You're aware that heavy water, in sufficient doses, is fatal right? It subtly shifts the equilibrium points of various life-critical chemical reactions and when the % of D2O in the body reaches roughly 50% then you start to die.

That's the point. If it didn't, it couldn't slow aging.

I'm not sure what kind of point you're trying to make here. Acetaminophen will kill you long before it reaches 1% of your body mass, as will most drugs. 50% represents an astoundingly wide theraputic window.
