Turns Out Collagen’s Glow-Up Might Be a Funding Effect
By Mark J Kaylor
Turns out the biggest predictor of whether a collagen study finds benefits isn’t the dose, the participants, or the collagen itself. It’s who paid for the research.
A 2025 meta-analysis pooling 23 randomized trials and nearly 1,500 participants found collagen supplements improved skin hydration, elasticity, and wrinkles. Headline finding, case closed, right? Except when researchers split the studies by funding source, the effect vanished in independently funded trials and held up in industry-funded ones. Same molecule, same skin, wildly different results depending on who signed the check.
Study quality told the same story: rigorous trials found nothing, looser ones found glowing results.
None of this proves collagen does nothing. It proves “23 studies agree” means a lot less than it sounds like if you don’t ask who ran them.
Next time a label cites “clinical studies,” skip the question of how many. Ask who paid for them.
