Eating a variety of fruits and vegetables each day promotes healthy biological pathways
which helps protect us from disease.
4. Maintain a healthy gut: 70% of our immune system resides in our gut. Gut permeability
contributes to low level inflammation and supresses our immune system. Avoid foods that

inflammation. Chronic inflammation is associated with chronic disease which can put you at
risk for developing flu and serious flu related complications.

1. Vitamin C: Studies suggest that therapeutic doses of Vitamin C assists in alleviating and
reducing symptoms of colds and flu.
2. Echinacea root: This herb has immune enhancing and immune modulating activities which
can assist in the treatment of acute infections such as cold and flu. It also has anti-
inflammatory effects which can alleviate upper and lower respiratory symptoms associated
with bronchial inflammation.
3. Sambucus Nigra (Elder Berry): The key indications for this herb is in the treatment of
influenza, the common cold and other acute viral infections.
4. Vitamin ACE, Zinc and selenium: Vitamin A, C, E as well as Zinc and selenium plays an
important role in a healthy functioning immune system. Talk to your pharmacist or health
care provider about an immune boosting multi-vitamin to support your immune system
during flu season.
5. Garlic (Allium Sativum): Research studies conducted on aged garlic for the treatment of
acute colds and flu found that garlic had positive immune boosting effects and reduced the
severity of cold and flu symptoms.
