The Great Vitamin D Debate 🤔: Is It Really Useless?

Vitamin D is the subject of a lot of controversy right now after the Endocrine Society made new recommendations in June 2024 suggesting that routine screening for vitamin D was not necessary, and routine supplementation was not beneficial for the average person. Today I'm looking into how they came up with this recommendation and what hundreds of studies have shown over the years, to put this recommendation in context. Everyone agrees that vitamin D is critical for life and no one is suggesting that we don't need it, but questions remain around whether we need to take a supplement or if we can find it naturally, and if so, whether we need to measure blood levels and what the optimal blood level should be.
