Lady Boss Lean is a protein shake that claims to support fat loss, provide essential nutrients, and boost immune system health in women. Lady Boss, the company behind this product, states that this supplement was created for women who struggle with eating healthy due to time constraints and cravings.

Everybody and their mothers have heard about diet shakes. These liquid meals are touted as the “saving grace” of weight loss. They claim that with just a diet shake a day, you can see the pounds melt off with little to no effort.

Unfortunately, the weight loss supplement world is full of broken promises. Given that the FDA does not regulate supplements, manufacturers can sort of claim whatever they want on the product labels. Therefore, there is a lot of false advertising in the supplement industry. 

Lady Boss Lean is one diet shake that claims to have “cracked the code” on 54 different weight loss ingredients. That is a pretty big claim, and it would be nice if it were true. So today, our Lady Boss Lean review will determine if they are legit or another broken promise from the weight loss supplement industry.

Our Lady Boss Lean review will discuss this supplement’s ingredients, acclaimed benefits, downsides, and more to help you make the best choice for your journey to a healthier weight.


Lady Boss Lean: Overview


Lady Boss Lean is a protein and vitamin shake designed to be a daily supplement for women. Lady Boss Lean claims it can help people lose weight quickly and get the max out of their gym workouts. It styles itself as an “ultra-premium” all-in-one nutritional supplement.

Lady Boss Lean Shakes are not meant to be used on their own. Lady Boss Lean is part of the “Total Transformation System,” which has 5 separate steps, each with a specific product. The 5 steps and products are:

  • Lady Boss Burn – Energize in the morning
  • Lady Boss Lean – Kickstart metabolism in the morning
  • Lady Boss Fuel – Energize for workout motivation
  • Lady Boss Recover – Rehydrate after a workout
  • Lady Boss Rest – Revitalize and rest

You might be thinking, “Does this mean I have to buy all 5 products?” Technically no. Lady Boss recommends taking Lean as part of this transformation process, but you can buy it separately. That’s good, too, because buying all 5 supplements would cost about $200 a month, which is quite a steep bill. 

Lady Boss Lean is designed to jumpstart your metabolism in the morning and keep it running all day. The ingredients contain a mixture of whey protein and other fibers. Interestingly enough, most of the studies linked to Lady Boss are about muscle mass gain, not weight loss. 

One more quick note: Lady Boss says it’s designed for women, but from our review, we think the ingredients are completely gender-neutral. Yes, guys, you can partake, too, and become a Lady Boss. 

Who Makes Lady Boss Lean?

Lady Boss Lean is made, perhaps unsurprisingly, by Lady Boss, a women’s fitness and health company. Lady Boss was cofounded in 2014 by fitness professional and author Kaelin Tuell Poulin. Poulin was inspired to create Lady Boss after her fitness journey, and the company’s  dedication is to “help women across the world lose weight while loving themselves.” Lady Boss has sold products to over 100,000 women.


Lady Boss offers a neat coaching program where customers can call in to get weight loss advice and tips from “professionals.” Unfortunately, the only review of this part we found was one person who was not too happy with the coaching service. Also, their BBB page has a ton of customer complaints about their auto-billing cycle. The company seems to have responded to nearly all of them to their credit, but it’s pretty bad that so many exist in the first place. 

There are many complaints about poor customer service too, so if you buy from this company, you should probably be wary. 

How Does Lady Boss Lean Work?


Lady Boss Lean claims to be an ultra-premium all-in-one daily supplement that boosts your metabolism and gives you energy throughout the day. Unfortunately, it’s not clear how the supplement is supposed to work or what it actually does, as there is minimal description on the product website. 

It does make some claims that it can replace your breakfast and, as such, can work as a meal replacement shake, and it also says it can promote digestive health, presumably through the fiber content. Lady Boss Lean also claims to boost your immune system, which sounds like a medical claim with no backing. 

To be completely honest, the product page is full of extravagant promises and phrasings that lack full backing. We understand the need for branding language for marketing purposes, but you can overdo it. 

Lady Boss Lean Ingredients



Lady Boss Lean has quite a few ingredients, and here are some of the main ones we pulled off the product website.

  • Whey protein
  • Maltodextrin
  • Fibersol-2 
  • Digestive Enzymes
  • Vitamin premix (essentially a multivitamin)
  • Dried milk
  • Stevia

First off is the whey protein. Whey protein increases the timespan between the protein meal and the next time you get hungry. It is also a favorite muscle-building supplement ingredient, so seeing so much of it here is interesting. 

Fibersol-2 is a corn fiber that is mainly used as a bulking agent. Basically, this is the stuff that is supposed to promote healthy digestion. The fiber also helps you feel full. It’s also coupled with a cocktail multivitamin which we assume contains the basics like Vitamin C, D, B, and A. 

Dried milk, fructose, maltodextrin, and stevia are primarily for flavoring. Unfortunately, the animal-sourced milk content does mean Lady Boss Lean is not vegan. 

Lastly are the “digestive enzymes” that the manufacturer describes as “A patented blend of digestive enzymes that supports proper digestion of protein so you can enjoy all the benefits of LEAN without the discomfort, gas, and bloating associated with digesting other protein-rich foods.”

Is Lady Boss Lean Safe?


All noted side effects of Lady Boss are common with meal replacement shakes and include nausea, upset stomach, constipation, or gas. These side effects tend to disappear once you get used to taking the supplement. 

Where To Buy Lady Boss Lean And Cost


You can buy Lady Boss Lean from the company’s website, or you can buy it in some physical retail spots like Walgreens and Walmart. You can also buy some on Amazon. A 30-day supply costs about $69 but may vary by retailer. 

Diet Drink Alternatives

Now that you’ve learned a lot about Lady Boss Lean, you may wonder if there are other alternatives worth considering. 

Let’s take a look at some other diet shake alternatives:

Flat Tummy Shakes

Flat Tummy Shakes is another diet shake that we rate at a 3.7. They claim to help keep your tummy flat by controlling your appetite, kicking your cravings, and cutting weight. Flat Tummy Shakes offers a 4-week program at $89 and a 2-week program at $69.

ActivatedYou Morning Complete

ActivatedYou Morning Complete is a daily dietary supplement blend made to be dissolved into water or tea. Its formula includes a combination of prebiotics, probiotics, greens, and more. You can get a 30-day supply of ActivatedYou Morning Complete for $80.

Lady Boss Lean: Buy It Or Not?

Lady Boss seems like it could be a decent product if there weren’t such an unreliable payment scheme and expensive price tag attached to it. That goes double if you want to try the 5-step transformation plan, which costs about $200 a month.

The company claims that you can try Lady Boss Lean for 30 days with a 100% money-back guarantee; however, the refund and return policies offered by the company are even more complicated and may be a challenge for potential buyers.

Overall, we think Lady Boss Lean may be a diet shake worth trying as a meal replacement option as it contains vital protein and vitamins. However, we suggest saving your money for something more affordable and equally effective that comes from a more reliable company.
