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.

La prueba de transferrina mide esta prote\u00edna en tu sangre.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El hierro es un mineral que tu cuerpo necesita para crecer y desarrollarse. Tu cuerpo usa el hierro para fabricar hemoglobina, una prote\u00edna de tus gl\u00f3bulos rojos que lleva el ox\u00edgeno desde los pulmones al resto del cuerpo.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El hierro tambi\u00e9n es importante para tener m\u00fasculos sanos, para la m\u00e9dula \u00f3sea y para el funcionamiento de tus \u00f3rganos. Tu cuerpo tambi\u00e9n necesita hierro para fabricar algunas hormonas.<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\">Por qu\u00e9 importa el hierro<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A algunas personas les cuesta m\u00e1s obtener suficiente hierro. Por ejemplo, si tienes reglas abundantes, est\u00e1s embarazada o alimentas a tu beb\u00e9 con tu propia leche, donas sangre a menudo, o tienes una enfermedad maligna, ciertos problemas digestivos o una enfermedad del coraz\u00f3n. A los beb\u00e9s tambi\u00e9n les cuesta m\u00e1s, sobre todo si nacieron antes de tiempo o con bajo peso. La mayor\u00eda de las personas en Estados Unidos s\u00ed obtiene suficiente hierro.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tener poco hierro en el cuerpo es la causa m\u00e1s com\u00fan de anemia. Con anemia, tu sangre tiene menos gl\u00f3bulos rojos de lo normal.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si tienes poco hierro, puedes sentirte d\u00e9bil o cansado, tener mareos, notar falta de aire o tener un latido con un ritmo o una velocidad fuera de lo normal. A veces el hierro bajo solo da molestias cuando ya est\u00e1 muy bajo. Por eso tu profesional de la salud tambi\u00e9n puede pedir una prueba de hierro aunque no tengas molestias.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si tienes demasiado hierro, puedes sentirte d\u00e9bil o cansado, tener dolor en las articulaciones, sobre todo en las rodillas o las manos, tener dolor de barriga, sentir menos deseo sexual o tener dificultades con la erecci\u00f3n. Tu piel tambi\u00e9n puede volverse gris, de aspecto met\u00e1lico o de color bronce.<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\">Qu\u00e9 dice tu valor de transferrina<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">La directriz del laboratorio<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Labplusarts, el laboratorio con el que trabaja BioProfile, usa para la transferrina un valor de referencia de 2,2 a 3,6 g\/l.
