The makers of Abdomax claim to have tested their formula “over 300 different ways” to produce optimal results. Based on their research, the best way to take Abdomax is in the morning with a meal. The manufacturer also cites 11 studies on the Abdomax references page verifying the supplement works as advertised. We’ll review some of that research below.

In a 2019 study, researchers found psyllium husk – one of the largest ingredients in Abdomax – was linked to better intestinal microbiota balance in a group of constipated patients, compared to a control. Researchers told participants to take psyllium or a placebo over 7 days, and researchers found participants in the psyllium group were less likely to experience constipation and other gut health issues.

The makers of Abdomax also cite a 2018 study performed by the University of Illinois on walnuts and gut health. Researchers found walnuts contained special ingredients to impact the trillions of microbes or bacteria in your gastrointestinal tract, which could help walnuts support overall gut health. Walnuts also supported bile production and were connected to overall cardio, metabolic, and gastrointestinal health.

Oat bran, another important ingredient in Abdomax, could support gut health. In a 2018 study, researchers found oat bran improved nutrient digestibility, intestinal microbiota, and inflammatory responses in the guts of growing pigs. Pigs were given oat bran or a placebo over a 28 day period, and researchers observed lower inflammation, better nutrient digestibility, and other benefits in pigs in the oat bran group.

The makers of Abdomax also cite studies verifying the impact of plums, glucomannan, and aloe vera on digestive health. Plum and aloe vera are known for their natural laxative properties, for example, while glucomannan is a popular source of fiber that could promote homeostasis in your gut and extend the lifespan of beneficial gut bacteria.

Studies show pepsinogen is a powerful and abundant protein digestive enzyme secreted by your gastric chief cells as a proenzyme, then converted into pepsin, an active digestive enzyme, by gastric acid in the gastric lumen. Because of this effect, pepsinogen is one of the most important digestive enzymes produced by your body. Low pepsinogen levels are associated with constipation, poor digestive function, and other issues. It’s not totally clear how Abdomax raises pepsinogen levels in your digestive tract, and none of the cited studies specifically show the ingredients stimulating pepsinogen. Nevertheless, the makers of Abdomax are confident their formula works more effectively than medication or dieting to raise pepsinogen levels.

Overall, Abdomax is a digestive health supplement containing a science-backed blend of ingredients for gut health, digestion, and overall wellness.
