Plexus Boost Review

Plexus Boost Facts

  • Plexus Boost is produced by MLM company Plexus Worldwide
  • You are encouraged to join the company as an ambassador and sell the supplement range yourself
  • The supplement lacks a full ingredients profile

Plexus Boost is a diet pill that the makers claim will “energise your life”.

It contains a range of ingredients including Yerba Mate and Green Tea Extract, which will provide the stimulant firepower as well as cactus Caralluma Fimbriata that may act to suppress your appetite. In addition, it contains some vitamins and minerals as well.

Although the ingredient quantities are not provided – the herbal ingredients are part of a proprietary blend – with 900mg of this per serving, there should be enough to cause an effect.

According to the advertising, you can use Plexus Boost in combination with Plexus Slim – a supplement in the form of a shake, which you drink 30 minutes before meals. Alternatively, you can use Plexus Boost as a standalone product or combine it with others in the Plexus range.

How to Take Plexus Boost

To take Plexus Boost, you are advised to use 1-2 capsules. Presumably, this is the daily amount but the website information does not make this very clear.

Plexus Boost is made by Plexus Worldwide Inc.

The company head quarters is
Plexus Worldwide Inc.
15649 N. Greenway Hayden Loop
Scottsdale, AZ 85260

The Plexus range is sold via network marketing. Plexus sellers – called ambassadors can sign up to market the supplements to their friends and family and actively seek customers via Facebook or other means.

Will you get rich if you become a Plexus Ambassador? Probably not but if you like the supplements and fancy the idea of some extra cash, it may appeal to you.

Plexus Boost Concerns:

  • Taken long term this supplement could be potentially dangerous
  • Higenamine may have unpredictable side effects
  • We were unable to find any unbiased feedback for this supplement

What Does Plexus Boost Claim To Do?

The advertising claims that Plexus Boost is “formulated to energise your life”.

It contains a “thermogenic blend” of ingredients plus Caralluma Fimbriata an edible cactus that;

has been traditionally used by tribal East Indians for years to suppress hunger and enhance endurance through increased energy

According to Plexus, this;

has now been clinically proven to suppress appetite, reduce body weight and increase energy intake

We would not go as far as describing Caralluma as being clinically proven. The preliminary testing has looked positive but the scientific opinion is that it requires further clinical testing and evidence.

We covered Caralluma in a previous review and thought it looked promising.

Plexus Boost is sure to live up to its name, helping deliver the weight loss results you want and the energy you need.

This sounds good but we would have liked to have seen some proof and some links to the relevant clinical testing.

So What Is Plexus Boost and What Are The Ingredients For Plexus Boost?

Plexus Boost is a fat burning diet pill combined with an appetite suppressant.

Each capsule is equal to one serving.

  • Calcium Glycinate (50mg): Easily absorbable form of calcium – the most abundant mineral in the body and necessary for healthy bones and teeth. Calcium also plays an important role in cardio health. The RDA is around 1000mg for adults, most of which is obtainable by diet. For example, there is approximately 307mg in 1.5 oz of cheese.
  • Vitamin B6 (30mg): This vitamin is involved in many aspects of the metabolism and enables the body to use and store energy. It is vital for the breakdown of lipids. Vitamin B6 is present in many foodstuffs including pork, bread, eggs, fish and poultry.. The NHS advise that the recommended adult daily intake of vitamin B6 is 1.4mg a day for men and 1.2mg a day for women so this is way in excess of this figure and may cause side effects. When taken to excess it can cause skin irritation
  • Niacin (20mg): Also known as vitamin B3, this vitamin is important for heart health. The RDA is 35mg for adults and when taken in high quantities it can cause facial redness and itching although this is not dangerous.
  • Chromium Picolinate (1.5mg): This trace mineral is believed to help reduce carb cravings but there is no real evidence that it does. At high levels, Chromium can be dangerous for health but here in low and safe quantities.
  • Vitamin B12 (500mcg): This vitamin helps in the production of healthy red blood cells that carry oxygen around the body and deficiency can cause fatigue and anaemia. A healthy diet should deliver sufficient B12 without the need for supplementation.
  • Folic Acid (400mcg): This water-soluble B vitamin is important for pregnant women because it helps protect against birth defects. It is also used to prevent heart disease and strokes so is necessary in later life too. However, folic acid supplementation can interact with medication for depression.

Proprietary Blend 900mg

  • Caralluma Fimbriata Extract: Succulent Asian plant, which has appetite-suppressing qualities and has performed well in clinical testing. Although results are promising, it is requires further testing and the effective dose for weight loss has yet to be identified. We looked at this ingredient in more detail in our Caralluma Fibriata article
  • Citrus Reticulata (Mandarin orange) / Nelumbo nucifera (lotus) Blend Higenamine from tangerine peel / lotus seed/: Higenamine is a stimulant chemical compound found in many plants including oranges lotus seed and poisonous plant aconite. A variety of effects have been observed in lab studies and via animal testing. It has no relevance to weight loss and is known to increase the heart rate. It is potentially dangerous.
    Source: WebMD resource
  • Yerba Mate: Extract Natural herbal extract taken from a South American plant. May be effective for weight loss and contains high levels of flavanoids and antioxidants. Contains high levels of caffeine.
  • Green Tea extract: With proven health benefits because of its high levels of antioxidants, green tea has been found to promote modest weight loss. It can help increase the speed the metabolism. Contains caffeine

So What Does All This Mean?

Plexus Boost contains some questionable ingredients in unknown amounts. For starters, the vitamin B6 content is high and in way excess of the RDA, which could cause skin irritation.

However, we are more concerned about the Higenamine content because it is known to raise heart rate and medical advice is NOT to take this supplement ingredient. It can cause dangerous heart related side effects.
We feel that the Plexus information should have alerted customers to this effect.

There could be high quantities of the other stimulants too– Yerba Mata contains more caffeine than coffee for example and at 900mg a serving, this is a high dose. Again, there should have been a warning because this will not suit everyone.

The Green Tea extract looks good and Caralluma Fimbriata does look promising so this could help you lose some weight but there are health concerns.

Plexus Boost looks strong and we certainly would not recommend you to take it long term as the Plexus Preferred Customer option, an auto billing agreement, recommends.

Does Plexus Boost Have Any Side Effects?

We cannot bring you any true-life experiences so only have the ingredients list to go on.

Potential side effects include;

  • Jitteriness
  • Anxiety
  • Insomnia
  • Nausea
  • Headache
  • Ringing in ears
  • Itchiness
  • Increased heart rate
  • Irregular heart beat
  • High blood pressure
  • Increase risk of stroke or heart attack


Avoid if you are pregnant or breast-feeding. Do not take if you suffer from a heart related medical condition or have high blood pressure.

Avoid if you are sensitive to stimulants including caffeine. Seek the advice of your doctor before taking this supplement, especially if you have an underlying health condition.

Medical opinion is NOT to take Higenamine in supplement form so it is probably safer to avoid taking this supplement. If you do take it, discontinue use if you experience side effects and seek the advice of your doctor.

Any Plexus Boost Reviews From Customers?

Because so many people are trying to sell Plexus Boost, it is impossible to find unbiased feedback.

There are a few reviews on but the Plexus Ambassadors have been quick to praise the supplement and to promote their own sales pages.

One customer cleverly got the link to his or her website via the review title.

AWESOME PRODUCT – [link removed]
Helps you lose the weight fast with no jitters!

Another person with her name followed by myplexusproducts said;

Boost is awesome!


Although these prices on AMAZON are Way more than MSRP…I love Plexus Slim. I have lost over 40 lbs! It is great for Diabetic or those who struggle with weight loss. It is designed to work without diet or exercise. I use the Plexus Slim, Boost, BioCleanse, and ProBio5. I have natural energy without any jittery side effects! Anyone can get wholesale prices…

This reviewer goes onto post a link to her own site that promotes the supplement. We fail to understand how you can have “natural energy” after taking stimulants.

So Does Plexus Boost Work?

Plexus Boost may act as a stimulant and this may give you more energy as well as make you feel too on edge to eat.
The Caralluma Fimbriata may add to this appetite suppressing effect too if the preliminary clinical testing is anything to go by.

Caffeine and green tea in combination may help weight loss through thermogenesis and fat oxidation. However if you are a high caffeine user you may notice any difference.

In a trial carried out on 76 people it was found that green tea-caffeine mixture improved weight management for habitual low caffeine consumers through thermogenesis and fat oxidation.

In the high caffeine consumers, no effects of the green tea-caffeine mixture were observed.


However, the major concern is with Higenamine. This is a constituent of the plant Aconite which has been well known throughout history as a poison.

In ancient Rome, high doses of Aconite powder were commonly used to poison unwanted enemies, who then died of a ‘sudden and unexpected heart attack’

Higenamine lacks clinical testing for safety and the medical advice to avoid this ingredient.


Where Can I Buy Plexus Boost?

If you want to try Plexus Boost, you have to go through an ambassador in your local area via the website or call Plexus in order to find one for you.

There are three ways of buying. You can become a “Preferred Customer” – a fancy name for signing up to auto billing where you get sent new supplies each month. Alternatively, you can simply buy Plexus Boost by using a one off payment. The third way is to sign up as an Ambassador yourself.

One bottle of 60 capsules (one month’s supply) costs $39.00. You will need to ask your Ambassador about shipping costs. If you are a Preferred Customer one 60 capsule bottle of Plexus Boosts costs $29.00.

Plexus Boost is also on sale via A bottle of 60 capsules costs $49.00 plus $4.99 shipping to US address.

The Amazon option, as the reviewers pointed out, is more expensive. But it seems a lot more straightforward!

Caution: When signing up for any “auto-billing” (or “preferred customer” plan as Plexus call it) be aware of the monthly costs and the cancellation policy. We are not fans of this payment method as they can be difficult to cancel, depending on the company.

What About A Guarantee

Plexus products all come with a 60 guarantee, which looks good. However, you will have to buy via a Plexus Ambassador in order to qualify. If you are an Ambassador yourself, the company will honour the guarantee on your behalf.

We have not come across any complaints relating to the Plexus guarantee.

Watchdog Verdict

Plexus Boost may help you lose a little weight if you are not a heavy caffeine user already and the Caralluma Fimbriata may have an appetite reducing effect. However, we are extremely concerned about the Higenamine content.

This stimulant lacks clinical testing and is potentially unsafe. It does not seem to be relevant to losing weight and medical opinion is to avoid this ingredient. Therefore, it seems really irresponsible to add this to a diet pill and then not post any warnings.

In addition, Plexus encourage you to sign up to an auto ship program and take the supplement on a permanent basis. We never recommend you should take supplements long term – especially those which contain potentially dangerous ingredients, let although the impact on your wallet.

That said we like the guarantee and although we are not big fans of direct marketing we understand that everyone needs a dream. However if you are thinking about doing this yourself it might be worth considering that nobody appears to have bought Plexus Boost via This suggests that this supplement is just not very popular on the open market and cannot stand alone without a persuasive and personal sales pitch.

In our opinion, Plexus Boost is just not safe enough or good enough to add to our approved list so we have no other choice but to reject it.

    Before “Boost”, there was “Accelerator Plus”. Before that, there was “Accelerator”. Before that, all you had to take was Plexus Slim. Every time this sham company rolls out a new product, the “ambassadors” are coached to push the product as an answer to why all the other stuff ain’t working. If the Plexus Slim shake isn’t giving you results, well you need the Boost, Bio-Cleanse, and Pro-Bio in order to get the full effect. Now they come out with a carb-blocker product called “Block”. That’s now billed as the latest and greatest. The only problem is that carb blockers do not work and further, are harmful to diabetics, which this company markets directly to. Make no mistake about it, this company is in the business of making money. They do not test their products, they do not disclose where their products are manufactured. Who knows what it truly is?

    I like the slim but the boost makes my heart race. I started with one then went to two. Twice my heart started racing and pounding. Pulse was 134. So I’m off the boost.
