Tonic Health Immune health being drunk on a tennis court

Get an easy shortcut to health with more energy, better mood & immunity. Get Tonic.

Staying healthy isn’t as hard as you think. The problem is, we often don’t look after our immune system with 77% of the USA having compromised immune health.

Tonic is all about empowering you with simple science, natural plants and vitamins to stay well. Because life is amazing and missing out sucks.
Your Immune health is powerful

Your body is insane. Power it with nature and you’re a force to be reckoned with. Forget about sugars, nasties, chemicals and fillers, Tonic is full of high-dose vitamins and clean ingredients. Drink it up for ultimate absorption - it’s the super-fuel your immune system has been waiting for

What's in your supplement microscope

We’ve got ultimate respect for medics, but we ask questions too. Like, what’s actually in those over-the-counter pills? And are they really helping us? We put honesty, research and a bit of healthy scepticism first.


One poor immune system, thousands of scientific papers, seven years of talking to doctors and immunologists. That’s how we learnt about immune health that actually works. Everything we’ve done has proof - you can read it here.

I used to spend every winter with a constant cold, missing out on life and work. As I began to research, I found the drugs we rely on aren’t what they seem.

I talked to leading figures in the medical industry and spent thousands of hours buried in scientific papers. What I found was too important not to share. With better immune health we can banish sick days and live life.

I’m a passionate believer in good nutrition. It’s key to keeping us fit and healthy. But life’s busy and it can be hard to get the levels of vitamins, minerals and plants that we need. Tonic is the perfect answer, a multivitamin drink that combines the latest science on vitamin dose with powerful plants.

I’ve got degrees in Biology and Clinical Nutrition and I’ve always believed in the power of the human body. I want to help others harness the strength of their immune system and Tonic is packed with the highest dose vitamins, minerals and plants to do exactly that.

Elderberry Sachet with real elderberry

Our high dose vitamin drinks were born from a blocked nose and a makeshift science lab in Sunna’s kitchen. Through years of research and testing (in real labs) we made Tonic clean, natural and plant-powered for max absorption.

We’re backed by science and are the highest dose all-in-one compared to anything else on the market. That’s what it takes to get your immune system up to full speed.

View of Trees in the forest green and sustainable

You've heard the stats on ocean plastic. Tonic partners with plastic gurus repurpose to get rid of twice as much plastic as we to produce whilst trying to remove plastic from our supply chain.

We're also carbon negative and seriously plant-positive. We work with environmental champions Brynk, tackling carbon emissions and planting trees. We offset twice the amount of carbon we produce and for every tree we use, we plant seven more.
