This combination of two fat-soluble vitamins in one capsule is declared by the manufacturer to contain 250 \u00b5g of cholecalciferol, which is 10,000 IU of vitamin D3, corresponding to 5000% of the reference intake value, and 200 \u00b5g 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.<\/p>\n
Content per daily serving, which is one capsule, according to the manufacturer's declaration:<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
The manufacturer declares 250 \u00b5g of cholecalciferol, which is 10,000 IU of vitamin D3, corresponding to 5000% of the reference intake value, and 200 \u00b5g 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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
