For the first time in my 69 years, I have gotten a sudden, painless nosebleed three times in the past three days. I have learned to love greens and eggs for breakfast and have that most every morning. This week we had all four of my faves: kale, spinach, bok choy, and romaine. I suppose I ODd on Vit K, perhaps? If so, how long should I lay off of it to fix this? Is there a safe amount each day?
