Anyone with weakness or exercise intolerance should try acetyl carnitine. This has proven beneficial effects in the elderly anyway and the HIV community has used it for over a decade now.

Body builders use it in high dose, but people like us may see improvements at just 250mg a day or so. (up to 2 grams if necessary in divided doses). I use Puritan's Pride form, as it it pretty affordable from them.

Carnitine enables mitochondria to use fatty acids when glucose is low. It helps transport the fatty acids across the mitochondria membranes for metabolic energy. I found it very helpful back when I was going to the gym alot, but now I don't use a gym, but still the carnitine helps with stamina and climbing stairs for me now. If I skip a day or two now, I really feel the difference!

Thanks, I took L-carnitine at one point, did not see any effects. How about acetyl carnitine is it much different??
I read that meat contains 80 mg of carnitin. No wonder after eating meat feel stronger.

Here is good brief monograph on carnitine.
Carnitine — Health Professional Fact Sheet

I find the plain l- carnitine less effective (I tried Doctor's Best) not too long ago. Something about the acetyl form seems to work better for me. (however I do notice some acidic vinegary odor sometimes from it on my skin). That is why I went back to the plain L form but I lost stamina on it.

Look up the Juvenon website, as it has lots of information on how carnitine works in the mitochondria especially for aging adults. Dr. Ames did alot of research when offering that product when it was new.

the acetyls i see on amazon are labeled Acetyl L-Carnitine . Is that the name of the good form?

yes, it is the same. I just get tired of putting that -l- in it, which is difficult on an iPhone tiny keypad.

gotcha. thanks.

My feet and leg start getting painful just by standing. Is this sign of SFN?
Does any one else has this issue please?
Thanks
