>>12011941 (pb) Look up niacin flush. B3/Niacin that gives you a FLUSH
IMPORTANT: You should NOT take a dose of 500 mg at first or you will be sorry. The flush will be seriously unbearable. Get some 100-mg pills and work your way up. Be aware that every time you increase the dose, you'll get a bad flush again, but your body will get accustomed to it.
WHAT HELPS: Drink a lot of water beforehand. Eat a full meal and take the niacin towards the end of the meal.
CAUTION: If you have high blood pressure, keep an eye on your blood pressure during the flush. It will spike a bit, just keep an eye on the numbers.
BONUS: If you have any cholesterol issues, this WILL HELP! If you find it helps you enough, ask your doctor about getting off of any statin drugs you're on.
