Elysium has introduced Balance, a formulation combining its NAD+ precursor product Basis with S-equol and ergothioneine, positioned for perimenopausal and menopausal symptom relief alongside longer-term postmenopausal health. The company reports that an open-label pilot of Basis showed a significant increase in the estradiol-to-estrone ratio with reductions in hot flashes, disrupted sleep and bloating; a larger randomized placebo-controlled trial is planned. The estradiol-to-estrone ratio is an emerging marker of reproductive aging, making it a measurable target rather than a symptom-only endpoint.
Reviewers in Biology propose SIRT1 functional reserve — the remaining operational flexibility of SIRT1-dependent responses under a defined stress load — as a more meaningful measure than static SIRT1 or NAD+ levels. Total cellular NAD+ obscures compartment-specific availability, and total SIRT1 obscures the accumulation of less functional v2 and v3 isoforms with age, which may account for the modest results of supplementation trials aimed at raising these molecules.
MitoRx Therapeutics will present preclinical data at EASD 2025 on MTRX31, a small molecule that reduces body weight and fat mass in diet-induced obese mice by shifting fuel use from fat to carbohydrate oxidation rather than suppressing appetite. The company reports greater and more durable weight loss than tirzepatide at the doses tested, with lean mass preserved. All figures remain unpublished, and the study was conducted at thermoneutrality to remove cold-induced energy expenditure as a confounder.
Xella Health has integrated Oura's continuous biometric stream — sleep, heart rate variability, resting heart rate, temperature trends, recovery, activity, and menstrual-cycle indicators — with its multi-omic diagnostics and physician-guided care. The stated aim is to interpret day-to-day physiological trends against deeper molecular data across fertility, perimenopause, cardiometabolic, and hormonal health. The company claims its testing can identify more than 130 conditions specific to female biology.
Ultrahuman has released HealthEx PowerPlug, an in-app feature that retrieves a user's medical records through the TEFCA national record-sharing framework and aligns them chronologically with continuous Ring measurements including resting heart rate, heart rate variability, skin temperature and deep sleep. The tool maps 532 conditions, medications and procedures onto the same timeline as sensor data, flags lapsed follow-ups and overdue markers, and generates a clinician-ready visit summary. For longevity, the value lies in preserving multi-year continuity in data that otherwise fragments across unconnected providers.
Women's precision health platform Xella Health has integrated Oura's continuous biometric stream — sleep, heart rate variability, resting heart rate, temperature trends, activity and menstrual-cycle data — with multi-omic diagnostics and physician-led interpretation. The stated aim is to judge physiological change against an individual woman's established baseline rather than a population reference range, particularly across perimenopause. The company frames this as a route to earlier prevention, though the integration does not by itself establish causality behind observed trajectories.
Research in npj Aging identifies decline in HSF1 signaling — the transcriptional regulator governing chaperone expression and protein quality control — as a shared mechanism underlying both aging and deteriorating sleep. Weakened proteostatic capacity is positioned as a mechanistic bridge between age-related protein misfolding and the sleep fragmentation characteristic of later life. The relationship appears bidirectional, with disrupted sleep further eroding the cell's ability to maintain protein integrity.
Neurologist Dr David Dodick and gynecologist Dr Elizabeth Poynor argue that menopause should be understood as a neurological and cardiometabolic transition rather than a strictly reproductive one. Fluctuating estrogen alters brain glucose utilization and mitochondrial function while shifting fat distribution toward visceral stores and increasing insulin resistance, creating converging risks for cognition and cardiovascular health. Symptoms commonly dismissed as inevitable — brain fog, disrupted sleep, worsening migraine — may instead be early indicators of that transition.
MitoRx will present preclinical data at EASD 2026 showing that its lead candidate MTRX31 shifted fuel use from fat to carbohydrate oxidation in diet-induced obesity mice housed at thermoneutrality, producing reductions in body weight and fat mass while preserving lean mass. The company reports greater and more durable weight loss than tirzepatide at the doses tested, with structural biology evidence supporting a single defined molecular target. The compound is designed to reduce ectopic fat by restoring mitochondrial metabolism rather than suppressing appetite.
Ultrahuman has integrated electronic medical records with continuous wearable biomarkers through the HealthEx PowerPlug, placing diagnoses, medications and procedures on the same timeline as resting heart rate, heart rate variability, skin temperature and deep sleep. The feature retrieves records nationwide via the Trusted Exchange Framework and Common Agreement, flags missed follow-ups, and produces a visit summary linked to wearable data. For longevity practice, it addresses a persistent gap between episodic clinical documentation and continuous physiological monitoring.
A detailed examination of thyroid physiology addressing how symptoms are interpreted, how dysfunction is diagnosed, and how to manage patients whose laboratory values fall between clearly normal and clearly abnormal. The discussion weighs competing clinical schools of thought — conventional TSH-anchored diagnosis versus symptom-led treatment — and identifies where each is incomplete. Thyroid status governs metabolic rate, thermoregulation, cognition, and tissue repair, making accurate interpretation consequential across decades of healthspan.
Researchers at the University of Alabama at Birmingham and the University of Michigan have proposed 12 candidate aging rate indicators — molecular and physiological measures that differ consistently between normal mice and mice whose aging has been slowed by drugs, diet or genetics. Unlike biological age estimates, which record accumulated damage, these indicators are intended to register whether an organism has entered a slow-aging state in the present. If validated, they would shorten the timeline and cost of evaluating geroprotective compounds and clarify what slowed aging actually consists of.
