310 Shake is a healthy meal replacement formula made with some of the finest natural ingredients in the world.

Imagine a supportive community of women working toward healthier lifestyles and a product that could help support their goals.

That’s what LadyBoss aspires to with its LEAN nutrition shakes.

LadyBoss LEAN comes in one flavor (vanilla cake) but is versatile and can be used in many recipes. We loved its older formula that contained soluble fiber and stevia, but its new formula is nothing to brag home about. Regardless, these shakes taste great, boast a decent nutrient profile, and are at a reasonable price.

Read on to learn more about LadyBoss LEAN shakes, including their nutrition, ingredients, key claims, value, and company history.


The Lady Boss Lean Shake comes in a Vanilla Cake flavor


LadyBoss likes to keep their LEAN shakes as simple as possible. They only offer flavor: vanilla cake. It has a great, sweet taste that tastes great as a nutrition shake or an ingredient to add to desserts and other foods!

However, LadyBoss LEAN advertises “unlimited flavor options” through their 61 protein shake recipes. With some effort and other ingredients, you can mix up flavors like café mocha, strawberry cheesecake, and “Butterfinger”, to name a few!

Plus, most people choose vanilla or chocolate when it comes to meal replacement shakes, so this is probably a safe bet for active women seeking a healthier lifestyle. In the future, it would be great to see additional specialty flavors from LadyBoss.

Read on to learn more about this meal replacement shake’s nutrient profile, including a breakdown of macronutrients, ingredients, allergens, and more.

Nutrition Facts

We’ll be diving into the nutrient profile in much greater detail shortly. Here’s a snapshot of the nutrition facts for LadyBoss LEAN shakes.

Laedy Boss Lean Shake Nutrition Facts Label


Each scoop of LadyBoss LEAN contains 110 calories, making it relatively low in calories for a meal replacement shake. 

This means that it’s well-suited for women who want to lose weight or cut back on their calories. And, for those who aren’t necessarily seeking weight loss or looking to replace full meals with these shakes, they can add it to a base like almond or coconut milk for extra calories.

It’s important to understand that calories aren’t evil! Your body needs calories from fat, carbs, and protein to carry out essential functions. 

Additionally, when it comes to calories, there is no one-size-fits-all number. Everyone’s calorie requirements vary, depending on lifestyle factors, age, sex, and more. Talk to your Registered Dietitian if you need a recommendation on how many calories your body needs. The USDA has a calculator to help with this, as well. [2]


Each LadyBoss LEAN nutrition shake contains 1 gram of total fat, of which 0.5 grams are from saturated fat.

This means that these meal replacement shakes are pretty low in fat. The little bit of fat in each shake likely comes from the powdered milk ingredient, which gives these shakes a creamy taste and texture.

Healthy fats like polyunsaturated and monounsaturated fats are great for your heart. However, saturated fats from sources like milk can contribute to your “bad cholesterol” (LDL) [3], so if you plan on drinking several LadyBoss LEAN nutrition shakes per day, try to be cognizant of the saturated fat content!

Total Carbohydrates (Carbs), Sugar & Sweeteners

Total Carbohydrates

Each LadyBoss LEAN shake contains 10 grams of total carbohydrates. This makes it a relatively low-carb meal replacement shake.

This total typically comes from a combination of dietary fiber and total sugars.

Dietary Fiber

Unfortunately, there are 0 grams of dietary fiber in each LadyBoss LEAN nutrition shake.

The previous formula contained soluble fiber (Fibersol®). With the change in formulation, LadyBoss LEAN took away this great ingredient. Soluble fiber helps digest food more slowly and supports satiety, [4] so it’s disappointing to see this ingredient removed in the “new and improved” formula. 

Added Sugars

There are 0 grams of added sugar in each LadyBoss LEAN meal replacement shake, which supports the USDA Dietary Guidelines to limit added sugars to 10 percent of your daily calorie intake. [5]

With no added sugar, these shakes are great options for people looking to manage their blood sugar and insulin, as well as anyone living with diabetes. There are 5 grams of total sugars that are naturally occurring from its ingredients.

Instead, the sweetness in these nutrition shakes comes from sucralose and acesulfame K, which we’ll explain below.

Natural & Traditional Sweeteners

There are no natural sweeteners in LadyBoss LEAN shakes. The original formula contained stevia, which is a plant-based sweetener, which provided a reasonable amount of sweetness.

Instead, the new LadyBoss LEAN shakes contain the following artificial/traditional sweeteners:


  • Sucralose
  • Acesulfame potassium (“Ace K”)


Sucralose and acesulfame potassium are traditional sweeteners that are approved for use in the United States. [6] They’re both much sweeter than sugar, so they’re called “high-intensity sweeteners”. 

Unlike sugar, both these sweeteners have zero calories and carbs, so they’re popular additives to foods and beverages. In large amounts, their safety has come into question, so some individuals choose to avoid them altogether. However, in the small quantities that LadyBoss LEAN shakes contain, it’s unlikely to have the same impact on your health. 

Some people also find the taste of artificial sweeteners overpowering, so if you typically don’t like foods with artificial sweeteners, you probably won’t like these shakes.


Each LadyBoss LEAN shake contains 15 grams of protein. As far as quantity goes, this is on par with most of our top-rated shakes and makes it a great source of protein!

The sources of protein in LadyBoss LEAN are grass-fed, non-GMO whey protein isolate and concentrate

Whey protein is derived from dairy products and contains essential amino acids to help your body perform functions like building and storing muscle. It’s a popular and affordable protein option for meal replacement shakes like LadyBoss LEAN. Consuming more protein can help women who use this product feel fuller and retain muscle, even if they are engaging in workouts and calorie deficit!

As far as the grass-fed and non-GMO claims go, it’s a matter of personal preference rather than nutritive value. The nutrient profile of a GMO whey protein blend versus a grass-fed, non-GMO blend is not significantly different; but, some people choose grass-fed options and prefer to not have genetically modified organisms in their food. We can appreciate LadyBoss for considering those who prefer “cleaner” protein options in this sense.

Vitamins and Minerals

LadyBoss LEAN shakes have a pretty robust vitamin and mineral profile, including everything that you’d expect from a women’s multivitamin supplement:


  • Vitamin D: 2.6 mcg (15%)
  • Calcium: 170 mg (15%)
  • Iron: 7.2 mg (40%)
  • Potassium: 90 mg (2%)
  • Vitamin A: 390 mcg (45%)
  • Vitamin C: 15 mg (15%)
  • Vitamin E: 7.6 mg (50%)
  • Thiamin: 2.5 mg (210%)
  • Riboflavin: 0.58 mg (45%)
  • Niacin: 5.1 mg (30%)
  • Vitamin B6: 0.5 mg (30%)
  • Folate: 95 mcg DFE (25%) – prevents birth defects and promotes healthy nails
  • Vitamin B12: 1.7 mcg (70%)
  • Biotin: 75 mcg (250%) – may support healthy hair, skin, and nails
  • Pantothenic Acid: 2.4 mg (50%)
  • Phosphorus: 120 mg (10%)
  • Iodine: 39 mcg (25%)
  • Magnesium: 55 mg (15%)
  • Zinc: 3.8 mg (35%)


One benefit of drinking these shakes several times per day is that you may be able to ditch your multivitamin supplement if you’re currently taking one. This would especially be true if you’re already getting essential vitamins and minerals from your meals. Check with your physician before you start or stop any supplement.


LadyBoss LEAN does not disclose its full ingredients list online on their website. The imagery on Amazon did not include a picture of the supplement facts, either. 

The easiest way to look at the ingredients before buying is to look at customer reviews. One of the recent reviews included this snapshot of the ingredients: 

Lady Boss Lean Shake Ingredients List

Overall, the ingredients include the following:


  • Protein: Grass-fed, non-GMO whey protein isolate, and concentrate


    • Fillers: Maltodextrin, xanthan gum (thickening agent)


  • Vitamins: sodium chloride, dicalcium phosphate dihydrate, magnesium oxide, ascorbic acid, D-alpha tocopherol acetate, pyridoxine HCl, niacin, zinc oxide, beta carotene, cholecalciferol, D-calcium pantothenate, thiamine, riboflavin, folic acid, biotin, potassium iodide, cyanocobalamin


    • Enzyme to help digest protein: ProHydrolase®
    • Artificial sweeteners: sucralose, acesulfame potassium


  • Powdered milk


Although it’s great to see vitamins, digestive enzymes, and whey protein in this formula, it seems that LadyBoss has recently changed their formula to include fillers and artificial sweeteners instead of their old formula, which contained stevia and soluble fiber (Fibersol®).  

The “no artificial sweeteners” claim has been removed from the front of the packaging since the formulation change, but this can be deceiving for those who have been buying LadyBoss LEAN shakes for years. Many of the low (1-star or 2-star) ratings on this shake seem to be a result of their formulation change, as many people are not happy with the ingredients.

However, the old formula contained fructose, while the new one does not, so that’s an improvement that we’re excited about.

Allergens and Warnings

LadyBoss LEAN shakes contain milk from the whey protein isolate and concentrate. Most lactose-intolerant individuals can drink whey, but you may want to check with a Registered Dietitian before drinking this shake regularly.

As far as other allergens, these meal replacement shakes are manufactured in a plant that also processes milk, egg, soybeans, shellfish, fish, tree nuts, wheat, and peanuts.

As with any other supplement, pregnant or nursing mothers or individuals with medical conditions should check with their doctor before starting this supplement.

Now that you’ve understood LadyBoss LEAN shakes’ nutrient profile, let’s explore their health and marketing claims, price, and ways to enjoy so that you can make an informed decision!

Key Health and Marketing Claims 

There are four key health and marketing claims on the nutrition label to dive deeper into:


  • High-protein meal replacement


    • With 15 grams of whey protein in every serving, this claim is true. A healthy, balanced meal would typically consist of a lean protein, so this meal replacement shake offers that and more.


  • Promote immune system health


    • This claim is somewhat misleading. LEAN does include vitamins A, C, E, and enzymes to help break down nutrients. However, there is no specific evidence that it supports immunity, at least any more than a multivitamin that contains those vitamins would. 


  • Control sweet cravings


    • This claim is somewhat true! There are no specific ingredients in this shake that are designed to curb or control cravings or hunger. However, since it tastes like dessert, it may be enough to stave off some cravings as you’ll feel like you’ve indulged in dessert.


  • Support fat loss
  • No substantial evidence supports this claim. Although a healthy, nutrient-dense diet combined with exercise, can support fat loss, drinking these shakes in absence of making other healthy lifestyle changes would not result in fat loss.



There are different ways to buy LadyBoss LEAN: 

  • Through Amazon, each bag of LadyBoss LEAN is $69, which means that it costs $2.30 per serving (there are 30 servings in each 1.91-pound pouch). It’s eligible for Prime shipping, so this would be a great bet for anyone with Prime membership to have it show up within 2 days.
  • Through LadyBoss, each bag of LadyBoss LEAN is $59.95, which brings it to a lower cost of $1.99 per serving. LadyBoss offers free 2-to-5-day shipping, with some delays during COVID-19.

For those who know they love LadyBoss LEAN and want a regular supply while saving some money, LadyBoss’ CLUB monthly Subscribe and Save program might be the best option. It offers the following perks (only available directly through LadyBoss):

  • 15-20% off first order and future deliveries ($1.65 per serving)
  • Refer friends and get free products
  • Free bonus sticker or mystery item
  • Early access to special flavors
  • Customer support, including customer service, cancelation, and switch dates or product anytime

Of course, this is a subscription program, so you may want to consider how often you need your supply of shakes and whether it will make sense for your financial situation.

Additionally, any purchase through LadyBoss includes the following free bonuses, which provide support to those truly looking to make lifestyle changes beyond drinking meal replacement shakes daily:

  • Recipe book with 61 shake recipes
  • 28-day challenge access from weight loss coaches
  • Workout plan and meal plan
  • Access to support community

Ways to Enjoy LadyBoss LEAN

According to LadyBoss, this meal replacement shake can be consumed up to 3 times per day. 

For maximum weight loss results, their directions are to replace 2 meals per day with a shake and have your third shake as a snack or after a workout. [1]

Here are the different ways to enjoy LEAN shakes throughout the day:

  • Breakfast – to kickstart your metabolism 
  • Post-workout – to fuel your muscles after exercise
  • Snack – when your cravings kick in, drink a shake for a guilt-free, delicious snack
  • Healthy baking – use the powder in a variety of recipes including cookies, waffles, and brownies
  • Evening meal – feel fuller in the evening and skip unhealthy snacks

You should also still try to have one balanced, nutritious meal that consists of lean proteins, non-starchy veggies, and whole grains in addition to your LadyBoss LEAN shakes.

Company Information

LadyBoss is a women’s health and weight loss specialty company that offers weight loss supplements, sleeping aids, energy-boosting supplements, a coaching program, and more. Its online community includes over 280,000 customers. [7]

The company was founded in Albuquerque, New Mexico, by entrepreneurs Kaelin and Brandon Poulin, who are passionate about “[helping] women across the world lose weight while loving themselves again”. 

Although a relatively new company that’s been in business for just over six years, its awards include “#1 best seller in women’s health” on Amazon, “#1 bestseller” on Barnes & Noble, and Stevie Awards including Fastest Growing Company of the Year and Best Consumer Product of the Year. It boasts over 842 five-star reviews, 314,915 customers, and 40 million shakes served since its creation.

According to LadyBoss’ Better Business Bureau profile, it is rated an A+, which is an improvement over the years. However, there are still quite a few complaints around shipping time, cancelations, returns, and refunds that dissatisfied customers and LadyBoss HQ are still working through for orders through their website. [8] If you’re concerned about guaranteed refunds and returns, you may want to look at other purchasing channels such as Amazon or eBay, rather than buying from LadyBoss directly.

The Bottom Line

From an ingredient quality perspective, LadyBoss LEAN’s newer formula isn’t as impressive as its older one that offered Fibersol® soluble fiber and stevia sweetener. 

However, the great taste of this meal replacement shake remains unchanged. It’s also still low in calories, low in fat, low in carbs, and high in protein, making it a great choice for anyone looking for a healthy but dessert-like meal replacement shake or snack!

Each LadyBoss LEAN shake costs $2.30 per serving, with cost-savings opportunities if you subscribe to their club program.
