Electrolyte Drinks for POTS: How to Choose One (and a DIY Recipe)

The one number that actually matters

If you have POTS, you have been told to drink electrolytes roughly a thousand times. What almost nobody tells you is which number on the label to look at. It is not the flavor, the brand, the “advanced hydration” badge, or the long list of trace minerals. It is a single figure: milligrams of sodium per serving.

Sodium is the electrolyte that holds water inside your blood vessels. In POTS, a large share of people run with low blood volume, so when you stand up there is simply less fluid for your heart to work with, your heart rate spikes to compensate, and you feel it. Pulling more sodium (and the water it carries) into circulation is the whole rationale behind the “salt and fluids” advice, and it is covered in more depth in our pieces on the science of salt and fluids and low blood volume in POTS.

Here is the problem with most electrolyte drinks: they were designed for healthy athletes replacing modest sweat losses, not for someone trying to expand blood volume. So they are diluted for taste. A standard sports drink gives you about as much sodium as a light snack, when many POTS protocols are aiming far higher across the day. You can drink it all afternoon and barely move the needle, then conclude electrolytes “don’t work for you.” They do. The dose was just too small.

How much sodium are we talking about?

This is where you need a clinician, not an article. Sodium targets for POTS are genuinely individual, and published management guidance tends to land in the range of several grams of extra sodium per day on top of a normal diet, paired with generous fluids (often a couple of liters or more). Some people do well toward the lower end; some protocols go higher. Our POTS treatment overview walks through where salt-loading fits alongside compression and exercise.

The practical point for choosing a drink: once you have a daily sodium target, you can work backward to how many servings of which product get you there without drowning yourself in fluid or sugar. A target met with two high-sodium servings is easier on your stomach than the same target spread across eight weak ones.

Comparing the common options

Below are rough sodium figures for popular choices. Treat them as ballpark: manufacturers reformulate, and serving sizes differ, so the label in your hand always wins over any table on the internet.

A few things stand out. Coconut water gets marketed as “nature’s sports drink,” but for POTS it is almost backward: lots of potassium, barely any sodium. Standard Gatorade and Powerade are fine as something pleasant to sip, but you would need roughly six to seven cups to match one high-sodium stick, which is a lot of sugar and fluid for the sodium you get. And the higher-sodium products are not magic, they are just concentrated. You can reproduce any of them at home.

Why a little sugar actually helps

It seems like plain salt water should hydrate you best, but it does not. Your small intestine absorbs sodium and glucose together, through the same molecular transporter (SGLT1), and water follows that movement across the gut wall by osmosis. Add a little glucose and you switch on a pump that drags sodium and water in faster than salt alone. This is the entire principle behind oral rehydration solutions, the formula that is a frontline treatment for dehydration worldwide.

You do not need much. The classic rehydration ratio is modest, and a very sugary drink is not better. For POTS, a small splash of fruit juice or a half teaspoon of sugar in a liter is plenty to get the benefit without a sugar spike, which matters if you also deal with reactive blood-sugar swings.

The DIY recipe

Once you understand the parts, you can make a liter of effective electrolyte drink for a few cents, and dial the sodium exactly where your clinician wants it.

Mix, taste, and adjust. If it tastes like weak seawater you have the dose about right; most people are surprised how little salt it takes to be noticeable. Make a jug in the morning and sip it across the day rather than downing it all at once, which both absorbs better and is gentler on your stomach.

When to drink it

Timing is where an electrolyte drink earns its place in a pacing routine. A few patterns people find useful, all worth personalizing:

• First thing in the morning. POTS symptoms are often worst on waking, partly because you lose fluid overnight. A glass of your mix before you stand up can take the edge off.
• Before upright activity. A fast intake of fluid can briefly raise blood pressure and blunt the heart-rate jump on standing, which is the idea behind the water bolus response.
• Across the day, not all at once. Steady sipping keeps blood volume topped up better than one large drink your kidneys quickly dump.
• Around heat, showers and exercise, when you lose more sodium and fluid.

What an electrolyte drink cannot do is fix everything. If salt and fluids alone are not enough, that is common and expected, and it is why POTS care usually layers compression, a gradual exercise ramp, and sometimes medication on top. Hydration is the foundation, not the whole house.

Tracking whether it actually helps

The honest way to know if an electrolyte routine is working is not how you feel in the ten minutes after a drink, it is what your trend does over weeks. Standing heart rate, symptom load and morning HRV all respond slowly to better blood volume, and day-to-day noise can easily hide a real improvement if you are only going on memory.

Frequently asked questions

What is the best electrolyte drink for POTS? The one that reliably hits your sodium target and that you will actually keep drinking. Read the label for milligrams of sodium per serving first; taste and cost second.

Is LMNT good for POTS? Its high sodium (~1000 mg per stick) and lack of sugar make it a convenient way to salt-load, which is why it is popular in the community. The same sodium is achievable with a homemade mix if cost is a factor. Whether that much sodium is right for you is a clinician question.

Do I need the sugar? A little helps you absorb the sodium and water faster through sodium-glucose cotransport. You do not need a lot, and if you are avoiding sugar you can use a plain salt-and-water mix and simply drink a bit more of it.

Can electrolyte drinks replace my medication? No. Salt and fluids are a foundation, but many people need compression, graded exercise or medication as well. Never change a prescribed treatment based on an article.

These are educational field notes, not medical advice. POTS and dysautonomia overlap with conditions where extra salt can be harmful, and individual needs vary widely. Set your sodium and fluid targets with a clinician who knows your history, and discuss any changes with them first.
