Other than Acetylcarnitine what other orally-bioavailable Acetyl donors exist to assist in the conversion of CoA to acetyl-CoA?
This is only a guess, maybe acetic acid, ie vinegar?

Acids are effectively hydrogen salts, but the acetyl ion might be alkaline like the hydroxyl ion, making acetic acid less acidic than most? As in water, pH neutral, is a combination of hydrogen and hydroxyl, H and OH, ions?
