Vitamin D is a crucial factor in the maintenance of health. Recognizing that many people fail to achieve optimum levels of this vitamin from sunshine and their daily diets, health experts are increasingly recommending supplementation. Research shows that for supplementation purposes, the D3 form of vitamin D is the superior form of this micronutrient.
A recent systematic review and meta-analysis compared the efficacy of vitamins D2 (ergocalciferol) and D3 (cholecalciferol) in improving vitamin D status. Published in the journal Nutrients by researchers from India, a total of 24 studies were examined in the review, 22 of which were subjected to meta-analysis. The researchers found that, compared to the D2 form, the D3 form was more efficacious in improving levels of vitamin D.
Moreover, the D3 form of vitamin D was also found to be more effective than the D2 form in reducing serum levels of parathyroid hormone. Produced by the parathyroid glands and playing a key role in regulating levels of calcium in the blood, parathyroid hormone is considered a biomarker of bone mineral metabolism.
