Performance Lab Flex Review Overview
Performance Lab Flex is easily one of the best joint supplements on the market today. Unfortunately, it doesn’t seem to actually exist! This product has been OUT OF STOCK for months now. It went out of stock a while back and we were promised it would never go out of stock again, which clearly didn’t turn out to be true. A representative at Performance Lab told us this is an inevitable consequence of growth; not only is this stupid, but it means nothing to us, the end users. So despite having a good formula (albeit a little expensive for what it is), we cannot possibly recommend Performance Lab Flex to our users. It is also very expensive compared to most joint supplements.
Performance Lab Flex Reviews – What does this joint supplement do?
Joint supplements don’t get written about very often. Compared to other health and performance products, supplements for joint health hardly get mentioned on health or fitness blogs. But that is starting to change in large part due to the dramatic improvement in the quality of joint supplements in recent years.
Performance Lab Flex is a cutting-edge joint supplement. People are claiming that it is completely changing the market. Why is this stack making so much noise? What does it do exactly?
Performance Lab Flex is designed as a complete joint supplement. It takes a multi-faceted approach to promoting joint health. According to the website, it can:
- Protect connective tissues from damage
- Soothe worn joints and reduce inflammation
- Help lubricate joints to promote flexibility
- Reduce pain and swelling
- Support the synthesis and repair of cartilage
- Promote bone density
That really is one impressive list of benefits. Most joint supplements just provide a few vitamins thought to reduce inflammation. Very few products aim to provide total joint protection and flexibility support.
The important question is, does Performance Lab Flex really do all of this?
Does Performance Lab Flex really work? Can it increase flexibility? Is it safe? Is it the best joint supplement on the market right now? You can find answers to all of these questions in our complete Performance Lab Flex review below.

Note about Performance Lab Flex’s formula
One thing we need to mention right away is the unique quality of the ingredients used in Flex. Performance Lab is building their reputation on purity, precision and mimicking nature. The ingredients used here are all extremely pure, sourced from vegetables, and in the case of Strontium, grown especially for Performance Lab using prebiotic bacteria. As far as we know, this is unparalleled in the supplement industry.
We’ll now go through each Performance Lab Flex ingredient one by one. In each case, we’ll tell you what it does, how it works, and what the scientific evidence has to say about it. We’ll then tell you what we make of the formula as a whole. Please post your questions – or your own reviews – in the comments at the end.
CurcuWIN Turmeric – 250mg
Turmeric is a staple ingredient in joint supplements. So it should be; there is a mountain of clinical data showing that turmeric supplementation – in high enough quantities – dramatically reduces inflammation and alleviates joint pain. It is the curcuminoids in turmeric which give it all its health-promoting properties. Of these, curcumin is the most powerful.
Curcumin supports better joint health and flexibility in a number of different ways: fighting free radicals which damage your cells and erode your joints; promoting cartilage growth and repair; modulating inflammatory enzymes like COX-2 and destructive enzymes like MMP, and more. Some studies have even found that large doses of curcumin can reduce advanced glycation end-products, which is what causes the stiffening of the joints that comes with age.
Performance Lab Flex uses CurcuWIN – a highly potent turmeric extract. CurcuWIN has been specially formulated to be super bioavailable; 46 times more bioavailable to be exact. CurcuWIN is 20% curcuminoids, with ratios the same as fresh turmeric. This really is cutting-edge stuff. It doesn’t get any better.
ApresFlex Boswellia serrata – 100mg
Alongside curcumin, Boswellia serrata is one of the two core, staple joint supplement ingredients. Every modern, high quality joint supplement should contain a decent serving of Boswellia serrata extract.
Boswellia is a unique source of compounds called boswellic acids. Recent research has found that boswellic acids can inhibit the function of the enzyme 5-Lipoxygenase. This enzyme breaks down cartilage over time. By inhibiting this enzyme, boswellic acids protect your cartilage from degradation, keeping your joints safe and functioning properly throughout life.
Performance Lab Flex uses a Boswellia serrata extract which has been refined to provide 20% AKBK. This is the boswellic acid most effective for improving and protecting your joints. Several clinical trials have found that 100mg of high-AKBK extract can dramatically reduce pain scores in people with knee problems such as osteoarthritis.
Glucosamine sulfate 2KCL – 500mg
Glucosamine is an absolutely phenomenal supplement for improving flexibility and reducing joint pain. In our opinion, it should be in every joint supplement on the market.
Glucosamine is an amino sugar found in large quantities in the tissues that constitute and surround your joints. High concentrations of glucosamine in your cartilage, tendons, ligaments, and the surrounding fluid which keeps your joints lubricated. Declining levels of glucosamine will contribute to erosion of your joints and decreasing flexibility. If you’re worried about joint wear-and-tear, glucosamine is a must!
Rather than using shellfish – like most supplements – Performance Lab Flex uses corn as its source of glucosamine. The Glucosamine sulfate 2KCL in Flex is readily absorbed and utilised by the body. The 500mg serving is very generous; clinical trials have reported serious benefits using less!
Mythocondro – 100mg
Mythocondro is a branded form of Chondroitin sulfate. This molecule is extremely important for your joints.
The reason chondroitin is useful is because it is negatively charged. Basically, chondroitin is woven through your cartilage – or rather, the empty space surrounding them. It attracts water molecules and holds onto them. In doing so, chondroitin keeps your cartilage lubricated, provides some shock absorption, and promotes the growth and repair of existing cartilage cells.
Anyone who regularly does high-impact cardio like running, sprints, or jumping should consider using chondroitin to help alleviate impact damage.
Performance Lab Flex uses Mythocondro. This is an extremely potent form of chondroitin. It is over 40% more bioavailable than the next best form of chondroitin. On top of that, it is the only vegan form of chondroitin. Most forms contain animal by-products such as pig or even shark cartilage. Yet another example of Performance Lab spending more money to provide a superior product.
OptiMSM – 100mg
Methylsulfonylmethane (MSM) is a vital structural component of most of your connective tissues and your cartilage. It is actually one of the necessary nutrients for the formation of glucosamine, chondroitin, and cartilage. This makes it a fundamental building block of your joints, and a crucial nutrient for maintaining joint function.
Upping the availability of mtheylsulfonylmethane through supplementation is a great way to improve flexibility, slow down the degradation of cartilage, and protect your joints from wear-and-tear.
MSM has been widely used in joint supplements for some time; it is safe, reliable, and effective. Some clinical trials have noted that it is effective for reducing pain and inflammation in people with knee problems.
NutriGenesis Strontium – 300mcg
Strontium is not found in your run-of-the-mill joint supplements. Few manufacturers seem to understand how important strontium is for maintaining motility and flexibility. It is particularly important to consider as you get older.
Strontium has two incredibly powerful effects on your body: stimulating the synthesis of osteoblasts (cells which grow bone tissue), and hindering the activity of osteoclasts (cells which break down bone tissue).
Performance Lab use their own proprietary process when synthesizing vitamins, minerals, and amino acids – a process they call NutriGenesis. Basically, they take single-celled organisms like yeast, probiotic bacteria and botanicals, and feed them micronutrients. They place these organisms in a hydroponic medium and allow them to grow. This essentially grows micronutrients that are bound within probiotics, antioxidants, and proteins – just as they are found in nature. Flex provides 300mcg, which is plenty.
Formula analysis: Is Performance Lab Flex any good?
This is an absolutely brilliant supplement for your joints. As far as we’re concerned, Performance Lab Flex is the single best flexibility, motility and joint health supplement currently on sale.
The thing that sets this product apart is the quality of the ingredients.
For each ingredient, Performance Lab Flex uses the purest, most potent, highest value form in existence.
Most joint supplements contain some turmeric because of its anti-inflammatory properties.
Performance Lab Flex instead uses the significantly more potent (and much more expensive) CurcuWIN. This provides a massive dose of curcumin that protects your joints from free radical attack, inhibits joint-eroding enzymes, and reduces inflammation.
CurcuWIN is over 40 times more bioavailable compared to consuming simple turmeric. So in paying a little bit more for a better ingredient, Performance Lab are giving you over 40 times better value. They lose a tiny amount of profit so you gain a lot of benefits.
It’s the same story with the other ingredients in Performance Lab Flex.
We get Glucosamine sulfate 2KCL instead of regular glucosamine – more bioavailable and more readily utilized by your connective tissues.
We’re given NutriGenesis Srontium instead of regular Strontium – this is Strontium “grown” on probiotic bacteria cultures, and is as close to nature as you can get.
We don’t get simple chondroitin from this stack, we get Mythocondro – 40% more bioavailable and the only vegan form of chondroitin in existence.
You can’t argue with ingredient quality like this. The attention to detail and the money that has gone into developing Performance Lab Flex is obvious. A fantastic joint supplement in every respect.
Performance Lab Flex ticks every box as far as we’re concerned. It is extremely powerful, it promotes joint health in multiple different ways, and the ingredient quality is unmatched.
If you’re looking for a supplement to help with joint pain, stiffness, flexibility issues, or you just want to prevent wear and tear, Performance Lab Flex would be a great purchase.
Performance Lab Flex Side Effects: Is it safe?
Joint supplements are, generally speaking, very safe.
Side effects are extremely rare with regards to supplements for joint health. They usually contain natural herbal extracts and minerals which promote flexibility and increase the strength of your connective tissues.
You are highly unlikely to experience negative effects while consuming such substances.
Performance Lab Flex is a great example of this; it contains nothing but natural herbal extracts, amino sugars, and minerals known to improve flexibility, mobility and to reduce joint pain.
None of the ingredients in Performance Lab Flex are thought to cause side effects.
Follow Performance Lab’s usage directions and you should not experience any adverse effects whatsoever.
That said, everybody is different. It is always possible that you are intolerant to a substance that is perfectly safe for 99.9% of people. That’s why it is so important that you do your research and get proper medical advice before trying any new joint supplement.
You must do your own research carefully before using any joint supplements. It doesn’t matter how safe they seem to us. Talk to a qualified health professional before using any new supplements, including Performance Lab Flex. We are not doctors and this is not medical advice!
Performance Lab Flex Review Summary: Is it worth buying?
In our opinion, Performance Lab Flex is a high-quality joint supplement.
It contains several quality ingredients tha have been clinically proven to ease joint pain, increase flexibility and protec joint health over the long-term. Importantly for us, Flex promotes flexibility and joint health in multiple different ways at once.
The fact that you get total joint support for just $1.63 per day is incredible. Few join supplements offer this kind of value for money, even if it is slightly more expensive than a lot of other products on the market right now.
However, there are some serious issues with this product.
The biggest problem with Performance Lab Flex is stock. Unfortunately, due to manufacturer incompetence, this product is perpetually out of stock. The chronic stock outages aren’t likely to end any time soon. We asked someone at Performance Lab what was causing the stock outage, and a representative told us that they believe it is a consequence of growth. When a company sees stock outages as inevitable when moving such modest amounts of product, they’re clearly not going to address the problem.
Worse still, we have heard from dozens of people who ordered Performance Lab FLex months ago and are yet to receive their product, a refund, or even any communication from Performance Lab about the missing order.
We cannot recommend a joint supplement to our readers that only exists in theory.It doesn’t help you, the end user, find pain relief or joint support.
Performance Lab Flex sure looks good on paper, but until it actually exists, we think you are better of taking joint supplements that can help provide joint pai relief right now.
