Two out of three users (66.25%) perceived taking MVM as being beneficial for normal immune functioning. A slightly lower number (63.25%) felt that supplementation gave them confidence in maintaining their overall health, and more than half (59.75%) believed that their metabolism had improved.
The findings came from an online questionnaire involving 400 consumers between the ages 35 and 60 in Taiwan who used Haleon’s Centrum Advance or Centrum Silver men’s and women’s supplements at least three times weekly in the three months prior to completing the survey. Individuals who used other supplement brands were excluded from the study.
Over half (59.25%) of the respondents were daily users of MVM supplements, while 40.75% were occasional users who took supplements between three and five days per week.
Writing in the Journal of Health, Population, and Nutrition, the research paper authors from Haleon, IQVIA Solutions and WNS Global Services highlighted that the findings reflected real-world patterns of MVM supplement use, helping to connect evidence from controlled trials with everyday consumer behavior.
“Real-world evidence bridges the gap between controlled trial outcomes and actual consumer experiences, offering valuable insights into product utility,” they wrote, adding that since the survey respondents bought and used MVM supplements on their own without any third-party intervention or prescription, the results can be considered “neutral and unbiased.”
What were the perceived benefits?
Findings showed that most respondents perceived that taking supplements had improved their immunity, metabolism and overall health.
Using the Immune Status Questionnaire (ISQ), 66.25% reported having a normal immune functioning after taking MVM.
The ISQ measures perceived immunity status on a scale of 10 based on the frequency of immune-related complaints experienced, including sudden high fever, diarrhea, headache, common cold and coughing. An ISQ score of six and above indicates perceived normal immune functioning, while a score of below six indicates reduced immune functioning.
According to the survey, 67% strongly agreed or agreed that their body defense had improved while taking MVM supplements.
Regarding metabolism, 59.75% of respondents either strongly agreed or agreed that it had improved with MVM supplements. Notably, the perceived benefit for metabolic health was higher among men (65.17%) than in women (54.27%).
As for overall health, 63.25% either strongly agreed or agreed that taking just one MVM pill daily gave them the confidence to maintain overall health.
Other commonly perceived benefits
The other commonly perceived benefits of MVM intake included better skin complexion and energy support.
Nearly two in three (59%) strongly agreed or agreed that MVM intake gave them energy to better perform everyday tasks and half (50.50%) reported having more energy for sports and training.
Of the 53.25% who reported improved overall skin complexion, 38% perceived that their skin looked “better”, and 36.25% perceived that their skin looked “healthier” when taking MVM supplements. Individuals aged 50 and above were also more likely to perceive MVM as beneficial for skin than those under the age of 50 (60.14% vs 49.42%).
Sleep and mental alertness were also assessed. More than half of respondents (57.50%) strongly agreed or agreed that they woke up feeling more energetic, while 45.75% strongly agreed or agreed an improved ability to focus on daily tasks with MVM use.
Overall, users’ perception of MVM was positive, with over 70% expressing satisfaction, trust and a willingness to repurchase.
Top 10 reasons for taking MVM
Nutritional support was the most commonly cited reason for supplement use, reported by 68.25% of the respondents. This was followed by immune support (60.25%), overall health support (55.25%), improving physical health (43.25%) and maintaining foundational body health (43%).
Improving metabolism ranked sixth (31.75%), ahead of increasing energy levels (28.25%). Fewer respondents reported using supplements to improve sleep quality or help with falling asleep (21.75%), improve work performance (19.50%) or cope with stress (16.50%).
