About BHT
Butylated hydroxytoluene (BHT) is a synthetic antioxidant primarily used as a preservative in foods, supplements, and cosmetics. Its main function is to prevent oxidation and extend shelf life. While BHT exhibits antioxidant properties and some in vitro antiviral activity, its primary use is not as an active ingredient for health benefits. The safety profile of BHT is complex, with concerns surrounding potential allergic reactions, endocrine disruption, liver effects, and conflicting evidence related to carcinogenicity. Regulatory bodies monitor and control BHT usage to ensure exposure remains within acceptable limits. Research continues to explore the potential long-term health effects of BHT exposure.

Scientific Evidence
Several studies available on PubMed and other scientific databases detail the effects of BHT. Key areas of research include: antioxidant properties and food preservation, in vitro antiviral activity against specific viruses (e.g., herpes simplex virus), endocrine disruption potential, liver enzyme activity, and carcinogenicity studies in animal models. Refer to EFSA (European Food Safety Authority) and FDA (Food and Drug Administration) reports for regulatory assessments.
