Collagen is the most abundant structural protein in the body, supporting skin elasticity, joint cartilage, bone density, and connective tissue throughout life. Production naturally declines from the mid-twenties onward, which is why collagen supplements have become one of the most widely used daily nutrients among adults in Ireland. The range here spans hydrolysed collagen powders, marine collagen capsules, and multi-ingredient formulas that combine collagen peptides with vitamin C, hyaluronic acid, or biotin. Hydrolysed forms are broken into shorter peptide chains for easier absorption, making them the most researched format in this category. Marine collagen, sourced from fish, is favoured for skin-focused use, while bovine collagen is more commonly chosen to support joints and gut lining. Choosing the right supplement depends on your primary goal. Skin and hair concerns are well served by marine collagen type I, while type II collagen is more relevant for cartilage and joint mobility. Look for products with a clear collagen peptide concentration per serving rather than proprietary blends. All supplements in this carefully selected range come from trusted brands, chosen for quality and formulation transparency.
