this is interesting, thanks for sharing. It is very interesting. Now a lot of devices are produced by various companies that read the indicators of our body in order to improve our well-being, to respond to this or that disease much faster. On the page https://immunedefence.info/studies I read a very interesting study about various vitamins and vitamin complexes. Recently I discovered zinc which helps me a lot against colds. Zinc injected within 24 hours of the onset of symptoms shortens the duration of cold symptoms in healthy people. Did you know about this or not?
