B-2Cool® (Undenatured Type II Collagen)

Evidence Level
Moderate
1 Clinical Trial
3 Documented Benefits
3/5 Evidence Score

B-2Cool® supplies undenatured (native) type II collagen, a low-dose joint ingredient that works differently from regular collagen. Rather than acting as a building block, a tiny daily dose is thought to retrain the immune system to stop attacking joint cartilage, and clinical research supports its use for knee comfort and flexibility.

Studied Dose About 40 mg of undenatured type II collagen per day.
Active Compound Undenatured (native) type II collagen, providing intact collagen with preserved three-dimensional structure.

Benefits

Knee comfort

In a multicenter randomized controlled trial, undenatured type II collagen improved knee osteoarthritis symptoms versus placebo, supporting its joint-comfort use.

Supported by Trial 1

Joint flexibility and mobility

Undenatured type II collagen is studied for improving joint flexibility and range of motion, including in active people without diagnosed arthritis.

Supported by Trial 1

Low-dose convenience

A single small 40 mg daily dose works through an immune mechanism, far less than the grams needed for structural collagen.

Supported by Trial 1

Mechanism of action

1

Oral tolerance

Tiny amounts of intact type II collagen interact with immune tissue in the gut, training regulatory immune cells to reduce the inflammatory attack on joint cartilage.

2

Reduced cartilage inflammation

By calming the autoimmune component of joint wear, undenatured collagen helps preserve cartilage and ease discomfort.
