Trying to lose weight in a hurry can be a lot more challenging than most people make it out to be, which is why you need to be 100% sure that you’re always taking advantage of the best solutions available on the market to give you every edge and every advantage possible to lose weight.

Meal replacement shakes like the IsaLean Shake, and the shakes from Herbalife are sold to help folks lose weight, though people who lose weight at a gradual, steady pace are more likely to keep the weight off than people who lose weight quicker.

The kind of meal replacement shakes that give you the nutrients you need to fuel your body and the kinds of shakes that will curb your appetite and help you fight cravings.

The odds are pretty good that you have settled on moving forward with one of these two amazing products, but how do you know which one is best for your specific needs?

The IsaLean Shake​

The first thing that you’re going to notice about the IsaLean Shake solutions out there is that they are 100% whey protein-based products.

This is a tremendously efficient protein that is going to be rapidly absorbed in your body, and it’s going to work to fill you up while at the same time providing your muscles with everything they need to recuperate and recover faster.

You’re also going to find this meal replacement shake to be loaded with more vitamins, more minerals, and more nutrients than the Herbalife solution – helping you feel full longer, energized, and able to tackle the day in front of you without any of the lethargy or fatigue you might have been fighting through previously.

​At the same time, you’re also going to be pretty shocked at just how much more money you have to pay to take advantage of the same amount of IsaLean Shakes. It’s almost 3 times more expensive than the Herbalife product, and you’re going to need to break down whether or not this solution fits your budget.

You should also know that Isagenix has prepared 9 days to cleanse and 30 days of cleansing programs, though a 2015 review concluded that there was no compelling research to support the use of cleansing diets for weight management or eliminating toxins from the body.

The Herbalife Formula 1 Shake​

Even though the Herbalife shakes aren’t quite as rich in vitamins, minerals, and essential nutrients as the Shake options mentioned above, they take advantage of a soy-based protein instead of the whey-based protein – but that does not make them allergen-free: soybeans and milk are both major food allergens, and this page’s comparison table lists the Herbalife shake as not dairy free, so people with food allergies should read labels.

This soy-based protein also allows the folks at Herbalife to produce these shakes much more inexpensively and pass the savings to you as the consumer.

Some have mentioned that the Herbalife products are a lot tastier than the IsaLean Shakes out there, so your mileage may vary!

Now let’s dig deeper into comparison: IsaLean Shake VS. Herbalife Formula 1 Shake.​

Complete Comparison: Isagenix vs Herbalife

The above table shows the percentage of daily intake for Vitamins & Minerals based on a 2000 calorie diet.

Which one has better hunger blockers, Isagenix or Herbalife?

IsaLean Shake

• As a hunger blocker, the shakes use chromium and 8g of fiber.
• The results are pretty good. The shake filled me up, but it didn’t keep me as full as some of the other shakes that I have tried in the past.
• A couple of times after I drank a shake, I ended up eating a small snack within a couple of hours to get me through to my next meal.
• So, it definitely wasn’t the best hunger blocker, but it wasn’t the worst either.
• You can expect it to keep you full for around 2 hours.

Herbalife Formula 1

• Honestly, this doesn’t do it.
• The shake has 3-4 grams of fiber per serving, and that’s not enough.
• It’s not so much a “shake” as it is a “milk flavoring packet.”
• Primarily, it filled me up to the same extent a 6oz. A cup of milk does.
• If you plan to use these shakes as a meal replacement, you will need to add some berries or anything else you can find to it.
• Otherwise, it’s barely more than a snack.

Which one has more nutrients, Isagenix or Herbalife?

IsaLean Shake

• Before anyone gets upset about my rating, let me explain myself. These shakes are nutritious.
• I rate nutrition regarding weight loss as a meal replacement option, not as a protein shake. The shake has a proper balance of minerals and vitamins (ranging from 30% to 150% of your daily intake). Plus, 8 grams of fiber is pretty impressive.
• If you want to get the best use of the 24 grams of protein, you will have to combine exercise with this shake. This much protein is the reason these shakes contain such a high number of calories.
• If the body does not process a protein, it will be stored as fat. Unless you are into strenuous workouts or heavy weightlifting, this amount of protein will probably be too much for you.
• Typically, you want 12 to 18 grams of protein per meal. (Women stay at the lower end and men to the higher end.) Isagenix IsaLean Shakes has 11 grams of sugar in each serving, which is a tad higher than I like. Of course, the old formula had even more sugar than this, so it’s a pretty good improvement.

Herbalife Formula 1

• While the shake is low in calories, which is great, it lacks pretty much everything else.
• They only contain around 25% of your RDI of minerals and vitamins, which isn’t horrible, but it isn’t all that great either.
• Plus, the 9 grams of protein is a tad low, while the 9 grams of sugar per shake is a bit high.
• So, it’s not horrible on nutrients, but it doesn’t come close to some of the other shakes I have reviewed.

Which one is more tasteful, Isagenix or Herbalife?

IsaLean Shake

• With higher amounts of sugar, you will get a better-tasting product, so I was quite impressed with the taste of the Creamy Dutch Chocolate shake.
• However, the high amount of protein resulted in that unavoidable “protein drink aftertaste” that nobody cares for.
• All in all, though, the shakes are pretty good. After trying the new reformulated Isalean Pro shakes, I realized that they have gotten better and moved up in the rankings.

Herbalife Formula 1

• When you are talking about shakes, there are only two flavor choices.
• They can be packed with sugar (as of late, around 16 grams per serving has been the norm for a tasty shake), or they can use a tiny amount of a 0 calories sweetener, such as Sucralose.
• Herbalife opted to take the middle road and use a small amount of real sugar. The taste suffers as a result.
• I remember that I referred to the shakes as “milk flavoring packets” earlier, but honestly, that was a bit generous.
• The shakes I tried were both vanilla flavored, but that’s not quite what they were.
• The taste was more like milk with a “vitamin-y” aftertaste. When I tried Allergen Free, it was even worse. It wasn’t good.

Which one has better value, Isagenix or Herbalife?

IsaLean Shake

• For a 14 day supply of Isagenix shakes, you will spend around $52.
• Each shake ends up costing you about $3.71.
• For me, the biggest issue with these shakes has always been the high cost. Sure, they are good, but not everyone can afford them.
• Now, you can become a part of their MLM program and get shakes that cost slightly less than $3 per serving if you’re planning on selling them to family and friends.

Herbalife Formula 1

• For a 30 serving tub, you only spend $35, making each shake an extremely affordable $1.17 per shake. That’s an incredible value!
• Keep in mind that I didn’t make my purchase through the official website. Instead, I went over to Amazon and bought them a la carte.
