Pharmacist explains if potassium and magnesium supplementation is needed in winter

Potassium and magnesium supplementation may not be necessary in winter, according to pharmacist Giacomo Pisano. Deficiencies are unlikely in winter unless due to significant fluid loss from illness. Magnesium deficiency causes fatigue and muscle issues, while potassium deficiency is rare but dangerous for heart function. Pisano advises caution with mineral supplements, many being sugar-based. He recommends magnesium bisglycinate for better absorption and suggests consulting a pharmacist.
