What potassium supports
Potassium helps maintain fluid balance in the body and is commonly considered in wellness plans related to muscle function, post-exercise recovery, and managing dietary sodium intake. It can also be relevant for those tracking minerals more closely, such as athletes or people with higher sweat losses. Always check the label for the total potassium per daily serving, and consider intake from foods such as bananas, potatoes, beans and leafy greens.
How to choose a product
- Format: tablets or capsules to match your daily routine
- Strength: compare mg per serving and recommended use
- Pairing: often combined with magnesium, calcium and vitamin D
- Suitability: check allergens, vegan/vegetarian notes and additives
If you have kidney concerns, take medication (including diuretics), or are pregnant, speak with a pharmacist or GP before supplementing. Use as directed and do not exceed the stated recommended daily dose.
