Impact of Vitamin D status on age at menopause: A prospective cohort study

Calcium levels, closely tied to Vitamin D, significantly impact female health. However, the link between Vitamin D and menopause, its onset, and symptom severity remains unclear. This study aimed to examine the impact of Vitamin D supplementation on the age at menopause, menopausal symptoms, hormonal levels, and bone density in women. A 2-year prospective study of 100 menopausal women, grouped by Vitamin D levels (<20 ng/mL and >30 ng/mL), analyzed menopausal age, symptoms, hormone levels, and bone density. The results show that the women with vitamin D levels below 20 ng/mL had later menopause, more severe symptoms, lower estrogen, higher follicle-stimulating hormone, poorer bone density, and reduced quality of life than those with levels above 30 ng/mL, with all differences statistically significant (P < 0.05). Finally, I concluded that the vitamin D deficiency in menopausal women is linked to delayed menopause, severe symptoms, and poor hormonal and bone health. Adequate levels may support better menopausal health.
