A New Blood Test Uses 8 Amino Acids to Estimate Your Biological Age
Graded Moderate — biomarker model from 9 pooled studies in over 280,000 people aged 1 to 89, yet links to disease are observational and no trial has tested the clock's clinical use.

This study suggests amino acid levels may become a simple way to track biological aging in routine bloodwork.
Scientists built a tool called AmiAge that estimates how old your body really is by measuring 18 amino acids in your blood. They then simplified it down to just 8 amino acids. People whose AmiAge was higher than their actual age tended to be frailer, had shorter telomeres, and got age-related diseases more often.
