New study on collagen gummies - legit or bias?

I'd be skeptical too. Most of these studies are small or sponsored. But I've tried collagen gummies myself and my nails got stronger. Taste-wise, the berry ones are pretty good, but the texture can be chewy. Anyone else?

Look at the sample size and funding. If it's from a supplement company, it's probably biased. I'd check for independent replication. Also, if they used a specific brand, that's a red flag. My smartwatch can't track skin elasticity, so I'd say take it with a grain of salt.
