Regular exercises 30 minutes a day 3-5 times a week. Choose the right vitamin for the best results. The experts found that the more C the patients were given, the faster they recovered. In other words, the higher the dose, the more effective it was. But high doses of oral vitamin C can upset your tummy. And let’s face it, gas and diarrhea are the last things you want to be battling in the ICU. That’s why Drs “in the know” deliver C intravenously (IVC). And since you already have more lines running into you than the back of a cable box, sneaking in one more certainly won’t hurt. IVC has the added advantage of bypassing the stomach. It’s fed directly into your bloodstream, where it can go to work immediately. So if you or a loved one find yourself stuck in the ICU, ask your Dr about IVC. If he refuses to play along, then get permission to try oral vitamin C instead. It will cost you just pennies a day and could help get you home a bit sooner.
