B Vitamins

B vitamins are involved in numerous metabolic processes. Deficiencies can develop gradually and may go unnoticed until symptoms appear. Measuring B12, Folate, B1, and B6 together provides a broader view of B vitamin status than checking a single marker alone.

This test may be relevant for:

• Men who follow restrictive diets or have limited variety in their food intake
• Those experiencing persistent fatigue, concentration difficulties, or tingling sensations that could be related to nutritional factors
• Individuals who want a baseline measurement of their B vitamin levels

• Vitamin B12 (pmol/l, ref: 145-569): involved in nerve function and the production of red blood cells.
• Folate (Folic Acid) (nmol/l, ref: 10-42): plays a role in cell division and DNA synthesis.
• Vitamin B1 (Thiamine) (nmol/l, ref: 66.5-200): supports energy metabolism and nerve signal transmission.
• Vitamin B6 (nmol/l, ref: 20-125): involved in amino acid metabolism, neurotransmitter production, and immune function.

Low levels of one or more B vitamins may be associated with fatigue, cognitive changes, or neurological symptoms. Because B vitamins work together in metabolic pathways, a deficiency in one can sometimes affect the function of others. This panel may help identify whether B vitamin status could be a contributing factor to how you feel.

A blood sample is drawn at a certified sample point (afnamepunt). There are over 750 locations across the Netherlands. The procedure typically takes around 10 to 15 minutes. After placing your order, you can select a location and time that works for you.

This panel may be useful when experiencing ongoing fatigue, difficulty concentrating, mood changes, or numbness and tingling that could have a nutritional component. It can also be relevant for anyone who wants to check whether their dietary intake is reflected in their blood levels.

Results are presented with reference ranges for each vitamin. Values below the reference range may suggest insufficient intake or absorption, while values above the range could warrant further evaluation. A healthcare provider can help interpret the results in the context of your diet, symptoms, and overall health.

Your results are available in your personal dashboard, presented in a clear report with reference ranges for each marker. If any values fall outside the expected range, or if you have questions about what the results may mean for your situation, discussing them with a healthcare provider is recommended.
