Are multivitamins just expensive pee or do they actually have benefits?
i've been tracking macros for a few years now, and I can't help but wonder if multivitamins are worth it or if I'm just flushing cash down the toilet (literally). The studies out there seem to be split; some suggest they provide minimal benefits for healthy individuals, while others claim they can fill gaps in our diets.
Let's dive into the science. A meta-analysis from 2013 (Mason et al.) showed that for most people who eat a well-balanced diet, multivitamins did little to reduce the risk of chronic diseases. Yet, another study from 2020 (Fortmann et al.) indicated that they could help certain populations, like older adults or those with specific dietary restrictions. But I can't help but wonder if it's just another marketing ploy or if there's real value.
Then there's the issue of absorption. Some ingredients in these multis can interfere with each other, like calcium and iron, so timing and formulation matter. I mean, if I'm taking a multivitamin just to pee out the excess, what's the point? And let's not even get started on the brands. Is it really necessary to shell out for high-end brands like Garden of Life, or is a cheap one from Costco just as effective?
So, r/supplements, are we wasting our time and money with these things or is there a case to be made for their inclusion in our regimens? What are your thoughts?
