"Backed by 40 years of nutritional science"
Centrum is one of the most-studied multivitamin brands. The Physicians' Health Study II (14,000 male doctors, 11 years) found Centrum modestly reduced cancer risk but had no effect on heart disease.

"Antioxidants like vitamins C, E, and zinc support immune function"
Zinc at 11mg and Vitamin C at 90mg are at RDA levels — solid baseline doses with genuine immune support evidence.

"Multivitamins support energy and immune health for all adults"
For adults eating a varied diet, multivitamin supplements show no significant reduction in mortality, cancer, or cardiovascular disease.
USPSTF Vitamin Supplementation Recommendation, 2022 -
"Vitamin D supports healthy bones and immune function"
Centrum Adults provides only 400 IU of Vitamin D. Most adults need 1000-2000 IU daily to maintain adequate blood levels.
Consumer advice
If you eat a varied diet with plenty of vegetables, lean protein, and whole grains, a daily multivitamin probably won't move the needle much for you. But if your diet is inconsistent, you're vegetarian/vegan, or you're older and absorb nutrients less efficiently, Centrum Adults is a reasonable, affordable safety net. Buy it at Costco or a warehouse club — you'll pay a fraction of the per-tablet cost. Don't pay full retail when the identical formula is available for pennies per tablet in bulk.
