Vitamin D3 4000 IE + K2 110 tabletter

In periods with little sun — and with a life that mostly takes place indoors — your skin hardly produces any vitamin D. Precisely then you notice how nice a fixed routine is: one small tablet with breakfast, and your daily supplement is sorted. No measuring out oil, no counting drops — just a tablet that you swallow effortlessly.

The formula combines two fat-soluble vitamins that are naturally often mentioned together. Cholecalciferol is the same form of vitamin D that your skin makes itself under summer sun and that you find in small amounts in fatty fish. Vitamin K2 comes from fermentation with Bacillus subtilis natto — the same bacterial culture that has been used in Japan for centuries for the traditional dish natto — and is supplied in the menaquinone-7 form, the variant that the body absorbs well and that remains available in the blood for a long time.

This is a tablet for a broad audience: the student who studies indoors all winter, the home worker who barely sees daylight, the athlete who wants to have their basics in order and the active over-60 who is building their routine. The manufacturer explicitly states that the product is also suitable for people over 75 and advises taking a 25(OH)D blood test beforehand and consulting a doctor or pharmacist — sensible at this higher dose.

In the low-sun months this one tablet does what the sun leaves undone — and with 110 pieces your routine is covered for a good three and a half months. The product contains none of the legally designated allergens as an ingredient; the manufacturer does not issue a vegan or vegetarian statement.

Vitamin D3 (cholecalciferol): 100 µg (4000 IU) per tablet — 2000% of the reference intake.

Vitamin D is found naturally mainly in oily fish. To get 100 µg from food you would have to eat about 600 g of wild salmon or more than 1.2 kg of herring every day — every single day, while your skin makes virtually none in the months with little sun. The body stores vitamin D in fatty tissue and the liver.

Vitamin K2 (menaquinone-7 from Bacillus subtilis natto): 100 µg per tablet — 133% of the reference intake.

MK-7 is the K2 variant from fermented foods; the best-known natural source is natto, and for 100 µg you would have to eat around 10 g of natto a day — a dish that is hardly available outside Japan. D3 and K2 are often taken together because both are fat-soluble and suit the same meal.
