Potassium works at cell level
It’s important to know which foods contain potassium, and how much, because potassium works at cell level. All cells have sodium/potassium ion pumps, but they are most active in nerve cells. When your nerves transmit a message like, Hot, Cold, Let’s move, Pick up the chocolate bar, etc. they do it by moving sodium and potassium ions in and out via sodium/potassium pumps. It’s for this basic physiological reason that foods high in salt/sodium can upset the process and cause serious health problems.
To meet your body’s potassium requirements, you need about 4,700 mg of potassium a day. But, when you’ve had low vitamin B12 for a period of time, and if your blood cells have been affected (anemia is a common symptom of low vitamin B12 levels), then when you begin replacing vitamin B12 your blood cells begin dividing and returning to a normal size. That takes a lot of more potassium than you would otherwise need.
If your diet is low in potassium, then the added demand when your blood cells begin returning to normal may cause unpleasant side affects like loss of strength and even muscle spasms.

If you know what foods are high in potassium, you can restore your B12 levels without unpleasant side effects, as long as you eat the foods high in potassium.
Equally, if you use a lot of vitamin B12 over a period of time, for instance I used 25 mg or more a day for more than five years, you may begin to have side effects, like muscle spasms, from the cobalt. Basically, vitamin B12 is cobalt in extremely tiny amounts. Cobalt is a heavy metal.
When I began adding Maca (rich in potassium) to my daily coffee, the spasms became fewer and less painful. Now I regularly eat peanut butter, dishes with tomato paste, and potatoes and I no longer have the problem.
If I had known earlier about the effect of B12 healing blood cells I could have adjusted my diet long ago.

The FDA has determined that foods that contain at least 350 milligrams of potassium can bear the following label: “Diets containing foods that are good sources of potassium and low in sodium may reduce the risk of high blood pressure and stroke.”
Potassium helps protect against Kidney Stones
A study of more than 45,000 men followed for four years found that men whose potassium intake averaged more than 4,042 mg/day were only half as likely to develop symptomatic kidney stones as men whose intake averaged less than 2,895 mg per day.

Potassium helps keep pH high and osteoporosis low
Potassium-rich foods, like fruits and vegetables, are rich in precursors to bicarbonate ions, which buffer acids in the body.
The modern Western diet tends to be low in sources of alkali (fruits and vegetables) and high in sources of acid (fish, meats, and cheeses).
When the quantity of bicarbonate ions is too low to maintain normal pH, the body can mobilize alkaline calcium salts from bone in order to neutralize acids consumed in the diet and generated by metabolism.
Increased consumption of fruits and vegetables reduces the net acid content of the diet and may preserve calcium in bones, which might otherwise be mobilized to maintain normal pH.

Potassium helps protect against Stroke
Study of more than 43,000 men followed for eight years found that men in the top quintile (1/5) of dietary potassium intake (median intake, 4,300 mg/day) were only 62% as likely to have a stroke than those in the lowest quintile of potassium intake (median intake, 2,400 mg/day).

Potassium helps Significantly lower high blood pressure
Data on more than 17,000 adults who participated in the Third National Health and Nutrition Examination Survey (NHANES III) indicated that higher dietary potassium intakes were associated with significantly lower blood pressures.
