What this trial studies

This randomized, double-blind, placebo-controlled trial will give eligible midlife Asian women either a daily multivitamin/mineral (MVM) supplement or placebo for 12 months. Outcomes include change in MetaboAge and a range of metabolic, mental health, and musculoskeletal measures such as insulin sensitivity, mood scores, and muscle function. Participants are women aged 40–60 of Chinese, Malay, or Indian ethnicity with BMI 23–35 kg/m2, and those with major comorbidities or conflicting supplement use are excluded. The trial is conducted at the Institute for Human Development and Potential in Singapore and is designed to test whether improving micronutrient status can modify midlife health trajectories.

Who should consider this trial

Good fit: Asian (Chinese, Malay, or Indian) women aged 40–60 years with BMI 23.0–35.0 kg/m2, proficient in English and willing to follow the protocol, are the intended participants.

Not a fit: Women with diagnosed diabetes, recent cancer, autoimmune disease, those taking certain medications or overlapping supplements, or planning major diet or medical changes are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the supplement could lower biological metabolic age and improve metabolic markers, mood, and muscle function, potentially reducing longer-term chronic disease risk.

How similar studies have performed: Observational studies have linked higher B-vitamin and vitamin D levels with better metabolic and mental health, but randomized trials of broad MVM supplements in midlife Asian women are limited.
