All ages are involved in the pursuit of cognitive well-being. Brain health is essential for everyone, including the elderly, who want to keep their minds fresh, professionals aiming for top performance, and kids pursuing academic brilliance. Yoli knows this and has conducted significant studies demonstrating omega-3 fatty acids’ critical role in maintaining cognitive function throughout life.

Your Brain on Omega-3s: The Critical Role of EPA and DHA

The human brain is nearly 60% fat; among these, omega-3 fatty acids—particularly EPA and DHA—play a vital role in brain structure and function. Unlike other organs, the brain cannot efficiently produce these essential fatty acids, meaning they must be obtained from the diet—primarily from fatty fish or omega-3 supplementation, such as those offered by Yoli.  

DHA is particularly crucial as it makes up about 30% of the brain’s gray matter, which is responsible for cognition and memory. Studies have shown that DHA supplementation may slow cognitive decline and even reduce neuroinflammation.  

EPA, while present in lower levels than DHA, is equally essential for mental clarity and anti-inflammatory support. Studies have found that those with higher Omega-3 Index scores had larger brain volumes and better cognitive performance.  

• DHA is essential for brain structure, memory retention, and neuron protection.
• EPA plays a key role in reducing neuroinflammation and supporting mood stability.  
• Research indicates that a balanced intake of omega-3s may reduce the risk of neurodegenerative diseases.

EPA’s Role in Brain Function and Mood

While DHA dominates structural roles, EPA plays a crucial role in mood regulation and anti-inflammatory pathways. Studies have shown that EPA levels in the brain are naturally lower than DHA, but its presence is essential for reducing neuroinflammation and supporting mental clarity.

In a study on individuals with mild cognitive impairment, EPA+DHA supplementation improved memory scores and increased hippocampal volume, a region critical for learning and memory.

Omega-3s and Cognitive Aging

Cognitive health is a significant concern as we age. Research has highlighted omega-3s as a key factor in healthy brain aging. Studies have shown associations between higher plasma DHA levels and healthy cognitive function and that individuals with higher Omega-3 Index scores tended to have larger brain volumes and better mental performance. 

Controlled studies have demonstrated that EPA and DHA supplementation may affect brain health. 

Why the Omega-3 Index Matters for Brain Health

The Omega-3 Index, a measure of EPA and DHA levels in red blood cells, has been established as a significant biomarker for cognitive function. A 10-year study found that women with higher Omega-3 Index scores experienced a slower rate of cognitive decline and a significantly lower risk of developing dementia.

Low Omega-3 Index levels may improve with proper dietary intake and supplementation, such as those provided by Yoli. Many Yoli customers have reported increases in their Omega-3 Index levels. For example, some have seen their levels rise from below 4% to over 10%, while others have moved from the mid-8% range to nearly 12%.

The Challenge: Not All Omegas Are Created Equal

While omega-3s are essential, not all sources are equally effective. Research confirms that only EPA and DHA from marine sources—such as fish or high-quality supplements—can significantly raise Omega-3 Index scores. 

Finding the Right Omega Solution for Cognitive Health

With growing scientific evidence on the role of omega-3s in brain aging, ensuring a full-spectrum omega profile is more important than ever. Experts recommend looking for supplements with high concentrations of EPA and DHA, proven bioavailability, additional omega forms (3, 7, 9, 11), and sustainable, pure sources.  

When choosing an omega-3 supplement, looking for high concentrations of EPA and DHA, proven bioavailability and sustainably sourced ingredients is essential. Yoli’s formulations are developed with these factors in mind, offering a convenient way to support cognitive health.

As more research continues to validate the decisive role of omega-3s in protecting brain function, making omega optimization a daily priority may be one of the simplest and most effective ways to support cognitive longevity and memory health. 

Maintaining a balanced intake of omega-3s and other healthy lifestyle choices can be part of a proactive approach to overall wellness. Consulting a healthcare professional can help determine individual dietary needs and appropriate strategies for omega-3 intake. Prioritizing brain health is a long-term commitment, and Yoli aims to support individuals on their wellness journey.

The research clearly demonstrates the link between omega-3s and cognitive well-being. Dr. William Harris, a leading researcher on omega-3s and a member of Yoli’s Life Sciences Council, shares his expertise: “DHA is essential for brain function at all stages of life. Ensuring optimal levels may help slow cognitive decline and reduce neuroinflammation.” Dr. Harris adds, “The Omega-3 Index is emerging as a strong predictor of cognitive health. Low levels of EPA and DHA are consistently linked to cognitive challenges.”
