I have been taking these supplements for about two weeks now as advised by my neurologist. Specifically, 1,000 mg l-carnitine (twice a day) and 600 mg Alpha Liopoic Acid (once a day) - both purchased from i-herb*. It is my understanding that the supplements can aid the body in the regeneration of nerve fiber.

Questions are:
1. Does this therapy work for your PN?
2. Do you have any side effects?
3. How long before you feel beneficial results?

I understand it as a hit or miss thing - sometimes the supplements help, sometimes they don't.
Interested to hear of your experience in taking the supplements.

Alpha Lipoic Acid - Doctor's Best Brand

Because of CMT, nothing aids in the regeneration of nerve fiber for those of us who have CMT. There is no cure/treatment at the present time. No magic bullet. One day they may find an answer.

Kitt is correct in that known reversal treatments for CMT are not known yet (other than some weak studies on one variant of CMT using Vit C)

However, it is rare for a neurologist to recommend supplements these days, IMO.

Alpha lipoic has been improved to r-lipoic which allows for lower doses.

The most common side effect for alpha or r-lipoic is stomach upset. But only 2 people here over the years have reported that.

Both are rather benign to take. I would start seeing effects in a month or so. Maybe longer. After six months with no effect, I think you can scrap them.

Alpha lipoic depending on doses may lower blood sugar readings. So diabetics should test blood sugar while using it.

Both supplements have long histories on PubMed around the world for being helpful for PN. (tested on diabetics).
HIV patients taking drugs for that use acetyl carnitine to minimize the PN that comes from those treatments. Also chemo.

Both supplements enhance mitochondrial functions of the cells. Your response to them, will tell your neurologist what your probable cause is, I would think.

Hello,
Switching to R-lipoic acid is easier on my stomach and if I don't take my 2000mg of Vit-C for a couple of days I can feel a let down

For a person with CMT. The Ascorbic Acid (Vitamin C) trials that are going on are for CMT1A which is the most common type of CMT. The results will not be known for several years. Some trials (in another country) for children are over and it did not work.

Just because Vitamin C is available over the counter does not mean that it is safe for a person with CMT. But if a CMTer chooses to take it in high doses, it is considered a drug. A CMTer should definitely check with their doctor before doing this as there can be side effects such as acidifying your urine and a slight chance of kidney stones which are very painful. So if a CMTer chooses to take 2000 mg or 4000 mg a day, talk to your doctor before doing this, depending on your medical history.

I use Ester C now, 500mg daily. There is no stomach affects, and I don't notice any acidic urine either. I am doing this because I am now on a fructose free diet and cannot eat fruit anymore or drink juices.

The Ester C seems very mild compared to the old regular one.

Vit C is helpful for people with arthritis.

Yes, Vitamin C is good for people for a lot of reasons. But for CMTers, not in big doses. A person with CMT should check with their doctor and go from there. Thus the Ascorbic Acid (Vitamin C) trials that they are doing for CMT1A. It would be great if there was a breakthrough and it helped our problem.

I am only addressing a person with CMT.

Thank you all for your comments...

Hello,
The reason for the Vit-C comes from reading a book by the late Dr. Pauling considering high C dosages. I don't take the virus shots and have had only a few colds in the last 15 years of Vit-C usage.

My first neurologist recommended alpha lipoic acid, vitamins C,E,B complex and a multiple vitamin. Almost a year later I am only taking 300 mg. of lipoic acid daily and occasionaly take 500 mg. of C. I can't say it has improved my neuropathy.
