What dose?
Here’s a good little program for niacin.
Start with 500mg twice a day. It’s best after food, but not necessary. I ain’t gonna lie, that first flush is going to likely concern you. However, it’s totally safe albeit quite uncomfortable. The second dose that day will seem less intense. Do that for about a week, then bump that up to 2000mg a day. Spread that out how you want, but try to get that 2000mg a day into for a month. After two weeks you should really start to feel that you have a lot less inflammation. If you want to push it harder, and are liking it, go up to 3000 - 5000mg per day.
AZLiberty and I have both done 10g a day or more on occasion. All results were fantastic. After the high dosing, back it off to 1000 - 2000mg per day for a maintenance dose. Step down in the same increments are you stepped up. I STILL flush, but have grown to like it quite a lot - especially first thing in the morning.
Note: Upping the dosage does not mean the flush will get worse. In fact sometimes a lower dosage can cause a more severe flush in my experience. Do not fear the high doses. Further, the flush can be a little more intense, hit you within 3 minutes, but last a lot less longer if you dissolve the niacin powder (FLUSH NIACIN) in water and drink it down rather than taking a pill.
