Founded in 2019 by Sunna Van Kampen, Tonic Health was born out of Sunna’s frustration with frequently catching colds due to nutrient deficiencies and his inability to find products designed with optimal doses of vitamins without additives. Tonic Health is focussed on helping customers be healthier, which means their products claim to have maximum strength vitamin doses, without any sugar or additives. The Tonic Health brand has grown through social media, featuring content where Sunna offers advice on healthy eating. The London-based company’s supplements are now available in retailers including Sainsbury’s, Tesco, Asda and Holland & Barrett helping Tonic Health grow 3x in 2023.
