We carry a number of other, non-enzyme supplements purely as a convenience for our customers who wish to purchase from one site.  These supplements are not formulated by Dr. Houston, but are produced by Reliance Vitamin, a high-quality manufacturer using organic materials when possible and no artificial colors or flavorings.
