Most people believe that collagen is the most essential and best type of collagen.
But in a new study, researchers from the National Institutes of Health (NIH) and the University of Michigan have found that collagen type 2 is just as important.
“We wanted to look at the question of whether people really need a particular type of non-collagen supplement to make their skin healthy,” said lead author Dr. Matthew Pugh, a dermatologist at the National University of Singapore (NUS).
“What we found was that most people did need collagen type 1 and type 2 to get a healthy skin.”
In the new study published in the Journal of Cosmetic Dermatology, Pugh and his colleagues recruited more than 2,500 people to take a collagen test.
“The results showed that people who took collagen supplement products that were in the best collagen type were more likely to have a healthy, well-formed skin,” Pugh said.
The researchers then looked at the results of another set of participants.
They were also able to measure how well the participants were able to control the levels of other common allergens that could cause allergic reactions.
“Collagen is an essential component of skin and therefore, if you are not getting enough of it, your skin will not look as well,” Puddles said.
“And then you also need to consider the other allergens, like the other things that people can get from eating too much refined sugars, as well as the chemicals that come out of processed foods.”
Pugh and colleagues found that people with a high level of collagen were more than twice as likely to be able to use the products containing collagen type 3 and 4, and more than three times as likely as those with a low level of the protein-rich type.
“That suggests that people need to take the collagen type in a very specific way,” he said.
Pugh said he and his team hope their findings will be useful to people considering supplementing their diet.
“It’s really important that people get enough of the collagen types they need,” he added.
“You need collagen that’s more efficient at creating a better skin, a more hydrated skin, and a more healthy skin.
And that’s where you can find a lot of collagen in your diet.”
