Beyond its key role in calcium homeostasis, vitamin D has been found to significantly affect the cardiovascular (CV) system. In fact, low levels have associated with increased CV risk, as well morbidity and mortality. The majority of effects this molecule are related directly or indirectly antioxidative anti-inflammatory properties. Generally, insufficiency is considered for 25-hydroxyvitamin (25(OH)D) between 21–29 ng/mL (corresponding 52.5–72.5 nmol/L), deficiency 25(OH)D less than 20 (<50 extreme 10 (<25 nmol/L). However, definition an optimal status, defined by 25(OH)D, remains controversial many extra-bone conditions, including disease. review, confounding factors affecting measurement status will be discussed. particular, available evidence on mechanism relation risk disease through antioxidant effect reported, also facing aspect regarding debate minimum blood level required ensure health.

Perinatal Vitamin D Deficiency Enhances Brown Adipose Tissue Thermogenesis in Weanling Rats

International Journal of Molecular Sciences, Год журнала: 2025, Номер 26(10), С. 4534 - 4534

Опубликована: Май 9, 2025

Perinatal vitamin D (Vit. D) deficiency (VDD) disrupts the development of key tissues involved in metabolic regulation, including endocrine pancreas, white adipose tissue, and skeletal muscle. Brown tissue (BAT), essential for thermoregulation energy homeostasis, may also be affected, but impact perinatal VDD on BAT physiology remains unclear. In this study, forty female Wistar rats were fed either a standard AIN93G diet (1000 IU Vit. D3/kg; control group, CT) (n = 20) or modified lacking (VDD group) six weeks prior to conception throughout gestation lactation. Male offspring evaluated at weaning (PN21) adulthood (PN180) after status was normalized through diet. We found that reduced total lipid droplet area, increased oxygen consumption, upregulated thermogenic gene expression weaning. Correspondingly, exhibited greater cold tolerance enhanced recruitment upon exposure (4 °C). Notably, normalization by fully reversed these changes, indicating while transiently enhances activity during early life, it does not produce lasting effects into adulthood.
