Clinically Studied Benefits (with research)
Evidence drawn from NIH/NCBI (PubMed/PMC), NIH Office of Dietary Supplements (ODS), MedlinePlus, and Cochrane Reviews.*
Additional Potential Benefits*
- Mood & well-being (population-specific; evidence mixed) — Low vitamin-D status is linked with mood outcomes in reviews. (NLM/PMC — 2020 review)
- Glucose metabolism — Magnesium status associates with insulin/glucose homeostasis. (NIH ODS — Magnesium)
- Common cold (zinc lozenges) — Some analyses show reduced duration with lozenges; product form differs. (NIH/PubMed — Cochrane, 2011)
- Falls (older adults; context-dependent) — Ca+D associated with modest fall reduction in some analyses. (NLM/PMC — Zhao, 2018)
- Synergy of Ca + Mg + D₃ + Zn — Complementary roles in bone/mineral balance and immunity. (ODS — Calcium; ODS — Vitamin D; ODS — Magnesium; ODS — Zinc)
- Personalization — Benefit magnitude depends on baseline diet/status and age; stay within RDA/UL. (ODS — Calcium)
