Last year, the FDA announced the approval of Endari, a drug for sickle cell disease. Endari is an oral powder comprised of L-glutamine, an important amino acid currently available as a supplement. The drug company, Emmaus Medical, Inc., filed an investigational new drug (IND) application—demonstrating their investigation of L-glutamine as a drug. If a drug company begins investigating a nutrient for use in a drug before a supplement company files an NDI notification on that nutrient, the company can ask the FDA to have supplement version removed from the market, leaving consumers with no other option than the drug. Currently, a 120-pill bottle of L-glutamine can be purchased for less than $10; a year’s worth of Endari will reportedly cost consumers more than $40,000. CBD oil faces a similar threat.
