Slender Blend Review

The Slender Blend Review

Protein World is one of the fastest-growing supplement companies in the UK, with the Slender Blend being a staple supplement right from when the brand was created back in 2013.

The Slender Blend formula is marketed as the perfect protein supplement to help you lose weight, burn fat, tone up, and build and repair muscle.

The formula has both an original version that contains whey protein, and a vegan version that contains a mix of plant-based proteins (which is great to see for those that are plant-based).

Featuring probiotics, enzymes, and herbal extracts alongside the 23.2g of protein per serving, Protein World markets Slender Blend as the best supplement for added protein and essential micronutrients.

I’m really keen to take a closer look at this formula and see if the popular reputation of it really is worth it.

If you’re thinking of purchasing this formula or you’re also intrigued to take a closer look at it, check out my full Protein World Slender Blend review below.

Slender Blend First Impressions

As mentioned above, Protein World is without a doubt one of the most well-known supplement companies out there, especially in the UK. Therefore, the Protein World website is unsurprisingly sleek, sophisticated, informative, and educational.

A few things I really like about the Protein World website are the recipe pages, the blog, and the ‘Protein World Spotlight’ that showcases members of Protein World members and ambassadors.

Looking at the Slender Blend, I’m impressed. The packaging and branding all seems on-brand with Protein World and it definitely grabs your attention.

The only thing I’m slightly concerned about is the fact the formula is marketed as a meal replacement, as I’m a big believer in supplementing and not meal replacing!

It’s going to be interesting to see if this formula really does live up to its popular reputation.

Background on Protein World

Protein World was founded in 2013 by Arjun Sejun. Although Protein World was founded and is still based in the UK, the company provides customers worldwide in over 70 countries.

Although protein-based supplements are the brand’s most well-known and popular supplements, Protein World produces over 90 different supplements and products, from weight loss formulas and pancake mix to beauty capsules and multivitamins.

Slender Blend Benefits

Protein World claims that the Slender Blend formula will help you lose weight, tone up, help repair and rebuild muscle, promote a healthy gut, burn fat, and promote overall health and wellbeing.

The brand links specific types of ingredients within the formula to the benefits. For example, “[the formula will] promote a healthy gut – with high fiber content and added pre and probiotics”.

Slender Blend Ingredients

The Slender Blend formula has a wide range of ingredients and is available in either the standard version or a vegan version.

All of the ingredients, apart from the flavoring ingredients within this formula are fully disclosed, which is great to see.

So, let’s take a look at the ingredients list!

Here is the complete list of the Slender Blend ingredients:

  • Protein World Thermogenic Blend – Guarana Extract (22% caffeine) (100mg), Green Tea Extract (40% polyphenols) (100mg).
  • Protein World Digestive Enzyme Blend – Lactase (3500 ALU) (40mg), Protease (10,000 HUT/g) (25mg).

Here is the supplement facts label:

How does Slender Blend Taste?

Slender Blend is available in a wide range of flavors – Vanilla Ice Cream, Milk Chocolate, Cookies & Cream, Chocolate Mint, Strawberry Milkshake, Banana Split, Salted Caramel, White Chocolate & Raspberry, Peanut Butter, Fudge Sunday, Banoffee Pie, and Strawberries & Cream.

The vegan version of this formula is available in Vegan Vanilla, Vegan Chocolate, and Vegan Strawberries & Cream.

Looking at customer reviews, some people really enjoy the taste of the formula regardless of flavor, but some find the formula too sweet.

The people that find it too sweet are most likely referring to the fact that the formula contains sucralose, an artificial sweetener.

Unfortunately, sucralose has been linked to detrimental health effects such as inflammation and diabetes.

However, the vegan version is sweetened with stevia, which is a healthier alternative.

Side Effects

Protein World states that the formula contains allergens that are highlighted on the packaging in bold, and also states that anyone who is on medication, breastfeeding, or pregnant should consult a doctor before consuming this supplement.

I would just add that if you have a medical condition or you’re under 18 years old you should seek medical advice before consuming the formula.

Does Slender Blend Work?

The Slender Blend formula contains a number of essential vitamins, minerals, and a selection of other ingredients, with each ingredient being fully disclosed.

Due to the fact that the amounts of each ingredient are shown, the consumer knows what’s in the formula and what they’re consuming, and it makes working out the efficacy of the formula easy.

The formula definitely contains a substantial amount of protein, but the other ingredients are just missing the standard recommended doses.

This formula contains 23.2g of protein which is a substantial amount of protein for a supplement.

The recommended amount of protein per day is 0.36g per pound of body weight. Therefore, for the average man, this is 56g per day and for the average woman this works out at 46g per day.

Therefore, the amount of protein in this formula is nearly half of a man’s daily recommended protein amount. So, this is definitely a useful amount of protein to consume.

Looking at the other ingredients in the formula, they seem to just miss the recommended doses, at least for the ones that do have standard recommended doses.

For example, the recommended dose of green tea extract is 250-500mg, and the formula contains 100mg per serving of green tea extract, therefore just missing the recommended dose.

The recommended dose of guarana extract is 200-1600mg, and the formula contains 100mg per serving of guarana extract, therefore once again just missing the recommended dose.

My other issue is the fact that the brand uses sucralose to sweeten the formula, which can be detrimental to health, and the fact that there’s 7.8g of sugars per serving concerns me massively.

Overall, the formula definitely contains a substantial amount of protein, but the other ingredients are just missing the standard recommended doses and therefore may not provide the full range of benefits that they would if they were sufficiently dosed.

Slender Blend Reviews

Slender Blend is available on Amazon, and therefore we can take a look on there at unbiased customer reviews. Overall, the formula scores 4.3 stars out of 5 stars, from 844 customer reviews.

So, let’s take a look at a selection of these reviews.

Can never fault Protein world! I have already used their products and therefore this is everything I expected! Delicious taste, easy to use! Comes with the scoop and a good price! Already seeing results! 5-star reviewer

Product is fine, but doesn’t come with a scoop. So “add 4 yellow scoops” as a measurement doesn’t really work. 3-star reviewer

This is sickingly sweet! I really struggle to drink this, I’ve tried adding water instead of milk to try take the extreme sweetness off but it hasnt helped. I bought the vanilla flavour. Taste nice but the sweetness is just unbareable and this is coming from a sweet tooth!!! I would not buy again. 1-star reviewer

Money-Back Guarantee / Returns Policy

Protein World offers a 14-day money-back guarantee on all unopened products. This is rather disappointing considering many brands offer refunds on opened tubs!

Where to buy Slender Blend?

You can buy the formula from the Protein World website, from Amazon, and from stores such as Boots and Holland and Barratt in the UK.

Is It Worth The Price?

You can buy either a 1/2 month supply, a 1 month supply, or a 2 month supply of Slender Blend. You can also either sign up for a subscription or buy the product as a one-time purchase.

Obviously, if you sign up for a subscription, the price of the formula reduces.

To keep things simple, we’re going to take a look at the 1 monthly supply of Slender Blend, as most other supplements are sold in 1-month bundles.

On a one-time purchase, a 1 month supply of Slender Blend costs $69.99, which works out at a cost per serving of $2.33.

On a subscription, a 1 month supply of Slender Blend costs $29.99, which is a huge price reduction! On a subscription, the cost per serving of the formula goes down to $1.00.

Clearly, the subscription option is significantly cheaper, so if you know that you like the formula, it’s best to purchase it on a subscription!

The formula is fairly priced, in my opinion, due to the fact that it has a fully disclosed ingredients label and contains 23.2g of protein per serving.

However, I’m still concerned about the sucralose in the formula that could cause detrimental health benefits.

My Final Verdict

Personally, I know that I wouldn’t purchase this formula if I was looking for a protein and micronutrient supplement.

The main reasons why I don’t like the formula are that it has a high sugar content that contains sucralose, and some of the ingredients within the formula aren’t sufficiently dosed.

Although there are some great benefits to this formula, such as the wide range of flavors, the substantial serving of protein, and the popular customer reviews, I believe there are better, more natural protein supplements out there.

Therefore, I wouldn’t purchase this product and would instead choose to look elsewhere.

I would prefer to mix a more natural, sucralose-free protein powder with a super greens formula to reap more benefits from a singular drink.
