Social media often paints a picture where supplements seem like miracle solutions for almost every issue. Yet, a deeper dive into the research reveals that most of these products fall short. Collagen supplements, however, stand out as a potential exception, with growing interest and studies indicating they might enhance skin elasticity.
Previously, we viewed collagen supplements as nothing more than overpriced protein powder due to insufficient evidence supporting their benefits. However, with newer studies emerging and increased attention, we decided it was time to re-examine their potential.
Key insights into collagen supplements and their clinical trial results
Several clinical trials indicate that collagen supplements may enhance skin elasticity and hydration. These trials often involve placebo-controlled designs, where participants remain unaware of whether they received the supplement or a placebo until the study concludes.
This type of study design helps minimize unconscious bias. Despite our best efforts to remain objective, the desire for a particular outcome can subtly influence perceptions and results.
As Michelle Wong, a cosmetic chemist known for debunking beauty myths on Instagram, pointed out in an email to Mytour, “Many of these clinical trials are funded by supplement companies, which raises concerns about potential bias.”
Current theories on how collagen might function
My skepticism toward collagen supplements stems from the fact that, like all proteins, they are broken down into amino acids during digestion. The idea that consuming collagen will directly benefit your skin seems scientifically implausible.
However, consuming collagen might still have an impact through other mechanisms. As Wong notes, collagen is rich in hydroxyproline, an amino acid exclusive to collagen and absent in other dietary proteins.
A leading theory suggests that hydroxyproline could act as a signal, prompting the body to boost collagen production and reduce its breakdown. This mechanism, at the very least, offers a more plausible explanation.
Is taking a collagen supplement worth it?
There’s often a significant gap between clinical trials and everyday use. For collagen supplements, the product used in studies may differ greatly from what’s available on store shelves.
As Wong clarifies, “Collagen supplements undergo various hydrolysis methods, breaking down the collagen differently. This results in unique peptide compositions in each product.”
Considering everything, is it worthwhile to take collagen supplements? Given their high cost, the potential benefits might not justify the expense. If your goal is to improve your skin, focusing on proven methods like consistent sunscreen use and retinoid application might be a more economical and effective choice.
Ultimately, our position remains that collagen supplements are essentially overpriced protein powder—though there is slightly more evidence now suggesting some additional benefits.
