PROMITOR® – what is it and why is it used in dietary supplements?

PROMITOR® is a patented soluble corn fiber developed by Tate & Lyle. It is a form of soluble dietary fiber that functions as a prebiotic in the gut and has documented effects on gut health, satiety, and blood sugar control.

But what makes PROMITOR® unique compared to other fiber sources? And why does Skytrition choose to include it in GuardUP?

Here, we go through everything you need to know.

What is PROMITOR®?

PROMITOR® is a patented and standardized soluble corn fiber from Tate & Lyle. It is created through the enzymatic treatment of corn starch and is classified as a soluble dietary fiber with prebiotic properties.

What makes PROMITOR® unique is its combination of:

• High fiber content – at least 70% dietary fiber per gram
• Excellent solubility – dissolves easily in water without lumps or cloudiness
• Neutral taste – does not affect the product's flavor profile
• Good tolerance – well-tolerated compared to many other fiber sources

How does PROMITOR® work in the body?

PROMITOR® is a soluble fiber that is not broken down in the small intestine but passes to the large intestine, where it is fermented by gut bacteria. It functions as a prebiotic – that is, nourishment for the good bacteria in the gut.

The effects include:

• Support for gut flora – increases the growth of beneficial bacteria such as Bifidobacterium and Lactobacillus
• Increased satiety – soluble fibers form a gel in the stomach that prolongs the feeling of fullness
• Smoother blood sugar curve – slows the absorption of carbohydrates and reduces blood sugar spikes
• Support for bowel regularity – contributes to normal bowel function

PROMITOR® as a prebiotic

Prebiotics are dietary fibers that selectively stimulate the growth of beneficial gut bacteria. PROMITOR® is clinically studied and shows prebiotic effects upon regular intake.

A healthy gut flora is linked to:

• Better immune function
• Improved nutrient absorption
• Reduced inflammation
• Better cognitive health via the gut-brain axis

Why is PROMITOR® relevant in a protein product?

High protein intake can sometimes negatively affect bowel function. Including a soluble fiber like PROMITOR® in a protein product helps to:

• Support gut health during high protein intake
• Increase the feeling of satiety and prolong the effect of the protein
• Contribute to steadier blood sugar levels
• Improve the overall nutritional profile of the product

When is it best to take PROMITOR®?

• With meals – for a steadier blood sugar curve and increased satiety
• As a nighttime protein – GuardUP with PROMITOR® works excellently as a nighttime snack for slow protein absorption and gut support overnight
• Daily – for continuous prebiotic support for the gut flora

In which Skytrition products is PROMITOR® found?

PROMITOR® is used in:

• GuardUP – Skytrition's slow-release casein protein, where PROMITOR® contributes prebiotic fiber support and increased satiety

What should you consider when choosing products with PROMITOR®?

1. The dose of PROMITOR®

Check how much PROMITOR® is included per serving. An effective prebiotic dose is usually 5–10 g per day.

2. Fluid intake

Soluble fibers work best with sufficient fluid intake. Make sure to drink enough water when you increase your fiber intake.

3. Gradual increase

If you are not used to a high fiber intake, increase it gradually to avoid temporary stomach discomfort.
