What Is Kestose? Let's Cover the Basics

What Kestose Is and How It Works
Kestose is a type of fructooligosaccharide and is known as a naturally occurring oligosaccharide.
It is found in small amounts mainly in fruits and vegetables such as bananas and onions. By serving as food for beneficial gut bacteria, it is expected to help support a healthy gut environment.
It is not easily broken down by digestive enzymes, so it can readily reach the large intestine.

How It Differs from Other Oligosaccharides
Compared with other oligosaccharides, kestose is said to be relatively effective at supporting beneficial bacteria such as bifidobacteria.
Common oligosaccharides, such as galactooligosaccharides and isomaltooligosaccharides, can also help support a healthy gut environment, but kestose is particularly notable for supporting beneficial gut bacteria, including bifidobacteria and butyrate-producing bacteria.
It is also mildly sweet and low in calories, making it easy to consume regularly.

|---|---|
| Kestose | Supports bifidobacteria; low in calories |
| Galactooligosaccharides | Supports a broad range of beneficial bacteria |
| Isomaltooligosaccharides | Sweet; supports a healthy gut environment |
The Role of Kestose in Gut Health
By helping beneficial bacteria do their job, kestose is expected to support a balanced gut microbiome.
