Vitamin K3: What You Need to Know

Vitamin K3, also known as menadione, is a synthetic form of vitamin K that was once used in supplements. However, due to potential toxicity risks, its use has declined, and most countries now recommend natural forms like vitamin K1 and vitamin K2 instead.

The Role of Vitamin K in the Body

Vitamin K is essential for:

✅ Blood Clotting – It activates proteins that help your blood clot properly.
✅ Bone Health – It helps regulate calcium and supports strong bones.

There are two natural forms of vitamin K:

• • Vitamin K1 – Found in leafy greens like spinach, kale, and broccoli.
  • Vitamin K2 – Found in fermented foods, dairy, and animal-based products. It is also produced by gut bacteria.

Why Vitamin K3 is No Longer Recommended

While vitamin K3 was once used in supplements, research has linked it to potential liver toxicity and other health risks. Because of these concerns, experts now recommend using safer, natural forms like vitamin K1 and K2.

The Best Way to Get Vitamin K

For most people, the best way to get enough vitamin K is through a balanced diet rich in natural sources:

🥬 Leafy greens (spinach, kale, broccoli)
🧀 Dairy products
🍗 Animal-based foods (eggs, liver, fish)
🍶 Fermented foods (natto, cheese)

If supplementation is necessary, always choose vitamin K1 or K2 and consult a healthcare professional to determine the best option for your needs.

Final Thoughts

Vitamin K is essential for your health, but when it comes to supplementation, natural is best. Stick to dietary sources or safe forms like K1 and K2 to support your body's vital functions safely and effectively.
