Tonic Health Daily Immunity Raspberry and Lemon

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.
