VITAMIN K
Overview
Vitamin K is a fat-soluble vitamin that helps your blood clot properly. This means it plays an important role in stopping bleeding when you get a cut or injury. It also helps keep your bones strong and healthy. You can find it in green leafy vegetables like spinach, broccoli, and kale.
Classification
Vitamin K is part of the fat-soluble vitamin group, which means it dissolves in fat and gets stored in the body.
There are two main types:
Vitamin K1 (found in plants, especially leafy greens)
Vitamin K2 (found in animal foods and fermented products like cheese or natto)
Uses
Helps blood clot to stop bleeding
Supports bone strength and growth
May help prevent calcium buildup in blood vessels (which can be harmful to the heart)
Given to newborns to prevent bleeding problems
How It Works
Vitamin K helps the body make proteins that are needed for blood clotting and bone building. Without enough Vitamin K, your blood may not clot well, and your bones may become weaker over time.
Dosage
As prescribed by your doctor.
Side effects
Vitamin K from food is generally safe. Side effects are rare, but may include (mainly from supplements or injections):
Stomach upset or cramps
Unusual taste in the mouth
Allergic reaction (very rare – rash, itching, swelling)
Injection side effects: redness, pain, or swelling at the site
Precautions
If you’re on blood thinners (like warfarin), you need to watch your Vitamin K intake
Too much from food usually isn’t harmful, but high-dose supplements should only be taken if prescribed
People with liver problems or digestive issues may need special guidance
Pregnant or breastfeeding women should ask a doctor before using supplements
