We've got straight answers.

FLOW is your daily probiotic — 40 Billion CFU to build and maintain a healthy gut microbiome over time. CORE is a digestive enzyme supplement designed to help your body break down what you eat at every meal. MELT is an oral strip that combines probiotics and enzymes in one — it dissolves on your tongue in seconds, no water needed. If you want comprehensive gut support, FLOW + CORE cover your daily base, and MELT is perfect for on the go.

Yes — our products are designed to complement each other. FLOW and RESET work well together in the morning. CORE is best taken before meals. MELT and SPARK can be used anytime. If you're new to gut health supplements, start with one product for 2–3 weeks before adding more, so you can tell what's working.

Probiotics take time to establish in your gut — allow 3–4 weeks of consistent daily use for meaningful microbiome changes. Digestive enzymes like CORE tend to work faster, as they support digestion at the meal level. Results vary depending on your diet, lifestyle, and starting gut health. Consistency matters more than anything else.

Yes. All ROVAHA products are vegan-friendly. Our capsules use hypromellose (vegetable capsule) instead of gelatin, and our strips use pullulan — a plant-based film. All formulas are free from animal-derived ingredients.

MAKTREK® is a patented delivery system used in ROVAHA FLOW. It uses a complex of marine polysaccharides to protect probiotic bacteria from stomach acid, allowing them to reach the intestine alive and active. Standard probiotics can lose up to 80% of their potency before reaching the gut — MAKTREK® is designed to significantly reduce that loss.

All ROVAHA products are gluten-free, lactose-free, and allergen-free. They contain no wheat, dairy, soy, eggs, nuts, or shellfish. If you have a specific allergy concern, check the full ingredient list on each product page or contact us at support@rovaha.com.

Our products are manufactured in FDA-registered, GMP-certified facilities in the USA. GMP certification requires independent auditing of manufacturing processes, quality controls, and ingredient verification. If you'd like specific documentation, email us at support@rovaha.com and we'll send it over.

FLOW is best taken split across the day — one capsule in the morning, one in the evening. Taking probiotics consistently at the same time each day helps maintain stable levels in your gut. They can be taken with or without food.

No — that's the whole point. MELT and SPARK strips dissolve directly on your tongue in seconds. No water, no capsules, no prep. Place a strip on your tongue and let it dissolve. One strip per day, anytime.
