Use this calculator to convert between different forms and units of thyroid hormone. Common
|
||||
synthetic, pure and natural dessicated forms are listed. The last section of the table provides
|
||||
input fields for a specified ratio of T3 to T4, and will give the dosages required for both the
|
||||
synthetic and pure forms. All dosages given are based on the "Grains" field at the beginning of the
|
||||
table, but editing any field will automatically update the rest to keep them in sync.

<strong>Changelog:</strong>
|

<p>
|

<ul>
|

<li>
|
||||
November 2024: Migrated to new web framework and fixed some buggy input.
|
||||
</li>
|
||||
<li>
|
||||
13th March 2024: Removed the synthetic/pure distinction as it was confusing and unnecessary
|
||||
bloat.
