What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 3 of its 11 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (583 mg) without saying how much of each component you get.
  • “d-Glucosamine Sulfate Potassium Chloride” is listed as a grouped ingredient — the label gives one combined amount (667 mg) without saying how much of each component you get.

Glucosamine MSM Herbal contains 11 ingredients, including two forms of glucosamine (D-glucosamine sulfate and glucosamine sulfate potassium chloride), a proprietary blend with multiple herbal components, and individual nutrients. The active ingredients are calcium citrate, glucosamine, MSM, Eucommia, Chinese Yam, Drynaria, prepared Rehmannia, Molybdenum, Corydalis yanhusuo, Sichuan Teasel, and Boswellia serrata gum resin extract.

The inactive ingredients—sorbitol, stearic acid, modified cellulose gum, silica, and magnesium stearate—are fillers and binders that hold the tablet together.

Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: supports healthy joint function.
  • We looked for evidence on: Joint pain, Knee pain, Back pain, Osteoarthritis, Rheumatoid arthritis.
  • The strongest evidence on file: Glucosamine is rated "Likely Effective" for Osteoarthritis (Natural Medicines).
  • Also on file: Boswellia Serrata is rated "Possibly Effective" for Osteoarthritis.
  • Also on file: Boswellia Serrata is rated "Insufficient Reliable Evidence To Rate" for Rheumatoid arthritis (RA), Knee pain.

Calcium in this product is likely effective for osteoporosis and has been shown effective for kidney failure, upset stomach (dyspepsia), low blood calcium (hypocalcemia), and high potassium (hyperkalemia). Glucosamine is likely effective for osteoarthritis but has insufficient evidence for aging skin, back pain, colorectal cancer, or fatty liver disease.

Molybdenum is likely effective for molybdenum deficiency but lacks reliable evidence for acne, anemia, asthma, osteoporosis, or cancer. Boswellia serrata is possibly effective for osteoarthritis.

Prepared Rehmannia is possibly effective for chronic kidney disease but has insufficient evidence for anemia, allergies, bone health, diabetes, or diabetic kidney damage. We hold insufficient evidence for Corydalis yanhusuo's effectiveness for headache, constipation, depression, indigestion, or bacterial infection.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 4 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Calcium is generally well tolerated at recommended doses, though high amounts can cause problems. Most common side effects are belching, constipation, diarrhea, bloating, and stomach upset.

There is some concern that very high calcium intake (over 1500–2000 mg daily) might increase the risk of prostate cancer and possibly cardiovascular disease, though these findings have been questioned in research. Glucosamine is generally well tolerated but commonly causes bloating, constipation, cramps, diarrhea, heartburn, and nausea.

Rare serious concerns include allergic reactions—a review found 72% of glucosamine adverse events involved hypersensitivity, with 1.5% anaphylaxis—and asthma flare-ups in sensitive people. Boswellia serrata is generally well tolerated short-term and commonly causes abdominal pain, diarrhea, headache, heartburn, nausea, and itching.

Molybdenum is well tolerated at appropriate doses but very high supplemental amounts (rare) have caused psychosis and seizures in case reports. Prepared Rehmannia and Corydalis yanhusuo have limited human safety data.

d-Glucosamine Sulfate Potassium Chloride4 drug types · 170 drugs

Warfarin (Coumadin)

Glucosamine might increase the anticoagulant effects of warfarin and increase the risk of bruising and bleeding.
In two individual case reports, glucosamine/chondroitin combinations were associated with a significant increase in international normalized ratio (INR) in patients previously stabilized on warfarin. In one case, the increase in INR occurred only after tripling the dose of a glucosamine/chondroitin supplement from 500 mg/400 mg daily to 1500/1200 mg daily. Additionally, 20 voluntary case reports to the U.S. Food & Drug Administration (FDA) have linked glucosamine plus chondroitin with increased INR, bruising, and bleeding in patients who were also taking warfarin. There have also been 20 additional case reports to the World Health Organization (WHO) that link glucosamine alone to increased INR in patients taking warfarin. The mechanism of this interaction is unclear. Glucosamine is a small component of heparin, but is not thought to have anticoagulant activity; however, animal research suggests that it might have antiplatelet activity.

Likelihood Probable Evidence D
Topoisomerase Ii Inhibitors

Theoretically glucosamine may induce resistance to topoisomerase II inhibitors.
In vitro research suggests that glucosamine might induce resistance to etoposide (VP16, VePesid) and doxorubicin (Adriamycin) by reducing inhibition of topoisomerase II, an enzyme required for DNA replication in tumor cells. This effect has not been reported in humans.

Likelihood Possible Evidence D
Acetaminophen (Tylenol, Others)

Acetaminophen might interfere with the activity of glucosamine sulfate by interacting with the sulfate portion.
Anecdotal reports suggest that adding glucosamine to an acetaminophen regimen might decrease pain control in patients with osteoarthritis. Some research suggests that the sulfate portion of glucosamine sulfate might contribute to its effect in osteoarthritis. Since acetaminophen metabolism requires sulfur and reduces serum sulfate concentrations, acetaminophen could theoretically interfere with the action of glucosamine sulfate. Conversely, the administration of sulfate could theoretically decrease the effectiveness of acetaminophen in sulfate-deficient people by increasing its clearance.

Likelihood Possible Evidence B
Antidiabetes Drugs

Despite initial concerns, it is unlikely that glucosamine will interfere with the effects of antidiabetes drugs.
In vitro and animal research has suggested that glucosamine might increase insulin resistance or decrease insulin production. This has raised concerns that taking glucosamine might worsen diabetes and decrease the effectiveness of diabetes drugs. However, clinical research suggests that glucosamine does not have adverse effects on blood glucose or glycated hemoglobin (HbA1C) in healthy, obese, or type 2 diabetes patients.

Likelihood Unlikely Evidence B

Calcium Citrate18 drug types · 168 drugs

Ceftriaxone (Rocephin)

Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction. So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.

Likelihood Probable Evidence D
Dolutegravir (Tivicay)

Calcium seems to reduce levels of dolutegravir.
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation.

Likelihood Probable Evidence B
Elvitegravir (Vitekta)

Calcium seems to reduce levels of elvitegravir.
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation.

Likelihood Probable Evidence B
Aluminum

Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease. However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption.

Likelihood Possible Evidence B
Bictegravir/Emtricitabine/Tenofovir Alafenamide (Biktarvy)

Calcium might decrease levels of bictegravir/emtricitabine/tenofovir alafenamide by reducing its absorption when taken in a fasting state.
Advise patients that bictegravir/emtricitabine/tenofovir alafenamide and calcium can be taken together if taken with food. However, if taken on an empty stomach, bictegravir/emtricitabine/tenofovir alafenamide should not be taken with, or 2 hours after, calcium containing products.

Likelihood Probable Evidence D
Bisphosphonates

Calcium reduces the absorption of bisphosphonates.
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates.

Likelihood Probable Evidence C
Calcipotriene (Dovonex)

Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.

Likelihood Possible Evidence B
Digoxin (Lanoxin)

Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. However, one retrospective analysis of clinical data suggests that intravenous calcium does not increase the risk of dysrhythmias or mortality in patients receiving digoxin.

Likelihood Possible Evidence B
Diltiazem (Cardizem, Others)

Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.

Likelihood Probable Evidence D
Levothyroxine (Synthroid, Others)

Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Advise patients to take levothyroxine and calcium supplements at least 4 hours apart. Calcium reduces levothyroxine absorption, probably by forming insoluble complexes. Calcium carbonate supplements reduce effectiveness of levothyroxine in patients with hypothyroidism.

Likelihood Probable Evidence B
Lithium

Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients. Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.

Likelihood Possible Evidence B
Quinolone Antibiotics

Calcium seems to reduce the absorption of quinolone antibiotics.
Advise patients to take oral quinolones at least 2 hours before or 4-6 hours after calcium supplements or calcium-fortified foods. Taking calcium at the same time as oral quinolones can reduce quinolone absorption. Calcium binds to quinolones in the gut.

Likelihood Probable Evidence B
Raltegravir (Isentress)

Calcium may reduce levels of raltegravir.
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir. However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure.

Likelihood Possible Evidence B
Sotalol (Betapace)

Calcium seems to reduce the absorption of sotalol.
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes.

Likelihood Possible Evidence B
Tetracycline Antibiotics

Calcium seems to reduce the absorption of tetracycline antibiotics.
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut.

Likelihood Probable Evidence C
Thiazide Diuretics

Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Thiazides reduce calcium excretion by the kidneys. Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.

Likelihood Probable Evidence C
Verapamil (Calan, Others)

Theoretically, calcium may reduce the therapeutic effects of verapamil.
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.

Likelihood Probable Evidence D
Calcium Channel Blockers

Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects. But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers.

Glucosamine MSM Herbal by Planetary Herbals: Common Questions

Does Glucosamine MSM Herbal by Planetary Herbals interact with any medications?
Yes. Based on its ingredients, Glucosamine MSM Herbal has a known interaction with 1,374 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Glucosamine MSM Herbal contains 11 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is this safe to take while I'm pregnant?
Calcium is likely safe at recommended amounts in pregnancy, but glucosamine should be avoided because there isn't enough safety data. Prepared Rehmannia and Corydalis yanhusuo are best avoided too. Talk to your doctor or pharmacist before starting—they can give you personalized advice based on your health and what else you take.
Can I take this while breastfeeding?
Calcium and molybdenum at dietary amounts are generally okay while breastfeeding, but glucosamine, Corydalis yanhusuo, Boswellia serrata, and prepared Rehmannia don't have enough safety information—avoid them unless your doctor advises otherwise. Check with your provider first.
What does glucosamine do in this formula?
Glucosamine is likely effective for osteoarthritis (joint wear-and-tear). The product contains two forms of it—D-glucosamine sulfate and glucosamine sulfate potassium chloride—to support cartilage health.
Why are there two types of glucosamine in this?
D-glucosamine sulfate and glucosamine sulfate potassium chloride are two different forms of the same ingredient. The potassium chloride form may help with absorption and mineral balance.
What are the most common side effects I might feel?
From calcium: belching, constipation, diarrhea, bloating, or stomach upset. From glucosamine: bloating, constipation, cramps, diarrhea, heartburn, or nausea. From Boswellia: abdominal pain, diarrhea, headache, or heartburn. Most people tolerate it well, but if you have a sensitive stomach, take it with food.
Does this work for arthritis?
Glucosamine is likely effective for osteoarthritis, and Boswellia serrata is possibly effective. Calcium and molybdenum don't have established roles in arthritis treatment, though adequate calcium supports bone health overall.
