Insights & Guides

Longevity Science, Evidence and Safety

A promising biological explanation is not the same as a proven treatment. Explore the research behind longevity tests, supplements, medicines and technologies, with attention to the outcome studied, the people involved, uncertainty and safety.

This collection is educational. Inclusion does not endorse an intervention or establish that SENSES provides it. Distinguish established medical uses from experimental applications, and a change in a biomarker from an improvement in symptoms, function, disease risk or survival.

Explore individual ingredients and medicines

Supplements and Nutrients

Explore ingredient-specific guides, formulation comparisons and practical safety information before discussing a supplement with a qualified professional.

Peptides and Metabolic Medicines

Explore named peptide, metabolic-medicine and related research-compound guides, with distinctions between established indications, investigational findings and unsupported longevity claims.

Understand the research and the measurements

Biological-Age Tests

Biological age tests are growing in popularity, but what do they actually measure? Understand the science, limits, and how to use results sensibly.

Whole-Body MRI Screening

Explore whole-body MRI screening: evidence, incidental findings, preparation, safety questions and the follow-up to clarify before booking.

Microbiome Testing

Understand microbiome test reports, clinical limitations, symptom assessment and the questions to ask before changing diet or buying supplements.

Multi-Cancer Blood Tests and Screening

Distinguish established cancer-screening pathways from newer multi-cancer blood tests, and understand why earlier detection must be weighed against harms and uncertain outcomes.

Medicines, supplements and aging claims

NAD+, NMN and NR

Distinguish oral NAD precursors from intravenous NAD+, review human research outcomes and understand why a higher biomarker is not proof of rejuvenation.

Rapamycin and Metformin

Separate the legitimate medical uses of rapamycin and metformin from experimental healthy-aging use, with human trial findings, trade-offs and safety questions.

Senolytics, Spermidine and Urolithin A

Compare senolytic medicines, spermidine and urolithin A, including human trial outcomes, primary versus exploratory findings and the limits of cellular-aging claims.

Peptides for Recovery and Longevity

Understand why peptide is a chemical category rather than a guarantee of safety, and distinguish authorized medicines from unregulated recovery or anti-aging products.

Reviewing Longevity Supplements

Review a longevity supplement by asking what it is intended to do, what evidence supports that use in people, and whether it is suitable alongside your health…

Fasting and Meal Timing

Understand time-restricted eating and intermittent fasting, distinguish metabolic findings from lifespan claims, and consider nutritional adequacy and medical suitability.

Devices, oxygen, heat, cold and light

Hyperbaric Oxygen Therapy

Understand hyperbaric oxygen therapy, distinguish clinical treatment from anti-aging claims and examine what telomere studies and device safety information actually show.

Intermittent Hypoxic and Hyperoxic Training

Understand oxygen-conditioning approaches, compare different human trials and distinguish supervised research from claims that low-oxygen sessions replace exercise or reverse aging.

Sauna and Heat Therapy

Explore sauna research without turning observational findings into a life-extension promise. Understand differences between heat exposures, clinical outcomes and safe participation.

Cold-Water Immersion and Cryotherapy

Distinguish cold-water immersion, cryotherapy chambers and medical cryosurgery, and review recovery research, training trade-offs and important safety questions.

Ozone Therapy

Understand why ozone is not medical oxygen, why administration routes cannot be treated as equivalent and what evidence a longevity claim would need.

Invasive procedures and detox claims

Stem Cells and Exosomes

Distinguish established cell-based medicine and authorized research from unregulated stem-cell or exosome products marketed for rejuvenation.

IV Vitamins and Hydration

Distinguish prescribed fluids and deficiency treatment from wellness infusions, with questions about evidence, ingredients, monitoring and safer alternatives.

Plasma Exchange and Young Plasma

Separate established therapeutic plasma exchange, young-donor plasma infusions and preliminary aging-marker research before evaluating a longevity proposal.

Chelation Therapy

Understand legitimate chelation treatment, what the TACT studies found, and why a lower metal measurement does not automatically mean better cardiovascular health.

Detoxes and Cleanses

Separate commercial detox claims from medical treatment, understand cleanse risks and turn concerns about digestion, fatigue or exposure into appropriate care.
