Thank you for visiting LowBH4.org!

You likely landed here because you spotted something on a genetic report that you suspect might be causing reduced levels of BH4 (Tetrahydrobiopterin).

The LowBH4.org web site will only be able to scratch the surface, as an introduction to some of the BH4-related concepts, science & terminology; yet at the same time offers lots of links to other helpful and more detailed resources & references on the internet.

This is a complex subject. There has been so very much research published over the years, and more research is being conducted all the time. There is simply too much for one person to sift through and to know.

And yet, now there is consumer access to home genetic kits, and they have put the curiosity into many people, who obviously don't all have a degree in genetics & biochemistry.

Our mission here at LowBH4.org is to understand the subject well enough to try our best to explain it simply -- because for so many people now, low BH4 is a subject worth learning about.

“If you can‘t explain it simply, you don‘t understand it well enough.”
-Albert Einstein

We hope you enjoy your visit, and you too increase your understanding of low BH4.
