Ask HN: Have you taken anti-aging supplements that reduced biological age?

I am curious to hear from anyone that has tried anti aging supplements and observed a measurable reduction in their biological age as a direct result of the supplements? I am equally interested in hearing from those that tried these, or similar supplements with no measurable reduction in biological age.

For those that observed a measurable reduction in biological age:

    - What were the supplements & dosage?
    - What was the measurable improvement?

Examples of such supplements:

    Nicotinamide mononucleotide (NMN)
    Resveratrol
    Metformin
    Statin
    Alpha lipoic acid (ALA)
    Coenzyme Q10 (coQ10)
    Spermidine
    Quercetin and fisetin
    TMG (trimethylglycine or betaine)
