Core Active Ingredients in Amway Glucosamine
The composition of Amway's glucosamine supplements under the Nutrilite brand varies by product and regional formulation. The primary active component is almost always a form of glucosamine, and other ingredients are added to provide a more comprehensive joint support formula.
Glucosamine Hydrochloride (HCl)
Most Nutrilite glucosamine products utilize Glucosamine Hydrochloride (HCl). This glucosamine is typically sourced from crustacean exoskeletons, such as shrimp and crab shells. Amway states the HCl form offers more active glucosamine per weight compared to the sulfate version.
Chondroitin Sulfate
Some formulas, like Nutrilite Joint Health in the US and Canada, include chondroitin sulfate. Often sourced from shark cartilage, chondroitin is a natural component of cartilage that may help attract fluid, providing joint cushioning.
OptiMSM™ (Methylsulfonylmethane)
Found in select advanced formulas like Nutrilite Joint Health, MSM is a sulfur-containing compound. It is included for its potential role in supporting healthy connective tissues.
Supporting Phytonutrients and Plant Extracts
Amway incorporates various plant-based ingredients for added nutritional benefits.
Boswellia Serrata Extract
Boswellia, an Indian herb, is a key ingredient in formulas like Glucosamine with Boswellia. Known for supporting joint health and flexibility, some products use a standardized extract like 5-LOXIN®.
Acerola Cherry Concentrate
This Nutrilite-exclusive ingredient is included as a natural source of Vitamin C. Vitamin C is important for collagen formation, which is vital for cartilage function.
Citrus Bioflavonoids
Concentrates from citrus fruits are included to provide plant phytonutrients.
Bromelain
Derived from pineapple, this enzyme is included in certain formulations to support normal joint function.
Inactive and Manufacturing Ingredients
Inactive ingredients are used to ensure proper form and stability.
- Stabilizers: Microcrystalline cellulose is commonly used.
- Flowing/Anti-Caking Agents: Magnesium stearate and silicon dioxide help prevent clumping.
- Capsule Material: Gelatin is often used, with the source varying regionally.
- Bulking Agent: Maltodextrin may be used as a filler.

Potential Considerations for Amway Glucosamine
Consider these points before taking Amway glucosamine.
Shellfish Allergy
Avoid these products if you have a shellfish allergy, as the glucosamine is derived from crustaceans.
Medical Conditions
Consult a physician if you have:
- Diabetes: Monitor blood sugar closely as glucosamine may affect glucose tolerance.
- Anticoagulants: Glucosamine can increase bleeding risk with warfarin.
- Pregnancy/Nursing: Consult a healthcare professional due to lack of safety data.
Effectiveness
Clinical evidence for glucosamine and chondroitin effectiveness is mixed, with some studies suggesting little benefit for conditions like knee osteoarthritis.
Conclusion
Amway's glucosamine products primarily use glucosamine hydrochloride from shellfish, but formulations vary. Many include Boswellia, Acerola concentrate, and citrus bioflavonoids. Advanced options like Nutrilite Joint Health add chondroitin sulfate, MSM, and hyaluronic acid. Always check the specific product label, especially for shellfish allergies or existing health conditions. Consulting a healthcare professional before starting any new supplement is advised.
