What It Is

Cooper Complete®  Microbiome Fiber supplement is a daily prebiotic microbiome fiber supplement with 6 grams of tasteless and gritless soluble fiber, low FODMAP for regularity and gastrointestinal health.†

How to Use:

As a dietary supplement, adults take one (1) scoop daily or as directed by their health care professional. Dissolve powder in a beverage of your choice or add to food. Each canister contains 30 servings.

How It Helps

Microbiome Fiber is a prebiotic soluble fiber supplement that is low FODMAP and contains 6 grams of soluble fiber per serving. (FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols, fermentable short-chain carbohydrates challenging to digest.) This prebiotic soluble fiber supplement is grit-free, taste-free, uncolored, and unflavored, and it dissolves clearly and quickly into food or water. It is not temperature-sensitive and may be used in both cold or hot drinks. As non-digestible fibers, prebiotics fuels beneficial gut bacteria, helping maintain a healthy balance crucial for digestion and overall well-being.

Higher fiber intake is associated with a lower risk of many major diseases.

Bowel Health

Microbiome Fiber supports digestive health by fostering beneficial bacteria growth and maintaining a balanced microbiome. This helps alleviate bloating, gas, and constipation, supporting bowel movement regularity and stool consistency. This soluble fiber is rich in prebiotics and helps comfortably and gently move food through the digestive tract without bloating or excess gas. Microbiome Fiber is safe to use by those with Irritable Bowel Syndrome (IBS).

Microbiome Fiber increases bifidobacteria and lactobacillus levels in the gut microbiota.

Glycemic Index Reduction

When taken with a meal, this prebiotic soluble fiber reduces the glycemic index of foods, which helps decrease post-meal blood sugar spikes.†

Weight Management

Guar fiber, the active ingredient in Microbiome Fiber, acts as a bulking agent in the gut, delays gastric emptying, and increases feelings of satiety. In a review of guar fiber and appetite control, regularly consuming guar fiber reduced between-meal snacking by about 20 percent.

Immune Function

Prebiotics help the body fight off sickness by keeping the gut healthy, as approximately 70 percent of the immune system resides in the gut.

This product contains NO gluten, milk/dairy, sugar, or genetically modified organisms (GMOs).

As a dietary supplement, adults take one (1) scoop daily or as directed by their health care professional. Dissolve the powder in a beverage of your choice or add it to food.

Reviews of Microbiome Fiber Supplement

  1. Nice container. Easy to store. The first use went well, but the second day it sent me on frequent bathroom trips with some discomfort. I cut back to 3 times per week. It doesn’t completely dissolve (4 Stars); a gel is left in the glass. I’ve even tried my blender. It needs to be vigorously stirred up until the time of drinking. Overall, I like it.

6 Questions
Ask a Question

How does Microbiome Fiber compare to chia seeds?


Chia is a member of the mint family and was historically used as a staple food in the ancient Aztec diet. An unprocessed whole grain, chia seeds can be digested whole or ground up and have a mild, nutty flavor. Chia seeds are also a good source of fiber, with 5 grams of fiber per tablespoon. While chia seeds also contain omega-3 fatty acids, they are in the short-chain form, which is poorly absorbed compared to the long-chain form found in marine sources.

Per tablespoon, chia seeds contain 70 calories, 4.5 grams of fat, 5 grams of fiber, and 2.5 grams of protein. Because they’re so caloric, measure them when adding them to yogurt, hot cereal, salad, or baked goods.

We like our Microbiome Fiber, a tasteless, gritless soluble fiber that’s easy to incorporate into beverages or foods (hot or cold). Its serving size is only 13 calories while providing 5.6 grams of fiber. While a tablespoon of chia seeds contains 2.5 grams of protein, it also contains 4.5 grams of fat, and the extra calories must be considered.
