What is Doctor's Best Stabilized R-Lipoic-Acid?
Alpha-lipoic acid is a sulfur-containing fatty acid that performs vitamin-like roles in the body but since the body produces lipoic-acid on its own, it is not classified as a true vitamin. It functions as a co-enzyme in the metabolism of carbohydrates and is required for synthesis of acetyl CoA, a key metabolite in the cellular process that turns glucose (blood sugar) into energy. Stabilized R-Lipoic Acid contains Na-RLA, the sodium salt of R-Lipoic acid. Pure R-Lipoic acid is a very unstable molecule that has a tendency to polymerize with exposure to heat, light, and moisture. Na-RLA is a stabilized form of R-Lipoic acid that won't degrade at high temperatures.

How does it work?
Lipoic acid is a key factor in the cellular process that metabolizes glucose for energy production. Aging is accompanied by a decreased ability of the liver to recycle ascorbic acid following oxidative stress. R-lipoic acid, has been shown after two weeks of supplementation to aged rats, to reverse the age-related impairment of ascorbic acid recycling and concentration in liver cells. Aging is also associated with oxidative stress in the brain. The brain's high rate of metabolism and its long-lived neurons make it particularly vulnerable to oxidative stress. Since lipoic-acid interrupts cellular oxidative processes in both its oxidized and reduced forms, it plays a modulatory role in the brain and nervous system.

Why should I take Doctor's Best Stabilized R-Lipoic-Acid?
An ideal antioxidant would have the ability to quench a wide variety of free radicals, to support the functioning of other antioxidants, to bind or "chelate" metal ions that can generate free radicals, to function in watery and fatty environments and to be present in a variety of tissues, cells, and extracellular spaces. Lipoic-acid meets all of these criteria and is often termed as "the universal antioxidant." As we age, our ability to synthesize alpha-lipoic acid decreases. Age also brings an accumulation of oxidized proteins that interfere with mitochondrial efficiency and Alpha-lipoic acid addresses this situation. Alpha-lipoic acid comes in two forms, designated as "R-lipoic acid" and "S-lipoic acid." R- and S- lipoic acid are enantiomer isomers--molecules that appear as mirror images of each other. R-lipoic acid is naturally synthesized by humans, animals, and plants.

Unfortunately, it has an unpleasant scent
I read the reviews and a few mentioned they were not fond of the scent. I decided to give it a try since I liked the ingredients and it seemed like it would compliment my skin type. Yes, unfortunately the scent is just way too much for me. I did not open the item or use it. Upon opening the Amazon shipping bag, I could smell it. I decided to return it. I'm disappointed, because it might be a great product. I do not want to put the brand or product down since I was unable to try it. The scent is just not for me.

An amazing Korean herbal soap!
An amazing product! With K-beauty products becoming popular worldwide, I was looking for a facial soap made with traditional Korean herbs & wild flowers etc. and ended up buying this product. Since it is a product made with traditional herbs & wild flowers, it has a strong herbal scent, but I personally liked the scent that reminded me of taking a herbal bath or herbal steam sauna. The foam was silky & sticky and after washing my face, it calmed down the redness and had a great soothing effect. If you want a medicinal soap made with traditional herbs & wild flowers that are not artificial, I highly recommend it. Although it wasn't very large size however it seemed to be made with such luxurious medicinal herbs & wild flowers. I love this product!

Smells heavenly!
- I could smell it immediately as soon as I pulled it out of the package; it smells so good! Really fresh. I think it’s the rosemary and eucalyptus oils in it maybe? - It has both a manufacturing date and an expiration date printed on the package - It has a really interesting texture (up close picture included). - It does produce a lot of lather, although it’s not a sticky lather like the listing photos show. You can absolutely tell that there are several different types of oils in the ingredients, as your skin feels very nice and moisturized after use. I’ve only been using the bar for a few days but I am a bit leery due to the number of oils in the ingredients that it may clog my pores. Nothing so far though! - Since it does create such a good lather, I can see how this bar would last you a long time. - The price is pretty in line with other snail mucin cleansers and given the ingredients I think this is a quality product so I think it’s worth giving a try!
