Community Discussion Forum What’s the Phe? Exchanges and Mg of PHE Reply To: Exchanges and Mg of PHE

Avatar of Breanna

Fifteen milligrams of phe is equal to one exchange. For example someone who is allowed 300 milligrams of phe could also say they are allowed 20 exchanges, because it means the same thing. Counting milligrams of phe is more exact, because exchanges are rounded off. For example something that says it has no exchanges might actually have around one to five milligrams of phe, which could make a huge difference for someone who has a very low phe tolerance.
