As a parent, winter has a very specific soundtrack: the cough from down the hallway, the sniffle that starts the night before daycare, and the “Muuuum, I don’t feel good” right as you’re trying to get everyone out the door.
It’s the season where you find yourself thinking about all the little things: sleep, food, sunshine, handwashing, warm layers, and whether their lunchbox came home untouched again.
Because while we can’t control every bug that comes their way, we can look for simple ways to support their growing bodies.
That’s where Bio Island comes in.
Bio Island’s kids range has been created with targeted nutrition and age-appropriate dosages to help support children’s health and wellbeing. And for winter, two products in the range are especially worth knowing about: Bio Island Zinc for Kids and Bio Island Cod Liver + Fish Oil for Kids.
Let’s get into it.
About Bio Island
Bio Island is an Australian-made family nutrition brand, with products developed to support families across different stages of life. The brand’s products are locally made in Australia, with ingredients sourced for quality and tested to meet health and safety standards.
For parents, the appeal is simple: the products are practical, easy to understand, and designed with children in mind.
Because when you’re standing in the vitamin aisle during winter, possibly wrestling a toddler at the same time, you don’t want to feel overwhelmed. You want to know what you’re reaching for, why it matters, and how it fits into the everyday rhythm of family life.
The Bio Island kids range includes vitamins, minerals, and nutrients designed to help support healthy growth and development.
Why winter nutrient support matters
Winter has a way of changing the whole household rhythm. Rain keeps kids indoors and routines get patchy, and parents are often juggling work, broken sleep, and that low-level winter worry that seems to sit in the background until spring.
Nutrient support isn’t about replacing a balanced diet, but about understanding which nutrients play a role in supporting their bodies, and knowing when a supplement may help if dietary intake is inadequate.
This was also the direction of Bio Island’s Kiindred campaign, which focused on helping parents understand key nutrients like cod liver oil, fish oil, and zinc in a broader winter health conversation, without making personal health claims.
Bio Island Zinc for Kids
Some nutrients get a lot of attention in winter. Others quietly do important work in the background.
Zinc is one of those.
Bio Island Zinc for Kids is a chewable tablet for children from 1 year+, formulated with zinc to support immune system health, cognitive function and healthy growth and development.
And because getting kids to take anything can sometimes feel like a full-body negotiation, the format matters. These come as milk-flavoured chewable tablets that can be chewed or crumbled, which is especially helpful for younger children who are still learning how to manage tablets safely.
Each tablet contains zinc gluconate 21mg, equivalent to 3mg of zinc.
For children aged 1–8 years, the directions are one tablet daily. For children aged 9–12 years, the directions are two tablets daily, or as directed by a healthcare professional. The tablets should be taken with a meal.
What we really like about this one is that it feels straightforward. It’s not trying to be everything. It’s a simple zinc supplement, designed for kids, that supports immune system health, cognitive function, and healthy growth and development when they may not be getting enough through diet alone.
For families, that kind of clarity is helpful. Especially in winter, when you already have enough tabs open in your brain.
Bio Island Cod Liver + Fish Oil for Kids
Now, this is the one for parents who love a multitasker.
Bio Island Cod Liver + Fish Oil for Kids contains vitamins A, D, and E, plus omega-3 fatty acids DHA and EPA, to help support healthy growth and development for infants and children.
Each capsule contains cod liver oil, which provides vitamin A and vitamin D3, as well as natural fish oil, which provides omega-3 marine triglycerides including EPA and DHA. It also contains vitamin E.
The capsules are fish-shaped softgels, which is a small detail but, honestly, a useful one. Anything that makes a supplement feel a little more child-friendly gets points from us.
For children under 5, Bio Island recommends cutting the capsule tail and squeezing the contents onto a spoon before administering, or squeezing the dosage onto food.
The directions vary by age: children 7–12 months can take 1–2 capsules daily, children 1–3 years can take 2 capsules daily, children 4–8 years can take 3 capsules daily, and children 9+ can take 4 capsules daily, or as directed by a healthcare professional. Infants up to 6 months should only use the product after consulting a healthcare professional.
This is a nice option for parents looking to support healthy growth and development with a combination of cod liver oil, fish oil, and key vitamins, particularly in those phases where food intake feels unpredictable, which is to say, many phases of childhood.
Because one day they love salmon, the next day they are deeply offended by the existence of dinner that isn’t strawberry icecream.
Why we love it
No parent can bubble wrap their child through winter.
Kids will still share drink bottles, wipe their noses on their sleeves, and will insist they are “not cold” while standing barefoot on freezing tiles.
But something is reassuring about focusing on the basics: food, rest, outdoor time when you can get it, handwashing, and thoughtful nutrient support where dietary intake may be inadequate.
Bio Island Zinc for Kids and Bio Island Cod Liver + Fish Oil for Kids both fit into that world nicely. They’re practical, parent-friendly, and designed to support growing children in simple, specific ways.
Zinc supports immune system health, cognitive function, and healthy growth and development. Cod Liver + Fish Oil for Kids supports healthy growth and development with vitamins A, D, and E, plus DHA and EPA.
And during winter, when family life can feel a little more chaotic, those small, steady supports can feel like one less thing to overthink.
Always read the label and follow the directions for use. Vitamins and mineral supplements can only be of assistance if dietary intake is inadequate. Do not exceed the recommended daily dose. Bio Island Zinc for Kids contains milk, glucose, sucralose and sulphites. Bio Island Cod Liver + Fish Oil for Kids contains fish products and sulphites, and is not suitable for those with a fish or shellfish allergy.
