Collagen-X by Chemistry Natural Science is a thoughtfully formulated multi-collagen supplement crafted for South African women and men who want comprehensive collagen support — not just for skin, but for joints, connective tissue, and long-term mobility too. Combining bovine (Type I & III), undenatured chicken (Type II), egg membrane (Type X), and hyaluronic acid, it delivers the full spectrum of collagen types your body needs as natural production declines.
