PGX, the short-form of PolyGlycopleX, is a form of fiber that is sold either on its own as a supplement or as an ingredient in other dietary products from pills to shakes. Though there is no official website for PGX, a third-party website explained that the substance was first discovered by researchers at the University of Toronto in Canada. It was first tested at the Canadian Center for Functional Medicine in Coquitlam, British Columbia, Canada. A manufacturer’s website link was not provided.
In capsules of PGX, the following ingredients are often found: Amorphophallus konjac K, Koch root, Sodium Alginate, and Xanthan Gum.
Products containing this ingredient claim that this fiber is very soluble and is able to absorb approximately six hundred times its weight in water. This is why it must be taken with a full glass of water, as the entire reason that it may work is that it is consumed and then expands with water to promote a feeling of fullness. Furthermore, as a dietary fiber, it also promotes regularity.
The advantages of PDX are that if it does indeed function as it claims, then it may assist in providing temporary ease of weight loss as well as the elimination of waste from the body. This ingredient is heavily marketed and is available through several different independent retails and as an ingredient in several kinds of weight loss product.
The disadvantages are that there is no official or manufacturer’s website for PGX. The only information about this ingredient is available through independent sellers, which makes it difficult to find anything unbiased or official. No free trials of PGX could be found at the time of this review.
This product should only be taken with the recommendation of a doctor and with the guidance of this doctor, as it requires a significant amount of water intake and serious hydration issues could result if it is taken improperly.
With no manufacturer website and only unverifiable information available, it is unlikely that any doctor will recommend a product that contains PGX. Though fiber may be a healthy part of a nutritious diet, it is important to be able to understand the source of the fiber and know that it won’t have a dangerous impact on the body if not taken properly and with an adequate amount of water. Fiber is typically considered to be more healthy when it is obtained through natural sources such as fruits, vegetables, nuts, and whole grains.
