Dietary Nitrate and Nitrite Concentrations in Food Patterns... : Nutrition Today. Dietary nitrate and nitrite are found primarily in green leafy vegetables and root vegetables, such as spinach and beets, and have become popular because of potential cardiovascular health benefits.1 Dietary nitrate is reduced to nitrite in saliva by bacteria on the tongue and further metabolized to nitric oxide (NO) and various nitrogen oxide metabolites in the stomach before being circulated through the blood after absorption.2 In conditions of low oxygen availability such as living at high altitudes and exercise-induced hypoxia in muscle, nitrite can be converted into NO, a free radical gas that serves as a signaling molecule essential for endothelial function and metabolic regulation.

Through these mechanisms, dietary nitrate consumption increases plasma nitrite concentration, reduces resting blood pressure, and improves vascular function.3 A conundrum exists concerning the potential health benefits and risks associated with consumption of dietary nitrate and nitrite. 1. 2. 3. 4.

Magnesium and Pain

Mechanism of Antinociceptive Action of Magnesium Although magnesium has no direct antinociceptive effects, it inhibits calcium ions from entering cells by blocking NMDA receptors, resulting in an analgesic effect. This analgesic effect is related to the prevention of central sensitization caused by peripheral tissue injury [3]. Central sensitization occurs due to the enhancement of neuronal properties in the nociceptive pathways of the central nervous system. It is triggered by repetitive nociceptive afferent inputs and eventually manifests as a prolonged reduction in the pain threshold.

UPDATE: The FDA Warns that Biotin May Interfere with Lab Tests: FDA Safety Communication

Food and Drug Administration (FDA) is updating our 2017 safety communication to remind the public, health care providers, lab personnel, and lab test developers that biotin, often found in dietary supplements, can significantly interfere with certain lab tests and cause incorrect results that may go undetected. The FDA wants to make the public and health care providers aware about biotin interference with lab tests so that patients, physicians, and laboratories can work together to help prevent adverse events.

The Paradox of Coenzyme Q10 in Aging

CoQ10 Supplementation in Aging: Effects on Life span and Longevity The possibility of increasing CoQ10 levels in different organs or tissues through dietary supplementation has been widely explored in recent decades. Studies in rodents [153,154,155,156,157] suggest that CoQ10 administration is able to increase the amounts of CoQ10 in plasma and liver significantly, and in heart, kidney and skeletal muscle moderately. Similarly, different authors have reported increased systemic levels of CoQ10 in humans after supplementing with CoQ10 at different daily doses (100 to 2400 mg) and duration (20 days, 3 or even 16 months) in multiple trials [158,159,160,161,162]. Regarding the safety of CoQ10 supplements, different assessments in human and animals (reviewed by Hidaka et al. [163]) concluded that the endogenous biosynthesis of CoQ10 is not influenced by exogenous inputs.

Product indiscriminate use of vitamin risks: A review: Critical Reviews in Food Science and Nutrition: Vol 0, No 0

This study aims to demonstrate, through bibliographic survey, the risks of indiscriminate use of vitamin products related to hypervitaminosis and major drug interactions which the multivitamins are involved. A bibliographic survey was conducted in the databases LILACS, SciELO, PubMed, Medline, Micromedex, Drugs.com and textbooks on the subject. Vitamins are commonly described as harmless products by the majority of the population, but these trace elements can interact with other substances, causing mild disconforts or treatment failure for the patient, severe consequences to the body and can lead to death.
