Thank you 😊
Quick results and clear understanding of what foods I should not be eating. I have since enjoyed better health and with that peace of mind that I am eating foodstuffs that agree with my body type
Super helpful, knowledgeable and informative.
Now I know what to avoid and what to enjoy thanks to their help.
The result came back very quick and easy to read, your client service is amazing too, thanks to Susan!

I bought a food tolerance test, the kit arrived in a few days and my results arrived within a week. I’ve since cut a few things out of my diet and feel much better for it. Definitely recommend getting tested.
I ordered food intolerance tests for two of my kids who were suffering in different ways and at their wits end as to how to deal with what was going on in their bodies. All the helpful advice from family, friends and dr google had them totally confused and I had always been put off by the daunting price tag of “proper” intolerance tests.
Swan science made it so easy and offers testing that is as good as any other lab and incredibly good value for money - the results came back quickly, were easy to read and highlighted foods to avoid that we would never have thought of.
A brilliant service and a game changer for anyone that is struggling with intolerance issues or is just not sure and wants to look at this with some proper scientific testing.
The Swan Science intolerance test was simple to do at home, results came back fast, and the report was clear and helpful. Definitely worth it for understanding food sensitivities better.
Really pleased that I undertook the intolerance test. It was simple and straightforward to order online and then to complete when the pack came. Instructions were very clear and the test results were laid out really helpfully. I have now cut out yeast from my diet, as the test highlighted this as a high intolerance for me, and I am feeling much better. Thank you!
Really easy to use website, very clear. Didn't wait long for the package to arrive, clear instructions. Just post back via the post office. Received an email with my results within a few days. They are very helpful if you need to ask a question. Would highly recommend.
Super easy to follow instructions & unbelievable fast results, very interesting result something I have never considered having an intolerance too but will adjust my diet accordingly.
Would not hesitate to recommend!
Quick and easy test - fast results. Thanks.
Super quick service and easy to to interpret results. Am looking forward to trialing it out and seeing what difference it makes.

I ordered 2 tests for myself and my partner as we have varying food issues.
The tests arrived quickly, the instructions were easy to follow and the results arrived in less than a week.
We’ve found the results really insightful based on our normal eating habits.
Now I have more understanding of the test, and how it works, I want to do another one after having a super varied diet for a couple of weeks so I can get a full scope reading of as many of the 200 food types as possible, including some of my ‘issue’ foods as I haven’t eaten some items for a few years meaning they didn’t show a reaction on my test.

I took a food intolerance test provided by Swann science. The whole process was very well explained and any questions I had were answered or explained fully and promptly. The test tested over 200 food types and the results were returned to me via email within two days. All in all a speedy trustworthy service that I wouldn't hesitate to use again.

Absolute game changer for me! Had no idea what I was intolerant to and this test has made such a difference to my life. No more bloating, acid reflux, feeling sick and exhausted from my diet.
