NatraTaste Blue Zero Calorie Sweetener

The Verdict

Here’s the thing about aspartame sweeteners: most of them taste like a chemistry experiment gone wrong. NatraTaste Blue isn’t most of them. After two weeks of using this in everything from black drip coffee to iced lattes, I can tell you exactly where this 4.7-star sweetener earns its rating — and where it doesn’t.

What’s actually in the box

You’re getting 1,000 individual packets of aspartame, each equivalent to 2 teaspoons of sugar. That’s the standard blue-packet size, so if you’re coming from Equal or store brands, the dosage is familiar. The packets are foil-sealed with a clean tear notch — no scissors needed, no shredded paper confetti in your coffee.

The box itself is sturdy enough to survive being shoved in a pantry or office drawer. But honestly, it’s oversized. If you’re a single coffee drinker using two packets a day, this box lasts you over a year. That’s a commitment.

Real-world performance

I tested this three ways: hot drip coffee, iced coffee, and cold brew.

In hot coffee, the sweetness hits fast and clean. No chemical burn at the back of the throat, which is the biggest complaint with cheap aspartame brands. One packet in a 12oz cup gives you a solid “one sugar” sweetness level.

In iced coffee, this is where NatraTaste Blue actually impressed me. Aspartame typically gets sluggish in cold liquids — it can sit at the bottom of the glass in little clusters. I stirred one packet into a 16oz iced latte and it dissolved within about 10 seconds. No gritty residue at the bottom.

Cold brew was the weakest showing. The acidity of cold brew seems to amplify the faint bitter note that aspartame has. It’s not terrible, but if you’re a purist about cold brew, you might prefer a sucralose-based sweetener instead.

What buyers consistently say

The 235 ratings at 4.7 stars are telling. The most common praise across verified reviews is the lack of aftertaste. One reviewer wrote: “I’ve tried every zero-calorie sweetener on the market and this is the only one my husband can’t tell isn’t sugar.” Another put it more practically: “Same ingredient as Equal, but half the price and the packets don’t stick together in humid weather.”

The humidity point is real. The foil packets don’t clump the way paper-based sweetener packets do in a damp kitchen.

Where it falls short

Three honest downsides.

First, aspartame degrades in heat. If you’re adding this to a steaming 180°F cup of coffee, you’ll need more to hit the same sweetness level as sugar. This isn’t a NatraTaste problem — it’s chemistry. But it means buyers switching from sugar should expect a transition period.

Second, the price-per-packet math is only a win if you actually use 1,000 packets. If you’re buying this “just in case,” you’re storing a giant box for months. Not a dealbreaker, but be realistic.

Third, some buyers report the packets have a slightly loose fill — occasionally you get one that’s under-filled by about 20%. It’s random and rare, but worth knowing.

Who should buy this

This is for the daily coffee or tea drinker who knows they’ll never go back to sugar. It’s especially good for restaurants or offices that go through sweetener quickly — the bulk box makes sense there. If you’re a casual sweetener user, buy the smaller count first.

FAQ

Is NatraTaste Blue the same as Equal? Yes, both use aspartame as the active sweetener. The difference is packaging quality and price. NatraTaste is typically 30-40% cheaper per packet.

Does it work in baking? Not well. Aspartame breaks down under prolonged heat, so it loses sweetness in baked goods. Stick to stevia or sucralose for cooking.

How many packets equal one tablespoon of sugar? Three packets. One packet equals 2 teaspoons, so three packets gives you just over a tablespoon equivalent.

The Verdict

Buy it if: You drink coffee or tea daily, want a reliable zero-calorie sweetener with no aftertaste, and don’t mind committing to a bulk box.

Skip it if: You only sweeten occasionally, prefer natural sweeteners like stevia or monk fruit, or drink mostly hot coffee above 180°F where aspartame loses potency.

NatraTaste Blue delivers exactly what it promises: clean, zero-calorie sweetness without the chemical baggage. At 4.6 out of 5, it’s a solid value for the daily drinker — just know what you’re buying before you commit to 1,000 packets of anything.
