In this study, researchers assessed vitamin D3 levels in adolescents, finding a suboptimal average of 22.00 ng/ml, and demonstrated that supplementing with 1000 IU/day of vitamin D3 significantly raised levels and improved physical and mental potential over two months.

This paper reviews various vitamin deficiencies, including vitamin D, and highlights their potential health impacts. It does not report new research findings but discusses current recommendations and risks associated with these deficiencies.

This study reports that the epidermis is both a source and target for vitamin D3's active form, influencing skin and hair follicle differentiation through a calcium-mediated pathway.

This study found that human keratinocytes' sensitivity and response to vitamin D3 analogues vary based on cell density, serum availability, and calcium concentration.

This study demonstrated that VD3 significantly enhanced the proliferation and differentiation of epidermal stem cells in a murine skin defect model, leading to improved wound healing, potentially through activation of the PI3K signaling pathway.

Vitamin D is crucial for skin health and managing skin diseases.

This review explores how vitamin D3 analogs could target various skin processes and diseases, potentially offering selective and effective treatments beyond psoriasis, but reports no new clinical findings.

This study found that 1,25-dihydroxyvitamin D3 promotes hair growth and regeneration in mice by prolonging the anagen phase and counteracting DHT's inhibitory effects, suggesting its potential therapeutic role for androgenetic alopecia.

This review discusses the role of vitamin D and its receptor in maintaining skin and hair follicle health, but it reports no new clinical findings.

This chapter discusses the production, metabolism, and mechanism of action of Vitamin D, including its role in calcium and phosphate metabolism and its function in the epidermis and hair follicles, without presenting new research findings.

This article outlines the potential for upregulating the vitamin D receptor in treating hair disorders, emphasizing the need for further studies to evaluate vitamin D's role in the hair cycle.

Vitamin D3 affects cell differentiation in specific skin areas.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

In this study, synthetic vitamin D3 analogs stimulated hair growth and formation of normal hair follicles in nude mice, unlike the natural form 1,25 dihydroxyvitamin D3.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This study indicates that vitamin D3 administration may protect rat hair follicles from radiation-induced damage, as evidenced by maintained follicle numbers and increased Vitamin D receptor activity in treated skin.

This study demonstrated that a daily oral supplement of 1000 mg Kera-Diet® improved hair and nail conditions in women experiencing acute telogen effluvium and brittle nail syndrome over three months.

This review assesses the role of vitamins A, B, C, and D in treating dermatologic conditions and highlights promising applications, although further research is required to confirm their efficacy.

This review examines the role of vitamin D and its receptor in skin functions, exploring mechanisms regulating proliferation, differentiation, immunity, and tumor suppression, without reporting new research findings.

This case report details a severe instance of VDR-II where intravenous calcium infusions, administered nightly, successfully improved clinical, radiological, and biochemical signs of rickets without alopecia despite ineffective calcitriol therapy.

This article reviews the role of vitamin D and its metabolites in regulating calcium homeostasis and highlights their effects on the intestine, kidney, bone, and parathyroid gland, without reporting new clinical results.

In this case report, an ointment containing 1.24R-dihydroxyvitamin D3 was effective for treating follicular keratosis of the chin but did not provide lasting benefits after treatment ended.

In this study, VD(3) pretreatment increased hair follicle formation in a rat model by promoting dermal papilla cell differentiation, suggesting potential for hair regeneration therapy.

This review explores the biological functions of vitamin D, highlighting how deficiency may increase the risk of various diseases, but reports no new clinical results.

In this study, distinct clinical responses and long-term resistances were observed in two pediatric patients with vitamin D-dependency type II, associated with abnormalities in their skin fibroblast interactions with 1,25-(OH)2D3.

In this study, 1,25-dihydroxyvitamin D3 inhibited growth and promoted differentiation in normal hair follicle cells but did not affect cells from a patient with vitamin D-dependent rickets type II, assisting in potential rapid diagnosis of the condition.

This article reviews the multifaceted roles of vitamin D beyond bone health and notes its potential involvement in reducing risks of certain cancers and autoimmune diseases, but it presents no new clinical results.

This study found that vitamin D receptor activation in primary keratinocytes can occur independently of the 1,25-dihydroxyvitamin D₃ ligand, likely through interaction with retinoid X receptors.

This review examines the various functions of vitamin D and its receptor in regulating skin processes, highlighting their role in cell differentiation, immunity, and tumor suppression, but reports no new clinical results.

This review examines how vitamin D and its receptor regulate various skin functions, such as cell differentiation and immunity, and explores the mechanisms involved, without reporting new clinical results.
