Great advice, Andrea.
Some people might be sensitive to even the smallest dosages, especially if not taken with food.
I have found that the benefits of niacin, when taken with avocados, seem to be many times greater than taken alone.
Niacin Contraindications

Hi Niacinamide has been found to cause Liver problems in some people and Nicotinic Acid ( Flush Niacin B3) should never be taken by people who are 'undermethylator.'
This has many symptoms and can be quite drastic if used by the wrong people. I suggest if you are, or thinking of using Niacin for any reason read up on being an 'undermethylator. ' before or if your having problems and already using it.
