If you are sensitive to perfumes or chemicals, then taking molybdenum supplements can help. I suggest taking 500 mcg or 1 mg a day. The least expensive high potency molybdenum supplement I have found is the Thorne molybdenum 1 mg(1,000 mcg). It is only around $6 for 60 capsules. Many other brands have supplements that are only 150 mcg, so it takes 7 of those to equal one Thorne capsule. Some people might want to divide the contents of the 1,000 mcg capsule and take it over two days.
