Abstract:
Vitamin D receptor (VDR) expression in the female reproductive tract explains the regulatory role of vitamin D on inflammatory cytokine and prostaglandin (PGD) synthesis. This study aimed to evaluate the effect of vitamin D on adolescents' primary dysmenorrhea and the relationship between Vit. D and adolescents' primary dysmenorrhea. Eighty-five adolescents were included in the current study. After a detailed evaluation, pelvic sonography was performed for all participants to rule out any pelvic pathology. Blood samples were collected to measure thyroid stimulating hormone (TSH), prolactin, glycosylated hemoglobin (HbA1C), and 25-hydroxyvitamin D (25[OH]D). Participants were administered vitamin D (50,000 IU weekly for five months), and their dysmenorrhea symptoms were evaluated before and after this period using the Visual Analog Scale (VAS) and the Verbal Multidimensional Scoring (VMS). The mean VAS and VMS scores of dysmenorrhea statistically decreased from 8.7±0.91 and 2.65±0.93 to 4.8±0.75 and 0.80±0.75, respectively, after vitamin D intake (p=0.03 and 0.025, respectively). Significant negative associations between 25(OH)D and VAS (R = -0.886; p<0.00001) and VMS of dysmenorrhea (R = -0.885; p<0.00001) were detected in this study. Vit. D could be a useful therapeutic option to reduce the severity of primary dysmenorrhea and could limit the use of non-steroidal anti-inflammatory drugs.

01:25Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
01:23Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...
01:17Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:22Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
