Caught by LOOKING at the live page on 2026-07-30, right after\n   the template was switched to canvas.\n\n   Everything is scoped to `.bp-adv`, so nothing here can reach the rest of\n   bioprofile.com, and core blocks are styled BY ELEMENT so a heading, a\n   paragraph, a quote, a list, an image or a button inserted by hand inside the\n   advertorial comes out on-design with no class to remember.\n\n   Jesse's design feedback, 2026-07-29 23:38, point by point:\n   1. the light green and the dark green are the preferred colours; grey may be\n      used but the page must NOT open grey;\n   2. more colour and variation across sections, e.g. a colour block on the left\n      or the right side of a section, without overdesign;\n   3. ONE H1, plain text on white; everything else H2 or H3; an H2 may carry its\n      own background colour so the page can be read from the headings alone; an\n      H3 keeps its section background and gets a bigger font size;\n   4. reuse the results page design feel;\n   5. Written by \/ Verified by, the placeholder blocks and noindex stay.\n\n   COLOUR PROVENANCE. Not one hex is invented.\n   - #b7cb32  LIGHT GREEN, brand manual \"colours rejuvenation protocol\"\n              (R183 G203 B51). Same value as --bp-lime in\n              brands\/bioprofile\/brand\/tokens.md.\n   - #006b62  DARK GREEN, brand manual, nourish the cells (R0 G107 B98).\n   - #005859  brand manual primary teal, the value the brand is built on.\n   - #228a62  brand manual, challenge the body (R34 G138 B98).\n   - #7ca64c  brand manual, calm the mind (R124 G166 B76).\n   - #dbd4cd  brand manual \"additional color\", the warm neutral.\n   - #B7CB3329 is the brand token --bp-lime-soft (light green at 16 percent).\n   - the gradients are the brand token layer's own, copied verbatim.\n\n   SPECIFICITY NOTE. Elementor's global kit emits `.elementor-kit-6 h2` style\n   rules at (0,1,1). Element rules below are written `.bp-adv h2`, also (0,1,1),\n   and win on source order because this sheet is inline in the body while the\n   kit is a <link> in the head. Component rules that MUST NOT lose carry two\n   classes, e.g. `.bp-adv .wp-block-button__link`.\n\n   LAYOUT NOTE. Vertical rhythm uses `margin-block` and never the `margin`\n   shorthand, so the measure rule `.bp-adv-sec > * { margin-inline: auto }` can\n   centre a block without being outranked by its own element rule.\n   =========================================================================== *\/\n\n.bp-adv {\n  --bp-ink: #212527;\n  --bp-teal: #005859;\n  --bp-forest: #006B62;\n  --bp-emerald: #228A62;\n  --bp-olive: #7CA64C;\n  --bp-lime: #B7CB33;\n  --bp-lime-soft: #B7CB3329;\n  --bp-sand: #DBD4CB;\n  --bp-white: #FFFFFF;\n  --bp-foot: #6b6b6b;\n  --bp-grad-dark: linear-gradient(237deg, rgba(0,88,89,0.00) 62.94%, #005859 100%), linear-gradient(90deg, rgba(34,138,98,0.00) 40%, #228A62 100%), #006B62;\n  --bp-grad-lime: linear-gradient(110deg, rgba(183,203,51,0.00) 36.06%, rgba(183,203,51,0.25) 97.65%), #FFFFFF;\n  --bp-font: 'Poppins','Segoe UI',Arial,sans-serif;\n  --bp-fs-h1: 44px; --bp-fs-h2: 31px; --bp-fs-h3: 24px; --bp-fs-pre: 15px;\n  --bp-fs-body: 17px; --bp-fs-small: 14px; --bp-fs-foot: 13px; --bp-fs-btn: 17px;\n  --bp-lh-body: 1.75;\n  --bp-s-1: 4px; --bp-s-2: 8px; --bp-s-3: 12px; --bp-s-4: 16px;\n  --bp-s-5: 24px; --bp-s-6: 32px; --bp-s-7: 44px; --bp-s-8: 72px;\n  --bp-measure: 760px; --bp-side: 40px;\n  --bp-radius-photo: 16px; --bp-radius-btn: 10px; --bp-radius-card: 20px;\n  --bp-shadow: 0 10px 30px rgba(0,88,89,0.10);\n  font-family: var(--bp-font);\n  font-size: var(--bp-fs-body);\n  line-height: var(--bp-lh-body);\n  color: var(--bp-ink);\n  background: var(--bp-white);\n  -webkit-font-smoothing: antialiased;\n}\n.bp-adv, .bp-adv * { box-sizing: border-box; }\n.bp-adv p, .bp-adv li, .bp-adv h1, .bp-adv h2, .bp-adv h3, .bp-adv blockquote,\n.bp-adv a, .bp-adv cite, .bp-adv span { overflow-wrap: break-word; min-width: 0; }\n\n\/* THE TOGGLE.

Der Transferrintest misst dieses Eiwei\u00df in Ihrem Blut.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Eisen ist ein Mineralstoff, den Ihr K\u00f6rper f\u00fcr Wachstum und Entwicklung braucht. Ihr K\u00f6rper nutzt Eisen, um H\u00e4moglobin zu bilden. Das ist ein Eiwei\u00df in Ihren roten Blutk\u00f6rperchen, das Sauerstoff von der Lunge in den Rest Ihres K\u00f6rpers bringt.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Eisen ist auch wichtig f\u00fcr gesunde Muskeln, Ihr Knochenmark und die Funktion Ihrer Organe. Ihr K\u00f6rper braucht Eisen au\u00dferdem, um einige Hormone zu bilden.<sup>[1]<\/sup><\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-adv-sec is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\" id=\"bp-waarom-het-ertoe-doet\">Warum Eisen wichtig ist<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Manchen Menschen f\u00e4llt es schwerer, genug Eisen aufzunehmen. Zum Beispiel wenn Sie starke Monatsblutungen haben, schwanger sind oder Ihr Baby stillen, h\u00e4ufig Blut spenden oder eine b\u00f6sartige Erkrankung, bestimmte Erkrankungen der Verdauung oder eine Erkrankung des Herzens haben. Auch Babys f\u00e4llt es schwerer, vor allem wenn sie zu fr\u00fch oder mit niedrigem Geburtsgewicht geboren wurden. Die meisten Menschen in den Vereinigten Staaten nehmen jedoch genug Eisen auf.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Zu wenig Eisen im K\u00f6rper ist die h\u00e4ufigste Ursache einer Blutarmut. Bei einer Blutarmut hat Ihr Blut weniger rote Blutk\u00f6rperchen als normal.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bei zu wenig Eisen k\u00f6nnen Sie sich schwach oder m\u00fcde f\u00fchlen, Ihnen kann schwindlig sein, Sie k\u00f6nnen kurzatmig sein oder einen Herzschlag mit abweichendem Tempo oder Rhythmus haben. Ein niedriger Eisenwert verursacht manchmal erst Beschwerden, wenn er sehr niedrig ist. Deshalb kann Ihre medizinische Fachperson auch ohne Beschwerden einen Eisentest veranlassen.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bei zu viel Eisen k\u00f6nnen Sie sich schwach oder m\u00fcde f\u00fchlen, Schmerzen in den Gelenken haben, vor allem in den Knien oder H\u00e4nden, Bauchschmerzen haben, weniger Lust auf Sex haben oder Schwierigkeiten mit einer Erektion haben. Ihre Haut kann sich auch grau, metallisch oder bronzefarben verf\u00e4rben.<sup>[1]<\/sup><\/p>\n\n<\/div>\n\n\n\n<div class=\"wp-block-group bp-adv-sec bp-adv-sec--wash is-layout-flow wp-block-group-is-layout-flow\">\n\n<h2 class=\"wp-block-heading\" id=\"bp-wat-je-waarde-zegt\">Was Ihr Transferrinwert aussagt<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Die Richtlinie des Labors<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Labplusarts, das Labor, mit dem BioProfile zusammenarbeitet, verwendet f\u00fcr Transferrin einen Referenzwert von 2,2 bis 3,6 g\/l.

Die Quelle \u00e4u\u00dfert sich zu den Eisentests insgesamt. Zeigen ein oder mehrere Ergebnisse, dass Ihr Eisen zu niedrig ist, kann das auf eine Blutarmut durch Eisenmangel, eine andere Form der Blutarmut oder eine erbliche Erkrankung des Blutes hinweisen. Nicht jeder Mensch mit niedrigem Eisen hat eine Blutarmut.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Transferrin zu hoch<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Auch hier spricht die Quelle \u00fcber die Eisentests insgesamt. Zeigen ein oder mehrere Ergebnisse, dass Ihr Eisen zu hoch ist, kann das auf zu viel Eisen hinweisen, das sich in Ihrem K\u00f6rper ansammelt, erblich oder durch eine andere Erkrankung, oder auf eine Erkrankung der Leber. Ein auff\u00e4lliges Ergebnis bedeutet nicht immer, dass etwas vorliegt, wof\u00fcr Sie medizinische Versorgung brauchen.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BioProfile arbeitet an eigenen Zonen pro Wert, von Risiko bis optimal.
