Pairs

Two at once, and what is known about it.

1,574 combinations have a page. 93 of them have been given together in a trial by somebody, and we have read and scored the trial for 93 of those so far. The other 1,481 have never been tested as a pair at all, which is most of what there is to know about taking supplements together.

And the other 87 that have been tested

The ones people search for are first, with how often. Below those, search volume has not been measured and the order is alphabetical rather than a ranking of nothing.

Why most of them are empty

Of the 1,574 pairs with a page, 1,481 have never been tested together by anybody. That is not a gap in our reading. It is what the research looks like: trials are expensive, and testing two supplements together costs more than testing one, so almost nobody does it.

The ones people search for most are drawn out on never tested together. Every pair here, tested or not, carries the search we ran, its date and its hit count, so you can see what we looked for.
