Researchers tested the effects of a daily multivitamin on cognitive changes in a study of 573 participants with in-person visits in the COSMOS trial. The researchers also conducted a meta-analysis among over 5,000 non-overlapping participants across the three separate cognition studies within the COSMOS trial. Results showed a statistically significant benefit for cognition among participants taking the multi-vitamin compared to placebo, suggesting that a multi-vitamin could help prevent memory loss and slow cognitive aging among older adults.
There’s lots of studies out there all suggesting that multivitamins are simultaneously good and bad. My nutrition specialist made it clear to me that while multi-vitamins can replace things you’re missing out on, it’s better to have slightly not enough than too much of something and that it’s better to try to eat your vitamins in the way of food if possible. These days, the only vitamins I take are D in the winter and B12 if I haven’t eaten enough meat. I think the only time I make an exception is when I’m too sick to properly cook a nutritious meal and I feel I should replace those nutrients somehow.
Yeah we try to do the same, only eat required vitamins. We also eat magnesium, zinc, and fish oil.
What I do is take half a dose everyday. I take multivitamin gummies and the recommended 2x a day basically gets me 250% of certain vitamins. That’s too much especially since I get some of them naturally from what I eat. So I only take 1 gummy a day.
