If you follow a gluten-free diet, getting enough fiber can be a challenge. Many high-fiber foods (like whole wheat, barley, and rye) contain gluten, leaving those with celiac disease or gluten sensitivity struggling to meet their daily fiber needs.
That’s where gluten-free fiber supplements come in. But with so many options—psyllium husk, acacia fiber, chia seeds—how do you choose the right one?
This guide covers:
✔ Why fiber matters on a gluten-free diet
✔ The best gluten-free fiber supplements
✔ How to pick the right one for your needs
✔ Answers to common questions
Let’s dive in and keep your digestion running smoothly—without the gluten!
Why Fiber Matters (Especially on a Gluten-Free Diet)
Fiber is essential for:
✅ Digestive health (prevents constipation)
✅ Gut microbiome balance (feeds good bacteria)
✅ Blood sugar control (slows glucose absorption)
✅ Weight management (keeps you full longer)
The problem? Many gluten-free diets are low in fiber because they avoid whole grains. That’s why supplements can help fill the gap.
