“Fatty acid utilization in the supplemented group was approximately four times greater than the vitamin C depleted group. Poor fatty acid oxidation during exercise was related to higher levels of fatigue.”

“Findings from a meta-analysis suggest that vitamin C might reduce the incidence of exercise-induced bronchoconstriction. Previous research demonstrated that vitamin C can triple respiratory tissue levels within an hour or two of a single oral dose of 1 or 2 grams.”

“Vitamin C does not act the same way. This is why it is VERY important to understand mechanisms and not make generalizations. Vitamin C is in constant homeostasis between oxidized and reduced forms and this depends on many factors including dose.”

“Vitamin C's immune-boosting and antioxidant properties can mediate the body's inflammatory response, reducing the symptoms or risk of various diseases. Evidence suggests that vitamin C can lower C-reactive protein, a marker of inflammation.”

“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.”

“Researchers gave people with long COVID either a combination of liposomal vitamin C and arginine or a placebo for four weeks. They measured their walking speed, strength, and endothelial function before and after the intervention.”

“I've talked previously about what I've referred to as the sweet spot: 40-60 ng/ml. Some studies have shown that the lowest all-cause mortality happens in that range. The upper range may be important because vitamin D can be toxic at very ranges.”

“From the article: > Patients administered vitamin C had a rapid and statistically and clinically significant improvement in mood state, but no significant change in mood occurred with vitamin D, the researchers discovered. [...] About one in five acute-care patients in our hospital have vitamin C levels so low as to be compatible with scurvy," added Hoffer.”

“Among deficient participants, vitamin C supplementation increased fat-derived energy expenditure during exercise four-fold compared to placebo. Plasma carnitine differed by vitamin C status and was related to fat oxidation during exercise.”

“Kale supplies folate, magnesium, vitamin K, fiber, lutein, and zeaxanthin; blueberries supply anthocyanins. Avocado adds fat, and a small feeding study found that avocado increased absorption of lutein and other carotenoids from salad.”
