The Claim
Some believe that chondroitin only works if used over a long period, suggesting it takes months or longer to see any benefits.
Origin
This belief likely stems from early studies and anecdotal experiences highlighting delayed onset of symptom relief.
What Science Says
Clinical studies, including RCTs, show that chondroitin may indeed take several weeks to months to exhibit notable effects. However, benefits can sometimes be seen in a shorter timeframe depending on the individual and dosage. Long-term use is often recommended for sustained benefits, but not exclusively for effectiveness.
Verdict
Partially True
