Taking lycopene supplements alone has only a small effect on lowering the risk of heart attacks and other cardiovascular events. The evidence indicates that the benefit is not substantial.
See the scientific wording
Isolated lycopene supplementation provides limited benefit in reducing cardiovascular disease endpoints, including heart attacks.

What the research says
2 studies reviewedSupporting (2)
Randomized Controlled TrialHuman2018
The study found that regular lycopene pills did not improve heart health markers, but a special version with better absorption did. This means taking plain lycopene supplements probably won't do much to prevent heart attacks.
Systematic Review With Meta-AnalysisMeta-analysis2017
The study looked at lycopene supplements and found they only slightly lowered blood pressure, but didn't check if people actually had fewer heart attacks, so the benefit for preventing heart attacks seems small.

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 substance that fights harmful molecules in the body called free radicals. It gets into the blood and tissues after you take it, but the amount that reaches the arteries is small. It can slightly reduce damage to blood vessel walls, but its effect on inflammation and plaque buildup is too weak to stop heart attacks by itself.

Mechanism
2 studiesLycopene is thought to work by protecting blood vessels from damage, but the body only absorbs a tiny amount from supplements. This small amount is not enough to stop the buildup of plaque in arteries or prevent heart attacks.
Lycopene is a substance that fights harmful molecules in the body called free radicals. It gets into the blood and tissues after you take it, but the amount that reaches the arteries is small. It can slightly reduce damage to blood vessel walls, but its effect on inflammation and plaque buildup is too weak to stop heart attacks by itself.
Ingested lycopene is absorbed in the intestine and transported via lipoproteins to tissues, including the arterial wall, but bioavailability is limited and varies greatly.
In the arterial wall, lycopene scavenges reactive oxygen species, reducing oxidative stress and inhibiting oxidation of low-density lipoprotein (LDL).
Reduced LDL oxidation decreases foam cell formation and early atherosclerotic plaque development, but the magnitude of this effect from isolated lycopene is insufficient to significantly alter plaque progression.
The modest reduction in oxidative stress does not substantially lower systemic inflammation or improve endothelial function enough to prevent thrombotic events like heart attacks.
