What Is Lycopene? Antioxidant Activity, Skin, Heart Health and What Research Shows

Lycopene is the red carotenoid most closely associated with tomatoes, but its scientific story goes beyond food color.

It is widely studied for its chemical antioxidant activity, particularly its ability to interact with singlet oxygen and other reactive species. Human research has also examined lycopene and tomato-based foods in relation to skin responses to ultraviolet exposure, cardiovascular risk markers, oxidative-stress biomarkers, and several other areas of health.

That does not mean lycopene acts as a literal shield around your cells or that taking a lycopene supplement prevents aging, protects DNA, or guarantees cardiovascular benefits.

“Lycopene has well-established antioxidant chemistry, but antioxidant activity in a laboratory is not the same as proving that a supplement prevents cellular aging or disease in humans.”

What Is Lycopene?

Lycopene belongs to the carotenoid family of naturally occurring plant pigments.

Carotenoids help plants interact with light and participate in protection against photooxidative stress.

Tomatoes and tomato-based foods are among the major dietary sources of lycopene, although it is also found in foods such as:

• Watermelon
• Pink grapefruit
• Guava
• Papaya
• Rose hips

Lycopene is structurally different from carotenoids such as beta-carotene.

Beta-carotene can function as a provitamin A compound, meaning the body can convert it into vitamin A.

Lycopene does not have provitamin A activity.

Its scientific interest instead comes largely from its chemical structure, antioxidant-related behavior, distribution in human tissues, and associations with several areas of nutritional research.

Why Is Lycopene Called an Antioxidant?

Lycopene contains a long chain of conjugated double bonds.

This structure allows it to interact with certain reactive molecules, including singlet oxygen, a highly reactive form of oxygen involved in photooxidative and other oxidative processes.

Laboratory comparisons have found lycopene to be an efficient singlet-oxygen quencher.

This is scientifically meaningful, but the phrase “powerful antioxidant” can easily become oversimplified in supplement marketing.

These are three different levels of evidence.

A compound performing strongly in a chemical antioxidant assay does not automatically mean that a person taking it is protected from cardiovascular disease, DNA damage, skin aging, or systemic aging.

Does Lycopene Prevent Oxidative Damage to Cells?

Lycopene is frequently described as protecting cellular membranes from lipid peroxidation.

There is a biological basis for studying this idea because lycopene is lipophilic and can associate with lipid-containing environments, while oxidative reactions involving lipids are an established part of redox biology.

However, describing oral lycopene as a physical “cellular shield” is too literal.

Human oxidative biology involves a large network of:

• Reactive oxygen and nitrogen species
• Endogenous antioxidant enzymes
• Glutathione systems
• Dietary compounds
• Inflammatory signaling
• Mitochondrial metabolism
• Immune activity

Reactive molecules are not simply harmful waste products. They also participate in normal cellular signaling.

For that reason, “neutralizing free radicals” should not be presented as though more antioxidant activity always produces better health.

What Does Human Research Show About Lycopene and Skin?

Skin photobiology is one of the more interesting areas of human lycopene research.

Several intervention studies have examined tomato products or lycopene-containing interventions in relation to skin responses after ultraviolet exposure.

For example, a randomized study in healthy women tested tomato paste providing approximately 16 mg of lycopene per day together with olive oil for 12 weeks.

Researchers reported changes in several measurements related to UV-induced skin responses compared with the control intervention.

A later systematic review and meta-analysis combining intervention studies reported that tomato- and lycopene-based interventions were associated with changes in measures including:

• UV-induced erythema-related measurements
• Skin pigmentation
• Minimum erythema dose in pooled analyses
• Selected molecular markers related to UV exposure
• Skin thickness and density in selected studies

This supports continued interest in lycopene-rich foods and lycopene within nutritional photoprotection research.

It is also important to distinguish studies using tomato paste or lycopene-rich foods from studies using isolated lycopene supplements.

Tomato foods contain additional carotenoids, polyphenols, vitamins, and other compounds, so their findings cannot always be attributed entirely to lycopene.

What Does Research Show About Lycopene and Cardiovascular Health?

Lycopene has also been widely studied in relation to cardiovascular risk factors.

Human intervention research has examined outcomes such as:

• Blood pressure
• LDL cholesterol
• HDL cholesterol
• Triglycerides
• Endothelial function
• Inflammatory biomarkers
• Oxidative-stress markers

The evidence has not always been consistent.

Earlier systematic reviews found substantial variation between trials, including differences in:

• Lycopene dose
• Tomato foods vs. isolated supplements
• Use of oils or other foods
• Baseline cardiovascular risk
• Study duration
• Outcome definitions

A 2026 umbrella review of systematic reviews and meta-analyses reported the clearest evidence for changes in blood pressure, while findings for lipid profiles remained less consistent.

This does not justify describing lycopene as a treatment for hypertension or cardiovascular disease.

It is more accurate to say that tomato-derived lycopene has been studied in relation to cardiovascular risk markers, with some outcomes showing stronger evidence than others.

Does Lycopene Protect DNA or Slow Aging?

This has not been established as a general clinical effect of lycopene supplementation.

Oxidative DNA damage is studied in redox biology, and some human interventions have measured DNA-related biomarkers.

But a change in an oxidative-damage marker does not establish that a supplement:

• Repairs DNA
• Prevents mutations
• Prevents cancer
• Slows biological aging
• Extends lifespan

Likewise, describing lycopene as maintaining a “youthful cellular environment” turns a broad biological hypothesis into an outcome that has not been demonstrated.

Healthy aging is influenced by genetics, metabolic health, physical activity, sleep, diet, smoking exposure, medical conditions, medications, and many other factors.

No single carotenoid can represent the entire biology of aging.

Why Does Lycopene Bioavailability Matter?

Lycopene is fat-soluble, and the amount that reaches the circulation depends on more than the number of milligrams consumed.

Important factors include:

• The food or supplement matrix
• Processing
• Isomer composition
• Dietary fat
• Digestive conditions
• Individual differences in absorption and metabolism

Fresh tomatoes contain lycopene predominantly in the all-trans form.

Processing can disrupt the plant matrix and change the proportion of trans and cis isomers.

Several human and mechanistic studies suggest that certain cis-lycopene forms may be more bioavailable than all-trans lycopene under some conditions.

Eating lycopene-containing foods together with dietary fat can also improve carotenoid absorption.

Is Lycopene From Food Better Than Lycopene From Supplements?

They should not be treated as identical interventions.

A tomato contains lycopene within a complex food matrix alongside:

• Other carotenoids
• Vitamin C
• Potassium
• Fiber
• Polyphenols and other phytochemicals

An isolated supplement may provide a concentrated lycopene ingredient with a different matrix and different bioavailability characteristics.

This means a study using tomato paste cannot automatically prove the same effect for every lycopene capsule.

Likewise, an isolated lycopene trial does not establish that every tomato product produces the same result.

How Much Lycopene Is in RevitaPlus NAD+?

The current RevitaPlus NAD+ Supplement Facts information identifies a supplement component containing:

• Lycopene 5% ingredient — 80 mg
• Beta-carotene 30% ingredient — 15 mg

This distinction matters when comparing the formula with human studies.

A trial using a defined amount of isolated lycopene or a tomato product providing a measured amount of lycopene is not automatically equivalent to an 80 mg ingredient standardized or identified at 5% within a multi-ingredient supplement.

The RevitaPlus NAD+ pack also contains a 600 mg NAD Natural Blend, a trans-resveratrol-containing formula, and a PQQ-containing formula.

Is Lycopene Safe?

Lycopene from foods has a long history of dietary exposure.

Supplement tolerance can depend on dose, formulation, other ingredients, health status, and duration of use.

High dietary intake can sometimes produce a harmless orange-red discoloration of the skin known as lycopenodermia, which generally resolves when intake is reduced.

People who are pregnant or breastfeeding, take prescription medication, are receiving treatment for a medical condition, or use several supplements should review concentrated supplemental ingredients with a qualified healthcare professional.

Safety of the complete RevitaPlus NAD+ formula should be assessed according to the entire ingredient panel rather than lycopene alone.

The Key Takeaway

Lycopene is a carotenoid with well-established antioxidant chemistry and a substantial body of nutritional research.

Human studies provide particularly interesting evidence in areas such as skin responses to UV exposure and selected cardiovascular risk markers.

But the evidence does not justify describing lycopene as:

• A physical shield around cells
• A proven DNA-protection supplement
• A treatment for cardiovascular disease
• A supplement that prevents skin aging
• A compound that prevents systemic aging
• A clinically proven longevity ingredient

When evaluating a lycopene product, look at the actual ingredient form, concentration, serving amount, food or supplement matrix, population studied, and outcome measured.

Antioxidant chemistry is an important starting point.

It is not the same thing as a guaranteed clinical result.
