Product overview
Chondroitin ZS Tablets are a Class 3 OTC medicine manufactured and sold by Zeria Pharmaceutical. For more than 60 years since its launch in 1964, it has been a trusted medicine used by people troubled by joint pain, lower back pain, and similar concerns.
It contains 1,560 mg of the active ingredient sodium chondroitin sulfate ester per daily dose—the highest amount among OTC medicines, and the only one at this level. By helping replenish a building block of cartilage, it is recognized for 7 indications, including joint pain, lower back pain, frozen shoulder, and neuralgia.
One factor in knee and lower back pain—decline of cartilage
When cartilage components decrease due to aging or physical stress from exercise, bones are more likely to rub against each other, making joint inflammation and pain more likely. The active ingredient in Chondroitin ZS Tablets, “sodium chondroitin sulfate ester,” is a major component of cartilage and approaches pain from within.
