20 Vitamins and Supplements to Boost Immune Health for COVID-19

COVID-19 comes with cold and flu-like symptoms. Vitamins B, C, and D, as well as zinc, may help boost your immune system and fight the illness, similar to how they can help with a cold or flu.

Vitamin C

Vitamin C can help fight a cold faster or alleviate cold symptoms if taken before getting sick. It can reduce inflammation, including lung inflammation, which is a severe symptom of COVID-19. Starting vitamin C supplements when you’re healthy can be beneficial.

Vitamin D

Vitamin D helps maintain optimal blood levels of calcium and phosphorous. You can get vitamin D from sunlight, supplements, and food. Adequate vitamin D levels can also protect against respiratory infections.

According to studies published in the Journal of Pharmacology and Pharmacotherapeutics, vitamin D supplementation significantly reduces the chance of respiratory tract infections.

B Complex vitamins

Vitamin B6 is essential for a healthy immune system. Ensure you get enough vitamin B through supplements, diet, or a multivitamin.


Zinc lozenges or cold remedies can help reduce the duration of rhinovirus colds. Zinc also aids symptoms such as nasal congestion, drainage, sore throat, and cough. It stimulates the production and activation of T-cells, which respond to infections.
