12 best vitamin k supplements

Vitamin K supplements provide a synthetic form of vitamin K, a fat-soluble vitamin that plays a vital role in blood clotting and bone health. Here's some information about vitamin K supplements:

  1. Types of Vitamin K: There are two primary forms of vitamin K: vitamin K1 (phylloquinone) and vitamin K2 (menaquinone).

    • Vitamin K1: Found in leafy green vegetables, K1 is primarily involved in blood clotting.
    • Vitamin K2: Found in fermented foods and animal products, K2 is involved in both blood clotting and bone metabolism.
  2. Functions: Vitamin K is essential for the synthesis of clotting factors in the blood. Without adequate vitamin K, the blood may not clot properly, which can lead to excessive bleeding. Additionally, vitamin K plays a role in bone health by assisting in the regulation of calcium deposition in bones and teeth.

  3. Dietary Sources: In addition to supplements, vitamin K is naturally present in various foods. As mentioned earlier, vitamin K1 is found in leafy greens (e.g., spinach, kale), while vitamin K2 is found in foods like cheese, natto (fermented soybeans), and animal liver.

  4. Supplementation: Vitamin K supplements are available in various forms, including capsules, tablets, and liquid drops. They are typically used to address vitamin K deficiencies or as part of a treatment plan for certain medical conditions.

  5. Medical Uses: Vitamin K supplements may be prescribed or recommended by healthcare professionals for individuals with specific conditions, such as bleeding disorders or certain types of liver disease. They may also be given to newborns to prevent a rare bleeding disorder known as "vitamin K deficiency bleeding."

  6. Dosage: The appropriate dosage of vitamin K supplements can vary depending on individual needs and medical conditions. Always follow the guidance of a healthcare provider or a registered dietitian when taking vitamin K supplements.

  7. Interactions: Vitamin K can interact with certain medications, including blood thinners like warfarin. If you are taking medications, it's crucial to inform your healthcare provider about any vitamin K supplements to ensure they do not interfere with your treatment plan.

  8. Safety: When taken at recommended doses, vitamin K supplements are generally considered safe for most people. However, excessive intake of vitamin K from supplements is usually not recommended, as it can lead to side effects.

  9. Special Considerations: Pregnant and breastfeeding women, as well as people with malabsorption disorders (conditions that affect nutrient absorption in the digestive tract), may have higher vitamin K requirements or be at risk of deficiency.They should consult with a healthcare provider regarding their vitamin K needs.

In summary, vitamin K supplements are used to address specific health concerns related to blood clotting and bone health. It's essential to use them under the guidance of a healthcare professional and to be aware of potential interactions with medications if you are taking them. As with any dietary supplement, a balanced diet rich in vitamins and minerals from natural food sources is generally recommended as the first approach to meeting nutritional needs.

User questions & answers

Question: are these vegan
Answer: Contains gelatin so not vegan.
Question: Is this product gluten free
Answer: I don't really know. I suggest that you contact the company because they are in the best situation to give you details of the ingredients. I am not allergic to gluten so this is a good thing. One thing I might suggest is that if you are not allergic to gluten then removing gluten from your diet is not worth the effort. In fact, you may accidentally malnourish yourself because of other essential ingredients that are removed when removing gluten. Take some time to research this on the Internet. Sincerely, Joe
Question: Kindly what is the exact number of vitamin k2 mk
Answer: K-2 menatetrenone 400 mcg, k-2 menaquinone 50 mcg, vitamin K-1 50 mcg. That is how it reads on bottle.
Question: I dont see number of mcg anywhere in the listing? can anyone share that please? i mean i can not buy unless it says how much vit k2 is in each dose
Answer: It says it on the front and back label. The back label is more detailed: 100 mcg of K1 and 450 mcg of K2, a combo of two forms of K2. Hope this helps!

Heart

Maintaining your heart is crucial, no matter what stage of life we are in, no matter where we live, no matter the life we lead.

By promoting the body’s calcium balance, vitamin K supports the vascular system, which depends on the heart.

Arterial Support

Vitamin K supports normal function of the protein MGP, which regulates how calcium interacts with your arterial walls.

Vitamin K helps maintain an already-normal calcium balance in your arteries.

Bone Support

Maintain strong bones with a nutritious diet, regular exercise and vitamin K.

By facilitating the incorporation of calcium into your bones, vitamin K helps maintain bone density, essential to whole-body wellness.

Get Four Biologically Active Forms of K

Super K provides THREE kinds of vitamin K: vitamin K1 and two forms of K2, menaquinone-4 (MK-4) and menaquinone-7 (MK-7).

The most common form of vitamin K, known as K1, is tightly bound to plant cells in leafy green vegetables, but vitamin K from these sources may be poorly absorbed.

Vitamin K2, found in small amounts in cheese, egg yolks and some meats, has been found to be up to eight times more bioavailable than K1 and to remain active in the body for a longer period of time.

Our MK-7 is made from an innovative bio-fermentation process which helps it stay available in the body for up to 48 hours and at much higher levels.

So taking Super K is a good way to make sure you’re getting enough of this essential nutrient for your bones and heart.

User questions & answers

Question: Have these pills been to a 3rd party lab for purity evaluation and potency? If so can the report please be provided
Answer: Vitamin K2 works synergistically with vitamin D3 to keep calcium out of your arteries and move it into where it needs to be -- your bones.
Question: Are there any carbs or sugar in this product? Thks
Answer: Hello, The Cholecalciferol we use is from Lichen, NOT sheep's wool, so yes our product is indeed Vegan. Our product is Vegan Certified from the Vegan Society. Thank you, Sports Research
Question: What is k
Answer: I found this on HealthCentral.com website: Vitamin D2 is the form of D that is found in fortified foods like milk, juices or cereals and D3 is the form that is synthesized by the skin when it's exposed to the sun or (ultraviolet light/UVB). D2 (ergocalciferol) can be found, in some plants/fungus. D3 (cholecalciferol) is the sunlight form, and can also be obtained from animals that manufactured it through their skin, like that in fish liver. Since the body can produce this it's actually considered a hormone and not a vitamin. D regulates calcium and phosphorus in the body.Some feel that D3 is more effective in humans than D2. D3 can be obtained after 10-15 minutes of sun exposure (without sunscreen) and is recommended 3-4 times a week. For those that can't get this sun exposure, supplements are a recommended substitute. The current RDA on D3 is 1,000 IU's a day for those over the age of 20.
Question: One of the ingredients, cholecalciferol, is derived from sheep, so is this actually not vegan
Answer: the gel caps are about 3/8" long by 1/4" thick--quite small. They are "football-shaped," which also helps them go down easily, and gel caps are always easier to swallow than coated pills (at least for me). I have a friend who also has troubles swallowing large pills, and she takes these and is perfectly fine with them.

User questions & answers

Question: What source is the K from? Glad it is not from soy but I cant have chic peas either
Answer: menaquinone
Question: what is the iu of the d
Answer: 5000 IU of D3 and 90 mcg of K2
Question: I have read that since D3 is oil soluble, it should be taken with oil. Is that true? Does this product contain oil to aid absorption if this is true
Answer: Always take oil-soluble vitamins and supplements WITH MEALS (up to 1/2 hour before and 2 hours after), which usually stimulate bile discharge. The "softgel" D or K supps in which those nutrients are dissolved in another oil do not provide enough total oil to make them good substitutes for this practice, meaning this Bronson product is perfectly adequate
Question: The front of the bottle says vitamin k2 as mk-7, but the supplement facts says vitamin k2 as menaquinone - which in mk-4. which is it
Answer: The FDA does not govern marketing statements. Bronson states the product contains 90 mcg MK7. But the ingredient label plainly reads menaquinone which could be MK 4 , MK 7, 8, or 9. As there is no FDA approved statement for MK7 I cannot support this product until Bronson clarifies the label. I just cancelled my order.

Bronson Vitamin K2 (MK7) with D3 Supplement - Vitamin D & K Complex Premium Non GMO & Gluten Free Formula

Bronson’s Vitamin K2 + D3 provides just the right amount of each essential vitamin to maximize their benefits to your bones and heart. No more, no less. Vitamin D (specifically D3, the form of vitamin D you get from the sun) is essential for properly absorbing the calcium we all know is so important as we age. Without D3, you may be missing out on benefits from the calcium in your diet. Most people start taking vitamin D3 after they experience signs of deficiency. You may have heard that D3 shouldn’t be taken alone–and it’s true! Let us explain. While vitamin D ensures that calcium is absorbed, vitamin K2 (specifically as MK-7, the most bioavailable form) is purported to direct the calcium into the bones and out of the bloodstream and arteries, which helps promote both bone mineral density and arterial flexibility. Vitamin K2 also helps synthesize crucial bone proteins, which allows vitamin K2 to further support healthy bone metabolism. Bottom line, vitamins K2 & D3 are truly the perfect pair. If you’re serio s about supporting healthy bones and a healthy heart, experience the benefits of Bronson’s Vitamin K2 + D3!

The Perfect Pair

Vitamins K2 & D3 were simply meant to be together. Most people know the benefits of vitamin D, but many don’t realize that vitamin D NEEDS vitamin K2 to maximize its benefits.

This formula not only promotes the proper absorption of calcium with D3, but it also promotes arterial flexibility.

We want the best when it comes to our food - clean, organic, and non-GMO. Why would we want anything different for our vitamins and supplements?

We are fanatical about food. We’re different that way. Whether we’re making a vitamin, or a probiotic, or a protein powder, we always start with real foods and these (foods) provide our formulas the power to be their best. We’re different that way, too. The synthetically created, chemical “breakthroughs” from huge commercial laboratories around the world are not for us.

As fanatical as we are over what goes into our products, we are even more obsessed about the things we keep out of them. We hate those synthetic chemicals that most companies use to make their products. This stuff makes machines work faster, and helps factories churn out super-sized containers at higher “efficiency.” Well, while the other guys spend their time preoccupied with their efficiency, we’re uncompromising about your health. Slow it down, make it by hand, grow it in rich organic non-GMO soil with enough sun, air, water and time for it to be its best. Harvest it when ready. Treat it with care. Turn it into a power-packed nutritious food supplement. That’s what we are about.

The Science of Whole Food

Your body was created to eat, process, and derive its nutrition from food—real, healthy food. So, when we create our products, we start by looking at food. What is the “good stuff” in the highest quality food that we are missing in our diets? Which of those foods have the greatest potential to impact—and empower—extraordinary health?

Clean is healthy

We start with what goes IN our products—true, whole food ingredients. But we don’t stop there. We also pay very close attention to what we keep OUT of them. And once again, we look at food—real nutrition food. When is the last time you picked up an apple, turned to read the ingredients, and saw a list of chemicals? If it’s not in your food, then we don’t want it in our supplements.

Traceability

Traceability is key to what makes Garden of Life’s products so special. Traceability starts with knowing where each and every ingredient in our products comes from and getting to know each and every source: where it’s grown; the farming practices; how they pay and treat the farm workers—everything. That’s why it’s so important to start with Certified USDA Organic and Non-GMO Project Verified fruits and vegetables that are grown without these chemicals. We want to get the good stuff from foods that are grown without any of the bad stuff.

User questions & answers

Question: Dr recommended 1000 mcg k2, but in reviewing MK-4 and MK-7 I think I need the MK-7. Haven't found it in 1000 mcg. Can you help? The NOW bottle that comes up on Amazon is not 1000, it is 100 mcg
Answer: Just finished reading about vitamin K and all the different types from 'Vitamin K2 and the Calcium Paradox'. Excellent book I must say. Your doctor must have been refering to MK-4 version of Vitamin K2 which has a half life of 1 hour i.e. you have 1/2 of amoun ingested after 1 hour, so you definitely need a lot. The MK-7 version of vitamin K2 has a much longer half life and hence you don't need as much. Today's medicare and doctors are extremely ignorant unfortunately.
Question: Is this a capsule or pill
Answer: Capsule
Question: i do not understand is why it says it alfalfa? is that literally all it is? just ground up alfalfa?? i see nothing to suggest other than alfalfa
Answer: It does not just say alfalfa it says Vitamin C, Vitamin K2 (as menaquinone 4) and alfalfa powder. Alfalfa is a source of vitamins A, C, E, and K4; and minerals calcium, potassium, phosphorous, and iron.
Question: I am wondering if this is MK-4, MK-7, a mix or something else entirely
Answer: I had to call NOW to find out. I thought it was MK-7 but found out that it was MK-4. Which is fine except you need to take more of MK-4 to get the benefits. They actually also sell a product that has MK-7 written on it. As they told me on the phone, their products are MK-4 unless specifically mentioned on the label. I am happy with NOW; I have confidence in their products.

User questions & answers

Question: What, exactly, is 120 mg of veg/fruit juice supposed to do
Answer: Your question is pretty ambiguous, but I will make a guess. I think that you are wondering what the 120 mg of organic fruit and vegetable blend is doing in a vitamin supplement. The answer to that is pretty easy. The very, very, very best supplements on the market are food based. Why? Because there is NO manufactured chemical that can match the bioavailability of plants. Most of the vitamins on the market today are synthetic, and do not address any of the body's needs. They are cheap to produce, however, and consumers don't read up on the foods or supplements, so cheap supplements are purchased. The Peak Performance product you are asking about is food based nutrition, so the 120 mg of the fruit and vegetable blend is one of the reasons why this product is good quality and effective. I hope this helps!
Question: How large are the pills
Answer: Not very big. Taste like you know what.
Question: How many mcg's is this? It's not anywhere in this ad
Answer: The label states there is: 10mcg-K1 100 mcg-K2 as menaquinone 7 10 mcg-K2 as menaquinone 4 Which makes it to 120 mcg’s total

User questions & answers

Question: gow many mgs does each pill contain
Answer: 100 mcg is one tenth of a milligram for vit K2 and there is also 2 mg of vitamin C. Informed consumers would also want to take some Vit A and Vit D (a min of 2000 IU) along with plenty of Calcium and Magnesium in the diet or pills to have the Vit K do its work.
Question: The manufacturer produces 3 different forms of k2 mk-7. the question is why do they not specify clearly which form this is
Answer: This is not a common question, we don’t specify on our labels. The manufacturer of MenaQ7® makes 4 types: NOW offers the “Natural MK-7” fermented from chickpeas. Other products offered by the same producer include a second type made from soybeans (“Natto MK-7”), a third one that’s a nature-identical synthetic and not made from fermented beans (“PharmaPure MK-7”), and a fourth one that provides several isomers (MK-6, MK-7, and MK-9) derived from fermented chickpeas (“Full Spectrum K2).
Question: Are the pictures from two different bottles? Gelatin is absolutely not Vegetarian
Answer: The photographs in Amazon's listing are outdated. The ingredients in the capsules have changed, and so has the label. There is no provision here to attach photos, so I will have to describe the new label, and the new list of ingredients.The capsules now contain NO gelatin. On the new label, the ingredients are listed as follows: "Vitamin C (2mg), Vitamin K2 (100 mcg)(as Menaquinone-7)(MK-7)(from Non-GMO Natto); Other Ingredients: Rice Flour, Cellulose (capsule) and Silica. Contains soy. Not manufactured with wheat, gluten, milk, egg, fish, shellfish, or tree nut ingredients." Certified Kosher.The front of the label reads: "NOW Vitamin K-2; Supports Bone Health; 100 mcg; From Non-GMO Natto; Promotes Arterial Health; 60 Veg Capsules; A Dietary Supplement; Vegetarian/Vegan; GMP Quality Assured".As you can see from the ingredients and the "Vegetarian/Vegan" specifications on the label, NOW MK-7 capsules now contain no gelatin.Amazon really should change the photos associated with this product. I have updated photos and have sent feedback on the current images, along with an offer to provide updated photos of the product's new label.
Question: What's the difference between this and your other product that is just k-2, and this one if more expensive than the other
Answer: There are around 100 different forms of vitamin K-2 (within the Menaquinone family-each designated "MK-#") available. Thus, if a bottle of vitamin K2 does not designate that it is "K-2 MK-7", then the form of vitamin K2 is most likely MK-1 or MK-4, both of which are quite inexpensively manufactured synthetically. Also, MK-7 is: harvested from NATTO (MK-7 is naturally produced by the bacteria that grow on fermented soy beans aka: NATTO); about 20 times more efficient/effective than other forms of vitamin K-2; and, though the bottles may say "contains soy", we've never heard of anyone having a soy reaction to MK-7 because it is harvested from the bacteria from NATTO not the soy itself. Respectively, when we buy vitamin K-2, we only use MK-7.

  • Immune Booster: These two ingredients work together to strengthen your immunity. D3 plays a key role in activating an immune response to seek out foreign threats from invading your system.
  • Bone Health Support: Many people already know the benefits of vitamin D, including bone health and immune system support, but vitamin D needs K2 in order to be most effective, especially when fighting a vitamin D deficiency.
  • Boosts Healthy Blood Circulation: By ensuring that calcium gets where it needs to go, K2 promotes a cleaner overall circulatory system, as the calcium is better able to get where it needs to go.
  • Heart Healthy Formula: By fighting against the “hardening of arteries” due to calcification, this formula is a great way to promote heart health.

User questions & answers

Question: Can you get vitamin K2 plus D3 in liquid form
Answer: Products do exist, but that is not what this product is. It is a soft gell.
Question: Two vitD capsules have 10000Iu then
Answer: 5,000+5,000=10,000 :) Yes, two capsules equal 10,000iu
Question: How much D3 iu and how much K2 (each separate, not the combined total) is in each capsule
Answer: K2 is 4000 IU and D3 is 5000 IU
Question: Is this product vegan? Wondering if the D3 is derived from lichens or lanolin
Answer: LiveWell Labs.... A suggestion...you might want to explain how the lanolin is processed so that people don't think this is an unnatural source of D3.. I had to look it up because, truthfully, I had no idea how common this derivative is; I thought the only true resource was from lichen or fish oil. A quick overview: when scientists create vitamin D from lanolin with the help of ultraviolet light, they partially mimic the natural process in your body that produces vitamin D when you expose your skin to sunlight. Both processes produce vitamin D-3, and fish oil also contains this form of the vitamin. Both synthesized D-3 and D-3 from food act the same way in your body, according to the National Institutes of Health's Office of Dietary Supplements. They also have slight chemical differences from another form of the vitamin called vitamin D-2, which comes from plants or plant-based sources. Now that I know this is not a "weird" source of D3, I'll be purchasing this product to try....

The Science:

Calcium is essential to strong bones, but calcium is also released by your bones into the bloodstream to help your heart. Unfortunately, unless there is vitamin K2 present, this calcium can end up settling inside of arteries and blood vessels, forming potentially dangerous deposits.

Vitamins D3 and K2 function in concert during supplementation. The D3 and K2 help the body produce and activate Matrix GLA Protein (MGP), which forms along arterial lining and helps protect it from the formation of calcium deposits.
