We could see if there was a common thread.We would have to discount the placebo effect.Here goes:
Curcumin
Concentrated Omega 3
True food Natural VitaminE
Acetyl Lcarnitine&alpha lipoic acid marketed as Alpha(It is important to take these together...synergy)
True Food Maxi Q10 Only 120 mg(Only just started this because of expense)
Super antioxidant
Suitable cough medicine .
True food indicates it has been treated to maximise its potential
Amount taken is manufacturers maximum recommended dose except for cough syrup
All this costs a fortune but we think it worth a go. We will not really know if it is worth it for years
