Thanks for the link James, I've been looking this morning to see where the concern between Niacin and diabetes came from. There are two studies quoted below which state that in the dose usually prescribed for heart patients, 1,000 mg, Niacin does not result in increased insulin resistence. In fact, they say the study indicates IMPROVED control of BG.
In dose of 2,500 mg. in diabetics who have poor BG control already, it has shown some negative effects. This is good to know to avoid the higher doses, but let's not through the baby out with the bathwater on this since many of us have or will have heart related issues.
"Multiple studies were conducted to study effects of nicotinic acid on exacerbating insulin resistance. One retrospective study suggested that the use of moderate doses of extended release nicotinic acid (average, 1000 mg/d) in reasonably controlled diabetics was associated with improved glycemic control with HbA1c levels decreased by 0.5% ± 0.3% due to aggressive hypoglycemic therapy; as most of these patients had their insulin or oral diabetes regimen intensified . Another retrospective study using unmodified niacin concluded similar results ."
