What does the R meand in RALA?

TweetWhat does the R mean in front of Alpha Lipoic Acid?

Also, what is the difference between ALA, Chromium, and Vanadyl. Would it be worth it for me to be on ALA while on low carbs dieting for a show (200-250grams)

Also, what is the does and the best brand. Thanks

From an article @ 1fast400.com

How is R-ALA different from ALA?
I have to get a little technical here in order to make the terminology meaningful. In chemistry, a compound that has four different groups attached to carbon has a plane of asymmetry. That carbon is designated “chiral”, meaning it has “handedness”. That means that the molecule can exist in two different forms that are non super-imposable mirror images of one another. Put your right palm on the back of your left hand. What do you see? Both hands have five fingers, with the same arrangement relative to the thumb and yet the thumbs point in different directions, so the hands are said to be mirror images of one another. Chiral molecules, like hands have this property. One of these isomeric molecules (called stereoisomers or enantiomers) rotates the plane of light in a machine called a polarimeter to the right and is designated dextro or +. The other isomer rotates the plane of light to the left and is called levo or -. There is another consideration when dealing with chiral molecules that places the four different substituents in order of priority. The priority is determined by convention and establishes what is called the ‘Absolute Configuration’ of the molecule. By starting with the highest priority substituent and moving in a clockwise direction to the second highest, and on to the third and fourth designates the molecule R. If you move in the opposite direction, the absolute configuration is S. Molecules in living systems generally exist in only one form. When the same molecule is synthesized, it consists of equal amounts of both forms. Commercially available alpha Lipoic acid is a synthetic product consisting of two forms, the R+ and S- isomers in equal amounts. As we said, naturally occurring Lipoic acid, the type your body makes and requires contains one form, the R-dextro or + form. This gives R-lipoic acid significantly more potency and efficacy. This is because the body recognizes R-lipoic acid and knows how to properly metabolize it, since all the key enzymes are structured to hold only the R-form of lipoic acid.

This is something easily found by searching.

Also, what is the does and the best brand. Thanks

I like 1-fast400's r-ala.... its very cheap as well.
