An immune system that is constantly playing catch-up is neither fate nor a matter of character. There are reasons – and most of them can be measured. Before we talk about strengthening, we look properly: how is your vitamin D level really? Are zinc or selenium missing? Is there silent inflammation quietly using up resources? Is your body getting enough sleep to regenerate? From your values we build a picture, and from the picture, a plan.

Which building blocks make sense for you is decided by your values and the medical consultation.
