What would be the ratio of K2 I need to take if I take 5,000 daily units of Vit.D? My Vit.D blood level is at 73 now.
Thanks so much!
That’s great that you are at 73!
The standard ratio for vitmain K (K1/K2) is 100 mcg for every 1000 IU (now more commonly written as 25 mcg), but your individual needs may vary based on medications, diet, and genetics.
Best!

Yes, you can! Eating your greens is the easiest way, as long as you eat them regularly. Here is a good table of food sources, with their corresponding micrograms of vitamin K (source is Linus Pauling Institute):
Food | Serving | Phylloquinone (μg) |
---|---|---|
Kale, raw | 1 cup (chopped) | 472 |
Swiss chard, raw | 1 cup | 299 |
Parsley, raw | ¼ cup | 246 |
Broccoli, cooked | 1 cup (chopped) | 220 |
Spinach, raw | 1 cup | 145 |
Watercress, raw | 1 cup (chopped) | 85 |
Leaf lettuce (green), raw | 1 cup (shredded) | 46 |
