Don't just take our word for it. Read our reviews!
The results are extremely thorough and we have certainly experienced an improvement in our health as a result of adjusting our diet. The follow up emails were very informative, which helped with our food choices.
Such an amazing service. It was quick and the results were really easy to read. It has really helped my daughter with what she can and can't eat.
Extremely useful - pointed out an intolerance to something I ate almost every day that has made all the difference
I am definitely feeling better already. Whether this is because I am following a dairy-free diet and, therefore, losing weight, or because I am intolerant to milk and have cut it out is yet to be decided but I am definitely getting less headaches so I am pleased so far.
