Overview
NOW Supplements UC-II Advanced Joint Relief is a 60-capsule vegetarian formula combining undenatured type II collagen with hyaluronic acid, boron and vitamin D-3 for bone and joint support.
Undenatured type II collagen (UC-II) is processed to keep its molecular structure intact, unlike the more common hydrolyzed collagen, and that distinction is what buyers in this niche tend to compare first. Rounding it out with hyaluronic acid, boron and vitamin D-3 puts several joint-support ingredients into a single capsule instead of separate bottles.
- Undenatured type II collagen (UC-II)
- Adds hyaluronic acid, boron and vitamin D-3
- 60 vegetarian capsules
- Allergen-free formula
Who it's for
Suited to adults building a joint-support routine who want undenatured type II collagen specifically rather than the more common hydrolyzed form. The vegetarian capsule shell suits those avoiding gelatin softgels.
