Vitamin D, Epigallocatechin Gallate, D-chiro-inositol and Vitamin B6 in Uterine Fibroid
The study will evaluate the impact on uterine fibroids' volume of a combination of natural molecules including Epigallocatechin gallate, Vitamin D, D-chiro-inositol and Vitamin B6. The patients will be evaluated at baseline and after three months of treatment with placebo or product.
Effects Of Vitamin D On Bone, Muscle, And Adipose Tissue In Obese Subjects
Obesity has emerged as a risk factor in the onset of bone, muscle and adipose tissue impairments that are further aggravated by vitamin D deficiency. A link of an active bone-muscle-adipose axis is represented by Wnt pathway. This study will test the hypothesis that vitamin D improves bone, muscle, and …

Effects of Early Vitamin D3 Supplementation on Clinical Outcomes for Critically Ill Patients
There are no clear international guidelines for dosing vitamin D based on deficiency severity. Therefore, a new clinical trial is needed to evaluate the benefits of early vitamin D supplementation in maintaining sufficient levels for critically ill patients. The investigators conducted a multicenter clinical trial in Taiwan focusing on vitamin …
High Dose Interval Vitamin D Supplementation in Patients With Inflammatory Bowel Disease Receiving Biologic Therapy
The investigators will be administering oral high dose interval vitamin D, concurrently when participants are receiving biologic therapy for their inflammatory bowel disease. The investigators will be collecting some additional bloodwork and questionnaires at the time of participants infusions.
Vitamin D and Its Metabolites Quantification in Adipose Tissues of Obese and Non-obese Patients.
Vitamin D (VD) is a pleiotropic hormone, involved in many physiological processes including calcium and phosphorus absorption. The VD metabolism begin to be well-known and involves a hepatic hydroxylation (mediated by enzymes, which belong to the cytochrome P450 family) leading to the production of the 25(OH)D, which corresponds to the …
A Randomized Controlled Trial of Vitamin D Supplementation on Salivary Biomarkers and Cariogenic Oral Microbiome
The goal of this clinical trial is to compare the treatment effect of vitamin D supplementation and topical fluorides in the population having vitamin D deficiency and Initial Carious Lesions (ICL) on the progression of ICL in teeth. This study aims to observe the changes in the International Caries Detection …
High-Dose Vitamin D Supplementation for ADT-Induced Bone Loss in Older Prostate Cancer Patients
This phase III trial tests whether high-dose vitamin D works in treating androgen-deprivation therapy (ADT)-induced bone loss in patients with prostate cancer who are undergoing androgen-deprivation therapy. Vitamins are substances that the body needs to grow and develop normally. Vitamin D helps the body absorb calcium. Calcium is one of …
