Supplements: A scorecard

The Harvard Health article "Supplements: A Scorecard" evaluates the efficacy and safety of various dietary supplements commonly used for health maintenance and disease prevention. It emphasizes that, unlike medications, dietary supplements are not strictly regulated by the FDA, allowing manufacturers to market products without providing evidence of purity, potency, safety, or efficacy. The article discusses the limited scientific support for many supplements, noting that while some, like vitamin D, have shown potential benefits, others lack substantial evidence or may pose health risks. It underscores the importance of obtaining nutrients primarily through a balanced diet and advises consulting healthcare professionals before initiating any supplement regimen.Regarding brain health and cognitive performance, the article suggests that the evidence supporting the use of supplements for cognitive enhancement is generally weak. Instead, it recommends lifestyle practices such as consuming a nutrient-rich diet, engaging in regular physical activity, ensuring adequate sleep, and managing stress to promote cognitive well-being. Given Harvard Health's reputable standing and the article's reliance on current scientific research, these recommendations are credible and practical for individuals seeking to improve brain health.
