Are circa 1mg doses of melatonin too wimpy to protect/enhance brain mitochondria?

"Both in vitro and in vivo, melatonin was effective to prevent
oxidative stress/nitrosative stress-induced mitochondrial
dysfunction seen in experimental models of AD, PD and HD.
These effects are seen at doses 2-3 orders of magnitude higher
than those required to affect sleep and circadian rhythms....
clinical trials employing melatonin in the range of
50-100mg/day are needed to assess its therapeutic validity in
neurodegenerative disorders."
Or, for prevention in (presumably) healthy people, maybe just 5-10 mg/day?
Just a crazy unjustified wild-ass guess.

I don't know anything about MDA, can you explain this? Thanks.

Malondialdehyde is a marker for oxidative stress. If you have higher levels of MDA (I hate their use of this acronym, as it conflicts with methylendioxyamphetamine), then it is a marker that your body is dealing with higher amounts of oxidative stress. Lowering the level of malondialdehyde indicates that your body is dealing with less oxidative stress.
