Vitamin D is essential for bone health, immune function, mood regulation, cardiovascular health, and disease prevention. Deficiency is extremely common, especially in Northern European climates like Germany. Results within 48 hours. Biomarker tested: Vitamin D3 (25-Hydroxyvitamin D) - storage form of vitamin D, most accurate indicator of vitamin D status. Optimal levels (>30 ng/mL or >75 nmol/L) support: bone density and calcium absorption preventing osteoporosis; immune system function and infection resistance; mood and mental health (low levels linked to depression, SAD); cardiovascular health; muscle strength and physical performance; reduced cancer risk.

A vitamin D test measures the level of 25-hydroxyvitamin D in your blood — the most accurate indicator of your body's vitamin D status. Vitamin D is essential for calcium absorption, bone health, immune function, and mood regulation. Despite its importance, vitamin D deficiency is one of the most common nutritional deficiencies worldwide, affecting an estimated 1 billion people. Low levels are linked to increased risk of osteoporosis, fractures, autoimmune diseases, depression, and certain cancers. People living at higher latitudes, those with darker skin, office workers with limited sun exposure, and the elderly are particularly at risk.
