Seniors consume more Vitamin K than do younger people but according to researchers at Tufts University, they still don’t get enough.

Low Vitamin K intake may be associated with conditions such as bone fractures, bone loss, hardening of the arteries, and osteoarthritis - all conditions of major concern in older patients. It is also thought that high levels of phylloquinone (the plant form of Vitamin K) is an indicator of lower risk of coronary heart disease.

Vitamin K is found in leafy vegetables (especially spinach and celery), cheese and liver. It is also found in asparagus, coffee, bacon and green tea. Toxicity rarely occurs with normal dietary intake of Vitamin K but can
happen if the synthetic form, K3 is taken as a supplement.

If you take an anticoagulant, consult your doctor before taking a Vitamin K supplement.
