> They also recently went through a redesign

In my experience, this is often the cause of mysterious drops in search ranking. It's very easy to inadvertently introduce changes that negatively impact your ranking without even noticing.

At a quick glance, I noticed that many articles on examine.com link to hundreds of external references (e.g. more than half the page of https://examine.com/supplements/creatine/). In Internet Archive snapshots from before the redesign, these have the rel="nofollow" attribute, but on the current site, they do not. I'm not saying that's the cause, but it might be worth looking into exactly what changed in the redesign.

We removed rel=nofollow AFTER the rankings went down.

There are almost always drop offs when you redesign and Google reevaluates your content, sure add back in no follow if you like but Google is really clever. It sees every page on the site has changed to something else; if that is a recent change we’ll go with Occam’s razor here.

I guess I meant recent as in about 3 months ago. But hey maybe you should notify them of the issue
