I have a question about supplements that you buy from the average health store, 90% use an excipient called 'Magnesium stearate' is this safe? From what I understand it used in the mass production of tablets to keep the machines from clogging up. http://www.nutritionalsupplementsandvitamins.com/html/stearic_acid_in_vitamins_and__.html http://www.drrons.com/beware-additives.htm
