But then why do we see improvements in people that get vitamin D + K2 supplements and not exercise?

As the article mentions, we pretty much don't see improvements with supplementation.

I don’t think there’s anything definitive. 400IU/day from one study is nothing if you’re deficient. 2000IU from another study is better, but even then we don’t seem to know much about absorption from these studies. For example, did it actually raise serum levels by 10ng/ml after a year, and how did THAT correlate to positive or negative health outcomes? K2 also seems to play an important symbiotic relationship with D, and seems notably absent from these studies.

		if supplements don't absorb and therefore don't affect health, there's no reason to take them.

From the article:

> the balance of evidence tips pretty clearly in the direction that people with low-ish levels would be wise to supplement

Yeah, I wish the article had brought Vitamin K2 into the mix since that seems trendy to pair with your D3 these days.
