Glutamine is an amino acid that plays a role in immune function and may help with sickle cell disease and recovery from critical illness. Glucosamine sulfate is used primarily for osteoarthritis joint support.

Potassium is an essential mineral that helps regulate heart rhythm, muscle function, and fluid balance. The product contains no inactive ingredients listed.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
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: muscle energy production and muscle mass maintenance.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Muscle breakdown, Muscle cramps, Muscle strength, Physical performance — and 4 related terms.
  • The strongest evidence on file: Glucosamine is rated "Likely Effective" for Osteoarthritis (Natural Medicines).
  • Also on file: Creatine is rated "Possibly Effective" for Athletic performance, Muscle strength, Sarcopenia.
  • Also on file: Glutamine is rated "Possibly Ineffective" for Athletic performance.

Creatine is possibly effective for muscle strength, athletic performance, and sarcopenia (age-related muscle loss), as well as for cerebral creatine deficiency syndromes. It's been rated possibly ineffective for Huntington disease and osteopenia.

Glutamine is effective for sickle cell disease and possibly effective for HIV/AIDS-related wasting, recovery after surgery, and critical illness from trauma. Glucosamine is likely effective for osteoarthritis but has insufficient evidence for aging skin, back pain, cancer, or fatty liver disease.

Potassium has no effectiveness ratings in our data — it's an essential nutrient rather than a treatment for a specific condition.

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 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Creatine is generally well tolerated in healthy adults but requires caution if you have kidney problems — those with kidney disease should be careful. It should be avoided during pregnancy and breastfeeding because safety hasn't been established.

The most common side effects are dehydration, diarrhea, gastrointestinal upset, muscle cramps, and water retention. Glutamine is generally well tolerated but should be used only under medical supervision if you have kidney or liver disease; it's not recommended in pregnancy without a doctor's recommendation, and the same applies to breastfeeding.

Common side effects include bloating, constipation, diarrhea, nausea, and headache. Glucosamine is generally well tolerated but should be avoided during pregnancy and breastfeeding due to insufficient safety data.

Gastrointestinal side effects (bloating, constipation, diarrhea, nausea) are most common, and rare allergic reactions including asthma exacerbation have been reported. Potassium from food is safe, but supplements can cause dangerously high blood levels, especially in people with kidney disease.

During pregnancy, dietary potassium is fine but supplements need medical guidance; the same applies to breastfeeding. High potassium can cause heart rhythm problems, low blood pressure, nausea, and vomiting.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 3 of the 4 matched ingredients can interact with medications — Glucosamine, Potassium, Glutamine.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; seizure medications; diabetes medications.
  • For scale: 282 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking Myo-Gen, double-check with your doctor or pharmacist if you take warfarin or other blood thinners (Major concern with glucosamine). Also flag any anticonvulsants or seizure medications (Moderate with glutamine), potassium-sparing diuretics, ACE inhibitors, or ARBs (Moderate with potassium), cancer chemotherapy drugs like etoposide or doxorubicin (Moderate with glucosamine), or acetaminophen or antidiabetes medications (Minor with glucosamine).

If you have kidney disease or take any regular medication, this conversation is essential.

Each ingredient & the kinds of drugs it affects

For each ingredient in Myo-Gen with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Glucosamine Sulfate4 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
Glucosamine Sulfate full monograph & interactions

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Likelihood Likely Evidence C
Potassium full monograph & interactions

Glutamine1 drug type · 50 drugs

Anticonvulsants

Theoretically, glutamine might antagonize the effects of anticonvulsant medications.
Glutamine is metabolized to the excitatory neurotransmitter glutamate. Glutamate might have antagonistic effects with anticonvulsant drugs. However, this interaction has not yet been reported in humans.

Myo-Gen by Douglas Laboratories: Common Questions

Does Myo-Gen by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Myo-Gen has a known interaction with 282 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Myo-Gen contains 4 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 it safe to take Myo-Gen if I'm pregnant or breastfeeding?
The safety data varies by ingredient. Creatine should be avoided during pregnancy and breastfeeding because safety hasn't been established. Glutamine isn't recommended in pregnancy or while breastfeeding without a doctor's recommendation. Glucosamine is best avoided during both periods. Potassium from a normal diet is fine, but supplements need medical guidance in both situations. Talk with your doctor or pharmacist about your specific needs.
What are the most common side effects?
The ingredients in this product can cause gastrointestinal effects — bloating, diarrhea, constipation, nausea, and abdominal discomfort are the most frequently reported. Creatine may also cause muscle cramps and water retention. Most people tolerate it well, but if you experience persistent stomach upset, reduce the dose or stop and check with your pharmacist.
Can I take this if I have kidney disease?
No — all three of the ingredients with safety cautions (creatine, glutamine, and potassium) require careful handling or are risky in kidney disease. Potassium especially can build up dangerously in your blood if your kidneys aren't working well. Do not take this without explicit approval from your doctor.
Does glucosamine in this product really help with joint pain?
Glucosamine sulfate is rated likely effective for osteoarthritis. However, if you take acetaminophen (Tylenol) for pain, it may slightly reduce how well glucosamine works, so it's worth discussing that combination with your pharmacist.
What is glutamine supposed to do in this product?
Glutamine is an amino acid. It's effective for sickle cell disease and possibly effective for recovery after surgery, trauma, or critical illness, and for HIV/AIDS-related wasting. It's included here likely for its role in muscle and immune support.
Why is there potassium in a muscle-support product?
Potassium is an essential mineral that helps regulate muscle function and heart rhythm. It's often included in athletic or muscle-support formulas for that reason. However, it's important — if you take blood pressure or heart medications, potassium supplements can raise your levels too high, so check with your doctor first.
