Frequently Asked Questions

What is Glucosalive™ glucosamine made from?

Glucosalive™ is a vegan, vegetarian and shellfish free glucosamine. Non-GM bacteria act upon a plant based fermentation medium to produce glucosamine. Great care is taken in the processing and packaging of Glucosalive™ to ensure the highest quality glucosamine sulfate material is available.

What is normal glucosamine made from?

Most glucosamine on the market is sourced from shellfish, such as shrimp, crabs, oysters and lobster. Shellfish play a number of vital roles in waterway ecosystems, often involved in critical nutrient recycling. This makes them an important part of the environmental balance, and they need to be protected from overfishing.

Does it work the same as normal “glucosamine”?

Glucosalive™ is indeed a glucosamine sulfate; the primary difference being the way in which it’s made – extracted from bio-fermented plant materials using a unique patented process; free from GM bacteria and industrial by products. It is the same chemical structure as “normal” glucosamine.

How does Glucosamine help to support joint health?

Every year, thousands of Australians use glucosamine to support their joint health. There are a number of proposed mechanisms by which glucosamine may help to support joint health; mainly involved in the activity of chondrocytes. 

  Chondrocytes are the cells responsible for the production and maintenance of the extracellular matrix of cartilage.
  • Glucosamine is a component of proteoglycans; the structural compound that give cartilage its elastic property when under load such as when you walk.
  Glucosamine may directly inhibit inflammation; in particular it may positively influence those inflammatory pathways that adversely affect the activity of chondrocytes.
  Glucosamine may indirectly inhibit inflammation by altering the bacterial balance in the gastrointestinal tract.
  Glucosamine in the sulfate form may contribute to the amount of sulfur available for the synthesis of proteoglycans and other intermediaries necessary for chondrocyte metabolism.


Does Glucosalive™ affect blood sugar levels?

In the late 1990’s, a discussion of animal data published in the Lancet raised concerns about the effect of glucosamine on blood sugar levels. However, a 2005 review examining clinical trial data from human studies involving 3063 human subjects did not agree with this finding. Instead, the review found that there was no evidence that glucosamine supplementation had an impact on normal glucose metabolism.

Can I take Glucosalive™ if I have shellfish allergies?

Unlike the most common forms of glucosamine available, Glucosalive™ is sourced from plants. This makes it suitable for those with shellfish allergies.

  • Is Glucosalive™ suitable for Halal or Kosher diets?

Yes, Glucosalive™ is Halal and Kosher friendly.

Is it true that Glucosalive™ is generally much lower in pollution than shellfish sourced glucosamine?

It is an unfortunate fact of life that the pollution of waterways is on the increase. Heavy metal and chemical contamination from industrial, agricultural and mining activities is a widespread problem throughout a number of environmental niches. Dietary intake of environmentally polluted foods and their derivatives is considered to be the main route of exposure to many of these toxins.

Given this, it is important for consumers to manage their exposure to food sources of contamination. In one study, shellfish were shown to have the highest levels of cadmium and arsenic among a number of tested seafoods.

Heavy metal testing of Glucosalive™ has shown that the material contains less arsenic than other glucosamine products that it has been tested against.

Glucosamine from Shellfish

Glucosamine from Fungi




Citric Acid production waste

Bio-fermentation of plant based medium





Heavy Metal Risk

Water pollution may affect shellfish

Low risk

Low risk

The finished product undergoes a wide panel of tests for heavy metals, covering Arsenic, Lead, Cadmium, Mercury, Iron and total Heavy Metals

Chemical Residue Risk

High risk - dependent upon water quality

High risk – Citric acid residue can be detected at dozens of ppm level in the fungal sourced glucosamine

Low risk


I have another fermented/vegetarian glucosamine. What is the difference?

There are other fermented glucosamine products available, it’s true. Some of these products are produced using genetically modified organisms. Other products are the result of the fermentation of industrial by products. This can result in residual starting material in the finished product.

Glucosalive™ uses a plant based starting medium that is subject to a specialized and patented process utilizing GM FREE bacteria to create a pure, vegan friendly glucosamine.
