focused and give me anergy March 3, 2013
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. February 21, 2013
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. February 16, 2013
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. February 7, 2013
Good Product Helps in appetite control. Not a miracle pill but there is no such thing. With proper disapline this product will help with weight loss. September 14, 2012
L-Carnitine I use this product to keep my mind energized and this is another great product from Swanson August 20, 2012
L-Carnitine Isuue is that when tablets are removed from container and placed in my pill dispenser the tablets begin to pulverize, get soft and mushy and break-up. August 15, 2012
Fat burner I take this product w/ good results for heart and liver health on a daily basis. May 27, 2012
l-carnitine-premium The products works u have to keep the cap on tight, or they will be affected-I bought on sale and was a good buy-Mkie willington Ct. May 14, 2012
Good but disintegrates These seem to be effective, but they absorb moisture too easily. May 9, 2012
Getting past Plateau? Started using this product after a long weight loss effort and hitting a plateau. Noticed increase energy which help keep the work outs going, going stronger and longer. In the end I pushed past the plateau. I did use a larger dose as most of what I read said 1000-2000mgs per day for weight loss. It also mentioned not to take after 3pm as it could upset your sleep, I didn't seem to have any sleep issues, but took my early morning and afternoon. May 8, 2012
IT WORKS FOR SURE it gives me extra boost, nice tightness in muscles, stamina and weight loss effects...i can see my body getting toned after a week of use only. will come back! April 22, 2012
Review from China Hi, I am a doctor in China. I have bought Swanson product for 4 years. My favorate product is L-carnitine, for we eat less beef and mutton in China. I have bought more than 300 bottles for myself, my families, friends, and friend's friends. Wonderful product, big price and direct mail to China, everything wonderful. I love Swansonvitamins!
