The bottle contains 60 capsules, which is two months at one capsule a day.\u003c\/p\u003e\n\u003cp\u003eThe formula is pared back to the strict essentials: maltodextrin as a bulking agent, the two vitamins, and a hydroxypropyl methylcellulose shell. The latter is of plant origin, which sets this product apart from most vitamin D products on the market, often sold as bovine gelatine softgels.\u003c\/p\u003e\n\u003cp\u003ePairing D3 with K2 has become a standard in the \u003ca href=\"\/en\/collections\/vitamine-d\"\u003evitamin D\u003c\/a\u003e aisle, and the logic behind it is simple: vitamin D increases calcium absorption, vitamin K plays a part in its use in bone. Both carry authorised claims relating to bones, and that is what justifies bringing them together.

NRV within the meaning of Regulation 1169\/2011: 5 µg for vitamin D, 75 µg for vitamin K. The percentages above are calculated from these values, as the manufacturer does not publish them in the data provided.\u003c\/p\u003e\n\u003cp\u003eLet us start with vitamin D, and say things as they are. \u003cstrong\u003e50 µg per capsule is ten times the nutrient reference value.\u003c\/strong\u003e The figure looks striking, but there is an explanation for it: the European NRV of 5 µg is a very low floor, and the \u003cstrong\u003eEFSA sets 100 µg a day as the tolerable upper intake level\u003c\/strong\u003e in adults. One capsule therefore represents half that ceiling — a straightforward dose, common on this type of product, and one that stays within bounds provided you do not stack sources.\u003c\/p\u003e\n\u003cp\u003eThat is precisely the point to watch. If you already take a \u003ca href=\"\/en\/collections\/multivitamines\"\u003emultivitamin\u003c\/a\u003e, cod liver oil or a bone complex, add up the micrograms before adding this capsule. Vitamin D is fat-soluble: it is stored in the body, unlike vitamin C.\u003c\/p\u003e\n\u003cp\u003eThe authorised claims are precise, and they are more than enough on their own: \u003cstrong\u003evitamin D contributes to the maintenance of normal bones, to the maintenance of normal muscle function, to the normal function of the immune system, and to the normal absorption and utilisation of calcium and phosphorus.\u003c\/strong\u003e As for the second: \u003cstrong\u003evitamin K contributes to normal blood clotting and to the maintenance of normal bones.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOn the MK-7 form, a word of honesty. It is a long-chain menaquinone, known for staying in the body longer than MK-4. We will stop there: claiming a quantified superiority would require a source we do not have, and 200 µg is a high dose for this vitamin — which is also what makes the warning about anticoagulants so important.\u003c\/p\u003e\n\n\u003ch2\u003eHow should you take Vit D3 K2?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDose:\u003c\/strong\u003e 1 capsule. \u003cstrong\u003eLiquid:\u003c\/strong\u003e a large glass of water. \u003cstrong\u003eTiming:\u003c\/strong\u003e during a meal containing fat, preferably in the morning or at midday. \u003cstrong\u003eFrequency:\u003c\/strong\u003e one serving a day. \u003cstrong\u003eDuration:\u003c\/strong\u003e continuous use is possible, particularly during periods of low sunlight.\u003c\/p\u003e\n\u003cp\u003eThe fatty meal is not a detail. D3 and K2 are both fat-soluble: swallowed on an empty stomach with a glass of water, part of the intake is lost. A breakfast with eggs, a few almonds, a drizzle of oil or simply a full-fat yoghurt is enough to change that. It is the most rewarding move on this whole page.\u003c\/p\u003e\n\u003cp\u003eOn the time of year, the manufacturer is right to insist: it is \u003cstrong\u003efrom October to April\u003c\/strong\u003e that the question really arises in France. Winter sunshine does not allow synthesis in the skin, and that is where the 60-capsule bottle makes sense — two months, to be repeated two or three times over the cold season.\u003c\/p\u003e\n\u003cp\u003eTwo useful combinations to know about. \u003ca href=\"\/en\/collections\/magnesium\"\u003eMagnesium\u003c\/a\u003e is involved in vitamin D metabolism, and a proper calcium intake from food — dairy products, green vegetables, mineral waters — makes more sense than the capsule taken on its own. \u003ca href=\"\/en\/collections\/zinc\"\u003eZinc\u003c\/a\u003e, for its part, can be taken at another time of day without interference.\u003c\/p\u003e\n\n\u003ch2\u003eWho is this product for, and who is it not for?\u003c\/h2\u003e\n\u003cp\u003eIt suits adults living in a country with little winter sunshine, those who work indoors, people with darker skin who synthesise less vitamin D, and indoor athletes. As the capsule is plant-based, it is suitable for vegetarians; note, however, that vitamin D3 is most often of animal origin, and the manufacturer does not specify its source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIt is not advised for people on anticoagulant treatment\u003c\/strong\u003e — warfarin, vitamin K antagonists — without prior medical advice. This is not a token precaution: vitamin K is directly involved in clotting, and these treatments act on precisely that pathway. If this concerns you, speak to your doctor before opening the bottle, not afterwards.\u003c\/p\u003e\n\u003cp\u003eThe manufacturer also states that it is \u003cstrong\u003enot suitable for pregnant or breastfeeding women, or for children\u003c\/strong\u003e, or for people on medical treatment without supervision. \u003cstrong\u003eTraces of GLUTEN (wheat, oats), NUTS, PEANUTS, EGGS, MILK, SULPHITES, FISH and SOYA\u003c\/strong\u003e are possible.\u003c\/p\u003e\n\u003cp\u003eWhat you should not expect from it. It is not a stimulant: you will feel nothing, and that is normal. Nor is it a product to take blindly over several years — vitamin D status can be measured in a laboratory, and if you supplement all year round, a blood test is the right way to know where you stand. Lastly, it is not a performance product: correcting a low status restores normal muscle function, it does not create extra strength in someone whose status is already adequate.\u003c\/p\u003e\n\n\u003ch2\u003eVitamin D3 K2 or a multivitamin?\u003c\/h2\u003e\n\u003cp\u003eThis is the choice that faces more or less everyone in autumn, and it is settled on the dose.\u003c\/p\u003e\n\u003cp\u003eA \u003ca href=\"\/en\/collections\/multivitamines\"\u003emultivitamin\u003c\/a\u003e provides vitamin D, but rarely more than 5 to 25 µg, among twenty other nutrients. It is the better choice if your diet is irregular and you want broad cover without having to think about it: B vitamins, vitamin C, trace elements, everything is covered by a single capsule. Its weakness on this particular point: the vitamin D dose is often too low to count for much in the depths of winter, and vitamin K is almost always absent from it.\u003c\/p\u003e\n\u003cp\u003eVit D3 K2 does the opposite: two vitamins, at a straightforward dose, nothing else. It is the better choice if your need has been identified — a low blood test, a winter without sun, an indoor job — and if you want to manage that one line precisely. It is also the only one of the two that provides K2, which is absent from very nearly every multivitamin.\u003c\/p\u003e\n\u003cp\u003eThe trap to avoid is always the same: taking both without counting. A multivitamin at 25 µg plus this capsule at 50 µg is 75 µg a day, still under the ceiling of 100 µg, but adding a fortified \u003ca href=\"\/en\/collections\/omega-3\"\u003efish\u003c\/a\u003e oil would tip the total over. Do the sum once and it will serve you all winter.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eIs 2,000 IU a day too much?\u003c\/h3\u003e\n\u003cp\u003eThat is 50 µg, half the tolerable upper intake level of 100 µg a day set by the EFSA in adults. It is a high dose relative to the European reference value, which is only 5 µg, but it stays within bounds as long as you do not combine several sources. The only way the question is really settled is with a blood test.\u003c\/p\u003e\n\u003ch3\u003eWhy combine K2 with D3?\u003c\/h3\u003e\n\u003cp\u003eBecause both vitamins carry an authorised claim on the maintenance of normal bones, and they act at different stages: D promotes calcium absorption, K plays a part in its use. That is the logic of the combination, and it is sound. We will not go beyond what the authorised wordings allow us to state.\u003c\/p\u003e\n\u003ch3\u003eShould it be taken in the morning or in the evening?\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer advises the morning or midday, with a meal containing fat. What matters is the fatty meal, not the hour: these are two fat-soluble vitamins, and taking them on an empty stomach appreciably reduces absorption. Choose the meal at which you eat the least lightly.\u003c\/p\u003e\n\u003ch3\u003eCan it be taken with an anticoagulant?\u003c\/h3\u003e\n\u003cp\u003eNot without medical advice. That is the manufacturer's explicit warning, and it concerns vitamin K, which is involved in blood clotting — the very pathway on which vitamin K antagonists act. This question is one for your doctor, who alone knows your treatment and how well balanced it is.\u003c\/p\u003e\n\u003ch3\u003eHow long does a bottle last?\u003c\/h3\u003e\n\u003cp\u003eTwo months, at the rate of one capsule a day for 60 capsules. Over a winter season from October to April, allow three bottles to cover the full period. It is the format that best matches seasonal use rather than continuous supplementation.\u003c\/p\u003e\n\u003ch3\u003eIs the capsule suitable for vegetarians?\u003c\/h3\u003e\n\u003cp\u003eThe shell, yes: it is made of hydroxypropyl methylcellulose, a modified cellulose of plant origin. The manufacturer does not, however, specify the origin of the vitamin D3 itself, which is most often derived from lanolin commercially. If this point is decisive for you, check with the brand before buying.\u003c\/p\u003e\n\u003ch3\u003eCan it be taken all year round?\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer allows it and recommends it above all during periods of low sun exposure. Our position is more cautious: with a continuous intake of 50 µg a day for twelve months, a vitamin D blood test is the only serious way to know whether you are at the right level. In summer, sun exposure is often enough.\u003c\/p\u003e\n\n\u003ch2\u003eWhere can you buy IO Genix Vit D3 K2?\u003c\/h2\u003e\n\u003cp\u003eThe 60-capsule bottle can be ordered from this page, and we ship throughout France and Europe. It is one of the least expensive products in the aisle, and one of the few whose usefulness in winter is beyond argument at our latitudes.\u003c\/p\u003e\n\u003cp\u003eAt the counter in Vendargues, about ten minutes from Montpellier, the question we always ask about this product comes down to three words: what else are you taking?
