Navigator Vitamin D3 10,000 IU + K2 MK-7 200 µg - 240 capsules

This is a backup version of the same Navigator formula: 240 capsules in a 250 ml bottle. The composition is identical to that in smaller packages: in one capsule, the manufacturer declares 250 µg of cholecalciferol, which is 10,000 IU of vitamin D3, and 200 µg of vitamin K2 in the MK-7 form. Cholecalciferol is derived from lanolin, which is fat from sheep's wool, and menaquinone-7 is produced through the fermentation of natto by Bacillus subtilis bacteria. The capsule is filled with three rice raw materials: concentrate, extract, and gluten-free rice flour, and the coating is made of hydroxypropyl methylcellulose, a plant-based material without gelatin. The manufacturer declares the absence of sugar, lactose, gluten, starch, wheat, corn, and magnesium stearate. With such a number of capsules, storage conditions matter more than with a small package, as the bottle stays in the cupboard longer - the manufacturer recommends a cool, dry place, out of reach of children. The capsule should be swallowed whole, with water, and the bottle itself should be kept tightly closed.

Ingredients

Content declared by the manufacturer in one capsule:

Witamina D3 (cholekalcyferol z lanoliny) - 250 µg, czyli 10 000 IU (5000% RWS)
Witamina K2 MK-7 (menachinon-7 z fermentacji natto bakteriami Bacillus subtilis) - 200 µg (267% RWS)
Fillers: rice concentrate, rice extract, gluten-free rice flour
Capsule coating: hydroxypropyl methylcellulose

The ingredient list is short, so it's worth pausing to consider the origin of both active ingredients. The manufacturer obtains cholecalciferol from lanolin, a waxy secretion from sheep glands, recovered during shearing. This is an animal-derived raw material, although it does not require slaughter. Menaquinone-7 comes from fermentation: Bacillus subtilis bacteria process soybeans into natto, from which vitamin K2 in the MK-7 form is obtained. The other three items are fillers and are a conscious choice here: instead of typical anti-caking agents, the manufacturer used concentrate, extract, and rice flour, and explicitly declares the absence of magnesium stearate. The coating made of hydroxypropyl methylcellulose is a standard substitute for gelatin in hard capsules. The list closes with six items: two vitamins, three rice raw materials, and the coating. For clarity, one explanation: the percentages given for both vitamins are reference intake values for adults, meaning they refer to daily requirements, not to the amount of the product - the manufacturer states this explicitly under the table.

Who is it for

This is a choice for adults who have been using this formula for a while and prefer to buy less frequently, in larger quantities. The 250 ml bottle is more likely to be found in a kitchen cupboard than in a cosmetics bag, so if you travel often, a smaller package of the same formula will be more convenient, while you can leave the large one at home as a backup. It's also worth remembering the expiration date: with a large package, it's wise to check it at purchase and compare it with how quickly you actually consume the product. The product is intended for adults. Pregnant and breastfeeding women, those taking anticoagulant medications, and individuals with kidney diseases should consult a doctor before starting supplementation, as vitamin K2 interacts with vitamin K antagonists. If you do not have a current 25(OH)D blood test result, start with that - the manufacturer recommends this exact order of actions, and it's worth discussing the result with a doctor or pharmacist.

Frequently asked questions

How many capsules are in the package and how big is the bottle?

The package contains 240 capsules, and the bottle has a capacity of 250 ml. Both values are provided by the manufacturer on the product card. With such a large supply, it's important to pay attention to the expiration date on the package and compare it with how quickly you actually consume the product - this is a reliable method to assess whether this format is worthwhile for you.

Does the composition differ from smaller packages?

No. The manufacturer provides the same content in the capsule for all package sizes: 250 µg of cholecalciferol and 200 µg of menaquinone-7, with the same rice fillers and the same coating made of hydroxypropyl methylcellulose. The only difference is the number of capsules and the capacity of the bottle in which they are packaged.

Is the preparation vegan?

The capsule coating is plant-based, made of hydroxypropyl methylcellulose, but cholecalciferol is derived from lanolin, which comes from sheep's wool. This is an animal-derived raw material. If this is a condition for your purchase, check the declaration on the package or write to us - we will verify the label of the batch we have in the store.

How to store such a large package?

The manufacturer briefly states: store in a cool, dry place, out of reach of small children. In the original and tightly closed bottle, of course. We would add that a kitchen cupboard away from the stove works better than a windowsill in full sun or a shelf in the bathroom, where humidity can be high. Close the bottle immediately after measuring out a portion.

Variants and category

Navigator sells the same formula in several package sizes - in our store, it is also available in a medium package and a trial package. The cholecalciferol alone, without vitamin K2, is offered by the manufacturer in soft gel capsules. We have gathered the full range of supplements in the category Supplements.

Safety and storage

The product is a dietary supplement intended for adults and is not a medical product. The manufacturer recommends performing a 25(OH)D blood test before starting supplementation and consulting the result with a doctor or pharmacist - with such a concentrated dose of vitamin D3, this is a sensible order of actions. Do not use in case of hypersensitivity to any of the ingredients. Pregnant and breastfeeding women and individuals taking medications regularly, including anticoagulants, should consult the use of the product with a doctor. Store in a cool, dry place, out of reach of small children. Keep the package out of reach of small children and do not use after the expiration date.

Do not exceed the recommended daily serving. Dietary supplements do not replace a varied diet or a healthy lifestyle.
