More about Pharmaceutical-grade Xylitol


Pharmaceutical grade xylitol is the purest form of xylitol available, and is the xylitol used in all Xlear and Spry products. It is sourced from sustainably-farmed, non-GMO corn cobs and stalks. This source is far easier to break down into pulp for processing, whereas Birch wood chips and bark require strong acids to accomplish the same thing. Unless Genetically Engineered (as they refer to it), the trees can take up to 20 years to reach maturity, whereas corn is an annually renewable crop. The food production is unaffected, as only the cobs and stalks are utilised. Every batch of Xylosweet is tested in the U.S.A. for conformity to pharmaceutical-grade specifications.

Xylitol is the sweetest of all bulk sugar substitutes. Currently used in many sugar-free products, it is increasingly gaining acceptance as an alternative sweetener, and using it actually helps reduce the development of dental cavities.

Unlike artificial sweeteners, Xylosweet is derived from totally natural sources, and is even produced by the human body during normal metabolism!

Xylosweet is no longer imported for distribution in South Africa, because it costs a lot more than the house-brand food-grade xylitol available from discount food stores and other retailers.

  • Made from naturally-occurring xylan fibre in corn cobs – also found in plums, strawberries and other fibrous fruits and vegetables
  • Interchangeable with sugar for most cooking applications.
  • Approved by both the World Health Organization and the FDA as safe in unlimited quantities as a food additive.
  • Has a chemical structure different from that of table sugar, which helps to promote oral and dental health.
  • In some cases, initial consumption of more than 80g. per day may have a laxative or bloating effect until the body becomes accustomed to the sweetener in larger quantities.


What Is Xylitol:

Pure Xylitol is a white crystalline substance that looks and tastes just like sugar. It occurs naturally in many fibrous fruits and vegetables and is produced by the human liver each day as part of our normal metabolism. It is the sweetest of all the polyols (sorbitol, maltitol, erythritol etc.) having the same sweetness as cane sugar but without the negative tooth decay or insulin release effects. Xylitol is also slightly alkaline, so if you put some onto your tongue to dissolve, it will produce a slight tingling sensation.

A Natural Carbohydrate:

Classified on labels as a carbohydrate, Xylitol has been used in foods since the 1960’s and is approved in the U.S. as a food additive in unlimited quantity for foods with special dietary purposes. Xylitol has 40% fewer calories, and an extremely low Glycaemic Index of 7. Because it has little effect on blood sugar levels, it is safe for use by those with diabetes or hypoglycaemia.

Clinically Tested for oral health:

Almost 50 years of clinical testing confirms that Xylitol is the best sweetener for dental health. It has been shown that Xylitol helps reduce cavities up to 80% by reducing plaque. It also forms loose bonds with calcium and phosphates, and helps ”heal” acid-affected teeth by making these minerals available for the re-mineralising and strengthening of the damaged enamel. It is a safer natural alternative to Fluoride.

Xylitol For The Ear, Nose & Throat:

When certain harmful bacteria enter the body, they attach to the membranes of the nose and throat. They begin to culture and grow, causing infection and sickness. Xylitol is one of bacteria’s natural enemies. When exposed to Xylitol, harmful bacteria like Strep. pneumo and Haemophilus flu lose their ability to adhere to infected membranes and are not able to grow. Unlike most antibiotics, which kill the majority of bacteria and leave the resistant “super bacteria” behind, Xylitol merely flushes harmful bacteria away. This obviously lessens the occurrence of Inner Ear and Sinus Infections.

Widely Endorsed By Professionals:

The anti-bacterial action of xylitol has been confirmed in numerous field studies and in-vitro tests conducted throughout the world. It reduces the acid secretion of plaque (dental bacterial biofilm). This research has led to dental associations in Finland, Norway, Sweden, England, Ireland, Estonia and the Netherlands officially endorsing products containing high levels of xylitol.

Xylitol is recommended by Dentists, Medical Doctors, Periodontists, Paediatricians and many health organisations and health-care professionals worldwide.

Xylitol can be dangerous to dogs:

It’s very important to remember that our pets have a very different digestive system to that of humans. For instance, we love chocolates, Macadamia nuts, broccoli, garlic, onions, avocado pears, grapes, raisins and xylitol. The sad reality is that all of these foods are perfectly safe for humans, but can cause serious discomfort and possibly even death for our wonderful four-legged friends. Please make sure that you feed your canine pets only dog food, or other food recommended by your vet. For further information, please refer to the following:
