Vitamin Package

A comprehensive vitamin panel measuring vitamin D, B1 (thiamine), B2 (riboflavin), B6 (pyridoxine), B11 (folate), B12 (cobalamin), and methylmalonic acid (MMA) from a venous blood draw. MMA is included as a functional marker of B12 status, which can detect deficiency earlier than B12 levels alone.

Vitamin deficiencies are surprisingly common even among individuals who believe they eat well. This panel measures seven key markers spanning the fat-soluble vitamin D and the water-soluble B-vitamin complex, providing a thorough assessment of the vitamins most frequently implicated in fatigue, neurological symptoms, mood changes, and immune dysfunction in the northern European population. Vitamin D insufficiency affects a large proportion of the Dutch population, particularly between October and April when ultraviolet light exposure is too low for meaningful cutaneous synthesis. The B-vitamin complex supports energy metabolism, red blood cell production, and neurological function. B12 deficiency is particularly common among vegetarians, vegans, and older adults, and can cause irreversible neurological damage if left undetected. The inclusion of methylmalonic acid (MMA) — a functional biomarker that rises when B12 is insufficient at the cellular level — adds a layer of sensitivity that serum B12 alone cannot provide. Folate (B11) is essential for DNA synthesis and is of particular importance for women of childbearing age. Thiamine (B1) and riboflavin (B2) are less commonly measured but play important roles in carbohydrate metabolism and energy production. Pyridoxine (B6) supports neurotransmitter synthesis and immune function. Together, this panel provides actionable data for targeted supplementation rather than guesswork.
