Hype vs evidence — the anti-hype firewall

A no-bullshit filter for longevity trends: the claim, what the evidence actually says, and whether it deserves your attention.

• Perfect morning routine: “A perfect morning routine optimises your hormones, energy and longevity.” — Stable routines can make useful behaviours easier to repeat. No universal sequence of light, cold, supplements and training has been shown to optimise health or extend life. Choose a simple routine that protects sleep, daylight, movement and a reliable daily rhythm. Keep only the parts you can sustain.
• Creatine: “Builds strength and maybe cognition.” — One of the most-studied, safe supplements: solid for strength/muscle, promising for cognition. Often yes, especially if strength, muscle, vegetarian diet or cognition are priorities.
• Omega-3 (EPA/DHA): “Heart and brain benefits.” — Clear triglyceride effects and plausible anti-inflammatory benefit; strongest case if fish intake is low or triglycerides are high. Worth considering if you rarely eat oily fish; less magic if your diet is already rich in EPA/DHA.
• Sauna: “Frequent sauna extends life.” — Strong observational link to lower cardiovascular mortality; RCT proof for longevity is still missing. Potentially worth it if you enjoy it and tolerate heat; not a replacement for training.
• Rapamycin: “The longevity drug.” — Extends lifespan in animals; human longevity unproven, prescription-only, immune/metabolic monitoring required. Frontier only. Not a casual wellness intervention; clinician supervision is non-negotiable.
• Time-restricted eating: “Fasting windows melt fat and slow aging.” — Helps some people reduce calories and improve routines; benefits beyond calorie reduction are modest. Worth it if it improves adherence; not worth it if it harms protein intake, sleep or training.
• NMN / NR (NAD+ boosters): “Reverses aging by raising NAD+.” — Can raise NAD+ related markers, but no proven human anti-aging or healthspan outcome yet. Usually not first-line. Measure basics before spending here.
• Personalised nutrition tests (microbiome / glucose scores): “A gut-microbiome and blood-sugar test tells you exactly what to eat.” — The science is real — after-meal glucose and fat responses genuinely vary between people — but whether a paid "score" beats the free basics (more fibre, more plant variety, fewer ultra-processed foods) is not yet established. The free universal advice captures most of the benefit; the paid test is optional, not proven to change outcomes.
• Cold plunge: “Boosts metabolism, recovery and longevity.” — Mood/alertness and soreness effects are plausible; may blunt muscle gains right after lifting; longevity unproven. Worth it if you love it; avoid after hypertrophy training if muscle gain is the goal.
• Berberine: “Nature's Ozempic.” — Modestly lowers glucose and lipids in some studies; nowhere near GLP-1 drugs; quality and interactions vary. Maybe for glucose/lipid context, but check meds and do not compare it to GLP-1 therapy.
• Collagen: “Younger skin and joints.” — Some signal for skin elasticity and joint comfort; effects are modest. Reasonable if skin/joint comfort matters; not a longevity pillar.
• Red-light therapy: “Skin, recovery, hair, mitochondria.” — Reasonable evidence for skin and some pain/hair uses; broad mitochondrial claims outpace data. Maybe for specific skin/pain goals; skip broad anti-aging claims.
• Metformin (healthy people): “Everyone should take it for longevity.” — Great diabetes drug; longevity benefit in non-diabetics unproven and may blunt exercise adaptations. Not a default for healthy people. Discuss only with medical context.
• Resveratrol: “Red-wine molecule activates longevity genes.” — Human trials have largely disappointed; classic hype outrunning evidence. Usually no. Spend attention on exercise, sleep and nutrition.
• High-dose antioxidants: “Mop up free radicals, slow aging.” — Megadoses can blunt training adaptations and some raise risk; food patterns are safer. Usually avoid megadoses unless treating a documented deficiency.
• Apple cider vinegar: “Fat loss and blood-sugar fix.” — Tiny glucose effect at best; not a weight-loss tool; can harm teeth/throat. Not meaningful for longevity. Fine as food, not as protocol.
• Greens powders: “Replace your vegetables.” — Expensive insurance at best; no substitute for real vegetables, legumes and fibre. Mostly no. Buy real food first.
• Methylene blue: “Brain and mitochondrial enhancer.” — Trendy online; human longevity/cognition evidence is thin and dosing/interactions are risky. No for self-experimentation without medical supervision.
• Grounding / earthing: “Touching the earth cures inflammation.” — No credible mechanism or solid evidence. Walk outside because nature and movement help; not because electrons cure aging.
• BPC-157 & research peptides: “Heals everything.” — Mostly animal/anecdote; unregulated, unproven and legally grey in humans. No as a consumer longevity intervention.
• Coffee (3–5 cups): “Coffee is bad for you.” — The opposite leans true: moderate coffee is associated with lower all-cause and cardiovascular mortality. A paper filter avoids the LDL-raising oils. Enjoy it if you tolerate it; mind caffeine timing for sleep.
• Green tea (the drink): “Green tea is a longevity elixir.” — Regular tea links to modestly lower mortality (observational); caffeine + L-theanine aids calm focus. Safe and reasonable, not magic. Yes as a pleasant, low-risk habit.
• EGCG extracts (high-dose): “Concentrated green-tea pills burn fat and extend life.” — High-dose catechin supplements (≥800 mg EGCG/day) are linked to liver injury (EFSA) with little outcome benefit — a risk drinking tea does not carry. No. Drink the tea; skip the high-dose extract.
• Alkaline water: “High-pH water detoxifies and fights disease.” — The body tightly controls blood pH; alkaline water does not change it. No credible outcome evidence. No. Clean plain water does the same job for free.
• Hydrogen water: “Hydrogen-infused water slows aging.” — A few small, short studies on oxidative-stress markers — preliminary, not established health outcomes. Not yet — interesting but unproven and pricey.
• Structured / hexagonal water: “"Living" structured water hydrates better.” — No physical basis — water has no special stable structure when you drink it. Pseudoscience. No.
• 8 glasses of water a day: “Everyone must drink exactly 8 glasses daily.” — No strong basis for a fixed number; total water (~2.0–2.5 L incl. food) varies by person, heat and activity. Thirst and pale urine guide most people well. Drink to thirst; a rigid quota is unnecessary.
