If you love foods like broccoli, cauliflower, or Brussels sprouts, you might already be getting a good dose of vitamin K. Though often overshadowed by vitamins like D, C, and E, vitamin K is just as essential for your health. According to the National Library of Medicine, about 13% of adults suffer from vitamin K deficiency, highlighting how crucial it is to make sure we’re getting enough. From supporting blood clotting to strengthening bones and even promoting heart health, vitamin K does a lot more than you might think. It also plays a significant role in helping your body absorb vitamin D—a nutrient that’s especially important in winter when sunlight is scarce.
But is eating vitamin K-rich foods enough, or should you consider supplementation? Let’s explore the vital role of vitamin K in your health and why combining it with vitamin D is a powerful duo.
What Is Vitamin K Used For?
Vitamin K refers to a group of fat-soluble vitamins, primarily classified into two forms:
- Vitamin K1 (phylloquinone): Found mainly in green leafy vegetables
- Vitamin K2 (menaquinone): Present in animal products, fermented foods, and produced by gut bacteria
Here are some key roles that vitamin K plays in your health:
- Blood Clotting
Vitamin K is essential for proper blood clotting. It helps prevent excessive bleeding from injuries or surgeries by enabling the formation of clotting factors. Without vitamin K, your body would struggle to heal wounds effectively.
- Bone Health
Vitamin K is crucial for bone health because it helps bind calcium to your bones, making them stronger. This process reduces the risk of conditions like osteoporosis and helps prevent fractures, particularly after menopause when bone density often decreases.
- Cognitive Function
Emerging research suggests that vitamin K could have a protective role in brain health. Some studies have even linked adequate vitamin K intake with a reduced risk of Alzheimer’s disease and improvements in cognitive function.
- Enhanced Efficacy with Vitamin D
When vitamin K is taken alongside vitamin D, they work synergistically to maximize the benefits of both. Vitamin D helps synthesize proteins that regulate calcium in the body, but these proteins require activation by vitamin K. Without enough vitamin K, these proteins remain inactive, leading to improper calcium distribution. This can cause calcium to build up in arteries, contributing to heart disease, rather than being directed to bones where it’s needed most.
- Prevention of Calcium Buildup
Vitamin K2 plays an essential role in preventing excess calcium from accumulating in the arteries and soft tissues. By activating specific proteins, vitamin K ensures that calcium is directed toward bones, reducing the risk of cardiovascular problems.
Where Can You Find Vitamin K?
A balanced diet rich in vitamin K can easily meet your daily needs. Additionally, vitamin K is produced by your gut flora, and any excess is stored in the liver, releasing it when required. Foods rich in vitamin K include:
- Green leafy vegetables: Spinach, kale, chard, turnip greens
- Cruciferous vegetables: Broccoli, cauliflower, Brussels sprouts
- Vegetable oils: Olive oil, soybean oil
- Fermented foods: Sauerkraut, kimchi, kefir
- Animal products: Eggs, butter, chicken breast, liver
- Fermented soybeans (Natto): An outstanding source of vitamin K
- Dairy: Blue cheeses, such as Gorgonzola
- Fruits: Blueberries, figs
Why Should Vitamin D Be Taken with Vitamin K?
Vitamin D and vitamin K work best when taken together. Vitamin D is essential for calcium absorption, but it requires Vitamin K health impacts to activate the proteins that help regulate calcium in your body. Without vitamin K, the calcium you absorb from food or supplements might not be properly utilized, potentially leading to calcium buildup in arteries or soft tissues—putting your heart and overall health at risk. When taken together, these vitamins support each other in ensuring calcium is directed to your bones, promoting both bone and cardiovascular health.
How Much Vitamin K Do You Need?
The recommended daily intake of vitamin K is:
- 90 mcg for women
- 120 mcg for men
To optimize absorption, it’s best to take vitamin K with a meal containing fat, as it is a fat-soluble vitamin.
Who Should Consider a Vitamin K Supplement?
There are certain groups of people who may benefit from vitamin K supplementation:
- Those with malabsorption conditions: Individuals with celiac disease or inflammatory bowel disease may have difficulty absorbing vitamin K.
- Those on long-term antibiotics: Prolonged antibiotic use can disrupt the gut bacteria that produce vitamin K.
- Those with blood clotting issues: People with low levels of prothrombin (a protein involved in blood clotting) may need additional vitamin K to help prevent bleeding.
