Frequently asked questions about PGX®.

  • The PGX Capsules are awfully big, can I cut them in half and just use the insides instead?

    If you find the softgels to be too big, please don’t cut the softgels in half as the softgels contain an oily substance called medium chain triglycerides (MCTs). MCTs help increase metabolism and may help improve blood-glucose control. Also, cutting the softgel open could potentially be a choking hazard so it’s best to not use the softgels if you find them uncomfortable to swallow whole; you may wish to try PGX granulesas an alternative. PGX granules are very convenient to pour into a blender with other smoothie ingredients or to thicken sauces or add to baking. The PGX granules still retain all other benefits, including supplying highest viscosity fiber for the intestinal tract, providing a greater feeling of fullness.

  • After taking PGX, is it possible to still be hungry?

    Sure. It is possible to still feel hungry after taking PGX. It’s a gentle-acting plant fiber complex that works gradually to reprogram your neurological response to food. For emotional eaters, additional counseling and support may be necessary.

  • Does PGX contain Psyllium (a type of fiber)?


  • Is PGX safe?

    Yes. PGX is 100% natural and non-addictive. You can quit using it at any time. Extensive pre-clinical studies and clinical trials conducted in the United States, France, and Germany have found PGX to be remarkably safe for consumption, with no serious side effects.

  • Is PGX suitable for use by children?

    Although PGX is proven to be safe for adults, children have unique developmental and physiological needs, therefore a qualified health care practitioner is the best person to advise you in this matter.

  • What research is there to support PGX benefits and effectiveness?

    There is no maximum duration. It is recommended to take PGX for a minimum of 12 weeks. The PGX program™ can offer the tools and support for healthy weight loss and lifelong maintenance. Check out the PGX Programs to get started.

  • How does PGX lower the glycemic index of foods?

    By optimizing the rate of digestion and decreasing the rate at which sugars are released into the bloodstream. The higher the glycemic index of foods, the greater the lowering effect of PGX, up to 60%.

  • How do I know if my blood sugar is out of balance?

    Have your blood sugar levels tested by your healthcare practitioner to determine if they are above normal levels. The following may be symptoms of higher than normal blood sugar:

    • Cravings for sugary or high-carb foods
    • Low energy levels and mood swings
    • Increased appetite (especially sudden cravings)
    • Frequent or slow healing infections
  • How does PGX control cravings?

    Cravings are a direct result of blood sugar imbalance. PGX controls the release of sugars into the bloodstream, slowing digestion and creating a feeling of satiation.
