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

This combination of two fat-soluble vitamins in one capsule is declared by the manufacturer to contain 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, or menaquinone-7, which corresponds to 267% of the RI. Vitamin D3 comes from lanolin derived from sheep wool, and K2 is sourced from fermentation conducted by Bacillus subtilis NATTO bacteria. The method of use is more important here than usual and differs from the typical regimen: Navigator recommends taking 1 capsule every 5 days, together with a meal, rather than daily. The package contains 120 capsules. The coating consists of hydroxypropyl methylcellulose, and the fillers 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 gluten-free, lactose-free, and artificial preservative-free formula. The capsule should be swallowed whole and taken with water.

Ingredients

Content per daily serving, which is one capsule, according to the manufacturer's declaration:

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

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

How to use

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

Serving: 1 capsule every 5 days
Take with a meal - both vitamins are fat-soluble
Drink 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

Who is it for

This is a suggestion for adults who want to take both vitamins at once and prefer a less frequent regimen 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 approved for these nutrients. The capsule format does not require refrigeration and is convenient for travel, and the every five days regimen 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 dietary 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 their doctor before starting.

Frequently asked questions

How often should this capsule be taken?

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

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% of the RI. Both values refer to one capsule, not to a daily serving understood as a day.

Is the preparation vegan?

No. Vitamin D3 is cholecalciferol sourced from lanolin, which is fat derived from sheep wool, so the raw material is of animal origin. The capsule coating, however, is plant-based, made from hydroxypropyl methylcellulose, and the fillers are three rice fractions: rice concentrate, rice extract, and gluten-free rice flour. The manufacturer declares the absence of gluten, lactose, and 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 to use it. 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 you need only vitamin K - a product with just menaquinone. You can find the full offer in the category Supplements.
