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.

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.

Phenomenal product!!!!
4 days into a 5 day fast and this product is carrying me! Makes water slightly salty but that’s unavoidable. Very impressed!

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.

Great Keto Fasting Electrolytes
I am keto and its hard to get a balance of the electrolytes with some of my pre-existing issues. These do the trick. No they don't taste good but if you are a seasoned fasting warrior like myself this is exactly what you want, no flavoring and no sweetner, just sea water. Took away my headaches, brain fog and fatigue within the first few glasses. You get used to the taste if you dilute it properly. Squeeze of lemon or apple cider vinegar helps too.

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.

Not for a clean fast
Watch out. This is not ok for a clean fast. Citric Acid is the culprit. Don't tell me "it's such a small amount so don't worry" WRONG!!

Analyze the actual ingredients,
I was really surprised about the amount of sodium bicarbonate in this.. just felt like I was suckered into buying a box of arm n hammer Baking soda repurposed. Follow with a shot of apple cider vinegar and relive your 3rd grade Volcano presentation.
