Collagen supplements have gained popularity in the last decade touting benefits to skin, hair, and nail health. You'll also see brands claim their collagen supplements promote joint health, enable muscle growth, and may even encourage gut health, too. With the possibility of so many positive outcomes, many have incorporated this daily supplement into their routine. You'll most often find collagen in powdered form, but pre-made drinks exist as well as capsules.

Your body produces collagen, although, with age, this production tends to slow. Lifestyle factors may also reduce your production of collagen, including excess exposure to the sun, lack of sleep, and nicotine and alcohol use. Collagen is a protein source and accounts for about 30% of the protein within your body. It provides structure to skin, bones, and connective tissues, which is why it may be able to benefit so many different areas of the body. You'll only find collagen in animal products, but plants contain nutrients that may boost your body's ability to produce its own collagen. For example, vitamin C is found in many fruits and vegetables and may be able to increase collagen synthesis.

Eating animal meat is one way to introduce collagen into your diet, but supplemental collagen is a much more concentrated form that will deliver your body more collagen for fewer calories. Certain foods, like bone broth, are also known for their collagen content and can be incorporated into your diet.

If you are considering adding a collagen supplement to your regimen, here are the 8 best collagen supplements.
