While collagen supplements may have once been considered a trendy niche—it’s now become a true staple in wellness and beauty routines all over the world. In fact, the collagen supplement market doubled from 2019 to 2022 and is projected to grow at over 6.5% annually in North America from now until 2032, according to data published in the American Journal of Medicine. And, that makes a lot of sense, considering these supplements aim to help replenish the stores of collagen that inevitably begin to decline as we age—plus, they may support healthier hair, skin, nails, and even joint health.
