Study pls? Actually could you just give a citation? Just kidding idgaf will take your word for it lol.
Is there causation or correlation here? Perhaps the same group who are looking for an easy quick fix with multivitamins are unlikely to put in the time/effort to maintain a balanced diet and active lifestyle. Maybe multi vitamins aren’t effective enough to be an unhealthy lifestyle?
Group taking/selecting individual vitamins may be more conscious of their health, knowledgeable of their needs/defiencies and motivated to address or improve it. In much the same way wouldn’t this group be likelier to watch their diet and maintain an exercise regimen?
Maybe I’m talking out my arse here but isn’t saying multis are not beneficial based on this is a bit of a leap?
I can relate tho. My mum has $100s worth of vitamins and minerals but no gym membership or activity/exercise for that matter.
