B Vitamins Test
B vitamins are a class of water-soluble vitamins which play important roles in cell metabolism, converting food into fuel and metabolising fats and proteins. They are important for the nervous system and brain function as well as a healthy liver, hair, skin and eyes, and they also strengthens the immune system.
Understanding your B vitamin levels are especially important if you have elevated homocysteine levels. Elevated homocysteine is a risk factor for cardiovascular disease. It is a multifactorial condition with genetic and environmental factors involved, and can often be managed providing there are sufficient B vitamins.
