Why Doctors Distrust Dietary Supplements Despite Their Popularity

Dietary supplements remain a divisive topic among medical professionals. While these products are widely used in Russia, doctors often hesitate to endorse them. The debate centres on safety, regulation, and scientific backing—key areas where supplements differ sharply from prescription drugs.

Unlike medications, dietary supplements face far looser controls. The World Health Organization (WHO) and other global health bodies do not directly oversee their production or sale. Instead, supplements are classified as food under minimal EU-wide rules, such as permitted vitamins and minerals. Stricter limits on nutrients like selenium and vitamin D will only take effect from 2026. Meanwhile, pharmaceuticals must comply with rigorous Good Manufacturing Practice (GMP) standards, ensuring consistency and safety.

The European Food Safety Authority (EFSA) offers scientific guidance on food safety, including supplements, but its advice is not legally binding. The WHO provides general nutritional recommendations, though these lack enforcement. As a result, the quality and contents of supplements can vary widely.

Many doctors remain sceptical because most supplements have not undergone the same clinical trials as drugs. Without robust evidence, physicians struggle to assess their true benefits or risks. This uncertainty clashes with their priority: treatments that deliver proven, predictable results for patients.

The gap between supplement popularity and medical approval persists. Doctors continue to favour therapies backed by solid research and strict regulation. Until supplements meet similar standards, their role in healthcare will likely remain contentious.
