When choosing the best preparation with magnesium and potassium, you should first of all be guided by the compound that is contained in the preparation, namely - it is to be well absorbed. Magnesium is best absorbed from organic salts, e.g. citrate, lactate, aspartate, potassium is absorbed well from both organic and inorganic connections, e.g. as potassium chloride, so it does not matter much. Preparations containing in the composition of well-absorbed magnesium and potassium in the form of a drug are, for example, Aspargin, Aspartate Magnokal, in the form of supplements are, for example, PotazekMag, Magnesium B6 Contraction, Katelin Contraction.
