Action Heroes Pure Omega-3 Fish Oil Liquid


  • omega-3-liquid-for-kids-action-heroes-bare-biology

Hands down the most powerful and effective children's omega-3 available. 1ml contains the same DHA, the essential building block for brains and eyes, as a whole tin of sardines. It tastes great and is easily hidden in food. Parents can't believe the difference it makes.

Why Action Heroes omega-3 is the best: Fussy eaters? Always paranoid they’re not getting enough of those key nutrients? One of the many stresses of parenthood. When it comes to ‘brain food’, omega-3 is the original super food. For your little ones to benefit from an omega-3 supplement, it must have enough DHA (crucial for brain and eye development) and EPA, the two most important omegas which you’ll find plenty of in Action Heroes. 

Omega-3 content per dose:  one drop (1ml) has 500mg DHA and 130mg EPA.

Please note: For children over 12 a higher ratio of EPA to DHA is better so you could try our Life & Soul range.

Made from Wild, Sustainably Caught Fish: We only work with Norwegian fisheries and manufacturers certified by both Friends of the Sea and Marin Trust, the global responsible supply standard. 

We never use farmed fish and we also only use small fish such as anchovies, sardines and mackerel because they’re right at the bottom of the food chain, meaning they contain fewer heavy metals and other pollutants. Our fish oils don't contain iodine.

IFOS Certified For Peace Of Mind: Every batch is independently tested on top of the two sets of tests we carry out. This is our promise the oils we use are pure, fresh and safe. Our results for Action Heroes Fish Oil are published below.

Easily Digested: With no fishy aftertaste and a handy syringe to give them the perfect dose, Action Heroes comes in its natural triglyceride form which also makes it easier for the body to absorb. 

How much to take:  1ml is perfect for most age groups. See the TIPS FOR TAKING tab above for more info. 

Calories per dose: 12

100ml bottle: lasts 3 months if one child takes 1ml a day.

Packaging: 100% recyclable glass bottle.

Current batch & expiry:  batch AHL43910. Expiry date 27/06/2024.

Action Heroes is pure as pure can be, with no unnecessary ingredients like sugary flavourings:

  • Natural triglyceride-form fish oil from sardines and anchovies (smaller fish with fewer contaminants) 
  • Natural Sicilian lemon oil to give it a lovely taste  
  • A tiny amount of Vitamin E (tocopherol) to naturally preserve 

Each 1ml dose (100 per bottle) contains 500mg DHA & 130mg EPA.

Action Heroes is made in Norway, and flavoured and bottled in the UK. Our fish are sustainably sourced from clean, wild waters and FOS & IFFO-RS certified fisheries. 
Please remember that even with supplements like this one, children still need to run and play and eat their greens. Action Heroes is marvellous, but it isn’t magic.

And it’s always good to check with your doctor before using supplements like this one if your child:

  • is on any medication, such as blood thinners 
  • is about to have surgery   
  • has health concerns or conditions

Just 1ml a day of Action Heroes is a great amount of omega-3 for most ages, as long as they’re over a year old.  Babies over 6 months can safely have half a millilitre. You can tailor the dose depending on your child’s needs with advice from your doctor or nutritional therapist. We cannot advise on doses but the table below breaks down the omega-3 per amount of liquid.  Children over 12 can switch to Life & Soul as they’ll benefit from the higher amounts of EPA.

From our own personal experience and from the countless reviews we’ve received from customers, the health benefits from taking between half and 1ml of Action Heroes a day are incredible and support our view that it is not only safe but very beneficial for children who don’t get DHA from their diet.  The great thing about liquid form is the dosage can be varied and we always recommend parents consult a registered nutritional therapist for guidance.


It’s best to give Action Heroes to children at mealtimes. It’s easier to make it a fun habit this way, and the omega-3 is better absorbed alongside food.

Action Heroes tastes great – you can just pop a drop into your child’s mouth straight from the syringe. For the very reluctant, just mix it into anything cold: juice, a smoothie, yogurt or salad dressing.

Keep your bottle in the fridge once you’ve opened it.

It’s not the cost per bottle that matters when comparing omega-3. It’s the amount of the good stuff (EPA & DHA) you get for your money.

Here’s why Action Heroes is worth every penny.  It has the highest concentration of DHA you’ll find anywhere.

omega-3s (EPA & DHA) on average cost 69p a gram – Action Heroes is 43p a gram. A 120g tin of sardines costs 60p – a 1ml drop of Action Heroes is 30p.

When it comes to strength, taste, purity and cost, Action Heroes is in a class of its own. Still not sure? Here’s a direct comparison to help make up your mind.

A single 1ml drop of Action Heroes gives your kids 730mg of omega-3 and costs 30p.

Loved by kids. Approved by parents.

Every bottle of our Action Heroes comes with an optional syringe to help you measure the dose. 1ml of this supercharged oil provides your little one with 500mg of DHA, the same amount as a whole tin of sardines!
