Vitamin K
affects clotting of the blood, but it also influences the bone strength
and the health of the arteries. A specific form of vitamin K is found in
green vegetables, cheese, liver, yogurt, cauliflower, Brussels sprouts,
tomatoes, spinach, broccoli, beans, lean meat and soy beans.
Low vitamin K
in the blood may be associated with an increased risk of osteoporosis
and extra supplements of vitamin K may be necessary to boost bone
health.
In a few
experiments, vitamin K was found to play a role in Alzheimer's disease,
but it is too early for definite conclusions yet.
Vitamin K is
available in tablet or injection form, but it is not widely used as a
health supplement at present. In the meantime, it may be worth choosing
vitamin K rich food from the list above.
