Vitamin D3 in fish oil extracted with limonene from anchovy leftovers
2020
Abstract Aiming to identify and assess the amount of fat-soluble vitamins in anchovy oil extracted with d-limonene from anchovy fillet leftovers via the UHPLC–HESI–MS advanced mass spectrometry analytical technique, this study shows that only vitamin D3 is present in anchovy by-product oil. The sum of the quantities of the three isomers of vitamin D3 amounts to 0.0815 μg vitamin D3 per g oil, namely a 81.5 μg/kg content, in good agreement with the typical amounts of vitamin D3 in fish oils (ranging from 18 to 350 μg/kg).
Density Functional Theory Calculated Raman Spectra of Ergocalciferol (Vitamin D2) and Cholecalciferol (D3)
2021
Density functional theory (DFT)-calculated Infrared and Raman spectra of Vitamin D2 and D3 are presented. The calculated results are compared with each other and with available experimental data. Applicability of Raman spectra for non-invasive optical Vitamin D sensors is discussed.
Use of nutritional supplement to improve performance in professional soccer players: A case report
2020
The aim of the study was to investigate the intake percentage and the satisfaction level of some nutritional supplements used by professional soccer players. Twenty-nine professional soccer players (age: 24.6 ± 5.2 years, body weight: 79.2 ± 4.9 kg, body height: 1.83 ± 0.05 m) belonging to a team of Serie A were interviewed on: frequency of use, tolerability, and acceptance of the supplements (creatine, β-alanine, whey protein, nitrates, vitamin D3, caffeine) proposed by the nutritionist team. This survey revealed a great inter-individual variability on the intake of the proposed supplements. All respondents (n = 29) said they take cholecalciferol (vitamin D3), 17 out of 29 creatine, 14 out…
Vitamin D Sources, Metabolism, and Deficiency: Available Compounds and Guidelines for Its Treatment
2021
Studies on vitamin/hormone D deficiency have received a vast amount of attention in recent years, particularly concerning recommendations, guidelines, and treatments. Moreover, vitamin D’s role as a hormone has been confirmed in various enzymatic, metabolic, physiological, and pathophysiological processes related to many organs and systems in the human body. This growing interest is mostly due to the evidence that modest-to-severe vitamin D deficiency is widely prevalent around the world. There is broad agreement that optimal vitamin D status is necessary for bones, muscles, and one’s general health, as well as for the efficacy of antiresorptive and anabolic bone-forming treatments. Food su…
Vitamin D Deficiency in Cushing’s Disease: Before and After Its Supplementation
2022
Background: The primary objective of the study was to assess serum 25-hydroxyvitamin D [25(OH)D] values in patients with Cushing’s disease (CD), compared to controls. The secondary objective was to assess the response to a load of 150,000 U of cholecalciferol. Methods: In 50 patients with active CD and 48 controls, we evaluated the anthropometric and biochemical parameters, including insulin sensitivity estimation by the homeostatic model of insulin resistance, Matsuda Index and oral disposition index at baseline and in patients with CD also after 6 weeks of cholecalciferol supplementation. Results: At baseline, patients with CD showed a higher frequency of hypovitaminosis deficiency (p = 0…
Effects of calcium, dairy product, and vitamin D supplementation on bone mass accrual and body composition in 10-12-y-old girls: a 2-y randomized tri…
2005
Little is known about the relative effectiveness of calcium supplementation from food or pills with or without vitamin D supplementation for bone mass accrual during the rapid growth period.The purpose was to examine the effects of both food-based and pill supplements of calcium and vitamin D on bone mass and body composition in girls aged 10-12 y.This placebo-controlled intervention trial randomly assigned 195 healthy girls at Tanner stage I-II, aged 10-12 y, with dietary calcium intakes900 mg/d to 1 of 4 groups: calcium (1000 mg) + vitamin D3 (200 IU), calcium (1000 mg), cheese (1000 mg calcium), and placebo. Primary outcomes were bone indexes of the hip, spine, and whole body by dual-ene…
Neridronate prevents bone loss in patients receiving androgen deprivation therapy for prostate cancer.
2004
Today, androgen deprivation therapy is a cornerstone of treatment for advanced prostate cancer, although it presents important complications such as osteoporosis. Neridronate, a relatively new bisphosphonate, is able to prevent bone loss in patients with prostate cancer during androgen ablation. Introduction: Androgen-deprivation therapy (ADT) is a cornerstone of treatment for advanced prostate cancer. This therapy has iatrogenic complications, such as osteoporosis. The aim of our study was to evaluate the efficacy of neridronate, a relatively new bisphosphonate, to prevent bone loss during androgen ablation. Materials and Methods: Forty-eight osteoporotic patients with prostate cancer, tre…
Znaczenie i rola witaminy D w praktyce farmaceutycznej
2022
Pierwsze doniesienia o witaminie D pojawiły się w pierwszej połowie XX w. Jej odkrycie wywarło istotny wpływ na prewencję i leczenie krzywicy, a także umożliwiło poznanie i udokumentowanie roli w regulacji równowagi gospodarki wapniowo-fosforanowej. Dalsze doniesienia sugerują również inne istotne dla zdrowia właściwości witaminy D, w tym wpływ na układ mięśniowy, nerwowy, immunologiczny, krążenia, gospodarkę węglowodanową, otyłość, ryzyko wystąpienia chorób nowotworowych, a także (istotne dziś) zagadnienie wpływu na przebieg i zapadalność na COVID-19. Wyróżniono sześć form witaminy D różniących się strukturą łańcuchów bocznych. Do grupy witaminy D zaliczamy: cholekalcyferol (witamina D3) p…
