Prescribed For Life Ace K Sweetener, Acesulfame Potassium Powder, 200x Sweeter Than Sugar Zero Calorie, Kosher, Semi Natural, Granular Sweetener (12oz / 340g)

My go-to with this is to dissolve it in water, then mix the dilute AceK half and half with liquid sucralose and put it in a dropper bottle. This is an extremely strong sweetener, so doing it this way is helpful to give you the right amount of control over how much sweetness you add. Add more water to weaken it if you find you need to make finer adjustments for level of sweetness. It's the best sweetening with the least aftertaste I have yet discovered. Buying it in this form is also super cost effective; one bag of this lasts me at least six months when I prepare it this way, and I use it multiple times a day every day. The liquid sucralose is also very affordable. It's way cheaper and produces a lot less waste than buying packets of sweetener.

This is a very effective sweetener. However, the amount you need to sweeten a cup of tea or coffee is vanishingly small, and it is way too easy to use too much. It tastes terrible if you put too much in, and the aftertaste from too much can linger for an annoyingly long time, but if you get just the right concentration, it's a very good alternative to sugar. I guess that's why you see it listed as an ingredient in so many mainstream diet sodas.

This is good if Ace-k is what you need. If you’re shopping for something that tastes like sugar, you might find pure aspartame a better choice. I deducted one star for taste and another for country of origin (China). I’m not a fan of digesting manufactured foods from other countries. This is definitely concentrated and likely pure as stated. A small amount on the tip of a teaspoon is enough make your coffee as sweet as 4 sugar packets. It’s definitely more economical than packaged sweeteners, which have fillers and other sweeteners mixed in. That said, the pure Ace-k may be too bitter without cutting it with aspartame. I’ve been on a quest to find a viable sweetener that does not have a bitter aftertaste. I tried both name brand sweeteners, and the underlying substances where possible. The list includes Splenda, Equal, Nutrasweet, saccharin, Monk Fruit, Stevia, swerve, erythritol, aspartame and acesulfame potassium (“Ace-k”) Many of the name brands have fillers and flavors added to them. In the case of some retail packaged sweeteners, they contain a mixture of Ace-k, aspartame and dextrose. The closest I could get to real sugar was swerve and Equal. Swerve was very expensive and did numbers to my stomach. Equal was better but it still had a bitter aftertaste. Lesser than the others, but it was still there. I decided to try the two sweeteners in Equal separately. The Ace-k was very bitter and worse than Equal. The aspartame turned out to be almost identical to sugar with zero bitterness at all.

Just my opinion; but this stuff tastes awful. After one tiny sample, I threw the entire bag away.

I'm on a very low carb ketogenic diet. This sweetner is really strong and a little goes a long way. It is best to blend this with sucralose (ez-sweet.) as those two sweeteners happen to cancel out each other's aftertastes. In combination of these two sweeteners I'm able to enjoy hard apple cider that tastes just like sweet carby drinks such as angry orchard. The ideal ratio you want is 20% of ace-k contributing to sweetness, with 80% being ez-sweet. To sweeten a dry 12oz bottle of hard apple cider (such as ace joker dry) to have the sweetness of 25 grams of sugar (the amount in angry orchard), you'd want 25 milligrams of ace-k, and then 2-5 drops of the 2oz/800 servings of EZ-Sweet. Ace-K is 200x sweeter than sugar so 2.5mg = 5g of sugar, then the 2-5 drops of ez-sweet makes up for the rest of the sweetness. This ratio nullifies the aftertaste of both sweeteners. Don't use ace-k by itself unless you want a really bitter aftertaste. This product has totally changed my life!

So far I've only tried a little bit of this. As a starter, being in powdered/granular form it's a bit difficult to use, so I made a 10% by weight solution of it with water, similar to the 12.5% by weight sucralose sweetener I have. That is stored in a couple of cleaned out/repurposed "Mio" style squirt bottles. The first two negative reviews I've seen indicate that "they've seen it's used in diet sodas" without bothering to do further research. Ace-K is almost NEVER used on its own. It's used in combination with other sweeteners, and (based on an analysis of the ingredients of SodaStream's Dew Zero Sugar and a few research papers/studies) usually providing only 20-30% of the sweetness of the blend. For example, SodaStream's Dew ZS has 48 mg of caffeine per 12 ounce serving, and less Ace-K, with Ace-K + sucralose providing the equivalent of 46 grams of sugar. So Ace-K is providing at most 20 percent of the sweetness there. Adding a bit of this to a purely sucralose-sweetened drink definitely does seem to "round out" the taste of the drink, with a smoother taste than sucralose alone. Using this on its own will NOT provide you with good results. Unlike some other reviews that stated the conversion factor printed on the packaging was wrong, the conversion factors printed on the packaging I received (1/4 teaspoon Ace-K per cup of sugar, 200x) are consistent with published conversion factors for Ace-K. Of course, per my earlier comments, using this as a sole substitute is not a good idea. The commercial world universally uses this in blends with other high-potency sweeteners such as aspartame and sucralose. I'll update this review if I find any inconsistencies/negatives beyond that which is expected for a product that claims to be pure Ace-K.

I REALLY wanted to like this. After learning Coke Zero uses this to make the soda taste so close to the real thing with no sugar, I had to try it to help cut back on my sugar intake. Unfortunately, every way I tried it just added too much bitter after taste, the reason I generally shy away from sugar substitutes in the first place. I've tried mixing it with sucrose as others suggested to help alleviate the aftertaste, or at least lessen it, but it's still way too much for me. The positives are, if you can tolerate the aftertaste it is extremely sweet and very little goes a long long way.

Taste like potassium bitter but also high Octane sweetener with a nasty aftertaste
