  • "It's Changed Everything"

    I came to see Linda in desperation after suffering with low mood & other strange health problems - the Doctors tests all came back fine. I found Linda really on the ball - she instantly suspected what might be going on, and sent me off for some tests. Had I not, I would never have found out I have an unusual metabolic condition which means I will always need to supplement Vitamin B6 - it’s changed everything!”

  • "My joint pain is gone"

    I stopped eating the foods you said and of course my joint pain is gone already...looking forward to what the testing will reveal!

  • "I haven’t had a flair since!"

    My crohns consultant had told me to avoid fibre many years ago, which included all vegetables and fruit! Linda did a food intolerance test, then got me to reintroduce some ‘safe’ vegetables and instead remove some other foods which my intolerance test said i should cut out (like bananas). I haven’t had a flair since! I’m very pleased.

  • "My pain was completely gone"

    Linda sent me off for stool tests which showed my digestion was fine, but I had no lactobacilli bacteria. She recommended a specific probiotic, and within just a week my pain was completely gone and still is!
