Has anyone done a food sensitivity test?
I just did one where you send off some hair and they analyse it.
I know these are probably more in the realm of alternative than science, but has anyone else ever had one and followed the advice given in the results?
I have a lot of digestion issues and possibly mood issues (lethargy, low mood, lack of energy, focus etc) and it did point out some things I should avoid and am deficient in (creatine being one of them).
