Instead, it may have changed early protein handling, giving muscle tissue a stronger early supply of essential amino acids needed for new muscle-protein production.”

“Some evidence suggests that adding vitamin C to green tea might increase the bioavailability of the catechins present in green tea. Consumers of green tea commonly add milk, lemon, or other substances to their tea.”

“The Endocrine Society defines optimal blood levels of vitamin D as 40 to 60 nanograms per milliliter (ng/mL). Unfortunately, approximately 40 percent of people living in the United States are vitamin D deficient, based on Endocrine Society standards.”

The patients with low vitamin D levels spent an average of six days longer on mechanical ventilation compared to patients with higher levels.”

“Many medications accelerate vitamin D inactivation, including commonly prescribed blood pressure medications such as nifedipine and spironolactone. Learn more about vitamin D in our comprehensive overview article.”
