Summary
Your orange juice habit isn't protecting you from getting sick. But before you toss that bottle, here's what vitamin C is actually doing that's way more important. Turns out the whole "vitamin C prevents colds" thing is basically a marketing myth. The research shows it only cuts your cold by about 8% - that's maybe half a day shorter. Not exactly the immune shield we've been promised. But here's what gets me: we're completely missing what vitamin C actually does. This stuff is literally holding your body together. Without it, your blood vessels start falling apart. Your gums bleed. Your old wounds can reopen. That's scurvy, and yeah, it still happens today. What we cover: • Why that 1000mg vitamin C pill is mostly expensive pee • The collagen connection nobody talks about • How sailors figured out the scurvy solution 300 years ago • What actually happens when your body runs out of vitamin C Who this is for: Anyone taking vitamin C "for immunity" and wondering why they're still getting sick. The crazy part? Your body can only absorb about 200-400mg at once. So those mega-dose supplements are basically just making your kidneys work overtime. Sarah breaks down exactly how much you actually need and where to get it without wasting money on pills.
