I had been suffering from cramps and the sciatic nerve for over 3 years until one day my sister recommended me to purchase the iron - Ionic Liquid Mineral and the Manganese - Ionic Liquid Mineral and oh boy let me tell you, this two combine have done miracles in my health. I do not suffer from cramping nor the sciatic nerve anymore, I can now sit down or walk without no pain. And check this out, it has only been three weeks since I started taking this Minerals. I definitely recommend this products 1000%
