What Are Essential Fatty Acids? Why Your Body Needs Healthy Fats Daily

Supporting your health at a cellular level

When it comes to supporting your health, it’s easy to focus on individual concerns such as energy, digestion, skin, or focus.

But long-term wellbeing starts much deeper.

It starts at a cellular level.

One of the most important, yet often misunderstood, parts of cellular health is essential fatty acids - the healthy fats your body needs but cannot make on its own.

What are essential fatty acids?

Essential fatty acids are types of fat that your body cannot produce by itself, which means they must come from your diet. They are called “essential” because they play an important role in normal body function, including cell structure, brain health, and overall wellbeing.

According to the NHS guide to different fats and nutrition , fat is an important part of a healthy, balanced diet and helps the body absorb certain vitamins.

The two main essential fatty acids are:

• Omega 3 fatty acids
• Omega 6 fatty acids

Omega 9 is also an important fatty acid, although it is not classed as “essential” because the body can produce some on its own.

Essential fatty acids help support:

• Cell structure
• Brain function
• Nutrient absorption
• Skin health
• General wellbeing

Every cell in your body relies on healthy fats to function properly.

Why healthy fats matter at a cellular level

Each of your cells is surrounded by a membrane made up partly of fatty acids. These membranes help control what enters and leaves the cell, support communication between cells, and help maintain overall cell integrity.

When your diet includes a balanced intake of healthy fats, especially omega 3 and omega 6, your body has the nutritional building blocks it needs to support everyday health.

This is why essential fatty acids are often linked to foundational wellness rather than just one specific area of the body.

Omega 3, 6 and 9: what’s the difference?

Omega fatty acids are often grouped together, but they each play slightly different roles.

Omega 3

Omega 3 fatty acids are widely known for supporting brain, heart, and overall wellbeing. Common food sources include oily fish, flaxseed, chia seeds, walnuts, and certain plant-based oils.

The National Institutes of Health omega-3 fatty acids factsheet provides further information on omega 3 fatty acids, including ALA, EPA and DHA.

Omega 6

Omega 6 fatty acids are also essential and must come from the diet. They are found in many nuts, seeds, and vegetable oils. The key is not to avoid omega 6 entirely, but to maintain a better balance between omega 3 and omega 6.

Omega 9

Omega 9 fatty acids are not technically essential, but they are still considered beneficial fats. They are found in foods such as olive oil, avocados, nuts, and seeds.

Together, omega 3, 6 and 9 can help form part of a balanced daily health routine.

The modern omega imbalance

Modern diets have changed significantly. Many people now consume higher amounts of omega 6 fats and lower amounts of omega 3 fats.

The British Nutrition Foundation guide to dietary fat explains the different types of fat and the role of unsaturated fats in a balanced diet.

This is often due to diets that include more:

• Processed foods
• Refined vegetable oils
• Packaged meals
• Fewer wholefood sources of omega 3

Omega 6 fats are not “bad” - your body needs them. The issue is balance. A healthy diet should include enough omega 3 fatty acids alongside omega 6 to support overall wellbeing.

This is one reason many people look for a balanced omega 3 6 9 supplement as part of their daily routine.

What happens if you don’t get enough essential fatty acids?

Because your body cannot produce essential fatty acids on its own, low intake over time may affect several areas of wellbeing.

Essential fatty acids help support:

• Brain function, as fats are important for normal cognitive health
• Heart health, particularly through omega 3 fatty acids
• Skin health, by helping maintain the skin’s natural barrier
• Nutrient absorption, especially for fat-soluble vitamins such as A, D, E and K
• General wellbeing, as healthy fats are part of everyday body function

This is why getting healthy fats consistently through food or supplementation can be an important part of a long-term wellness routine.

Omega 3 fatty acids foods: where can you get them?

You can get omega fatty acids from a variety of foods.

Good sources of omega 3 include:

• Flaxseed
• Chia seeds
• Walnuts
• Hemp seeds
• Oily fish
• Algae-based oils
• Cold-pressed plant oils

Good sources of omega 6 include:

• Sunflower seeds
• Pumpkin seeds
• Sesame seeds
• Nuts
• Certain vegetable oils

Good sources of omega 9 include:

• Olive oil
• Avocado
• Almonds
• Cashews
• Macadamia nuts

For many people, the challenge is not eating fats in general, but getting the right balance of high-quality fats every day.

Fish oil vs plant-based omega supplements

Omega supplements vary widely in quality, formulation, and source.

Fish oil is one of the most common omega supplements, but there are a few things to consider:

• Freshness
• Processing methods
• Quality and purity
• Sourcing
• Sustainability
• Taste and dietary preference

Fish obtain omega fatty acids from marine sources, which is why plant-based and algae-based options can also play a role in supporting omega intake.

A plant-based omega supplement may be a good option for people who prefer to avoid fish oil, follow a vegetarian diet, or want a more sustainable daily supplement.

What to look for in an omega 3 6 9 supplement

When choosing an omega supplement, quality and balance matter.

Look for a supplement that offers:

• A balanced combination of omega 3, 6 and 9
• Cold-pressed oils to help preserve nutritional quality
• Plant-based ingredients, where preferred
• Clear sourcing and manufacturing standards
• A format that is easy to take every day

Rather than focusing on one isolated nutrient, a balanced omega blend can help support your body more holistically.
