Chondroitin and Glucosamine Don't Work — But MSM Does
Glucosamine and chondroitin supplements are everywhere. Based on how these molecules are actually processed by the body, they cannot work as advertised. MSM is different. Here's the biochemical reason why.
Joint supplements are a large category. Glucosamine and chondroitin are the most commonly marketed options. Here's the problem: they are biochemically incapable of delivering what the marketing claims.
Why Glucosamine and Chondroitin Can't Work
Glucosamine and chondroitin are composed of carbohydrate and amino acid elements. They are, structurally speaking, fragments of proteins.
Before anything we ingest can be absorbed into the bloodstream, the digestive system must break it down into its simplest components. Proteins must be broken into amino acids. Carbohydrates must be broken into glucose. There are no exceptions to this process — it applies regardless of the source or form.
By the time glucosamine or chondroitin is broken down to the point where it can be absorbed, it has been reduced to the same simple components you'd get from eating any protein and carbohydrate source. The claim that these products specifically replenish cartilage or synovial fluid by direct delivery makes no biochemical sense. The molecules don't survive digestion intact.
Eating a bowl of oatmeal supplies the same relevant substrate. You don't need to pay premium prices for branded "joint supplements" containing these molecules.
What MSM Actually Does
MSM (methylsulfonylmethane) is an organic sulfur compound — not a carbohydrate or protein fragment. This is a different category of molecule entirely.
The anti-inflammatory properties of sulfur have been documented for centuries. Modern research has confirmed multiple mechanisms:
- 1. Anti-inflammatory action: MSM has documented anti-inflammatory properties in joint tissue
- 2. Osteoclast inhibition: Research indicates MSM inhibits osteoclast activity, reducing bone resorption (the process that contributes to bone loss in aging and osteoporosis)
- 3. Glucose tolerance support: Studies have shown MSM may help stabilize blood sugar regulation in individuals with impaired glucose tolerance
When joint supplements containing MSM produced results that plain glucosamine/chondroitin didn't, the MSM was the active component. The glucosamine and chondroitin in those products were not contributing.
Joint Prevention Is More Effective Than Treatment
The more important insight from any joint injury experience: warmth prevents injury more effectively than supplements treat it.
- Always warm up the specific joints that will be loaded heavily before training
- If training in cold conditions or in air-conditioned gyms, use compression sleeves on vulnerable joints
- A heat-generating topical ointment (like Nikoflex) before training is cheap, effective, and fast
- Never run cold in the morning without joint warmup — this is how acute joint injuries happen
If you're treating rather than preventing, the evidence for MSM supplementation is reasonable. For glucosamine and chondroitin: don't bother.
