A common, yet usually harmless side effect of niacin supplementation includes a temporary “flushing” sensation in the skin. This includes itching under the skin, warmth, redness, or tingly skin. Avoid alcohol as it can make the flushing sensation worse. Other side effects include mild dizziness, sweating or chills, nausea, burping, diarrhea, leg cramps, muscle pain, pain of the mouth, intestinal gas and insomnia. Large doses of Niacin can cause more serious side effects such as liver problems, gout, ulcers to the digestive tract, loss of vision, high blood sugar, irregular heartbeat and other serious problems. Consult with a healthcare professional before use if you are using antibiotics, cholesterol-lowering drugs, blood pressure medications, alpha-inhibitors or other medications. If you believe that you are experiencing any adverse reactions, please see your healthcare professional immediately. Each individual may react differently to any product or supplement. We always recommend that you consult with your healthcare professional prior to considering the use of this product or any supplement.*
