Many years ago I tried a health supplement called Niacin (Vitamin B3) which used to give me a Niacin Flush/Rash. Then about 4 years ago I was diagnosed with Celiac Disease and started a strict Gluten Free diet.
Recently I tried taking Niacin again and was surprised to find that it didn't give me a rash, not even when taking 2 x 250mg/1500% RDA a day. I've read that Niacin Flush is caused when Niacin reacts with receptors in the body called PD1 receptors, so perhaps the Gluten Free diet is reducing the activity of these PD1 receptors.
Has anybody else tried taking Niacin either before or after starting a Gluten Free diet? It would be interesting to hear if anyone else has found that a Gluten Free diet prevents Niacin Flush.
