Collagen is produced naturally, however as you age and other factors you may be exposed to can cause a dramatic drop in production. By the time the average human is 30, your production will reduce significantly. Other factors that can reduce your production include exposure to UV light, as well as smoking, and ozone. Taking a collagen supplement may have benefits such as a decrease in wrinkles, healthier hair, skin, and nails. Studies also show it may help with bones, cartilage, and tendons.
