That is interesting, Martin.

You know the 3 main nutrients used for mitochondria support are:

acetyl-l-carnitine (studies exist for this for drug toxicity)
CoQ-10 (this is used to treat mito disorders)
lipoic acid (this is included in Dr. Ames product Juvenon)

Biotin is also suggested, as a support for the others.

Alpha lipoic is a racemic mixture and one half of it is not bioactive. There is one study on rats showing possible negative impact on the thyroid with alpha lipoic. There are no reliable studies yet on humans.

R-lipoic is a purified version, now affordable and easy to obtain.
Lower doses are therefore possible if you choose to use it.

For chemo induced damage, it is best to use the nutrients before and during the chemo. But since there are no other alternatives for after treatment, using the nutrients is all we have at this time. It is certainly worth the try. None of them have any serious tradeoffs, except for price. Using iherb.com can off set some of that too. They have many selections that are quality and affordable by good manufacturers.
