Potassium bicarbonate is a form of potassium available in a supplement form. It can be obtained in a tablet, capsule, liquid or powder. This supplement may be taken if you require more potassium in your diet due to a deficiency or another health condition. Potassium is an important mineral in your body that plays a role in proper heart, skeletal and muscle function. In addition to supplemental forms, potassium, the major component of the potassium bicarbonate supplement, can also be found in dietary sources.
Fruits And Vegetables
Fruits and vegetables are rich sources of potassium, the key component of potassium bicarbonate. Among the fruits, bananas and raisins are particularly rich sources. One medium banana supplies 422 mg of potassium, according to the Linus Pauling Institute 2. In comparison, 1 medium orange contains 237 mg of potassium, 1 medium tomato contains 292 mg of potassium and a 1/2 cup of raisins contains 598 mg of potassium. Vegetables also contain a good amount of potassium. One medium-baked potato, with skin, supplies your body with 926 mg of potassium, making this food a particularly rich source. A 1/2-cup serving of cooked spinach contains 422 mg of potassium and a 1/2 cup serving of cooked acorn squash contains 448 mg of potassium.

Nuts and seeds also contain a significant amount of potassium. A 1 oz. serving of almonds can supply your body with 200 mg of potassium, according to the Oregon State Linus Pauling Institute 2. A 1-oz. serving of sunflower seeds can supply you with 241 mg of potassium. Eating a daily serving of these foods as a snack or sprinkling them on salads may help boost your intake of potassium.

Animal Protein Foods
Although fruits and vegetables are the richest sources of potassium, some animal proteins can also be good sources. Potassium can be obtained in fish, such as flounder, salmon and cod, according to the University of Maryland Medical Center 1. Other animal protein sources include chicken and meats.
