Vitamin C can be useful in fighting off common cold and flu. We all know that, but did you know that Linus Pauling, the gentleman that found out that Vitamin C is used in the treatment of scurvy, said, multivitamins don’t work. Those who need them can’t afford them and those who can afford them don’t need them. We at Dr. Kats know, that not only do you need to take the right supplements, but you need to take the right amount of the right supplement. That is why every single one of our supplements has the right amount of the right thing.
