People who take Coumadin (also known as warfarin) often worry about what foods are safe to eat. This medication helps prevent blood clots, but it can interact with vitamin K, which affects how well Coumadin works. Knowing the vegetables you can eat while taking Coumadin can help you keep your diet healthy and your blood levels steady.
Understanding Coumadin and Vitamin K
Coumadin works by slowing the body’s ability to form clots. Vitamin K plays an important role in this same process. When a person eats too much or too little vitamin K, it can make Coumadin less effective or too strong.
According to the American Heart Association, keeping your vitamin K intake consistent is the key. This doesn’t mean you must avoid vegetables, but you should know which ones are safer to eat in regular amounts.
Safe Vegetables for People on Coumadin
According to research published in the Journal, here are several vegetables that are generally safe when eaten in consistent portions. These foods contain lower or moderate levels of vitamin K and offer many health benefits.

Vegetables to Eat in Moderation

- Broccoli
- Spinach
- Kale
- Brussels sprouts
- Collard greens
If you like these foods, talk with your healthcare provider or dietitian about how much you can safely include. The National Institutes of Health (NIH) notes that eating the same amount of these vegetables daily keeps your Coumadin dose stable.
