The study of drugs involves testing a single compound to see what it does. Drugs act alone. A nutrient, on the other hand, closely interacts with other nutrients and is dependent on having adequate amounts of all of its supporting nutrients. Studying a single nutrient in isolation of all other nutrients is a failed concept that may be suitable to drugs, but is definitely not suitable for nutrients. Yet, this is exactly what is done in clinical studies, using the randomized, placebo-controlled, cross-over, large prospective studies that are called the “gold standard” of evidence-based medicine (EBM).
