Swanson Vitamins Vitamin K2 100 mcg (30 softgels) contains vitamin K2 in the form of menaquinone-7 (MK-7), derived from natto, a fermented soy product. Each softgel provides 100 mcg vitamin K2 combined with sunflower oil. This form is often used in supplements due to its specific composition. The softgels are easy to take and suitable for daily use. With 1 softgel per day, this product is practical to add to a fixed routine.
Vitamin K1 (phylloquinone) is mainly found in green leafy vegetables such as spinach, kale, and broccoli. Vitamin K2 (menaquinone) is primarily found in fermented foods like natto and in smaller amounts in animal products such as cheese and eggs.
Natto is a traditional Japanese food made from fermented soybeans and is one of the richest natural sources of vitamin K2.
MK-4 and MK-7 are both forms of vitamin K2. They differ in chemical structure and come from different sources: MK-4 is mainly found in animal products, while MK-7 is usually derived from fermented foods like natto.
Vitamin K2 is a fat-soluble vitamin and is therefore often combined with oil. This allows the substance to be well incorporated in a softgel and remain mixed.
