Omega 3 for Kids: Essential Benefits and Sources

Posted by Team OO on

Omega-3 fatty acids are essential fats that play a crucial role in the growth and development of children. These fats are not synthesized by the human body and must be obtained through diet or supplementation.

They are vital for the development of the brain and retina, particularly in the early years of life, and continue to support cognitive function and overall health throughout childhood.

Studies indicate that omega-3 supplementation could be beneficial in enhancing self-regulation in preschool-aged children. The Omega Kid Study suggests investigating this effect by examining the role of omega-3 long-chain polyunsaturated fatty acids in the diet of young children.

Self-regulation is a foundational skill that can impact a child's attention, behaviour, and emotional well-being, proving integral to their successful development.

Whilst research on the long-term outcomes of omega-3 supplementation is ongoing, early indications show potential benefits that extend into later stages of childhood.

As children develop and encounter various cognitive and emotional challenges, maintaining adequate omega-3 levels could be a supportive measure for their ongoing mental health and academic performance.

Understanding Omega-3s and Their Importance for Children

Omega-3 fatty acids are essential for children's growth and development, particularly for the brain and central nervous system.

Accurate knowledge of DHA, EPA, and ALA, the main types of omega-3s, is vital for understanding their role in paediatric nutrition.

The Basics of Omega-3 Fatty Acids

Omega-3 fatty acids are a group of polyunsaturated fats that are crucial for human health.

There are three main types: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA).

These are deemed essential fatty acids because the body cannot synthesise them; they must be ingested through diet.

Sources of omega-3s include oily fish and plant-based foods like flaxseeds and walnuts.

Significance of DHA and EPA for Development

DHA and EPA are particularly important for the developing brain and central nervous system in children.

DHA contributes to brain health by supporting neuronal function and visual acuity. Furthermore, EPA plays a supportive role in reducing cellular inflammation.

Together, DHA and EPA are pivotal in ensuring proper growth and development in infants and children, influencing cognitive function and behavioural health.

ALA's Role in Children's Nutrition

Although ALA does not directly contribute to brain structure, it is a necessary precursor to EPA and DHA production in the human body and can also provide energy.

ALA is found in plant-based sources such as seeds and nuts. While the body can convert ALA to EPA and DHA, the process is not highly efficient in humans.

Therefore, direct sources of DHA and EPA are recommended. Nonetheless, incorporating ALA through diet is an important aspect of providing a balanced intake of omega-3 fatty acids for children.

Dietary Sources of Omega-3 for Kids

Ensuring children receive adequate omega-3 fatty acids is crucial for their development. These essential fats are not produced by the body and must therefore come from dietary sources.

Fish and Seafood High in Omega-3

Fatty fish such as salmon, tuna, and mackerel are rich in omega-3 fatty acids and are excellent food choices for children.

  • Salmon: A 3-ounce portion contains significantly high levels of omega-3 fatty acids.
  • Tuna: Offers a convenient option for omega-3 intake, though it should be consumed in moderation due to potential mercury content.
  • Mackerel: Another oily fish that provides a healthy amount of omega-3 fats.

It is recommended for children to consume at least two servings of oily fish per week to meet their omega-3 requirements.

Plant-Based and Alternative Omega-3 Options

For those following a vegetarian or vegan diet, plant-based sources of omega-3, such as flaxseeds, chia seeds, and walnuts, are valuable alternatives.

While these contain ALA, a precursor to the omega-3 fatty acids found in fish, it’s important to note that the conversion rate to EPA and DHA is relatively low.

  • Flaxseeds: Can be ground and added to cereals or smoothies for an omega-3 boost.
  • Chia Seeds: Easily incorporated into a variety of dishes, providing both fibre and omega-3.
  • Walnuts: A handful of walnuts can contribute a significant amount of ALA to a child's diet.

Algae oil supplements are another viable source of EPA and DHA suitable for children who do not consume fish. They offer a direct supply of these essential fats, bypassing the need for conversion like plant-based sources.

The Role of Supplements in Omega-3 Intake

Ensuring adequate omega-3 intake is crucial for children's development. Supplements can play a vital role when dietary sources are insufficient or in cases of specific health considerations.

Omega-3 Supplements and Their Formats

Omega-3 supplements come in various formats, catering to different preferences and dietary restrictions.

Fish oil supplements are amongst the most common, providing both DHA and EPA, crucial types of omega-3 fatty acids.

For vegetarians or those with fish allergies, algae oil presents a viable alternative, primarily offering DHA.

Additionally, cod liver oil is an option, although it typically contains lower levels of omega-3s and higher amounts of vitamins A and D.

Choosing the Right Omega-3 Supplement

Selecting a suitable omega-3 supplement necessitates considering factors like purity, sustainability, and the presence of additional vitamins and minerals that may be beneficial or necessary for individual health requirements.

Labels should be read carefully to check for certifications that guarantee these qualities.

Consulting with a healthcare professional is recommended to make an informed choice and to understand how a supplement could interact with individual health circumstances or other medications.

Optimal Dosage and Safe Use

The optimal dosage of omega-3 supplements varies by age, health status, and existing diet.

While there is no one-size-fits-all dose, guidelines are available that suggest appropriate amounts for different age groups.

Parents must be mindful of these recommendations to ensure safe use.

It is crucial to adhere to advised dosages unless a healthcare professional suggests otherwise, as exceeding the recommended dose may lead to adverse effects.

Benefits and Potential Side Effects

Omega-3 fatty acids are regarded for their role in brain function and early cognitive development, and their supplementation is often considered for children due to potential health benefits. However, awareness of possible side effects is essential to ensure safe usage.

Cognitive and Physical Benefits

Omega-3 fatty acids, notably found in fish oil, have been associated with enhancements in brain function, including memory and learning capabilities in children.

For instance, studies suggest that omega-3 can play a crucial role in brain development and may alleviate symptoms related to attention deficits and hyperactivity.

Supplementation of omega-3 in children has been investigated for its possible benefits in managing ADHD symptoms, with some research showing a small but statistically significant benefit.

Furthermore, with depression being a critical concern in child and adolescent health, omega-3 may also offer therapeutic benefits in childhood depression, improving mood and sleep quality.

  • Brain Function: Essential for neurodevelopment and daily cognitive processes.
  • Growth: A key component in overall physical development.
  • Attention and Hyperactivity: May reduce symptoms of ADHD.
  • Mood and Depression: Potential to improve mood and mitigate depressive symptoms.

While omega-3 supplements are generally considered safe, they may induce side effects in some individuals.

Commonly reported adverse reactions include bad breath, nausea, an unpleasant aftertaste, and headaches.

More infrequent gastrointestinal issues like diarrhoea, loose stools, or indigestion can also occur.

Parents should be cautious about allergies and potential interactions with other medications their children may be taking.

Establishing a Balanced Omega-3 Enriched Diet

Omega-3 fatty acids are vital for children's growth and brain development. A balanced omega-3 enriched diet can contribute significantly to heart health and learning capabilities in kids.

Incorporating Omega-3 into Daily Meals

To ensure children receive adequate omega-3s, their diet should include a variety of seafood, particularly oily fish, which is a rich source of docosahexaenoic acid (DHA).

For children who do not eat fish, options such as flax seeds, chia seeds, and walnuts are excellent plant-based sources. These can be easily added to breakfast cereals or smoothies.

A serving of fish two times a week and daily inclusion of nuts and seeds can meet the recommendations for omega-3 intake.

For cooking and salad dressings, vegetable oils such as flaxseed oil or walnut oil boost omega-3 content in meals.


Integrating omega-3 rich foods into a child's diet can be simplified with minor adjustments:

  • Swap regular milk for omega-3 fortified milk at breakfast.
  • Include a small handful of nuts as a snack or part of lunch.
  • Serve seafood meals tailored to children's taste preferences to encourage healthy eating habits from an early age.

Consultation with Health Professionals

Before making any significant changes to a child's diet, it is crucial to consult with a healthcare professional.

They can provide guidance on appropriate servings and ensure that the nutritional needs are tailored to the child's age and growth requirements.

Professionals can also advise on suitable vitamins and supplements if diet alone does not meet the needs for omega-3.

This advice is particularly important for children with specific health concerns or allergies to standard sources of omega-3.


Seeing a healthcare professional ensures that dietary changes support overall health and address any individual requirements for brain and heart health.
