I’ve always made sure to take multivitamins on a daily basis, but I’ve been guilty of disregarding my joint health while traveling the world.
I often stop off at regular locations to play soccer and rugby with my friends and didn’t really take into account what to do when my joints started aching after a while.
That’s when I was introduced to joint supplements in general. Read my Performance Lab Flex Review to find out more…
What Makes Performance Lab Flex Worth Trying?
One look through its ingredients and you see that no cost has been spared on producing this joint supplement. Countless studies have shown the effectiveness of such ingredients as Glucosamine, Turmeric, Chondroitin and MSM in improving your joint health.
We’ll get into the details of each ingredient in the next section, but the ingredients that make up Performance Lab Flex’s formula certainly convinced us to try it out in the first place.
Why? Because there are many supplements out there that are filled with ineffective ingredients. That’s a fact.
I also saw that Performance Lab offer a 30 day money back guarantee, making all risk of not liking the product disappear.
Apart from all the above, there’s not much more to say.
Remember that no supplement is a miracle pill that will magically fix a seriously bad knee that can’t be fixed by surgery. However, taking ingredients such as Glucosamine daily can help ensure that you’re giving yourself the best chance of protecting your joints.
Whether you’re very active like me and run 5k every weekend or are simply getting older and want to protect your joint health, including a joint supplement in your lifestyle is certainly a good option, in our honest opinion.
Performance Lab Flex Ingredients
I’ve already mentioned that the ingredients contained in this joint support supplement are what convinced me to try it out. It’s often rare to see a supplement that contains only clinically proven, effective ingredients, so it really is refreshing to see.
However, I won’t just repeat myself in this section. Instead, for those more interested in the details, I’ll go through and analyse each ingredient so that you know exactly what’s in Performance Lab Flex’s formula.
While Glucosamine may be one of the more “unknown” ingredients if you’ve not researched into joint support before, it’s certainly a key player that you should always look for.
This is because it is naturally present in your body in cartilage, ligaments and tendons. All things that are important to ease of movement in your body and surround your joints.
In effect, taking Glucosamine in supplement form allows you to keep your joints lubricated – like keeping mechanical parts oiled so they move easier and don’t go rusty.
Not only that, studies have found Glucosamine to be beneficial for other reasons too; one study found that daily Glucosamine use was linked with lower rates of cardiovascular disease too .
Glucosamine is also clinically proven to be even more effective when taken alongside Chondroitin (which is also included in Performance Lab Flex).
Picking up where we left off just above, we’re very happy to see the inclusion of Chondroitin. It shows that Performance Lab really do conduct in-depth research when formulating their products.
Here’s why: several studies have shown that Chondroitin taken with Glucosamine results in a significant reduction in joint space narrowing and pain . Especially those with knee osteoarthritis.
That’s not the only source. Another study concluded that Chondroitin and Glucosamine taken together was much more effective in relieving pain and improving physical function than placebo too .
If you’re interested, the reasons why Chondroitin is effective is due to it acting as a “shock absorber” like suspensions on a car by keeping your cartilage and joints optimally lubricated.
Even if you haven’t researched into supplements, everyone knows that Turmeric is beneficial.
It’s widely known for possessing high levels of the antioxidant, curcumin. It’s curcumin that’s shown to support joint health in clinical studies, with one study even concluding that supplementing with curcumin was equally as effective as using painkillers in terms of joint pain and physical function .
Of course, taking Turmeric in joint supplements is much better than using painkillers since Turmeric is completely natural and doesn’t cause side effects like chemicals in painkillers do.
All in all, another great addition to joint supplements and one we always look for when choosing a product.
Methylsulfonylmethane is often known as “MSM” and is naturally found in humans, animals and plants.
It’s a key addition to all joint support supplements due to its ability to slow the breakdown of cartilage, therefore providing protecting for your joints.
One interesting study which proves its effectiveness was conducted in 2017. This study used subjects running a half-marathon and provided them with MSM supplementation, with the results finding that it was able to help muscles recover and reduce joint pain after the half-marathon run .
Another study in 2006 proves MSM’s effectiveness; it concluded with stating MSm was able to improve symptoms of pain and physical function without any causing any side effects .
For all these reasons, MSM remains an ingredient we always look for in joint support supplements we choose to take too.
Traditionally used in Eastern medicine for centuries, the gum resin of the Boswellia Serrata tree is what’s used here. It’s been used to treat osteoarthritis, joint pain, rheumatoid arthritis for equally as long.
It works due to being an antiinflammatory agent, with recent clinical studies showing its effectiveness at providing joint support too by reducing the frequency of knee joint swelling compared to placebo .
While it’s not as important as Glucosamine and Chondroitin in joint support supplements (since it’s not as clinically proven in as many studies), it certainly isn’t a pointless filler ingredient either.
Strontium functions similar to Calcium in that it affects how your body makes new bone while slowing the breakdown of old bone.
More importantly for joint support, Strontium was found to help reduce joint space width and improve knee pain too.
However, we’d by lying if we said you wouldn’t find this in most multivitamin supplements. In fact, the multivitamin we currently take contains Strontium.
For this reason, while Strontium is clearly a beneficial ingredient (and by no means a pointless “filler” ingredient).
How to Take Performance Lab Flex
It’s recommended to take 2 capsules daily of Performance Lab Flex, with the whole bottle offering a 30 day supply.
We usually take Performance Lab Flex in the morning with our multivitamin so that we don’t forget. However, there’s no real strict rule on when you should take joint supplements – they don’t contain caffeine, so there are no drawbacks in taking it later in the evening.
As long as you take it daily and provide your body with the ingredients in Performance Lab Flex, then the time you pop the pills shouldn’t matter at all.
Is Performance Lab Flex Really the Best Joint Support Supplement?
I’m one guy that travels the world and runs a website, so I can’t possibly have tried-and-tested all of the joint products on the market.
However, I have looked at many on the market and only found a few to contain effective ingredients without containing pointless fillers.
I’ll keep a eye out and testing other joint products if I’m ever recommended any. And I’ll update this section should I find any better joint support supplements.
For now, I continue to take Performance Lab Flex and haven’t seen a better option on the market.
Where to Buy Performance Lab Flex?
This is potentially the one downside of this product: you can only buy it direct from Performance Lab’s official website, so it’s not available on any 3rd party vendors such as GNC.
I don’t class this as a negative since I always buy online and have it delivered to whichever hostel, apartment or hotel I’m staying in at the time. And the good news is that it’s never arrived late regardless of where I am in the world.
So, if you’re interested in buying this product, you’ll have to head over to: www.performancelab.com
Any Sales or Coupon Codes?
If you’re asking yourself this, then we’ll be good friends. We always check to see if there are any coupon codes available whenever we buy anything online.
The bad news is that there are no coupon codes and Performance Lab don’t often have sales on.
That being said, we did get 10% discount after joining their newsletter for the first time, so you may do too; the sign up pops up onto the screen after a few minutes of being on their website.
Performance Lab Flex Review: Conclusion
I realize that I’ve written a lot of words on this review, so apologies if you’re bored out of your brains by this point. But congrats, you made it to my review conclusion!
The bottom line is that I wouldn’t be recommending this joint support supplement to you if I thought it didn’t work. It has worked for me, in helping keep my joints healthy and reduce joint pain on rest days after long runs (I aim to complete one 5km run per week and run marathons on behalf of charities too).
More good news is that I haven’t experienced any side effects over the 2 year time period that I’ve been taking Performance Lab Flex so far too.
The only real downsides are that you can’t find this product in retail stores such as GNC or Amazon, and that it’s not the cheapest product around. However, I do believe that the ingredients and their dosages justify the cost – you ultimately get a high quality joint support supplement.
