Raise RDA of vitamin C, D: Study urges health authorities to adjust guidance in light of COVID-19
Health authorities should reassess the Recommended Daily Allowance (RDA) of key micronutrients such as vitamin C and D to support the immune system, said a group of researchers.
A group of researchers from the New Zealand, US, UK, and Netherlands, said that the RDA of vitamin C should be increased to 200mg and vitamin D to 2000 IU in their review published in Nutrients.
“The immune system is more important than before to reduce the risk of infection. A low RDA is a risk factor for an impaired immune system,” one of the researchers, Dr Manfred Eggersdorfer told NutraIngredients-Asia.
“The industries and the authorities now have the opportunity and responsibility to adjust the RDA,” the professor for Healthy Ageing at the University Medical Center Groningen stressed.
