Based in Las Vegas, 310 Nutrition sells a variety of products that are largely geared toward weight loss. To that end there are fat burners, appetite suppressants, metabolism boosters, and a huge array of other ways to achieve slimmer waistlines. Their meal replacement shake — which is just called 310 Shake — is meant to be taken once or twice per day and the company is very proud of the product, claiming that “your best life starts with the best meal replacement shakes.”

So what’s in it?

The 310 Meal Replacement Shakes offer a tri-plex blend of protein to control hunger and promote muscle growth.


310 Shake Nutrition & Ingredients

We picked up the Salted Caramel flavor and there are 90 calories in one serving: 15 grams of protein, 7 grams of carbohydrates (5 grams of fiber, no sugar) and 1.5 grams of fat (no saturated fat).

As far as micronutrients go, there is about 30 percent of your recommended daily intake for a pretty wide variety of vitamins and minerals: Vitamin A, C, D, E, B-vitamins, iron, magnesium, zinc, and others.

This is a plant-based shake with the protein coming from pea, rice, and hemp. There’s also a fiber blend of soluble fiber, waxy maize, and xanthan gum; a greens blend of organic green vegetables; and a billion probiotic bacteria from lactobacillus acidophilus.

This is all-natural. The flavor comes from natural flavors, stevia extract, and salt. There’s no sugar, dairy, soy, eggs, nuts, or gluten.

310 Shake Benefits & Effectiveness

First off, this is a very low calorie meal replacement; it’s unusual to find one that’s under 100 calories. It’s also very low in fat, with just 1.5 grams per serve. And while 7 grams of carbs (about half of the protein count) may not seem that low, 5 grams come from fiber, so it’s low in net carbs.

What that means is that despite claiming to be a great meal replacement, this isn’t a dense source of carbs and fat, macronutrients we need throughout the day. That might not be a big deal, but it does mean you may need to ensure you consume carbs and fat in other meals.

As far as nutrition goes, there’s a good 30 percent of most of your daily nutrients. That’s pretty good news, but you will need to ensure you’re getting plenty of fruits and vegetables to properly meet your recommended daily intake.

This is especially true since, and this is important, the 310 Shake is low in potassium (1%) and there’s no mention of Vitamin K, manganese, chromium, or choline.

But a big advantage it has is the focus on digestion, with a billion probiotic bacteria and a dose of prebiotic fiber as well.

310 Shake Price

The price fluctuates, but you can typically pick up a bag of 28 servings for about $70, or $2.50 per serving. That’s relatively expensive for a meal replacement shake, but you can save money by subscribing to a monthly shipment, which lowers the price by 5 to 10 percent, or by picking up a “kit” that includes a variety of other products.

310 Shake Taste

I was pretty surprised with how good the Salted Caramel flavor tasted. For a product with zero sugar and zero artificial sweeteners, I was skeptical. But it tasted pretty darn good, even with just natural flavors and stevia. It’s a little mild, but it’s still very convincing and if you can spare the calories, it’s excellent with milk. Note that this flavor is a higher in sodium than others, with one scoop providing 370mg or 15 percent of your daily intake.

The Takeaway

The 310 Shake is less about replacing a whole meal than it is with facilitating weight loss through very nutritious protein shakes, and in that respect it may succeed. I also liked the fact that it comes with a dose of probiotic bacteria and prebiotic fiber; these are foods that few people consume every day and I respect a meal replacement shake that delivers them. It doesn’t have every micronutrient we need — remember that it has practically no potassium or Vitamin K — but it gets the job done and it tastes good while it’s at it.

Nick is a content producer and journalist with over seven years’ experience reporting on four continents. His first articles about health were on a cholera outbreak in rural Kenya while he was reporting for a French humanitarian organization. His next writing job was covering the nightlife scene in Shanghai. He’s written on a lot of different kinds of things, but his passion for health ultimately led him to cover it full time.Shanghai was where he managed to publish his first health related article (it was on managing diarrhea), he then went on to produce a radio documentary about bodybuilding in Australia before he finished his Master’s degrees in Journalism and International Relations and headed to New York City. Here, he’s been writing on health full time for more than five years for outlets like Men's Health, VICE, and Popular Science.Nick’s interest in health kind of comes from an existential angle: how are we meant to live? How do we reach our potential? Does the body influence the mind? (Believe it or not, his politics Master’s focused on religion.)Questions like these took him through a lot of different areas of health and fitness like gymnastics, vegetarianism, kettlebell training, fasting, CrossFit, Paleo, and so on, until he realized (or decided) that strength training fit best with the ideas of continuous, measurable self improvement.At BarBend his writing focuses a little more on nutrition and long-form content with a heaping dose of strength training. His underlying belief is in the middle path: you don’t have to count every calorie and complete every workout in order to benefit from a healthy lifestyle and a stronger body. Plus, big traps are cool.
