Overview

Source Naturals FOS is a dietary supplement built around fructooligosaccharides, or FOS, a group of naturally occurring carbohydrates. The formula provides 1,000 mg per serving and is presented in tablet form, with suitability for vegetarians stated by the manufacturer.

FOS are described as indigestible long-chain sugars that are intended to serve as food for beneficial intestinal flora. By supporting the growth of these “friendly” organisms, the supplement is formulated to help maintain a healthier balance of gastrointestinal bacteria. The source also notes that factors such as diet, stress, digestive issues, and antibiotic use may disrupt that balance.

According to the manufacturer, scientific research conducted in Japan has shown that FOS are selectively used by beneficial flora such as bifidobacteria and lactobacilli. This makes the product more specific than a basic fiber-style supplement, since it is positioned as a probiotic enhancer rather than a general carbohydrate source.
