Flexitrinol Review Summary
Flexitrinol is a complete rip-off. We cannot believe how over-priced this joint supplement is; $80 for a single bottle of what could be just three ingredients (one of which is almost entirely Evening Primrose Oil)! While some of the ingredients in Flexitrinol do help with joint pain and stiffness, there isn’t anywhere near enough here to really deliver meaningful beenfits. There’s certainly not enough to justify the HUGE price tag. If you are looking for a supplement to help ease joint pain naturally, or to protect your joints from damage as you get older, this is not for you! Much better joint supplements are available, and they’re cheaper too!
Flexitrinol Review: Does this joint supplement really work?
Flexitrinol is one of the best-selling joint supplements on the market today. Made by a company called “Health Research Institute”, Flexitrinol is described as an exciting new joint supplement designed to provide relief for people with swollen, painful joints, as well as support for the generation of new cartilage.
According to the website, Flexitrinol is ideal for anyone wanting to reduce joint pain and increase range of motion, as it delivers the following key benefits:
- Improves joint strength
- Reduces joint pain
- Lubricates joints and increases renage of motion
- reduces inflammation
Worryingly, Health Research Institute (which isn’t a research institute at all) describes Flexitrinol as a “doctor formulated” joint supplement. The company has a history of fabricating claims about “doctor recommendations” – more on this later!
Does Flexitrinol really work? Is it safe? Is it effective for joint pain relief and long-term joint health? Is it the best joint supplement on the market for reducing inflammation and promoting cartilage growth? Read our detailed Flexitrinol review below to find out!
Flexitrinol Ingredients
What is in Flexitrinol? This is the most important question that Flexitrinol reviews need to answer, as it is the cinstituents of a supplement that make it what it is.
Here is the Flexitrinol ingredients list as it appears on the bottle:
In case that image isn’t clear, here is a list of the Flexitrinol ingredients along with dosages:
- Glucosamine HCL – 500mg
- JointFlex Proprietary Blend – 200mg
- MSM
- Chondroitin sulfate
- Omega 3-6-9 Proprietary Blend – 90mg
- Flaxseed oil
- Evening primrose oil
- Fish oil
Right off the bat we can say that we do not like the Flexitrinol formula at all. There are so many problems here that we don’t even know where to start. Proprietary blends are always a big RED FLAG, as they’re only used to hide shoddy ingredients and low doses. The ingredients themselves are hardly good quality! More on this later.
We’ll now go through the Flexitrinol ingreidents one by one, explaining in each case what they do (or don’t do), what the scientific evidence has to say, and what we make of the dosage. Then we’ll discuss the Flexitrinol formula as a whole.
Glucosamine HCL – 500mg
Glucosamine is an amino sugar which is found naturally in the tissues and fluids which surround the joints, including cartilage, the ligaments, and the synovial fluid which cushions and lubricates the joints. Clinical studies suggest that increasing the availability of glucosamine will increase the synthesis of these tissues. As the degradation of these tissues is known to cause joint pain, supporting the formation and maintenance of these tissues is likely to reduce joint pain in some cases, as well as promote strong, healthy, flexible joints going forward.
Flexitrinol contains 500mg of glucosamine HCL. This is a good dose of a highly bioavailable form of glucosamine. Clinical studies show that 500mg of glucosamine daily can effectively reduce joint pain and provide good joint support over the long-term. however, for optimal results we strongly recommend using glucosamine sulfate (as the most bioavailable form of the joint supplement).
MSM – DOSE UNKNOWN
Most good joint supplements today will contain some MSM (Methylsulfonylmethane). MSM is a naturally occurring substance found in abundance in joint tissues. MSM is necessary for the formation of collagen, chondroitin, glucosamine, and other substances which together combine to form joint tissues like cartilage and the ligaments. Clinical studies show that MSM supplementation may improve joint flexibility, provide pain relief from achy joints, and improve joint health generally. In particular, MSM supplements seem to be effective for reducing knee pain, especially that related to knee osteoarthritis (although MSM cannot cure or prevent knee osteoarthritis).
Flexitrinol contains an unknown quantity of MSM. All we know from the ingredients list is that MSM is in the “proprietary blend” at that said blend is 200mg in total size. This is a serious issue. We need to know the doses of the ingredients we’re taking to assess the potency of the stack! There could be 100mg of MSM in Flexitrinol, or there could be 1mg – there’s no way to know! One dose would be great for your joints, the other would do nothing for flexibility or joint pain.
Chondroitin sulfate – DOSE UNKNOWN
Chondroitin is a molecule chain made up of sugars. This large, complex molecule is found naturally weaved throughout the extracellular matrix of your cartilage. Because of its structure and composition, chondroitin naturally has a strong negative charge. This means chondroitin readily attracts and binds to water.
These properties mean that chondroitin actually helps your joints in a number of ways. Firstly, by absorbing water, chondroitin helps keep your joints lubricated and abl to absorb shocks and impacts. Secondly, chondroitin assists with the synthesis of collagen; a protein vital to strong, healthy, flexible joints. Finally, clinical studies show that chondroitin regulates the production of chondrocyte cells, which are responsible for controllin cartilage growth and repair.
Chondroitin is often one of the best ingredients in joint supplements. As it has some of the strongest scientific backing among all joint supplement ingredients, good products tend to dose it well. But Flexitrinol doesn’t tell us how much we get of this important ingredient.
Flaxseed oil – DOSE UNKNOWN
Flaxseed oil is not something you find on the ingredients list of many joint supplements. However, it is not necessarily a useless ingredient in Flexitrinol. Flaxssed oil has many benefits which would improve joint health, improve joint flexibility and ease joint pain. For starters, flaxseed oil is a potent anti-inflammatory. As a rich source of omega 3 fatty acids, flaxseed oil reduces inflammation which would in turn ease any joint pain caused by inflammation (e.g. rheumatoid arthritis, tennis elbow, etc).
However, there’s a big problem here. We don’t know the exact quantity of flaxseed oil in Flexitrinol. What we do klnow is that it must be less than or nearly equal to 90mg, as this is the total size of the Flexitrinol omega 3 fatty acid blend. This is a pathetic dose for any one of these oils; let alone the total dose ofr all three! Most flaxseed oil supplements use 1000mg capsules – ten times the amount you may get from Flexitrinol! Then there’s the fact that Flaxseed oil is not even the best source of omega 3 fatty acids!
Evening primrose oil – DOSE UNKNOWN
There is absolutely no reason why Evening Primrose oil is in a joint supplement like Flexitrinol. If Health Research Institute wanted to include some good omega 3 fatty acids in Flexitrinol, then the obvious choices are fish oil, flaxseed oil, or better still, algae oil. Evening primrose oil is not particularly rich in anti-inflammatory omega 3 fatty acids. What it does contain is a sizeable amount of omega 6 and 9 fatty acids. These are pro-inflammatory fatty acids which would make inflammation and related joint pain much worse!
Fish oil – DOSE UNKNOWN
Fish oil is a good source of omega 3 fatty acids (as well as being loaded with harmful heavy metals). As discussed, taking omega 3 fatty acids is a good way to ease joint pain, reduce inflammation and support overall good health. However, Flexitrinol doesn’t contain anywhere near enough fish oil, or any oil, to deliver these benefits.
The maximum amount of fish oil there could be in Flexitrinol is 90mg. The best omega 3 supplement on the market today, an algae oil, contains 2000mg of pure algae oil, 1100mg of which is omega 3 fatty acids. Does the 90mg oil blend in Flexitrinol sound like it can deliver the same joint pain soothing, anti-inflammatory benefits as 1100mg of pure omega 3 fatty acids? Our suspicion is that Flexitrinol’s oil blend is mostly just Evening Primrose Oil, which is pro-inflammatory!
Formula analysis: Is Flexitrinol a good joint supplement?
We don’t see the need to pull any punches here – Flexitrinol is a TERRIBLE joint supplement.
The Flexitrinol formula is full of problems. The main issue with the Flexitrinol ingredients list is the lack of ingredient dosages in some cases. Rather than telling us exactly how much of each ingredient we get in Flexitrinol, Health Research Institute just fobs us off with proprietary blends.
Proprietary blends are always a red flag. Supplement manufacturers oly ever use them to hide low quality formulas or outright scams. The best joint supplements on sale today all show their ingredients and dosages in full; when a stack doesn’t, you know they’re hiding something.
We suspect what Flexitrinol is hiding is the fact that the supplement is mostly just Evening Primrose Oil, Chondroitin, and Glucosamine.
Chondroitin and Glucosamine are good joint supplements. But two basic forms of these ingredients does not make a comprehensive joint pain supplement. The best joint supplements on sale right now combine 3-6 potent, proven ingredients with different benefits to care for the joint as a whole.
As discussed above, Evening Primrose Oil does absolutely NOTHING for joint pain or flexibility.
Even if the oil prop blend was mostly fish oil or flaxseed oil, it would still be a pathetically small dose – too low to achieve anything.
On the whole then, Flexitrinol looks like a total rip-off to us!
If you’re suffering with joint pain, then it’s important to talk to a qualified health professional such as your regular doctor to find out if you have a serious underlying health issue. We can tell you that Flexitrinol is NOT DOCTOR FORMULATED as Health Research Institute fraudulently claim. It is an ineffective joint supplement and massively over-priced.
If you want to improve flexibility, ease joint pain naturally, and promote healthy joints and connective tissues over the long-term, then don’t waste your money on Flexitrinol. Better joint supplements are available. We strongly advise chekcing out our current rankings of the best joint supplements. We review dozens of joint products and help you find the ones that really delover without breaking the bank.
Flexitrinol Side Effects: Is it safe?
Is Flexitrinol safe?
Any Flexitrinol review needs to answer this question in detail.
The main side effect risk with Flexitrinol comes from the fact that we don’t know the dose of each ingredient. Health Research Institute has decided to keep the ingredient doses in some cases a secret, which means we can’t accurately judge side effet risks.
On the whole though, there are no ingredients in Flexitrinol known to cause serious side effects or adverse health consequences at reasonable doses. We do know the maximum possible doses for the ingredients in Flexitrinol and these doses are withion the ranges used in clinical trials.
So for most users, Flexitrinol should be safe. Side effects should be rare and mild. No clinical trials looking at the use of Flexitrinol’s ingredients by humans reported significant side effects at these (possible) doses.
Flexitrinol Reviews by Users: What are people saying about this joint pain supplement?
Below is a selection of Flexitrinol reviews from real users taken from the internet. While user reviews are far from the most helpful way to judge a supplement, they can give us an idea of whether we’re dealing with a complete scam or not.
How much does Flexitrinol cost?
How much does Flexitrinol cost?
A lot!
A single bottle of Flexitrinol costs $79.98. That is a ridiculously large price tag for a supplement that may well be just three ingredients, one of which is Evening Primrose Oil.
Compared to even the top-tier joint supplements on sale today, this is extremely expensive. The best natural joint pain supplement on the market right now costs around $40 a bottle, and it contains more, higher quality ingreidents than you get from Flexitrinol.
There is a Flexitrinol money back guarantee, but why loan this company your money as you’re inevitably going to return it?
Flexitrinol Review Summary: Is it worth the money?
Should you buy Flexitrinol? Is it worth the money? Is Flexitrinol effective for joint pain? Can it help build cartilage naturally?
Unfortunately, we think the answer to all of these questions is “no”.
We do not think Flexitrinol is good joint supplement at all.
It doesn’t matter how you look at it; value for money, ingredient quality, effectiveness – Flexitrinol looks like a terrible joint supplement on every measure.
The proprietary blends are a dead giveaway that Flexitrinol is over-priced. The best-selling joint supplements on the market all show their ingredients and dosages clearly on the label. Why hide Flexitrinol’s dosages? Clearly, you’re being ripped off.
The 90mg oil blend is the worst thing in the formula: 90mg split between fish oil, evening primrose oil, and flaxseed oil. That is a pathetically small dose for fish oil alone, and evening primrose oil has no benefits for joint health at all!
If you want help easing joint pain naturally, use a high quality joint supplement from a reputable manufacturer. Avoid all this “doctor formulated” garbage; it’s always a scam and it never offers the kind of joint pain relief or joint health support it claims!
