These are the ones with the strongest research behind them — each graded on real human and mechanistic evidence and linked to its PubMed citations.* ## What “evidence-based” actually means here Every product on Magellan is graded on the *strength of the research* behind its active compound — not on star ratings or marketing. Grades run from Strong and Moderate down to Emerging and Preliminary, and each links to the primary peer-reviewed studies so you can read the source yourself. Grades are independent of any affiliate commission.

Small human RCTs show anti-inflammatory effects (for example 100 mg/day for 7 weeks in cancer patients), but no published trial has shown senescent-cell clearance or aging benefits in healthy people. Anti-aging use remains speculative pending larger trials. ### Quercetin Capsules - **Evidence grade:** Moderate evidence - **Dose used in studies:** ≥500 mg/day (blood-pressure effects appear mainly at 500 mg/day and above) - **What the grade does not say:** Meta-analyses show a small (~2–3 mmHg) blood-pressure reduction, mostly in people with hypertension; lipids and glucose show no meaningful effect, and oral bioavailability is poor. The headline 'senolytic' claims come from the dasatinib+quercetin drug combination in early trials — the biggest 2024 trial was negative overall — not from quercetin capsules alone. ### Double Wood NMN Capsules - **Evidence grade:** Moderate evidence - **Dose used in studies:** Human RCTs used 250–1,200 mg/day orally; well-tolerated up to ~900 mg/day, with one dose-finding trial reporting benefits peaking near 600 mg/day. Most trials run 6–12 weeks. - **Dose from food:** Only trace amounts in food: edamame, broccoli and avocado supply roughly 0.25–1.9 mg per 100 g. You'd need dozens of pounds to match a single 250–600 mg dose, so diet can't reach studied levels. - **What the grade does not say:** Oral NMN reliably raises blood NAD⁺ and has been well tolerated in trials up to about 900–1,250 mg/day. Functional benefits so far are modest and population-specific (muscle insulin sensitivity in prediabetic women, aerobic capacity, walking speed, sleep quality), several meta-analyses are null for glucose, lipids and muscle mass, and no trial shows effects on aging, disease prevention, or lifespan. ### Spermidine (Wheat-Germ Extract) - **Evidence grade:** Moderate evidence - **Dose used in studies:** Cognition trials in older adults used modest, food-level doses of wheat-germ extract: 0.9 mg/day for 12 months (SmartAge) and 1.2 mg/day for 3 months. Higher doses are less studied. - **Dose from food:** Readily obtained from food: wheat germ holds ~24–35 mg per 100 g (about 2–2.5 mg per tablespoon); natto, aged cheese, mushrooms and soy are rich too. A normal diet supplies ~10–15 mg/day, exceeding the doses tested. - **What the grade does not say:** The preclinical case is unusually strong and several large prospective cohorts link higher dietary spermidine intake to lower mortality — but that is observational and confounded by diet quality. The most rigorous human trial to date (12-month SmartAge) found no cognitive or biomarker benefit at the 0.9 mg/day dose used in supplements, and oral bioavailability is unsettled. ## Frequently asked questions ### What are the best evidence-based longevity supplements? The compounds with the most human and mechanistic support include senolytics (fisetin, quercetin), NAD⁺ precursors (NMN), spermidine, urolithin A, trans-resveratrol, omega-3, vitamin K2 and sulforaphane. Each is graded and cited on its product page. ### Do longevity supplements actually work? Evidence varies a lot by compound — some have human randomized trials, others only animal or mechanistic data. That is exactly why every Magellan product carries an evidence grade and links to its studies, so you can judge for yourself rather than trust a label. ### What does the evidence grade mean? It reflects how strong the published research is for the active compound — from Strong (human RCTs) to Preliminary — and is set independently of affiliate commissions. ### Are longevity supplements FDA approved? Dietary supplements are not FDA-approved to treat disease. They are intended to support general wellness. Always talk to your physician before starting one. ## The research behind these picks Primary peer-reviewed sources for the products above.
