This is a general info tweet:
If you see or hear the phrase "boost your immunity" just run in the opposite direction.
Your immunity is not a battery that you can charge, or a dial that you turn up or down.. it's a multitude of complex interconnected systems with multiple levels..
Your body has an innate immunity, active immunity, passive immunity, first line defense (skin, membranes), local immunity (mucosal, IgA), humoral and cell mediated immunity. It's built up over time based on all the pathogens and organisms you've been exposed to your entire life!
Stress, illness and poor nutrition can affect your immunity short term, and your genes play a role too. Reliable immunity from covid needs a need a specific type of immunity that is best achieved with a vaccine. So don't fall for BS advertising magic 'boosts' 4 a complex system!
Great question! So most multivitamins aren't really going to help as long as you follow a balanced diet. Still, there is some data regarding Vitamin D, but not enough to make a strong recommendation either way. Read more here:
