InnovixLabs Broad Spectrum Prebiotic Fiber
A prebiotic built on the argument that different gut bacteria ferment different fibres, so a spectrum of fifteen plant-based fibres feeds more of the microbiome than any single source can. It is third-party tested and guaranteed gluten-free, at $24.99. The principle is sound and reasonably well supported; what the page does not give is the total gram amount or the individual fibres.

What’s in it
Amounts are shown only where the manufacturer publishes them. Anything without a figure is undisclosed — and for an active ingredient, an undisclosed dose is the central problem with this category.

How the manufacturer says it works
InnovixLabs describes it as the first prebiotic with over fifteen plant-based prebiotic fibres to nourish healthy gut flora, presents it as suited to keto and low-carbohydrate diets, and states it is third-party tested and guaranteed gluten-free.
What the evidence actually supports
Fibre diversity is a defensible principle rather than marketing invention: different bacterial species ferment different substrates, and dietary fibre diversity correlates with microbiome diversity in observational work. A spectrum product is a reasonable way to act on that. Third-party testing and a gluten-free guarantee are both stated, and at $24.99 it is competitively priced against single-fibre products.
Where that evidence stops
The total gram amount is not published, which for a fibre product is the number that determines whether it does anything — fifteen fibres at a fraction of a gram each is a different product from fifteen fibres totalling five grams, and the page does not distinguish them. The individual fibres are not named either, so tolerance cannot be predicted: some plant fibres are high-FODMAP and poorly tolerated in IBS while others are not. Diversity has not been shown to outperform a well-dosed single fibre in controlled comparison. Effects on your own GLP-1 secretion through fermentation are modest and nothing like a medication.
Strengths and problems
Strengths

- The individual fibres are not named, so tolerance cannot be anticipated
- Diversity has not been shown to beat a well-dosed single fibre in trials
- Directions, warnings and refund terms were not published on the page we captured

May suit
Someone who wants broad microbiome coverage rather than a single fibre, and will check the total grams per serving on the physical label first.
Do not use if
- You have IBS and cannot see which fibres are included
- You need a specific gram target for constipation
- You have a bowel stricture or history of obstruction
Frequently asked
Is fibre variety better than one good fibre?
Plausibly, but it is not settled. Different bacteria ferment different substrates, and people eating a wider range of plant fibres tend to have more diverse microbiomes — which is where the idea comes from. What has not been shown is that a fifteen-fibre supplement beats an adequate dose of a single well-studied fibre like psyllium or acacia in a head-to-head trial. Dose is the more reliable lever, which makes the missing gram figure the important gap here.
