One pill vs. many: Which fixes vitamin gaps faster?

Not medical advice. For informational purposes only. Always consult a healthcare professional. Terms
People getting ready for weight-loss surgery often have low vitamins. Some took one pill with all needed vitamins, others took many separate pills.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.

Taking dietary supplements restores missing micronutrients from inadequate food intake and maintains normal bodily functions.
Among obese adults with three or more micronutrient deficiencies, taking one daily bariatric-specific multivitamin led to a 25.2 percentage point higher rate of full correction of all deficiencies after four weeks compared to taking multiple separate supplements.
Among obese adults with multiple micronutrient deficiencies, those taking a bariatric-specific multivitamin followed their regimen 92% of the time, while those taking standard supplements followed theirs 70% of the time.
Obese adults with multiple micronutrient deficiencies who took a bariatric-specific multivitamin took one supplement per day on average, while those taking multiple targeted supplements took 3.5 per day.
In obese adults with three or more micronutrient deficiencies, taking a bariatric-specific multivitamin led to a higher proportion of deficiencies being corrected after four weeks than taking standard targeted supplements.
