Are Electrolyte Supplements Worth It?
When to Take Electrolytes: A Guide to Hydration. Learn about electrolytes and when to supplement them. Find tips for staying hydrated during exercise and the potential risks of oversupplementation.
When To Take Electrolytes (And When We Shouldn’t!)
Any sports nutrition outlet will sell electrolyte supplements. Sometimes in the form of sports drinks that claim to be more hydrating than water, or tablets that can be dissolved in water to make the same. How do they work, and should we be drinking them?
What are electrolytes?
They’re called “electrolytes” because they are ionized particles (so, they have a positive or negative electrical charge, depending on which kind of ion they are) that are usually combined in the form of salts.
The “first halves” of the salts include:
- Sodium
- Potassium
- Calcium
- Magnesium
The “second halves” of the salts include:
- Chloride
- Phosphate
- Bicarbonate
- Nitrate
It doesn’t matter too much which way they’re combined, provided we get what we need. Specifically, the body needs them in a careful balance. Too much or too little, and bad things will start happening to us.
If we live in a temperate climate with a moderate lifestyle and a balanced diet, and have healthy working kidneys, usually our kidneys will keep them all in balance.
Why might we need to supplement?
Firstly, of course, you might have a dietary deficiency. Magnesium deficiency in particular is very common in North America, as people simply do not eat as much greenery as they ideally would.
But, also, you might sweat out your electrolytes, in which case, you will need to replace them.
In particular, endurance training and High Intensity Interval Training are likely to prompt this.
However… Are you in a rush? Because if not, you might just want to recover more slowly:
❝Vigorous exercise and warm/hot temperatures induce sweat production, which loses both water and electrolytes. Both water and sodium need to be replaced to re-establish “normal” total body water (euhydration).
This replacement can be by normal eating and drinking practices if there is no urgency for recovery.
But if rapid recovery (<24 h) is desired or severe hypohydration (>5% body mass) is encountered, aggressive drinking of fluids and consuming electrolytes should be encouraged to facilitate recovery❞

Should we just supplement anyway, as a “catch-all” to be sure?
Probably not. In particular, it is easy to get too much sodium in one’s diet, let alone by supplementation.And, oversupplementation of calcium is very common, and causes its own health problems. See:
To look directly to the science on this one, we see a general consensus amongst research reviews: “this is complicated and can go either way depending on what else people are doing”:
- Trace minerals intake: risks and benefits for cardiovascular health
- Electrolyte minerals intake and cardiovascular health
Well, that’s not helpful. Any clearer pointers?
Yes! Researchers Latzka and Mountain put together a very practical list of tips. Rather, they didn’t put it as a list, but the following bullet points are information extracted directly from their abstract, though we’ve also linked the full article below:
- It is recommended that individuals begin exercise when adequately hydrated.
- This can be facilitated by drinking 400 mL to 600 mL of fluid 2 hours before beginning exercise and drinking sufficient fluid during exercise to prevent dehydration from exceeding 2% body weight.
- A practical recommendation is to drink small amounts of fluid (150-300 mL) every 15 to 20 minutes of exercise, varying the volume depending on sweating rate.
- During exercise lasting less than 90 minutes, water alone is sufficient for fluid replacement
- During prolonged exercise lasting longer than 90 minutes, commercially available carbohydrate electrolyte beverages should be considered to provide an exogenous carbohydrate source to sustain carbohydrate oxidation and endurance performance.
- Electrolyte supplementation is generally not necessary because dietary intake is adequate to offset electrolytes lost in sweat and urine; however, during initial days of hot-weather training or when meals are not calorically adequate, supplemental salt intake may be indicated to sustain sodium balance.

Bonus tip:
We’ve talked before about the specific age-related benefits of creatine supplementation, but if you’re doing endurance training or HIIT, you might also want to consider a creatine-electrolyte combination sports drink (even if you make it yourself):
Where can I get electrolyte supplements?
They’re easy to find in any sports nutrition store, or you can buy them online; here’s an example product on Amazon for your convenience 🙂
You can also opt for natural and/or homemade electrolyte drinks:

Stop Cancer 20 Years Ago
Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.
Get Abreast And Keep Abreast
This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.
What does she want us to know?
Start now
If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.
What this means for those of us without breast cancer (or a history therof) is: start now
Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.
Start what, you ask? Taking away its roots. And how?
Inflammation as the root of cancer
To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.
Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:
“and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”
So, fight inflammation now, and have a reduced risk of a lot of other woes later.
See: How to Prevent (or Reduce) Inflammation
Don’t settle for “normal”
People are told, correctly but not always helpfully, such things as:
- It’s normal to have less energy at your age
- It’s normal to have a weaker immune system at your age
- It’s normal to be at a higher risk of diabetes, heart disease, etc
…and many more. And these things are true! But that doesn’t mean we have to settle for them.
We can be all the way over on the healthy end of the distribution curve. We can do that!
(so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)
If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.
So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:
See: Focusing On Health In Our Sixties
Fast to live
Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.
This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.
See: Intermittent Fasting: We Sort The Science From The Hype
While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.
It’s never too late
All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”
The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.
Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.
Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:
- Knowing stuff
- Doing stuff
So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.
