Prevention and Treatment of Viral Infections

(Including Covid, Flu, RSV and the common cold)

The providers at Carolina Total Wellness recommend the following lifestyle and supplement supports to optimize immune function, decrease viral transmission, reduce viral activity and support the body’s immune response to common viral infections.


Focus on eating foods that are organic and rich in antioxidants.  Try to eat 5 to 7 servings of vegetables and 2 to 3 servings of fruit every day.  Limit intake of sugar and processed foods.

Drink filtered water, avoiding plastics as much as possible. 

Limit intake of alcohol to no more than 2 drinks per week for women and 4 drinks per week for men.

Ensure adequate, quality sleep.  Aim for 7 to 9 hours a night, focusing on good sleep hygiene.

Integrate mindfulness and stress lowering practices every day.

Improve ventilation and air flow and utilize high quality air filters indoors, including home and work.
