How it works

  • It is estimated that many Americans do not get enough K2 through their diet, yet this vitamin is crucial for strong bones, helping calcium and other minerals to bind into the bone matrix. 
  • By regulating proper calcium absorption, K2 helps diminish calcification, supporting your heart health. 
  • Our K2 (MK7) is sourced from Natto, a traditional Japanese fermented soybean product, which is the highest food source of natural K2 (MK7). 
  • The process of fermentation removes soy from the product, and produces vegan, soy-free, all-trans, bioactive K2 (MK7). 
  • To support bone and heart health as well as aid calcium absorption, try this easy-to-take unflavored liquid.


Important Message from MaryRuth's

Important: We genuinely care about all our customers, which is why we always suggest consulting with a physician or healthcare professional before starting any health supplement. Since all bodies are different, an individual’s nutrient needs are unique to their body. As such, results may vary. Children under 14, seniors over 65, those pregnant and/or lactating, those who suspect a medical condition and those who are taking any medications should always consult with a physician or healthcare professional prior to use. Discontinue use if any negative reaction occurs. 

How to take

Suggested Use: This product was formulated for ages 4+. Shake gently before use. Once daily, take directly by mouth. Use the following dosage chart to assess dosage or dose as recommended by physician or healthcare professional:

  • Children (4-13 Years): Up to 14 Drops (33 mcg)
  • Adults (14+ Years): Up to 43 Drops (100 mcg)
  • Pregnant/Lactating: Up to 43 Drops (100 mcg)

Our K2 is sourced from Natto, a traditional Japanese food made from fermented soybeans. Natto is the highest natural food source of K2! The K2 is extracted, making this a soy-free product.


In order to make the best health decisions possible for your child, we always recommend speaking with your pediatrician, physician, or healthcare professional to help determine the best dose for your child.

Keep out of reach of children in case of accidental overdose or choking.

Store in a cool, dry place.

Have A Question? Great, Ask Us!

Really. We are here to answer any question you may have.

Why is there no daily value for Vitamin K on the supplement fact panel?

Due to changes implemented by the FDA, which now excludes K2 (menaquinones) are being counted toward the daily value of vitamin K, we no longer include daily values on our label for vitamin K2. Nevertheless, K2 (MK7) remains important for bone and heart health.

How do I know what an appropriate dose is when there are no recommended daily values?

Having no FDA recommendations for daily intake can make it hard to know what an appropriate dose might be! Though suggestions for intake vary, it has been shown that K2 MK-7 has greater bioavailability than other forms of Vitamin K, higher doses support bone health, and toxicity poses little risk. Ultimately, in order to make the best health decisions possible for you and your family, we recommend speaking with your physician or healthcare professional to determine what dose is best.

Can these K2 drops be used in place of the newborn Vitamin K shot?

To clarify, MaryRuth's Vitamin K2 is a plant-based, bioactive form of MK7, which is different from the Vitamin K injection shot offered at the hospitals in the US, typically 0.5–1 mg of vitamin K1 administered shortly after birth. If you are still interested in giving our K2 (MK7) to your child(ren), we would suggest you see your physician, pediatrician or healthcare professional and have them assist you in determining if the product is suitable for your child(ren). If it is, ask your healthcare professional to assess what the accurate dosage would be for your child. Each child is unique and different, and we want to make sure that they receive the best care possible!

Saving lives?
K2 (with D3 and some fat, eg. olive oil or butter) is said to move calcium from soft tissues (arteries, heart valves, etc) to bones and teeth. No, calcium by itself does not go to bones and may create problems!
K2 drops w/olive oil seems to be working just right. thank you! :)
