If you’re looking for simple ways get the most from your immune-boosting jab, you’re in luck. Because research shows that taking an ordinary multivitamin enhances vaccine effectiveness.
Vaccines help your immune system to fight off infections by building protective antibodies, and a healthier immune system does a better job of producing those antibodies. To that end, research shows that a supplement such as a multivitamin can enhance the effectiveness of vaccination by improving natural immune function.
Studies of this connection have examined responses to flu vaccines in older people, whose immune systems are typically less responsive. Vaccines against Covid-19 are too new to be studied in a similar way.
Multivitamins enhance vaccines by providing key immune-boosting nutrients including vitamins A (including beta-carotene), B6, B12, folate, C, and D. Key minerals include zinc, selenium, iron, and copper.
