Is Niacin a Missing Piece of the Puzzle?

Dr Mercola Is Niacin a Missing Piece of the COVID Puzzle? wrote:B vitamins may play an important role in COVID-19 prevention and treatment, according to two recent papers
Based on B vitamins’ effects on your immune system, immune-competence and red blood cells (which help fight infection), supplementation may be a useful adjunct to other prevention and treatment strategies
B vitamins can influence several COVID-19-specific disease processes, including viral replication and invasion, cytokine storm induction, adaptive immunity and hypercoagulability
Niacin appears particularly important. According to a recent paper, there appears to be a causative link between low niacin status and SARS-CoV-2 infection
SARS-CoV-2’s ability to invade your body is dependent on calcium signaling, which in turn is dependent on the presence of NAADP, which is formed from niacin. NAADP-dependent calcium signaling is responsible both for the inhibition of viral entry into cells and driving the virus out of already infected cells
