Preplex® is a prebiotic preparation in the nature of Acacia Gum and fructooligosaccharides sold as a component ingredient of prebiotic supplements, for medical and veterinary use.

Gum Acacia (Gum Arabic) is a dried plant that's derived from Acacia gum trees. Gum Arabic is a rich source of dietary fibers and in addition to its widespread use in food and pharmaceutical industries as a safe thickener, emulsifier, and stabilizer, it also possesses a broad range of health benefits that have been evidently proved. 

Gum Arabic is regarded as a prebiotic that enhances the growth and proliferation of the beneficial intestinal microbiota. It also helps extend shelf life, improves nutrition, and increases texture.

Fructooligosaccharides (FOS) serve as a substrate for microflora in the large intestine, increasing the overall gastrointestinal tract health. It has also been proposed as a supplement for treating yeast infections.

Several studies have found that FOS and inulin promote calcium absorption in both the animal and the human gut. The intestinal microflora in the lower gut can ferment FOS, which results in a reduced pH. Calcium is more soluble in acid, and, therefore, more of it comes out of food and is available to move from the gut into the bloodstream.
