Frequently Asked Questions

Why does fiber make me bloated?

Many fiber supplements ferment too quickly in one area of the gut, which can create excess gas and digestive discomfort. Phase Fiber™ was designed differently with Triple-Phase Fermentation — a system of three prebiotic fibers that work Fast, Steady & Slow throughout the digestive tract.* This helps support more comfortable digestion and complete gut coverage without the intense bloating commonly associated with traditional fiber supplements.*

What is Triple-Phase Fermentation?

Triple-Phase Fermentation is the clinically designed system behind Phase Fiber™. Instead of using a single fiber source, Phase Fiber combines three premium branded prebiotics that ferment at different times throughout the digestive tract: Fast (0–12hr), Steady (12–24hr), and Slow (24–48hr).* This helps support the entire gut microbiome while promoting digestive comfort and regularity.*

What makes Phase Fiber different from other fiber supplements?

Most traditional fiber supplements use a single fiber ingredient that ferments rapidly in one area of the gut. Phase Fiber™ uses three clinically studied prebiotic fibers — Fibalance™ PHGG, PreticX™ XOS, and Solnul® RS2 — designed to deliver more complete microbiome support throughout the digestive tract.* The formula is also made with Low-FODMAP certified ingredients and dissolves easily without grit or heaviness.*

Is Phase Fiber good for sensitive stomachs?

Yes. Phase Fiber™ was formulated with sensitive digestion in mind. Two key ingredients are Low-FODMAP certified, and the Triple-Phase Fermentation approach helps avoid the rapid fermentation that can cause discomfort with many fiber products.* The flavorless powder is gentle, easy to mix, and designed for comfortable daily use.*

How do I take Phase Fiber?

Mix one scoop daily into 8–12 oz of water, coffee, smoothies, or your favorite beverage. Phase Fiber™ dissolves easily without changing the taste or texture. If you’re new to fiber supplements, you may prefer starting with half a scoop for the first few days before increasing to a full serving.*

Can I take Phase Fiber with probiotics?

Absolutely. Prebiotics and probiotics work together synergistically. While probiotics help introduce beneficial bacteria, prebiotics help nourish and support them. Phase Fiber™ pairs especially well with probiotic formulas like Flora Biome™ as part of a complete gut health routine.*
