Olive oil is a polyphenol-rich functional fat that delivers benefits far beyond its caloric content. It supports cardiovascular, metabolic, and cognitive function while reducing inflammation and oxidative stress, both core drivers of biological aging. From influencing gene expression to improving insulin sensitivity, olive oil is a proven ally in the science of healthy aging.

What Is Olive Oil?

Olive oil is a nutrient-dense oil extracted from the fruit of the olive tree (Olea europaea), and is a foundational component of the Mediterranean diet. It is valued not just for its healthy fats, but for its high concentration of bioactive polyphenols—especially hydroxytyrosol and oleuropein—which play a key role in metabolic regulation, antioxidant defense, and inflammation control.

Sources of Olive Oil:

• Extra virgin olive oil (EVOO)
• Cold-pressed and unrefined varieties
• Highest in polyphenols when minimally processed

These compounds have been shown in human studies to reduce inflammation, improve metabolic markers, and modulate gene expression. While most dietary fats supply only calories, olive oil delivers functional molecules that interact with aging pathways.

However, the average Western diet is low in high-quality, polyphenol-rich olive oil. In contrast, clinical studies showing metabolic and anti-inflammatory benefits typically use 10–30 grams per day of extra virgin olive oil. With 1.5 grams per NOVOS Bar, this formulation delivers a consistent microdose of these compounds and provides meaningful, daily support for healthy aging without the need for large dietary shifts.

Potential Health Benefits of Olive Oil

Olive oil demonstrates a wide range of clinical benefits in human trials:

• Inflammation control: Olive oil polyphenol supplementation reduces chronic inflammation, lowering CRP, IL-6, and TNF-α in adults with metabolic risk, supporting immune balance and vascular function.
• Metabolic regulation: Daily olive oil intake improves fasting glucose, HbA1c, and insulin sensitivity in individuals with prediabetes and metabolic syndrome, enhancing nutrient sensing and metabolic stability.
• Cardiovascular performance: Olive oil improves lipid profiles (↓ LDL, ↑ HDL), supports blood pressure regulation, and enhances endothelial function, contributing to cardiovascular resilience.
• Antioxidant activity: Polyphenols such as hydroxytyrosol and oleuropein enhance redox balance and reduce oxidative markers, protecting cells from damage and supporting mitochondrial health.
• Epigenetic modulation: Olive oil compounds influence gene expression at the epigenetic level, regulating aging-related pathways and contributing to cellular homeostasis.
• Cognitive function: In aging adults, olive oil polyphenols have been linked to improved memory and executive function, likely mediated by anti-inflammatory, vascular, and mitochondrial mechanisms.

The Role of Olive Oil in Aging and Longevity

• Olive oil polyphenols improve key aging biomarkers, including inflammation, lipid profiles, and blood glucose regulation.
• Supplementation with hydroxytyrosol and oleuropein has been shown to reduce CRP, IL-6, and TNF-α in human clinical trials.
• Olive oil improves HDL and lowers LDL cholesterol, supporting long-term cardiovascular health.
• Higher intake is linked to improved insulin sensitivity, waist circumference, and pancreatic function—hallmarks of metabolic stability.
• Olive oil polyphenols support epigenetic regulation, influencing gene expression tied to aging.
• A 2022 meta-analysis found that higher olive oil consumption is associated with an 11% reduction in all-cause mortality.
• Olive oil supports multiple aging pathways, including oxidative stress, nutrient sensing, inflammation, and intercellular signaling.

Olive Oil and Healthy Aging

When it comes to healthy aging, olive oil is more than just a healthy fat, it’s a source of powerful compounds like hydroxytyrosol and oleuropein, which have been tested in human clinical trials. A 2024 systematic review of randomized controlled trials looked at how these two molecules affect aging-related processes in real people and found consistent improvements in markers that matter for longevity,  including inflammation, blood lipids and glucose metabolism [R] . These effects were seen in adults with mild inflammation or metabolic risk but also in generally healthy individuals.

This clinical evidence is captured in a visual summary from the same study showing how OLE and HT improve cardiometabolic and inflammatory markers based on data from 11 trials in humans.

Figure 1: OLE and HT improve inflammation, blood sugar, cholesterol, and more,  based on human trials (Frumuzachi et al., 2024)

In addition to this clinical data individual studies at the population level show long-term benefits as well In a 2022 meta-analysis combining results from over 1 million people those who consumed more olive oil had a significantly lower risk of death from any cause [R].

This relationship is illustrated in the figure below where each line represents a different study. Almost all show the same result, olive oil intake is associated with a lower risk of death from any cause over time, “with an overall reduction of 11 percent in all-cause mortality!”

Figure 2: Higher olive oil intake is consistently linked to lower all-cause mortality across multiple population studies.” The combined effect shows an 11% risk reduction (Martínez-González et al 2022)”

These findings reinforce olive oil’s role as a clinically supported, food-based intervention that targets multiple aging mechanisms and is consistently associated with improved healthspan and reduced mortality risk.

Is Olive Oil Good for Anti-Aging?

These mechanisms are all supported by randomized controlled trials (RCTs) in humans. These are trials with a placebo group (which controls for placebo effects) and in which participants are randomly allocated to the experimental or control groups (which removes allocation bias). RCTs are considered the gold standard in clinical human research.

• Inflammation and Oxidative Stress :Supplementation with olive oil polyphenols has been shown to reduce levels of chronic inflammation, including CRP, IL-6, and TNF-α, especially in adults with metabolic risk [R]. While antioxidant effects have been more variable, some trials also show improved redox balance and reduced oxidative markers, particularly in populations with elevated baseline stress [R].
• Blood Lipids and Cardiovascular Health : Daily intake of olive oil polyphenols improves lipid profiles by reducing LDL, increasing HDL, and sometimes lowering total cholesterol [R]. These changes are considered highly relevant for long-term cardiovascular resilience. In one large meta-analysis, higher olive oil consumption was associated with a significant reduction in all-cause mortality, largely driven by cardiovascular protection [R].
• Metabolic Function and Blood Sugar: Olive oil compounds help improve fasting blood glucose, HbA1c, and insulin sensitivity, particularly in individuals with prediabetes or metabolic syndrome. Some trials also report improvements in pancreatic β-cell function and reductions in waist circumference and fat mass, markers tied to healthier nutrient sensing and systemic metabolism [R].
• Blood Pressure and Vascular Function: Several trials report reductions in systolic and diastolic blood pressure with olive oil supplementation. While effects vary by population, these changes have been observed even in non-hypertensive adults and are thought to reflect improved endothelial function and arterial tone [R].
• Cognitive Health and Aging: Emerging data suggest that hydroxytyrosol and oleuropein may have positive effects on cognitive performance and executive function, particularly in aging adults. These effects are likely mediated by a combination of anti-inflammatory, vascular, and mitochondrial mechanisms, all of which are essential for brain health over time  [R].

Olive Oil Dosage and Safety: How Much Is Safe for Longevity?

Each NOVOS Bar delivers 1.5 grams of extra virgin olive oil, providing a daily dose of polyphenols shown to support inflammation reduction, lipid regulation, and oxidative stress balance.

Two bars per day (3 grams total) help move closer to the lower end of the clinically studied range, offering a practical way to incorporate the benefits of olive oil into a daily longevity routine.

Olive oil polyphenols are well-tolerated and approved for use in food supplements by regulatory authorities in both Europe and the US, making this formulation a safe and effective option for long-term use.

→ 1 bar/day offers foundational polyphenol support.

→ 2 bars/day move closer to the range studied in clinical trials.
