The Science

How It Works

Understanding how The Power of Glucosamine supports your body's joint health through multiple pathways.

Cartilage Component Replenishment

Cartilage Component Replenishment

Cartilage naturally contains specific structural components:

  • Type II Collagen makes up approximately 75% of cartilage
  • Proteoglycan comprises about 15%
  • Hyaluronic Acid accounts for roughly 5%

Research shows these components decrease with age, starting from your 20s. This formula provides these key components in a concentrated daily dose of just 2 tablets.
Triple-Action Support System

Triple-Action Support System

The formula addresses joint health through three key mechanisms:

  • Cartilage structure support via Glucosamine, Proteoglycan, and Type II Collagen
  • Joint lubrication support via Hyaluronic Acid
  • Muscle support via Imidazole Peptide

This comprehensive approach recognizes that smooth movement depends on healthy cartilage, adequate joint fluid, and supporting muscles working together.
Balanced Botanical & Nutritional Support

Balanced Botanical & Nutritional Support

Beyond core cartilage ingredients:

  • Hokkaido Oitadori (traditional Japanese plant)
  • White Willow extract
  • Coix seed (Hatomugi)
  • Complete B-vitamin complex

These ingredients have been used traditionally in Japan and provide additional nutritional support for daily health and mobility.
