I eat 2.3 to 3 grams of potassium daily (the RDA is 4.7). Do you think this amount is enough for the deficiency to resolve on its own, or do I need to improve my diet?
I get about 30 minutes of moderate intensity exercise every day. Sometimes I have muscle spasms/twitches randomly or repeatedly in a muscle.
My magnesium, calcium and sodium intake is about ok.
Calculating one's intake can give some indication, but isn't accurate enough about possible sufficiency or deficiency. Due to varying metabolism and synergisms or antagonisms.
For example suffer from severe muscle cramps due to long term magnesium deficiency despite getting about 600 mg/d of magnesium from diet. Only orally supplementing an additional 2000 mg/d of elemental Mg ceased the muscle cramps. However, even after years serum and whole blood Mg haven't improved, hair tissue mineral analysis just a bit.
Also supplement with either powdered potassium bicarbonate or citrate 3 times a day dissolved in water, which gives about 2 g of elemental potassium per day. Each is different.
