Navigator Vitamin D3 10000 IU + K2 MK-7 200 µg - 90 capsules, dietary supplement for bones and immunity

Navigator Vitamin D3 10 000 IU + K2 MK-7 200 µg - 90 capsules

Navigator combines two fat-soluble vitamins in one capsule: cholecalciferol and menaquinone-7. The manufacturer declares 250 µg of cholecalciferol, which is 10 000 IU of vitamin D3, and 200 µg of vitamin K2 in the form of MK-7 per serving. Cholecalciferol is derived from lanolin, which is fat from sheep wool, and menaquinone is produced through the fermentation of natto by Bacillus subtilis bacteria.

The rest of the capsule is filled with rice materials (concentrate, extract, and gluten-free rice flour), and the coating is made of hydroxypropyl methylcellulose, which is a plant material. The packaging contains 90 capsules in a 120 ml bottle, and the manufacturer recommends storing it in a cool, dry place, out of reach of children. The ingredient list is short and intended to be so: besides the two vitamins and rice fillers, the manufacturer declares the formula to be free from sugar, lactose, gluten, starch, wheat, corn, and magnesium stearate.

The capsule is hard and should be swallowed whole with water.

Ingredients

Content declared by the manufacturer in one capsule:

• Vitamin D3 (cholecalciferol from lanolin) - 250 µg, which is 10 000 IU (5000% RDA)
• Vitamin K2 MK-7 (menaquinone-7 from natto fermentation by Bacillus subtilis bacteria) - 200 µg (267% RDA)
• Fillers: rice concentrate, rice extract, gluten-free rice flour
• Capsule coating: hydroxypropyl methylcellulose

Cholecalciferol comes from lanolin - a waxy secretion from sheep glands, recovered during shearing. It is an animal-derived material, although it does not require slaughter. Menaquinone-7, on the other hand, is a product of fermentation: Bacillus subtilis bacteria process soybeans into natto, from which vitamin K2 in the form of MK-7 is obtained, which is menaquinone with seven isoprene units in the side chain. The origin of both vitamins is the most common question regarding this type of formula.

Fillers are as important here as the active ingredients: instead of typical anti-caking agents, the manufacturer used three rice materials and explicitly declares the absence of magnesium stearate. The coating made of hydroxypropyl methylcellulose is a standard substitute for gelatin, found in hard capsules. The entire list consists of six items and nothing more. The percentages given for both vitamins are reference intake values for adults, meaning a reference to daily requirements, not to the size of the product serving.

Specification

Usage

The manufacturer states that a serving consists of one capsule taken with a meal.

• Serving: 1 capsule
• Take with a meal
• Swallow with water, do not chew the capsules
• Frequency - according to the label on your packaging
• Do not exceed the recommended daily serving

For whom

This is a proposal for adults who want to have vitamin D3 and vitamin K2 MK-7 in one preparation instead of two separate packages, and who prefer a concentrated dose instead of a small daily dose. The hard capsule format with a plant coating may be an argument for those avoiding gelatin in the coating, although cholecalciferol is derived from lanolin, so the product is not free from animal-derived materials.

The packaging contains 90 capsules, and the 120 ml bottle does not take up much space in the cupboard and fits comfortably in a travel cosmetic bag. The product is intended for adults. Pregnant and breastfeeding women, individuals taking anticoagulant medications, and those 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 is 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?

There are 90 capsules in the package, and the bottle has a capacity of 120 ml. The manufacturer provides both values on the product card. The bottle is clearly larger than the volume of the capsules themselves, which is typical for this format - the extra space facilitates pouring out servings and protects the contents from clumping during transport.

Is this product vegan?

The capsule coating is made of hydroxypropyl methylcellulose, which is a plant material, but cholecalciferol is derived from lanolin, and thus from sheep wool. It is an animal-derived material.

Why does the manufacturer combine vitamin D3 with vitamin K2?

Both vitamins are fat-soluble, which is why they are often combined in one formula, and that is why the manufacturer recommends taking the capsule with a meal. The practical consequence is that instead of two separate packages, you have one hard capsule with a plant coating, with each vitamin coming from a different source: cholecalciferol from lanolin and menaquinone from natto fermentation.

How to store the capsules?

The manufacturer states briefly: in a cool, dry place, out of reach of small children. Keep the capsules in the original, tightly closed bottle and choose a kitchen cupboard instead of a bathroom shelf, where humidity can be high. Close the bottle immediately after measuring out a serving and do not transfer the capsules to a weekly organizer.

Variants and category

The same formula is sold by Navigator in several package sizes - we also have it in a smaller package and in a backup version for longer use. The product with just cholecalciferol is packaged in soft gel capsules. We have gathered the full offer of supplements in the Supplements category.

Safety and storage

The product is a dietary supplement intended for adults and is not a medical product. The manufacturer recommends that before starting supplementation, a 25(OH)D blood test be performed and the result discussed 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 packaging 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.
