For patients who don't want to ingest animal products, Thyrolar is an excellent synthetic alternative to Armour. Armour and Thyrolar have the same ratio of T4 to T3. They are equally reliable and effective when patients use high enough doses.

Armour and Thyrolar both contain 38 mcg of T4 and 9 mcg of T3. This is 4 parts T4 to 1 part T3 (the exact ratio is 4.22 to 1).

Men det er vel ingen T2, T1 eller T0 i dette produktet, er det det da? Likevel, særdeles interessant: "They are equally reliable and effective when patients use high enough doses." Da må man jo egentlig kunne skape dette forholdet med Levaxin og Liothyronin da, eller....?
