It's pretty good, and has more potassium relative to sodium than most other similar products.
It has quite the array of minerals and trace elements, but the largest in quantity contained in the package is potassium, which is good. Some have stated that it is more salty than lmnt, which is impossible according to the laws of thermodynamics and basic physics. If you can do elementary math and ratios, you will see that it contains far more potassium relative to sodium, while lmnt has far more sodium relative to potassium. You don't even have to buy the product to find this out, the nutrition labels are available in the Amazon listings. Lmnt is not a good product for me because it contains too much salt relative to the rest of the minerals, and I get enough salt in my diet from food. This product called fasting electrolytes, I take it even though I'm not fasting. The extra potassium and magnesium help keep me from developing muscle cramps especially at night. The taste is not particularly good, it's just minerals and no sweeteners. But I add in small amounts to my lemon water throughout the day, or a little bit in my coffee. I'm pleased with the product, and will continue to order.

Amazing!
The price is fantastic per serving, way better than the only other brand of non flavored non sweetened electrolyte power on the market. I've been using this for this last year for everything from hiking/backpacking to keeping the throat lubricated singing on my parish choir. I actually quite enjoy the salty taste personally but I'll admit I'm likely an outlier there. Also not making medical claims here so grain of salt (har har), but I feel like this stuff helps me regulate my blood sugar better, especially when doing longer fasting (I'm not diabetic but mildly hypoglycemic). I'd give it a 10/5 if I could it's honestly that good and the price can't be beat.

Salty because it's salt. Put it in something sweet!
So OF COURSE this stuff is gonna be extremely salty. Anyone who is surprised by that just did not know what they were ordering. I put this in my daily lunch smoothie and it tastes amazing. My smoothie is as follows: 1 scoop sixstar protein powder 1 cup frozen fruit (mixed berries if using chocolate powder, tropical blend if using vanilla) 3 handfuls of spinach 1/2 cup dry oats 2 tbs ground flax 1/2 cup vanilla oikos triple 0 3/4 cup coconut water 1 4cc scoop of electrolyte powder 14 ice cubes This results in a 32oz smoothie and the umami/sweet flavor combo is addictive. Literally the highlight of my day!

Found the right electrolytes product
I haven't yet recieved this product, so I cannot review the products results or details from experience as of yet. This review is mostly for those who are looking for an effective, naturally formed sources of electrolytes, which in this case, is formulated for fasting. Its not the only way to use it, though it does make this product unique for those purposes. Along side noting this product with this brand specifically, is what I look for in the use of health supplements, in that it is infact naturally formed and sourced, along with the near proper dosages for each essential electrolyte which makes it overall a better choice over others. From what I see in searching with electrolytes supplements, is that it may tend to have different amounts of each which can increase and decrease ingredients, and there tends to be one that isnt the best choice as far as actually absorbing it in the body. The simple fact is, is that the more expense it takes to get one ingredient, it normally decreases the total amount in the product to reduce cost in producing, all the while it may increase the least needed ones to try and even out the scales. This particular product doesnt have that issue, and their will always be deabtes on what or how important something really is, and the dosages/timing etc. Its a plain requirement when using health supplements, to choose specific ingredients, amounts, and overall cost, and as far as the effectiveness goes, Ill add another review to speak on that subject. For now, for those who are looking for a good product/brand for electrolytes, this is the best one Ive come across so far. Good luck with your purchase.

Gross but effective
It’s yucky, no way around it. It’s not even the flavor really. It somehow manages to make water feel thick. However the balance of magnesium, potassium, and sodium is king. If you’re on a budget like me and don’t want to buy a bunch of supplements while fasting, go here. Suck it up and suck it down. Use lemons.

Perfect for fasting. Cheap, convenient, easy. Resealable with two scoops.
I did some fasting this week (just to see what it was like, yes total tourist) and studied up ahead of time to see how to do it safely. One thing was 'take electrolytes with water, your body needs those' so I jumped on here and started looking. You need no sugar no filler (no gatorade!) because any calories will mess up the fast. You can buy a lot of packet products, but those are 10x the cost per gram. This comes in a resealable bag, instructions on the back for your schedule, and two plastic scoops to make it easy! So first day is just one small scoop in a liter of water, couldn't be easier. Just make sure you completely seal the bag up, as, like other salts, it'll probably clump if left open by absorbing moisture from the air. You can always just crush the lumps again, but sealing is a penny of prevention.

Worth the price
This stuff is like magic! It just tastes like powdered salt, which is fine to me, but it has helped tremendously with my cramps and headaches! It works almost instantly! Whether you're fasting or simply want electrolytes without sugar or artificial sweeteners, I highly recommend this! At first I thought it to be expensive, but considering how little you can take for it to work, I believe it to be priced right. It comes with two scooters, a tiny one and a bigger one. I only use the tint one. This bag should last me quite a while. Longer than a month.

Spoiler: this bag of salts tastes salty
The product is exactly what it says it is. Anyone complaining about taste fundamentally does not understand what they were buying and probably should not be allowed to shop without supervision. The package comes with two different sized scoops that make measuring very easy, along with clear instructions on how to use the product.

best value real electrolytes
Best value real electrolytes that I have found and used. So much expensive garbage out there with extremely small amounts of potassium and sodium, I am glad this exists and will continue buying for years to come.

IT WORKS
This stuff tastes BAD, let it be said, if you are expecting some sugary / glucose / aspartame / stevia slop, you won't find that here, this stuff tastes like sea water or maybe slightly worse. However if you are searching around for a CLEAN effective electrolyte that isn't filled with random chemicals this is exactly what you want, it is a pure combination of different salts that does exactly what you want.

Speedy delivery
WE placed our order on Monday and received delivery on Tuesday. We love these electrolytes, best on the market. Expensive but does not contain sugar or colors and flavours. Taste takes some getting used to but when you can handle it you'll love it.
