"This product is not intended to treat, prevent, diagnose or cure any disease or medical condition. Always consult a physician or medical practitioner before taking this product."
That is quoted often on many products - a legal 'get out'

I have no intention of consulting my doctor before I breathe, and I know it isn't a cure for anything.

I am occasionally breathless on exertion - this might help.
If it doesn't I wont buy it again.

Common sense has helped me live this long
