Research Design

Dr. Rhonda Patrick discusses the importance of well-designed research, particularly when evaluating the effects of vitamin D during COVID-19. She points out that for nutritional studies, unlike pharmaceutical drugs, it's crucial to have baseline measurements as people aren't starting from zero exposure. Randomized control trials should incorporate these factors to be effective and provide meaningful results. Surprisingly, some studies have been conducted without measuring vitamin D levels before supplementing, which she finds concerning for scientific rigor. Proper design is vital to ensure unbiased and accurate outcomes 1 .
