"Alternative" voices have been saying this about Vitamin D3 since the start of this whole mess. Is it really a surprise that most people living outside of our biological niche (warm, near-equator climates) lack this fundamental micro-nutrient and have so many health problems as a result? No, but what's surprising is how we still lack understanding of basic factors to good health - sunshine, nutrient-rich foods, regular exercise and adequate sleep. Now imagine if our healthcare resources were focused on that and other preventative lifestyle interventions. We might not even have a so-called pandemic on our hands.
