Targeting biological age with bioactive, microbiota-accessible nutritional complexes: a pilot study on healthspan extension in medically healthy adults.

Abstract

Microbiota-accessible nutritional complexes (MAC), a formulation comprising prebiotics, postbiotics, autophagy stimulators, senolytic activators, and natural probiotics, may influence systemic biomarkers and biological aging in healthy individuals. This pilot interventional study aimed to evaluate the effects of a 60-day MAC supplementation on serum biomarkers and biological age (BioAge) in medically healthy adults. Methods: Of 13 screened, 12 enrolled; 3 were excluded from the final analysis. Nine participants (five females, four males; mean age 61 ± 9.29 years) completed 60 days of daily MAC supplementation and were included in the analyses. Serum biomarkers were measured at baseline and post-intervention. BioAge was estimated using three machine-learning regressors: Support Vector Regression (SVR), Random Forest (RF), and eXtreme Gradient Boosting (XGBoost). Feature importance analysis was conducted to identify key predictors of BioAge. Results: No adverse events occurred. A significant reduction in high-sensitivity C-reactive protein (hs-CRP) levels was observed from 2.66 ± 4.65 to 0.84 ± 0.54 mg/L (-69%;
