  1. Repost of an ALA article I found

    I found this article on Freaky Muscle and thought some of you would be interested in it. It is a good read just alittle long

    Putting the myth of ALA into reality

    By: FONZ&nbsp;

    ALA &nbsp;VS. R-ALA&nbsp;&nbsp;

    The latest controversial topic surrounding Alpha-lipoic Acid is the potency of the two known variants. This pertains to the newest variant; R-ALA, in comparison to racemic(or normal) ALA. This latter racemic ALA is a combination of R-ALA and S-ALA, normally found in a 50/50 split in common brand name ALA supplements.

    In order to uncover which of the two was truly the better one, I decided to measure each ALA’s impact on blood glucose for a specific meal, and compare the results. As we all pretty much know by now, ALA increases the ability of the body to store glucose in the form of glycogen and also oxidize un-needed glucose for energy. So in effect, whichever one of the two versions of ALA in my experiment gave the smallest blood glucose reading after a specific meal, was, the one which gave the user the best results in regards to glucose disposal and glucose up-take into the muscles. Fairly simple concept.

    I bought 300 100mg R-ALA caps from AF( and 2000 100mg caps from Kilosports (

    These are the respective LOT numbers

    AF: Lot # C06310 Exp: 06/04 (all three bottles)

    Kilosports: Lot # C07351 (Both bottles)

    What the analysis entailed involved performing a comparative experiment regarding the impact of a specific meal + different quantities of R-ALA and racemic ALA over a week. This latter time-frame would I believe be sufficient to factor out any inconsistencies, and also be a long enough time period to give an objective enough frame of reference in regards to the performance of both versions of ALA.

    I performed my experiment with my blood glucose meter (Glucometer) called Gluco-trend 2 with the Softclix system. The serial number of my Glucotrend 2 is GH02114809 and the type number is: 1861964 .

    I also purchased a separate glucometer at CVS to back-up the results obtained by my Glucotrend 2 blood glucose monitor. If at any time during my experiment, the values of the CVS blood glucose monitor and those of my Glucotrend 2 blood glucose monitor, were off by more than 10% I’d nullify the specific

    attempt at measuring the BG response by the given meal. This was not nice for my fingers. Having to use the lancet 10+ times/day hurt like hell….. Anyways,

    The serial number of my CVS BG monitor is: 6429796 ,and the lot number of my glucose testing strips was: EB271A1 Exp: 23/ Jan/03

    All measurements were done in the AM and/or anytime I hadn’t eaten for 12hrs, as there is NO FOOD present in the stomach after 12hrs, liver glycogen is empty, and BG levels are lowest. This is the BEST time to measure blood glucose fluctuations.

    In fact, the GTT test is best performed in the AM on an empty stomach(Ask your doctor, he will verify this) (GTT=Glucose Tolerance test). Values for the blood glucose will be given according to the American system: i.e. mg/dl .

    This is the structure of each daily measurement.

    Meal (N) N = 1,2,3……..21

    1. Take initial BG(Blood glucose) measurement

    2. Consume a SPECIFIC food.

    (I'll give the exact macro-nutrients)

    3. Take the R-ALA or racemic ALA( X number of mg)

    4. and 5 and 6. Measure BG(Blood Glucose) levels at the 1 hr, 2hr, and 3hr mark.

    So, an example with numbers would be:

    Meal 20 400mg ALA + complex(Slow GI) Carbs

    Meal: 340 1g 34g 50g (1.0L milk)

    BG(Initial): 72mg/dl (Blood glucose reading at the time of eating)

    BG(T+1): 99mg/dl (Blood glucose reading after 1hr)

    BG(T+2): 93mg/dl (Blood glucose reading after 2hrs)

    BG(T+3): 80mg/dl (Blood glucose reading after 3hrs)

    (THE ABOVE IS JUST AN EXAMPLE). The numbers are completely fictitious.

    My statistics(Body composition), in case anybody is wondering are 190lbs at roughly 9%, at a height of 5“9(174cms). I am a 23 y.o. white male. My diet during this past week was composed of 3000Kcal/day, on a rough 60% Carbs, 30% protein, 10% fat diet. In other words a typical high-carb maintenance diet for me.

    COMPLEX CARB ANALYSIS: (Carbs = 108g)

    400mg ALA+R-ALA:

    (Area under curve ALA): 0.5(1)(26)+20(1)+(0.5)(6)+20 = 56 units squared.

    (Area under curve R-ALA): 10 + 5 + 10 + 2 + 6 = 33 units squared.

    600mg ALA+R-ALA:

    (Area under curve ALA): 19 + 6 + 16 + 4 + 1 = 46 units squared

    (Area under curve R-ALA): 8.5 + 3 + 11 + 3 + 5 = 30.5 units squared

    800mg ALA+R-ALA:

    (Area under curve ALA): 0.5(1)(23)+(0.5)(11)+1(12)+ 11 = 40 units squared.

    (Area under curve R-ALA): 10 + 10 + 5 + 1 + 4 = 30 units squared

    1000mg ALA:

    (Area under curve): 0.5(1)(19)+15+2+2+0.5(14)= 35.5 units squared

    HI-CARB ANALYSIS ( Carbs = 280g)

    2000mg R-ALA:

    (Area under the curve): 10 + 9.5 + 20 +12 + 17 = 68.5 units squared

    2000mg ALA:

    (Area under the curve): 12.5 + 50 + 28 = 90.5 units squared

    3000mg ALA:

    (Area under the curve): 10 + 20 + 12.5 + 16 + 13 = 71.5 units squared


    Carbs= 108g(All meals where exactly the same)

    ALA = 400mg, Area = 56 units squared(Take as initial)

    ALA = 600mg, Area = 46 units squared(Difference: -10 units squared(17.86%))

    ALA = 800mg, Area = 40 units squared(Difference: -16 units squared(28.57%))

    ALA = 1000mg, Area = 35.5 units squared(Difference: -20.5 units squared(36.61%))

    R-ALA=400mg, Area = 33 units squared

    R-ALA=600mg, Area = 30.5 units squared(Difference: -2.5 units squared(7.58%))

    R-ALA=800mg, Area = 30 units squared(Difference: -3 units squared(9.09%)

    From the above table, one can see that as ALA intake is increased for the given meal (Containing 108g carbs as specified), the area under the blood glucose curve decreases. This is indicative of the extra ALA having an effect on glucose up-take and oxidation. From looking at the table, one can see a pattern; namely, that as the ALA dosage is increased for the particular amount of carbs, the area under the blood glucose gets smaller in SMALLER increments. This is what is referred to as a decreasing numerical series. Elaborating the series, one can extrapolate the best dosage of racemic ALA per gram of carbohydrates.

    Series(1): = 56……..46……..40…….35.5….

    Difference: = 10……..6……. 4.5……….……..approaches 0.

    From this, we can easily approximate the next difference between areas

    to be 2 and then 0.

    So, the series becomes:

    Series(1): 56(400ALA)…..46(600ALA)…..40(8 00 ALA)…..35.5(1000ALA)…33.5(1200 ALA)…..

    So, from this, one can see that the dosage of ALA that would maximize its glucose up-take enhancing effects and glucose disposing effects, while minimizing any over-dosing(The ALA would simply be excreted, with your hard earned money),

    would be 1200mg ALA per 108g carbs or 11.11mg ALA/ (g) carbs.

    From the table above, one can also see that as the amount of R-ALA is increased in relation to a given specific carb meal(C=108g), the area under curve does indeed gets smaller, but only slightly. One can therefore surmise that over the amount of

    400mg per 108g carbs there isn’t really any point in taking more as the area under the blood glucose curve will decrease negligibly, and you’d basically be throwing your R-ALA away. That would put the optimal dosage of R-ALA per (g) of carbs at 3.70mg R-ALA per gram of carbs. This makes R-ALA 3X as powerful as racemic ALA if the carb meal &lt;108g (3.7mg/g carbs compared to 11.11mg/g carbs) (Remember carbs &lt; 108g) If you want to nit-pick, yes, you can go as high as 600-800mg of R-ALA per 108g carbs, but you’ll only get a 7.5-9% increase in effectiveness(See the table). Hardly efficient or cost effective if you ask me.

    Now, as you may have noticed I have also included a high-carb section w/ ALA and R-ALA. This section was to test if there was an upper limit to ALA’s effectiveness. What I asked myself, was wether there was a physiological point where ALA just stopped working(i.e. Too much glucose entering the blood-stream.).

    I’ll re-post the data:

    Carbohydrates = 280g(At once)

    2000mg R-ALA:

    (Area under the curve): 10 + 9.5 + 20 +12 + 17 = 68.5 units squared

    2000mg ALA:

    (Area under the curve): 12.5 + 50 + 28 = 90.5 units squared

    3000mg ALA:

    (Area under the curve): 10 + 20 + 12.5 + 16 + 13 = 71.5 units squared

    Ok, here is the interesting part……as extrapolated above, R-ALA is about 3X more powerful than ALA at stimulating glucose up-take and disposal FOR A SPECIFIC AMOUNT OF CARBS. Very important this. From the numbers above, one can easily see that 2000mgs R-ALA was about as effective as 3100mg ALA(I extrapolated) in keeping the blood glucose response curve under control, making it only 55% stronger than ALA not 3X stronger.

    Interesting. We have just discovered something of importance. R-ALA(And similiarly ALA to a smaller degree) works best if carb intake during the day is comprised of SMALLER carb meals not one big one.


    Having completed the experiment I can safely say I think I have the dosages of R-ALA and racemic ALA pretty well figured out. These are: 11.11mg of racemic ALA per gram(g) of carbohydrates, and 3.7mg of R-ALA per gram(g) of carbohydrates; AS LONG AS the carb content of the meal is kept &lt; 108g. If the carb content of the meal goes beyond 108g the R-ALA loses effectiveness at an ever increasing rate, but still manages to be 55% more effective(mg per mg) than racemic after a single 280g carb load. To use an analogy, R-ALA is like a scalpel while ALA is like a kitchen Knife. They will both work, but for cutting I would go with R-ALA, and for bulking I’d go with racemic ALA because of the cost. <!--Signature-->

  5. Beautiful post. I was actually thinking of doing this myself...but now there's no need to..

  6. I have read a post regarding the possibility of polymerization when R-ALA is stored at or above 25C/77F. Does anyone have the organic mechanism for this reaction?

  7. Good stuff. Great article.

  8. EDIT: Whoops.. was thinking Mattew D did the study. Didn't read the title
