Rated 1 out of 5 by from Alpha Lipoic Acid 100 mg Does not work I used to take Alpha Lipoic Acid 100 mg supplement from a different store. There are certain indicators (urine) that supposed to happen while this supplement is taken. Did not happen with Swanson's version. I took exactly the same dose/potency (based on the label) as before. Makes me think about other supplements I got from Swanson.

Rated 5 out of 5 by from Dependable Quality I take ALA as a generally useful anti-oxidant, and for skin health. I appreciate being able to purchase it in a moderate dose, at a good price, from a source I trust.

Rated 3 out of 5 by from Swanson Premium Alpha Lipoic Acid I purchased this for Stomach acids and found it caused me more harm than good. It gave me heart burn and I tried it several times but had to give up on it. Thanks but not this time.

Rated 5 out of 5 by from Just Right I like this strength of Alpha Lipoic Acid as I can take it in smaller doses throughout the day.

Rated 5 out of 5 by from be careful lipoic acid can irritate mouth Don't chew capsule. Don't hold it in mouth long enough for the gelatine capsule to dissolve. Rather swallow it with a good gulp of water.

Rated 5 out of 5 by from Great Product My husband and I both take this product to promote liver health. Appears to be very effective
Date published: 2012-03-30
Rated 3 out of 5 by from Average I tried this product because the Swanson Ultra ALA was on back order and I didn't want to wait. This product seems to be the same but just diluted with more excipients. I prefer the Swanson Ultra 300mg.

Rated 5 out of 5 by from Amazing Price Im amazed at how cheap this price is. I've always found swanson's products to be good quality.

Rated 5 out of 5 by from Great Value Great quality and value for those who like taking Alpha Lipoic Acid daily.
Date published: 2011-01-10
Rated 4 out of 5 by from Great Antioxident You must remember ALA is not absorbed very good by the body. About 30% of it gets absorbed so up your dose. You can get the R version which is more expensive but also better absorbed.

Rated 5 out of 5 by from Keeping immune system up Works for me that alpha lipoic acid helps to keep my immune system up and is a complement to other vitamins.
Date published: 2010-09-05
Rated 5 out of 5 by from Amazing value The price per capsule is the lowest anywhere. It works better than the tablets I used before.

Rated 4 out of 5 by from An essential supplement I have regularly been taking 100mg daily of Alpha Lipoic acid for many years, and during this time, I have tried many brands of this supplement. Swanson Premium Alpha Lipoic Acid is an acceptable substitute to the higher-priced name brand varieties. However, I have noticed that the potency of this brand is not as effective as some other commercial products. Still, it is, on the whole, a good value for this essential nutrient.

Rated 5 out of 5 by from Great Stuff I've used the product for a good period of time and find it useful with price and availability the main benefits for choice.

Rated 5 out of 5 by from Alpha Lipoic Acid I've use this product for over 12 years. My doctor recommended it to me. Everyone tells me I look so young for my age. I'm 70 years old. Janat

Rated 5 out of 5 by from Brain booster I’ve been taking Swanson’s Alpha-lipoic acid with Acetyl-L-carnitine for a couple of years, because I read in a science magazine that clinical trails demonstrated that the combination seems to really improve memory in aging rats. A-lipoic acid may be a good way to fight cognitive decline in the aging. I take them both in middle of the day on an empty stomach. I have good recall and concentration, and want to continue to have them as I age!

Rated 5 out of 5 by from ALA is the Universal Antioxidant We love to take this supplement. It helps to detoxify the body. It is able to detoxify substances in the body that are water-soluble or fat-soluble. In doiing so, it helps protect the liver from becoming overloaded with toxins.

Rated 5 out of 5 by from Most protective supplement! Swanson's "Alpha Lipoic Acid" 100 mg. which I take 3 times daily has kept my heart strong and together with "CO-Q10" and "L-Carnitine" I have found this combination to be the best formula for more energy, and antioxidant activity available anywhere.
