Vitamin Supplements

We try our best to keep this list up to date, but the constant influx of new drugs, medicines and research makes this task quite difficult. To be safe the following classes of drugs, medicines and other substances should be avoided if at all possible.

  • NSAIDS (Asprin, Ibuprophen)
  • Tylenol, paracetamol (acetaminophen), and drugs containing them.
  • Quinolones
  • Drugs metabolized through the liver or known to cause blood or liver related problems or hemolysis
  • Sulfa drugs
  • Petrochemically derived substances (This is a long list and gets longer every year. Many artificial foods, dyes and vitamins are included in this list.)
  • Moth Balls and anything containing naphthalene.
  • Artificial Food Coloring (Methylene and Toluidine blue)
  • Iron supplements. See The Dangers of Iron Overload
  • Ascorbic Acid. See Why is Ascorbic Acid on the Avoid List

Information PacketWhen in doubt, the safest course of action is to avoid the substance. If you react to something not on this list, avoid that substance in the future. Watch carefully for hemolysis signs at all times.
