Viracid, when taken at the first signs of cold or influenza, can be an amazing anti-viral supplement.
Sinatrol is amazing at getting your sinuses to drain.
(Both of these supplements cannot be taken while pregnant or nursing) If you are pregnant or nursing I would recommend OrthoMune!
ViraKid is the anti-viral supplement that is chewable for kids! It has a fun grape flavor. It should be taken at the first signs of illness. It is one of the supplements to keep on hand now that school has started.
