Adrenal Tissue Concentrate (bovine)
Also known as: Adrenal extract, adrenal glandular, adrenal support, bovine adrenal concentrate, Adrenal Tissue Concentrate (bovine)
Overview
Adrenal tissue concentrate is a supplement derived from the adrenal glands of cows (bovine), and sometimes pigs or sheep, typically sourced from slaughterhouses. It is marketed as a natural remedy for a variety of conditions, including stress, fatigue, adrenal insufficiency, Addison’s disease, asthma, eczema, and depression. The supplement contains a mixture of adrenal gland components, which may include trace amounts of hormones such as cortisol and adrenaline. However, the quality of available evidence supporting its use is very limited, consisting mostly of anecdotal reports and small, uncontrolled studies. There are no robust randomized controlled trials (RCTs) or systematic reviews specifically evaluating the efficacy of adrenal tissue concentrate for human health outcomes. Due to the lack of rigorous scientific evidence, its benefits and safety remain largely unconfirmed.
Benefits
Currently, there is no robust evidence from randomized controlled trials (RCTs) or systematic reviews to support the efficacy of adrenal tissue concentrate for any health condition. No secondary effects with supporting evidence have been identified in peer-reviewed literature, and no population-specific benefits have been established. Therefore, effect sizes and clinical significance are not applicable due to the lack of evidence. Claims of benefits related to stress reduction, fatigue alleviation, or support for adrenal function are not substantiated by scientific research. The use of this supplement should be approached with caution due to the absence of proven benefits.
How it works
The hypothesized mechanism of action for adrenal tissue concentrate involves providing adrenal hormones or their precursors to the body. However, it is unclear whether orally ingested adrenal tissue concentrate is effectively absorbed or biologically active in humans. Theoretically, it may interact with the hypothalamic-pituitary-adrenal (HPA) axis, a critical system for regulating stress response and hormone production. Despite these theories, there is no direct evidence in humans to confirm these interactions or identify specific molecular targets. The absorption and bioavailability of the supplement remain unknown, making it difficult to ascertain its true impact on the body.
Side effects
The overall safety assessment of adrenal tissue concentrate is generally considered low risk, but it is not well-studied. Common or uncommon side effects are not reported in the available literature. A rare, theoretical risk exists of disease transmission from animal tissues, although no documented cases have been reported. Drug interactions are possible if the supplements contain active hormones, such as cortisol or thyroid hormones, but this is not standardized or regulated. Caution is advised for individuals with hormone-sensitive conditions. Due to the lack of safety data, it is not recommended for pregnant or breastfeeding women, children, or individuals with autoimmune or endocrine disorders. Consumers should be aware of the potential risks associated with unregulated ingredients and the absence of comprehensive safety evaluations.
Dosage
There is currently no established minimum effective dose, optimal dosage range, or maximum safe dose for adrenal tissue concentrate. Timing considerations and form-specific recommendations are also not established. The supplement is typically available in capsule or tablet form, but absorption factors remain unknown. No required cofactors have been identified. Due to the lack of scientific evidence supporting its use, specific dosage guidelines cannot be provided. Consumers should be aware that there is no proven safe or effective dosage, and use should be approached with caution.
FAQs
Is there evidence to support the use of adrenal tissue concentrate?
No, there is no evidence to support the use of adrenal tissue concentrate for any health condition. Claims about 'adrenal fatigue' or 'adrenal support' are not scientifically validated.
Are there any safety concerns with adrenal tissue concentrate?
There is a theoretical risk of disease transmission from animal tissues, although no documented cases exist. The supplement may also contain unregulated ingredients, posing potential risks.
How should adrenal tissue concentrate be taken?
There are no specific recommendations for timing or administration, as no clinically significant effects are expected based on current evidence. Use should be approached with caution.
What results can I expect from taking adrenal tissue concentrate?
Based on current evidence, no clinically significant effects are expected. Misleading claims about 'adrenal fatigue' or 'adrenal support' are not supported by scientific evidence.
Research Sources
- https://www.webmd.com/vitamins/ai/ingredientmono-941/adrenal-extract – This WebMD article provides a narrative review of adrenal extract, concluding that there is no good scientific evidence to support its use for any condition. It also mentions a theoretical risk of disease transmission from animal tissues, although no documented cases have been reported. The review serves as a reliable summary of available evidence, highlighting the lack of primary research supporting its efficacy.
- https://pubmed.ncbi.nlm.nih.gov/29502560/ – This study involved a laboratory analysis of 12 over-the-counter adrenal support supplements in the US. The key finding was that all supplements contained small amounts of thyroid hormone, and most contained at least one steroid hormone. This highlights potential risks of hidden ingredients in unregulated supplements, though it does not assess clinical outcomes or safety in humans.
- https://www.va.gov/WHOLEHEALTHLIBRARY/tools/adrenals.asp – This resource from the Department of Veteran Affairs provides general information about adrenal glands and related conditions. It does not specifically address adrenal tissue concentrate as a supplement, but it offers context on adrenal health and the importance of evidence-based approaches to treatment.
- https://academic.oup.com/endo/article-abstract/63/4/431/2775243 – This older research article focuses on the effects of adrenalectomy on pituitary ACTH content and adrenal regeneration. While it provides insights into adrenal physiology, it does not directly relate to the use of adrenal tissue concentrate as a supplement or its potential benefits.
- https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2022.1001065/full – This research article explores the role of the adrenal gland in metabolic homeostasis and its response to stress. While it offers valuable information on adrenal function, it does not specifically address the use or efficacy of adrenal tissue concentrate as a dietary supplement.
