Why Oat Beta-Glucan Used as a Dietary Supplement for Pet
Oats, specifically oat bran, serve as the primary source of beta-glucan in pet supplements. Manufacturers prefer β-glucan extracted from oats because it is highly bioavailable—meaning pets can easily absorb and utilize it. The structure of the oat grain allows the outer layer to contain a significant concentration of beta-glucan, where most of the soluble fiber resides. Besides oats, other grains like barley, as well as certain yeasts and fungi, can also provide beta-glucan. However, oat-derived oat beta-glucan as a dietary supplement for dogs has a reputation for being particularly effective in supporting digestive and immune health in pets.
What is Beta-Glucan?
Beta-glucan is a specific kind of fiber that can dissolve in water. It’s composed of glucose molecules linked together in a specific arrangement. When consumed, beta-glucan forms a gel-like substance in the gut, which helps with digestion and nutrient absorption.
What is the Best Source of Beta-Glucan?
The primary source of Oat beta-glucan is oat bran, the outer layer of the oat grain. Oat beta-glucan is typically extracted from this part of the oat kernel for use in supplements and functional foods. This makes oat beta-glucan both a natural and readily available ingredient.

How Much Beta-Glucan in 100g Oats?
100g of oats contain approximately 3-8 grams of beta-glucan, depending on the type of oat and processing method; with most stating around 5 grams per 100g as a typical amount.
Oat β-Glucan Manufacturing Process
As a pet food ingredients supplier greenagribio produces oat beta-glucan involves several steps to ensure its purity and potency:
- Harvesting and Cleaning: Harvest and clean oats to remove dirt, debris, and other contaminants. They separate the oat kernels from their husks.
- Extraction: Clean and prepare the oat kernels to extract the beta-glucan. They typically use water-based extraction methods to isolate the soluble fiber from the other components of the oat.
- Purifiction: Once extracted, the beta-glucan undergoes a series of purification steps to remove any residual starches, proteins, or impurities that might interfere with its effectiveness.
- Drying and Powdering: After purification, dry and grind the beta-glucan into a fine powder, which makes it easier to mix into pet food or formulate into supplements. Some manufacturers may also produce a liquid form for easier administration.
- Quality Control: At each step of the process, implement strict quality control measures to ensure that the final product is free from contaminants like heavy metals, pesticides, and other toxins. We also conduct testing to verify the concentration of beta-glucan and its bioavailability.
Greenagribio supply Oat beta-glucan powder is perfect for vegetarians or dogs on low protein diets. No Preservatives, additives, fillers, flavors, or colors.
Dry Food vs. Wet Food Ratio
When incorporating oat beta-glucan into a pet diet, it’s important to consider the type of food your pet eats. Both dry and wet food can be effective carriers of beta-glucan, but each has its pros and cons.
- Dry Food: Dry kibble is often used for its dental health benefits, as it helps scrape tartar from your pet’s teeth. It also typically has a longer shelf life and may be more economical. When using dry food, beta-glucan can be incorporated into the kibble either during manufacturing or as a supplement sprinkled on top.
- Wet Food: Wet food is often more palatable for pets and can be beneficial for those with dental issues, as it’s easier to chew. However, wet food is more prone to spoilage and has a shorter shelf life. Beta-glucan in wet food can be added directly, providing an easier means of administration for picky eaters.
A balanced diet that combines both dry and wet food is ideal for many pets. A general recommendation for a mixed diet is around 70% dry food to 30% wet food, although this ratio can be adjusted depending on the pet’s dietary needs, activity level, and health conditions.

Beta Glucan for Pets Dosage
Pet owner usually determine the amount of beta glucan powder bulk based on the pet’s (dog, cat, etc.) weight, age, activity level, and overall diet structure. Here are some general reference standards:
1. Small Dogs (under 20 lbs)
- Dosage: 50–100 mg per day
- Forms: Typically available in powder or capsule form. For dogs in this weight range, a powdered form can be sprinkled on food for easy administration.
2. Medium Dogs (20–50 lbs)
- Dosage: 100–200 mg per day
- Forms: As above, powder or capsules can be mixed into food. Some pet owners may prefer to break open capsules and sprinkle the powder on wet food.
3. Large Dogs (50–100 lbs)
- Dosage: 200–400 mg per day
- Forms: A higher dosage is appropriate for larger dogs, and again, powder or capsule forms work well. Larger dogs may also benefit from specialized formulations with higher concentrations of beta-glucan.
4. Extra-Large Dogs (over 100 lbs)
- Dosage: 400–600 mg per day
- Forms: In this category, dogs may need higher doses, and it’s best to choose products designed specifically for larger animals or consult with a vet for exact recommendations.
5. Cats
- Dosage: 50–100 mg per day
- Forms: Similar to dogs, powder or capsule form works well for cats, but they can also take it with wet food or directly in a small treat if they’re picky eaters.
