If you click on the link and scroll to the symptoms of high intake the text there is a bit worrisome. Is this accurate?

So don't take high doses.

As long as you don't have PKU, you should be fine. Don't take ridiculous amounts of it.

all of that said, if you are a healthy adult your liver has the neccessary enzymes present to either utilize the Phe, convert it to tyrosine, or breakdown the surplus into a harmless metabolite and excrete.

I can only imagine how hard that can be. Can't even eat anything with aspartame since it is dangerous and has Phe, like Equal or Nutra-sweet.
