Capsule thyroid extract supplements are a natural way to support thyroid health. They contain desiccated thyroid gland from bovine or porcine sources, which provides a rich source of thyroid hormones. These supplements are often used by individuals with an underactive thyroid, or hypothyroidism, as they may help to improve energy levels, mood, and metabolism. Capsule thyroid extract supplements are available in various strengths and formulations, and should only be taken under the guidance of a healthcare professional. It is important to note that these supplements are not a substitute for prescription medication and should not be used to self-diagnose or treat thyroid conditions.
