Do not take L-Tyrosine if you are already taking thyroid replacement pills or if you have high blood pressure.

Fatigue is a key symptom of an underactive thyroid, and while taking a B vitamin supplement is not a "cure" for hypothyroidism, it may treat the symptoms and help improve energy levels, according to TheNaturalHealthPlace.com.
