Thyroid extracts are thyroid extracts derived from the thyroid glands of usually bovine (beef) sources.
Where are they found?
Thyroid extracts are available as nutritional supplements in capsules and tablets.
Thyroid extracts have been used in connection with the following conditions (refer to the individual health concern for complete information):
| Science Rating | Health Concerns |
|---|---|
 | Hypothyroidism |
 Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit. | |
Who is likely to be deficient?
As thyroid extract is not an essential nutrient, therefore, no deficiency state exists.
How much is usually taken?
The recommended intake depends on the concentration, method of preparation, and quality of the thyroid extract. Follow the manufacturer’s recommendation on the label.
Are there any side effects or interactions?
No side effects or adverse reactions have been reported. However, people taking prescription thyroid hormones should consult their doctor before using non-prescription thyroid extracts.
