Natural Thyroid Extracts
overall review score: 3.5
⭐⭐⭐⭐
score is between 0 and 5
Natural thyroid extracts are supplements derived from the thyroid glands of animals, typically pigs or cows. They contain a combination of hormones including thyroxine (T4), triiodothyronine (T3), and other thyroid proteins, and are used to support thyroid function in individuals with hypothyroidism or thyroid hormone deficiencies. These extracts are considered a more 'natural' alternative to synthetic thyroid medications, although they require careful dosing and medical oversight.
