I've been taking Probiotics since around 1999 and have never had the flu or have ever been to a Dr. Probiotics is not man made like the flu shot and antibiotics which both come from labs there is nothing man made that can kill any Virus on contact like Probiotics can. So when u go to the hospital with the C Virus and u are feeling bad and then the nurse gives that good ole antibiotic and says this will make u feel better but by an hour later u start to feel like you are on your death bed then that's why. I go around people all the time with the flu and have never caught it and another heath problem probiotics gets rid of is Asthma and most cancers which are considered a fungus but you have to stay on Probiotics your whole life so I guess that's why people don't use it and you can't just buy any Probiotics the higher the cultures the stronger it is we use 25 Billion CFU'S which is pretty strong. ANTIBIOTICS Should never be used on someone who is weak and dying. At times antibiotics are very necessary in order for us to fight an infection, they do unfortunately target and reduce the good, friendly bacteria as well as the harmful bacteria causing the actual infection.'In fact, research has shown that antibiotics decrease the diversity of gut bacteria in just three-four days, and depending on your diet, the effect of this can last for months to even years. Antibiotics also goes for Animals too Dr's are supposed to give Probiotics a hour after antibiotics but won't because Probiotics isn't regulated by the FDA so that's why so many people die because the antibiotics make their body so weak. So while everyone is stuck at home I am able to go out without having to wear mask like all the people waiting for a stupid vaccine that will most likely come with extra harmful additives like Mercury in the flu vaccine.
