Elevated Blood Sugar

Niacin can increase blood sugar levels by affecting insulin resistance and glucose metabolism. This is particularly concerning for individuals with diabetes or glucose intolerance.

Niacin, also known as vitamin B3, can lead to elevated blood glucose levels, a condition known as hyperglycemia. This occurs because niacin can increase insulin resistance and affect glucose metabolism. Symptoms may include increased thirst, frequent urination, blurred vision, fatigue, and slow-healing sores. In individuals with pre-existing diabetes or glucose intolerance, niacin supplementation may exacerbate these conditions, potentially leading to significant metabolic imbalances and requiring adjustments to diabetes management strategies. Regular monitoring of blood glucose levels is crucial for individuals taking niacin, especially those with diabetes.
