Security now, but there’s more recent info today. Today I take 5k D3, K2 Mk7, and a multivitamin several times a week, not every day. More in winter.

Result: not been sick more than a day or two for fifteen years. And rarely, once or twice a winter.

One exception, during covid I had it and it lasted five full days at medium intensity, then went away permanently.

This is not a “placebo effect” at all, was like turning on a light switch, immediate results. During the winter I heard about it, I’d been sick for almost three weeks straight, couldn’t shake it. Naysayers look silly in my opinion, or are perhaps an exception I mentioned above.
