As we age, the amount of collagen in our body decreases. By age 25, collagen levels decrease at a rate of 1.5% a year. By age 40, collagen is depleted faster than it is produced! And by age 60, over half of the body’s collagen has been depleted. At this stage, we are left with achy joints, sore muscles, wrinkly skin, and brittle bones. Collagen supplements repair joints and connective tissue; treat osteoarthritis, rheumatoid arthritis, and osteoporosis; improve hair quality, skin elasticity, and sleep; shorten recovery after exercise; calm anxiety; help heal digestive problems; and can even help you lose weight!
