Vitamin K is a group of vitamins that contributes to normal blood clotting (as well as being beneficial for bone health). In the UK, the NHS recommends that adults consume 1 microgram a day of vitamin K for each kilogram of their body weight. There’s increasing evidence vitamin K is important for heart health – recent research suggests that people eating a diet rich in vitamin K have up to a third lower risk of cardiovascular disease due to atherosclerosis (where the arteries thicken and narrow).
In adults, vitamin K deficiency is relatively rare and it should be possible to get enough vitamin K from a healthy, balanced diet. Vitamin K1 is mainly found in green leafy vegetables as well as olive oil and soybean oil, and vitamin K2 is found in small amounts in foods including chicken, butter, egg yolks and cheese.
To ensure they are getting enough, some people also choose to take a vitamin K supplement, such as Nature’s Truth Vitamin K2.
Lifestyle habits that contribute to a healthy heart

A significant UK study published in 2022 found that those eating a diet rich in vegetables, and especially raw veg, had a 15% lower risk of dying from cardiovascular disease. However, eating a healthy, balanced diet that is rich in vegetables won’t protect you from heart disease on its own: the study’s researchers pointed out that other lifestyle factors could also explain the results, including whether people smoked, their alcohol intake, the jobs they did and their general diet.
There is robust evidence that regular exercise is good for heart health, including reducing your risk of coronary heart disease. In the UK, it’s recommended by the Chief Medical Officer that adults should try to be active every day and aim to do at least 150 minutes of moderately intense physical activity over a week.
Over time, being physically active helps lower your blood pressure, improves blood flow and lowers heart rate. It also helps reduce your LDL cholesterol levels, the ‘bad’ cholesterol that can build up in your arteries, potentially causing blockages, and raises your HDL cholesterol, the ‘good’ cholesterol that actually removes fat from arteries.
By making the right lifestyle choices and further supporting your health with supplements proven to help, you can ensure you’re doing your best to protect and support the heart.
