Xylose Isomerase

Why You Need It

• Balances Blood Sugar: It helps regulate how quickly sugar enters your bloodstream.
• Boosts Gut Health: It acts as a prebiotic, feeding good bacteria.
• Reduces Sugar Cravings: By stabilizing glucose, it helps curb the urge to snack.
• Increases Mineral Absorption: It can bind to minerals, making them easier for your body to absorb.

Deep Dive

Xylose Isomerase is an enzyme that catalyzes the reversible conversion of xylose to xylulose and glucose to fructose. Why does this matter to you? When you eat carbohydrates, this enzyme helps break them down into a form that your body can use for steady, sustained energy rather than a rapid spike and crash.

For those with sensitive stomachs, Xylose Isomerase is often used to digest sugar alcohols (like xylitol and sorbitol) found in "sugar-free" products. Without this enzyme, these sweeteners can cause bloating and gas. By taking it, you can enjoy guilt-free treats without the digestive discomfort. Furthermore, in its bound form (often called Xylo-oligosaccharide or XOS), it acts as a potent prebiotic, significantly increasing bifidobacteria in the gut, which is essential for immunity and digestion.

Natural Food Sources

While Xylose Isomerase is concentrated in supplements, you can find it naturally in foods, particularly fruits and certain starches. However, processing often destroys the enzyme, so raw sources are best.

Supplementation

• When to take it: Look for supplements labeled Xylose Isomerase or XOS (Xylo-oligosaccharide).
• Dosage: Clinical studies suggest a dose of 1.5g to 3g per day for metabolic and gut health benefits.
• Who should take it: Individuals with blood sugar management issues, those consuming sugar alcohols (keto dieters), or anyone wanting to improve their gut microbiome.
