Today's Brief
Today's issue centers on a clarifying theme: biological age is real, measurable, and increasingly modifiable. Our must-read examines the multiomics profile of María Branyas Morera — the world's oldest verified person — whose cells tested decades younger than her birth certificate. A 51-trial meta-analysis shows metformin, semaglutide, and anti-TNF drugs are already moving those same biological clocks, while the supplements section takes a hard look at the NAD+ IV craze and what chlorella can actually do for your LDL — if you respond to it.

Blocking CD38 Does Not Just Boost NAD+ — It Silences the mTOR Aging Pathway in Blood Stem Cells
Researchers discovered that inhibiting the CD38 enzyme preserves adult human hematopoietic stem cells not by simply raising NAD+ levels — as had been assumed — but by directly suppressing the mTOR pathway, forcing cells into protective metabolic hibernation. For anyone taking NMN or NR to support NAD+ biology, this reshapes the picture: the real mechanism may be upstream of NAD+ itself, through the same longevity pathway targeted by rapamycin. The result points toward CD38 inhibitors as a potential complement to existing NAD+ and mTOR protocols.

Vitamin D and Omega-3 Taken Together Measurably Slow the Epigenetic Clock, New Data Shows
New findings reported by DSM-Firmenich confirm that combining vitamin D and omega-3 supplementation slows biological aging markers in ways that either supplement alone may not match, with benefits extending to cardiovascular and bone health endpoints. If you are already taking one but not both, the combination appears to produce synergistic effects on epigenetic age — making this the evidence-backed case for the most foundational dual-supplement stack in the longevity toolkit.

In the Cotswolds, women are gathering for NAD+ and prosecco parties — social events built around celebrity-endorsed anti-aging IV drip treatments. Even the physicians administering the drips acknowledge that longevity studies for IV NAD+ are still underway and that making bold efficacy claims is not currently supported by data. If you are weighing the cost of IV NAD+ therapy, the social connection may be the clearest documented benefit for now — the biological case remains genuinely unresolved.

Chlorella's average LDL reduction of 8 mg/dL conceals a stark biological divide: some individuals see dramatic 25+ mg/dL drops while others see zero effect — and the difference is testable. Aviado's analysis explains that chlorella is not a universal superfood; it is a targeted cardiovascular intervention that either works for your biology or does not. The protocol is straightforward: take 3,000 to 5,000 mg of broken cell wall chlorella daily with meals, baseline your LDL and high-sensitivity CRP, and retest at 8 weeks — that data tells you everything.

The World's Oldest Person's Cells Were Biologically Decades Younger Than Her Birth Certificate
Maria Branyas Morera died at 117 years and 168 days — but a multiomics study published in Cell Reports Medicine found that her biological markers lagged far behind her chronological age, meaning her cells were not operating like those of a 117-year-old. Researchers identified specific epigenetic, proteomic, and metabolic signatures that may explain exceptional lifespan — the kind of blueprint longevity scientists have been searching for. For health optimizers, the key insight is this: extreme longevity is not random luck; it has a measurable biological signature, and some of those markers are already trackable in your own healthspan monitoring. This is the most complete data portrait of a supercentenarian ever assembled.

A sweeping analysis of 51 clinical trials found that metformin, semaglutide, and anti-TNF therapies each significantly reduced biological age across all 16 tested epigenetic biomarkers — raising the possibility that drugs already prescribed for diabetes, obesity, and inflammation may function as anti-aging interventions. Researchers cautioned that most results derive from disease populations, so translation to healthy longevity seekers still requires dedicated trials. Even so, the breadth of the epigenetic signal across three entirely different drug classes is striking and will accelerate the design of purpose-built longevity trials.

A Singapore team challenged the dominant assumption behind anti-aging drug discovery: that reversing all age-related gene expression changes is the goal. Some of those changes, they found, are protective — and treating them as problems to fix was generating flawed leads. By mapping worm aging transcriptomes into functional clusters and cross-referencing them against a human drug-response database, the team identified seven compounds that genuinely extended lifespan. The methodology may be the real story here — a smarter filter that could clean up a notoriously noisy anti-aging drug pipeline.

From Oslo Floating Saunas to Clinical Trials: Science Is Taking Heat Therapy for Mental Health Seriously
What began as a wellness trend in Nordic sauna culture is entering formal clinical medicine, with researchers now running controlled trials on whether whole-body heat exposure can meaningfully improve depression and anxiety — not just through social bonding, but through distinct physiological mechanisms. If trial results confirm early signals, heat therapy could join the short list of low-cost, broadly accessible mental health interventions with simultaneous cardiovascular longevity benefits. For longevity enthusiasts already using saunas for heart health, the mental health upside may be a significantly underappreciated bonus.

Lilly and Novo Nordisk Present Data Positioning GLP-1s as Longevity Drugs, Not Just Weight Loss Pills
At a major conference, both Eli Lilly and Novo Nordisk presented evidence that GLP-1 receptor agonists support healthy aging well beyond metabolic benefits. Novo's data linked semaglutide specifically to lower mortality, better physical function, and modeled gains in life expectancy — framing class-level evidence as a foundation for broader longevity claims. This is a coordinated pharmaceutical push to reposition GLP-1s as longevity medicines, and the regulatory and prescribing implications — if the data holds — are substantial.

Longevity biotech Loyal received FDA concurrence for a second clinical trial targeting healthy lifespan extension in dogs — now the largest veterinary trial in history. Beyond canine health, this matters for human longevity research: dogs share key aging biology with humans, and FDA-validated lifespan extension data in a large mammal creates a critical stepping stone toward human drug approval pathways. Loyal is quietly building the most rigorous longevity drug evidence base outside of human trials.
