Red wine 150 mL/day,
does it really help with Lower all-cause mortality and longer life?
research showsThe grade is C. A cohort of 333,247 U.S. adults found 21%-22% lower all-cause mortality hazards among light and moderate drinkers, and a beverage-specific UK Biobank analysis reported a favorable association for 1-1.5 glasses of red wine per day. Neither was randomized, so the magnitude of association is not the magnitude of a causal longevity effect.
ads claimRed wine does contain resveratrol. The 0.362-1.979 mg/L range is a measured range for French Pinot Noir, not a universal range for all red wines; it gives about 0.054-0.297 mg in 150 mL. Human supplement trials often use 500-1,000 mg/day, roughly 1,700-18,500 times as much. This composition fact cannot be converted into longer life from one glass.
Useful facts when choosing a product
- At 14.2% alcohol by volume, 150 mL contains about 16.8-16.9 g ethanol using a density of 0.789 g/mL.
- The 0.362-1.979 mg/L measured in French Pinot Noir equals about 0.054-0.297 mg per 150 mL.
- Supplement verdict 090 is C with 48 points, verdict 1076 is D with 28 points, and verdict 1108 is D with 28 points; high-dose supplements are not wine consumed with alcohol.

What the research actually shows
Xi linked 13 NHIS waves to mortality in 333,247 adults, with median follow-up of 8.2 years and 34,754 deaths. Schutte analyzed beverage type in 502,635 UK Biobank participants over about seven years. The red-wine HR of 0.81 (0.73-0.89) for 1-1.5 glasses/day comes from the U.S. National Academies review table and was not independently rechecked against the original article table. Both are self-reported observational datasets subject to exposure change, reference contamination, and model dependence.
Why this is classified as C (56)
A large beverage-specific mortality association exists, but it is not causal and is vulnerable to reference contamination, one-time self-report, and model dependence, giving C with 56 points.
Counterpoint. Lower mortality hazards were observed in both total-alcohol and beverage-specific red-wine analyses. Neither is a trial showing that starting 150 mL of red wine extends life.
Rejudgment record. Cross-check applied — Favorable total-alcohol and beverage-specific red-wine associations were retained while accounting for reference contamination, one-time self-report, model dependence, and noncausal interpretation
| Endpoint | H | Hard endpoint - actual events such as death |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | E+ | Meets the clinically important threshold |
Stored derived and displayed grades match; this is not a current recalculation or validity check (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Observed association of low-to-moderate total drinking and red wine with lower mortality | C | It appeared in large total-alcohol and beverage-specific cohorts. |
| Starting 150 mL of red wine extends life | ? | No long-term trial randomized red wine itself and measured all-cause mortality. |
