Some customers have found that they have a bit of excess energy or feel very relaxed after taking Restore. This can be resolved by taking 1/2 scoop instead of a full scoop. It can also be resolved by taking it at a time of day in which a bit of energy or relaxation is not inconvenient for you.
In a minority of cases, customers who have taken Restore on an empty stomach have reported feelings of nausea. This problem can be resolved by taking it with food.
Some people report mild flushing/warmth of the face or chest. This is called "niacin flush" and it's a totally harmless result of taking large doses of vitamin B3 (niacin), and it’s a sign that the supplement is working. This symptom goes away within minutes and disappears completely with consistent usage.
