Manufacturers use fillers. It saves money. Avoid Common fillers: polyvinyl alcohol, talc, polyethylene glycol, calcium, magnesium sterate, titanium dioxide, odium benzoate, sodium molybdate, hydrogenated palm oil, calcium stearate, potassium chloride and calcium carbonate. Overexposure to these metals and minerals can suppress the immune system and pump toxins into your system. Ironically, you’re probably using these products to feel better, but you could be making yourself worse.
