Glucosamine and chondroitin are two ingredients frequently seen on supplement labels.
They are often included in the same formula, but you may still wonder:
"What is the difference between them?", "What is MSM?", or "What should I look for when comparing supplements?"
Glucosamine and chondroitin are different compounds with their own characteristics.
Many supplements also combine them with a third ingredient,
MSM (methylsulfonylmethane).
In this guide, we explain the differences between glucosamine, chondroitin and MSM, their relationship with foods and natural sources, the difference between glucosamine HCl and glucosamine sulphate, and the main points to check when comparing supplement formulas.
Glucosamine, Chondroitin and MSM at a Glance
First, here is a simple comparison of the three ingredients.
| Ingredient |
What is it? |
Common label wording |
| Glucosamine |
A type of amino sugar |
Glucosamine HCl / Glucosamine Sulfate |
| Chondroitin |
A type of glycosaminoglycan |
Chondroitin Sulphate |
| MSM |
An organic sulphur-containing compound |
Methylsulfonylmethane |
Each has a different chemical structure and characteristics, which is why
supplements combining two or all three ingredients
are commonly available.
What Is Glucosamine?
Glucosamine is a type of amino sugar.
It also occurs naturally in the human body and is known as a building block involved in glycosaminoglycan-related structures.
Although the word "sugar" may bring table sugar or glucose to mind, glucosamine is a different type of compound and is
an amino sugar naturally present in the body.
Glucosamine Occurs in Nature and in the Body
Glucosamine is widely known because of supplements, but it is also naturally present in living organisms and in the human body.
Supplements provide glucosamine in measured amounts and in several different forms.
Glucosamine HCl vs Glucosamine Sulphate
When comparing glucosamine supplements, you may see labels such as:
- Glucosamine HCl (Glucosamine Hydrochloride)
- Glucosamine Sulfate / Sulphate
Both contain glucosamine, but the chemical form is different.
For this reason, when reading a supplement label it can be useful to look beyond the number of milligrams and also check
which form of glucosamine is being used.
Quick Tip: What Does "HCl" Mean?
The abbreviation HCl on a supplement label refers to
hydrochloride.
For example, "Glucosamine HCl" means glucosamine hydrochloride.
The correct abbreviation is HCl, with a lowercase "l" at the end.
It is a useful detail to recognise when reading overseas supplement labels.
What Is Chondroitin?
Chondroitin is another ingredient frequently seen alongside glucosamine.
In supplements, it is commonly provided as
Chondroitin Sulphate.
Chondroitin sulphate belongs to a group of compounds known as
glycosaminoglycans (GAGs).
It is also naturally present in the body and is characterised by its long-chain carbohydrate structure.
Quick Tip: "Sulphate" or "Sulfate"?
When reading international supplement labels, you may see both
Chondroitin Sulphate and
Chondroitin Sulfate.
These are spelling variations used in different forms of English and refer here to the same ingredient:
chondroitin sulphate.
Health Life Joint Formula uses the spelling
Chondroitin Sulphate.
What Is the Difference Between Glucosamine and Chondroitin?
Glucosamine and chondroitin are often mentioned together, but their structures and characteristics are different.
- Glucosamine: a relatively small amino sugar
- Chondroitin sulphate: a glycosaminoglycan made up of repeating sugar units
Understanding this distinction makes it easier to understand why supplements frequently combine
glucosamine + chondroitin
in a single formula.
Why Are Glucosamine and Chondroitin Often Combined?
Glucosamine and chondroitin have both been studied internationally for many years.
Because they are different ingredients, supplement manufacturers frequently combine
glucosamine and chondroitin in the same formula.
They have been studied both individually and in combination, and today the pairing is widely recognised in the supplement market.
Another ingredient frequently added to this combination is
MSM.
What Is MSM (Methylsulfonylmethane)?
MSM stands for
Methylsulfonylmethane.
It is an organic compound containing sulphur and is known to occur naturally in the environment.
The three-letter abbreviation can make the ingredient sound complicated, but MSM is simply the shortened form of its chemical name, methylsulfonylmethane.
It is commonly included in supplements together with glucosamine and chondroitin.
Quick Tip: Is the "Sulphate" in Chondroitin the Same as the Sulphur in MSM?
The word "sulphate" appears in chondroitin sulphate, while MSM is described as a compound containing
sulphur.
Although the terminology may look similar,
chondroitin sulphate and MSM are separate compounds with different chemical structures.
It is easiest to read them as two separate ingredients when checking a supplement label.
Glucosamine + Chondroitin + MSM Formulas
Many supplements now combine:
- Glucosamine
- Chondroitin
- MSM
A combined formula allows
all three ingredients to be taken in one product rather than purchasing them separately.
When comparing products, it is useful to check
which form of each ingredient is used and how many milligrams are provided per capsule.
How Is Glucosamine Related to Food and Natural Sources?
Glucosamine is also related to naturally occurring materials.
In particular,
chitin, which is found in the shells of crustaceans such as prawns, shrimp and crabs, is a natural material closely associated with glucosamine production.
Supplement-grade glucosamine may be produced from crustacean-derived materials or by fermentation and other manufacturing methods.
This means that even products labelled "glucosamine" may use
different raw materials and manufacturing methods.
Is Chondroitin Found in Food?
Chondroitin sulphate occurs naturally in animal cartilage and connective tissues.
Foods containing cartilage may also contain chondroitin-related compounds, while supplements provide products in which
the amount of chondroitin sulphate is clearly stated on the label.
Because raw materials and amounts vary between products, checking the ingredient panel makes it easier to understand the characteristics of each formula.
5 Things to Check When Comparing Glucosamine and Chondroitin Supplements
1. Check the Form of Glucosamine
Look for whether the product contains
Glucosamine HCl or
Glucosamine Sulfate / Sulphate.
Reading the full ingredient name gives you more information than looking at the word "glucosamine" alone.
2. Check the Amount per Capsule
When comparing formulas, check the
amount provided per capsule.
Then compare that figure with the recommended daily intake to understand how the formula is designed to be used.
3. Check the Amount of Chondroitin
Look for how many milligrams of
Chondroitin Sulphate
are provided.
This makes different products easier to compare.
4. Look at Additional Ingredients Such as MSM
Some formulas combine glucosamine and chondroitin with MSM or other ingredients.
Checking
what is included and how much of each ingredient is provided
gives you a clearer picture of the product's formulation.
5. Consider How Easy It Is to Include in Your Routine
Daily serving size, capsule count and total pack size vary between supplements.
Checking
how many capsules are taken each day and approximately how long one bottle lasts
can make it easier to find a product that fits your routine.
Health Life Joint Formula: Three Ingredients in One Formula
The
Health Life Joint Formula
available from Brilliant Life Products NZ combines all three ingredients discussed in this guide.
The formula contains:
- Glucosamine HCl
- Chondroitin Sulphate
- MSM (Methylsulfonylmethane)
This allows
glucosamine, chondroitin and MSM to be included together in one capsule-based formula.
How Much Is in One Capsule?
Each capsule of Health Life Joint Formula contains:
- Glucosamine HCl 1,000mg
- Chondroitin Sulphate 400mg

The formula clearly states
the amount of each ingredient per capsule,
making it easy to see exactly what the product contains.
What Does That Equal per Daily Serving?
The manufacturer's directions are
2–3 capsules daily with meals.
Based on that serving size:
| Ingredient |
2 Capsules |
3 Capsules |
| Glucosamine HCl |
2,000mg |
3,000mg |
| Chondroitin Sulphate |
800mg |
1,200mg |
