Frequently Asked Questions

Most gut products only address one part of digestive health. The Gut Health Stack covers all three layers: a probiotic for flora balance, prebiotic fiber for regularity, and botanicals for gut lining support. This synergy delivers more complete and lasting benefits than any single supplement on its own.*

It’s ideal for anyone who experiences occasional bloating, irregularity, or digestive discomfort, or wants to maintain a strong gut-immune connection. It’s also a smart choice for post-antibiotic support or when resetting gut health.*

  • Bacillus Coagulans: Take 1 capsule daily with a meal for optimal absorption.*
  • FiberMend®: Mix 1 scoop into water, juice, or a smoothie once daily. It dissolves easily and is well tolerated, even for sensitive digestion.*
  • EnteroMend®: Take 2 capsules, one to two times daily with food, or as recommended by your healthcare provider.*

Yes. Each product is designed for daily use and can be safely integrated into your routine. Consistent use provides the best results for gut balance and resilience.*

Some people feel improvements in digestion and regularity within the first 1–2 weeks. For others, benefits build gradually over several weeks as the microbiome and gut lining strengthen.*

Yes, the Gut Health Stack pairs well with most supplement routines. If you are on prescription medications or have a medical condition, check with your healthcare provider before starting.

Most gut supplements only tackle one piece of digestive health. The Gut Health Stack was built to cover it all — a probiotic to balance flora, a prebiotic fiber to support regularity, and botanicals to calm the gut and protect the lining. Together, these three products work synergistically to improve digestion, reduce discomfort, and build long-term gut resilience — benefits you won’t get from taking a single supplement alone.*

Allergy Warning: This stack is contraindicated in individuals with a history of hypersensitivity to any of its ingredients.

Pregnancy: If pregnant, consult your health-care practitioner before using these products.

Interactions:

  • Bacillus Coagulans and FiberMend® have no known adverse interactions or contraindications at the time of publication.
  • EnteroMend® contains curcumin, which has been shown in animal and in vitro studies to interfere with certain chemotherapy drugs (including cyclophosphamide and irinotecan). Concurrent use with these agents should be avoided.

Other Warnings:

Do not remove Bacillus Coagulans powder from its capsule, as the capsule is required for proper delivery.
