A Dietitian's pick: Our favourite electrolytes for POTS in Australia, 2026 update
What is POTS?
Postural Orthostatic Tachycardia Syndrome (POTS) is a condition that affects the Autonomic Nervous System, which is a branch of the nervous system regulating automatic bodily functions.
People with POTS experience a dysregulation in the autonomic nervous system (Dysautonomia), resulting in increased ‘sympathetic tone’, or an elevated fight-flight-freeze response. This can result in a wide range of systemic symptoms like dizziness, rapid heartbeat, nausea and gut motility changes, brain fog, temperature sensitivity and fatigue.
Common triggers include orthostatic changes (e.g. moving from lying down and standing up or prolonged standing), warm environments, allergies, eating, dehydration, sex hormone changes, and more.
In 2026, we are still learning about what exactly causes POTS. It’s well understood that POTS commonly co-exists with conditions like Ehlers-Danlos Syndromes and Hypermobility Spectrum Disorder, Myalgic Encephalomyelitis (ME/CFS), Long COVID, and Mast Cell Activation Syndrome.
Why sodium and fluid are the cornerstones of POTS management
Proper hydration and electrolyte intake are crucial for managing POTS symptoms, in order to regulate blood pressure and heart rate.
Here we will share our favourite electrolytes for POTS that are available in Australia in 2026, so you can find one that is right for you!
Please note: check with your health care team (Cardiologist, GP and/or Dietitian) before increasing sodium! People with high blood pressure or on heart medications may not need additional sodium. For more information on why electrolytes can be helpful in POTS, check out our previous blog article on POTS & Hydration.
Sodium vs Salt
When discussing electrolytes for POTS, it's essential to distinguish between sodium and salt.
While "salt" generally refers to sodium chloride (that is, our table salt), sodium itself is a vital mineral (Na in the periodic table) that helps regulate blood pressure and fluid balance.
For POTS patients, increasing sodium intake can improve blood volume and pressure, reducing symptoms - and this is typically achieved through consuming more “salt".
The recommended daily sodium intake for POTS patients varies, but it can range from 2,000 to 10,000 mg sodium (2-5 tsp table salt) per day conservatively, depending on individual needs.
👉 Remember! ½ tsp table salt is roughly equivalent to 1000mg sodium.
What to Look for in an Electrolyte
Choosing the right electrolyte for POTS is critical for managing the condition. Here are key factors to consider:
Sodium content: We need sodium to help regulate our blood volume, which is key to managing POTS. To help you meet the 4,000-10,000mg daily sodium target for POTS, it’s best to choose electrolytes that contain at least 300mg sodium per serve.
Sodium - Potassium Ratio: Ideally we want electrolytes that contain 5 parts sodium to 1 part potassium. This is because too much potassium may potentially put unwanted strain on the kidneys. For example, if an electrolyte contains 500mg sodium, it should contain around 100mg potassium.
Sugar content: While some sugar can aid in absorption and hydration, high sugar content can often impact blood sugar levels. Opt for electrolytes that contain <5g sugar per serve.
Minimal colours and natural flavours (if you have MCAS!): Some products contain flavours which can be MCAS triggers (e.g. citrus, pineapple). If you know you are sensitive to these or synthetic flavours, colours or certain preservatives, make sure to avoid these. If you have aspergillus mould allergy, you may benefit from avoiding synthetic citric acid, so look out for this in the label.
Ease of Use: Consider the form (powder, tablet, drink) and convenience of the supplement. If you need to work on your fluid intake, a powder form may be better.
Added micronutrients: it’s not uncommon for some electrolytes to contain added vitamins and minerals, like B Vitamins, Vitamin C and Zinc. If you are having more than one or two serves of these products a day, it is worth checking in with your Dietitian or GP as you may need to limit your intake of these products or have additional blood tests (e.g. a B6 test to check for toxicity). For people with POTS, no added micronutrients is usually best!

So, what's the verdict?
At the end of the day there is no one-size-fits-all electrolyte for POTS. Depending on your needs, it's important to consider sodium, carbohydrates and cost when making your selection. '
Remember, electrolyte supplements aren't the only way to meet sodium requirements with POTS. So if you're finding they're not your cup of tea don't stress, there are lots of other great options including salting food and salt tablets.
If you're still not sure which electrolyte is right for you or if you are having trouble managing your POTS, book an appointment with the Savvy Dietetics team for a personalised plan.
