You might be surprised to learn that you don’t need a huge dose of collagen each day to reap the benefits for skin health and anti-aging.
While the body naturally produces collagen, levels naturally start to decline by around age 30, so taking exogenous collagen may help combat this loss and smooth your skin.
One study found that dosages as low as 2.5 to 5 grams per day for 4 weeks were successful in increasing skin elasticity in elderly women.
Another study concluded that 10 grams of collagen peptides taken as part of a fruit-based beverage were significantly more successful in decreasing the depth of existing skin wrinkles in middle-aged women compared to placebo after only 9 weeks.
