  • From Devin Houston: Dosing Enzymes

    The amount of enzyme taken in a dose is dependent upon the amount eaten, not by age or body weight. No harm can come from taking "too much" enzyme. The more enzyme taken, the faster the food is broken down.

    It is preferable to give enzymes with the first few bites of the meal or just prior to mealtime (10 -15 minutes). But the important point is to take the enzyme, if not at the beginning, then during or after eating. Food stays in the stomach from 1 to 3 hours, therefore, introducing enzymes anytime during the meal will still provide benefits.

    Feel free to experiment with dosing to find the level that best suits your child?s individual needs. No toxicity or side effects have been found at any level of enzyme dosing.

    We recently added our Dosing Chart to the website. This may be helpful in starting a new product.

    Guest Column: Supplement-Drug Interactions


    I am Stephen J. Weiss, Pharmacist and owner of Nutrition Marketplace in Clive, Iowa. I will be writing columns in future newsletters and discussing topics of importance dealing with overall health for individuals in traditional and non-traditional ways.

    In today's society, a few physicians, as well as medical practitioners, are accepting non-traditional therapies. As we know, there is still a long road ahead.

    My reason for writing today is first of all, to offer free consultations to anyone interested, but most importantly, to make people aware that there can be conflicting issues between herbs, vitamins, supplements, etc... and prescription drugs. Since supplements can be purchased freely without prescriptions, most people consider them safe. To see if there are any interactions, please check with a qualified professional.

    We stock over 1600 supplements, including Dr. Houston's enzymes. If you have questions about supplement-drug interactions or want to suggest a topic for a future article, please contact me.

    Thank You,
    Steve Weiss
