A quiet revolution in blood pressure management is taking place, and it involves something as simple as a daily multivitamin. But here's the catch: it's not a universal solution, and that's what makes it intriguing.
Researchers from Mass General Brigham have discovered that long-term multivitamin use can lower blood pressure and reduce hypertension risk for specific groups of older adults. This finding, published in the American Journal of Hypertension, is based on a secondary analysis of data from the COSMOS trial.
When examining the entire participant group, there were no significant differences in hypertension risk or blood pressure between those taking multivitamins and those on a placebo. However, the study revealed intriguing insights when focusing on specific subgroups.
The Power of Multivitamins for Certain Diets
For individuals with lower diet quality, as assessed by the Alternative Healthy Eating Index (AHEI) and Alternate Mediterranean Diet (aMED), multivitamin use was linked to a reduced risk of hypertension. This suggests that multivitamins may play a supportive role in improving nutritional intake and, consequently, blood pressure control.
Blood Pressure Benefits for Normal BP Starters
Additionally, among participants with normal blood pressure at the study's onset, taking a daily multivitamin led to small but significant reductions in blood pressure measurements over two years.
A Tailored Approach to Blood Pressure Management
Dr. Rikuta Hamaya, a corresponding author, emphasizes the importance of nutrition in blood pressure control, stating, "A daily multivitamin might be useful for reducing hypertension risk in people with poorer nutritional intake."
Dr. Howard Sesso, another corresponding author, adds, "Our findings suggest a daily multivitamin may not be a blanket solution but could be beneficial for specific older adult subsets."
The COSMOS Trial: Unraveling the Effects of Supplements
COSMOS, a randomized, placebo-controlled trial, examined the health impacts of cocoa extract and multivitamin supplements on older U.S. adults. For this analysis, researchers focused on 8,905 participants without hypertension at baseline, randomly assigned to take either Centrum Silver or a placebo daily, with a median follow-up of 3.4 years.
The study also tracked blood pressure changes over two years in two additional groups, with BP measurements taken either in a clinic or at home.
The Need for Further Exploration
The authors emphasize the need for additional studies to assess how daily multivitamins might affect blood pressure in younger and middle-aged adults and in different populations based on nutritional status.
Research Team, Disclosures, and Funding
The Mass General Brigham research team included Sidong Li, Jessica Lau, Pamela M. Rist, JoAnn E. Manson, and others. Sesso and Manson received investigator-initiated grants from Mars Edge, a Mars Incorporated segment focused on nutrition research and products, which provided infrastructure support and donated study pills and packaging. Pfizer Consumer Healthcare (now Haleon) also donated study pills and packaging.
Sesso additionally reported grants from Haleon and Pure Encapsulations, as well as honoraria and travel support for lectures during the study. Bernhard Haring, an author, reported lecture fees from Pfizer and other companies unrelated to the study.
The COSMOS trial received support from Mars Edge, Pfizer Consumer Healthcare (Haleon), and grants from the National Institutes of Health. Neither Mars Edge nor Haleon had any role in trial design, conduct, data analysis, or manuscript preparation/review.
And this is the part most people miss...
While multivitamins show promise for certain groups, they are not a standalone solution for blood pressure management. A healthy diet and lifestyle remain crucial. What do you think? Could multivitamins be a game-changer for some, or is this just a small piece of a larger puzzle? Share your thoughts in the comments!
