🍄 What Are 1-3, 1-6 Beta-Glucans? Baker’s Yeast Beta-Glucan Explained
Blog title: What Are 1-3, 1-6 Beta-Glucans? A Plain-Language Guide to Baker’s Yeast Beta-Glucan
Beta-glucan shows up on more and more supplement labels, usually written as “1-3, 1-6 beta-glucans.” If you have wondered what that string of numbers actually means, this guide explains it in plain language: what beta-glucans are, where they come from, and how they appear in a product like Zinzino Protect+. This is educational and factual, no health claims are made for beta-glucans here.
⚡ The Short Answer
Beta-glucans are naturally occurring polysaccharides, which are chains of glucose (sugar) molecules, found in the cell walls of yeast, certain mushrooms, oats and barley. The “1-3, 1-6” part describes the specific way the glucose molecules are linked together. Beta-glucans from baker’s yeast have a 1-3, 1-6 branching structure, which is different from the 1-3, 1-4 structure found in oats.
🔬 What the Numbers Mean
The numbers refer to the bonds between glucose units in the chain. It is simply a description of molecular structure, not a claim about what the ingredient does.
The main chain, where glucose units connect at the 1 and 3 positions.
Side branches linking at the 1 and 6 positions, giving the yeast form its distinctive branched shape.
Yeast beta-glucans are 1-3, 1-6 branched. Oat and barley beta-glucans are 1-3, 1-4. Different structures.
In supplements, the beta-glucans are typically purified from the yeast cell wall.
🍄 Where They Come From
The beta-glucans in many supplements, including Protect+, are purified from baker’s yeast (Saccharomyces cerevisiae), the same species used in bread-making. Extracting and purifying the beta-glucan from the yeast cell wall concentrates it into a consistent ingredient. Because it comes from yeast rather than an animal source, this form is suitable for vegans. In Protect+, beta-glucans are included as part of the overall formulation.
🍒 Protect+ as a Worked Example
Zinzino Protect+ is a focused, three-ingredient daily capsule built around 1-3, 1-6 beta-glucans from baker’s yeast, paired with two vitamins that do carry authorized nutrient roles. It is certified vegan by The Vegan Society. Here is how the three parts are described:
1-3, 1-6 beta-glucans purified from baker’s yeast. The signature component, included as part of the formulation.
From acerola berries, a whole-food botanical source of vitamin C.
From lichen, a plant-sourced alternative to fish- or lanolin-derived D3.
Read the label for the exact amount of each per capsule.
✅ What the Vitamins Are Authorized to Support
Unlike the beta-glucans, the two vitamins carry recognized nutrient roles, obtained at the intake stated on the label. Individual results vary from person to person.*
📋 How to Take It
Take one capsule daily, following the label directions. For adults.
A food supplement, not a substitute for a varied diet and a healthy lifestyle.
Certified vegan by The Vegan Society. Check the label for full details.
Check serving size, exact amounts and allergen information.
⚖️ Protect+ vs Xtend and Xtend+
If you are deciding between the immune range: Protect+ is the focused three-ingredient capsule. Xtend and Xtend+ are broader multivitamins (tablet and vegan capsule) with many vitamins and minerals plus a phytonutrient blend. Choose Protect+ for simplicity, or a broader formula for wider micronutrient coverage. Check each label.

❓ Frequently Asked Questions
What are 1-3, 1-6 beta-glucans?
Naturally occurring polysaccharides from yeast cell walls, where “1-3, 1-6” describes how the glucose molecules are linked and branched. Yeast beta-glucans have a 1-3, 1-6 structure, distinct from the 1-3, 1-4 form in oats.
Where do the beta-glucans in Protect+ come from?
They are purified from baker’s yeast (Saccharomyces cerevisiae). Because they come from yeast, this form is suitable for vegans.
Are beta-glucans vegan?
Yeast-derived beta-glucans are plant-suitable. Protect+ is certified vegan by The Vegan Society.
What is vegan vitamin D3 from lichen?
A plant-sourced form of vitamin D3 (cholecalciferol) derived from lichen, an alternative to fish- or lanolin-derived D3.
How do I take Protect+?
One capsule daily, following the directions on the product label. For adults.
How is Protect+ different from Xtend?
Protect+ is a focused three-ingredient capsule. Xtend and Xtend+ are broader multivitamins. Choose based on how much coverage you want. Check each label.
⚠️ Safety Notes
For adults. Read the label for the full ingredient and allergen declaration. Consult a healthcare professional before use if you are pregnant, nursing, under medical care or managing a condition.
