What you need to know

Omega-3 is one of the most important building blocks of your child’s brain and body. With 500mg of DHA per drop, this liquid fish oil for kids is the most powerful you’ll find. It’s certified sustainable, pure, and fresh. Lightly lemon-flavoured, kids do take it, plus it’s easy to hide in cold food and drinks.

Tips for taking

How much?

From our experience with our kids and countless customer reviews, the health benefits of taking 0.5ml from 6 months to a year and then 1ml from 1 year onwards are incredible.

When and how?

It’s best to take at mealtimes. Just use the syringe included and squeeze a drop into your child’s mouth, under or on the tongue. For the very reluctant, mix it into anything cold: juice, a smoothie, yoghurt or salad dressing. Give it a funny name, and follow it with a treat or piece of zingy fruit. Worried? Read our reviews from hundreds of parents. They’ll reassure you.

What if I’m worried?

If there's a specific health concern, we recommend parents consult a registered nutritional therapist for guidance. We love Lucinda Miller at NatureDoc, who knows kids inside out.

Full Ingredients

• Pure fish oil (from certified sustainably sourced sardines, anchovies and mackerel)

It’s always good to check with your doctor before taking an omega-3 if your child:

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

Why Action Heroes is different

  • Super strength for fast results

    The strongest kids’ omega-3 on the market, so you see faster results. Plus, it’s the best value per dose.

  • Hundreds of nutritionists recommend it

    Over half of our sales come from nutritional therapists, doctors and experts who are very selective about supplements, see the real-life changes, and recommend us.

  • IFOS certified purity

    All our finished batches are tested by International Fish Oil Standards – the most rigorous benchmark for purity and freshness. On top of the two sets of tests we also run because we’re omega-3 perfectionists.

  • Wild, sustainably caught fish

    Our long-time Norwegian manufacturer only works with fisheries certified by both Friends of the Sea and the Marin Trust

    Omega-3 Fish Oil

    First of all, what a lovely designed label.

    I have been giving my kids this fish oil for about 2 months. I just give it to them straight and they seem to take it just fine. I believe it is good quality and worth the money for pure and non toxic children’s vitamins. Thank you!

    working!

    I have to ensure we give our children this every night, as I think it's making a difference. I was told recently at a parent's evening, that our son had really started to knuckle down and concentrate, someone who has always been 'busy' usually, maybe it's a coincidence? But we've been using it since Nov last year and he's made a vast improvement since then. And anyhow, even if it is a coincidence, what's the harm, it's only going to be beneficial for my two - so I will keep on using it for a long as possible.
