A new study has emerged as a significant ray of hope for millions living with heart disease, revealing that personalized supplementation of Vitamin D can markedly reduce the risk of heart attacks when doses are precisely tailored to meet a patient’s individual needs.
Presented at the American Heart Association conference, the research indicated that customized Vitamin D therapy reduced the chances of major cardiac events by an impressive 52%. The comprehensive study was conducted at the Intermountain Medical Center from April 2017 to May 2023, involving 630 adult patients who had pre-existing heart conditions.
Most participants in the study showed Vitamin D levels that were considered inadequate for optimal health (below 40 nanograms per milliliter). Researchers divided patients into two groups: one received individualized Vitamin D doses to maintain the required healthy levels, while the other received only standard medical care.
The results proved highly encouraging: out of 107 major cardiac events recorded during the study, heart issues affected 18% of the control group, compared to only 16% of the Vitamin D treatment group.
While the outcomes are considered highly promising by experts, they caution that the study is still in its preliminary phase. More extensive and comprehensive research is necessary before any definitive conclusions can be drawn or widely implemented in routine clinical practice.
