What You Need To Know About Plexus Block

Plexus Block like all the other Plexus supplements is expensive. Yes, you can buy in wholesale or through an ambassador but is this supplement really worth the bother of doing this? There are plenty of carb blockers on the market that will probably work just as well as this one and at a much cheaper price.

Alternatively, you could make some dietary changes and include more beans in your diet for the same effect.

Our Verdict On Plexus Block

When it comes to results – the name is misleading. Plexus Block will not block the absorption of anywhere near 48% of carbs and sugars as implied by the advertising.

In fact there is not a supplement in the world that will block almost 50% of what you eat and if you believe this it is likely you will put on weight, not lose it.

We are not impressed with Plexus Block so have no other option but to reject it.

Among the best products we’ve seen in 2016 is one called Phentaslim. Whilst not just containing clinically proven ingredients that have been shown to shift the fat, Phentaslim is very unlikely to give you unwanted side effects.

The makers of Phentaslim are so confident in their product they offer a no-risk 60-day money back guarantee too. To find out why this is our visitors #1 choice in our review here.

Plexus Block Review

Plexus Block is a carb blocker, which means that it is supposed to block some of the carbs that you eat from being absorbed by your body. Instead, they are just passed through your system in the usual way and not added to fat.

Plexus Block Facts

  • Contains a branded supplement called InSea
  • Claims to block 48% of dietary fats from being absorbed by your body
  • Often causes gas and other embarrassing side effects

The supplement contains white kidney bean extract and brown seaweed extract as the carb blocking ingredients and there is trace mineral chromium believed to help manage glucose levels.

How to Take Plexus Block

Take 2 capsules before a meal, which contains sugars or carbohydrates.

Plexus Block is just one in a wide product range from Plexus Worldwide, a well-known American Multi Level Marketing company. This means that if you like the products you can sell them yourself as a Plexus Ambassador. Some people claim they have quit their jobs in order to sell Plexus products full time.

Plexus Block Concerns:

  • You may actually put on weight if you believe you can eat without it adding to body fat
  • No real evidence to prove that this supplement will block fat
  • Is Plexus Worldwide a direct marketing company or a pyramid scam? It is hard to find any independent customers

Other Plexus products include Plexus Bio Cleanse, Plexus ProBio5 and the flagship supplement – the Pink Drink also known as Plexus Slim.

What Does Plexus Block Claim To Do?

According to the product advertising, Plexus Block:

  • Neutralizes enzymes that convert carbohydrates into glucose
  • Neutralizes enzymes that convert sugar into glucose
  • Helps improve glucose metabolism

Does Plexus Block Work?

White Kidney Bean extract is rich in fibre and can cause feelings of fullness and it seems to block the absorption of carbs although strength of the effect is unknown.

The other two ingredients – brown seaweed extract and chromium are supposed to reduce starch absorption and regulate blood sugar levels.

The problem with any kind of carb blocker is that many of feel that it gives us a license to over eat in the belief that the carbs and sugars will not add to our weight. If you believe that 48% of your dietary intake doesn’t matter, you could easily put on weight while you are using this supplement.

In addition, Plexus have manipulated figures because there is no evidence anywhere which says that 48% of the carbs that you eat will pass through your body as waste.

This supplement may block some carbs and sugars but the size of the effect may be very small. You may not even notice it. Source:

What Are The Ingredients of Plexus Block?

Each serving is equal to 2 capsules.

  • Chromax (200mcg): Branded chromium supplement from US company Nutrition 21. Some clinical testing has evaluated a lack of chromium as being the cause of an inability to process sugar properly and it has been researched for treatment and the management of diabetes.
    However, medical research has never found a biomedical reason for the body’s need for chromium.
    If you are diabetic, it is important to see your doctor before taking Chromax because it can interact with your medication.
  • InSea2 (500mg): This brown seaweed supplement from Canadian company Innovactiv has undergone clinical testing and is only available to the supplements industry.
    A clinical trial saw 23 participants given 2 slices of white bread 30 minutes after taking 500mg of InSea2 or a placebo. Blood sugar levels and insulin were tested 3 hours later and indicated 48% reduction in blood sugars in the control group. There have been 4 small clinical tests on InSea2 and results look promising
  • White Kidney Bean Extract (200mg): The only ingredient NOT a branded supplement and a good source of protein and fibre that can help you feel fuller for longer. Best used as part of a diet rather than in supplement form

Are There Any Customer Reviews For Plexus Block?

One of the problems with of reviewing supplements sold via Network Marketing, is that the Ambassadors are always quick to praise and advertise the products they are hoping to sell.

As this customer complained

… The other reviewers who all seem to be ambassadors who are only promoting themselves and not the product itself.
Reviews are supposed to be for honest, unbiased reviews of a product, not for advertising purposes. I would have loved to have seen reviews from someone not affiliated with Plexus on this product…

We agree wholeheartedly with this comment.

Here’s what one Plexus Ambassador wrote,

All Plexus products are amazing. Yes, I’m an ambassador with Plexus Worldwide and a Plexus user! I’m NOT trying to make a sale, but rather spread the word about these life changing products!

Another wrote,

Block is great to have on hand through the holidays and for treat meals. I take two capsules before a large meal and it helps me to not feel bloated and keep the weight off. I love it. I now save 40% by buying wholesale.
