Many of you have seen excellent results in maintaining normal cholesterol levels with time-release niacin. Controlled Release Technology (CRT) is the latest technology for delivering niacin in a continuous, controlled rate over a 12-14 hour period. Flushing sometimes happens with time-release niacin as there can be fairly large surges of niacin released intermittently over a 6-8 hour period. However, flushing is far less likely with controlled release niacin.
