I think the concern is more towards products that does not function. Health products are turning to convenience already rather than "you should work towards your health". Everyone have so much money nowdays that they think they can buy health just from a bottle and some health devices.
About this health rock, magnet, patch thing. Sometimes it leaves to be desired. Some people may feel the effects. Some doesn't. But generally i think the effects is far too small for the price. You might be paying RM1000 for a product with 1% effect. Where you pay no money towards an ever increasing improvement towards your health by changing your lifestyle.
Sorry i for one knows the changes one does from popping pills and physically changing the habits towards health.
