Glycine and N-acetylcysteine (GlyNAC) supplementation in older adults improves glutathione deficiency, oxidative stress, mitochondrial dysfunction, inflammation, insulin resistance, endothelial dysfunction, muscle strength, and cognition

For those of you who don't know, NAC and glycine are cheap OTC supplements.

NAC is a delivery vehicle for the sulfur amino acid cysteine, which oxidizes readily but does not when formulated as NAC. Cells take up NAC and convert it into cysteine.

Glycine is itself an amino acid

The results of this study show that the combination of NAC and glycine in people age 71-80 fights aging, and the results are not weak.

Since the supplements used are amino acids, that means that someone eating a higher protein diet might get similar results.

However, protein consumption among older adults is shockingly low, and the RDA for protein from health authorities is inadequate, many scientists contend.

Of course, the taboo on eating more meat doesn't help.

Even if NAC and glycine are a band-aid for low protein consumption, they can obviously help. When it comes to fighting aging, you can't wait for 100% certainty, otherwise you'll die first.

But, the FDA is trying to ban NAC.

The FDA has been trying to ban supplements for decades, but has been largely stopped by legislation.

Trying to ban NAC seems particularly insidious.

NAC may well be effective as a Covid/flu treatment.

Is that why they're trying to ban it?

In any case, NAC + glycine may increase healthspan for the elderly, conceivably even increase lifespan.
