Wörwag Pharma GmbH & Co. KG has expanded its product range with the innovative dietary fiber supplement ReDia®. With a patented formula, the fiber complex helps reduce the rise in blood sugar levels after meals.
New at Wörwag Pharma: ReDia

Dietary fibers are an important part of a healthy diet. These indigestible food components have a variety of positive effects on health. Among other benefits, they can help reduce the rise in blood sugar levels after meals. This effect depends on the specific properties of the fiber.
Patented Formula for Optimized Effects
The innovative dietary supplement ReDia® contains the fiber hydroxypropyl methylcellulose (HPMC), which is derived from plant-based cellulose. Thanks to a patented formula, it delivers optimized effects on blood sugar levels.*
Fruity Drink Before Meals
The fiber granules are dissolved in water before a meal and consumed as an orange-flavored drink. In the stomach, the fiber complex mixes with the food and forms a gel-like consistency, which slows the absorption of sugar into the bloodstream. This way, the HPMC in ReDia® helps reduce the post-meal spike in blood sugar levels.
Flattening Blood Sugar Curves
Easily digestible carbohydrates—such as those found in sugar, white flour, pizza, and pasta—can cause sharp spikes in blood sugar, followed by a counter-regulatory response from the blood sugar-lowering hormone insulin. Noticeable effects of these rapid blood sugar fluctuations can include the well-known “afternoon slump” or cravings. Over time, pronounced fluctuations in blood sugar and their metabolic consequences can strain the body. A high fiber intake as part of a wholesome, healthy diet, combined with regular physical activity, can help reduce blood sugar spikes and support overall health and well-being.
Special Gel-Forming Properties
The HPMC fiber in ReDia® has special swelling and gel-forming properties due to its patented formula. This enhances its effects on blood sugar levels. As studies show, the gel-forming properties of a fiber influence its ability to lower blood sugar after meals (1,2).
ReDia® is vegan and free from gluten, sugar, and lactose.
One package contains 30 sachets, each with 4 g of HPMC. It is recommended to take one sachet per day as a drink before a main meal. ReDia® is now available in pharmacies.
