The other day, someone at my gym approached me and lamented that he could spend nearly every waking hour of his life executing the countless viral health and longevity recommendations popularized by internet influencers and podcast hosts, and he’d still feel that he is falling behind. In 2016 the global supplement market amounted to $135 billion. That figure is projected to hit nearly $310 billion within the next four years. Some of these interventions have limited uses, while others range from the absurd to the truly harmful. It’s a shame that people are spending their money and energy on such things — even more so because the key to a longer, healthier life is no mystery.
