The Food and Drug Administration (FDA) has issued a warning to consumers, advising them to avoid two supplement brands sold primarily at gas stations due to potential serious health risks. The alert, released earlier this week, highlights concerns about undisclosed and potentially dangerous ingredients within these products.

While the FDA did not immediately specify the names of the brands in the public announcement, it stated that laboratory testing revealed the supplements contain substances not listed on their labels. These undisclosed ingredients could interact negatively with medications, exacerbate existing health conditions, or cause adverse reactions in consumers.

The FDA's warning underscores the importance of caution when purchasing dietary supplements, particularly those sold outside of traditional pharmacies or health food stores. Gas stations and convenience stores often carry supplements with less stringent quality control measures, increasing the risk of contamination or mislabeling.

The agency urges consumers who have purchased or used these supplements to discontinue use immediately and consult with a healthcare professional if they experience any adverse effects. The FDA continues to investigate these products and will provide further updates as more information becomes available. This action is part of the FDA's ongoing efforts to protect public health by identifying and addressing potentially harmful dietary supplements circulating in the marketplace.

Consumers are encouraged to report any adverse events related to dietary supplements to the FDA's MedWatch Adverse Event Reporting program. The FDA’s website provides detailed information on dietary supplements and consumer safety tips.
