ALCORA

ALCORA is a Germany-based health information platform that helps people in the DACH region compare dietary supplements using scientific evidence and transparent criteria. Its database covers 309 products and 21 active ingredients, including magnesium, vitamin D, omega-3, iron, vitamin B12, zinc, probiotics and curcumin. Rather than selling supplements, ALCORA provides product comparisons that assess bioavailability, purity and dosage, with a quality score from 0 to 100. Users can also compare total prices and the cost per effective dose.

The platform offers symptom checks, guides to supplement use, and calculators for dosage and nutrient needs. Users may enter blood test results and profile information for more personalised estimates; the site says these details remain in the browser and are not stored on its servers. Product prices and availability are checked daily, while product details are reviewed after reformulations or at least quarterly. ALCORA states that manufacturers cannot pay for higher rankings and discloses that it earns commissions through affiliate links.
