Navigator Vitamin D3 10000 IU + K2 (MK-7) 200 µg | 120 capsules - high doses of vitamins D and K for bone and cardiovascular support

Navigator Vitamin D3 10000 IU + K2 MK-7 200 µg - 120 capsules

This combination of two fat-soluble vitamins in one capsule. The manufacturer declares a daily portion of 250 µg of cholecalciferol, which is 10 000 IU of vitamin D3, corresponding to 5000% of the reference intake value, and 200 µg of vitamin K2 in the form of MK-7, which is menaquinone-7, corresponding to 267% RI. Vitamin D3 comes from lanolin from sheep wool, and K2 from fermentation conducted by Bacillus subtilis NATTO bacteria. The method of use is more important here than usual and differs from the typical scheme: Navigator recommends 1 capsule every 5 days, taken with a meal, rather than daily. The package contains 120 capsules. The coating consists of hydroxypropyl methylcellulose, and the filling substances are rice concentrate, rice extract, and gluten-free rice flour. The product is manufactured by the British company Navigator Supplements from London, and the manufacturer declares a recipe free from gluten, lactose, and artificial preservatives. The capsule is swallowed whole and washed down with water.

Ingredients

Content in the daily portion, that is, in one capsule, according to the manufacturer’s declaration:

• Vitamin D3 (cholecalciferol from lanolin from sheep wool) - 250 µg, which is 10 000 IU, corresponding to 5000% RI
• Vitamin K2 MK-7 (menaquinone-7 from Bacillus subtilis NATTO fermentation) - 200 µg, corresponding to 267% RI
• Filling substances: rice concentrate, rice extract, gluten-free rice flour
• Capsule coating: hydroxypropyl methylcellulose

This recipe is short, and each of its elements has a specific justification. Cholecalciferol obtained from lanolin is the most commonly found form of vitamin D3 in supplements - lanolin is a fat from sheep wool, so the raw material is animal-derived, although its extraction does not require slaughter. Menaquinone-7 from fermentation by Bacillus subtilis NATTO bacteria is the same form of vitamin K2 that you will find in Japanese natto. The percentage values (5000% RI for D3 and 267% RI for K2) refer to the reference intake values for an adult and show why the manufacturer does not recommend daily intake of the capsule. The carriers are three rice fractions instead of oil, so the capsule is dry, not soft and oily like in preparations solely with vitamin D, and the coating is plant-based, made of hydroxypropyl methylcellulose. The manufacturer declares the recipe as free from gluten, lactose, and artificial preservatives.

Method of use

The manufacturer recommends 1 capsule every 5 days, taken with a meal. This recommendation deviates from the daily scheme known from preparations with lower doses and directly results from the content of vitamin D3 in the capsule, so it is worth adhering to it.

• Portion: 1 capsule every 5 days
• Take with a meal - both vitamins dissolve in fats
• Wash down with water, swallow the capsule whole
• Do not exceed the recommended portion
• With high doses of vitamin D, it is advisable to discuss supplementation with a doctor

For whom

This is a proposal for adults who want to take both vitamins at once and prefer a less frequent scheme than a daily capsule. Vitamin D helps in the proper functioning of the immune system and in maintaining healthy bones, while vitamin K contributes to proper blood clotting and also to maintaining healthy bones - these are statements permitted for these nutrients. The capsule format does not require refrigeration and is convenient for travel, and the every five days scheme means that one package lasts a long time without daily monitoring. However, there are two limitations. First, vitamin D3 comes from lanolin, which is an animal-derived raw material, so the product does not meet vegan diet criteria. Second, vitamin K interacts with anticoagulant medications, so individuals taking them should consult their doctor before using the product. The product is intended for adults, and pregnant and breastfeeding women should discuss supplementation with a doctor before starting it.

Frequently asked questions

How often should I take this capsule?

The manufacturer recommends 1 capsule every 5 days, with a meal. This is not a product for daily use, and the scheme directly results from the content of vitamin D3 in the capsule. Adhering to the manufacturer’s recommendation is more important here than with preparations with lower vitamin D content.

How much vitamin D3 and K2 is in one capsule?

The manufacturer declares 250 µg of cholecalciferol, which is 10 000 IU of vitamin D3, corresponding to 5000% of the reference intake value, and 200 µg of vitamin K2 in the form of MK-7, which is 267% RI. Both values refer to one capsule, not a daily portion understood as a day.

Is the product vegan?

No. Vitamin D3 is cholecalciferol obtained from lanolin, which is fat from sheep wool, so the raw material is of animal origin. The capsule coating is plant-based, made of hydroxypropyl methylcellulose, and the fillers are three rice fractions: rice concentrate, rice extract, and gluten-free rice flour. The manufacturer declares no gluten, lactose, or artificial preservatives.

Can this product be combined with medications?

Vitamin K affects blood clotting and interacts with anticoagulant medications, so individuals taking such medications should consult their doctor before starting use. The same applies to individuals taking other medications regularly and to pregnant and breastfeeding women.

Variants and category

If you need only vitamin D, the same line has a version with just vitamin D3, and if only vitamin K - a preparation with just menaquinone. You can find the full offer in the Supplements category.
