Whatever room you’re in, anytime, anywhere, with anyone, what is always the most popular protein in the room? No, it’s not beef. Not chicken either. Nope, not even eggs. It’s collagen. Collagen is the most abundant protein in your body, a building block for muscles, skin, bones, tendons, and cartilage; basically, it helps hold our bodies together. So yeah, I’d say it’s the most popular protein in the room. And since the 2010’s, more people have been asking, “do we need to consume collagen? Will it keep us looking younger and moving better even if we don’t need to consume it?”
But as we know, online popularity doesn’t necessarily reflect real life, so do these collagen creams, pills, and powders back up their popularity?
Most scientific studies have focused on skin and joint health and have found collagen supplements to improve skin elasticity, joint mobility, and joint pain. However, many of these studies are small, are not human studies, and have been found to be partially or fully funded by related industries that would benefit from the sale of collagen supplements. Overall, there is a lack of a developed body of research with large, human-subject, and unbiased randomized controlled trials. In addition, the dietary supplement industry is not regulated by the Food and Drug Administration, meaning supplements aren’t verified that they contain what they say they do or that they’re free of contaminants such as heavy metals, bacteria or pesticides. A 2020 analysis of 28 collagen supplements by the Clean Label Project found that 64% had detectable levels of arsenic, one third for lead, and 17% for cadmium.
We also still don’t know if the collagen from supplements gets used for collagen in our bodies. Everything we consume is broken down to its basic components in order to be absorbed and then those components are built back up for whatever is needed most at that time. Since there are hundreds of different proteins used in all kinds of processes in our bodies, it’s difficult to say that the amino acids from the collagen in a supplement will all stick together and be built back up into only collagen in our bodies.
So what about maybe collagen in food?
A balanced diet not only provides the basic ingredients for our own collagen production, but it also guarantees that we’re eating antioxidants, which are compounds that fight the oxidative stress that degrades collagen and are found in fruits, vegetables, nuts and seeds.

Okay, so what’s the final opinion on popularity?
It’s Regina George-esque. While collagen supplements may not directly be harmful, research on whether they’re effective is lacking, regulation on ingredients and efficacy are absent, and it’s still unclear how our bodies are actually using them after we consume them. However, other factors, such as eating a balanced diet, are proven to support natural collagen production, along with providing multiple other benefits, and therefore, may be better ways to spend your money. Just because collagen supplements are popular, doesn’t mean you should ditch the friends that have stayed by your side this whole time for them.
