FAQs

What does it do?

Gut Complex supports digestive balance, gut lining integrity, and immune function with a targeted blend of prebiotics, probiotics, L-glutamine, and herbal extracts. It helps soothe the gut, promote microbial diversity, and restore healthy digestion.*

Who is it for?

This is for anyone experiencing bloating, irregularity, or gut discomfort. It is especially helpful if you're recovering from antibiotics, managing food sensitivities, or looking to support long-term gut and immune health from the inside out.*

How soon will I feel a difference?

Many customers notice improved digestive ease and reduced bloating within the first week. By weeks 2 to 4, digestion, gut regularity, and microbial balance often improve. With daily use, long-term benefits like immune support and gut wall integrity continue to build over time.*

Is it safe to take every day long-term?

Yes, our Gut Complex is formulated for daily use using gentle botanicals, amino acids, and probiotics. It’s designed to help support gut barrier integrity and overall digestive health. As always, consult your provider if you have chronic GI conditions or are taking medications.*

What if I’m pregnant, nursing, or on medication?

Please consult your healthcare provider before using if you are pregnant, nursing, taking medication, or have a medical condition.*

Week 1

You may notice improved digestive ease and less bloating as the soothing blend begins supporting gut lining integrity and overall comfort.

Week 2–4

Gut regularity, digestion, and intestinal comfort often improve as the gut barrier strengthens and microbial balance begins to stabilize.

Month 2+

With continued use, Gut Complex supports long-term digestive resilience, enhanced immune function, and the integrity of the gut wall, laying the foundation for whole-body balance.

Build on progress

The perfect pairings

Consider pairing Gut Complex with GI Cleanse or Prebiotic Fiber to reset digestion and nourish the gut, or Probiotic 100 Billion for microbiome resilience and deeper digestive clarity.*

Supporting acts

Beyond supplements

It’s called a supplement for a reason. The Gut Complex is just one part of your daily ritual for digestive comfort, gut lining support, and microbiome health. It’s here to add to what truly matters — what you eat, how you move, and the intentional choices you make each day.

  • Eat gut-friendly foods

    Include fiber-rich, anti-inflammatory foods like oats, sweet potatoes, fermented vegetables, bananas, ginger, and cooked greens. These work with your supplement to support microbiome diversity, regularity, and bloat reduction.

  • Move to aid digestion

    Gentle movement like walking, yoga, or abdominal stretching helps reduce bloating, support motility, and activate your parasympathetic nervous system. These practices allow your gut to function more efficiently.

  • Lower daily stress

    Stress directly impacts gut health by disrupting digestion and microbial balance. Daily calming practices like breathwork, journaling, or simply slowing down support the gut-brain connection and help your supplement work more effectively.
