Answer:
Dear
Sharon,
Autoimmune
thyroiditis or Hashimoto's thyroiditis is a condition caused by inflammation
of the thyroid gland.
It is
an autoimmune disease, which means that the body inappropriately attacks
the thyroid gland--as if it was foreign tissue.
Toxic
multinodular goitre (also known as toxic nodular goitre, toxic nodular
struma) is a form of hyperthyroidism - where there is excess production
of thyroid hormones.
It is the second most common cause of hyperthyroidism after Graves
disease.
L-Tyrosine
is required in order for the body to product thyroid hormone.
L-Tyrosine
is an amino acid which is a precursor of T4 (thyroxine) and T3 (Triiodothyronine).
L-tyrosine
is usually easily obtained from diet, there are no published studies
on the effects of supplementing in hypothyroidism .
L-Tyrosine
is a thyroid-hormone precursor, and supplementation may increase thyroid
hormone levels and boost your metabolism. Unfortunately, there's no
definitive evidence that this is so.
