The researchers point out that in the European Union, the average vitamin C requirement is 90 mg/day for men and 80 mg/day for women, while the Swiss Society of Nutrition recommends that, “everyone supplement with 200 mg to fill the gap for the general population, and especially, for adults age 65 and older.”
The Linus Pauling Institute, here in the US, recommends 400 mg of vitamin C per day for adults 50 years and older.
“Pharmacokinetic studies in healthy volunteers,” comment the researchers, “support a 200 mg daily dose to produce a plasma level of circa 70 to 90 μmol/L. Complete plasma saturation occurs between 1 g daily and 3 g every four hours, being the highest tolerated oral dose, giving a predicted peak plasma concentration of circa 220 μmol/L.”

NEW ORLEANS Medscape.com reported in March 2020 that researchers from the Department of Epidemiology, School of Public Health, Southern Medical University in China, determined that, “habitual fish oil supplementation was associated with a 13% lower risk for all-cause mortality, a 16% lower risk for CVD (cardiovascular disease) mortality, and a 7% lower risk for CVD events in the general population.
The study, Associations of Habitual Fish Oil Supplementation Population-based Cohort Study, which appeared in the British Medical Journal, used a total of 427,678 men and women aged between 40 and 69, who had no CVD or cancer at baseline were enrolled between 2006 and 2010 and followed up to the end of 2018.
