Everything You Need to Know about Vitamin K

January 08, 2025 5 min read

I remember when I first started taking my diet seriously.

I focused on the big things—protein, carbs, fats—and made sure I hit my targets daily. But I still felt something was off.

Growing up, everyone tells you “eat a balanced diet”, but did any of us really listen? I sure didn’t! 

I never understood the importance of balancing your micronutrients. Not until I focused on them did I realize the massive difference.

My energy levels were inconsistent, my recovery after workouts was slow, and I kept getting bruises from the lightest bumps.

It took me years to realize that I was neglecting important nutrients, vitamin K included. This oversight had a significant impact on my overall health and well-being.

That being said, here is all you need to know about Vitamin K, and what foods to eat to get all you need.


The Importance of Vitamin K

 

Vitamin K is a crucial nutrient that plays a vital role in several bodily functions. There are two main types of vitamin K: K1 (phylloquinone) and K2 (menaquinone).

Vitamin K1 is found mostly in green leafy vegetables like spinach, kale, and broccoli. It helps your blood clot properly.

Vitamin K2 is found in animal products and fermented foods. It is important for bone and heart health.


Functions of Vitamin K


Blood Clotting: It is necessary for making proteins required for blood coagulation. And without enough vitamin K, even a small cut could lead to excessive bleeding.


Bone Health: Vitamin K2 helps manage calcium, keeping it in your bones and out of your arteries. So this reduces the risk of weak bones and heart diseases.


Heart Health: Because vitamin K2 prevents calcium deposits in the arteries, it helps keep your arteries flexible and lowers the risk of heart disease.


Where to Get Vitamin K


Here are some common foods that are good sources, and how much you get per serving:

Kale: 1 cup (raw) - 547 micrograms of vitamin K1
Spinach: 1 cup (raw) - 145 micrograms of vitamin K1
Broccoli: 1 cup (cooked) - 220 micrograms of vitamin K1
Brussels Sprouts: 1 cup (cooked) - 156 micrograms of vitamin K1
Kiwi: 1 medium-sized - 27.8 micrograms of vitamin K1
Natto (fermented soybeans): 1 ounce - 150 micrograms of vitamin K2
Cheese (hard cheeses like Gouda): 1 ounce - 10 micrograms of vitamin K2
Egg Yolk: 1 large - 0.3 micrograms of vitamin K2
Chicken Liver: 1 ounce - 3 micrograms of vitamin K2


Daily Requirements


The recommended daily intake of vitamin K is:


Men: 120 micrograms
Women: 90 micrograms


Signs of Vitamin K Deficiency


Vitamin K deficiency is rare but can lead to serious health issues. Symptoms include:

  • Easy bruising
  • Excessive bleeding
  • Heavy menstrual periods
  • Blood in urine or stool
  • Weak bones


How to Ensure Adequate Intake


Eat a Balanced Diet: Include both vitamin K1 and K2 rich foods in your diet. A mix of leafy greens, fruits like kiwi, and fermented foods can cover your needs.


Supplements: If you have trouble getting enough vitamin K from your diet, consider taking a supplement after consulting with your healthcare provider.


Monitor Medication: Some medications, like blood thinners, can interfere with vitamin K. But always discuss with your doctor before making any changes.


Conclusion


Understanding the importance of nutrients like vitamin K transformed my approach to nutrition. So by ensuring you get enough of these essential nutrients, you can significantly improve your overall health. Learn more about nutrition and wellness here.

Don't make the same mistakes I did—pay attention to these important nutrients so you can enjoy the benefits of a well-rounded diet.

P.S. Pro tip: 2 kiwis a day is 50% of your RDI, that’s my personal choice to get most of my Vitamin K every day

FAQ

Porrada is a Portuguese term commonly used in Brazilian Jiu-Jitsu (BJJ) and Brazilian culture to describe a tough, intense, and gritty style of training or fighting. The direct translation of porrada from Portuguese to English is "beating" or "brawl." It embodies the spirit of going all out, giving your maximum effort, and pushing through challenges. In BJJ, practicing porrada means training with high intensity and determination.

This website is a collection of resources curated by grapplers, for grapplers. Our goal is to provide you with all the information you need to succeed. Whether you want to learn about nutrition, training on the mats, lifting, or anything in between, we are here for you. We want to see you on the podium most of all, and we hope to help you do exactly that. If you have any questions, feel free to shoot us an email or DM us on any of our social profiles!

There are two main ways you can get started with training: 1) You can find a BJJ gym near you and do a trial day, or 2) you can create your own mini home gym and start training with friends. Option #2 is how our team at Porrada got started! We ordered 1-inch thick puzzle mats in a 10’x10’ square and began training using online resources. If you do start with the second option, we recommend eventually finding a gym down the road in your career. It will help you by allowing you to roll with more people and receive high-level instruction.

BJJ is quite similar to wrestling. Both start standing and use takedowns as a method to score points. Both use very similar mechanics overall. The main differences are that there are no pins (you can be on your back in Jiu-Jitsu), BJJ involves submissions, and the points system for each is very different. BJJ grants points for takedowns/sweeps, back control, mount, guard passes, and knee on belly. Wrestling grants points for takedowns, escapes, and back points (back exposure for freestyle).

BJJ is a very unique sport in many ways. There are so many incredible benefits to training Jiu-Jitsu. The biggest reasons we advocate for it are the mindset training and the added ability to defend yourself. In BJJ, you are forced to humble yourself over and over again, every single day. This sport is a great way to mature rapidly and generally become a better person (in our opinion). You will also have a better ability to defend yourself than 99% of the population—a pretty big bonus.

You’re never too old to start training! We see people on the mats of all ages and sizes. Large and small, old and young can, and should, train BJJ. If you are on the older side, it is perfectly acceptable to take it slow and learn at your own pace. You don’t always have to go full speed—don’t worry. There are typically also classes that separate people by goals. Certain classes are for those who want to compete, some are for general instruction, and some are specifically for self-defense teachings. There is a place for everyone on the mats.
