New Vitamin K iTunes App Provides Great Help for Coumadin/Warfarin Users

October 4, 2010 in Medical (E)

[] Revere, Massachusetts - Independent developer James Hollender today is pleased to announce the release of 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.

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 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
* Dark Red = Rated VERY HIGH in Vitamin K
* Red = Rated HIGH in Vitamin K
* Orange = Rated MODERATELY HIGH in Vitamin K
* Yellow = Rated MODERATE in Vitamin K
* Yellow-Green = Rated MODERATELY LOW in Vitamin K
* Green = Rated LOW in Vitamin K
* Cyan = Rated VERY LOW in Vitamin K
* White = Rated EXTREMELY LOW in Vitamin K

There are four tables listing foods:
* All Foods
* Foods rated Low in Vitamin K (0.0 - 9.9 mcg)
* Foods rated Moderate in Vitamin K (10.0 - 24.9 mcg)
* Foods rated High in Vitamin K (25.0 - 1146.6 mcg)

Selecting a food in any of the tables will display additional information including a detailed description of the food and, in some cases, a photograph of the item.

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, Fried" and "Fried Egg"). A few of these have as many as six searchable names.
