The article presents a compilation of recent studies on various supplements and their potential impacts on healthspan, aging, and related biomarkers. Key points include:
-
Research Focus: Studies are increasingly examining measurable outcomes such as mobility, muscle strength, and biomarkers related to aging, while human trials often yield limited and selective results.
-
Multi-Ingredient Formulations:
- V14 Longevity Blend: In a study with C. elegans (roundworms), it showed improved mobility but did not consistently extend lifespan. It seemed to influence genes involved in metabolism and immunity.
- Qualia Senolytic: After two days of supplementation, exploratory changes in biomarkers related to cellular senescence were observed, though the primary outcomes did not show significant changes.
-
Multivitamins Role: A review highlighted selective benefits for cognitive and cardiovascular outcomes but lacked consistent effects on mortality and disease risk.
-
Collagen-Derived Supplements: The Colgevity formula was associated with reduced biological age in humans and increased lifespan in preclinical tests, particularly affecting skin health.
-
NAD⁺ Research: A review indicated NAD⁺ supplements like nicotinamide riboside (NR) and NMN were generally safe and engaged biochemical targets, but their effects on physical and metabolic outcomes in humans were less clear.
-
Vascular Supplements: Certain supplements showed modest support for vascular function, but evidence for cardiovascular event reduction was limited.
-
Ergothioneine: Emerging as a potential “longevity vitamin,” low levels are linked to various health issues. Initial studies suggest benefits for cognition and sleep quality.
-
Probiotics: Probiotic strains, including one derived from a centenarian, showed promise for lifespan extension and muscle health, supporting the gut-muscle axis hypothesis.
-
Menopause and Bone Health: Two different supplements showed potential benefits in managing menopause symptoms and supporting bone health, though more studies are needed for confirmation.
-
Study Limitations: Many studies faced issues like small sample sizes, short durations, and reliance on surrogate endpoints, suggesting a need for larger, more rigorous trials.
Overall, the article underscores the promising yet variable effects of various supplements on health spans and aging markers, highlighting the need for further research to clarify these findings.
