How It Works
How It Works
Glucosamine sulfate provides the building blocks your body uses for cartilage repair, while chondroitin sulfate helps maintain cartilage structure and joint lubrication. The sulfur component in both compounds supports connective tissue health.
Who It's For
Adults experiencing joint stiffness, athletes putting stress on their joints, and active individuals wanting to maintain mobility as they age.
Who It's Not For
Those with shellfish allergies should avoid due to the glucosamine source from shrimp/crab exoskeleton.
About This Product
What It Does
This natural health product helps reduce joint pain and supports cartilage repair for better mobility. Clinical studies show glucosamine sulfate may stimulate joint repair processes, while chondroitin sulfate maintains the three key functions that keep cartilage healthy.
Why It Works
- GLUCOSAMINE SULFATE: Unlike glucosamine HCl, the sulfate form provides the sulfur your joints actually need for repair — fully reacted and bioavailable at 500mg per capsule.
- CHONDROITIN SULFATE: Naturally found in cartilage where it maintains structure, supports lubrication, and helps with shock absorption.
- COMBINED FORMULA: Both nutrients work together — glucosamine provides building blocks while chondroitin maintains the matrix.
What's Inside
Clean formula with no artificial fillers. Contains ingredients sourced from shrimp/crab exoskeleton and bovine cartilage. NPN N/A.
Why we carry it: Natural Factors delivers clinical-strength doses of both nutrients in one convenient formula — no guesswork.
