hard to say i guess. they are both good but NA-R-ALA has many many many functions. but at what point do these anti oxidents become pro oxidents is a good question that was brought up by someone in another thread.
also there are interactions with ALA and thyroid medicine mainly t4. so depends on how you look at it.

Summary - We have studied the effects of N-acetylcysteine which is thought to have antioxidant properties, on the susceptibility of low-density lipoprotein to oxidation and on whole-blood glutathione concentrations in six healthy volunteers.
N-acetylcysteine was given orally in a dosage of at 1.2 g per day for 4 weeks, followed by 2.4 g per day for a further two weeks. The susceptibility of low-density lipoprotein toin vitro Cu2+-oxidation was determined by continuously measuring the formation of conjugated dienes. Whole-blood concentrations of reduced and oxidized glutathione were also determined.
N-acetylcysteine had no effect on the susceptibility of LDL to oxidation. Concentrations of vitamin E in the serum and in low-density lipoprotein were not changed. Compared with controls the concentration of glutathione in N-acetylcysteine treated subjects was reduced (?48 %) and the concentration of oxidized glutathione was higher (+80%). The GSH/GSSG-ratio, a marker of oxidative stress was 83 % lower.
The results do not support the supposed antioxidative action of N-acetylcysteine. It seems more likely that N-acetylcysteine acts as a pro-oxidant in the dosage used.

NAC as a pro oxidant... wut? This does not bode well for all of us using this for PH cycles.
Now i'm gonna have to start looking through more studies to check oxidant status.

NAC for a PH cycle is fine due to supposed increased glutathione levels in the liver from the AAS reducing them.
itll serve its function.. i wouldnt worry there. the more stress, the more training, the more eating, the more antioxidents you will likely need

Interesting... I take Alcar at 2 grams daily, and I'm using NAC as a substitute for Na-Rala, until I can get my hands on some more.

i use them both.. but can someone enlighten me on the issues of synthroid t4, and ala? I use 100mcg of T4 in the morning, and also take 200mg R-ala about an hour later.
Im worried/curious now.

The influence of alpha-lipoic acid (LA, thioctic acid, CAS 62-46-4) on thyroid hormone metabolism and serum lipid-, protein- and glucose levels was investigated. In the first setup of experiments administration of LA together with thyroxine (T4) for 9 days suppressed the T4 induced increase of T3 generation by 56%. This suppression was similar to that affected by 6-propylthiouracil (54%). LA or T4 alone did not affect the cholesterol level, but together they led to a reduction. LA decreased the triglyceride level by 45%; the decrease induced by T4 or LA plus T4 was not significant. Total protein and albumin levels decreased by LA plus T4 treatment when compared to the LA control. The slight increase in glucose level by LA or T4 alone was not observed when they were administered together. In the second setup of experiments the administration of T4 for 22 days increased the serum T3 level 3-fold. When LA was combined with T4 and the treatment continued, the T3 production decreased by 22%. T4 reduced cholesterol level by 30%, and LA plus T4 further reduced it by 47%. The triglycerides were not affected. A moderate decrease in total protein was observed after treatment with T4 plus LA; T4 and LA plus T4 decreased the albumin level. The decrease in serum glucose by T4 recovers by LA treatment. These results demonstrate that LA interferes with the production of T3 from T4 when it is co-administered with T4. The elevated level of T3, after T4 administration, is reduced by treatment with LA.(ABSTRACT TRUNCATED AT 250 WORDS)

i dont know about t3, but im sure it would have been specific.
i wouldnt take too much carnitine with t3, as they deplete eachother, when ones high the other drops (probably due to energy usage). But even carnitine has been used to reverse hyperthyroidism to a degree.
but im less worried about that as the functions for fat burning seem to correlate well with use.
t3 depletes carnitine. probably because carnitine is used to activate fats to burn for beta oxidation which happens at a quick rate for fuel usage. theres an amount i would say you should stop at but off hand i wouldnt know. i think 2g is the limit IMO, dont need more then that.

what you want is just enough to be used for fat oxidation and no more where it would increase the chance to lower t3 levels.
that why i use no more then 500-2000mg per day.

Thanks for posting those studies, after reading those and a couple others, my general understanding is that carnitines use in hyperthyroidism is through two different mechanisms. Oral carnitine administration will reduce the symptoms (not necessarily the actual disease) of hyperthyroidism by replenishing the bodies carnitine stores once they have been depleted by excess circulating T3/T4. Beyond that it seems carnitine has a slight regulatory effect on T3/T4 entrance into the cell nucleus and/or cytoplasm (peripheral antagonism?) of certain tissues, the mechanism of which I could not find so anything I say in that regard will be useless lol.
What I take from that is that it is safe to use carnitine under a euthyroid condition as long as it is not in great excess, otherwise we would have all sorts of people going hypothyroid with the mass use of carnitine, and that in order to prevent hyperthyroid symptoms while taking T3 on a scale that will amplify fatloss, it is a good idea to supplement with carnitine.
Sorry if that was already apparent to everyone, I just gotta say it myself sometimes before it really sinks in.
