Definition of Vitamin K
Vitamin K is a group of fat-soluble vitamins essential for blood clotting, bone metabolism, and regulating calcium levels in the body.
Forms of Vitamin K
There are two main forms:
(phylloquinone), also known as Vitamin K1, is a type of vitamin K found abundantly in leafy green vegetables. It plays a vital role in blood clotting, assisting in the production of proteins necessary for coagulation.
And Menaquinone, commonly referred to as Vitamin K2, encompasses a group of compounds found in animal products and fermented foods. It supports various bodily functions, including bone metabolism and cardiovascular health, by aiding in calcium regulation and utilization in the body.
Sources of Vitamin K
Here are the main sources of Vitamin K:
Vitamin K1 (Phylloquinone):
Leafy greens: Spinach, kale, collards, Swiss chard, broccoli
Vegetable oils: Soybean oil, canola oil, olive oil
Vitamin K2 (Menaquinones):
Fermented foods: Natto (Japanese fermented soybeans), cheese, sauerkraut
Animal products: Liver, meat, eggs
Both forms of Vitamin K play essential roles in blood clotting and bone health.
Certainly! Here are further sources of Vitamin K1 and K2:
Vitamin K1 (Phylloquinone):
Herbs: Parsley, basil, coriander (cilantro), thyme
Vegetables: Brussels sprouts, asparagus, green beans, cabbage, lettuce

Meat and Liver: Chicken, beef, pork, and their liver contain varying amounts of Vitamin K2.
Fish: Particularly Salmon.
Egg yolks: Contain small amounts of Vitamin K2.
Fermented Foods: Sauerkraut, kefir, miso, and tempeh also contain traces of Vitamin K2.
These foods offer essential Vitamin K1 and K2, crucial for blood clotting, bone health, and overall well-being.
Vitamin K1 (Phylloquinone):
Seeds: Chia seeds, pumpkin seeds, sunflower seeds.
Nuts: Cashews, almonds, pistachios.
Vegetables: Green peas, green peppers, cucumbers.
Fruits: Blueberries, figs, prunes.
Vitamin K2 (Menaquinones):
Nuts and Seeds: Cashews, pine nuts, sesame seeds.
Oils: Flaxseed oil, sesame oil.
Dairy Products: Butter, yogurt.
Meat Products: Salami, chicken sausage.
Other: Green tea, black tea.
These diverse sources can help in obtaining adequate Vitamin K1 and K2 for various bodily functions, including blood clotting, bone metabolism, and cardiovascular health.
Vitamin K1 (Phylloquinone):
Herbs and Spices: Sage, oregano, thyme, curry powder.
Leafy Greens: Mustard greens, turnip greens, dandelion greens.
Vegetables: Beet greens, leeks, okra.
Cruciferous Vegetables: Cauliflower, bok choy, Brussels sprouts.
Fruits: Blackberries, raspberries, strawberries.
Vitamin K2 (Menaquinones):
Japanese dishes: Sushi, particularly made with fermented soybeans or fish, can contribute to Vitamin K2 intake.
Nuts and Nut Butters: Hazelnuts, walnut butter.
Cheeses: Brie, Camembert, Cheddar.
Meats: Duck, turkey, lamb.
Fermented Beverages: Some kombucha varieties might contain trace amounts of Vitamin K2.
These additional sources provide a wider array of foods rich in both Vitamin K1 and K2, helping ensure a balanced intake of this essential nutrient.
Dali requirements of Vitamin K
The recommended daily intake of vitamin K varies by age and gender. For adults, the general guideline is around 90-120 micrograms (mcg) per day. However, these recommendations may differ based on individual health conditions and other factors. It's always advisable to consult a healthcare professional to determine the specific vitamin K requirements for your situation.
Certainly! Here's a breakdown of the recommended daily intake of vitamin K based on age and gender:
Infants:
0-6 months: 2.0 micrograms (mcg) per day
7-12 months: 2.5 mcg per day
Children:
1-3 years: 30 mcg per day
4-8 years: 55 mcg per day
9-13 years: 60 mcg per day
Adolescents and Adults:
Males 14-18 years: 75 mcg per day
Females 14-18 years: 75 mcg per day
Males 19 years and older: 120 mcg per day
Females 19 years and older: 90 mcg per day
These values represent general recommendations and might vary based on individual health conditions, medications, or other factors. It's advisable to consult a healthcare provider for personalized guidance on your vitamin K intake.
The role of Vitamin K
Vitamin K plays a crucial role in blood clotting, as it helps in the production of certain proteins necessary for coagulation. It also contributes to bone health by assisting in the regulation of calcium within the bones and blood. Additionally, it supports cardiovascular health and may have a role in other bodily functions like cell growth and maintenance.
K2 vitamin also has emerging research suggesting its potential benefits in skin health, cognitive function, and possibly anti-inflammatory effects.
Certainly! Vitamin K's functions extend to various bodily processes:
Cardiovascular Health: Beyond its role in blood clotting, Vitamin K might support heart health by preventing arterial calcification, thereby potentially reducing the risk of cardiovascular diseases.
Bone Metabolism: Apart from aiding in bone health by assisting in calcium regulation, Vitamin K could help in increasing bone density and reducing the risk of fractures, particularly in older adults.
Cell Growth Regulation: Some studies suggest that Vitamin K might have a role in regulating cell growth, which could have implications in cancer prevention and treatment. Research in this area is ongoing.
Brain Function: There's emerging research indicating that Vitamin K might play a role in brain health, potentially affecting cognitive function and reducing the risk of neurodegenerative diseases. Anti-inflammatory Properties: Vitamin K might have anti-inflammatory effects, impacting various inflammatory conditions in the body. This aspect is still under investigation.
It's important to maintain an adequate intake of Vitamin K through a balanced diet to support these functions and ensure overall health and well-being.
Blood Sugar Regulation: Some studies suggest that Vitamin K might contribute to better insulin sensitivity and glucose metabolism, potentially aiding in managing blood sugar levels.
Wound Healing: Vitamin K could have a role in supporting wound healing by promoting blood clotting, which is essential in the initial stages of the healing process.
Cancer Prevention: There is ongoing research exploring Vitamin K's potential role in reducing the risk of certain types of cancers, particularly in relation to its effects on cell growth and apoptosis (programmed cell death).
Immune System Support: Vitamin K might play a role in supporting the immune system's functions, although the specific mechanisms and impacts need further investigation.
Skin Health: Some studies suggest that Vitamin K, particularly in topical applications, might have benefits for skin conditions such as dark circles under the eyes, bruises, and certain skin irritations. However, more robust evidence is needed to confirm its efficacy in these areas.
Vitamin K's multifaceted roles make it an essential nutrient for overall health, but further research is necessary to fully understand the extent of its effects on these various bodily functions.
Vitamin K deficiency
Vitamin K deficiency occurs when the body doesn't have enough vitamin K, a fat-soluble vitamin crucial for blood clotting and bone health. Symptoms may include increased bleeding, easy bruising, nosebleeds, and heavy menstrual bleeding. Severe deficiency can lead to haemorrhages or weakened bones.
Treatment often involves dietary changes or supplements under medical guidance
