Why it is done this way
We test before we infuse, and we say when a tablet would do
Not everyone who asks for an infusion needs one, and we will tell you when you do not.
Intravenous delivery earns its place when absorption is the problem — after gut surgery, with inflammatory bowel disease, in severe deficiency, or when the oral dose required cannot be tolerated.
Chelation is for a documented heavy-metal burden, established by testing and confirmed by re-testing afterwards. It is not offered speculatively.
