Vitamin D (calciferol) insufficiency has been linked to the progress of renal disease. Some variables, such as dietary status and sunshine exposure, contribute to vitamin D deficiency. The target of the research was to set the nutritional and vitamin D status of chronic kidney disease CKD patients before and after three months of dietary awareness, sun exposure, and calciferol supplementation. From January 2019 to July 2020, 60 males (45-55 years old) were randomly recruited from the National Institute of Urology and Nephrology's outpatient clinic in Cairo, Egypt. Stages 3–5 of CKD are used to categorize patients. All of the participants were divided into two groups: control and CKD. For all individuals, the assessment covered nutritional consumption, including the 24-hours recall questionnaire, anthropometric measurements, and will specific biochemical assays. According to the findings, CKD patients consumed more calories and were obese, as measured by their body mass index (BMI). The average daily protein consumption was higher than the recommended daily intake (RDI). Except for sodium being the highest, the average mineral consumption was within RDI, whereas vitamin D intake was less than 10% of RDI. CKD group's energy levels dropped from 95.4 % to 82.8 % of RDI, protein vitamin C, and fiber intake increased after three months of treatments. While sodium levels remained within the RDI, biochemical examination revealed significant improvements in vitamin D, PTH, creatinine, and urea levels. Eventually, both nutritional intervention and vitamin D supplementation improved CKD stages from stage 3 or 5 to stage 2.
