Thyroid hormones come in a variety of formulations and brand names.
Natural products made of dried thyroid glands from beef and pork are sold as Armour Thyroid, Thyroid Strong and Thyroid USP.
They are generally quite inexpensive, but dosage levels may vary. That is why endocrinologists usually prescribe synthetic products such as Synthroid or Levothroid.
When people develop a sluggish thyroid gland they often feel tired and weak. They may become constipated, sensitive to cold or anemic.
They may also suffer with dry skin and hair, thick brittle fingernails and have shortness of breath when they exercise.
Some people report clumsiness, weight gain, or puffy eyes.
Thyroid problems are diagnosed with blood tests. The best is one that measures thyroid stimulating hormone, or TSH.
This test also helps determine the proper dose of thyroid hormone for treatment.
