B Vitamin Test for Fatigue and Low Energy
What this test measures
Nicotinamide
Nicotinamide has been shown to have neuroprotective effects. Low levels of this biomarker could potentially increase the risk of neurodegenerative disorders such as Alzheimer's and Parkinson's disease.
Nicotinic Acid
Low levels of nicotinic acid can increase the risk of heart disorders as niacin deficiency can lead to altered lipid profiles, including increased LDL cholesterol and decreased HDL cholesterol.
Vitamin B2 (Riboflavin)
Vitamin B2 is essential for the body to produce red blood cells and hemoglobin, which carries oxygen through your body. A deficiency can lead to a decrease in the number of these cells, causing anemia.
Vitamin B1 (Thiamine), Blood, LC/MS/Ms
Some studies suggest that people with high levels of homocysteine (a type of amino acid) have twice the usual risk of developing Alzheimer's disease. Taking vitamin B1 (Thiamine) could lower the body's levels of homocysteine, potentially reducing this risk.
Vitamin B5 (Pantothenic Acid)
A deficiency in Vitamin B5 can potentially impact the function of the adrenal glands, as this vitamin is critical for the production of adrenal hormones. This can lead to symptoms like fatigue, body aches, unexplained weight loss, low blood pressure, lightheadedness, and loss of body hair.
Vitamin B6
Vitamin B6 is important in the creation of hemoglobin in the blood, which is used to transport oxygen in red blood cells. A deficiency can lead to a specific type of anemia where the body has enough iron, but it can't use it properly to produce hemoglobin.
Vitamin B12
Atrophic gastritis is a condition that can cause vitamin B12 deficiency. This is because it damages the cells in the stomach that help absorb vitamin B12.
