Neurodegenerative disorders are progressive conditions that damage and destroy nerve cells in the brain and spinal cord, including Alzheimer's disease, Parkinson's disease, and Huntington's disease. These conditions are caused by the accumulation of abnormal proteins, mitochondrial dysfunction, oxidative stress, and nutritional deficiencies that accelerate nerve cell death. The Vitamin B3 test is the most important nutritional marker for supporting brain health in neurodegenerative disorders.

Neurodegenerative disorders are caused by the progressive breakdown and death of nerve cells in the brain and nervous system. The primary mechanisms include accumulation of abnormal proteins like amyloid-beta plaques and tau tangles in Alzheimer's disease, loss of dopamine-producing neurons in Parkinson's disease, and genetic mutations affecting the huntingtin protein in Huntington's disease. Additional contributing factors include oxidative stress, mitochondrial dysfunction, inflammation, and nutritional deficiencies that accelerate nerve cell damage over time.
The Vitamin B3 test is the most important blood test for supporting brain health in neurodegenerative disorders because it measures niacin and nicotinamide levels, which have demonstrated neuroprotective effects on brain cells. While neurodegenerative disorders are primarily diagnosed through clinical neurological examinations, brain imaging like MRI and PET scans, and sometimes genetic testing, the Vitamin B3 test helps identify nutritional deficiencies that may influence disease progression and overall neurological wellness. Maintaining optimal B3 levels supports cellular energy metabolism and may help protect nerve cells from oxidative damage.
You should get tested if you notice progressive memory loss, difficulty with familiar tasks, confusion about time or place, trouble with coordination or movement, tremors or muscle stiffness, changes in mood or personality, or difficulty speaking or finding words. Testing is especially important if you have a family history of Alzheimer's, Parkinson's, or Huntington's disease, or if cognitive and motor symptoms are interfering with daily activities. Early nutritional assessment through blood work can help identify deficiencies that may be addressed as part of comprehensive neurological care.

What this means
Your Nicotinamide level is slightly below the optimal range, which may contribute to fatigue, reduced energy production, and decreased cellular function. While not severely deficient, this lower level suggests your body may not be getting enough Vitamin B3 to support optimal metabolism and energy needs.
Recommended actions
Increase intake of B3-rich foods like chicken, turkey, tuna, salmon, and peanuts
Consider a quality B-complex supplement or standalone niacin supplement after consulting with your healthcare provider
Ensure adequate protein intake as your body can convert tryptophan to B3
Retest in 2-3 months after dietary changes or supplementation to track improvement
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
