He doesn t eat but does take a vitamin a day that has 75% of daily requirement of vitamin k (has taken them since October. he is 6 -2 weight 208 steadily. Has diabetes, had a silent heart attack and slight stroke in October. He did eat a lot of my chocolate chip cookies that are made with sliced beets...would that cause it?
