If you’re on the hunt for the best diet pills that work, you may have come across PGX. This is the short form of PolyGlycopleX, a type 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 Fiber Supplement

When this PGX review was created, examples of ingredients that can be found in PGX capsule products include: Amorphophallus konjac K, Koch root, Sodium Alginate, and Xanthan Gum.

That being said, using the ingredients that are in the PGX Daily Ultra Matrix Softgels formula from InovoBiologic as an example, these include:

  • PGX (konjac- mannan, xanthan gum, sodium alginate)
  • Medium–chain triglycerides

The recommend dosage of this supplement is to take 1 – 2 softgels 3 times per day for the first week, 2 – 4 softgels 3 times a day for the second week, and 3 – 6 softgels 3 times a day in the third week and beyond. Softgels should be taken with a 200 – 500 ml glass of water but can be taken with or without food.

Products containing the konjac 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.

Supposed Benefits of This Diet Pill

Among the claims about PGX benefits include:

  • Decreases food cravings and provides a feeling of fullness
  • Supports healthy weight loss
  • Controls and balances blood sugar levels that are already within the normal range
  • Helps to maintain healthy cholesterol levels that are already within the normal range
  • Lowers the glycemic index of meals by as much as 60%

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.

PGX Pros

  • Variety of products – PGX is sold on its own or in other dietary supplements. For instance, the PGX InovoBiologic site advertised several PGX products, including softgels, a protein drink mix, granules, a whey protein and drink mix and daily singles. The many different options make it possible for just about anyone to fit this weight management aid into their lifestyle.
  • Easy to obtain – This ingredient is heavily marketed and is available through several different independent retailers and as an ingredient in several kinds of weight loss product.
  • Temporary weight loss – 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.

PGX Cons

  • Not all fiber is the same – 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.
  • Sufficient clinical evidence is lacking – The diet pills that work the best are those that contain ingredients that have been clinically studied and the clinical studies have found evidence that they may be beneficial for weight management in some way. This is the not the case for PGX. A systematic review of randomized clinical trial involving PolyGlycopleX concluded that there was no indication that PXG intake leads to reductions in body weight.
  • Dehydration is a risk – PGX 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

Due to the lack of evidence that this diet pill is safe or effective for weight management and that it may only lead to temporary weight loss at best, it is recommended that you speak with your healthcare professional prior to taking PGX to make sure it is a sensible option for your weight management goals.

Hi I’m on the atkins diet ,type 2 diabetic take high blood pressure pills and pills for type 2 dibetis so I’m wondering if pgx will do any harm ? Thanks Bob.

I really think you should ask your doctor about that, Bob. I wouldn’t think that a high fiber pill would cause any harm, but it might have other ingredients in it that could cause conflicts that you don’t realize. Try printing off an ingredients list and popping over to a pharmacist or doctor to ask.

PGX doesn’t do anything. I would never buy this again

I wonder why it didn’t work for you. I had great results. Did you use it every day according to the directions? Did you use the maximum dose?

I saw PGX diet pills in a magazine that I was reading and I liked the way they looked. I bought them at the drugstore near my house – although I found out that they are cheaper online – and am very happy with the results. I think these are fast and healthy for losing weight. I don’t have a scale but my clothes are looser. That’s how I can tell that I’ve lost weight.

PGX diet pills are a disaster. I don’t think that they’re anything but a diuretic because I was headed to the bathroom constantly, and though I did lose weight pretty quickly at first, I didn’t lose anything after the first week, and the weight actually started to climb back on. I’m guessing that it was just water weight that was lost at the start and that began to return to normal again once i started to rehydrate. To me, this seems like more danger and hassle than it’s worth.
