Effects of TA-65 on telomere length, functional outcomes, and inflammation: a systematic review and meta-analysis

While TA-65 demonstrates telomerase-activating efficacy, particularly in older adults, its failure to improve functional aging metrics underscores limitations of unimodal biomarker targeting. The absence of dose-dependent toxicity or short-term oncogenic risk is notable, yet long-term carcinogenic potential remains unaddressed. Rigorous, independent trials must evaluate TA-65's chronic toxicity, telomere-independent mechanisms, and utility within multidimensional aging frameworks. Clinical application may consider older adults with immunosenescence, incorporating safety surveillance for gastrointestinal and oncological endpoints.
