Glucosamine - very popular worldwide

Glucosamine has been one of the most popular supplements for decades. It is a substance which is produced naturally in the human body and is used to build and maintain joint cartilage. Millions of people worldwide choose to replenish this substance by means of a supplement.

Many different dosages and forms are available. provides a dietary supplement containing 1500 mg of glucosamine sulphate per day, the dosage and form which are applied in most of the scientific studies. The supplement also contains vitamin C, which contributes to normal collagen formation and hence to normal cartilage function. 

Approximately two out of three people say that they are (very) satisfied with the use of this supplement. The effect can usually be noticed within one to two months, but sometimes it is possible to notice the effect after shorter periods such as a week or longer periods of up to six months. This can vary from one individual to the next.  

The effect is maintained as long as the intake of glucosamine is continued. There is no problem with that. Glucosamine is a safe dietary supplement, also for long-term use. With us, such long-term use is moreover very affordable: just under £6 / €7 / $7.50 per month. And for that you get the brand product GlucosaGreen, extracted from vegetal sources.


Proper dosage guaranteed

Dietary supplements with glucosamine are often administered in too low a dosage. It regularly occurs that a supplement contains only 500 mg, 600 mg, 1000 mg, or 1200 mg of glucosamine per daily dosage, while the proper dosage is 1500 mg. This is the dosage which is used in almost every successful scientific study.

As a consequence of this low dosage the supplements do not always have the desired effect. This results in user disappointment. 

One of the reasons for the low dosage is ignorance. Unfortunately, in the world of supplements, there are active parties that are not familiar with the properties of a product like glucosamine. Another cause is legal regulation influenced by industrial lobbies, which force dosages to be reduced. This happens in Italy and Germany, for instance. 

Other causes are cost savings, not using enough capsules, or legal restrictions applicable in some countries, among others.


Quality of glucosamine

By choosing our glucosamine powder, you are choosing quality. We can guarantee it in the following way: 

Proper, high dosage. In scientific studies, 1500 mg of glucosamine sulphate has been shown to be the optimal daily dosage. Glucosamine sulphate is regularly administered in too low a dosage, unfortunately. There are many products available on the market with dosages between 500 and 1200 mg. We deliver the proper, high dosage of 1500 mg. 

Proper form. There are different forms of glucosamine. The most used are glucosamine sulphate and glucosamine hydrochloride. Successful scientific research is primarily carried out with the sulphate. We only use this form. And it has a very high degree of purity - more than 99%.

Vegetal. For this glucosamine powder product we use the GlucosaGreen brand. It  is 100% vegetal, so ideal for vegetarians and vegans. The glucosamine is extracted from glucose, derived from corn that is guaranteed non-GMO.

Safe product. The producer fulfills GMP and HACCP requirements. This means that it follows strict procedures which ensure food safety and hygiene. 

Independently tested. The end product is randomly tested for heavy metals and biological pollutants by the independent laboratory NutriControl. Click on the microscope symbol below for the most recent test results.

Combinations with glucosamine

Glucosamine is a potent dietary supplement and effective enough for many people. Still, it is possible to enhance its effect by combining glucosamine with other supplements.


The best-known combination is that of glucosamine and chondroitin. These two supplements complement each other perfectly. Many brands sell glucosamine and chondroitin as a combination product, although the dosage of chondroitin is usually low. We have chosen to provide glucosamine and chondroitin as separate products in high dosages. You can thus decide for yourself if you want to take one or both supplements. 


Arthro-5 is our most popular product. It contains six ingredients, one of which is glucosamine. The dosage of glucosamine is the same as in our separate glucosamine product. In addition, it contains chondroitin, also in the same dosage as the separate product, MSM, ASU and hyaluronic acid. We do not know a more potent product than Arthro-5 in the whole world. 

ASU Forte 

ASU Forte is a vegetarian alternative to glucosamine. There are people who benefit more from glucosamine, but it sometimes occurs the other way around as well. It is also possible to take both supplements together.



Glucosamine can have an influence on the action of certain blood thinners (vitamin K antagonists). Do not take this supplement in combination with this type of medication without consulting a doctor. Other blood thinners such as aspirin do not pose a problem.

Do not take during antibiotic treatment. 

Do not take if you suffer from glaucoma (increased eye pressure). 

Do not take during pregnancy or the breastfeeding period. 

Diabetics must check their blood sugar level during the first weeks of use.

Safe use

Glucosamine can be taken safely for a long time. It does not have any serious side effects, in contrast to many painkillers. There is no problem even if it is taken for years. 

Scientific research into long-term use (3 years) of glucosamine has not identified any serious side effects. There are no indications that even longer use would not be safe. Glucosamine has been available as a dietary supplement for over 30 years. During this period, no serious side effects have ever been reported. 

Some precautions must be taken in certain conditions and if taking certain medicines. You will find more information below.
