People with higher blood levels of lycopene have a 37% lower risk of death.
See the scientific wording
Higher serum lycopene concentrations are associated with a 37% reduction in all-cause mortality risk.
Backed by science
One low-scoring study supports this claim, so treat this as an early signal rather than settled science.

Systematic Review With Meta-AnalysisMeta-analysis2019
This study found that people with the highest levels of lycopene in their blood had a 37% lower risk of dying, which matches the claim exactly.

That doesn't mean it's settled — it just means no study has tested the opposite.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
Lycopene is a powerful antioxidant found in tomatoes and other red fruits. It helps protect your cells from damage caused by harmful molecules called free radicals. By neutralizing these free radicals, lycopene reduces inflammation and keeps blood vessels healthy. This lowers the chance of developing deadly diseases like heart disease and cancer, which is why higher lycopene levels are linked to living longer.

People with higher blood levels of lycopene have a 37% lower risk of death.
Mechanism
1 studyLycopene works like a shield for your cells, stopping harmful molecules from causing damage and inflammation. This keeps your heart and other organs healthy, so you are less likely to die from common diseases like heart attacks or cancer. Because we don't have direct proof from these studies, this explanation is based on what we know about how antioxidants work in general.

Lycopene accumulates in blood and tissues and scavenges reactive oxygen species, reducing oxidative stress.
Reduced oxidative stress decreases the activation of pro-inflammatory signaling pathways, such as NF-κB, leading to lower levels of inflammatory cytokines.
Lower oxidative stress and inflammation protect endothelial function, reduce atherosclerosis progression, and inhibit carcinogenesis.
These protective effects reduce the incidence and progression of cardiovascular disease and cancer, thereby lowering all-cause mortality.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review and Meta-Analysis of Prospective Cohort Studies on Serum Lycopene and All-Cause Mortality
Comprehensive search of databases for prospective cohort studies measuring serum lycopene and reporting all-cause mortality, with meta-analysis of adjusted hazard ratios.
Randomized Controlled Trial of Lycopene Supplementation on Mortality in Middle-Aged Adults
Double-blind, placebo-controlled RCT with at least 10-year follow-up, randomizing participants to lycopene supplement (e.g., 15 mg/day) or placebo, measuring all-cause mortality.
Prospective Cohort Study on Serum Lycopene and Mortality Risk in a General Population
Large prospective cohort (n > 10,000) with baseline serum lycopene measurement, follow-up >10 years, adjusting for confounders like age, smoking, diet.
Case-Control Study of Serum Lycopene Levels in Deceased vs Living Individuals
Nested case-control within a cohort, selecting cases who died and matched controls, measuring stored serum samples for lycopene.
