Source Naturals Vitamin K2 supports bone health. Vitamin K2 is a more biologically active form of vitamin K extracted from a fermented Japanese soyfood called natto, a powerhouse of nutrients. Fat-soluble, it is an essential cofactor for the production of proteins that bind calcium, supporting cardiovascular and bone health. Vitamin K2 is more efficient than K1 because it remains in circulation longer and is active in more tissues.

Contains no yeast, dairy, egg, gluten, soy, or wheat. Contains no preservatives, or artificial color, flavor or fragrance.

Get double the power with this double-strength version of Swanson K2, delivering 100 mcg of vitamin K2. Swanson K2 (formerly Natto K7) is the most biologically active form of vitamin K2. While vitamin K is mostly known for its involvement in blood clotting, K2 also helps to activate the osteocalcin and matrix GLA proteins that regulate where calcium ends up in the body.

Vitamin K2 itself consists of 13 numbered natural substances called menaquinones of which primarily menaquinone-7 has been scientifically studied to benefit cardiovascular and bone health. Studies suggest menaquinone-7 specifically may also support both mood and blood sugar health in women.

Extensive research completed in the Netherlands indicates the natto-derived form of menaquinone-7 helps get calcium out of the arteries and into the bones where it belongs. This promotes bone formation and strength as well as vascular health.

Swanson Vitamin K2 is derived from natto, a fermented soy product that is the richest natural source of K2, and delivers menaquinone-7 in sunflower seed oil-based softgels for better absorbability.

Swanson Natural Vitamin K2 (Menaquinone-7 from Natto) is the most biologically active form of vitamin K2. Everyone knows about calcium and vitamin D for bone health, but what about vitamin K2? If there’s one vitamin you should know more about, this one’s it.

While vitamin K is mostly known for its involvement in blood clotting, K2 also helps to activate the proteins that regulate where calcium ends up in the body, promoting healthy levels in both bones and arteries. Meaning this little-known vitamin is a powerhouse when it comes to healthy bones, and a healthy heart. Our vitamin K2 is derived from 100% natural Japanese natto (a fermented soybean product), and because the Western diet is typically low in fermented foods, it also tends to be low in K2.  Since vitamin K2 is fat soluble, we deliver ours in sunflower oil-based softgels for optimum bioavailability.

Introducing the perfect cardio-supporting pair: Vitamin K2 with Nattokinase. Numerous studies have suggested that menaquinone-7 (vitamin K2) supports cardiovascular wellness by producing proteins that promote healthy calcium absorption. Once called "stringy soybeans," the traditional Japanese food natto is a source of vitamin K2 that also features a unique enzyme called nattokinase, which breaks down fibrin to support healthy circulation. These softgels deliver both natto-derived nutrients for convenient supplementation.
