One surprising way we can deplete the body of electrolytes is through excessive water consumption. “People who drink three or more litres of water a day – who think they’re doing something good for their bodies – find that it actually leads to excessive urination and a subsequent loss of electrolytes,” says Stansbie. Another is a similar, seemingly healthy habit: “Those who avoid salt entirely are missing out on two essential electrolytes: sodium and chloride,” she notes.
What are the symptoms of low electrolytes?
Low electrolyte balance can manifest as:
- Fatigue
- Weakness
- Confusion
- Muscle spasms
- Nausea and vomiting
- Headaches
Is it good to drink electrolytes every day?
If you tend to eat a balanced, varied diet, then do you need to supplement with electrolytes? According to the experts, probably not. “While proper electrolyte balance is genuinely important for health and wellbeing, most people with normal diets and activity levels don’t need specialised supplements on a daily basis,” says nutritional neuroscientist Amy Reichelt. “Especially if your diet contains high levels of sodium chloride (table salt) or you don’t drink enough water.”
Even for those who exercise regularly, Reichelt takes a dim view of electrolyte supplements. “They provide convenient hydration for occasional needs such as if in a hot environment, people who sweat and exercise a lot, or if you have food poisoning or vomiting or diarrhoea. However, most prepackaged electrolyte supplements are expensive and can contain added sugars or artificial ingredients, and overuse could also lead to electrolyte imbalances.”
For women, there’s a compelling argument that supplementing with electrolytes can help with fatigue and muscular cramps caused by iron and electrolyte loss during menstruation. “Similarly, during menopause, symptoms like excessive sweating and night sweats can lead to shifts in electrolyte balance. In pregnancy, too, increased fluid needs can alter electrolyte levels, with magnesium being especially important to prevent leg cramps,” advises Dr Dallas.
When looking for a quality electrolyte supplement, Dr Dallas says to find one that contains a “mix of key minerals, such as sodium, potassium, calcium, magnesium, and chloride, to ensure proper hydration and mineral replenishment.” Beyond that, pick one with minimal artificial additives like sweeteners, flavours or colours.
How exercise affects electrolyte balance
Celebrity personal trainer Aimee Victoria Long says that the type, intensity and length of the exercise you do can affect the electrolyte balance in your body. “HIIT (high intensity interval training) usually results in significant sweating, which can make supplementing with electrolytes a good idea. It’ll help replenish minerals lost through sweating. Endurance sports and prolonged activities like running can also benefit from supplementation.”
If you don’t exercise regularly, or tend to stick to low-impact workouts like Pilates or yoga in cool environments, Long says not to worry too much. Instead, focus on adequate hydration and eating a balanced diet of vitamins, antioxidants, protein, healthy fats, complex carbohydrates and fibre.
Is there anyone who shouldn’t take electrolytes?
“Individuals with heart conditions, especially heart failure or hypertension, should avoid excessive sodium intake, as it can worsen fluid retention and blood pressure. People with Addison’s disease or other endocrine disorders may require careful monitoring of their electrolytes. Additionally, those on diuretics or medications that affect electrolyte levels should consult a healthcare provider before using supplements,” cautions Dr Dallas.
