Elle est hydrosoluble, ce qui signifie que le corps n'en constitue pratiquement pas de réserves et qu'un apport régulier via l'alimentation est nécessaire. La thiamine joue un rôle de cofacteur dans la transformation des glucides en énergie et contribue à un métabolisme énergétique normal, au fonctionnement normal du système nerveux, à des fonctions psychologiques normales et à une fonction cardiaque normale.\u003c\/p\u003e\u003cp\u003eChez LUTO Supplements, vous trouverez la vitamine B1 sous deux formes : les comprimés Vitamine B-1 100 mg de NOW Foods, pour un apport ciblé de thiamine, et le Complexe Minéraux et Vitamines Tout-en-Un de German Elite Nutrition, qui associe la thiamine à un large éventail d'autres micronutriments. Sur cette page, vous découvrez ce qu'est la vitamine B1, où la trouver et comment choisir le produit adapté.\u003c\/p\u003e\u003ch3\u003eQu'est-ce que la vitamine B1 ?\u003c\/h3\u003e\u003cp\u003eLa thiamine a été la première vitamine du groupe B à être identifiée, d'où son nom de vitamine B1. Dans le corps, elle est convertie en thiamine pyrophosphate, une coenzyme indispensable à plusieurs réactions du métabolisme des glucides. Comme les réserves corporelles sont limitées, l'apport doit être renouvelé régulièrement via l'alimentation ou, si nécessaire, un complément.\u003c\/p\u003e\u003ch3\u003eÀ quoi contribue la thiamine ?\u003c\/h3\u003e\u003cp\u003eLes allégations de santé suivantes sont autorisées par l'Union européenne pour la vitamine B1 : la thiamine contribue à un métabolisme énergétique normal, au fonctionnement normal du système nerveux, à des fonctions psychologiques normales et à une fonction cardiaque normale. Ces contributions expliquent pourquoi la thiamine occupe une place centrale dans de nombreux complexes de vitamines B et multivitamines.\u003c\/p\u003e\u003ch3\u003eDans quels aliments trouve-t-on la vitamine B1 ?\u003c\/h3\u003e\u003cp\u003eLes bonnes sources de thiamine sont les céréales complètes, la viande de porc, les légumineuses, les fruits à coque, les graines et les pommes de terre. Le raffinage des céréales fait perdre une partie importante de la thiamine, raison pour laquelle les produits complets sont de meilleures sources que les variantes raffinées. Une alimentation variée couvre en principe les besoins quotidiens.\u003c\/p\u003e\u003ch3\u003eQuand un complément de vitamine B1 est-il utile ?\u003c\/h3\u003e\u003cp\u003eUn complément peut être utile lorsque l'alimentation est irrégulière ou peu variée, en période d'activité physique intense avec un apport élevé en glucides, ou lorsque les besoins augmentent. Les personnes qui consomment peu de produits céréaliers complets peuvent également avoir un apport plus faible que souhaité. En cas de doute sur votre statut, demandez conseil à un professionnel de santé.\u003c\/p\u003e\u003ch3\u003eQuelle quantité de vitamine B1 par jour ?\u003c\/h3\u003e\u003cp\u003eLa valeur nutritionnelle de référence européenne pour la thiamine est de 1,1 mg par jour. Les compléments sont souvent dosés plus haut, comme les comprimés de 100 mg de NOW Foods. La thiamine étant hydrosoluble, l'excédent est en grande partie éliminé par les urines. Respectez la dose journalière recommandée indiquée sur l'étiquette.\u003c\/p\u003e\u003ch3\u003eComprimé isolé ou complexe complet ?\u003c\/h3\u003e\u003cp\u003eLe choix dépend de votre objectif. Si vous recherchez un apport ciblé de thiamine, un comprimé mono-ingrédient comme la Vitamine B-1 de NOW Foods est le plus logique. Si vous préférez couvrir un large éventail de vitamines et de minéraux en une seule prise, le Complexe Tout-en-Un de German Elite Nutrition, qui contient la thiamine aux côtés d'autres micronutriments, est une option pratique.\u003c\/p\u003e\u003ch3\u003eQuel est le meilleur moment pour prendre la vitamine B1 ?\u003c\/h3\u003e\u003cp\u003eLa vitamine B1 peut se prendre à tout moment de la journée, de préférence au cours d'un repas pour un meilleur confort digestif. Comme pour la plupart des micronutriments, la régularité de la prise compte davantage que l'heure exacte.\u003c\/p\u003e\u003ch3\u003eBon à savoir\u003c\/h3\u003e\u003cp\u003eAux doses recommandées, la vitamine B1 convient à un usage quotidien. Un complément alimentaire ne remplace pas une alimentation variée et équilibrée ni un mode de vie sain. En cas de traitement médical, de grossesse ou d'allaitement, demandez conseil à un professionnel de santé avant de commencer une supplémentation.\u003c\/p\u003e","products":[{"product_id":"gen-complexe-mineraux-vitamines-tout-en-un-240-gelules","title":"All-in-One Minerals \u0026 Vitamins Complex | 240 Capsules | German Elite Nutrition","description":"\u003ch2\u003eGEN All-in-One Mineral \u0026amp; Vitamin Complex\u003c\/h2\u003e\u003cp\u003eAre you looking for a daily base rather than ten separate pots? 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":"now-vitamine-b-1-100-mg-100-comprimes-now-foods","title":"Vitamin B-1 100 mg | 100 Tablets | NOW Foods","description":"\u003ch2\u003eVitamin B-1 100 mg from NOW Foods\u003c\/h2\u003e\n\u003cp\u003eLooking to specifically supplement your B1 intake? This \u003cstrong\u003evitamin B1\u003c\/strong\u003e from NOW Foods contains 100 mg of thiamine per tablet, in the form of thiamine HCl. It's a simple formula with a single active ingredient and a fixed dosage per tablet. One bottle contains 100 tablets, which, at one per day, lasts for a little over three months.\u003c\/p\u003e\n\u003ch3\u003eWhat is Vitamin B1?\u003c\/h3\u003e\n\u003cp\u003eVitamin B1, better known as thiamine, is one of the eight B vitamins and a water-soluble vitamin. Historically, it was the first B vitamin discovered, which explains the 1 in its name. In food, thiamine is found in whole grains, legumes, pork, nuts, and seeds, among others. Since it's water-soluble, the body stores very little thiamine, and some is lost in cooking water during preparation. This is precisely why regular intake through diet or a supplement is important: your body doesn't build up large reserves. A supplement containing vitamin B1 is a way to supplement this vitamin specifically and in a fixed amount, independently of a broad complex. In the body, thiamine acts as a cofactor: a small helper molecule that certain enzymes need to perform their work, particularly in carbohydrate conversion. This explains why thiamine plays a role in virtually every cell in the body, and why it was one of the first vitamins whose importance was scientifically demonstrated.\u003c\/p\u003e\n\u003ch3\u003eWhat does thiamine contribute to?\u003c\/h3\u003e\n\u003cp\u003eVitamin B1 contributes to normal energy metabolism and the normal functioning of the nervous system. Thiamine also contributes to normal psychological function and normal heart function. These are the approved health claims for thiamine, which you can also find in the overview further down this page. They explain why vitamin B1 is an isolated B vitamin often chosen by those who are not looking for a broad B complex.\u003c\/p\u003e\n\u003ch3\u003eA simple, high-dose formula\u003c\/h3\u003e\n\u003cp\u003eAt 100 mg per tablet, this vitamin B1 is well above the reference intake; the table on the label also shows this. It's a deliberately stripped-down formula: thiamine HCl as the sole active ingredient, supplemented with a few functional excipients such as microcrystalline cellulose and vegetable stearic acid. It contains no broad B-complex mixtures, nor other vitamins or minerals. This allows for precise supplementation of this single vitamin and the ability to decide what to combine it with. For those already using a broad B complex or a multivitamin, it is advisable to check the total intake of B vitamins.\u003c\/p\u003e\n\u003ch3\u003eWho is this B1 suitable for?\u003c\/h3\u003e\n\u003cp\u003eThis vitamin B1 is for those who want to supplement thiamine alone, in a fixed amount per tablet and without unnecessary extras. You get thiamine and nothing else significant, in a fixed, easy-to-track amount. Isolated thiamine is often chosen by people who want to specifically supplement this vitamin without the rest of a B complex, or who want to adapt their intake to their own diet. In short: a simple, high-dose B1 formula from a brand known for its clear labels and controlled production.\u003c\/p\u003e","brand":"NOW Foods","offers":[{"title":"Default Title","offer_id":49392693215460,"sku":"0733739004468","price":10.9,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/9724\/7460\/files\/B1NOW.jpg?v=1783952369"}],"url":"https:\/\/www.luto-supplements.fr\/en\/collections\/vitamine-b1-thiamine.oembed","provider":"LUTO Supplements France","version":"1.0","type":"link"}
