I recommend it❣️
Verified Purchase
The quality is good. The ingredients and formula are free of unnecessary additives. Collagen is essential for health, that's a fact. Age, approximately 30-35, varies from person to person. The packaging is small, lasting for a month, but it's perfect for a trial. Benefits, improvements, and results will come with regular use, and only with C and hyaluronic acid. My knee still hurts. No diet is required. Deficiencies do occur, especially after age 35. You can substitute 400 ml of bone broth daily.

Noticeable Joint Comfort with Long-Term Use!
Verified Purchase
I’ve been taking Youtheory Joint Complex with UC-II regularly, and I’m very satisfied with the overall quality of this product. The ingredients are well selected and clearly focused on joint support. The tablet size is acceptable and easy to take with food, and the dosage is convenient for daily use. The main benefits I’ve noticed are improved joint comfort and flexibility. After a few weeks, morning stiffness became much less noticeable, and my joints feel more stable during movement and daily activities. I also feel that recovery after physical load is faster, which makes a real difference in everyday life. This supplement fits perfectly into my routine, and I plan to continue using it long-term.

This is my first time ordering from iHerb, but I've tried their products before and they're good, especially the retinol, it's amazing! I loved it so much. I also tried the magnesium and iron.

Pay attention to joint health
Verified Purchase
As we age, our body functions deteriorate. Knee joint problems are particularly noticeable. It's difficult to get enough in your daily diet to improve joint function. This product contains natural anti-inflammatory ingredients that strengthen and repair joint pain, so it's worth a try.
