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.

Es una de las pocas vitaminas que el cuerpo puede fabricar por s\u00ed mismo: la piel la produce gracias a la luz del sol. Adem\u00e1s, tambi\u00e9n obtienes vitamina D a trav\u00e9s de lo que comes.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En el h\u00edgado, la vitamina D se transforma en 25-hidroxivitamina D, o 25-OH para abreviar. Esta forma no es activa en el cuerpo, pero s\u00ed se usa en un an\u00e1lisis de sangre para determinar si hay falta de vitamina D. Despu\u00e9s, en los ri\u00f1ones, la 25-hidroxivitamina D se transforma en 1,25-dihidroxivitamina D, la forma activa.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En los alimentos, la vitamina D aparece de dos formas: ergocalciferol (vitamina D2) y colecalciferol (vitamina D3). La vitamina D2 se forma en ciertas setas y hongos, y la vitamina D3 en la piel de las personas y los animales. Las dos formas son activas, aunque la vitamina D3 tiene un efecto algo m\u00e1s fuerte.<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 la vitamina D<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">La vitamina D hace que el calcio y el f\u00f3sforo de lo que comes se absorban bien y se fijen en los huesos y los dientes durante el crecimiento. As\u00ed, la vitamina D contribuye a tener unos huesos y dientes fuertes.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La vitamina D es necesaria para limitar al m\u00e1ximo la p\u00e9rdida de calcio de los huesos y reducir as\u00ed el riesgo de sufrir una enfermedad \u00f3sea en edades m\u00e1s avanzadas. Adem\u00e1s, la vitamina D desempe\u00f1a un papel importante en el mantenimiento de una buena funci\u00f3n muscular y es importante para el buen funcionamiento del sistema inmunitario.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No todo est\u00e1 demostrado.

En 2024 se public\u00f3 en el Journal of Clinical Endocrinology and Metabolism una correcci\u00f3n de la gu\u00eda cl\u00ednica de la Endocrine Society sobre la deficiencia de vitamina D.<sup>[3]<\/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 nivel de vitamina D<\/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 vitamina D (25-OH) un valor de referencia de 50 a 150 nmol\/l.

Lista del 24 de septiembre de 2026.<sup>[4]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vitamina D demasiado baja<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Un valor bajo puede indicar una falta de vitamina D, porque la 25-hidroxivitamina D es precisamente lo que se usa en un an\u00e1lisis de sangre para determinarlo. La luz del sol es la fuente principal, y en los meses de invierno el sol en los Pa\u00edses Bajos est\u00e1 demasiado bajo para fabricar vitamina D. A los ni\u00f1os peque\u00f1os, las personas mayores, las embarazadas, las personas de piel oscura y quienes salen poco al aire libre se les aconseja tomar un suplemento de vitamina D.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vitamina D demasiado alta<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Tambi\u00e9n hay un l\u00edmite por arriba. Para los productos a los que en los Pa\u00edses Bajos se les a\u00f1ade vitamina D rige un m\u00e1ximo de 4,5 microgramos por cada 100 kilocalor\u00edas, para que la ingesta no sea demasiado alta. Para un suplemento, el Voedingscentrum mantiene la cantidad diaria recomendada de 10 microgramos al d\u00eda.<sup>[1]<\/sup><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">BioProfile est\u00e1 trabajando en sus propias zonas para cada valor, de riesgo a \u00f3ptimo. Un m\u00e9dico valora esas zonas antes de que aparezcan en tu resultado.<\/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-wat-het-beinvloedt\">Qu\u00e9 influye en tu vitamina D (25-OH)<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">La luz del sol y la estaci\u00f3n del a\u00f1o<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La mayor parte de la vitamina D la fabricas t\u00fa en la piel, gracias a la luz del sol. Se aconseja estar al aire libre cada d\u00eda de marzo a octubre, ambos incluidos, entre las 11.00 y las 15.00, de un cuarto de hora a media hora, con la cara y las manos descubiertas. En los meses de invierno el sol en los Pa\u00edses Bajos est\u00e1 demasiado bajo para fabricar vitamina D, y usas la reserva que has ido acumulando.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Lo que comes<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La vitamina D est\u00e1 presente de forma natural en el pescado azul, como el arenque y el salm\u00f3n. La carne y los huevos tambi\u00e9n contienen vitamina D, pero menos que el pescado azul. En los Pa\u00edses Bajos se a\u00f1ade vitamina D a la margarina baja en grasa, a la margarina y a las grasas para hornear y fre\u00edr, pero no al aceite. Un trozo de trucha de 100 gramos aporta 9,4 microgramos y un huevo cocido de 50 gramos, 0,9 microgramos.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">La grasa de tus comidas y las reservas de tu cuerpo<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">La vitamina D se absorbe mejor en el intestino cuando tambi\u00e9n hay grasa o aceite. Se calcula que, de media, se absorbe un 80% de la vitamina D de los alimentos. El cuerpo puede almacenar vitamina D en el tejido graso y en \u00f3rganos como el h\u00edgado.<sup>[1]<\/sup><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tu piel, tu edad y cu\u00e1nto sales al aire libre<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Cuanta m\u00e1s piel dejes al descubierto, m\u00e1s r\u00e1pido fabricas vitamina D, y cuanto m\u00e1s tiempo pases fuera, m\u00e1s fabrica tambi\u00e9n tu piel.
