Whether milk is considered high in Vitamin K depends on the type of milk and what is considered "high." Full-fat milk contains a moderate amount of Vitamin K, while reduced-fat and fat-free milk contain significantly less.
Here's a breakdown based on a study that examined the Vitamin K content of different types of milk:
| Type of Milk | Vitamin K Content (µg/100 g) | Percentage relative to full-fat |
|---|---|---|
| Full-Fat Milk (4% fat) | 38.1 ± 8.6 | 100% |
| 2%-Fat Milk | 19.4 ± 7.7 | ~51% |
| 1%-Fat Milk | 12.9 ± 2.0 | ~34% |
| Nonfat Milk | 7.7 ± 2.9 | ~20% |
As the reference data indicates, reduced-fat or fat-free dairy products contained approximately 5–22% of the vitamin K found in full-fat equivalents. Therefore, while full-fat milk provides a reasonable amount of Vitamin K, lower-fat options provide much less. Whether or not full-fat milk is "high" in Vitamin K is subjective and would depend on individual dietary needs and recommendations.
