Unlike most animals, humans do not have the ability to manufacture vitamin C. We have to get adequate amounts in our diet because vitamin C is another nutrient that we can’t live without.

Unfortunately, most Americans do not get nearly enough.

What’s more, the U.S. government’s recommendation — 90 mg of vitamin C daily — is, quite frankly, silly. The only thing such a paltry intake can do is prevent scurvy.

A mere 90 mg of vitamin C daily simply isn’t enough to maintain normal body function. It falls far short of preventing many serious vitamin C deficiency diseases, such as heart disease.

Food sources for vitamin C include fruits and vegetables — but most Americans don’t eat enough of those.

In our toxic world, it is important to supplement with 3,000 to 5,000 mg of vitamin C daily, if your stomach can tolerate it. If you get diarrhea, lower the dose.
