The neuropsychiatric symptoms consist of, photophobia, headaches, insomnia, irritability, anxiety, limb pains, muscular weakness, asthenia, fatigue, lethargy, depression, memory loss, personality deterioration, confusion, disorientation, delirium, hallucinations and psychosis. The dermatological manifestations may include a sore or inflamed mouth and tongue, dermatitis, skin eruptions, skin inflammation.

About Vitamin B3

Chronic niacin deficiency causes the fatal condition called pellagra. For most individuals conditions never become this serious but illness can nevertheless occur often becoming evident in the early stages by personality deterioration such as mental and emotional illness. These psychiatric symptoms often get misdiagnosed as illnesses in their own right by doctors and psychiatrists unfamiliar with this simple biochemical imbalance, and they may resort to prescribing pharmaceutical drugs to manage symptoms without addressing the underlying cause. Once a blood measurement has confirmed the deficiency, the condition responds well to supplementation.

  • I started taking Nutrivitality every day to help prevent colds and found it to be very effective. I am eighty-seven years of age and so I need some help during the long winter months. I now have less colds and those I've had have been less severe and have cleared up quickly. Also, my general health has been much better.
