It is advisable to take the tablet with food to reduce possible stomach discomfort. The recommended daily dose should not be exceeded without consulting a healthcare professional.\u003c\/p\u003e\u003cp\u003eThis pack includes two bottles of 250 tablets each, providing a total of 500 tablets, enough for a prolonged treatment.\u003c\/p\u003e\u003ch2\u003ePossible Side Effects\u003c\/h2\u003e\u003cp\u003eHigh doses of niacin can cause side effects, the most common being skin flushing.
