Health Benefits of PGX

PGX (PolyGlycopleX) is a proprietary dietary supplement that contains polysaccharides (a type of carbohydrate). Typically touted as a natural weight-loss aid, PGX is said to suppress the appetite and reduce food cravings. PGX is also marketed as a fiber-rich supplement that can help with certain health conditions.

In addition to using PGX for weight loss, some consumers take PGX supplements to keep their cholesterol in check. Proponents claim that taking PGX can lower your levels of LDL ("bad") cholesterol.

PGX is also said to fight diabetes by regulating blood-sugar levels and protecting against insulin resistance.

So far, research on the health effects of PGX is limited. However, there's some evidence that PGX may offer some benefits. Here's a look at key findings from the available studies:

1) Weight Loss

PGX may influence certain hormones involved in controlling satiety (the feeling of fullness), according to a 2010 study in the European Journal of Clinical Nutrition. For the study, 54 healthy adults took either PGX or a placebo for 21 days. By the study's end, members of the PGX group showed a significantly greater increase in levels of satiety-related hormones (compared to members of the placebo group). However, the study's authors noted that PGX may have a different effect on overweight people.

2) Diabetes

PGX may aid in blood-sugar control (a key element of diabetes management), suggests a 2010 study in the European Journal of Clinical Nutrition. In a series of experiments involving 10 participants, researchers found that PGX helped reduce post-meal spikes in blood sugar.

In addition, PGX appeared to help lower cholesterol levels, body weight, and food intake.

PGX is known to cause a number of minor side effects, including gas, bloating and constipation. Little is known about the safety of long-term use.

Keep in mind that supplements haven't been tested for safety and due to the fact that dietary supplements are largely unregulated, the content of some products may differ from what is specified on the product label.

Widely available for purchase online, PGX is sold in many natural-food stores and in stores that specialize in dietary supplements.

Due to the lack of supporting research, it's too soon to recommend PGX for any health purpose. If you're considering using it, talk with your doctor first. Self-treating a condition and avoiding or delaying standard care may have serious consequences.
