The bottom line

Thorne makes some of the highest-quality supplements in the world, we actively recommend their B-complex, magnesium glycinate, methylfolate, and many others throughout suppdoc.io. Thorne is a brand; suppdoc.io is a recommendation engine. The two work together, not in competition. (Bonus: Thorne has its own quiz, but it's heavily oriented toward their own catalog.)
