Please note: The ‘DEFENCE’ Natural Herbal Boost is a formula to help you recover from viral infections as fast as possible. Use it only when you’ve already shown symptoms like fever, cough, sore throat, headache, runny nose, nausea, vomiting, diarrhea etc.

If you’re just looking for strengthening your immune system for prevention, you only need ‘IMMUNITY’. But we do recommend to have ‘DEFENCE’ in your counter too (at least 1-2 bottles) in case you or someone in your home shows symptoms. The sooner you take ‘DEFENCE’ after you showed symptoms, the faster you’ll recover.
