Product Review: Glucosamine, Chondroitin, and MSM Supplements for Joint Health

Initial Posting: 5/5/12 Updated 5/8/12
What It Is:
Glucosamine, chondroitin sulfate, and MSM (methylsulfonylmethane) occur naturally in the body. The glucosamine used in supplements is typically derived from the shells of shrimp or crabs although a corn source is also available. Glucosamine is available in a variety of chemical forms, such as glucosamine hydrochloride and glucosamine sulfate. These vary in terms of the amount of actual glucosamine available for use in the body from an equal weight of each form (See ConsumerTips™ for Glucosamine for more information). Chondroitin sulfate is generally derived from pig or cow cartilage, but even shark and chicken cartilage has been used. Chondroitin-like mucopolysaccharides from algae are also available. MSM is synthetically produced.

What It Does:
Glucosamine and Chondroitin:
Glucosamine and chondroitin sulfate supplements are used to slow the progression of osteoarthritis — the deterioration of cartilage between joint bones — and to reduce the associated pain. A study sponsored by the National Institutes of Health (NIH) called the Glucosamine/Chondroitin Arthritis Intervention Trial (or GAIT study), showed that the combination of glucosamine and chondroitin sulfate seems to be effective in osteoarthritis patients with moderate to severe knee pain, although not those with mild pain.

A well-controlled study of glucosamine sulfate (1,500 mg per day) versus placebo for lower back pain caused by osteoarthritis showed that both glucosamine and placebo improved symptoms reported by patients. However, there was no significant difference in the level of improvement between the groups, suggesting that glucosamine is not truly effective for lower back pain (Wilkens, JAMA 2010).

A 2007 review of several past, large-scale studies of chondroitin alone concluded that it did not provide a benefit. However, a six-month study of chondroitin sulfate (800 mg once daily) versus placebo in patients with hand osteoarthritis showed a significantly greater decrease in hand pain and improvement in hand function among those taking chondroitin sulfate (Gabay, Arth & Rheum 2011). The duration of morning stiffness was also slightly reduced. These benefits were not noticeable until after 3 months of treatment. There was no significant difference in grip strength or the amount of analgesic used by patients. The chondroitin tested in the study was a tablet containing highly purified (95% pure) chondroitin of fish origin and is marketed as Chondrosulf (IBSA, Switzerland) in Europe where it is approved as a “Symptomatic Slow Acting Drug for Osteoarthritis” (IBSA website – accessed 9/21/2011).

Glucosamine is thought to promote the formation and repair of cartilage. Chondroitin is believed to promote water retention and elasticity in cartilage and inhibit enzymes that break down cartilage. In veterinary medicine, glucosamine and chondroitin, often in combination, are commonly used in the treatment of degenerative joint disease — typically in older dogs and cats as well as in horses. (See separate review of Joint Health Supplements for Dogs, Cats, and Horses.

MSM:
MSM is used primarily for treating pain associated with osteoarthritis and has been proposed for treating other conditions including rheumatoid arthritis, inflammation of the bladder wall (interstitial cystitis), snoring, muscle spasm, and cancer. All of these uses for MSM, including those for arthritis, are based on limited research, so its effectiveness hasn’t been well established. Many additional claims are found on MSM products, including skin-softening and nail-strengthening effects, but none of these are well supported by research. The mechanism by which MSM may work isn’t well understood, although it is known to contribute sulfur to the body, which can then be used to synthesize certain amino acids (building blocks for proteins), and it can act as an antioxidant. As a veterinary medicine, MSM is used to treat muscle and tendon soreness and inflammation in horses — see separate review of Joint Health Supplements for Dogs, Cats and Horses.

See the ConsumerTips™ later in this report for insightful information on buying and using these supplements. For more information about the clinical evidence for these and other supplement ingredients, see the article on Osteoarthritis on this website. Also see ConsumerLab.com’s Product Review of SAMe Supplements, as SAMe can help treat osteoarthritis pain.

Quality Concerns and What CL Tested for:
Glucosamine and Chondroitin:
Although prior testing has shown the vast majority of glucosamine products to meet label claims, glucosamine from shellfish such as shrimp and crabs may potentially be contaminated with lead. Chondroitin, on the other hand, is an ingredient with which ConsumerLab.com has found problems in the past — with products not always providing the amount claimed of this expensive ingredient.

There had been concern with bovine (cow) sources of chondroitin several years ago on account of Mad Cow disease (known scientifically as bovine spongiform encephalitis or BSE). There have not been any reported cases of the disease from chondroitin and the risk seems to be miniscule because the prion thought to be the causative agent of the disease exists only in very low levels in cartilage; it’s most abundant in nervous and glandular tissues. The issue of BSE, however, may be avoided by choosing a product made from the cartilage of other animals, such as pigs (now a common source), chickens, or sharks.

MSM:
MSM is chemically related to DMSO (dimethyl sulfoxide), which has been used in ways similar to MSM. Unlike MSM, however, DMSO is a chemical solvent. DMSO was found to cause a range of adverse reactions and is no longer approved as a supplement. It still has limited use, however, for those under medical supervision.

Because no government agency is responsible for routinely testing glucosamine, chondroitin, and MSM supplements for their contents or quality, ConsumerLab.com independently evaluated several human and veterinary products to determine whether they contained the amounts of these ingredients stated on their labels. All products were also tested for lead contamination. MSM products were additionally tested for DMSO contamination. Although not thought to be a health risk in small amounts, DMSO in products indicates poor-quality manufacturing. In addition, all tablets and caplets (excluding chewable or time-release) were tested for their ability to properly disintegrate (“break-apart”).

What CL Found:
Among the 22 supplements ConsumerLab.com selected and tested, only 18 met quality standards and FDA labeling requirements. Through ConsumerLab.com’s Voluntary Certification Program, in which products undergo the same testing, an additional 20 products were found to meet quality standards.

No problems were found with the MSM content of the selected products (and none contained an unacceptable level of DMSO), but among the 21 products claiming to contain glucosamine and/or chondroitin, four products (19%) failed to pass ConsumerLab.com’s review due to lead contamination, less ingredient than labeled, or failure to meet other FDA labeling requirements. All tablet and caplet products were found to properly break apart in solution (disintegrate).

The reasons why products failed are described below and in the results table:

Whole Foods Glucosamine and Chondroitin Complex was contaminated with 13.2 micrograms of lead per daily serving. This far exceeds the 0.5 mcg limit set by the State of California (the only state to set a limit) which nearly all other products did not exceed. Products sold in California that exceed this limit are required to carry a warning label regarding lead. While toxicity is not likely in adults from using from this product, lead accumulates in the body (in bones) and, at high levels, can adversely affect the nervous system and increase blood pressure. Children are particularly sensitive to lead and should not be exposed to more than 6 mcg in total per day.
KAL Glucosamine Chondroitin MSM was also contaminated with lead, although at a lower level than the Whole Foods product. It was found to contain 1.7 micrograms of lead per daily serving.
TR CAPS TR Joint Plus Caps was found to contain only 71.5% of its claimed chondroitin.
Maximum Strength DONA Crystalline Glucosamine Sulfate contained its claimed amount of glucosamine but its label lacked a required shellfish allergen warning statement (as glucosamine is made from crab shell and some people may be allergic) and the product included an ingredient (Eudragit RL) which has not been approved for use in supplements in the U.S. — although it is approved for use in drugs. The Supplement Facts panel was also not properly written: listing a daily serving of two caplets but showing the amount of glucosamine in only one caplet. This product is apparently sold in Europe as well as the U.S.

Why are some of these supplements contaminated with lead? It is hard to know for sure, but a likely source is the crab shells from which glucosamine is made, which can be contaminated. Minerals and botanical ingredients also have the potential for lead contamination. The Whole Foods products contained glucosamine, as well as calcium (330 mg/day) and an unlisted amount of peppermint leaf. Every supplement manufacturer is required to test their ingredients or finished product for lead contamination. However, under current law, the manufacturer sets its own limit based on what is considers acceptable. Some manufacturers have advocated a limit of 10 mcg per daily serving, much higher than the State of California permits without a warning label. ConsumerLab.com has protested against such a high level.

Why do some chondroitin products contain less chondroitin than claimed? Some manufacturers may rely on non-specific tests, such as the “CPC (cetyl pyridinium chloride) titration method” or “size-exclusion chromatography method” when evaluating chondroitin. These tests can easily be tricked by other compounds that are not chondroitin. Real chondroitin is relatively expensive. An ingredient supplier might sell lower priced “chondroitin” to which compounds have been added to fool these tests. A manufacturer looking to cut corners might buy lower cost material “certified” with a non-specific test and, as a result, end up making products with no or little real chondroitin. ConsumerLab.com evaluated chondroitin products using a more specific, validated method known as the “enzymatic HPLC method.” For each product that failed to contain its listed chondroitin, re-testing was performed in a second independent laboratory for confirmation (see How Products Were Evaluated).

Cost comparisons
The cost of supplements for joint health vary considerably – and paying more doesn’t necessarily mean you are getting a better product. If you just want glucosamine, Puritan’s Pride Premium Glucosamine HCL at 12 cents per day, was, by far, the least expensive supplement. Other products with glucosamine (without chondroitin or MSM) were much more expensive (over $1 per day), although many of them include additional ingredients of some potential benefit, such as turmeric (or curcumin) and boswellia. A potential downside to the Puritan’s Pride product, however, is that it is a single daily pill while most clinical trials have divided the dose into more than one pill per day.

Among MSM products, Doctor’s Best Best MSM 1500 was the least expensive, at just 6 cents per 1,500 mg.

If you are looking for both glucosamine and chondroitin, the least expensive supplement providing 1,500 mg of glucosamine and 1,200 mg of chondroitin (the combination most commonly recommended) was Simply Right Triple Strength Glucosamine and Chondroitin (sold at Sam’s Club) at a daily cost of 17 cents. 21st Century Glucosamine 750 Chondroitin 500 Triple Strength was the next least expensive (22 cents per day).

To get glucosamine and MSM, the least expensive product was, by far, NOW Vegetarian Glucosamine & MSM. The suggested 2 capsule serving costs 20 cents. This serving provides 1,000 mg each of glucosamine and MSM. (Increasing the dose to 3 capsules per will provide the generally recommended dose of 1,500 mg of glucosamine.) The other two products in this category cost $1.30 or more per daily serving.

If you want all three of the reviewed ingredients – glucosamine, chondroitin, and MSM – the lowest cost for a serving providing at least 1,500 mg of glucosamine and 1,200 mg of chondroitin is about 40 to 60 cents, available from products such as GNC Triflex, GNC Triflex Fast-Acting, Jarrow Formulas Glucosamine + Chondroitin + MSM, or Vitamin Shoppe® Joint Solutions Triple Strength Glucosamine & Chondroitin with MSM. The amounts of MSM in these products ranges, but the highest amount (900 mg) is in GNC Triflex. Interestingly, the most expensive product didn’t even contain its listed amount of chondroitin: TR CAPS TR Joint Plus Caps 8 Hour Time-Release cost $2.50 for the full 3 tablet daily serving but, as noted earlier, contained only 71.5% of its listed chondroitin.

Some triple-combination products do not specify the amounts of chondroitin and MSM they contain; instead, they include within proprietary blends, formulas, or complexes. While there may be value to some of these blends, you won’t really know what you are getting. For example, we checked Nutrilite Glucosamine-7’s blend, which turned out to provide a substantial amount of MSM (1,636 mg per daily serving) but not a lot of chondroitin (79.6 mg). Conversely, a daily serving of Nature’s Bounty Flexamin’s blend contained a little more chondroitin (234 mg per daily serving) but less MSM (132.2 mg). Whenever possible, ConsumerLab.com suggests purchasing products that specify how much they contain of each ingredient.

Test Results by Product:
Listed alphabetically within each product group below are test results for forty-two supplements of which ConsumerLab.com selected twenty-two. Twenty were tested at the request of their manufacturers/distributors through CL’s Voluntary Certification Program and are included for having passed testing. Also listed is one product similar to another that passed but is sold under a different brand name.

Shown for each product are the claimed amounts of glucosamine, chondroitin, and MSM and the suggested daily serving on its label. Additional notable ingredients are found in the last column, along with cost comparisons. Products that passed all tests are indicated as Approved in the third column; if a product failed testing, the reason is explained in red text.

A separate review of Joint Health Supplements for Dogs, Cats, and Horses is available, as is a review of SAMe supplements, which are also used for treating osteoarthritis.

ConsumerTips™:

What to Consider When Buying and Using:
Glucosamine & Chondroitin:
Glucosamine in supplements can be purchased in different chemical forms. Glucosamine hydrochloride (HCl) is the form that has been used most often in studies where glucosamine is combined with chondroitin. Glucosamine sulfate (more correctly called glucosamine sulfate 2-KCl (the KCl stands for potassium chloride) or glucosamine sulfate 2-NaCl (the NaCl stands for sodium chloride)) are the forms that have been used most often when glucosamine alone has been studied. There appears to be no conclusive evidence that one form is better than another. However, the amount of true (or “free”) glucosamine per gram of each compound varies greatly. In fact, 1,500 mg of glucosamine hydrochloride actually yields 1,246 mg of free glucosamine while 1,500 mg of glucosamine sulfate with 2 NaCl or 2 KCl yield, respectively, only 938 mg or 888 mg of free glucosamine. Although the hydrochloride form provides more free glucosamine than the sulfate forms, 1,500 mg per day of either form appears to be effective. People watching their salt intake may, however, want to avoid products made with the form that includes NaCl (sodium chloride).

Chondroitin is typically sold as chondroitin sulfate, which is also the form that’s been used in most studies. About 1,200 mg of chondroitin sulfate is recommended per day. Chondroitin sulfate is usually in a salt form to help stabilize it, so don’t be concerned if you see “sodium chondroitin sulfate” on the label or “calcium chondroitin sulfate.” These are the complete chemical names — although not all manufacturers use them — and the active ingredient, chondroitin sulfate, is the same. Supplement labels typically provide the amount of “free” chondroitin in the product, but some products do not make this adjustment. For example, a label indicating 1200 mg of chondroitin sulfate (90% by USP method) is really only providing 1,080 mg of actual chondroitin after adjusting for 90% purity.

Be aware that 1,200 mg of chondroitin sulfate from the sodium salt form will contribute 105 mg per day of sodium. To reduce your sodium intake, consider products made with the calcium salt form. With that form you’ll add about 191 mg of calcium per day to your diet instead of sodium.

Chondroitin can vary in terms of its purity, which tends to range from about 80 to 90%. The GAIT study sponsored by the NIH used chondroitin sulfate made by Bioberica which is believed to be 95% pure. The manufacturer of CosaminDS (a glucosamine/chondroitin combination product which is Approved in this Review) claims to be the exclusive licensee for this form of chondroitin. Chondroitin can also vary in terms of the chain length (and molecular weight) of its components — although the clinical significance of this is not well known. Results of laboratory studies with cell cultures indicate that shorter length molecules are better absorbed, but it is possible that longer length molecules are also digested to shorter length units. It is, therefore, difficult to say whether either form works better than the other.

Some products mention in their labeling that they contain chondroitin A which is a subcomponent of the larger chondroitin polysaccharide. This is probably of little importance. All chondroitin from cow or pig sources contain combinations of chondroitin A (or chondroitin 4 sulfate), chondroitin C (or chondroitin 6 sulfate) and a non-sulfated component.

Both glucosamine and chondroitin should be taken in divided doses throughout the day (that is, 500 mg of glucosamine HCl or sulfate and 400 mg of chondroitin sulfate three times per day or 750 mg glucosamine HCI or sulfate and 600 mg chondroitin sulfate two times per day). Because the amount of glucosamine or chondroitin per pill varies across products, the number of pills needed daily varies and this should be considered when comparing the costs of products.

For treating symptoms of osteoarthritis of the hand, 800 mg once daily of a highly purified (95% pure) chondroitin sulfate has been used (Gabay, Arth & Rheum 2011).

Some glucosamine-chondroitin products may contain manganese (which may potentially aid bone formation). The manganese levels in such products typically exceed the recommended intake, which is 2.3 mg per day for men and 1.8 mg per day for women — an amount similar to that consumed in the typical American diet. Too much manganese (over 11 mg per day) for an extended period of time carries a risk of neurological side effects. While this amount of manganese is not dangerous if taken just during a few weeks of initial therapy, it should not be exceeded for an extended period of time.

Beneficial effects from these products may take anywhere from several weeks to 3 months, and the products aren’t likely to help those with severe osteoarthritis — where cartilage has worn down so much that bones rub against bones. Losing weight and switching from high-impact to low-impact sports are also advised for people with osteoarthritis.

If a positive response is not experienced within 3 months, continuing with the supplement or increasing the dose is not indicated. If the supplements are having a beneficial effect, it may be possible to reduce the dose after the first few months. A person under 200 lbs with a positive response to the full dose (1500 mg glucosamine and 1,200 mg chondroitin per day) could try reducing the dose to 1,000 glucosamine and 800 of chondroitin. Those under 115 lbs could try going to 500 glucosamine and 400 chondroitin. If symptoms return, they should return to the full dosage. Those over 200 lbs should stay on the full dosage.

MSM:
There are few well-controlled published clinical studies for MSM, so it’s difficult to determine the optimal dose. The most commonly suggested daily dose is 2 grams. However, recommendations can range from 500 mg to 3 grams (1,000 mg = 1 gram). Occasionally, recommendations go as high as 8 grams/day.

High-quality MSM is an odorless white crystalline powder. When improperly manufactured, it can be contaminated with DMSO, which has a faint sulfur-like or garlic smell. Some products claim as little as 167 mg of MSM per pill; others, as much as 1,500 mg. When buying an MSM product, consider this variation.

Concerns and Cautions:
Glucosamine and Chondroitin:
Glucosamine and chondroitin, taken in appropriate amounts, are generally considered safe for healthy people not taking other medications, but be aware that, in some individuals, glucosamine can cause gastrointestinal discomfort, drowsiness, skin reactions, and headache and chondroitin can occasionally cause stomach upset.

Glucosamine is an amino sugar, so it may theoretically affect blood sugar levels. However, a recent clinical study did not find evidence of such an increase. Because the glucosamine in supplements is commonly derived from shrimp or crab shells, people allergic to shellfish may experience an allergic reaction to these products. A vegetable-based glucosamine is now available, sold under the trademarks Regenasure and GreenGrown.

Chondroitin is similar in structure to the blood-thinning drug heparin, so use of chondroitin with blood-thinning drugs or daily aspirin therapy may cause bleeding in some people. There are also reports of glucosamine and glucosamine/chondroitin affecting coagulation, increasing the INR (international normalized ratio) and the risk of bruising or bleeding in people using warfarin (Coumadin). If you use blood-thinning drugs, be sure to let your healthcare provider know if you take glucosamine or chondroitin, the dosage, and if you change the dosage.

Chondroitin sulfate is a component of a substance called versican that appears to support the spread of prostate cancer. While chondroitin sulfate itself has not been shown to have this effect, men with, or at risk for, prostate cancer may want to avoid chondroitin sulfate until more is known.

If you need to watch your sodium intake, consider choosing a product that does not use the sodium forms of glucosamine and chondroitin, as discussed above.

Before starting on any supplement for joint pain, consult a physician to be sure of your diagnosis. This is particularly important with hip pain, which may be caused by rheumatoid arthritis, infection, damaged blood supply, gout or other diseases for which treatment with glucosamine, chondroitin, or MSM would be inappropriate.

MSM:
MSM is generally safe when taken at recommended dosage levels, but be aware that MSM occasionally causes nausea, diarrhea, or headache. MSM may also have an aspirin-like effect and shouldn’t be used by patients already taking blood-thinning drugs, unless medically supervised. The safety of MSM hasn’t been evaluated for children or for women who are pregnant or breast-feeding, so individuals in these groups should avoid using MSM.
