Some studies reported skin improvements from collagen supplements. But many of these studies were sponsored, fully or in part, by cosmetic or supplement companies<\/em><\/span><\/h4>\n

Celebrity testimonials abound for pills, potions and creams that purport to make you look younger.<\/span><\/p>\n

This time collagen supplements are in the spotlight, after Jennifer Aniston became the face of one wellness brand\u2019s collagen campaign in late 2020.<\/span><\/p>\n

While some research has found benefits of collagen supplementation for some aspects of skin health, it\u2019s a case of buyer beware. The evidence is generally weak, with many of the studies claiming to find positive effects from collagen supplementation funded mostly by industries that manufacture these products. Therefore, the results need to be interpreted with caution.<\/span><\/p>\n

When you\u2019re reading articles promoting these products, be especially wary of phrases such as \u201cwe may receive compensation for some links to products and services\u201d. These statements often mean the publication has negotiated some kind of payment for featuring products in its editorial coverage. Therefore, what you\u2019re reading isn\u2019t necessarily an independent evaluation of the product\u2019s effectiveness.<\/span><\/p>\n

Rather than spending a lot of money on collagen supplements that promise to defy signs of ageing, smooth wrinkles and renew your skin, spend it on healthy food. You will get better value in terms of your health and well-being in the long-term.<\/span><\/p>\n

What does the science say?<\/span><\/strong><\/p>\n

Normal ageing is associated with loss of connective tissues within the skin, leading to a reduction in elasticity and development of wrinkles and creases.<\/span><\/p>\n

A 2019 review of collagen supplements, conducted by US university researchers, found four of the five studies included had reported some degree of improvement in some skin variables.<\/span><\/p>\n

This included improvements in: skin moisture and collagen density; skin hydration, wrinkling and elasticity; skin elasticity but not moisture content; and skin moisture, elasticity, wrinkles and roughness.<\/span><\/p>\n

Across the studies, closer scrutiny of the methods by the reviewers found many were rated as being of low methodological quality. The reviewers flagged a number of limitations of the studies. These included that the supplements differed across the trials, as did the types of people included in the studies, meaning you can\u2019t compare results between trials.<\/span><\/p>\n

It also wasn\u2019t clear how the results translated to actual changes in skin appearance and whether this was noticeable to other people.<\/span><\/p>\n

Amino acids needed to make collagen can be found in other foods containing protein. There\u2019s no reliable evidence amino acids in collagen supplements speed up the process by which the body makes collagen.<\/span><\/p>\n

What\u2019s more, most of the studies were either fully or partly funded by cosmetic or supplement companies. This means the results of the research should be interpreted with caution, especially when the affiliation statement shows the study authors were also employed by the supplement manufacturer. Further high quality, independent research studies are needed.<\/span><\/p>\n

What is collagen and where does it come from?<\/span><\/strong><\/p>\n

Collagen is the major structural protein in skin and other connective tissues such as cartilage, bone, tendons and ligaments.<\/span><\/p>\n

It has a triple helix structure. Imagine three slinkies coiled around each other, and that\u2019s roughly what collagen looks like.<\/span><\/p>\n

The triple helix shape makes it very strong and flexible.<\/span><\/p>\n

Vitamin C is essential for the chemical pathway that makes collagen in the body. Without adequate vitamin C, the collagen would be unstable, meaning the coils would unfurl, and you would develop scurvy.<\/span><\/p>\n

Before you grab a bottle of collagen supplements, you may want to consider where it came from. Rich sources of collagen include pig skin, cattle hide, pork and cattle bones, tendons and cartilage, chicken cartilage and fish scales.<\/span><\/p>\n

A complete diet is better value for money<\/span><\/strong><\/p>\n

A 2019 survey reported 37% of Australians spent up to A$20 a month on cosmetics and personal care, with 26% spending between $21-50 and 15% spending $51-200 a month.<\/span><\/p>\n

A bottle of collagen supplements costs anywhere between roughly A$15-20 to over $100. Each capsule, or per serve, contains roughly between half a gram up to five grams of collagen.<\/span><\/p>\n

By comparison, you can get better value for money by eating foods rich in protein like meat, chicken, fish, eggs, milk, cheese, nuts, tofu, dried beans and legumes. This will provide the amino acids your body needs to make collagen.<\/span><\/p>\n

Because collagen would be unstable without vitamin C, it\u2019s also important to regularly eat foods rich in it. Good sources include broccoli, Brussels sprouts, capsicum, tomatoes, spinach, kiwifruit, lemons and oranges.<\/span><\/p>\n

Also aim to regularly eat foods rich in other nutrients needed to help keep skin healthy. This includes:<\/span><\/p>\n

    \n
  • zinc, which is found in seafood, meat, chicken, dried beans and nuts. Inadequate zinc intake can lead to skin conditions including acne and some types of dermatitis.<\/span><\/li>\n
  • vitamin A, from oily fish, egg yolks, cheese, tofu, nuts, seeds, whole grains and legumes. Vitamin A helps immature skin cells develop into a mature skin layer which forms the body\u2019s first layer of protection. \u201cBeta-carotene\u201d found in vegetables can be converted into vitamin A in the body. Good sources include pumpkin, carrots and leafy green vegetables.<\/span><\/li>\n
  • and foods rich in polyphenols. These are small chemicals found in vegetables, fruit, herbs and spices that help plants grow well or protect them from pathogens. Studies suggest higher intakes are associated with slowing some of the skin damage caused by exposure to the sun.<\/span><\/li>\n<\/ul>\n
