One of our long term members, Marlene, put up this link last week:

It illustrates the damage from antibiotics that was recently
photographed microscopically.

The supplement NAC (n-acetyl cysteine) is available over the counter, and you can consider trying it yourself. 600mg a day to start and you can increase that to 600mg 3 times a day if necessary over time.

Antibiotics damage mitochondria in cells (these mitochondria make energy for the cell so it can live and do its job properly).
Mitochondria genetically derive from old bacteria that mixed with mammals during evolution. It is a symbiotic arrangement. But since antibiotics KILL bacteria (pathogens), they also may damage or kill our needed mitochondria too.

NAC is not expensive, and can be found easily on the net.
iherb.com is only one discount vender that carries good brands of it. (NOW makes an affordable one).

There are other mito supplements too. Acetyl carnitine, R-lipoic acid stabilized, and magnesium. If you take any statins for cholesterol, these also are damaging drugs, and in that event you will also need CoQ-10.

Sometimes mito damage can come from multiple drugs you may be taking in combination. Statins are known to damage nerves.
Other antibiotics too will do this, the fluoroquinolones, Cipro, Levaquin and Avelox.
