what’s 1 grain of NDT in Levo please?

[PixieElv]

hello lovely people

How much T4 and T3 are in 1 grain of NDT please?

Thank you

Suggest you look at the prescribing information for the product - for example, Armour:

But there is no clear and formal equivalence between desiccated thyroid and levothyroxine.

Thank you.

Do you know what happens to NDT if you store it at 5C? It says 15-30C but I’ve been keeping it in the fridge 🙄

1 grain NDT contains 38mcg T4 + 9mcg T3
