You can't "boost" your immune system with "health food," nor would you want to

[popobawa4u]

I always wondered whether they mean “boost” as in to enhance, or to steal.

Those randos just boosted my immune system! I swear I left it right here!

I outlined the remedy in another post today:

Stop taking "probiotics"

There is actually an easy all-purpose solution to this and many other food, medicine, and supplement problems. Do away with all “claims” completely. No marketing allowed. Just do purity checks like there are for lab reagents so that customers know exactly what they are buying. Then it is their responsibility to do their homework to buy and use what they need.
