Vitamin K Oil is one of the most underrated yet powerful oils in the wellness and skincare world. While vitamins like C and E often steal the spotlight, vitamin K plays a crucial role in blood clotting, bone metabolism, and skin repair. In oil form, it becomes especially popular for topical applications, helping with bruises, dark circles, scars, and skin healing.
In this guide, you will learn everything about Vitamin K Oil — from its nutrition profile and science-backed health benefits to dosage, side effects, storage, and precautions.
What is Vitamin K Oil?
Vitamin K Oil is a fat-soluble vitamin formulation derived from vitamin K compounds, typically vitamin K1 (phylloquinone) or vitamin K2 (menaquinone), blended into a carrier oil for easier absorption and topical or oral use.
Vitamin K is naturally found in green leafy vegetables, fermented foods, and certain animal products. In oil form, it is concentrated and more bioavailable because vitamin K dissolves in fats. This makes it especially effective for skin applications and supplementation.
There are two main types used in oils:
- Vitamin K1 (Phylloquinone): Commonly used in topical skincare products.
- Vitamin K2 (Menaquinone): Often used in dietary supplements for bone and heart health.
Components of Vitamin K Oil
The nutritional profile varies depending on formulation, but here is a general overview per 1 ml (approximate values):
| Nutrient | Approximate Amount per 1 ml |
|---|---|
| Vitamin K1 or K2 | 100–1000 mcg (varies by brand) |
| Calories | 8–10 kcal |
| Total Fat | 1 g |
| Saturated Fat | Depends on carrier oil |
| Carbohydrates | 0 g |
| Protein | 0 g |
| Cholesterol | 0 mg |
Note: The exact concentration depends on whether the oil is diluted in coconut oil, olive oil, MCT oil, or another carrier.
