Basis: Na2MoO4 x 2H2O, dihydrate (MW 241.96; anhydrous would be 0.466) -- hydration state on labels not stated, dihydrate assumed as the common commercial form
Why this tier: Turnlund's isotope study measured absorption of dietary molybdenum (88-93%) but did not compare supplement forms. No head-to-head human bioavailability or efficacy comparison of this form was located in PubMed searches.
