GNC Lean Shake 25 Reviews For Weight Loss

What is Total Lean Shake 25?

GNC’s Total Lean is a line of products produced by GNC. These products are to help you reach your health and fitness goal (lose weight, feel great). These products are meal replacement shakes, RTDs, thermogenics, and bars.

Lean Shake 25 GNC’s take on, a meal replacement shake. The flavor I purchased was girl scouts thin mints. Is this protein worth your money? Let’s dive into the review.

Here are my questions I want to answer for GNC Lean Shake 25

  • Can Lean Shake 25 be a good alternative to BSN Syntha 6?
  • Does GNC Lean Shake work for weight loss?
  • Can Lean Shake be as effective at building and maintaining muscle?

Let’s get into the review.

Best Place to Buy GNC Lean Shake 25

I purchased GNC Toal Lean Shake 25 at Walmart in January. I couldn’t say no because a lot of other people had that itch to lose weight too!

  • 16 servings, $23.88, $1.49 per serving.

$24 may seem steep for 16 servings. But let’s compare to other outlets selling 16 serving containers.

If your goal is to lose weight and stay full, GNC Total Lean Shake may appear like a great option to reach your goals.

Value: 5. Upon first glance, $24 for 16 servings appears to be a great deal. Here’s the reason why GNC Total Lean Shake 25 is getting a 5. Low quality ingredients.

Is GNC Total Lean Shake 25 Spiked?

My steps are always the same when determining if a protein powder is spiked. Here are my steps I take.

  • Look at the nutrition facts for recovery blends.
  • Examine ingredient list for added amino acids.
  • Research for an amino acid profile on the label or website.
  • Finally contact supplement company and request an amino profile.

I had to contact GNC for an amino acid profile. Here is there response.

Unbiased GNC Total Lean Shake 25 Review, Thin Mint Edition
Lean Shake 25 has an unlisted amino acid

If new technology in protein manufacturing happens, then put it on the label. Optimum Nutrition does it… But if there are no products and manufacturing in protein powders, then how come no one else finding these advancements?

All proteins have amino acids, essential amino acids, and branch chain amino acids. To state that there is only one amino acid is misleading and is a red flag. If L-Carnitine is present in your product (it shouldn’t), how much L-Carnitine is in the product?

You could be thinking, “Could L-Carnitine can be beneficial for weight loss and exercise performance?”

There’s little evidence suggesting that L-Carnitine will increase fat oxidation. Plus, L-Carnitine is not a naturally occurring amino acid in protein powder production. So why have it in the product?

Let’s examine if L-Caranitine is a good at burning fat.

Is L-Carnitine A Fat Burner?

The article explains that while carnitine plays a role in fat burning during exercise, simply taking extra carnitine doesn’t necessarily lead to increased fat oxidation.

Recent studies suggest that long-term carnitine supplementation combined with carbohydrates might increase its levels in muscles, potentially aiding in fat use during light exercise and reducing muscle lactate at high intensity.

However, the key to fat loss is more related to the exercise itself rather than just taking carnitine supplements.

Protein Spiking: 1. It’s spiked. I didn’t get an amino acid profile. I was provided with misleading information. If L-Carnitine is in this product, it makes you wonder what other, nitrogen based ingredients are inflating the protein count of this product. The label doesn’t state that L-Carnitine is an occurring product.

GNC Lean Shake 25 Directions

Here are some keypoints about Lean Shake 25

  • Lean Shake 25 is a blend of whey protein concentrate, milk concentrate, then isolate.
  • L-Carnitine is in this product (as shared by the rep via email convo), but not listed in the ingredient list.
  • There is no lactase enzyme for you people who can’t digest dairy.

For the record, I had major GI issues drinking Lean Shake 25.

Ingredient Profile: 5. Small font to read on the label. When I see blended protein, I expect to see concentrate, casein, and isolate. Two concentrates and a splash of isolate isn’t a blend.

No Digestive enzymes are in Lean Shake 25. You will experience mild GI distress when you mix with water(bloating/protein farts). When you use Lactose free milk, you will experience the bloat.

L-Carnitine is in this product and is not listed on the ingredient list. This information was shared via email with a GNC Rep.

Is GNC Lean Shake 25 Healthy?

GNC Lean Shake 25 provides 25% of your daily intake of fiber. That’s almost half the fiber intake a person consumes on a daily basis.

Here’s the reason why you’re reading this review…

Is GNC Lean Shake 25 Good For Weight Loss?

“The helping hand when hunger strikes”

  • Hunger satisfying to help you fell fuller, longer
  • Well-balanced with high-quality protein (flag) & fiber 
  • Fortified for a low-carb diet
  • Delicious & healthy addition to your daily meal plan

This protein powder is well-balanced. What comes into question is “high-quality protein.” Most of this protein powder is filler. My standard for high quality protein is 80%.

The scoop is a nice touch in the protein. No more digging in the protein. When you actually use the scoop, you get more than enough of the powder outside the shaker.

Macro Composition: 6. Does this protein do as advertised, is it a “hunger-satisfying, high-protein meal replacement?” Yes. However, majority of this protein is FILLER.

I expect to see at least I would want to see 70% protein per serving. That’s the smallest amount for a high-quality concentrate.

As a meal replacement, it does the job. I wouldn’t recommend Lean Shake 25 post workout.

Does GNC Lean Shake 25 Taste Good?

My rule is if you see a picture, you better be able to taste the picture.

I’ve had my share of Girl Scout Thin Mints. I’d like to think I’m an authority when it comes to eating cookies.

When you shake it with water, you still get the flavor (AND TEXTURE) of a cookie. It’s okay. You’re drinking minty water with cookie crumbs.

What makes this protein shine is when you mix it with milk. Skim milk, 2%, or my favorite whole milk. You’ll be happy if you mix this protein powder with milk.

Flavor: 8. If you mix this with water, it’s a solid 7. Using water feels like you’re at the dollar store protein.

But when you use milk as your liquid, you’re drinking a Girl Scout cookie. Mix this protein with milk! When you shake it up with milk, the flavor profile competes with the respected proteins.

Is Lean Shake 25 Good For You?

Total Lean Shake 25, The Good

Lean Shake 25 excels in taste and hunger satisfaction. However, compared to BSN Syntha-6, known for its muscle-building capabilities, it serves more as a meal replacement than a muscle-enhancing supplement.

Lean Shake 25 main draw is being a meal replacement for weight loss purposes – more for the “shed the holiday weight” crowd than for serious gym enthusiasts.

Lean Shake 25 mixes great.

As shared, the goal of Lean Shake 25 is to help shed the holiday weight. Majority of people using Lean Shake 25 are most likely not fitness enthusiasts. Lean Shake 25 provides a good flavor profile.

Lean Shake 25, The Bad

The presence of fillers and the questionable protein quality, especially the undisclosed L-Carnitine, really takes away from its overall value. It seems more like a marketing ploy rather than a substantial nutritional supplement.

If you’re aiming for serious muscle gains or a high-quality post-workout shake, GNC Lean Shake 25 might not be your best bet. It might help in weight management, but there are probably better, more transparent options out there for muscle support and recovery.

Seeking clarity, I requested GNC’s amino acid profile. Surprisingly, GNC revealed the presence of L-Carnitine – an unlisted ingredient, raising questions about transparency and protein quality.

[We are] reviewing and updating formulas to bring you the most up-to-date advancements in the industry…Taking this into consideration, we want to confirm there is only one amino acid present…L-Carnitine

GNC Rep sharing L-Carnitine is an unlisted amino acid

This is the reason why amino profiles are important, knowing what’s in your protein. If L-Carnitine is not listed on the ingredient list.

After six trials, my verdict on Lean Shake 25 is mixed. Its efficacy as a meal replacement is overshadowed by concerns over protein quality and ingredient transparency..

3.4

Syntha 6 has more muscle building protein sources

Both protein powder do not offer an amino acid profile. Even though the lack of transparency hurts both brands. Syntha 6 didn’t provide conflicting information about their protein profile.

Furthermore, I did not experience any GI issues drinking Syntha 6.

The main reason why I did not finish Total Lean Shake 25 was due to the amount of GI issues experienced.

Best Vanilla Protein Powder for Weight Loss

Even though Lean Shake 25 offers more fiber per serving. You have to look at strictly what is known.

  • No GI issues when drinking Syntha 6
  • More flavor choices with Syntha 6
  • Clean mix everytime with Syntha 6
  • Robust protein sources with Syntha 6
  • Fewer ingredients with Syntha 6

Even though both companies did not provide an amino acid profile. Syntha 6 is the superior protein when compared to Total Lean Shake 25.

Other Protein Powder for Weight Loss
PR Breaker Hitpoint Ultra

If you want a great alternative that isn’t going to skimp on the protein with broken amino fragments. You want Hitpoint Ultra. Lower calories than Muscle Milk. Offered in 2 delicious flavors. Sometimes you can buy closed dated products at a discounted price. Visit PRBreaker.com to purchase (non-affiliate link).

Muscle Milk

Scored 84%. A two-blend protein of whey protein concentrate and milk protein isolate. You’re getting the best of both worlds. However, at 280 calories per serving, that’s hefty. Muscle Milk is best for building muscle instead of a weight loss shake. Purchase Genuine Muscle Milk.
