The Claim

In healthy men aged 55–65, 16 weeks of multivitamin supplementation significantly reduces LDL cholesterol and improves the LDL/HDL ratio, while no such effect is observed in women.

Cause and effect
1 study reviewed
In plain English

In healthy men aged 55–65, taking a multivitamin daily for 16 weeks lowers LDL cholesterol and improves the ratio of LDL to HDL cholesterol. These changes do not occur in women taking the same supplement.

See the scientific wording

In healthy men aged 55–65, 16 weeks of multivitamin supplementation significantly reduces LDL cholesterol and improves the LDL/HDL ratio, indicating a causal beneficial effect on lipid profile, while no such effect is observed in women.

Why this might work

In men, plant compounds in the multivitamin increase the liver's ability to remove bad cholesterol from the blood, while also reducing damage from harmful molecules, which together lower bad cholesterol and improve the ratio of bad to good cholesterol.

  1. Study: Improved Blood Biomarkers but No Cognitive Effects from 16 Weeks of Multivitamin Supplementation in Healthy Older Adults

    In a study where older men and women took daily multivitamins for 16 weeks, only the men saw better cholesterol numbers—lower bad cholesterol and a healthier ratio—while women didn’t. So yes, the study supports the claim.
