Supplements: What You Actually Need vs. What They're Selling You

The supplement industry made $69 billion last year. But how much of what's on that shelf do you actually need? In this episode Aurora breaks down the difference between what the science supports and what's just really good marketing. You'll learn why the FDA doesn't approve supplements before they hit shelves, which nutrients are genuinely hard to get from food alone, and which popular products are mostly expensive hype. Food-first, always — but with the nuance you actually need to make informed decisions. This episode is for educational purposes only and does not constitute medical or nutritional advice.
