Understanding Vitamin K
Vitamin K is a fat-soluble vitamin that plays a crucial role in blood clotting and bone health. People take Vitamin K to prevent Vitamin K deficiency, which can lead to excessive bleeding and an increased risk of osteoporosis.
Natural sources of Vitamin K include leafy greens, broccoli, and certain vegetable oils.
What is Vitamin K?
Vitamin K is a fat-soluble vitamin that plays a big role in helping blood clot. This means it helps stop bleeding when you get hurt. It’s also important for keeping your bones strong and healthy.
When people don’t have enough vitamin K, they can bleed too much or have weak bones.
Our bodies need this nutrient to make proteins that work in blood clotting and bone formation. There are two forms of vitamin K: vitamin K1, mostly from leafy green vegetables, and vitamin K2, found in meats, cheeses, and eggs.
Babies are born with low vitamin K levels, so they often get a shot to help them start right.

Why do people take Vitamin K?
People take Vitamin K because it helps stop too much bleeding. You could bleed even from a small cut without enough of this vitamin. Vitamin K has another big job – making bones strong.
Some people might break their bones less if they have more Vitamin K. New babies get a shot to keep them safe from bleeding that can happen when they don’t have enough.
Eating foods like spinach, kale, and broccoli gives your body Vitamin K, but sometimes not everyone eats enough greens. Then, they might need extra tablets or shots to stay healthy.
Our next topic will look at how much Vitamin K different people should take.

Recommended Dosage for Different Age Groups
Children (0-3 years) should receive two micrograms of Vitamin K daily, while children (4-8 years) may need a slightly higher dose of 55 micrograms daily. The recommended dosage for children aged 9-13 years is 60 micrograms daily, and teenagers (14-18 years) should aim for around 75 micrograms per day.
As for adults (19+ years), the recommended dosage is typically around 90 to 120 micrograms per day.
Children (0-3 years)
Babies need vitamin K for healthy blood clotting. Newborn babies should get a vitamin K injection or drops to prevent bleeding problems. Typically, babies receive two doses at birth and within 3-5 days after birth and another dose in the fourth week to ensure they have enough vitamin K.
This is crucial as newborns have lower levels of vitamin K in their bodies, and without enough of it, there’s a risk of hemorrhagic disease that can cause severe bleeding. Parents need to ensure their newborn receives these recommended doses.
Children (4-8 years)
Children aged 4-8 need about 55 micrograms of vitamin K daily to stay healthy. This can be obtained from broccoli, spinach, and other leafy greens. It’s important for their bone health and blood clotting.
In addition to vitamin K, children ages 4-8 also require 1,000-1,400 IU of vitamin D daily. Vitamin D is crucial for bone development and immune system function. Good sources of vitamin D include fortified milk, fatty fish like salmon or tuna, and egg yolks.
Ensuring your child gets enough vitamins K and D will support their growth and overall well-being in these formative years.
Children (9-13 years)
As children progress to the age range of 9-13 years, their recommended daily intake of vitamin K increases to 60 mcg. At this stage, parents and caregivers must ensure that the children consume a well-balanced diet that includes green leafy vegetables such as spinach, kale, and broccoli.
These foods provide essential nutrients and serve as natural sources of vitamin K necessary for healthy growth and development.
Ensuring that children aged 9-13 years get adequate vitamin K intake is crucial for supporting their overall health and well-being. By incorporating vitamin K-rich foods into their diet, parents can help maintain optimal levels of this vital nutrient in their child’s body during these formative years.
Teenagers (14-18 years)
During the teenage years, adolescents aged 14-18 should aim to consume 75 mcg of Vitamin K daily. Ensuring an adequate intake of this essential vitamin is crucial for maintaining overall health and well-being during this period of growth and development.
Teenagers can obtain their recommended daily dosage from various sources, such as leafy greens, broccoli, and other green vegetables. Teenagers need to pay attention to their Vitamin K intake and incorporate foods rich in this vitamin into their diet to support healthy bone growth and blood clotting.
Adolescents aged 14-18 need approximately 600 to 1,000 IU (15 to 25 μg) of Vitamin K daily. Maintaining a balanced diet that includes the recommended daily dosage will contribute significantly towards ensuring optimal health during these formative years.
Adults (19+ years)
Adults aged 19 and older should aim for a daily intake of 120 micrograms (mcg) of vitamin K for men and 90 mcg for women. The average daily vitamin K intake from foods for adults aged 20 and older is 122 mcg for women and 138 mcg for men.
Experts advise a reasonably constant dietary intake of vitamin K that meets current dietary recommendations (90-120 μg/day) for adults.
For adults, the Adequate Intake (AI) for vitamin K is estimated to ensure nutritional adequacy, varying based on age and sex. It’s essential to maintain an appropriate level of vitamin K through diet or supplements according to individual needs.
Risks of Taking Vitamin K
Potential side effects of taking Vitamin K include the risk of decreased effects of warfarin, major bleeding, life-threatening bleeding, and possible interactions with other medications.
It’s important to consult a healthcare provider before starting any new supplement regimen to ensure safety and effectiveness.
Potential side effects
Taking vitamin K supplements can lead to potential side effects, especially if not used correctly. Here are some possible side effects to be aware of:
- Interactions with Medications: Vitamin K can interact with certain medications like blood thinners, altering their effectiveness.
- Allergic Reactions: Some individuals may experience allergic reactions such as rash, itching, or difficulty breathing after taking vitamin K supplements.
- Digestive Issues: High doses of vitamin K can cause digestive problems like nausea, stomach upset, or diarrhea.
- Blood Clotting Issues: Excessive vitamin K intake can lead to abnormal blood clotting and increase the risk of blood clots forming

- Kidney Damage: Individuals with kidney disease should be cautious as excessive vitamin K can potentially harm the kidneys.
- Pain and Swelling at Injection Site: If administered via injection, pain, bruising, or swelling at the injection site can occur
Interactions with other medications
Potential side effects of taking Vitamin K should be carefully considered, especially when interacting with other medications. Some important medications that can interact with Vitamin K include:
- Warfarin (Coumadin), an oral anticoagulant used to slow blood clotting
- Antibiotics, particularly cephalosporins, which can reduce the absorption of Vitamin K in the body
- Anticoagulants and drugs for cancer, which can potentially result in dangerous interactions
- Aspirin, which may decrease the effectiveness of Vitamin K
- Other medications that affect blood clotting and coagulation
Final Thoughts
In conclusion, understanding the correct dosage of Vitamin K for different age groups is essential for maintaining good health. From infants to adults, each group has specific recommended dosages tailored to their needs.
It’s important to consult with a healthcare provider before starting any Vitamin K supplements, especially considering potential interactions with medications and their possible side effects.
