Today's Brief
Two threads dominate today: what diet can and can't do for cellular aging, and creatine's expanding therapeutic profile. A systematic review of 27 human trials finds that calorie restriction and rapamycin lower inflammatory senescence markers while leaving the actual burden of senescent cells untouched — a critical distinction for anyone using diet to slow biological aging. UCLA research shows creatine supercharges cancer-fighting T cells, a gene therapy trial targets age reversal in the eye, and Bryan Johnson's autoimmune gastritis diagnosis offers a sobering counterpoint to aggressive optimization.

New Review Maps the Expanding Treatment Landscape for Alzheimer's Disease
A comprehensive review in Frontiers in Pharmacology surveys current and emerging Alzheimer's treatments, including lecanemab — the first anti-amyloid therapy to receive full FDA approval, cleared for patients with mild cognitive impairment or early dementia. The review covers how the field is moving from symptom management toward disease modification. If you have a family member in the early stages of Alzheimer's, this overview clarifies what now has regulatory backing versus what remains experimental.

Creatine May Give Cancer Immunotherapy a Significant Boost, UCLA Study Shows
Creatine, already a staple in many supplement stacks for muscle and cognitive performance, may also enhance the immune system's ability to fight cancer. A new UCLA study published in iScience found that creatine boosts the activity of killer T cells in both mouse models and human cells — building on prior findings from the same team. This is preclinical data, not yet a human RCT, but it adds a meaningful new dimension to creatine's already compelling biological profile.

Both metformin and proton pump inhibitors like omeprazole are among the most widely prescribed drugs — and both are associated with gradual vitamin B12 depletion that can go undetected for years. Left unchecked, low B12 can cause fatigue, peripheral nerve damage, and cognitive decline. If you take either of these drugs long-term — and many longevity-optimizers take metformin off-label — a simple, inexpensive blood test is a high-value safeguard that many doctors now recommend as standard practice.

Diet and Rapamycin Quiet Aging's Inflammatory Fire — But Can't Clear the Zombie Cells
A systematic review of 27 human trials (3,811 participants) in Ageing Research Reviews finds that calorie restriction — and calorie-restriction mimetics including rapamycin — consistently lower the circulating inflammatory proteins that senescent cells secrete (the SASP). The catch: direct markers of actual senescent cell presence, like p16 and p21, remained largely unchanged across studies, suggesting your diet is dampening the alarm without removing the underlying threat. Omega-3 fatty acids showed modest effects on SASP-related markers, though the evidence base for supplements beyond calorie restriction remains thin. The distinction matters enormously — quieting the SASP may lower disease risk and reduce inflammation, but it is not the same as reducing the burden of dysfunctional zombie cells, a job for which senolytics remain the only documented tool.

University of Pittsburgh researchers found that your metabolic state at the moment your immune system first encounters a threat leaves a durable, heritable imprint on your CD8+ killer T cells. Fed-state T cells develop more mitochondria, burn more fuel, and mount stronger immune responses for weeks afterward. This raises real questions for anyone who intermittent fasts or trains fasted — the timing of immune activation relative to meals may have consequences that persist long after the meal itself.

The Dunedin Pace of Aging clock does appear to respond to lifestyle interventions, lending some credibility to using it as a feedback tool. However, Fight Aging! argues that clocks built via machine learning have a fundamental limitation: there is little understanding of how interventions working through novel mechanisms — like clearing senescent cells or improving mitochondrial function — would register on any given clock. Treat your aging clock score as a rough signal of broad lifestyle trends, not a precise biological readout.

Peter Attia on Building Strength and Muscle for Longevity: The Full Playbook
In a rebroadcast of one of his most-requested AMAs, Peter Attia covers the fundamentals of building and preserving muscle mass as a longevity strategy — training principles, protein targets, and programming structure. Attia's framing that "the more you move, the more you're alive" captures why muscle preservation matters far beyond aesthetics: it's central to metabolic health, fall prevention, and all-cause mortality risk. Essential listening if you're structuring or auditing a resistance training program.

Can Gene Therapy Reverse Aging in Your Eyes? ER-100 Enters Early Clinical Trials
ER-100, a gene therapy that delivers Yamanaka reprogramming factors to retinal cells, has entered early-stage clinical trials with the aim of reversing age-related decline in the optic nerve — initially targeting glaucoma. Experts caution that off-target effects remain a serious concern: genes activating in unintended tissues, overexpression, and the inability to switch off expression on demand are all real risks at this stage. This is early science, but it represents the first serious application of cellular reprogramming to reverse biological aging in a human organ within a controlled trial.

Bryan Johnson, the tech entrepreneur who spends roughly $2 million annually on longevity protocols, has revealed a diagnosis of autoimmune gastritis — a condition in which the immune system attacks the stomach lining, impairing acid production and nutrient absorption. Johnson had experienced years of low iron levels before biopsies and blood tests confirmed the diagnosis. The case doesn't prove his protocols caused the condition, but it's a timely reminder that aggressive optimization cannot fully insulate against autoimmune dysfunction — and that nutrient absorption testing deserves a place in any serious longevity stack.
