Founded in 2017 by friends from Blackpool, Jack and Marcus, Zooki was created to tackle two key issues they perceived in the supplement industry: “low absorption and poor experience”. After a knee injury landed Marcus in hospital, he was advised to take omega 3 fish oil capsules. Left with fishy burps, the duo set their minds to creating something different. Since 2017, the business has grown to a team of sixty-two people, with products sold in over 50 countries, stocked in major retailers such as Holland and Barrett, Boots and Sainsbury’s. The company has grown from sales of £7.2m in 2023 to £20.1m in 2025.
