Several plant-based foods, such as onions, garlic, and artichokes, naturally contain fructooligosaccharides (FOS), a kind of prebiotic fiber. The health advantages of FOS have been investigated, including its potential as a nootropic supplement to improve memory, learning, and cognition. The nature, health advantages, recommended dosage, adverse effects, potential drug interactions, and the most responsible way to use this nootropic supplement are all covered in-depth in this article. We will also look at the chemistry of FOS and the physiological processes through which it affects the body and brain.

Nature of Fructooligosaccharides (FOS)

Prebiotic fibers called FOS are made up of chains of fructose molecules. They do not go through the body’s digestive process. Instead, they move to the colon, where they act as a food supply for good bacteria in the gut microbiome.

Health Benefits of Fructooligosaccharides (FOS)

Prebiotic FOS are naturally present in many foods, including chicory root, onions, garlic, and bananas. Instead of being digested in the small intestine, FOS travels to the large intestine where it becomes the nutrient for the bacteria there. Here are a few advantages to your health from ingesting fructooligosaccharides:

1. Better Digestive Health: FOS encourages the growth of lactobacilli and bifidobacteria in the gut, which can help to enhance digestion, lessen inflammation, and strengthen the immune system.

2. Enhanced Mineral Absorption: FOS can improve the body’s ability to absorb calcium, magnesium, and other vital minerals.

3. Lower Risk of Colon Cancer: FOS may lower the risk of colon cancer by encouraging the growth of advantageous bacteria and lowering the generation of dangerous chemicals in the colon.

4. Better Blood Sugar Control: By encouraging the growth of advantageous bacteria in the gut, this can lessen inflammation and increase insulin sensitivity, FOS may assist to improve blood sugar control.

5. Weight Management: By enhancing feelings of fullness and lowering calorie intake, FOS may aid in weight loss.

6. Increased Immune Function: By encouraging the development of advantageous bacteria in the gut and lowering inflammation, FOS may assist to boost immunological performance.

7. Lower Risk of Cardiovascular Disease: By enhancing cholesterol levels, decreasing inflammation, and controlling blood sugar, FOS may help lower the risk of cardiovascular disease.

Overall, ingesting fructooligosaccharides may provide a number of health advantages, especially for the immune system, digestive, and weight-management health.

Chemistry of Fructooligosaccharides (FOS)

A form of oligosaccharide termed fructooligosaccharides (FOS) is a carbohydrate made up of a few (often 3-10) monosaccharide simple sugar units. FOS is composed of terminal glucose units and fructose units connected by a (2-1) glycosidic bond.

Inulin, a polysaccharide present in many plants including chicory roots, onion, garlic, and Jerusalem artichokes, can be hydrolyzed by enzymes to produce FOS. The linear chains of fructose molecules that make up inulin also contain some terminal glucose units.

The terminal glucose unit and some fructose units are separated during the inulin’s breakdown by the enzyme inulinase, which is generated by some bacteria and fungi. This results in the creation of FOS.

Physiological Mechanism of Fructooligosaccharides (FOS)

Many physiological impacts of FOS on the body and brain have been demonstrated. To improve gut health and lower inflammation throughout the body, one of their main methods of action is to encourage the growth of advantageous gut bacteria. FOS achieves this by acting as a food supply for Lactobacillus and Bifidobacterium, two types of beneficial gut bacteria.

FOS can improve memory, learning, and cognition because they also have cognitive-enhancing properties. They achieve this by raising the amount of short-chain fatty acids (SCFAs) in the stomach, which have been shown to enhance memory and cognitive performance by encouraging the development of new brain cells and lowering inflammation. This secures a good gut-brain axis that allows the body to connect a bidirectional communication between the central and the enteric nervous system.


Optimal Dosage of Fructooligosaccharides (FOS)

The ideal FOS dosage to improve cognition is not yet known. Nonetheless, research indicates that daily doses of 5–15 grams might be useful. The quality and purity of FOS supplements might vary, and it’s crucial to remember that they are not subject to FDA regulation. Therefore, choose a high-quality supplement from a reputed provider as a result.

Side Effects of Fructooligosaccharides (FOS)

FOS are typically regarded as safe for the majority of individuals to ingest in meals. However, using FOS supplements may result in negative side effects like bloating, gas, and upset stomach. On rare occasions, using FOS supplements could result in an allergic reaction.

Potential Substance Interactions with Fructooligosaccharides (FOS)

FOS are normally thought to be safe for the majority of people to consume in food. However, using FOS pills which may interact with other substances and result in unfavorable side effects like gas, bloating, and stomach irritation. Hence, it’s vital to be aware of this possibility and speak with a medical practitioner to make sure there aren’t any potential interactions between FOS and your current prescription or diet.

Responsible use of Fructooligosaccharides (FOS)

The best way to use FOS responsibly is to pick a premium supplement from a reliable supplier. One of the best sources of FOS on the market, myPEAK PeakBiotic is a synergistic and highly bioavailable formulation. Together with other healthy ingredients like probiotics and prebiotics that can promote gut health and general well-being, it also contains FOS. It is crucial to use FOS supplements as directed by the manufacturer, and if you have any questions or concerns, consult a healthcare professional.


Fructooligosaccharides (FOS):


Fructooligosaccharides are very common in many foods and it is a type of prebiotic fiber that exerts prebiotic effects to improve your digestive health. Fructooligosaccharides work by inducing the growth of good microorganisms in the intestinal tract such as lactobacilli and bifidobacteria. With a better microbiome, the body will have better mineral absorption and a lower risk for colon cancer.

Fructooligosaccharides also decrease the cholesterol in the blood serum which decreases the risk of developing cardiovascular disease. MyPEAK PeakBiotic contains a sufficient amount of fructooligosaccharides and other compounds to exert a positive and synergistic effect on the health of the user. Hence, if you are planning to take MyPEAK PeakBiotic, please seek advice from the doctors to know the appropriate dosage for you.
