10 things to note when buying these supplements for skin and hair

Collagen usually comes from animals, and the source impacts how your body absorbs it. Marine collagen, from fish, is known for its quick absorption and skin-friendly benefits. Bovine collagen, from cows, contains both Type I and III, making it great for skin, hair, and nails. Porcine (pig-based) is also common. If you’re vegetarian or allergic to fish, always check the label. Also, beware of brands claiming “plant-based collagen”—plants do not contain collagen. They might support your body’s collagen production, but they don’t provide the actual protein.
