Tried and tested Protego and I recommend taking the herbal support especially at the start of sore throat, running nose ,feeling of fatigued and other indicators of flu.I am usually wary in trying new products however lately I noticed that my immune system needs support to fight off being sick as well as it should. I took the suggestion of a friend who has been taking Ninma products and is happy with it. It has only been a day since I started drinking Protego with hot water and a slice of lemon and I can feel the difference in my body. I feel less sick than I was before I took it.I can say that I am in my road to recovery .I am happy with how my body positively reacted to Protego.
