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!

This is FOOD, and solves multiple nutritional needs.
Could not be happier. Useful as a clean, simple and complete electrolyte mix, and as a substitute for table salt. The powder is superfine and goes in anything. We even used it for the pinch of salt in OATMEAL, and it was a healthier salt substitute that made the meal more satisfying. We're using it not only for electrolyte balance but also to clarify when hunger is hunger (vs nutrient craving), and as a food salt substitute (in moderation). One test we use for electrolyte mixes is to pour some one a plate, lick your finger, and dab some on a damp finger to taste it as-is. Does your body say it is food? YES, THIS IS FOOD, and it is GOOD. It addresses a spectrum of cravings. The packaging bag is thick and strong, well-sealed so don't worry anymore about those 2024 reviews about packaging defects. Those are often a shipment/handling issue but the bag is now so sturdy I think it's a nonissue.

BEST EVER ELECTROLYTE!!!!
I HAD A VERY PAINFUL SCIATICA AND WITHIN A FEW MINUTES OF TAKING A SCOOP OF THIS PRODUCT THE PAIN HAD COMPLETELY GONE, I MEAN GONE GONE GONE. WISH I'D STARTED TAKING THIS SOONER. AND, CONTRARY TO OTHER REVIEWS, I FIND THE TASTE OF THIS ELECTROLYTE FRESH AND CLEAN. GRATEFUL THAT THERE IS NO SUGAR OR STEVIA (WHICH I CAN'T STAND THE TASTE OF). BEST ELECTROLYTE I'VE EVER, EVER TRIED.

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.

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.

Great For Fasting
Amazing drink; I could feel the difference once I drank it. It helped me survive my first 84 hour fast. Thank you for this great product.

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.

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.

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.
