| Vitamin K2 (menaquinone) | 80µg | 83% |
K1 and K2 are not the same thing
Vitamin K comes in two main forms. K1, phylloquinone, is the one in leafy greens: kale, spinach, broccoli. K2, menaquinone, is found in fermented foods and some animal products, and is far less common in a typical UK diet.
Most multivitamins that list vitamin K are using K1, because it is cheaper. We use K2, which is why it appears on the label as menaquinone rather than simply vitamin K.
MK-4 and MK-7
K2 itself has subtypes, named by the length of their side chain. MK-4 and MK-7 are the two you will see on labels. MK-7 is typically produced by fermentation, classically from natto, the Japanese fermented soybean dish, and it stays in circulation longer than MK-4.
It travels with vitamin D
K2 and vitamin D3 are usually formulated together, which is why they sit in the same gummy here. Both are fat soluble, so both are absorbed better with a meal, and taking the whole pouch with food covers that.

An important caution
Vitamin K interacts with warfarin and other anticoagulant medication. If you take a blood thinner, speak to your GP or anticoagulation clinic before taking any supplement containing vitamin K, in either form. This is not a minor caveat and it applies at any dose.
Where else you find it
Natto is by far the richest dietary source, though it is an acquired taste and rare outside Japan. Smaller amounts appear in hard cheeses, egg yolks and some fermented foods. Unlike K1, it is not something you pick up easily from vegetables.
Which gummy carries it
Vitamin K2 sits in Daily Greens+, tropical flavour, alongside vitamin D3, vitamins A, C and E, the B complex, zinc, copper, iodine and chromium and the superfood greens blend.

Speak to your GP or anticoagulation clinic first. Vitamin K interacts with warfarin and other anticoagulants, and this applies to any supplement containing it.
