Pandemic or not, it’s always a good idea to be proactive and keep your immune system strong. Taking care of yourself and staying healthy may help you avoid falling victim to any nasty bugs. As they say, prevention is the best medicine.

While the best defense is to get vitamins and minerals through a balanced diet, it’s not always convenient or even possible to get all of the essential nutrients your body needs through food. That’s why many people turn to supplements like vitamins, minerals and herbs to rev up their immune system.

From gut-loving probiotics to whole-body-boosting botanical blends, here are 12 affordable supplements for less than $25 — which is a small price to pay for good health.
