Revere, Massachusetts – Independent developer James Hollender has released version 2.6 his Vitamin K app for iPhone, iPod touch and iPad. The Vitamin K app allows users to easily find out how much vitamin K there is in over 900 different foods which is critical in helping keep the effectiveness of their blood thinning medications working properly. The new version is updated for additional support with iOS 5.
Note: This is one of 8 Nutrient apps based on the USDA National Nutrient Database. The others include: iCals, iCarbs, iCholesterol, iFiber, iProteins, iSatFat and iSugars.
If you take blood thinning medications like Coumadin(R) or Warfarin (also known as Jantoven, Marfarin, Lawarin, Waran and Marevan), then this is an app you will truly make use of on a regular basis. Most lists providing information on the content of vitamin K (K1, K1D & K2) in foods generally contain only a limited number of foods, and often they don’t indicate the serving size. It is important to understand that the goal isn’t to not eat any foods with vitamin K, but rather to keep relatively constant the amount of vitamin K ingested each day so the amount of Coumadin(R) prescribed can work effectively. This can be different for every person using blood thinning medications, and this is why doctors require occasional blood tests as they indicate if the dosage needs to be adjusted.
All too often we hear that you should stay away from dark green leafy vegetables if you are using Coumadin(R), but there are a host of other foods containing vitamin K. Even the dark green leafy vegetables contain varying amounts of vitamin K. Further, each food has its own characteristics and sometimes whether it is fresh, frozen or canned can make a difference in the vitamin K content. The important thing to understand is you may be inadvertently ingesting something which you think doesn’t contain any vitamin K when in fact it does. A good example would be carrots which contain varying amounts of vitamin K. A single baby carrot has only 0.9 mcg (very low) while a cup of canned carrot juice contains 36.6 mcg (high).
The Vitamin K app provides information about foods and how they are rated for Vitamin K content based on preparation and serving sizes. This is provided as a means to assist in deciding which foods to eat if you are using blood thinning medications such as Coumadin(R) or Warfarin. The foods are rated from EXTREMELY LOW to EXTREMELY HIGH in Vitamin K. The following colors help readily identify which is which:
* Black = Rated EXTREMELY HIGH in Vitamin K (700.0 – 1146.6 mcg)
* Dark Red = Rated VERY HIGH in Vitamin K (300.0 – 699.9 mcg)
* Red = Rated HIGH in Vitamin K (25.0 – 299.9 mcg)
* Orange = Rated MODERATELY HIGH in Vitamin K (20.0 – 24.9 mcg)
* Yellow = Rated MODERATE in Vitamin K (15.0 – 19.9 mcg)
* Yellow-Green = Rated MODERATELY LOW in Vitamin K (10.0 – 14.9 mcg)
* Green = Rated LOW in Vitamin K (5.0 – 9.0 mcg)
* Cyan = Rated VERY LOW in Vitamin K (0.1 – 4.9 mcg)
* White = Rated EXTREMELY LOW in Vitamin K (less than 0.1 mcg)
There are eight tables listing foods:
* All Foods
* Fast Foods
* Fruits & Vegetables
* Meat, Fish & Shellfish
* Dairy & Egg
* Cereal Grains & Pasta
The All Foods table includes a search capability to quickly find food servings you are interested in.
Selecting an item in any of the tables will display pertinent information about the selected food serving:
* Food Title
* Weight in grams
* Common Measure, e.g., 1/2 cup, etc.
* Vitamin K Content (overall)
* Vitamin K1 Content
* Vitamin K1D Content

* USDA National Nutrient Database for Standard Reference ID
Information is derived from the USDA National Nutrient Database for Standard Reference: Vitamin K Content of Selected Foods per Common Measure. There are currently over 930 different foods included, searchable using approximately 2,500 names (some foods are known by different names or how they are prepared, e.g., “Egg, Scrambled” and “Scrambled Egg”). A few of these have as many as six searchable names. The Info page provides additional information about Vitamin K:
