Vitamin D3 (2000 IU) and Vitamin K2 (200 mcg) are the gold standard pairing for bone health. D3 optimises calcium absorption from food, while K2 activates osteocalcin, the protein that binds calcium directly into bone matrix. Without K2, calcium absorbed through D3 can accumulate in arteries rather than bones. Together they form the most evidence-backed nutritional duo for long-term skeletal integrity.

Collagen is the primary structural protein in cartilage, tendons, and ligaments, and these three ingredients directly support its production: Glycine (300 mg) is collagen's most abundant amino acid; MSM (300 mg) provides the sulphur essential for connective tissue synthesis and reduces joint inflammation; Vitamin C (250 mg) is the critical cofactor that enables collagen cross-linking, maintaining the tensile strength of joints and cartilage.

Magnesium (450 mg) is the overlooked bone mineral; over 60% of the body's magnesium is stored in bone, where it directly influences bone density and crystal structure. Zinc (10mg) supports bone-forming osteoblast activity and inhibits bone breakdown. Copper (1,1 mg)  is essential for collagen cross-linking and the formation of strong connective tissue, working synergistically with Zinc for optimal structural support.

Chronic inflammation accelerates cartilage degradation and bone loss. Pterostilbene (50 mg) and Resveratrol (50 mg) are potent anti-inflammatory compounds shown in studies to inhibit inflammatory pathways that drive joint deterioration. Hyaluronic Acid (100 mg) supports synovial fluid, the natural lubricant that cushions joints and reduces friction. Methylfolate (276 mg) supports bone cell DNA synthesis, essential for healthy bone remodelling and repair.
