Can I get enough Vitamin K1 from my diet alone?
It is possible to meet your Vitamin K1 needs through diet, especially if you consume plenty of leafy green vegetables like spinach, kale, and broccoli. However, supplements can ensure consistent intake.
Are there any side effects of Vitamin K1 supplements?
