General Side Effects of Glucosamine
Based on numerous studies, the side effects associated with glucosamine are typically mild and often related to the digestive system. These adverse effects are not unique to Amway or Nutrilite products but are a general risk associated with glucosamine supplementation.
Common Gastrointestinal Side Effects
- Nausea: A common feeling of stomach unease, sometimes leading to vomiting.
- Heartburn: A burning sensation in the chest or throat.
- Diarrhea or Constipation: Glucosamine can affect bowel habits, causing either loose stools or difficulty passing stool.
- Indigestion: General stomach discomfort, often reduced by taking the supplement with food.
Less Common Side Effects
Some individuals may experience other, less frequent side effects.
- Headaches: Headaches have been reported by some users.
- Drowsiness: A feeling of sleepiness or fatigue can occur.
- Skin Reactions: Rashes or itching may manifest on the skin.
Important Warnings and Precautions
Certain individuals should exercise caution or avoid taking glucosamine due to specific health risks and potential contraindications. Amway's Nutrilite glucosamine, like other brands, includes advisories regarding these conditions.
Shellfish Allergy
Many glucosamine products, including Nutrilite's OsteGlucosamine, are derived from the shells of shellfish, such as shrimp, lobster, and crabs. Individuals with shellfish allergies are at risk for allergic reactions, which can range from mild skin rashes to more severe symptoms like swelling of the face, tongue, or throat, and difficulty breathing.
Diabetes and Blood Sugar
There has been a long-standing concern that glucosamine could affect blood sugar levels and insulin sensitivity, though research has produced mixed results. The manufacturer for Nutrilite OsteGlucosamine advises that diabetics who choose to use the supplement should monitor their blood glucose levels closely and may need to adjust their medication dosage under medical supervision.
Glaucoma
Some studies have indicated that glucosamine may increase the pressure inside the eye, which could worsen glaucoma. Individuals with glaucoma should consult a healthcare provider before starting or continuing glucosamine supplementation.
Blood Thinners (Warfarin)
Glucosamine can interact with anticoagulant medications like warfarin (Coumadin), potentially increasing its blood-thinning effect and raising the risk of bleeding and bruising. Taking glucosamine while on warfarin is not recommended.
Pregnancy and Breastfeeding
Due to insufficient research on the safety of glucosamine for this population, pregnant and breastfeeding women are advised to avoid its use. Nutrilite OsteGlucosamine specifically recommends that pregnant or nursing women consult a physician before use.
Asthma
In some cases, glucosamine has been reported to trigger or worsen asthma symptoms. People with asthma should be cautious and monitor their symptoms if they choose to take glucosamine.

Manufacturer Advisories for Nutrilite
Amway's Nutrilite OsteGlucosamine product contains specific advisories and precautions outlined on their Malaysian website. These are crucial for users to understand.
Nutrilite OsteGlucosamine Advisories
- Contains Shellfish: The product explicitly states it contains ingredients from shellfish (shrimp).
- Not for Vegetarians: Due to the gelatin (from beef) and shellfish content, it is not suitable for vegetarians.
- Consult a Physician: The manufacturer advises consultation with a physician for pregnant and nursing women, as well as individuals with medical conditions like diabetes or hypoglycemia.
- Dosage Limit: Consuming over 2000mg per day is not recommended, as extremely high levels can increase the risk of gastric issues.
How to Mitigate Side Effects
To minimize the risk of experiencing adverse effects from glucosamine:
- Take with Food: Taking the supplement with meals can help reduce stomach discomfort, nausea, and indigestion.
- Start with a Lower Dose: Gradually increasing the dosage can allow your body to adjust to the supplement.
- Be Aware of Allergies: Always check the source of glucosamine. If you have a shellfish allergy, you must find a shellfish-free product. Nutrilite is not suitable for this allergy.
- Stay Informed: For the latest information on supplements and their interactions, reliable resources like Examine.com are helpful.
Conclusion
While Amway's Nutrilite glucosamine is considered safe for most healthy adults, it is not without potential side effects, consistent with other glucosamine supplements. The most common are mild gastrointestinal issues, but more serious risks exist for specific populations. Critical warnings apply to individuals with shellfish allergies, diabetes, glaucoma, or those taking blood-thinning medication. For Nutrilite users, it is important to note the product's shellfish origin and consult a doctor, especially if you have pre-existing health conditions or are pregnant or breastfeeding.
