Thymus Extracts
Thymus extracts are extracts derived from the thymus glands usually of young calves (bovine). The thymus is one of our major immune system glands. It is composed of two soft pinkish-gray lobes lying in bib-like fashion just below the thyroid gland and above the heart. To a large extent, the health of the thymus determines the health of the immune system. The thymus is responsible for many immune system functions, including the production of T lymphocytes, a type of white blood cell responsible for "cell-mediated immunity." Cell-mediated immunity refers to immune mechanisms not controlled or mediated by antibodies. Cell-mediated immunity is extremely important in the resistance to infection by certain bacteria, yeast (including Candida albicans), fungi, parasites, and viruses (including herpes simplex, Epstein-Barr, and the viruses that cause hepatitis). Cell-mediated immunity is also critical in protecting against the development of cancer, allergies, and autoimmune disorders such as rheumatoid arthritis. The thymus gland also releases several hormones, such as thymosin, thymopoeitin, and serum thymic factor, that regulate many immune functions.
- 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.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
This supplement has been used in connection with the following health conditions:
| Used for | Amount | Why |
|---|---|---|
Bronchitis | 3 mg per 2.2 lbs (1 kg) body weight daily |  [3 stars] Thymus extract from calves, known as Thymomodulin, has been found to decrease the frequency of respiratory infections in children who were prone to such infections. |
Allergies and Sensitivities | 120 mg per day of thymomodulin |  [2 stars] Thymomodulin, a special preparation of the thymus gland of calves, has been shown to prevent allergic reactions to food in a double-blind study of allergic children. |
Hay Fever | 120 mg daily purified thymus polypeptides | [2 stars] A thymus extract known as Thymomodulin has been shown in studies to improve the symptoms of hay fever and allergic rhinitis. |
Hepatitis | 200 mg of crude extracts or 40 mg purified proteins three times per day | [2 stars] Proteins from the thymus gland, an important part of the immune system, may have a beneficial effect in people with chronic hepatitis B and C. |
Immune Function | 1 to 1.5 mg thymus polypeptides per 2.2 lbs body weight | [2 stars] The thymus gland is responsible for many immune system functions. A thymus extract known as Thymomodulin has been shown to improve immune function in some people. |
Asthma | Refer to label instructions |  [1 star] A thymus extract known as thymomodulin has been shown to improve the symptoms and course of asthma, presumably as the result of restoration of proper immune function control. |
HIV and AIDS Support | Refer to label instructions | [1 star] In one trial, a thymus extract known as Thymomodulin improved several immune parameters among people with early HIV infection, including an increase in T-helper cells. |
