Vitamin B6, Plasma

Vitamin B6, in the form of Pyridoxal 5'-Phosphate (PLP), is critical for over 100 essential enzyme functions, particularly those governing amino acid and energy metabolism. The Vitamin B6, Plasma test measures your PLP levels, offering a clear assessment of your nutritional status. Low levels, sometimes recognized below 30 nmol/L, are associated with serious health concerns, including an increased risk for cardiovascular disease and chronic inflammatory conditions. This test is highly valuable for anyone concerned about optimal nutrient absorption or who is managing chronic health issues, ensuring this vital cofactor is sufficient for supporting your body's energy and metabolic pathways.
