Supplement Category: Cost per Dose and Clinical Evidence

verifiedsupplementdata/supplement-category

Returns what Verified Supplement Data publishes for one supplement category: the supplement form, the clinical dose and its upper limit where one exists, the conditions it is studied for, a summary of the clinical evidence per condition with PubMed references, how the cost per serving and per effective daily dose is calculated, and every product tracked in that category (brand, serving size, servings per container, list price, Amazon offer price and the date it was checked, cost per serving, cost per effective daily dose, certification, label database id). The category is one of 14: biotin, calcium-citrate, collagen, coq10, creatine, iron-bisglycinate, magnesium-glycinate, methylfolate, multivitamin, omega-3, protein, vitamin-b12, vitamin-c, vitamin-d3. Each answer keeps the publisher's licence (CC BY 4.0) and source fields; credit Verified Supplement Data, https://verifiedsupplementdata.com.
