Core Fiber is for those looking for more than “just staying regular.” It’s fiber for doers. Those who are active, busy, and want more out of life.

More Fiber, More Support:
Each serving delivers 6g of fiber—more than most powders or gummies—so you get real digestive support you can feel.

Soluble & Insoluble Fiber:
Core Fiber includes both types of fiber your body needs. Soluble fiber feeds your gut microbes and supports smoother digestion. Insoluble fiber helps keep everything moving—naturally and effectively.

Built for Real Life:
Whether you’re lifting, working, parenting, or all of the above, Core Fiber fits right in. It supports digestion, nutrient absorption, and all-day energy—so you can feel lighter, stronger, and more balanced.

Clean, Easy, Effective:
No artificial flavors. No fillers. Just a gut-friendly blend that mixes fast, tastes great, and actually works.

Core Fiber contains:
