Performance Lab Flex Review 2022

Last Updated on February 18, 2022 by Monica Nelson

As a personal trainer that is always on the go, I struggle to find enough time to stretch out my body after intense workout sessions and fitness classes.

Overtime, I noticed something unusual about my mobility—I was losing it. Big-time.

But where was this all coming from?

Tight and ache-y joints and muscles.

I noticed that my flexibility in yoga wasn’t as smooth as it used to be.

I was pushing and pushing during my workouts to get stronger and fitter, but my tight joints were ruining my exercise performance.

Joint health isn’t something that is ever discussed in the fitness world.

We are constantly bombarded with information about how to lose fat, get that perfect waist, achieve bigger glutes, but what about flexibility?

The fact of the matter is, strenuous exercises can affect your joint health long-term if you don’t eat the right nutrition and ignore your stretching sessions.

Which is why I had to do something about it.

I can’t neglect my joint health. It was really bugging me, so I decided I had to try something to help bring back my flexibility.

After doing some research into ‘Joint Supplements’, I discovered a gem. I found a clean, potent joint supplement called Performance Lab Flex.

As I read through the potent ingredients in the formula, I was like OMG. If this is what it says it is, I HAD to try it out.

I bought myself a few bottles to give it a go. I’ll be sharing my Performance Lab Flex experience after 1 year so you can see if this supplement can be something you can benefit from.

If you guys are in a rush, I’ve summarized the main deets below so you can read the quick facts before I explain my Performance Lab Flex review in detail.

Quick Summary: Performance Lab Flex is My Favorite Joint Supplement

I have been using Flex for a while now.

Overall, there is a lot I loved about this supplement – and it helped me achieve my goal of leveling up in yoga!

Performance Lab Flex is packed with anti-inflammatory natural ingredients

Probably my favorite thing about this supplement – the clean and powerful wonder-workers in the formula.

It only contains the best, most bioavailable ingredients to promote joint health and mobility.

Each capsule gives a kick of turmeric, Boswellia, glucosamine sulfate, MSM and chondroitin for that much needed joint TLC.

I felt significant improvements in my mobility

After a year of using this formula, I noticed massive differences in my flexibility and exercise performance. My joints felt more fluid and less tense.

I felt that I could go deeper into my stretches, and my form during yoga is now SO much better.

My joint pain practically disappeared

To wake up without ache-y joints and knees is a magical feeling! Instead of taking forever to warm up before workouts, my joints feel warmed up and ready to go.

Because of the anti-inflammatory ingredients in the formula, it helped tone down my joint pain that I often feel after a tough workout.

Overall, I am very happy with the results and will keep using this joint aid

I never realized the potential of these anti-inflammatory ingredients on my joints and athletic performance. Until I tried Performance Lab Flex out.

I am definitely going to be using this supplement long-term.

If you are keen on trying out this supplement, you can take a look at some of the offers available on Performance Lab’s website.

Performance Lab Flex’s Ingredients

I am in love with this formula. Every single ingredient is in there for a reason.

I really like how all the ingredients are listed in their exact doses per capsule, so I feel confident taking this into my body.

I was so impressed to see that Performance Lab Flex only use the bioactive ingredients in their supplement. Without any hidden junk that is unfortunately common in many cheaper supplements.

All the ingredients are patented forms that have been tried and tested for safety and effectiveness.

This is exactly what you get per dose:

  • 250mg CurcuWIN® Turmeric
  • 100mg ApresFlex® Boswellia serrata
  • 500mg Glucosamine Sulfate 2KCL
  • 100mg Mythocondro® (Chondroitin sulfate)
  • 100mg OptiMSM® (Methylsulfonylmethane)
  • 300mcg NutriGenesis® Strontium

I also found the ingredient descriptions on the website to be very educational and gave me a great insight into how it all works on my joints. All the ingredients work synergistically to promote joint conditioning.

Anyway, without further ado, let’s get into the ingredients of Performance Lab Flex.

Shall we?

The supplement facts label for Performance Lab Flex, clearly showing its ingredients and dosages.


Methylsulfonylmethane or MSM is an organosulfur compound that helps build healthy joints.

It also helps to reduce pain and swelling in the joint area in response to exercise or injury. It’s a fabulous anti-inflammatory compound that can help reduce stress on the joints.

The formula includes a patented form of MSM (OptiMSM), researched to relieve exercise soreness and improve mobility.

It’s also the best form out there, with the highest quality and most-studied MSM on the market.

CurcuWIN Turmeric

I’ve always been familiar with turmeric and it’s wonderful effects on human health. But I realized that my daily turmeric latte won’t cut it – I needed something stronger.

Although I’ve tried a couple of turmeric and curcumin supplements, I never experienced any improvements in my joint pain. Until I took Flex.

Curcumin contains many actives that have been studied to reduce inflammation and fight joint-destructive stress. Additionally, curcumin may protect the cartilage in your joints from degrading.

After digging into the research, I’ve found that curcumin, the bioactive of turmeric, is better absorbed when combined with black pepper.

This CurcuWIN patented form packs a strong punch in each capsule, and is tested to be 46x more absorbable than other curcumin supplements.

Mind-blowing, right?

ApresFlex® Boswellia serrata

Boswellia is a traditional Indian herb that has been shown to boost the immune system and the inflammatory response.

There is a lot of research on Boswellia on joint health, particularly showing that it can protect and soothe the joints.

What I LOVE about Performance Lab supplements is that they put a lot of research into combining ingredients that complement each other. Boswellia and turmeric pair beautifully to help ease joint stress and maximize support.

Glucosamine Sulfate 2KCL

An amino acid that is naturally occurring in the body, glucosamine is so so important for cartilage health and the production of tissues.

Glucosamine also helps to lubricate and cushion the joints to prevent damage from shock and strenuous high-impact exercise.

Mythocondro® Chondroitin Sulfate

A fantastic shock absorber, chondroitin is brilliant for promoting cartilage performance and reducing damage to the joints.

Mythocondro Chondroitin is a highly bioavailable patented form.

Performance Lab Flex Side Effects

This is the best part.

All the ingredients are 100% safe to be taken long-term, with no side effects.

Because Performance Lab follow tight safety regulations and have vigorous testing in place on their products, I feel reassured taking their supplements.

Anyone can take this supplement safely.

However, I do recommend for you to check with your doctor if you are taking any medication, just in case anything counteracts with the natural ingredients in the supplement.

Where to Buy Performance Lab Flex

Performance Lab® Flex is available on their website ( for only $40 for 60 capsules. With the two capsule per day dose, this was enough to last me a month.

I also used their multi-buy offer to get a few months of supplements without having to constantly repurchase. It is a major plus that they offer discounts on the more bottles you buy.

There is also a 5% discount when you purchase two bottles, and a 10% discount for three bottles. Brilliant for stocking up!
