Key Takeaways
- The FDA’s oversight of dietary supplements is largely post-market, leaving consumers to navigate a rapidly growing $60 billion industry with minimal pre-market regulation.
- Identical twins share a unique bond often stronger than other relationships, with profound grief felt when a twin is lost.
- Advances in research and proposed regulations aim to improve supplement safety and deepen our understanding of twin connections.
The Evolving Oversight of Dietary Supplements: A Balancing Act Between Safety and Accessibility
The Rise of the Supplement Industry and FDA Challenges
The dietary supplement industry has grown rapidly over the last three decades, evolving into a $60 billion market with over 100,000 products available worldwide. This growth has introduced significant challenges for regulatory oversight. The U.S. Food and Drug Administration (FDA), tasked with ensuring public safety, operates under the framework established by the Dietary Supplement Health and Education Act of 1994 (DSHEA). Unlike pharmaceutical drugs, dietary supplements are regulated as foods, requiring minimal pre-market oversight.
According to Dr. Kara Welch, director of the FDA’s Office of Dietary Supplement Programs, “The majority of products can likely and legally go to market without ever telling FDA.” This reliance on post-market regulation has raised concerns about consumer safety and product quality. While companies must register their manufacturing facilities and adhere to good manufacturing practices, pre-market safety reviews are not required.
The Structure-Function Claim Loophole
One key area of regulatory complexity lies in the structure-function claims that supplement companies are allowed to make. Statements such as “calcium builds strong bones” or “fiber promotes regular bowel movements” are common, yet these claims do not require FDA approval. Welch emphasizes the fine line between acceptable claims and those crossing into illegal territory, stating, “We have to review that in-house to determine whether the claim is again intended to be for the treatment, prevention, or cure of a disease.”
In some instances, companies exploit these ambiguities, leading to misleading marketing. For example, in 2022, the FDA reprimanded seven companies for falsely claiming their products could prevent or treat heart disease. Such cases illustrate the importance of stricter regulatory mechanisms.
Modernizing Supplement Oversight
The FDA has recognized the need to adapt its approach to match the complexities of the modern supplement industry. Dr. Welch highlights a legislative proposal that would require manufacturers to list their products with the FDA. This listing would include details about ingredients and the responsible brand owner. While this would not involve pre-market approval, it would give the FDA better visibility into the marketplace.
“We are looking to strengthen and modernize the dietary supplement oversight authorities,” Welch explains. The goal is to strike a balance between consumer access to supplements and enhanced safety measures. However, some critics argue that more robust pre-market scrutiny is necessary to protect consumers before potentially unsafe products reach store shelves.
The Role of Consumers in Ensuring Safety
Despite the regulatory gaps, consumers can take proactive steps to safeguard their health. The FDA and National Institutes of Health (NIH) provide resources to help individuals evaluate supplement quality and safety. Welch underscores the importance of collaboration between regulatory bodies, the industry, healthcare professionals, and consumers. “Most of the changes being discussed would be legislative changes, and all parties play a role in ensuring a safe, high-quality dietary supplement marketplace,” she adds.
Conclusion: Navigating a Complex Marketplace
The rapid growth of the dietary supplement industry has outpaced the FDA’s ability to regulate it effectively. While recent proposals aim to modernize oversight, the agency continues to rely heavily on post-market surveillance. Consumers, armed with credible information and resources, play a crucial role in navigating this complex landscape.

Understanding the Unique Bond and Challenges of Twins
The Mystery of Twins and Their Deep Connections
Twins have long fascinated scientists, psychologists, and society at large. The twin birth rate has increased by 70% since 1980, driven in part by advances in fertility treatments like in vitro fertilization. Despite the surge, much remains unknown about twins, particularly identical ones. Dr. Nancy Segal, a professor of psychology and director of the Twin Studies Center at California State University, Fullerton, has dedicated her career to unraveling these mysteries.
“Identical twins result when the fertilized egg splits sometime in the first two weeks after conception,” says Segal. “But why that happens is absolutely mind-boggling.” While fraternal twins are influenced by genetics and factors like maternal age and body composition, identical twin formation appears to be a spontaneous event, unlinked to any known hereditary or environmental triggers.
The unique relationship between twins, particularly identical ones, is often described as the strongest human bond. Segal notes that “the identical twin bond is reputed to be the closest of all human social ties,” even among twins who were separated at birth. These individuals often report feeling closer to their newfound twin than to siblings they were raised with.
How Twins Handle Loss
While twins often celebrate their bond, they also experience profound grief when that connection is severed. Segal has conducted ongoing research into how the loss of a twin impacts surviving siblings and their families. With over 800 survey participants, she has found that identical twins often feel the loss more deeply than fraternal twins.
“Even twins raised apart who’ve met for a short time feel the loss,” says Segal. “It’s different in a way, but you always have this sense of promise unfulfilled.” This deep grief may stem from the shared genetics and a mutual understanding of the world that identical twins often experience.
Interestingly, some of Segal’s work points to evolutionary psychology as a factor in the intensity of the grief. For identical twins, the loss represents not only a close familial bond but also shared reproductive potential. This unconscious biological drive may amplify the feeling of loss.
The Cultural and Genetic Influence
While cultural narratives often highlight twin bonds, Segal argues that genetics plays a larger role in their closeness. She explains that even twins raised in vastly different environments tend to seek out their similarities upon meeting.
“Identical twins raised together look for their differences, while those raised apart look for their similarities,” Segal observes. This instinct to connect is reinforced by the human tendency to gravitate toward others who resemble us, both physically and emotionally.
The perceived psychic connection between twins is also a topic of interest. Segal clarifies that this phenomenon is not rooted in supernatural abilities but in shared genetic influences. “Identical twins respond to the world the same way because they process information in very similar ways,” she explains.
Conclusion: Exploring the Twin Connection
The study of twins offers unique insights into human relationships, genetics, and psychology. From their extraordinary bonds to the profound grief they experience when separated, twins continue to captivate researchers and the public alike. Dr. Nancy Segal’s work emphasizes the importance of understanding these connections, not only for the twins themselves but also for broader insights into human behavior and development.
