Fat oxidation, the process of breaking down fatty acids from both stored and dietary fat for energy, is critical for endurance during physical activity and weight control. However, not everyone's body uses fat efficiently during activity. In search of contributing factors, researchers investigated whether low vitamin C levels reduce fat burning. The study involved healthy young adults with either marginal or adequate vitamin C status. Participants completed a one-hour treadmill session at submaximal intensity while researchers measured fat oxidation. In a follow-up experiment, participants wi... exercise fat mitochondria vitamin c weight loss
Read morePoor strength and muscle mass are linked with many disease states, including obesity, diabetes, and chronic inflammation. A new study in mice shows that vitamin D is critical in building and maintaining muscle. Mice with higher vitamin D levels had greater strength and muscle mass and less fat mass than those with lower levels. Researchers fed mice three different diets over a period of 12 weeks to induce deficient, normal, and high blood concentrations of vitamin D. They measured the animals' strength and body composition before and after each dietary intervention. They also measured levels ... vitamin d obesity muscle
Read moreVitamin D is a fat-soluble vitamin that plays key roles in several physiological processes, including immune function. Research indicates that people who take supplemental vitamin D are less likely to have acute respiratory tract infections. Findings from a new study suggest that regular use of supplemental vitamin D reduces the risk of developing COVID-19. Vitamin D deficiency in the setting of COVID-19 can lead to over-expression of renin (an enzyme produced in the kidneys) and subsequent activation of the renin-angiotensin-system, a critical regulator of blood pressure, inflammation, and b... vitamin d covid-19
Read moreCOVID-19 is a respiratory illness caused by the SARS-CoV-2 virus. A growing number of studies have demonstrated the importance of vitamin D in regulating the immune system and controlling COVID-19 disease severity. Authors of a new study found that vitamin D supplementation shortened SARS-CoV-2 infection in vitamin D-deficient people. Vitamin D is a hormone that affects the expression of many genes important for immune function. Vitamin D deficiency is associated with greater risk of influenza and other respiratory infections. Unfortunately, one 2012 report (https://www.ncbi.nlm.nih.gov/pmc/a...
Read moreCurrently selected for this coming member's digest (/crowdsponsor) by team member Melisa B. SARS-CoV-2, the virus that causes COVID-19, stimulates the innate immune system, causing systemic inflammation that damages the lungs. Evidence suggests that those with the most severe cases of COVID are made sicker not by increased viral replication, but by unregulated inflammation. New evidence suggests that high dose intravenous vitamin C decreases inflammation, symptom severity, and death due to COVID-19. Vitamin C is essential for proper immune regulation. White blood cells produce harmful chemical... vitamin c covid-19
Read moreSeveral factors increase the risk of death due to COVID-19, including hypertension, obesity, male sex, advanced age, living at a northern latitude, and coagulopathy. Interestingly, poor vitamin D status is associated with all of these factors. Findings from a small, retrospective study revealed that vitamin D deficiency was a common feature among the majority of COVID-19 patients with severe outcomes. The study involved COVID-19 patients treated in the intensive care unit (ICU) at a tertiary care academic medical center in the United States. Of 20 COVID-19 patients for whom vitamin D levels w... vitamin d covid-19
Read moreVitamin C is essential for the synthesis of carnitine, a compound required for fatty acid oxidation – the utilization of fatty acids as energy – commonly referred to as "fat burning." Carnitine deficiency is associated with fatigue and poor exercise tolerance. Findings from a new study suggest that high dose vitamin C improves fatty acid oxidation. The two-part clinical study involved 22 men and women between the ages of 18 and 38 years. Fifteen of the participants had marginal vitamin C blood levels (less than 34 micromoles per liter) and seven had adequate vitamin C blood levels (greater th... exercise vitamin c weight loss
