e-Pakiet niedobory witamin i minerałów — Vitamin & Mineral Deficiency Panel

Targeted nutritional assessment with 8 markers covering the most commonly deficient vitamins and minerals in Central European populations — vitamin D3, vitamin B12, folic acid, iron, ferritin, magnesium, zinc, and selenium. At 289 PLN (~67 EUR) with blood draw included. Essential screening for fatigue, hair loss, immune dysfunction, and suboptimal performance.

This panel targets the eight micronutrients most frequently deficient in Central European adults. The selection is evidence-based: each marker either has high population prevalence of deficiency, produces significant clinical symptoms when deficient, or both. Vitamin D3 (25-hydroxyvitamin D) deficiency affects 60-80% of Central European adults during winter months. At Wroclaw's latitude (51.1 degrees N), cutaneous synthesis is effectively absent from October through March. Deficiency impairs calcium absorption, weakens bones, suppresses immune function, and is associated with mood disorders. The Polish Endocrine Society recommends supplementation of 800-2000 IU daily for adults during autumn and winter. Vitamin B12 (cobalamin) deficiency is common in vegetarians and vegans (who lack dietary sources), older adults (reduced intrinsic factor and gastric acid), and patients on metformin or proton pump inhibitors. Deficiency causes macrocytic anaemia and progressive neurological damage (peripheral neuropathy, cognitive decline) that becomes irreversible if prolonged. Serum B12 below 200 pg/mL is definitively deficient. Folic acid (vitamin B9) works synergistically with B12 in one-carbon metabolism. Deficiency causes macrocytic anaemia identical to B12 deficiency and is a major risk factor for neural tube defects in pregnancy. Folate status is particularly important for women of reproductive age. Iron and ferritin together provide a complete iron status assessment. Serum iron reflects circulating available iron but varies significantly throughout the day. Ferritin is the gold-standard measure of iron stores — low ferritin (below 30 ng/mL) identifies depletion before anaemia develops. Iron deficiency is the world's most common nutritional deficiency, disproportionately affecting menstruating women, vegetarians, endurance athletes, and frequent blood donors. Magnesium deficiency is estimated to affect 10-30% of the general population. It causes muscle cramps, fatigue, insomnia, cardiac arrhythmias, and anxiety. Magnesium is depleted by stress, alcohol, caffeine, and common medications (PPIs, diuretics). Serum magnesium is an imperfect marker (only 1% of body magnesium is in serum), but low levels are clinically significant. Zinc is essential for immune function, wound healing, taste and smell, and testosterone synthesis. Deficiency is common in vegetarians, older adults, and patients with GI disorders. Selenium is critical for thyroid function, antioxidant defence, and immune regulation. Poland lies in a selenium-poor geological zone, making dietary deficiency endemic. At 289 PLN with blood draw included, this panel provides cost-effective nutritional screening. The equivalent at a German lab would cost 300-500 EUR.
