Alfalfa for vit k and bleeding after birth

I met with a nutritionalist at my birth center and she told me if I take alfalfa supplements it really helps your vitamin k levels and helps keep bleeding to a minimum after birth. I've read SO many books and done SO much research and never heard this. I had to share bc it seems like it should be common knowledge for expecting mamas! Both to prevent hemoraging right after birth and lessen bleeding in the weeks after. Just wanted to shared I found alfalfa capsules on Amazon for $8
