I've had hay fever since I was a little kid, every year in late spring/early summer. Usually a month straight of sneezing. Ever since taking these I don't get hay fever anymore. Also, in Jan. 2017 I got acute Bronchitis which started out as the flu. I've had the flu before so I know what it feels like. It's awful, but you don't die from it. This was something else entirely. I was on the verge of it turning into pneuomonia and was near death. The NP prescribed me levaquin, said I was so sick if she gave me a regular antibiotic I would end up in the hospital. I got better, but knew I could never let that happen to me again. I started taking this stuff right after. I haven't been sick with either the cold or flu since and I never get a flu shot. At the time of writing it's July 2021. Just one thing, take MK7 K2 with it otherwise it'll calcify your arteries
