Nutrition, Dietetic Products, Novel Food and Allergy
The Norwegian Scientific Committee for Food Safety is requested to evaluate the consequenses of amending the maximum limit for vitamin K in food supplements to 100, 200, 300, 600 or 800 μg per day.
The assignment includes all age groups above 1 year.
The Norwegian Food Safety Authority is considering to establish a new national regulation of food supplements, including maximum limit for vitamin K. The previous maximum limit for vitamin K was 200 µg per day. It was repealed on May 30, 2017.
VKM will also assess the intake of vitamin K from the diet. As there are no intake data for vitamin K from the diet in Norway, VKM is requested to evaluate whether intake data from other countries may be representative for Norwegian conditions.
Vitamin K is fat soluble, and is present mainly in two forms: phylloquinone – vitamin K1 – and menaquinone – vitamin K2. Due to insufficient data, no recommendations for daily intake have been established for vitamin K in Norway.
Leafy green vegetables and vegetable oils are good sources of phylloquinone. Menaquinones are found in liver, meat, egg yolk, and dairy products.
VKM's Panel on Nutrition, Dietetic Products, Novel Food and Allergy will be responsible for this assessment.
