Rated 5 out of 5 by from All of my other supps seem to work better! Happy to be taking this one - FINALLY! I really thought I was doing everything right with respect to my well being & good health! Well, I was missing this one for sure! I really do feel more energized, probably because of the combination of supps that I take! Just thankful my friend recommended this one! Look this one up for yourself! Thanks again Swanson!

Rated 5 out of 5 by from One of my Favorites! This is one of my Favorite products because it's MY belief that it makes many of the other things I take to be more potent - that is, I believe that my body uses the other things more effectively. I choose the 300 mg so that I take 1 in AM with morning vits/mins/herbs, and I take 1 in PM with evening vitgs/mins/herbs. I prefer that, rather than taking 1 600 mg capsule at 1 point in the day.

Rated 5 out of 5 by from Alpha Lipoic Acid I have been taking this for quite a while now. I have read many things about it and I think it is worth it for me to take it.

Rated 1 out of 5 by from Broken capsules There are many broken capsules. When you tilt the bottle to get a capsule, lot of white powder spills in the hand.

Rated 5 out of 5 by from Swanson's Alpha Lipoic Acid GREAT supplement, antioxidant and detox! I take it with L-Glutathione (also available here at Swanson), for a one-two Detox punch. It can be pricey, but.... just wait for the sale or when it's on BOGO and stock up!

Rated 2 out of 5 by from inadequate quality control Many of the pills in each bottle do not contain the full 300 mg of alpha lipoic acid
Date published: 2014-09-18
Rated 4 out of 5 by from great value very effective and valuable for anybody doing cleanse, detoxification or for every day support to replenish your body. I recommend it to many of our friends, the price is great and easy to take.

Rated 5 out of 5 by from Alpha Lipoic Acid I'm not sure what to expect from this that would be noticeable, hence the lower effectiveness rating. Otherwise, a good deal.

Rated 5 out of 5 by from great antioxidant if you want to delay the effects of aging, this is a great supplement to take. i'm 72 years old and i can still perform very well at a physically demanding industrial housekeeping job. that's thanks to this product which i've been takiing for 2 decades.

Rated 5 out of 5 by from Important supplement We have been taking this product for many years. An important companion to CoQ10.
Date published: 2014-04-30
Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Good for me I was glad to find this product at a reasonable price as I feel it is important for me to take.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from excellent value My Husband's cardiologist recommended he take Alpha Lipoic Acid. This product is very good at a very fair price.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
Date published: 2013-08-26
Rated 5 out of 5 by from Alpha Lipoic Acid I was deficient in this area and quickly recovered from the deficiency by means of this product.
Date published: 2013-08-21
Rated 5 out of 5 by from 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
