Potassium is important for maintaining nerve function, muscle control and blood pressure. The U.S. Institute of Medicine (IOM) recommends consuming 4.7g (4,700mg) of potassium a day. The Daily Value (DV), set by the U.S. Food and Drug Administration, is 3,500mg of potassium per day. Wheat, oat and rice bran are high in potassium, and many cereals are fortified with potassium as well. Potassium is listed in milligrams per a 200-calorie serving.

Bran cereals contain the highest amount of potassium. Kretschmer Toasted Wheat Bran from Quaker Oats is the best source at nearly 1,300mg per 200-calorie serving, as listed by NutritionData.com. Kellogg's All-Bran with Extra Fiber, All-Bran Buds and All-Bran contain about 800 to 1,100mg of potassium. Post 100-Percent Bran Cereal, Post Bran Flakes, Ralston Enriched Bran Flakes and Malt-O-Meal High Fiber Bran Flakes also are good sources of potassium, with 300 to 660mg per 200 calories.
Adding raisins to bran cereal raises the calorie content and thus lessens the potassium content from wheat bran in a 200-calorie serving. Still, raisin bran is a good source of potassium. Cereals to consider include Raisin Bran from Kellogg's, General Mills, Malt-O-Meal and Post, with 320 to 390mg of potassium. Additionally, Kellogg's All-Bran Yogurt Bites contains about 305mg per 200 calories.
