What is Glucosamine?

Glucosamine is an amino sugar synthesized within the body. Glucosamine is made up of glucose and amino acid, glutamine.

It is known to be a powerful anti-inflammatory agent, which reduces the severity of the inflammation and also alleviates various inflammatory symptoms like pain, swelling, and redness.

For these reasons it widely used as a treatment for osteoarthritis and various other joint inflammatory disorders.

A good number of scientific studies have shown that glucosamine not only helps in alleviating the symptoms of osteoarthritis but also delays the progression of the disease.

It is also said to possess strong wound healing properties along with anti-aging benefits.

Glucosamine is largely used in combination with another joint supplement, chondroitin.

Studies conducted on this combination have shown that these two can help in relieving the pain, improving the physical function and have an effect on the stiffness, which is one of the classic symptoms of osteoarthritis. [1]

Different Forms of Glucosamine

Based on the origin, glucosamine can be categorized into two types, namely, shellfish glucosamine and non-shellfish/vegetarian glucosamine.

Shellfish glucosamine is obtained by chitin processing from the shells of crustaceans like shrimps, crabs, and lobsters.

On the other hand, non-shellfish glucosamine is manufactured from corn fermentation and Aspergillus niger. Non-shellfish glucosamine serves as an alternative for vegetarians and vegans.

Based on the salt form, glucosamine can be categories into two types, which are glucosamine sulphate and glucosamine hydrochloride.

Of all these forms glucosamine sulphate is broadly used and is backed by a good number of scientific studies.

Glucosamine sulphate is stabilized by salt and this compound is of 74% purity. On the other hand, glucosamine hydrochloride is of 99% purity.

Both glucosamine sulphate and glucosamine hydrochloride are proven to be effective in alleviating the symptoms of osteoarthritis. [2]

Glucosamine: Mechanism of Action

Glucosamine’s exact mechanism of action is not known.

However, a few studies conducted in recent years have elucidated the glucosamine’s action mechanism to a certain extent.

Glucosamine acts as a component of glycosaminoglycans, which in turn is the key constituent of cartilage.

Glucosamine possesses strong anti-inflammatory properties. Glucosamine is proven to reduce the levels of inflammatory biomarkers like prostaglandin-E2, interleukin(IL)-8, etc., and biomarkers for collagen and cartilage degeneration and thereby delay the progression of inflammation, bring down the severity of the symptoms and improve the joint functions [3]

The chondroprotective action of glucosamine comes from its ability to delay the catabolic or degenerative processes that are triggered by the inflammation in the cartilage. [4]

Key Health Benefits of Glucosamine

Glucosamine is popularly known as a joint supplement due to its positive impact on the symptomatic and structure outcome of joint inflammation. It is found to alleviate the symptoms of osteoarthritis and rheumatoid arthritis. Glucosamine is also said to have an active role in reducing collagen/cartilage degeneration and soothing the inflammatory symptoms like tenderness, swelling, and pain.

1. Glucosamine Helps In Delaying The Progression Of Knee Osteoarthritis (OA)

Osteoarthritis is a joint degenerative disease caused due to the breakdown of joint cartilage.

Learn more about osteoarthritis here:

As a powerful anti-inflammatory agent, glucosamine helps in delaying the progression of osteoarthritis by reducing the cartilage degeneration.

Glucosamine works on the inflammation by reducing Interleukin-1-stimulated catabolic enzymes and inflammatory markers that are responsible for cartilage breakdown and inflammatory reactions like pain, edema, and redness. [1]

Confidence Level: High

A study conducted in 2012, has shown that glucosamine serves as a disease-modifying agent with a carryover effect.

Glucosamine was reported to improve conditions like pain, stiffness and physical functions.

It was also concluded that long term usage of glucosamine could help in reducing the dependence on NSAIDs and delaying the progression of osteoarthritis. [2]

A study conducted in 2001 on the long-term effects of glucosamine sulphate on OA progression has shown that glucosamine could effectively reduce the joint space loss in patients with low-grade osteoarthritis.

It was a 3-year randomized, double-blind placebo-controlled trial which involved 212 knee osteoarthritis patients. [3]

In a 1998 study, a daily dose of 1500mg/day glucosamine for a month was reported to have shown the same results as ibuprofen in 170 Chinese patients, only with lesser side effects. [4]

Several other studies conducted on glucosamine’s efficacy have proved that glucosamine could be a safer treatment option for osteoarthritis over NSAIDs. [5] [6] [7] [8]

2. Glucosamine Reduces The Joint Pain And Tenderness

Joint pain and tenderness are the key symptoms of inflammation. Regular usage of glucosamine has proven to help in reducing the severe pain and improve the joint function.

Confidence Level: High

A double-blind randomized clinical trial study conducted in 2012, has shown that glucosamine in combination with alendronate helps in relieving pain and stiffness and improving the joint functions in Degenerative Joint Disease at a faster rate. [9]

A three-year study that involved 202 patients has shown that 1500mg of glucosamine once daily, can reduce the pain and have a positive impact on the joint functions. [10]

Multiple studies have been conducted on glucosamine’s impact on pain, tenderness and joint functions in osteoarthritis patients and a majority of the studies have reported that glucosamine is an effective form of treatment for the above-mentioned conditions with least side effects. [11] [12] [13] [14]

3. Glucosamine Helps Relieve Temporomandibular Joint(TMJ) Osteoarthritis Symptoms

Various body parts like wrist, shoulder, ankle, and TMJ are affected by osteoarthritis. TMG osteoarthritis is said to damage the cartilage, synovial, and many surrounding tissues. Glucosamine might help the condition by reducing the pain and improving the joint function. [15]

Confidence Level: Moderate

In a randomized double-blind controlled study conducted in 2001, the efficacies of glucosamine (1500mg/day) and ibuprofen (1200mg/day) were evaluated against TMJ osteoarthritis. Both glucosamine and ibuprofen reduced the pain; however, glucosamine had a greater influence on pain alleviation and joint functions. [16]

4. Glucosamine Helps In Alleviating The Symptoms Of Kashin-Beck Disease

Kashin-Beck Disease that is predominant in north-eastern and south-western parts of China, is a degenerative bone disease, which is characterized by cartilage breakdown similar to osteoarthritis. Therefore, treatment with glucosamine may help in improving the motility and reducing the pain associated with the inflammation.

Confidence Level: Moderate

In 2012, 251 patients with KBD were subjected to a cluster-randomized, placebo-controlled trial wherein they were treated with glucosamine hydrochloride, chondroitin sulphate, glucosamine hydrochloride-chondroitin sulfate combination, and placebo.

After 6 months, it was observed that the combination of glucosamine hydrochloride and chondroitin sulphate was more effective in reducing the pain and stiffness than placebo alone. [17]

Another study conducted in 2012, which involved 183 adult KBD patients showed that a daily dose of 1500mg of glucosamine for 6 weeks was helpful in reducing pain and improving physical functions.

The performance of glucosamine was comparable with that of Diclofenac and Naproxen. [18]

In 2010, a study involved 80 adult patients aged over 40 years, who were randomly categorized into two groups.

One group received a 1600mg oral mixture of glucosamine and chondroitin sulphate and the other received placebo, daily twice for a period of 8 months.

Narrowing of knee joint space was rather slow in the experimental group when compared to the controlled group. This implies that this combination can help in protecting the articular cartilage layer. [19]

5. Glucosamine is Helpful in Decreasing Collagen Degradation

Collagen degradation is caused due to inflammation and treating it with anti-inflammatory agents like glucosamine can help in reducing the severity of the damage. Glucosamine brings down collagen degradation by blocking lipid peroxidation reaction and oxidation of collagen matrix. [20]

Confidence Level: Moderate

In 2009, there was a study carried out which involved the evaluation of glucosamine's impact on the articular cartilage of athletes, whose joints are exposed to high levels of biomarkers for type II collagen degradation(CTX-II) and type II collagen synthesis (CPII).

The subjects were administered with 1.5g- 3g glucosamine daily for three months. After 3 months, it was observed that the levels of CTX-II had reduced. [21]

In 2013, 25 cyclists were chosen to study the impact of glucosamine on cartilage and bone metabolism. It was reported that 1.5g-3g of glucosamine exhibited chondroprotective action by reducing type II collagen degradation. [22]

6. Glucosamine Possesses Anti-Aging Properties

Glucosamine is necessary for the biosynthesis of hyaluronate, proteoglycans, glycoproteins and various other connective tissues that are responsible for the healthy skin structure.

Glucosamine can also have an impact on the skin's moisture content, wound healing properties and the appearance of the wrinkles. Glucosamine is also found to be helpful in addressing hyperpigmentation.

Confidence Level: Moderate

In 2017, a study was conducted in order to analyze the impact of glucosamine on skin aging. 8 healthy women who were less than 50 years old, were given 250mg glucosamine orally for 8 weeks.

After 8 weeks, it was observed that glucosamine had a positive effect on both the epidermal and dermal factors that were associated with aging. [23]

A 2006 study had reported that due to glucosamine's ability to stimulate the synthesis of hyaluronic acid, the former can speed up the wound healing process, impact the skin's moisture content and help in reducing the visibility of wrinkles.

As a tyrosinase inhibitor, glucosamine can also help in addressing skin pigmentation disorders. [24]

7. Glucosamine Helps in Reducing The Symptoms of Rheumatoid Arthritis

Unlike osteoarthritis, rheumatoid arthritis is an autoimmune disorder that damages the joints and spreads to other parts of the body. The severity of rheumatoid arthritis can be brought down with glucosamine administration.

Confidence Level: Moderate

In a 2007 study which involved 51 patients, 25 were treated with 1500mg glucosamine hydrochloride and remaining with placebo.

After 12 weeks, noticeable improvements were observed in the symptoms of rheumatoid arthritis. [25]

Animal studies have shown that glucosamine in combination with other biomolecules like N-acetyl glucosamine and vitamin E can suppress the inflammation and improve the functioning of the joints. [26] [27]

8. Glucosamine Positively Impacts The Cardiac Functions

Glucosamine may be helpful in improving cardiovascular health by reducing the inflammation in the blood vessels and promoting healthy cardiac functions.

Confidence Level: Low

Studies have shown that glucosamine may help in preventing inflammation in the blood vessels and reduce the risk of atherosclerosis [28] [29] and balance the calcium levels in the cardiac cells and protect them against damage. [30] [31] [32]

9. Glucosamine helps in the treatment of Inflammatory Bowel Disease

Inflammatory Bowel Disease is a disorder that arises due to glycosaminoglycan deficiency. Continued inflammation leads to erosions, swelling, and shortening of the intestinal glands. Glucosamine, being a powerful anti-inflammatory agent, can help in suppressing the inflammation and stabilizing the condition.

Confidence Level: Low

In a 2014 animal study, it was observed that, when mice with inflammatory bowel syndrome were treated with glucosamine oligosaccharides (chitooligosaccharides), the erosion and swelling had reduced and shortening and destruction of the intestinal gland was suppressed. [33]

10. Glucosamine helps in relieving lower back pain

Glucosamine is reported to be helpful in relieving the lower back pain caused due to disc degeneration. Glucosamine’s anti-inflammatory properties help in slowing down the cartilage degeneration and thereby subsiding the inflammatory reactions such as stiffness and pain.

Confidence Level: Low

In 2003, a research paper was published on how glucosamine along with chondroitin sulphate (CS) can address the disc degeneration. It was reported that oral glucosamine and CS are chondroprotective in function and these inhibit the cartilage breakdown.

It also reported that regular oral doses of these two molecules can promote cartilage regeneration in patients who are suffering from early stages of disc degeneration. [34]

Dosage of Glucosamine

The standard recommended dosage for glucosamine sulphate is 1,500 mg/day – 500mg of glucosamine three times a day. Research experiments talk up to administering 3,000 mg/day depending on the condition of the patient.

Glucosamine supplements are consumed along with the food. It is always safer to discuss with a healthcare professional before consuming glucosamine supplements. [35] [36]


Adverse effects

Glucosamine supplements are well tolerated with occasional GI disturbances like heartburn, diarrhea, nausea, and vomiting. Allergic reactions like angioedema, photosensitivity, and asthmatic crises have also been recorded in rare cases.

Safety during Pregnancy, Lactation, and Childhood

Due to insufficient data, it is advised that pregnant women, nursing mothers, and children

consult a healthcare professional before consuming glucosamine supplements.

Known Health Conditions

Glucosamine is reported to worsen asthma. Therefore, in order to avoid risks, people with known medical conditions are requested to consult a healthcare professional before using glucosamine supplements.

Possible interactions with drugs

  • Warfarin: Avoid consuming glucosamine while on warfarin (Coumadin). According to a few scientific reports, Glucosamine interacts with warfarin by increasing the effect of the latter. This may lead to bruising and bleeding, which might be fatal. [37]
  • Paracetamol: Glucosamine is reported to interact with paracetamol by increasing the bioavailability of the drug. [38]
  • Diabetic Medication: Primary reports have shown that glucosamine might reduce the efficacy of the diabetic medication and alter the blood glucose level in diabetics. However, more studies are required in this aspect.
  • Chemotherapy Drugs: Glucosamine is also said to interact with chemotherapy drugs such as etoposide, teniposide, and doxorubicin and bring their efficacy down.


There are no extensive studies conducted on the effects of glucosamine overdose in humans.

Dosage up to 3000mg/day is said to be safe with no adverse effects.

However, it is recommended that the patients do not consume more than what is recommended by their physician/nutritionist.

Shellfish Allergy

Individuals who are allergic to shellfish/seafood should be cautious while consuming glucosamine supplements, as glucosamine is largely derived from the shells of crabs, shrimps, and lobsters.

However, there have been no reports of any allergic reactions to shellfish-derived glucosamine so far.

Those who worry about allergic reactions can opt for vegetarian glucosamine that is derived from corn and Aspergillus.

However, it must be noted there is no evidence on the efficacy of vegetarian glucosamine.


Is Glucosamine a real Painkiller?

Glucosamine helps in reducing pain and other inflammatory reactions like edema and redness.

However, it does not work like other painkillers that alter the perception of pain. As an anti-inflammatory agent, glucosamine brings down the severity of inflammation in the joints and alleviates its symptoms.

In the case of osteoarthritis, patients are usually administered with NSAIDs and analgesics for pain.

NSAIDs are studied to cause various side effects with long term usage and analgesics are said to become ineffective with prolonged usage.

In this case, glucosamine can serve as a safer alternative with least side effects and maximum benefits. So yes, glucosamine can be called a pain killer that is both effective and safe.

Can Glucosamine Be Taken Long Term?

Studies have shown that long term usage of glucosamine does not cause any serious adverse effects in healthy individuals.

It can be used to address various symptoms of inflammation, and its long term usage is one of the ways to delay the progression of the inflammation.

Glucosamine is naturally synthesized in our bodies; however, as the age advances, the synthesis of glucosamine is reduced.

Supplementation of glucosamine can help in reducing the severity of inflammation in the joints by bringing down the cartilage degeneration.

No studies have shown that glucosamine can reverse OA, but it sure does help in coping with the symptoms.
