Digestive balance

Supports regular bowel movement, reduces heaviness and bloating. Better nutrient absorption helps your body truly benefit from what you eat.

Immune support

Strengthens the body’s natural defense and helps reduce inflammation. Greater resilience during seasonal challenges.

Daily energy

More stable blood sugar levels, less sugar cravings and steady energy throughout the day — without short-term “boost” effects.

📦 Powder Form

RTS fiber products come in powder form. For precise dosing, using kitchen scales is recommended.

🌾 Start with the Base

We recommend starting with RTS Fiber W , which helps support digestive balance and prepares the body for other complexes.

⏰ How to Use

Take in the morning 30–40 minutes before breakfast.
Start with 5 g daily, increase to 10 g after 2 days.
Mix with a glass (200 ml) of water.

💧 Important

Drink enough water throughout the day while using fiber. Regular fiber intake is part of a balanced diet.
