Homocystinuria diet tracker

Classical homocystinuria (CBS deficiency). Also called HCU and cystathionine beta-synthase deficiency.

In classical homocystinuria the body can’t process methionine normally. For many people the diet limits methionine through a low-protein diet with a methionine-free formula.

Phebe counts methionine in milligrams for every food, beside protein and cystine, with a daily target for each.

Your clinic sets your targets. Phebe does the counting.

What Phebe counts

  • methionine
  • protein
  • cystine

Plus calories, macros, minerals, vitamins and every other amino acid.

How Phebe counts

  • Search the food database, scan a barcode, or photograph a nutrition label.
  • Weigh a portion on a Bluetooth kitchen scale, and the grams go straight into the entry.
  • Set a daily target for each nutrient you count, and see what is left today.
  • Log favorites in one tap, and build a recipe once to log the dish.
  • Start on your phone with no account. A free account adds the web app at app.phebe.life.
