Personally, I buy protein powder even though I know the ingredients are actually too cheap to justify the price. But I’m too lazy, and the reward of a cold chocolate shake after working out makes me forget about the outrageous cost. It’s a little guilty pleasure I’ve come to terms with.
We get collagen powder but its not very expensive. I mean we splurge on things but im not sure if they are overpriced really. Like pastuer raised eggs. They are like twice as expensive but they are meaningfully better. Hopefully health wise but definately in taste. Same with natural low ingredient ice cream. Id just rather eat them less often than eat the crappier stuff. There is likely something but I can’t think of it. My wife buys a lot of keto type stuff and I feel thats overpriced but I don’t value them higher than normal products whereas she does.
