I've had success taking a combination of vitamins D3 and K2 in liquid dropper form. I noticed the benefits more than when I was just taking capsules of D3.

Interestingly, I've managed to avoid getting a seasonal cold this year unlike most of my coworkers and friends, and my guess is that the D3/K2 has helped with that because I haven't changed much else.

There are billions of things that have changed this year compared to last year and you're attributing your lack of getting a cold to Vitamin D?

Anedote. I became a vegetarian and started 10,000 unit daily vitamin D supplementation this winter. I've also experienced cold after cold. My nose is a river. Body aches, fevers. So has my family, and our friends' families.

So by the logic of the other children of the parent I should quit my vitamin D supplementation, and probably avoid friends that take Vitamin D. ;-)

Purely anecdotal, but same story here. D3 only, vegetarian. I can't think of a single point in my life where I didn't get sick (cold/flu), if I was surrounded by sick people. This year, 8 sick people in my house and extended exposure with my wife sick for two weeks. I'm still fine.

> Purely anecdotal, but...

It’s not just anecdotal, it’s bad reasoning. You can’t prove that your supplement prevented you from getting sick. Maybe you were immune to whatever was going around. Maybe you didn’t touch your face at the right times. Maybe you washed your hands really well. There are thousands of possible explanations, and it’s misleading and wrong to attribute it to some random supplement.

Please stop doing that. It’s the same reasoning people use when they say that they prayed and God answered. Just because B happens after A doesn’t mean that A caused B; it just means B happened after A.

This is where you committed a fallacy for a change. Next time be more careful! With this kind of thinking you'd rule out any causality.
