About Tolerance

Dedicated to helping those with food intolerances

We don't believe that having a food intolerance should be a barrier to being able to live well. From discovery through to daily management, we turn the science of intolerance into practical tips to enjoy more of the food and drink you love.

Why we built Tolerance

Food intolerances are far more common than people realise, but finding support can be challenging.

Tolerance is the brand that we wished existed when we were looking for our own answers, and we started with histamine intolerance because it's the most misunderstood. Since launching in 2024 we have worked directly with our network of nutritional practitioners and have been busy creating an ever-growing library of nutritional content to help people understand and manage their food intolerances. Just having a list of food to cut out doesn't cut it for us.

More recently we've partnered with Lifecode Gx to bring the gold standard of nutrigenomic testing to our customers. Understanding our internal wiring is often the first step to knowing how we can best adapt and overcome our dietary barriers.

Our founding team

Andrew Sears

Sean Golding

Andrew and Sean have both seen first-hand, through their families and their own experiences, how challenging discovery and management can be, both specifically for histamine intolerance and for food-related issues more broadly. Tolerance was built on their own lived experiences, and since then has grown from customers asking the same questions that they asked themselves.
