Why customers take it

Vegan & natural

Vitamin K supplements are often extracted from bacteria or made synthetically in a lab. Ours is natural, and comes from a fermented vegetable called natto. This makes our 100% Vegan Vitamin K a very popular choice. 

Strong bones

Vitamin K is involved in bone metabolism and helps regulate calcium within bones and blood vessels. Adequate vitamin K levels contribute to bone health and may be important for preventing conditions like osteoporosis.


Women going through menopause sometimes boost their Vitamin K for bone health, as hormonal changes during this stage can affect bone density.

Heart health

It's thought that Vitamin K may play a role in preventing hardening of the arteries, and some people take it as part of a nutritional approach to supporting heart health. 

Better skin

Some people take Vitamin K supplements to support skin elasticity and reduce the appearance of certain skin conditions, such as dark circles under the eyes.
