Pros: Nothing works better
Cons: Taste for some people, especially warm. Best served cold.
I have used Gookinaid doing first aid on many people. It is an incredibly effective electrolyte replacement. Mix the powder with water and drink. Chris was cement sidewalk grey from 24 hours of boozing and no water at Burning Man, in the desert. An hour later, after drinking most of a gallon of Gookinaid he was back to his usual sickly pale self. It works wonders on altitude sickness as I found out one year at a Rainbow Gathering at 10,000 feet. I have been using this as an IV in a can since 1998. Do not inject Gookinaid. It is for drinking purposes only.
I do feel the product is more effective made slightly weaker. I suggest 1 heaping scoop for a 32 oz (1 liter or 1 quart) mug of water, using the red scoop that is included. If you dislike the taste, you will probably find this weaker strength better tasting. At this strength it is pretty taste free. It is not sickly sweet like Gatorade even at full strength. As far as flavor goes, each person I provide it seems to have their own preference. I personally prefer the grapefruit and lemon because they have the least taste. The orange and citrus definitely have a bit more flavor.
I buy 18 cans every 2 months or so, selling most of it to friends at cost, cheaper than REI (local seller) would sell to them for. The rest my wife and I drink.
Flu, cold, vomiting, dehydration, diarrhea, feeling lousy, hangover, chronic illness, altitude sickness, sweating a bunch, muscle soreness, heatstroke, dehydration Gookinaid works wonders for.
I have several friends including my wife with chronic illnesses and Gookinaid has vastly improved their quality of life. It didn't fix them, but their overall suffering is less. Less bad days is huge, and the bad days are less bad. My friend Curtis, a roofer, won't do roofing without his 'superwater', his name for Gookinaid.
One chronic health condition I would seriously ask a doctor for advice before using Gookinaid would be anyone with dialysis because of the potassium that dialysis patients need to avoid. Avoid the grapefruit flavor if taking auto immune disease drugs, as grapefruit tends to interact badly with them. The same goes for anyone taking anti rejection drugs for transplants.
Gatorade is poison. Way too much sugar and a lousy balance of electrolytes. It really is not much better than a can of soda, and was designed mainly to sell well, not work well. If you absolutely have to use Gatorade for dehydration water it way down. Gatorade is also very hard on the stomache. Gookinaid calms the stomache. Pedialyte is far too expensive for anyone needing it regularly and Gookinaid is a better product. With Pedialyte you are paying mostly for water and packaging. Gookinaid is a dry powder you mix with water.
IVs for first aid at large scale multi day events with thousands of people are incredibly expensive. IVs cost around around $200 each. 1 kilo can diluted to the strenth I normally use is equal to 10 gallons. 10 gallons of IVs cost around $8000, way beyond the entire budget of many events. Never mind the issues of disposing of needles, and having to transport 10 gallons worth of IVs. If they are conscious, Gookinaid mixed in water is a much cheaper choice. If they are incapable of drinking then you cannot use Gookinaid, and need IV's instead.
When we adopted 2 cats from a shelter, they gave all of our cats a major respiratory infection. Gookinaid helped our 8 cats tons. We had to use lemon or grapefruit, they wouldn't drink the orange because of the color even when dilute. Michell, a rat breeder, used it recently when all of her rats were sick. She felt she lost far fewer rats thanks to the Gookinaid.
My one complaint with the product is occasional busted cans, damaged during shipping. Even 1 leaking can in a box of 18 cans leaves a trail of white powder everywhere, even with the shipping box still sealed. However they are very good about replacing them.
I can't find anything better at any price. I need things that actually work and Gookinaid has done so consistently.
