From cell experiments to clinical benefit
Senescent cells and their signalling are studied in relation to ageing and disease. Effects in cell cultures or animals cannot be translated directly into effectiveness and safety in people.
A small early study of dasatinib together with quercetin in pulmonary fibrosis is one example of clinical research. It does not establish the benefits of quercetin alone, fisetin or general longevity protocols in healthy people.
What can COMT and methylation tell us?
COMT is involved in the metabolism of certain catechol compounds. Biochemical relationships and genetic variants are not sufficient to classify a person’s entire metabolism as fast or slow.
There is no generally validated routine in which a COMT or MTHFR result alone determines the benefit, risk or dose of a senolytic supplement. Medicines, medical conditions and the actual product also matter.
Questions before use
Ask about human studies, the relevant dose and population, known adverse effects and medicine interactions. Supplements can be biologically active even when marketed as natural.
A clinical discussion can help distinguish a research finding from established care. This article is not a dosing or treatment protocol.
