Unfortunately, there’s no way to know for sure that the oral collagen supplements we take actually support any of these functions because the body breaks down collagen proteins during digestion. For those interested in finding proven alternatives to boost skin’s natural collagen production levels, consider revamping your skin care routine into a more holistic one. In addition to your topical anti-aging skin care regimen and daily SPF application, consider what goes into your body as well: limit your intake of alcohol and cut out smoking  alongside a focus on a healthier diet complete with nutritious sources of fatty and amino acids, such as avocados and fish. These steps will help to prevent any further breakdown of collagen while supporting skin health.
