Frequently Asked Questions
Can supplements alone fix my gut health?
No — supplements can support digestion, microbiome balance and gut barrier function, but lasting improvement usually requires diet changes (more fiber, less processed food), stress management, sleep and sometimes medical evaluation. Use supplements as part of a broader plan.
Which ingredients should I prioritize for bloating and irregular stools?
Prioritize prebiotic fibers, digestive enzymes and low-FODMAP-friendly greens. Prebiotics feed beneficial bacteria, while enzymes help break down food and reduce gas. Start with low doses to assess tolerance.
Are mushrooms and greens safe if I have a sensitive stomach?
Many people tolerate greens and mushroom extracts well, but some experience nausea or stomach upset. Start with half servings and take with food. If you have a history of GI disorders, check with your clinician before starting new supplements.
