Most Supplements Are Useless and Potentially Harmful, Say Top Scientists
Professor Tim Spector and Dr. Sarah Berry explain why most supplements are ineffective and potentially harmful for healthy adults. Unlike the post-war era when vitamin deficiencies were common, today's problem is fiber deficiency and lack of plant diversity, not vitamin shortages. Traditional supplements often contain synthetic chemicals that bypass natural absorption mechanisms and can stress organs. The scientists discuss exceptions like folic acid for pregnant women and B12 for vegans, but emphasize that 95% of people get adequate vitamins from food. They introduce a new prebiotic supplement concept containing 32 whole plants that preserves food structure and delivers 54,000 beneficial compounds, contrasting with reductionist single-chemical approaches that ignore plants' complex nutritional matrices.
