Immune health is a system, not a switch. Sleep, nutrient status and gut health do most of the work, and none of them are seasonal.
The seasonal framing does immune health no favours. Your immune system is running continuously, and the things that support it are the same in July as in January. Treating it as a winter emergency means reaching for a quick fix at exactly the point where consistency would have helped more.
If you change one thing, change this. Sleep deprivation measurably reduces immune function, and no supplement compensates for a chronic deficit. Seven to nine hours is not a lifestyle preference, it is the maintenance window in which a lot of immune work happens.
Deficiency impairs immune function. Correcting a deficiency restores it. Going far past sufficiency does not keep improving things, and for some nutrients it causes problems of its own.
The ones worth knowing about:
A large share of immune tissue sits in and around the gut. Digestive comfort and immune function are not separate topics, which is part of why we started with a digestive product rather than an immune one. Fibre, fermented foods and a varied diet do more for this than any single capsule.
Regular moderate activity supports immune function. Very hard training without adequate recovery temporarily suppresses it. Both halves of that sentence are true and the second half gets left out a lot.
There is no ingredient that makes you immune to illness, and any product implying otherwise is overreaching. What you can do is remove the deficits, keep the basics consistent, and let the system do its job.
