Cartilage supplements come from animal sources like bovine, shark, or chicken. Common forms include UC-II (a patented type II collagen), shark cartilage, and bovine tracheal cartilage. People take them to support joint comfort and mobility.
Most cartilage supplements are capsules. Taking them with a meal may improve absorption. Dosing varies by product. For UC-II, many people take it once daily, either with food or on an empty stomach, as the brand instructs.
Key cautions: Shark cartilage contains fish and can trigger reactions in those with fish allergies. Pregnant or nursing women should consult a doctor before using any cartilage product. Quality and sourcing differ, so choose reputable brands.
