Strength: Tolerability and diversity
While probiotic diversity is often top of mind, prebiotic fiber diversity is often overlooked. That’s a missed opportunity, Taylor Davis, marketing manager at ingredient supplier Comet Bio, said.
“People often think, ‘Fiber is fiber.’ But if you’re only feeding your gut one type of prebiotic, only a few strains of bacteria are benefitting,” she maintained. “That’s why diversification is so important.”
Comet Bio’s arabinoxylan-based prebiotic, Arrabina, offers a naturally diverse nutrient profile that includes beta-glucan and polyphenols. That variety feeds a broader range of beneficial gut bacteria.
Crucially, it’s also shown to be gentle on the stomach. “We tested up to 15 grams and saw no difference from placebo in gas or bloating,” Davis reported. “The effective dose is just 3.6 grams. That gives people a buffer, even if they eat multiple products in a day.”
