What is Dona®?
Dona® contains crystalline glucosamine sulfate, a naturally occuring substace found in cartilage to cushion joints. Dona® helps in maintaining cartilage health so that you can actively participate in daily activities such as walking, climbing stairs, etc.
Dona® has been proven effective and safe in major clinical trials. It may promote cartilage health, lubricate joints, and support joint mobility and flexibility. Dona® can be taken with water or juice, with or without food and even in the morning or at night.
The Original Glucosamine
Dona® is the original Crystalline Glucosamine Sulfate that has been shown effective in two 3-year controlled clinical studies. Dona® helps maintain the normal function of cartilage and supports healthy joint function, mobility, and flexibility. Healthy cartilage allows you to keep doing the activities you love, such as walking, climbing stairs, swimming, running, and even the simple joy of picking up your child or grandchild. It is supported by product-specific clinical data and has been evaluated in over 7,000 patients with joint discomfort in over 25 clinical trials.
Dona® is not your everyday Glucosamine Sulfate. It is different than what you may find in stores or online today. Dona® contains a specific type of glucosamine sulfate developed and sold in more than 60 countries around the world. Dona® is a stable form of glucosamine which is able to reach the joints in the right concentration. Dona® is also the only glucosamine endorsed by the Cochrane Review 2009 and is recommended by the ESCEO algorithm for joint health management.
Crystalline Glucosamine Sulfate is a formulation invented and patented by RottaPharm. It presents a method to stabilize glucosamine sulfate, through a chemical process of co-precipitation with sodium chloride, thus obtaining Crystalline Glucosamine Sulfate.
- Sold in over 60 Countries as a Prescription
- Over-the-counter in the USA
- Millions sold around the world
- Recommended by healthcare providers
- Evaluated in over 7,000 patients with joint discomfort in over 25 clinical trials
How Crystalline Glucosamine Sulfate Works
The crystalline glucosamine sulfate in Dona® may act by preventing the breakdown of muscles and cartilage around joints. It may also influence the body's response to joint discomfort, thereby decreasing joint tenderness and soreness. Crystalline glucosamine sulfate may also be known to prevent an inflammatory reaction in the joint that can be caused by aging or damage, thereby keeping your cartilage healthy. Healthy cartilage is necessary to keep your joints flexible and free from any discomfort.
While the exact mechanism by which crystalline glucosamine works is continuously being explored, it has been proposed to work in one of two ways.
-
Crystalline Glucosamine Sulfate provides a base for the production of glycosaminoglycans and proteoglycans (including chondroitin sulfate and hyaluronic acid), which are the building blocks of cartilage.
-
Glucosamine has been thought to stimulate the synthesis of glycosaminoglycans, proteoglycans, and collagen.
The two most common forms of glucosamine are glucosamine hydrochloride and glucosamine sulfate. Of the two, glucosamine sulfate - specifically crystalline glucosamine sulfate, has been evaluated for its effect on cartilage health; the effect of the hydrochloride form on cartilage still needs further conclusive evidence.
