The NutriBullet Rx is a bullet blender that comes with three differently-sized jars. The main jar has a pouring spout and a two-part lid, and you can use it to heat ingredients. It's well-built and makes great smoothies as well as okay almond butter, although it tends to warm up the ingredients even when you don't want it to. On the plus side, unlike most NutriBullet blenders, it produces snow-like crushed ice. It's also very easy to clean by hand, and the jars and lids are top-rack dishwasher-safe. 

Our Verdict

6.7 Multi-Purpose

The NutriBullet Rx is okay for multi-purpose use. It's well-built and offers more versatility than most bullet-style blenders since it has a mode for making soups and sauces by heating cool ingredients. It makes snow-like crushed ice and great smoothies in its main jar. It also produces alright smoothies in its 40-ounce additional jar and okay almond butter, but unfortunately, it warms up the ingredients slightly. It's very easy to clean by hand, even when working with sticky ingredients, but the blade assembly isn't dishwasher-safe.

Pros
  • Easy to clean by hand.
  • Snow-like crushed ice.
  • Heating cycle.
Cons
  • Can warm up ingredients during the blending process.
  • Makes foamy smoothies in 40-ounce jar.
  • Blades not dishwasher-safe.
8.0 Smoothies/Protein Shakes

The NutriBullet Rx is great for smoothies and protein shakes. It makes impressive, silky smoothies in its 32-ounce main jar and does an alright job in its 40-ounce additional jar. It also makes snow-like crushed ice, which is nice if you like to add it to your smoothies. It's well-built and very easy to clean by hand as well. There's even a one-minute 'Smoothie' preset, but unfortunately, you may need to run it more than once to fully blend kale and frozen banana. This can warm up the ingredients a bit, especially if you're using the additional jar.

Pros
  • Easy to clean by hand.
  • Snow-like crushed ice.
  • Impressive smoothies in main jar.
Cons
  • Can warm up ingredients during the blending process.
  • Makes foamy smoothies in 40-ounce jar.
8.6 Ice Crushing

The NutriBullet Rx is amazing for ice crushing. It's well-built and makes snow-liked crushed ice quickly. The manufacturer says you shouldn't fill the jar more than 1/4th of the way up with ice, so it's not ideal for making frozen drinks for a crowd. However, if you only need enough for a few cocktails, it should work very well.

Pros
  • Snow-like crushed ice.
  • Good build quality.
Cons
  • Small capacity for ice.
6.6 Soups

The NutriBullet Rx isn't intended for blending already-hot ingredients, like roasted vegetables. However, it has a mode advertised to heat cool ingredients to 70 degrees Celsius in seven minutes, so you can use it to make soup out of raw ingredients or cooked ones that have cooled. The blender can incorporate fibrous greens like kale into a silky blend. It's also well-built and easy to clean.

7.4 Professional Use

The NutriBullet Rx is decent for professional use. It's sturdy, and its motor base has some metal components. The biggest jar has a 40-ounce capacity, which is quite big for a personal blender, and it's versatile since it can heat ingredients in its 32-ounce pitcher, make snow-like crushed ice, and even produce okay almond butter. It's also easy to clean by hand, and the jars and lids are top-rack dishwasher-safe. The design can be a little inconvenient, though, since it's easy to leave powered on by accident, and the power button itself doesn't feel very well-made.

Pros
  • Easy to clean by hand.
  • Good build quality.
Cons
  • Blades not dishwasher-safe.
  • Small capacity for ice.
  • 6.7 Multi-Purpose
  • 8.0 Smoothies/Protein Shakes
  • 8.6 Ice Crushing
  • 6.6 Soups
  • 7.4 Professional Use

The NutriBullet Rx looks like a bigger version of personal models like the NutriBullet Pro+. With its main jar attached, it's taller than the full-size NutriBullet Blender Combo, but it should still be easy to store in a cupboard or on your kitchen counter. You can also remove the jar from the base for easier storage.

Build Quality

The NutriBullet Rx has a good build quality. Unlike other NutriBullet models that we've tested, the transmission is a mix of metal and plastic, and the gear that turns the blade assembly is solid metal.

The rest of the motor body is mostly made of decently solid plastic, though it wobbles a bit when set on a counter and the power button on the side feels cheap. It's also a bit bigger than other NutriBullet models that we've tested, and the larger blade assembly can be difficult to unscrew from the jars, especially for people with smaller hands. However, it comes with a 'Blade Remover' tool that fits onto the blade assembly and makes it easier to remove. Still, it can be hard to keep a good grip on the jar at the same time, and you may need to put the jar under your arm while you use the tool.

The NutriBullet Rx comes with one blade assembly with four dull blades. Two are angled slightly upward, and two are angled slightly downward.

The manual says you should clean them with soap and water, not placed in a dishwasher, and that you should service the blade assembly every six months or as needed. However, you shouldn't disassemble it. The NutriBullet website also recommends replacing the blade assembly periodically and sells replacements.

The NutriBullet Rx comes with two lids for its main jar: a two-part lid whose removable centerpiece doubles as a 2-ounce measuring cup, and a pitcher lid that opens and closes with a knob on top.

There's also a lip ring that makes it more comfortable to drink from the jars, and a resealable lid so you can easily store what you make. These and the pitcher lid fit on any jar. The jars and lids are also top-rack dishwasher-safe.

The NutriBullet Rx has a simple design. There's a small power button on its side and one in front that changes the blending mode. Unfortunately, since you don't need to turn the power off to stop the blender, it's easy to leave it powered on accidentally. If you forget to turn it off, the blender automatically starts the next time you place one of the jars on the base, which can be an unpleasant surprise.

There's no way to control the speed of NutriBullet Rx, and it's advertised to have a single blending speed. However, when you first turn it on, it blends at 25800 RPM for about 30 seconds before decreasing to 2500 RPM for the rest of the blending cycle.

Unprocessed Almonds/Chunks
Yes

The NutriBullet Rx makes alright almond butter. It can process most almonds into a very spreadable mixture, but it takes about four one-minute 'Smoothie' cycles. Initially, you may need to stop the blender before the cycle finishes and use a spatula to push the ingredients towards the blades. You also need to stir the blend after each cycle to help the ingredients get evenly processed. The manufacturer recommends allowing the blender to rest for 30 seconds after every minute of blending and rest for five minutes after three consecutive cycles. While it's not the fastest or easiest process, and there are a few unprocessed chunks left under the blades, the almond butter is sticky and pleasant to eat. It's also noticeably warm, likely because of friction from the blades.

Smooth

The NutriBullet Rx makes great smoothies in its main pitcher. It fully processes frozen bananas and raw kale so that no grains or pieces are left. However, you need to run the one-minute 'Smoothie' preset twice for all the ingredients to be processed. The result is smooth, thick, and pleasant to drink, but also a bit airy and warm, probably because the motor base heated the ingredients slightly.

The NutriBullet Rx makes an okay smoothie in its 40-ounce additional jar. It takes three one-minute 'Smoothie' cycles to process the kale and frozen bananas. The ingredients are fully blended, but the smoothie is grainier than the one made in the main jar and unpleasantly warm.

Ice Quality
Snow Like

The NutriBullet Rx is fantastic for crushing ice. It makes snow-like crushed ice in about two minutes. The manufacturer says not to fill more than 25% of a jar's capacity with ice, so you can only crush about four ice cubes at once in the main jar. Each batch takes about 15 seconds to process, so it takes around two minutes to crush 12 ice cubes. However, because of the small amount you can blend at once, it's not ideal if you need a lot of crushed ice.

The NutriBullet Rx has two modes to select by pushing the 'G Button' on its front. 'Smoothie' mode is a one-minute cycle that starts at the blender's maximum speed and drops to a lower speed after 30 seconds. It's the default setting, and you can activate it just by turning on the blender. 'Souperblast' mode is advertised to heat ingredients to 70 degrees Celsius over seven minutes. You can activate it by holding down the button for two seconds. The 'G Button' is lit blue when the blender is on but not running, green during a 'Smoothie' cycle, and orange when you're running 'Souperblast' mode. Both modes act as timers that stop the blender after a set amount of time.

Almond Butter Cleaning
Simple

The NutriBullet Rx is easy to clean. The process is really simple when you're working with liquidy ingredients like for a smoothie. You can completely clean the jar by filling it about 2/3rds full with water and a drop of soap and blending it for about 30 seconds. If you use the two-part lid, it needs to be rinsed separately and wiped with a sponge. If you make almond butter, you can use the same 30-second blend to get the jar mostly clean, then use a sponge to quickly remove any residue left on the jar or lid. Sticky or dry ingredients tend to get stuck under the blades, though, so you may need to use the included brush to clean them properly.

If you're working with stubborn ingredients and worried about a difficult clean-up, you may want to use the main jar for your recipe since it's open on both ends once you remove the blade assembly.

The NutriBullet Rx stands out from other NutriBullet models because of its heating mode, 'Souperblast', a seven-minute cycle that heats ingredients. This isn't considered a heating element because the heat comes from friction from the blades, unlike blenders like the Ninja Foodi Cold & Hot Blender. It's intended for making recipes like soup and sauce from cool or room-temperature ingredients. To use the heating mode, you have to use the main jar with its two-part lid. The other lid and jars aren't safe to use because they don't allow steam to escape. However, 'Souperblast' isn't advertised for blending already-hot ingredients. According to the manufacturer, the only NutriBullet blenders that you can use to blend hot ingredients like coffee are full-size models, including the NutriBullet Blender Combo.

Differences Between Sizes And Variants

The NutriBullet Rx comes in one color: Black. You can see the label for the unit we tested here. If you come across another variant or your NutriBullet Rx is different, please let us know, and we'll update our review.

Compared To Other Blenders

The NutriBullet Rx is a full-size, bullet-style blender with a similar appearance to other NutriBullet blenders like the NutriBullet PRO 1000, although it's bigger and has a better build quality. Like the Blendtec Designer 725, it has a dedicated mode for heating cool ingredients using friction from the blades. It can crush ice, but the NutriBullet Pro and the NutriBullet Pro+ are much better for making smoothies.

If you want to see other options, look at our picks for the best bullet blenders, the best personal blenders, and the best blenders for smoothies.

NutriBullet Pro

Depending on your needs, you may prefer either the NutriBullet Pro or the NutriBullet Rx. The Pro is much smaller and makes significantly better smoothies in both of its jars. On the other hand, the Rx can crush ice on its own. It can also warm up cold ingredients, it's easier to clean by hand, and it comes with three jars rather than two.

Ninja Foodi Power Nutri DUO

The Ninja Foodi Power Nutri DUO is better than the NutriBullet Rx for most purposes. The DUO does a much better job of making almond butter and smoothies. It's also much easier to clean by hand, and its blades are dishwasher-safe, unlike the Rx. On the other hand, the Rx has a preset for heating ingredients.

Ninja Nutri Ninja Pro

The NutriBullet Rx is better for most purposes than the Ninja Nutri Ninja Pro. It has a much better build quality and makes significantly better-blended ingredients. It can also warm up ingredients for recipes like soup. On the other hand, the Ninja is much easier to clean by hand.

NutriBullet Pro+

The NutriBullet Rx and the NutriBullet Pro+ have different strengths, and you may prefer either depending on your preferences. The Pro+ makes significantly better-blended smoothies in both of its jars, and it's much easier to clean by hand. However, the better-built Rx can crush ice on its own, unlike the Pro+, and it has a preset for heating ingredients.

NutriBullet Smart Touch Blender Combo

The NutriBullet Smart Touch Blender Combo and the NutriBullet Rx have different strengths, and you may prefer either one. The Blender Combo's main jar has a much bigger capacity, and it makes better-blended smoothies and smoother, more spreadable almond butter. It can also hot blend. On the other hand, the Rx can crush ice, and it's easier to clean by hand. While it's not intended for hot blending, it has a dedicated mode for heating cooler ingredients.

Vitamix Explorian E310

The Vitamix Explorian E310 is better than the NutriBullet Rx. The Vitamix has a much better build quality and a bigger capacity. It has multiple speed settings and does a much better job of making smoothies, almond butter, and crushed ice. You can also use it for hot blending. On the other hand, the Rx isn't intended for blending hot ingredients, but it has a mode for heating cooler ingredients, unlike the Vitamix.
