Vitamin K app for iPhone and iPad

IMPORTANT: Before buying this app, consider the new apps that covers Vitamin K: INR Assist. It provides the same functionality including creating custom foods, changing the color scale, and all items in the USDA database instead of just a select percentage. The only difference between these new apps is labeling and documentation, so you just need one.

Vitamin K is one of 10 iNutrient apps based on the USDA National Nutrient Database. The others include:

◉ iCarbs (Carbohydrates)
◉ iCholesterol (Dietary Cholesterol)
◉ iFiber (Fiber)
◉ iKals (Calories)
◉ iPotassium (Potassium)
◉ iProteins (Proteins)
◉ iSatFat (Saturated Fat)
◉ iSodium (Sodium)
◉ iSugars (Sugars)

Users can record their intake for any food. The information is maintained for one year and is presented in reverse chronological order grouped by day, so the latest data is presented first in the list. Editing allows for: 1) changing the number of servings; 2) changing the date; and 3) deleting records. Individual Intake Items can be copied to the current day, and all Intake Items for a single day can be copied to the current day.

If you take blood thinning medications like Coumadin(R) or Warfarin, then this is an app you will truly make use of on a regular basis.

"If you or a loved one is on Warfarin, this app is a fantastic resource to have on hand to know what foods are high in vitamin K. The foods are arranged alphabetically and are color-coded to help quickly identify how much vitamin K the particular food on interest contains. Highly recommended!

I just wanted to thank you for including endive in your latest update, v1.2, as you said you would. This is such a great app! Thanks for making it and keeping it updated! Its such a great resource for me!" -- tsd707

The Vitamin K app provides information about foods and how they are rated for Vitamin K content. This is provided as a means to assist in deciding which foods to eat if you are using blood thinning medications such as Coumadin or Warfarin. The food servings are rated from NO Vitamin K all the way up 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)
- Light Green = Rated MODERATELY LOW in Vitamin K (10.0 - 14.9 msg)
- Green = Rated LOW in Vitamin K (5.0 - 9.9 mcg)
- Cyan = Rated VERY LOW in Vitamin K (0.1 - 4.9 mcg)
- White = Rated EXTREMELY LOW in Vitamin K (0.0 mcg)
