Flexoplex Review Overview
We recommend reading our full Flexoplex review before making a buying decision. We think Flexoplex is a complete rip-off. There really is no other way to say it. This joint supplement does give us a big dose of glucosamine and an almost excessively large serving of chondroitin. But Flexoplex also gives us a horrible, messy proprietary blend full of ineffective filler ingredients. We hate proprietary blends, and so should you. There is no good reason for the makers of this supplement to be using a prop blend here; they’re always just a sign of a rip-off – steer clear! There are better joint supplements than Flexoplex!
Flexoplex Review: Is this joint stack worth the hype?
Anyone researching joint supplements will inevitably come across Flexoplex sooner or later. This is easily one of the most popular joint and flexibility stacks in the world. People all over the US, Canada, Australia, the UK and EU all use Flexoplex for various reasons. So what does it claim to do exactly? Why is it so popular?
If you look at the bottle, you’ll see that Flexoplex claims the following benefits:
- Soothes, rebuilds and lubricates joints
- Relieves joint pain and reduces inflammation
- Supports healthy bones and joints
By the looks of it then, Flexoplex is supposed to be a complete joint support supplement.
The question is, does it really do all of this?
Does Flexoplex really work? Is it safe? Is it worth the money? Are there better options than Flexoplex on the market right now? Read our detailed Flexoplex review below and you’ll find answers to all these questions and more!

Proprietary blend warning
A significant portion of the Flexoplex formula is a proprietary blend. All tat means is that the manufacturer is refusing to tell us the exact serving sizes for those ingredients. This is highly unusual, and generally only occurs when you are being ripped off with cheap filler ingredients. We advise you to stay well away from proprietary blends.
We’ll now go through the Flexoplex ingredients one by one, telling you what they are supposed to do, what the scientific evidence says, and what we make of the doses. If you have any questions, please let us know in the comments section at the end.
Glucosamine sulfate sodium salt – 750mg
Glucosamine is found in the connective tissues that surround your joints, including your cartilage, ligaments, tendons, and even the synovial fluids. Supplementing with glucosamine has been shown to improve flexibility, reduce joint pain, and protect against wear-and-tear. Flexoplex provides 750mg of a highly bioavailable glucosamine salt, which is good.
Chondroitin sulfate – 600mg
Chondroitin is a very important substance for protecting your joints. It is actually a complex of molecules that suffuses the “web” which surrounds your cartilage. Its most important property is that it holds onto water molecules. Its ability to meld into cartilage and hold water allows it to carry out lots of important jobs: lubricating joints; absorbing impact; promoting cartilage production, and repairing cartilage when damaged.
The 600mg we get in Flexoplex is way more than we need to see results.
MSM – DOSE UNKNOWN
Methylsulfonylmethane is a vital nutrient for supporting proper joint maintenance. It is a structural component of collagen, glucosamine, and chondroitin. While supplementing with glucosamine and chondroitin is beneficial, it is a good idea to increase MSM consumption as well. Supplementing with collagen is completely useless; better to use a good quality MSM.
Cat’s claw bark powder – DOSE UNKNOWN
Cat’s claw is not a joint supplement. We have no idea why it is in Flexoplex. Cat’s claw does have some history of use as a cure for arthritis. It is said to have anti-inflammatory properties. We have never seen any good evidence that it actually works in practice. All of the clinical trials showing anti-inflammatory action with Cat’s claw were either done in test tubes or on animals!
Rutin – DOSE UNKNOWN
Rutin is a flavonoid – a plant pigment. It has some really interesting properties, from stimulating the immune system to helping your body produce collagen. However, we don’t like seeing this stuff in joint supplements. Rutin is found in very large quantities in apples, oranges, lemons, figs, and tea. You probably consume a lot every day as it is. We don’t know how much is in Flexoplex, but we doubt it’s enough to make any kind of difference to your flexibility.
Boswellia serrata – DOSE UNKNOWN
Boswellia serrata is one of the best natural joint supplements in existence. It works by inhibiting enzymes which break down important connective tissues, and by supporting your immune system’s response to joint damage.
But Boswellia serrata is only effective if you use enough of it. We don’t know how much is in Flexoplex. Considering how expensive it is – and the fact the manufacturer is hiding the dose – we bet there isn’t very much in Flexoplex at all. Otherwise they’d tell us!
Gum resin extract – DOSE UNKNOWN
We don’t know what gum resin they’re talking about here. It might be Boswellia serrata extract again, but probably not (because there’s no point listing the same ingredient twice). This is such a general ingredient we don’t even know how to analyse it properly. Of all the Flexoplex ingredients, this is the most suspect.
Hyaluronic acid – DOSE UNKNOWN
Hyaluronic acid is another substance found in large quantities in all of your connective tissues (as well as neural tissues). Supplementing with hyaluronic acid has been shown to significantly reduce joint pain in people with osteoarthritis.
However, to see benefits, you need to use enough hyaluronic acid for a prolonged period. We doubt you get more than a few milligrams in Flexoplex. If we got a decent dose you can be sure the manufacturer would brag about it!
Bromelain complex – DOSE UNKNOWN
Bromelain is an enzyme found in pineapples. Pineapples have a long history of use in traditional medicine for a variety of purposes, from reducing inflammation to soothing pain. There is some good clinical evidence that bromelain can reduce inflammation and soothe joint pain. But once again, dose is key. We don’t know how much bromelain we get in Flexoplex, and that’s a big issue.
Soy lecithin powder – DOSE UNKNOWN
The presence of soy lecithin is one of our main issues with Flexoplex’s formula. This stuff has its uses, but it isn’t a particularly effective supplement for reducing joint pain or promoting flexibility. More importantly, you can buy soy lecithin from every health food or supplement store for very little money – a bottle of 1200mg capsules will set you back about $15. We think the Flexoplex prop blend is stuffed full of soy lecithin.
Trypsin complex – DOSE UNKNOWN
Trypsin is an enzyme which helps further break down protein in the small intestine after it has been partially digested in the stomach. We have no idea why this stuff is in Flexoplex; it has no known effect on joint health or flexibility.
Boron aspartate – DOSE UNKNOWN
Boron is an essential nutrient for lots of different bodily functions, including joint function and long-term joint health. However, it isn’t particularly important for supporting healthy joints, and supplementing with boron is not thought to have a dramatic effect on your joints.
We don’t know how much boron is in Flexoplex, and that’s a BIG safety concern. Large quantities of boron can have serious adverse effects. We’ll discuss this more in the side effects section.
Formula analysis: Is Flexoplex any good?
We have absolutely no idea how there are so many positive Flexoplex reviews out there, or how it has managed to become such a popular joint supplement.
Flexoplex is a terrible joint stack.
Our main issue with it is the proprietary blend.
Proprietary blends are only ever used when the manufacturer is trying to hide a low-quality formula. There’s no other reason to use one; formula theft doesn’t happen. They aren’t hiding their special, unique formula – they’re just hiding the fact that 90% of the blend is made up of the cheapest, least effective ingredients.
Considering the number of cheap, useless ingredients in the Flexoplex proprietary blend, we think it is highly likely that this is happening here too.
The Flexoplex blend could be 99% soy lecithin powder for all we know. You can buy bottles of 1200mg capsules of this stuff for about $10.
Don’t fall for it – any proprietary blend is just there to hide how badly you’re being ripped off!
We also have a problem with some of the ingredients used in Flexoplex.
Cat’s claw lacks substantive scientific evidence, and as far as we know, it is not widely used to relieve joint pain or promote flexibility. It is one of those general health herbs that claims to do everything but in reality does nothing!
Boron is not particularly useful if your goal is flexibility and motility.
Same goes for Trypsin, which is an enzyme responsible for breaking down protein.
All-in-all, Flexoplex is a bit of a dud.
We don’t understand how Flexoplex has become such a popular joint supplement. There are far better options on the market right now for supporting joint health, promoting flexibility and protecting against wear and tear.
If you want good value for money, stay clear of rip-off proprietary blends like the one we find in Flexoplex!
Flexoplex Side Effects: Is it safe?
Flexoplex looks like a safe joint supplement on the whole.
The ingredients in Flexoplex are all pretty standard for a joint supplement; they are widely used in joint health products around the world.
More importantly, all of the Flexoplex ingredients have been thoroughly tested in clinical trials (although remember not all have been trialled as joint supplements). None have been found to cause serious side effects, and none are thought to pose long-term health risks.
That said, there is one major concern here – the boron aspartate.
We don’t know how much boron is in each serving of Flexoplex, and that’s a big issue. Consuming sizable quantities of boron on a regular basis will cause serious side effects, including:
Consuming large doses of boron can have much more serious effects, including:
Basically, you should know how much boron you are taking each day to control it. The fact that Flexoplex hides the boron dose shows us that they either don’t know a thing about nutrition, or they don’t care about your well-being.
Remember, everyone is different. You have your own unique allergies, medical history, and so on.
It is important that you read the Flexoplex ingredients list carefully and talk to a health professional if you have any concerns at all.
If you have severe and chronic joint pain, then you need proper medical attention, not a supplement.
CAUTION – Disclaimer
It is vital that you talk to a qualified health professional before you start using Flexoplex, or any other joint supplement for that matter. You must do your own research properly before using any new supplements, even if they look safe to us. We are not doctors. This is not medical advice.
Flexoplex Review Conclusion: Is it good for joint pain and flexibility?
We would not recommend Flexoplex to anybody, regardless of their particular needs. We don’t think it is a good joint supplement, and we certainly don’t think it is better than some similar products on the market today.
The big problem with Flexoplex is the proprietary blend. As we explained above, prop blends are always a sign that you’re being ripped off. There’s simply no good reason for a manufacturer to use one – all of the best joint supplements show their full formulas on the bottle, and they don’t get copied.
It just doesn’t happen.
The reason Flexoplex lumps a lot of its ingredients together into a proprietary blend is almost definitely so the manufacturer can cut back on the most expensive ingredients.
For all we know, 99% of the prop blend could be soy lecithin powder (which you can buy in bulk for very little money).
Many of the ingredients in Flexoplex do absolutely nothing for joint health or flexibility anyway.
All-in-all, this is a pretty terrible option for anyone looking to maximize joint health, reduce pain, and promote flexibility.
There are far better supplement on the market today for improving flexibility and reducing joint pain naturally. Don’t waste your money on cheap garbage like Flexoplex.
