Cutting through longevity hype. Evidence-based healthspan, decoded daily. No supplements to sell, just what the research actually says.

You've heard these 5 longevity claims a hundred times.

The actual research says something different about every one — and one is tied to a higher death rate, not a lower one.

What the studies really show:

[Vexis Health @VexisHealth]

@dr_ericberg The gut-brain axis is real. But "fix your gut to fix depression" runs ahead of the evidence: human data is mostly association, the causal studies are in rodents, and the link runs both ways. Gut care can be an adjunct, not a replacement for real mental health care.

@hubermanlab @AbudBakri What to tell them: "confirmed clean" fixes purity, not the evidence. Epitalon rests on one non-randomized Russian program (Khavinson), no independent RCTs. BPC-157 has ~3 tiny pilots and was FDA-flagged in 2023. Bottom line: nobody knows if either is safe long-term or works.

@fmfclips Real RCT, and omega-3 is cheap and low-risk, so worth it (DO-HEALTH). Honest caveat: these are epigenetic CLOCKS, biomarkers of aging, not proven added years. And the 61% cancer drop was a secondary endpoint, not the primary. A promising signal to watch, not settled.

@ThorTorrens Real effect: alcohol does hit harder at 40 than 20. But not from vitamin A. It's mostly less body water (higher blood alcohol per drink) and slower liver enzymes (ADH/ALDH). If anything, chronic drinking DEPLETES liver vitamin A, the opposite of the claim. (Nutrients, 2012)

@HealthyAlfred Real rabbit study, and the animal data is interesting. But that's the catch: it's animal. In humans BPC-157 has ~3 tiny pilot trials (2 to 16 people, no controls), none for bone, and the FDA flagged it in 2023. Human safety is unknown. "I take it daily" is the leap.

@ThorTorrens All true, and reversible. Creatine downregulates AGAT, yes. That’s normal end-product feedback, not dependency. Stop supplementing and AGAT recovers fully within weeks. Your body doesn’t “forget” how to make creatine. This is homeostasis, not harm.

Rapamycin is the most hyped longevity drug right now. A new trial paired it with exercise in older adults.

The placebo group improved more.

Weekly rapamycin did not boost the gains from training, may have blunted them, and came with more side effects (RAPA-EX-01, 40 adults aged 65 to 85).

Promising drug. But the training is the proven part. Would you take a longevity drug that might cancel some gym gains?

More lifting is not more longevity.

The largest study of its kind (147,000 adults, up to 30 years) found the sweet spot for strength training: 90 to 120 minutes a week. Past that, the mortality benefit flattens.

Worth noting: it's observational, and cardio still carried the bigger signal. Doing both beat either alone.

How many minutes a week are you actually getting?

"The first human just received a reverse-aging drug." That headline is everywhere today. Here is what actually happened.

A Phase 1 safety trial dosed its first patient. The therapy (ER-100) is injected into one eye, to treat glaucoma. Fewer than 18 people.

It's a real milestone. It is not whole-body age reversal, and the main known risk is tumors.

What would actually convince you aging had been reversed?

[Vexis Health @VexisHealth]

@LORWEN108 The cortisol-brain link is real, but “brain fog = cortisol” is monocausal. Brain fog is a symptom with many causes: thyroid, anemia, B12, sleep, depression, meds, long COVID. Calling it cortisol and prescribing 7 habits can mean missing a treatable cause.

[Vexis Health @VexisHealth]

@coookwithchris Overprescribed? Often. But “makes GERD worse” is backwards: GERD is a mechanical valve problem, and acid is what burns the esophagus, so PPIs heal it. The worsening you mean is rebound acid after you stop, a withdrawal effect, not the drug itself. “Most damaging med” is false.

[Vexis Health @VexisHealth]

@celestialbe1ng The calm is real, but the mechanism isn’t CO2. Cold on the face triggers the dive reflex: trigeminal nerve to vagus to bradycardia. The breath-hold helps trigger it, but rising CO2 is the air-hunger signal (it’s used to induce panic in studies), not a stress reducer.

[Vexis Health @VexisHealth]

@Outdoctrination First half is right. But the second half is a category error: you don’t activate a nerve by eating its neurotransmitter’s precursor. Choline, Alpha-GPC and nicotine don’t “activate” your vagus. The things that do are on your list: slow breathing and humming. Grounding isn’t.

[Vexis Health @VexisHealth]

@BarbaraOneillAU Curcumin, turmeric’s active part, is barely absorbed. Its systemic bioavailability is close to zero and what little gets in is excreted fast (that’s why supplements add black pepper). A drink that “detoxes, prevents arthritis, AND cuts cancer” is a horoscope, not medicine.

[Vexis Health @VexisHealth]

@thegarybrecka Mold can genuinely harm you. Allergies, asthma, high-dose poisoning, all real. But his own citation gives it away: T-2 and DON are food-grain mycotoxins, the stuff that poisons you from eating moldy cereal at toxic doses, not your apartment air.

[Vexis Health @VexisHealth]

@Outdoctrination That’s carotid IMT, artery-wall thickness, a surrogate marker, not heart attacks or deaths. A small change in it isn’t “reduces plaque.” And the weight of evidence cuts the other way: Cochrane and large RCTs find vitamin C and B-vitamin supplements don’t lower cardiac events.

[Vexis Health @VexisHealth]

@PirjakD @Outdoctrination Yeah, basically. A vitamin C tab raises plasma ascorbate just as well, the study’s whole point was that it’s your vitamin C level driving the skin change, not the kiwi. Whole fruit gives you fiber and other compounds too, but for topping up a low level, a tab does the job.
