Hi, Luis! It's nice to meet you! Welcome to the NT Forums. I see MrsD has already responded to your post. You would heed well to follow her advice. She is very knowledgeable in the field of vitamin & mineral supplements, and holistic healing, as are some other members of the site. Get you a piece of paper and start following the links they give. I am sure you will learn a lot. Good luck to you, and very best wishes!

Richie
