Plants do not produce usable B12; what is advertised on algae or fermented foods are mostly analogs that the body cannot utilize. While the liver does store B12 for years, a depleted store only becomes noticeable late and then with serious consequences.<\/div>\n<p class=\"eh-archiv\"><a href=\"\/en\/wissen\/wie-der-koerper-funktioniert\/\">How your body absorbs nutrients \u2192<\/a><\/p>\n<p class=\"eh-archiv\"><a href=\"https:\/\/edenshealth.de\/en\/naehrstoffe\/#eisen\">Fact sheet on the nutrients page: Iron and B12, two that many people lack \u2192<\/a><\/p>\n<\/div>\n<h3>What&#039;s inside<\/h3>\n<p>Vitamin B12 in the declared form, usually as a tablet, lozenge, or drops.

Its contribution to normal energy metabolism is permitted, a distinction that advertising often blurs.<\/p>\n<h3>How it is taken<\/h3>\n<p>One serving per day is typical, regardless of meals. The intestines only passively absorb about one percent more from high doses, so high-dose products are neither a cause for concern nor a necessity. Excess B12 is excreted.<\/p>\n<div class=\"eh-portraet\" style=\"background:#eef5e6;border-left:4px solid #55883b;border-radius:10px;padding:20px 24px;margin:22px 0\">\n<p style=\"margin:0 0 6px;font-family:&#039;Instrument Serif&#039;,serif;font-size:22px;color:#22301f\">Knowledge, figures, research<\/p>\n<p style=\"margin:0 0 14px;line-height:1.6\">Why vitamin B12 is found almost exclusively in animal-based foods, who should pay particular attention to it, and what the figures say.<\/p>\n<p><a href=\"https:\/\/edenshealth.de\/en\/naehrstoffe\/#eisen\" style=\"display:inline-block;background:#55883b;color:#fff;font-weight:600;text-decoration:none;padding:10px 18px;border-radius:999px\">To the nutrient atlas \u2192<\/a><\/p>\n<\/div>\n<div class=\"eh-warn\">\n<h3>Good to know<\/h3>\n<ul>\n<li>Metformin (for diabetes) and proton pump inhibitors (PPIs) reduce B12 absorption when taken continuously, so monitoring blood levels is worthwhile.<\/li>\n<li>An abnormal B12 level should be checked by a doctor before taking high doses yourself, as it could indicate an absorption disorder.<\/li>\n<li>Vegans who are pregnant or breastfeeding should absolutely have their B12 intake monitored by a doctor.<\/li>\n<li>Not suitable for pets.
