Vitamin K Vitamins & Supplements at Walgreens

Vitamin K is a fat-soluble vitamin and an important nutrient for our health. Vitamin K plays a critical role in blood clotting and building strong bones, and it’s present throughout the body. Vitamin K can be found in many foods but is also available in supplement and multivitamin form. Walgreens offers a variety of products containing vitamin K available for purchase in stores or online.


What is vitamin K?

Vitamin K is a fat-soluble nutrient that comes in two main forms. The major dietary form of vitamin K is called phylloquinone or vitamin K1, which is found in green leafy vegetables. The other type is a group called menaquinones, also known as vitamin K2, which is found in some animal products or fermented foods. Menaquinones can also be produced by some bacteria in our intestines. Vitamin K helps produce key proteins that clot our blood and build bone tissue.


What are the benefits of vitamin K?

Vitamin K helps our bodies function properly, primarily by creating proteins that clot our blood. Our blood needs to be able to clot in order to avoid severe health risks. Vitamin K also produces a protein that protects against bone weakness and promotes bone density.


Can I buy vitamin K over the counter at Walgreens?

Yes, you can buy vitamin K over the counter in multiple forms at Walgreens including daily multivitamins containing vitamin K and standalone vitamin K supplements. Most vitamin K supplements contain vitamin K2, also known as menaquinones, but both types of vitamin K are available in vitamin and supplement form. If you have questions about taking this vitamin, speak with a healthcare provider or pharmacist.


How many milligrams of vitamin K can I take in one day?

Adequate intake of vitamin K is considered to be 120 micrograms (mcg) for adult men and 90 mcg for adult women. However, if you are currently taking blood-thinning medications, consult your healthcare provider before taking vitamin K. It is important to find a healthy balance under a doctor’s supervision to ensure your vitamin K intake does not impact the efficacy of blood-thinning medication.


What are symptoms of vitamin K deficiency?

Vitamin K deficiency is rare, but it may be more common in people taking certain medications. Signs of deficiency may include bleeding or hemorrhaging and bruising easily. Vitamin K deficiency can be checked in a doctor’s office by measuring how quickly blood clots. Your doctor can provide more information about the signs and symptoms of vitamin K deficiency.


Who should take vitamin K?

Most people can get proper amounts of vitamin K from their diets and from production within their bodies. Speak with your healthcare provider if you are worried about your vitamin K intake. Vitamins and supplements can help provide additional vitamin K for those at risk of vitamin K deficiency.


Which foods are high in vitamin K?

Vitamin K in the form of phylloquinone can be found in leafy greens and vegetables such as kale, Brussels sprouts, spinach, and cauliflower. The other form of vitamin K, called menaquinones or vitamin K2, can be found in animal products such as fish, liver, meat and eggs. It can also be found in some fermented foods such as fermented soybeans (natto).


Does vitamin K affect blood pressure?

There is some evidence that low vitamin K levels may be associated with higher blood pressure in some populations. More research is needed to determine the connection between vitamin K and blood pressure. Speak with your healthcare provider if you are worried about your blood pressure or want to learn more.


What is the difference between vitamin K and vitamin K2?

Vitamin K2 is one form of vitamin K, and it’s another term for menaquinones. This is the version of vitamin K found in some animal products and fermented foods.
