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!

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.

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.

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.

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.

Confused
I’m confused. Everyone keeps talking about how this is suppose to be super salty but I am not tasting an ounce of saltiness? Did I get a bad bag?

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.
