I use Elete(TM) water when riding because I sweat a lot, and if I don't drink electrolytes I get horrendous headaches, and cramps for days afterwards.
Today I wondered if I would be better off buying individual bulk bags of Magnesium Chloride and Potatassium Chloride etc., and mixing up my own to save money.
Anyone else ever tried it? Elete is just sodium, potassium, magnesium and calcium chlorides in solution, so it can't be that hard to do.

That's a lovely idea, but as I have poor digestion, I find I have to get my salts in solution so they're absorbed in the stomach. Hence relying heavily on electrolyte drinks instead of food.

Do you chew when you eat?
Probably cheaper to buy electrolyte powder from My Protein.

Hydrate properly and frequently and you won't lose salts.

Entirely missing the point there. Chewing does not release cations into solution.

Chloride and maybe sulphate are probably the best bets.

That's what I do - hence currently using elete. But water alone doesn't replace salts, and it doesn't prevent you losing salts to sweat.
Interesting
I suffer crohns/colitis so never use water as it doesn’t hydrate me or put electrolytes back
I use Dioralyte to rehydrate sometimes which works well
Think a solution called st marks solution is meant to be good for hydrating

The point is that if you keep your water levels up, you don't lose salts, ie you only need plain water.
Your body automatically maintains your salt levels (isotonic), and it's only if your internal water level drops that it will excrete salt which has thus become excess, ie trying to maintain the isotonic level.

This isn’t exactly accurate, although there is some truth to it.
Unless you have certain medical conditions, sweat will always contain some amount of sodium and other salts, along with a bunch of other chemicals. Studies have shown that intensity of exercise - independent of sweat volume - also has an impact on the amount of salts in your sweat.
To OP’s question - I’ve often wondered same, but find that Nuun tablets aren’t too expensive, and the slight expense overcomes my laziness at trying a DIY solution.
Pint of lager.
I'd be concerned about getting chemicals from a source that isn't food-grade. Could easily be contaminated with impurities you don't want.
I'd suggest reading a bit more about the constituents of sweat, and about electrolytes and the way your body has a few million years of evolution which enable it to deal with a bit of exercise with swallowing special drinks...

Don't think so Matey boy. Pretty sure increasing the surface area increases the speed stuff dissolves, not to mention the action of saliva
Interesting radio show with an acknowledged (perhaps even on here) expert on salt. Doesn't get into exercise but states that you don't need anything like as much salt as most say.
During my degree we did a comparison between branded isotonic drinks and a homemade recipe using mass spectrometry. There was effectively no difference.
The recipe was:
100ml squash (preferably not no-added sugar)
400ml water
1/8 teaspoon salt
Nice, easy and cheap.
@malv173 - did you use sea salt or table salt? I had read that you needed to use sea salt as it isn't 'pure' like table salt and naturally contains the other minerals, but was always a bit dubious, so I'd be really interested to hear what proper analysis showed up.

Yup, it's amazing how all those folk who live in tropical areas get by without electrolyte drinks.
It's almost as if humans evolved in the absence of all those advertorial promoted special waters... 🙂

Want to give that a try.
What is the above diluted to mate? 1 Litre?
Also, I'm not doing carbs these days so will use no added sugar juice. Won't get the energy rush but should still dehydrate ok?
Thanks for info!
What is the above diluted to mate? 1 Litre?
500ml 😉 and yes you’ll dehydrate just fine without sugars.
@poopscoop what Drac said. I tend to make 2l, so use 400ml squash, 1.6l water and half a teaspoon salt.
@superjohn71 I just use table salt. That's what we used in the experiment. Seems to work ok for me.
Thanks guys.
Emailing that "recipe" to myself to try out.
Oh, is "low salt" ok, or should I get some full fat salt? Lol

All of the above, preferably with an icecream too. And maybe a bacon sandwich.

Fried salt is best. Preferably served on potatoes.
Or try what works in 35ºC+ for an all day uphill climb.
Plain water with a dash of lemon juice to make it palatable when warm.
It's ages since I read I to it, but isn't the salt level (as per the DIY version) about absorption rather than replacement of salt in the body?
Absorbtion of water may be affected by the presence of electrolytes, but not to a significant amount, although Elete water may well claim differently...
The fundamental lesson is that sweat removes far more water than electrolytes, so sweating makes your body fluids 'saltier'. The best way of correcting that is to drink water, and only to drink to thirst, not some made up regime.
As referred to above, homeostasis is a feature of human physiology; your body is way better than you at making sure it's in tip-top shape, and has had millions of years to get it right.

IIRC Crikey has it but it’s over 20 odd years since I did it and yes Paton is right too just water is enough especially with a snack.
Cynic al - there are several issues that get muddled when folk talk about Isotonic drinks. Yes the osmolarity of it affects the way it is absorbed. Yes you need a little bit of salt to replace losses but nothing like as much as you need to make fluid isotonic. . 9 grammes of salt in a litre of water to make it isotonic. IIRC - far too much salt to be good for your health! This is why most sports drinks are stuffed full of sugar to make them isotonic without using all that salt. 40 grammes of sugar and 2 of salt in a litre is isotonic ( again iirc)
Your body is incredibly good at regulating fluid and salt levels without help.
Crikey - good to see you back on these threads 😉 I have missed your contributions 🙂 ( IIRC this is your area of expertise? )

My body? The OP's body? Everyone's? I'd have thought someone with your level of medical expertise TJ would apprecaite that not everyone's body is the same and some people's bodies don't even work perfectly.
I don't drink electrolytes normally, but there's a point after long hot rides where I find I cannot slake my thirst no matter how much water I drink (and even if I pee a lot) so I have something with a little extra salt in it. This seems to help.
Arguing over theory is all well and good but we are all individuals and if the OP has experimented on himself and found certain not unreasonable effects then who are we to argue?
Hi TJ!
It's not my special area of interest, but I have spent time looking into it (and many, many hours writing blood gas results down...)
Molgrips, we are talking about basic human physiology; yes, people are different, but not at a cellular level.
There are a number of misconceptions surrounding the issue, not helped by a lucrative global industry aimed at selling stuff. An open minded read of the links above is well worth half an hour or so.
Goodness me, there are a lot of experts on my particular physiology, aren't there?
We love you from the inside too 😉
16stone pig
the point is that a lot of what is written about fluid and electolyte replacement is confused and poor science.
On a cellular/ gross physiological level then yes we are all the same under the skin!
If you drank 3 litres of electrolytes at isotonic levels then thats 27 grammes of salt - or your full weekly requirement and more. Or if the isotonic is produced by sugar 150 gammes of sugar or 600 calaries of sugar again a huge amount over your required amount in a healthy diet.
I used to get bad headaches after a ride cured by half a tablespoon of salt in an orange drink. It does work. Never needed it during a ride although maybe I would if I rode all day.

What? Are you telling us you're not human? 🙂
Half a tablespoon? do you mean half a teaspoon cos half a tablespoon is way too much salt
TJ, I have explained that I have particular problems with hydration, and how I deal with the symptoms. It's no good chucking the theory at me and telling me I'm wrong about my own experience of 15 years of sweaty cycling.
@16stonepig have seen a GP to see why this may be the case your digestion is slow, you’ve asked for help but provided no medical history. Fluids and salts are absorbed pretty quickly through smooth muscle so I’m intrigued.
My digestion was crap due to stomach inflammation but meds sorted that a few years ago, I never really had problems absorbing water though.

Heard about this company on a Trainer Road podcast. They do a sweat test.
People do sweat differently, here is a bit of literature that refers to the fact (just did a quick Google Scholar search).
I am confused about this "cellular level". That is where it all happens, if there are any differences between individuals' physiologies that happens at a cellular level.
The point both crikey and I was making is that the consumption of isotonic drinks is a muddle of misconceptions and bad science poorly applied and advertising masquerading as science- and that the body regulates its fluid and salt content on a cellular level and we all do it the same way unless you have weird metobolic diseases
Erm, I was never asking for medical advice, but as @molgrips said further up there ^, we are talking about individuals, not an ideal spherical human in a vacuum.
But to clarify - I sweat constantly, even when sitting still. I have chronic digestive issues (and the only answer I can get out of my GP is to maybe eat more cabbage, or less cabbage, I dunno, here's a leaflet).
I suffer from Chronic Fatigue Syndrome, have very aggressive allergies, asthma, get muscle cramps and tics even without exercising.
You'd be forgiven for being amazed I ever even ride a bike, but I do. And when I do, I rely heavily on electrolyte solutions to aid my endurance. If I don't use them, I will have a crippling headache for hours after a ride, regardless of how much water I drink. Oddly, they even aid my concentration and reflexes, allowing me to ride much more confidently.
So, we're all individuals, and the medical paperwork does not negate the fact that I have done the following very scientific experiment:
1: OBSERVE that I dehydrate and suffer cramps when cycling.
2: HYPOTHESISE that a lack of electrolytes causes this.
3: EXPERIMENT by adding an electrolyte supplement to my drinking water and checking the results.
4: REPEAT the above many many many times.
RIGHT - now that's out of the way - is there any harm in me buying some food grade Mg,K,Ca chlorides and mixing up a concentrated solution myself in ratios similar to my current supplement? It could potentially save me money and the hassle of ordering a new bottle every few months.
NO problem at all with making up your own. None. Its just a mix of salts of various kinds sometimes with sugar.
Be careful of ending up with too much salt or sugar consumption overall - they are not good for you. As above 3l of isotonic solution of salts is more than your entire weekly desirable amount of slats and this can lead to high blood pressure and cardiac issues
Do you think yo might have some sort of malabsorbtion syndrome?
Do you think yo might have some sort of malabsorbtion syndrome?
That is an entirely other discussion, which this forum is not the best place for, but thanks for the concern.
I am actually now thinking about experimenting with a solution of everything except sodium, or at least reduced sodium, since sodium is bloody everywhere.
Watch out for too much magnesium and calcium as well. I seem to remember that can cause cardiac issues as well but that dug right out from the back of my memory.
You should be able to find good data on this on the net - look for maximum amounts of the electrolytes
@tjagain - we may all do it in the same way, but it is chemistry not computing, so different people may do it to different extents. Which is not to rule out the possibility that genetic differences mean that some individuals do it a bit differently as well.
