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)
I have also found measuring and interpreting different biomarkers nontrivial.
