Alpha Lipoic Acid 4.8 5 71 108
good for the brain I don't think there's any way to measure what Alpha Lipoic Acid is doing, if so I'd like to know. My rating is based on trust having read literature over many years and enough confidence in Swanson. Given that it's not too expensive, has little chance of negative side-effects, and due to the science, I put it high on the list of supplements to take regularly. Taking it with acetyl-l-carnitine does seem to give a mental boost for me. February 13, 2014
Better energy I take ALA as one of 3 supplements to support my liver. It is not advertised as something that affects energy, but it did mine; the extra energy was a big surprise. January 24, 2014
all time favorite I love it and taking it have a smile on my face knowing how much it dies for me , and I feel great afterwords. Thank you. January 19, 2014
Good for me I was glad to find this product at a reasonable price as I feel it is important for me to take. January 1, 2014
ALA Review Since there is no control group, it is difficult to definitively evaluate a product but it does appear tlo be supporting other supplements as it is intended to do. December 24, 2013
excellent value My Husband's cardiologist recommended he take Alpha Lipoic Acid. This product is very good at a very fair price. September 18, 2013
Excellent Antioxident I have used ALA and L-Carnitine together for over two years, and have felt noticeably better. After researching these two supplements, I learned they reportedly work synergistically to boost the antioxident levels in your system, may improve cardiovascular health, and may improve memory. I take 300 mg of ALA and 500 mg of L-Carnitine twice daily, and can certainly feel an improvement. You may need to take the ALA with food, since the acidity may cause indigestion if taken on an empty stomach. September 1, 2013
great product great price My specialist recommended this supplement and once I found it at swanson was very impressed with both the quality and the price, It's one my daily supps and I don't think I could find it anywhere else at this rate. ALA is good for a number of bodily functions and instead of suggesting why one would take it, will just say it's good quality if you decide to supplement with it. August 26, 2013
Alpha Lipoic Acid I was deficient in this area and quickly recovered from the deficiency by means of this product. August 21, 2013
Great product At my age I try to get all the help I can to stay healthy. I try to follow Dr. Oz advise, and this is a great supplement to accomplish my goal. I wouldn't be without it August 14, 2013
Amazing product Can't imagine life without Alpha Lipoic Acid. My family uses this as did I before I found the timed release version which I prefer. We think of it as our anti-ageing pill. It is considered an anti-oxidant and free-radical scavenger. It neutralizes potentially harmfull substances and converts glucose into energy. It has so many benefits that I never want to be without it. July 4, 2013
Very satisfied Very happy to find product of this quality at this price point. Have used similar for several years with great success but was much more expensive. June 17, 2013
Quality Control Problems The product is priced very good; however, in the past two bottles I purchased, I always have one or two capsols that are left open or half filled. June 10, 2013
great value Fast shipment, great value. Have only been using this for a couple months. May 5, 2013
Antioxidant for overall support Since this substance was hghly recommended by the LINUS PAULING INSTITUTE for seniors I have included it in my supplement regimen along with L-Carnitine which was also recommended in the same report. It performs some of the same effects as Vit.C and Vit.E and also helps protect and recycle these nutrients. Great for sugar metabolism, and maintaining muscle mass. April 23, 2013
Great product Heard about this product while looking for another. Decided to try this and have had wonderful results. Capsules are small and easy to swallow. I plan on never running out and will be reordering regularly. March 27, 2013
Great Stuff! I have been using ALA for years. This is the only brand that I use. It appears to do exactly what it claims to do, and I will continue to purchase it for years to come. March 26, 2013
Best price on a recommended product Best price I could find, on the product I wanted -- highly recommended March 18, 2013
Meets recommendation of our MD Alpha lipoic acid was recommended by one of our MDs. Swanson brand meets reqirements very well as do the many vitamins and supplements we use from Swanson. January 5, 2013
No changes. I have not noticed any results from this product. September 27, 2012
Like the availability of products and variety of strengths available. This one does not give me heart burn or indigestion as some alpha-lipoic acids do. August 7, 2012
excellent It helped me a lot. I combine it with L carnitine. May 26, 2012
Bad Reaction This is my 2nd attempt to review, so hope this one goes through. I used one 300mg ALA per day for 3 weeks and developed a bad reaction. Luckily I isolate supplements when trying something new. I found my reaction associated with ALA on the Internet. After stopping the ALA my symptoms gradually faded and went away after about 2 weeks. I also felt a burning sensation after swallowing which caused me to chase it with a lot of water. Obviously ALA is not for everyone. May 2, 2012
great product The vitamins came in a very timely fashion and I believe they have helped me. I trust Swanson's quality from other friends comments, and I will continue to order from them. April 30, 2012
YOUR POWER PLANTS To keep it simple, Alpha Lipoic Acid is known to work together with Acetyl-L-Carnitine to keep the body's Mitochondria, the Power Plants in each and every cell, healthy, reproducing, functioning at their peak, and from breaking down. In other words, one important aspect of Anti-Aging. Personally, I take 2 of these 300 mg. Alpha Lipoic Acid capsules with 2 Acetyl-L-Carnitine 500 mg. capsules every morning. Good stuff! I like Very Powerful, Supercharged Power Plants. April 25, 2012
