The recommended nutrient intake (RNI) would therefore be: 900 x (2.9 + 1.2)/100 x 100/85 = 43.4 mg/day, which can be rounded off to 45 mg/day. No turnover studies have been done in women, but from the smaller body size and whole body content of women, requirements might be expected to be lower.
What is the daily recommended amount of vitamin K?
Adults need approximately 1 microgram a day of vitamin K for each kilogram of their body weight. For example, someone who weighs 65kg would need 65 micrograms a day of vitamin K, while a person who weighs 75kg would need 75 micrograms a day.
What is RNI?
The rate of natural increase (RNI) is a measure of how quickly a population is growing or declining. To calculate the RNI, demographers subtract the death rate (number of deaths per 1,000 people/year) from the birth rate (number of birth per 1,000 people/year) and convert the answer to a percentage.
Why is there no RNI for energy?
The RDA for energy, however, reflects the mean population requirement for each group, since consumption of energy at a level intended to cover the variation in energy needs among individuals could lead to obesity in most persons.
What is the RNI for vitamins?
Reference Nutrient Intake These Reference Nutrient Intakes (RNIs) represent the best estimate of the amount of a nutrient that is enough, or more than enough, for about 97 per cent of people in a group.

What does vitamin K do to your body?
Vitamin K is a cofactor for the gamma-carboxylation of many proteins, including osteocalcin, one of the main proteins in bone [30]. Some research indicates that high serum levels of undercarboxylated osteocalcin are associated with lower bone mineral density [5,30].
