The USPSTF tasked researchers with updating the data on vitamin supplementation with two important outcomes in mind: cancer and cardiovascular death. Why vitamins? Because the observational data are clear and compelling. People with vitamin deficiencies are at higher risk for these bad outcomes.

They are just stating that vitamins dont help with cancer and cardiovascular death? But you’re saying that the research shows that all vitamins are worthless?

Ive used vitamins for minor things, like Vitamin D and Calcium which do make my nails grow and become thick. I’ve also used hair vitamins and noticed faster hair growth and lots of baby hairs.
