Le cholécalciférol, ou vitamine D3, est la molécule que la peau produit à partir du 7-déhydrocholestérol lorsqu'elle est exposée aux rayons UVB. Dans l'organisme, elle est ensuite convertie par le foie en calcidiol, la forme de réserve mesurée lors d'une prise de sang, puis par les reins en calcitriol, la forme active. Choisir un complément de vitamine D3, c'est donc apporter à ce circuit la même matière première que celle produite naturellement.\u003c\/p\u003e\u003cp\u003eLa vitamine D contribue au fonctionnement normal du système immunitaire, au maintien d'une ossature, d'une dentition et d'une fonction musculaire normales, à l'absorption et à l'utilisation normales du calcium et du phosphore, et joue un rôle dans le processus de division cellulaire. Chez LUTO Supplements, la collection vitamine D3 réunit des gouttes, des capsules molles et des associations D3 et K2 de NOW Foods, ESN, Nuvi Health, German Elite Nutrition et LUTO Supplements.

Après ingestion, il est absorbé dans l'intestin grêle avec les graisses alimentaires, puis stocké notamment dans le tissu adipeux et le foie. Cette capacité de stockage explique pourquoi le statut en vitamine D évolue lentement, sur des semaines plutôt que sur des jours, et pourquoi la régularité de la prise compte davantage que le moment exact de la journée.\u003c\/p\u003e\u003ch3\u003ePourquoi les compléments utilisent-ils la D3 plutôt que la D2 ?\u003c\/h3\u003e\u003cp\u003eL'ergocalciférol (D2) d'origine végétale et le cholécalciférol (D3) augmentent tous deux le statut en vitamine D, mais la D3 est la forme identique à celle issue de la production cutanée et la forme standard des compléments actuels. C'est la raison pour laquelle les produits de cette collection, des gouttes NOW Foods aux gélules ESN, reposent sur le cholécalciférol.\u003c\/p\u003e\u003ch3\u003eD'où vient la vitamine D3 des compléments ?\u003c\/h3\u003e\u003cp\u003eLe cholécalciférol des compléments est le plus souvent obtenu à partir de la lanoline, la cire naturelle de la laine de mouton, transformée par exposition aux UV selon le même principe que dans la peau humaine.

La fiche de chaque produit précise l'origine et les ingrédients utilisés, comme l'huile porteuse des gouttes.\u003c\/p\u003e\u003ch3\u003eComment favoriser l'absorption de la vitamine D3 ?\u003c\/h3\u003e\u003cp\u003eLa D3 étant liposoluble, elle s'absorbe mieux au cours d'un repas contenant des matières grasses. Les capsules molles présentent l'avantage de contenir la vitamine déjà dissoute dans une base huileuse, et les gouttes utilisent une huile porteuse comme l'huile MCT. Prendre sa vitamine D3 au petit-déjeuner ou au dîner, avec un peu de graisses, est une habitude simple et efficace.\u003c\/p\u003e\u003ch3\u003eUI et microgrammes : lire les dosages\u003c\/h3\u003e\u003cp\u003eLes dosages de vitamine D s'expriment en unités internationales (UI) ou en microgrammes (µg), sachant que 40 UI correspondent à 1 µg. Un produit de 1000 UI apporte donc 25 µg, 2000 UI correspondent à 50 µg et 5000 UI à 125 µg. La limite supérieure de sécurité fixée par l'EFSA pour les adultes est de 100 µg, soit 4000 UI, par jour, toutes sources confondues.\u003c\/p\u003e\u003ch3\u003eQuel dosage de vitamine D3 choisir ?\u003c\/h3\u003e\u003cp\u003eLe bon dosage dépend de votre exposition au soleil, de votre âge et de votre situation personnelle. Pour un entretien quotidien, 1000 à 2000 UI est un choix courant. Les dosages de 5000 UI, comme les capsules molles NOW Foods ou les comprimés GEN, s'utilisent plutôt de manière non quotidienne, par exemple tous les deux ou trois jours, ou sur avis d'un professionnel de santé. Respectez la dose journalière recommandée mentionnée sur l'étiquette.\u003c\/p\u003e\u003ch3\u003eVitamine D3 et K2 MK-7 : le duo classique\u003c\/h3\u003e\u003cp\u003ePlusieurs produits associent la D3 à la vitamine K2 sous forme de ménaquinone-7 (MK-7), comme la Vitamine D3+K2 d'ESN avec 5600 UI et 200 µg de K2, le Mega D-3 \u0026amp; MK-7 de NOW Foods ou les gouttes A, D3 et K2 de Nuvi Health. Les deux vitamines se complètent : la vitamine D contribue à l'absorption normale du calcium, et la vitamine K contribue au maintien d'une ossature normale et à une coagulation sanguine normale. La forme MK-7 est appréciée pour sa longue durée de présence dans le sang.\u003c\/p\u003e\u003ch3\u003eGouttes ou capsules molles : quel format pour vous ?\u003c\/h3\u003e\u003cp\u003eLes gouttes, comme la vitamine D3 liquide de NOW Foods ou le flacon XL de Nuvi Health, permettent d'ajuster la dose goutte par goutte et conviennent aux personnes qui avalent difficilement les gélules. Les capsules molles, disponibles en grands conditionnements de 240 à 360 pièces, offrent une dose fixe et un rapport quantité-prix intéressant pour une prise au long cours.

This \u003cstrong\u003emultivitamin complex\u003c\/strong\u003e from German Elite Nutrition combines 25 vitamins and minerals in a single formula. From magnesium, calcium, and potassium to zinc, selenium, and a full group of B vitamins, plus the combination of vitamin D3 and K2. You spread the intake over four to eight capsules per day.\u003c\/p\u003e\u003ch3\u003eWhat the formula contains\u003c\/h3\u003e\u003cp\u003eThe formula contains 25 active nutrients. In addition to the known basic minerals calcium, magnesium, and potassium, it includes the trace elements zinc, iron, manganese, copper, iodine, chromium, selenium, and molybdenum. The vitamin component is at least as comprehensive: vitamin C, a full group of B vitamins (B1, B2, B3, B5, B6, biotin, folic acid, and B12), plus vitamins A, D3, E, and K2. Additionally, lutein, a plant substance derived from marigolds, has been added. This broad composition makes this multivitamin complex a general supplement to your diet, rather than an isolated high dosage of a single nutrient. Many wonder whether a multivitamin is truly beneficial alongside a normal diet. A varied diet remains the foundation; a complex like this complements it, for example during busy periods or in case of an irregular diet. Athletes and individuals with demanding schedules often consciously choose such a broad base, as their micronutrient needs may then be higher. The idea is not to treat a deficiency, but to provide comprehensive daily coverage.\u003c\/p\u003e\u003ch3\u003eActive and highly absorbable forms\u003c\/h3\u003e\u003cp\u003eWhat distinguishes this complex is the choice of biologically active and highly absorbable compounds. Magnesium and calcium are partly present as bisglycinate and lysinate, mineral forms bound to amino acids. Folate is present in its active form, L-5-methyltetrahydrofolate calcium (known as Magnafolat), vitamin K2 is all-trans menaquinone MK-7 (K2VITAL), and vitamin B12 is present as methylcobalamin. Vitamin D3 is a vegan variant. This is a deliberate choice: some cheaper multivitamins use forms like folic acid or cyanocobalamin, whereas here you get the forms your body can use directly. The supplement contains no superfluous excipients, animal-derived ingredients, or artificial additives. Active forms cost more to purchase, but the body does not need to convert them before it can use them. For those who pay attention to the quality of a multivitamin complex, this is a detail that makes a difference.\u003c\/p\u003e\u003ch3\u003eWhat the nutrients contribute to\u003c\/h3\u003e\u003cp\u003eA comprehensive formula also corresponds to the official claims of the various nutrients. Magnesium contributes to the reduction of tiredness and fatigue. Zinc and selenium contribute to the normal function of the immune system. Iron contributes to normal red blood cell and hemoglobin formation. Vitamin D and calcium contribute to the maintenance of normal bones. Iodine, copper, and manganese contribute to normal energy-yielding metabolism, and chromium contributes to the maintenance of normal blood glucose levels. Finally, potassium contributes to normal muscle function. This complex thus covers a wide range of functions with a single formula. Bones, the immune system, energy metabolism, and muscles all appear in the claims, distributed across the different nutrients. We only mention the officially authorized claims of the vitamins and minerals here; there is no authorized claim for the added lutein, so we deliberately do not mention it.\u003c\/p\u003e\u003ch3\u003eFlexible dosage, 4 to 8 capsules\u003c\/h3\u003e\u003cp\u003eThe intake is flexible: you take four to eight capsules per day, spread out and during a meal with sufficient water. At four capsules, you are at half the reference values, at eight at the full daily serving. This allows you to adapt the dosage to what you need, for example, a lower intake on calm days and the full eight during a busy or intense period, such as around a heavy training block. One pot contains 240 capsules, so at eight per day, you get thirty days. Do not exceed the maximum daily dose of eight capsules. Preferably take them with a meal, as fat-soluble vitamins A, D, E, and K are then better absorbed. If you spread the capsules throughout the day, you maintain a regular intake. In summary, this is a comprehensive multivitamin complex with 25 nutrients in active forms, with flexible dosing, as a daily base for your diet. Those who already use isolated supplements can take a multivitamin like this as a base and consciously add an isolated higher dosage, for example, additional vitamin D in winter. Make sure not to double up on the same nutrient with isolated products. As fat-soluble vitamins A, D, E, and K are accompanied by a meal, many people take the capsules at breakfast or lunch.\u003c\/p\u003e","brand":"German Elite Nutrition","offers":[{"title":"Default Title","offer_id":49386120216804,"sku":"gen-123","price":23.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/9724\/7460\/files\/AllInOneMineraal_VitamineComplexGEN.jpg?v=1783855452"},{"product_id":"gen-vitamine-d3-5000-ui-k2-200-mcg","title":"Vitamin D3 5,000 IU + K2 200 µg | 180 Tablets | GEN","description":"\u003ch2\u003eGEN Vitamin D3 and K2\u003c\/h2\u003e\n\u003cp\u003eThis GEN product combines \u003cstrong\u003evitamin D3\u003c\/strong\u003e with vitamin K2 MK-7 in one tablet. The D3 is sourced from lichen, not lanolin as in most D3 supplements. This makes it a completely plant-based variant. Per tablet, you get 5,000 IU of vitamin D3 and 200 µg of K2, making it a high-dose formula for those looking to specifically supplement their intake. This is ideal for informed consumers, vegans, or anyone who spends little time outdoors.\u003c\/p\u003e\n\u003ch3\u003eWhat D3 from lichen precisely means\u003c\/h3\u003e\n\u003cp\u003eMost vitamin D3s on the market are extracted from lanolin, a waxy substance from sheep's wool. GEN opts for an alternative source: lichen. Chemically, the result is the same cholecalciferol, but the origin is plant-based. For those following a vegan lifestyle, this is a significant difference. Your body normally produces vitamin D3 in the skin under the influence of sunlight. In autumn and winter, or if you stay indoors a lot, this production drops sharply. This is precisely why so many people turn to a supplement during the darker months. Vitamin D3 contributes to the normal absorption and utilization of calcium and phosphorus. Furthermore, vitamin D3 contributes to the normal functioning of the immune system, the maintenance of normal bones and teeth, and normal muscle function. Vitamin D also plays a role in the process of cell division. Additionally, vitamin D is necessary for normal growth and bone development in children. This wide range of functions explains why vitamin D is one of the most supplemented vitamins, especially in countries with scarce winter sun.\u003c\/p\u003e\n\u003ch3\u003eWhy K2VITAL MK-7 is added\u003c\/h3\u003e\n\u003cp\u003eWhat many people don't know: vitamin D3 and vitamin K2 work as a team. Vitamin D3 contributes to normal blood calcium concentrations. But calcium then needs to get to the right place, namely your bones. This is where vitamin K2 comes in. Vitamin K contributes to the maintenance of normal bones and normal blood clotting. MK-7 (menaquinone-7) is the form of K2 that your body retains longest in the bloodstream. The K2 in this tablet is K2VITAL®, a standardized raw material with 99.7% all-trans MK-7. This all-trans form is relevant because your body retains it better and longer than the cis form. The half-life of MK-7 is also longer than that of K1 or MK-4, resulting in more stable levels in the blood. Thus, the two vitamins complement each other in one tablet.\u003c\/p\u003e\n\u003ch3\u003e5,000 IU Vitamin D3 per tablet\u003c\/h3\u003e\n\n\u003cp\u003eWith 5,000 IU of vitamin D3 per tablet, you are well above the usual maintenance dose of 400 to 1,000 IU per day. This is a deliberate choice. The recommended use is indeed one tablet every five days. This way, you spread the high dose over a longer period, instead of taking it daily. The 200 µg of K2 per tablet corresponds to the amount often used in clinical studies. Both vitamins are fat-soluble. This means your body absorbs them better when you take them with a meal containing some fat. An avocado toast or a handful of nuts is already sufficient. Many wonder if 5,000 IU is not too much; by taking the dose only once every five days, the average daily intake remains limited. If you want to know exactly where you stand, you can have your vitamin D levels measured by a blood test at the doctor and adjust your intake accordingly.\u003c\/p\u003e\n\u003ch3\u003eA short, plant-based composition\u003c\/h3\u003e\n\n\u003cp\u003eThe tablet has a short ingredient list. Besides vitamin D3 and K2, it only contains microcrystalline cellulose as a filler and stearic acid, nothing more. No gelatin, no shellac, no animal-derived additives. The entire formula is vegan and laboratory-tested. A jar contains 180 tablets. At one tablet every five days, you have enough for over nine months, which is convenient if you don't want to reorder constantly. Thus, with this D3 from lichen, combined with K2VITAL®, you maintain clear and fully plant-based supplementation.

Biotin is present at 5000 mcg, which is 100 times the reference intake. This is no coincidence. Biotin, also known as vitamin B7 or B8, is the substance found in almost all hair and nail supplements. Biotin contributes to the maintenance of normal hair and normal skin. In your cells, biotin acts as a cofactor for enzymes involved in fatty acid production and amino acid processing. These processes are directly related to keratin, the protein that makes up your hair and nails. What many people don't know: high doses of biotin can skew laboratory test results, especially thyroid values and cardiac markers. Inform your doctor if you are taking it when you have a blood test.\u003c\/p\u003e\n\u003ch3\u003eFour vitamins for the maintenance of normal skin\u003c\/h3\u003e\n\u003cp\u003eThe gummy contains 722 mcg of vitamin A per daily dose. Vitamin A contributes to the maintenance of normal skin and normal mucous membranes. In addition, vitamin A contributes to the normal function of the immune system and the maintenance of normal vision. Vitamin C is present at 20 mg. Vitamin C contributes to normal collagen formation for the normal function of the skin. Collagen is the protein that keeps your skin firm and supple. Vitamin C also helps protect cells from oxidative stress. Vitamin D3 (10 mcg per daily dose) contributes to the maintenance of normal bones and the normal function of the immune system. Vitamin E (11 mg) also helps protect cells from oxidative stress. Together, they form a quartet that approaches the skin from different angles.\u003c\/p\u003e\n\u003ch3\u003eB vitamins with iodine and zinc for a broader perspective\u003c\/h3\u003e\n\u003cp\u003eIn addition to biotin, the formula contains four other B vitamins: B6 (2 mg), folic acid (260 mcg), B12 (6 mcg), and B5, or pantothenic acid (5.2 mg). Folic acid plays a role in the process of cell division, which is relevant for continuously renewing tissues such as hair follicles and skin. Vitamin B12 contributes to the reduction of fatigue. Vitamin B5 contributes to normal energy metabolism. What makes this product broader than a standard hair and nail supplement: the addition of iodine (42 mcg) and zinc (2.7 mg). Iodine contributes to the maintenance of normal skin. Zinc contributes to the maintenance of normal hair, normal nails, and normal skin. In this respect, zinc is the broadest claim carrier in the entire formula.\u003c\/p\u003e\n\u003ch3\u003eCholine and inositol: the building blocks no one talks about\u003c\/h3\u003e\n\u003cp\u003eFinally, it contains 40 mcg of choline and 40 mcg of inositol. Both are substances naturally present in your body and involved in cell membranes. Choline contributes to the maintenance of normal liver function and normal homocysteine metabolism. Inositol currently has no recognized health claims by the EU, but it is often added to cosmetic supplements because it is related to B vitamins. Together, choline and inositol add a little more depth to the formula, without claiming the main role.\u003c\/p\u003e\n\u003ch3\u003eWhy a gummy rather than a capsule\u003c\/h3\u003e\n\u003cp\u003eIn terms of absorption, the form makes no difference. Your body processes vitamins the same way, whether they come from a gummy, a capsule, or a tablet. The practical advantage lies in regularity. An orange-flavored gummy feels less like a supplement and more like something you naturally take. For substances like vitamin C, which your body does not store, regular daily intake is more important than a one-time high dose. The jar contains 60 gummies and therefore covers 30 days at two per day.\u003c\/p\u003e","brand":"LUTO Supplements","offers":[{"title":"Default Title","offer_id":49390690205924,"sku":"8721055250517","price":19.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/9724\/7460\/files\/19308972-8c4b-453c-b2ed-8b20b79982f3.jpg?v=1783929134"},{"product_id":"now-vitamine-d3-1000-ui-25-mcg-360-capsules-molles-now-foods","title":"Vitamin D3 1000 IU | 25 mcg | 360 Softgels | NOW Foods","description":"\u003ch2\u003eNOW Foods Vitamin D3 1000 IU\u003c\/h2\u003e\n\u003cp\u003eLooking for a simple daily vitamin D?

D3 is the most common form used in supplements. On labels, vitamin D is expressed in micrograms (µg) or international units (IU), with 1 microgram being equivalent to 40 IU. The 25 µg in this softgel therefore corresponds to 1000 IU, a very common daily amount. Vitamin D is one of the few vitamins for which diet alone is often not enough: fatty fish, eggs, and fortified products provide some, but the majority normally comes from sunlight.

In a country like the Netherlands, with long, dark winters, this is why authorities recommend extra vitamin D for certain groups and why many people supplement it year-round.\u003c\/p\u003e\n\u003ch3\u003eWhat Vitamin D Contributes To\u003c\/h3\u003e\n\u003cp\u003eVitamin D contributes to the normal functioning of the immune system and the maintenance of normal bones, normal teeth, and normal muscle function. Vitamin D also contributes to the normal absorption and utilization of calcium and phosphorus and to normal blood calcium levels. Vitamin D also plays a role in the process of cell division. The full list of approved health claims can be found further down this page. The 2000 IU per softgel makes this vitamin D3 a slightly more potent supplement than a standard 1000 IU.\u003c\/p\u003e\n\u003ch3\u003eSoftgel with Oil as a Carrier\u003c\/h3\u003e\n\u003cp\u003eSince vitamin D is fat-soluble, this vitamin D3 is supplied in a softgel containing oil: in this case, a base of extra virgin olive oil and safflower oil. This fatty base matches the fat-soluble nature of the vitamin. The softgel is small and easy to swallow. An oily base has the advantage that the fat-soluble vitamin is already dissolved in a fatty substance, which corresponds to how the body absorbs vitamin D from food. As the capsule contains gelatin, this product is not suitable for vegetarians or vegans.\u003c\/p\u003e\n\u003ch3\u003eA Large Bottle of 240 Softgels\u003c\/h3\u003e\n\u003cp\u003eOne bottle contains 240 softgels, a generous supply that lasts a long time. This is a straightforward product: only vitamin D3 in an oily base, without blends or other additions. This 2000 IU variant is, in terms of dosage, between the entry-level 1000 IU variant and the high-dose 5000 IU variant, and is a good choice for those who want to supplement a bit more broadly without immediately opting for the highest dosage. In summary: a practical, medium-dose vitamin D3 from a reputable brand known for its clear labels and controlled production.\u003c\/p\u003e","brand":"NOW Foods","offers":[{"title":"Default Title","offer_id":49392691347684,"sku":"0733739003775","price":15.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/9724\/7460\/files\/HogeSterkteVitanimeD3NOW2000IU240Softgels.jpg?v=1783952157"},{"product_id":"now-mega-d-3-mk-7-5000-ui-d3-180-g-k2-60-vcaps-now-foods","title":"Mega D-3 \u0026 MK-7 | 5000 IU D3 + 180µg K2 | 60 Veg Capsules | NOW Foods","description":"\u003ch2\u003eNOW Foods Mega D-3 \u0026amp; MK-7\u003c\/h2\u003e\n\u003cp\u003eLooking for a high-dose \u003cstrong\u003eVitamin D3 and Vitamin K2\u003c\/strong\u003e in one capsule?

One jar contains 60 vegetable capsules.\u003c\/p\u003e\n\u003ch3\u003eWhy D3 and K2 are often combined\u003c\/h3\u003e\n\u003cp\u003eVitamin D3 and Vitamin K2 are both fat-soluble and are often offered together in one product for this reason. Vitamin D3 is cholecalciferol, the form your skin produces itself under the influence of sunlight, which is harder to keep at a good level in winter. Vitamin K2 is a lesser-known vitamin, but present in food. In this formula, you get vitamin D3 and K2 in a fixed ratio, so you don't have to combine two separate products. Vitamin D is known as the sunshine vitamin, because your skin produces it itself under the influence of sunlight; it is precisely during the darker months that this works less well. This explains why many people supplement their vitamin D intake all year round, and why a combined D3-K2 formula is popular.\u003c\/p\u003e\n\u003ch3\u003eWhat D3 and K2 contribute to\u003c\/h3\u003e\n\u003cp\u003eVitamin D contributes to the maintenance of normal bones and the normal functioning of the immune system, and plays a role in the absorption and utilization of calcium. Vitamin K contributes to normal blood clotting and the maintenance of normal bones. Both vitamins therefore contribute, among other things, to the maintenance of normal bones. The two vitamins thus complement each other in this product. The full list of approved health claims for these two vitamins can be found further down this page, along with the safety information.\u003c\/p\u003e\n\u003ch3\u003eVitamin K2 in the form of MK-7 from MenaQ7®\u003c\/h3\u003e\n\u003cp\u003eThe vitamin K2 in this product is menaquinone-7, abbreviated MK-7, derived from the branded ingredient MenaQ7®. MK-7 is one of the most commonly used forms of vitamin K2 in dietary supplements and is recognized as a well-absorbed variant. MenaQ7® is one of the most well-known branded ingredients for this form of K2. Each capsule contains 180 µg of K2, in addition to 125 µg of vitamin D3. This makes it a high-dose combination of vitamin D3 and K2 in one vegetable hypromellose capsule. The ratio between a high dose of D3 and a generous amount of K2 is deliberately chosen, so that both fat-soluble vitamins are taken together in one go. \u003c\/p\u003e\n\u003ch3\u003e60 vegetable capsules\u003c\/h3\u003e\n\u003cp\u003eOne jar contains 60 Vcaps, which is two months of daily use. The ingredient list is clear: the two vitamins, a vegetable hypromellose shell and a few functional excipients such as rice flour and silicon dioxide, without any other superfluity. Due to the high dosage and the presence of vitamin K, the safety information on this page is important; read it carefully, especially if you are taking blood thinners. Since both vitamins are present in a fixed quantity in a single capsule, you do not need to buy them separately or combine them yourself. This makes it a clear choice for those who deliberately opt for the combination of these two fat-soluble vitamins.

An oily base has the advantage that the fat-soluble vitamin is already dissolved in fat, which corresponds to how the body absorbs vitamin D from food.
