Kidney Failure/Renal Insufficiency/Chronic Kidney Disease (CKD)
Published in Charles Theisler, Adjuvant Medical Care, 2023
Vitamin D: Patients with kidney disease typically have low levels of vitamin D. Vitamin D is essential for healthy bones. Treatment with vitamin D3 is highly effective in increasing calcium absorption, promoting positive calcium and phosphorous balances, increasing serum calcium, reducing serum alkaline phosphatase, and improving skeletal x-ray and bony architecture.5

In brief, vitamin D3 is made in the skin from 7-dehydrocholesterol, a derivative of cholesterol present in human body, under the action of UV sunlight. Vitamin D2 (ergocalciferol) is derived from the plant sterol named ergosterol, present mostly in mushrooms. Vitamin D is considered a semi-essential steroid hormone because it is made in the body when human biological condition is normal. Long-term intakes of high doses of vitamin D are dangerous for the health and must be managed by a healthcare professional.
Neurofeedback in an Integrative Medical Practice
Published in Hanno W. Kirk, Restoring the Brain, 2020
Vitamin D deficiency is estimated to be around 70% in white and 95% in African-American populations in the US.34 Manifestations of vitamin D deficiency can include chronic fatigue, fibromyalgia, weakness, and mood disorders;35 symptoms that are seen in many patients who present for neurofeedback. Vitamin D3 levels can be measured with blood work. Healthy serum concentrations are in the range of 50–125 nmol/L for almost all people.36 However, daily supplementation of vitamin D3 of 1000–2000 IU is felt to be safe in those without obvious risk factors for over-supplementation.

Vitamin D, also known as calciferol, is a secosteroid that is essential for bone health and plays a variety of biological roles such as AMP production and inflammation regulation via immunomodulation [8]. Optimal exposure to sun produces adequate vitamin D, which is stored in body fat and primarily released during winters. Many, including health professionals, choose oral vitamin D supplements on account of concerns of sunburn and skin cancer, in addition to indoor lifestyles, religious practices, extreme weather, etc. Oral vitamin D comes in two different forms, namely, vitamin D3 (cholecalciferol) and vitamin D2 (ergocalciferol). Vitamin D3 is maximally found in fatty fish, fish oils, egg yolks, liver, fortified foods, and diets. Vitamin D2 is maximally found in mushrooms grown in ultraviolet light [21,22].

Vitamin D deficiency may be another potential confounding factor. It was previously postulated that individuals who work at night and sleep during the day may be insufficiently exposed to sunlight, which may lead to vitamin D deficiency (Ward et al. 2011). This hypothesis was confirmed in several epidemiological studies, as summarized in a recent review (Coppeta et al. 2018). Vitamin D3 is an important factor for bone structure and metabolism. Thus, vitamin D3 deficiency might have indirectly led to decreased bone mineral density and the development of osteoporosis among night shifts workers in these studies. However, in our study, we did not perform vitamin D3 determination due to the small quantity of the blood collected, which is another limitation of the present research. Moreover, it was difficult to assess vitamin D supplementation by the study participants as this was based on the questionnaire responses. The women inquired were often not aware they might be eating products enriched with vitamin D. Moreover, the women reported irregular vitamin D supplementation, and that was still another problem that hindered the estimation. The season of the year may have also contributed to vitamin D deficiency, because the study procedures were carried out in autumn.
Serum Levels of Thyroid Hormone, Vitamin B12, Vitamin D3, Folic Acid, and Ferritin in Chalazion
Published in Ocular Immunology and Inflammation, 2022
The biologically active form of the vitamin D3 is produced in the skin upon exposure to ultraviolet-B light.23 Serum vitamin D3 level plays a significant role in pathogenesis of some inflammatory skin disorders and rosacea by regulating expression of antimicrobial peptides in human keratocytes.24,25 Increased serum vitamin D3 levels have been described in rosacea patients compared to controls and it is thought that alterations in levels may play a role in pathogenesis of chalazion because there are many common pathophysiological mechanisms responsible for these two diseases.26 According to the results of this study, there are no significant differences in the levels of vitamin D3 between chalazion patients and healthy control, and this result suggests that there is no relationship between serum vitamin D3 level and chalazion pathogenesis.
