Looking for the best joint supplements to help combat arthritis, stiffness, and pain? Welcome to Mobility Outreach Intercontinental’s top 3 joint supplement list – now updated.

When most of us think about supplements, we might think of protein powders or multivitamins. Don’t get us wrong, these have their time and place.

But most people start thinking about joint supplements when serious problems begin appearing. These include debilitating joint pain, loss of flexibility, and a decline in the quality of life.

If this is you, and you’re looking for the most effective joint formulas on the market, you’ve come to the right place. In this guide, we’ll see what you should look for in terms of natural ingredients when making your choice.

Here are the supplements we’ve researched on the internet as our recommended options for protecting your joint health long-term.

What Are Joint Supplements and How Do They Work?

Joint supplements are food products that help to ease your joint pain and loss of flexibility by reducing chronic inflammation, promoting healing of your cartilage and ligaments, and inhibiting enzymes that “eat away” at your healthy joint tissue.

  • A quality joint supplement will help to reduce the symptoms of arthritis. It should also increase joint protection and ease of movement.

Everyone from athletes to busy parents, to older folks is using joint supplements to improve their quality of life.

We’ve conducted all the research for this guide, enabling us to recommend what we believe are the best options currently on the market.

Can Joint Supplements Cause Side Effects?

Like with any dietary supplement, there is a risk of side effects depending on your sensitivity levels, medical history, and any allergies or food intolerance.

That said, natural joint supplements are extremely safe. Side effects are rare, and when they do occur, they are typically mild and transient.

The most important tip is to check the ingredients and see if the evidence agrees with the claims from the manufacturer. This will give you a good idea of how safe and effective the product in question will be for you.

Our Criteria

A quality joint supplement needs to be effective, safe, and free of any side effects of suspect ingredients.

PLEASE NOTE: We haven’t personally tested all of the joint supplements on the list. Our main method was to analyze their information on the web, including the ingredients and science behind them to determine if they are worth the money and how they may work for you.

The best joint supplement needs to tick the following boxes:

  • Healthy and evidence-backed ingredients
  • Effectiveness for pain relief
  • Flexibility support
  • Connective tissue protection
  • Cartilage lubrication & shock absorption aid
  • Brand trust & reputation

By using these criteria, we’re able to recommend to you the following three joint supplements.

Best Joint Supplements 2024

1. Performance Lab Flex

Performance Lab Flex

Performance Lab Flex is, without question, the cleanest-quality joint care supplement we’ve seen on the market.

Per words of the manufacturer, Opti-Nutra from the U.K., the nutrients in Performance Lab Flex are nature-identical, making them easy for your body to recognize and absorb. This is thanks to their unique in-house nutrition technology, NutriGenesis®.

Performance Lab Flex helps you with:

  • Pain and inflammation relief
  • Lubricating connective tissues and absorbing impacts
  • Recovery after exercise
  • Strengthening of ligaments and tendons
  • Improving flexibility
  • Supporting long-term joint health

Performance Lab Flex’s Ingredients

Performance Lab Flex provides you with a unique stack of 100% natural ingredients—all clinically backed to lower joint inflammation, extend mobility, and bolster joint function with age. Not a single milligram of capsule space is wasted in Performance Lab Flex.

Performance Lab Flex Ingredients

Speaking of the formula, it’s pure and highly bioavailable. The capsules are vegan and made of fermented tapioca for easy digestion.

Naturally, including so many patented ingredients rises the production costs.

Another drawback for us is that the doses of ingredients like Chondroitin and MSM could be higher. But this can be a positive side for those who want a clean and lightly dosed joint supplement that still packs a punch in terms of benefits.

What made us choose Performance Lab Flex as #1, though, is that it still costs less than many other market-leading joint supplements while being superior in quality.


  • 6 patented ingredients
  • Supports all aspects of joint health & function
  • Provides shock & impact absorption
  • Long-term connective tissue protection
  • Save money when buying in bulk


  • Light ingredient doses for the most part
  • Official product only available at

2. FlexAgain – High-Dosed Joint Care Formula for Maximum Performance

“FlexAgain is a high-end product offering more ingredients, more servings, and more quality.”

FlexAgain is a no-gimmicks joint supplement with some of the most potent ingredients on the market. It immediately caught our attention with its no-nonsense approach to using the best ingredients available, in their highest optimal dosages, while being safe and healthy for daily use.

If you want concrete results in the area of pain, joint tissue repair, and inflammation reduction, get your hands on a supply of FlexAgain.

Flex Again Review

So if it’s so good, why is FlexAgain in second place? It’s only due to its high price tag.

With that said, FlexAgain has far more ingredients than Performance Lab Flex. Furthermore, the ingredients themselves are potently dosed for long-lasting benefits.

If the price is not a problem, FlexAgain can easily claim the title of the most potent natural joint supplement available right now.

Ingredients in FlexAgain include:

  • Omega 3 1100mg
  • Vit D 15 mcg
  • Vit K2 70mcg
  • 250mg of Ginger and Blue Galangal Extract
  • 100mg bromelain
  • 500mg curcumin extract
  • 100mg resveratrol
  • 50mg methylsulfonylmethane
  • 400mg glucosamine  
  • 250mg chondroitin
  • 100mg Boswellic Acid

Benefits FlexAgain aims to give you after using it for 1-3 months:

  • Reduce inflammation & pain
  • Support cartilage recovery
  • Improve your range of movement
  • Promote all-around joint health 
  • Safe & healthy for daily use

FlexAgain is a somewhat new face on the market, but it’s already making waves among people who’re getting real results. The supplement is made in gold-standard cGMP and FDA-approved factories. You can buy it in the US, UK, and many other countries around the world.

FlexAgain also comes with a 90-day money-back guarantee.

3. ProJoint Plus

ProJoint Plus - New Bottle Design

Coming in third on our list is ProJoint Plus.  

ProJoint Plus ticks most of the boxes for us in terms of its ingredients – including MSM, turmeric, chondroitin, Boswellia, and glucosamine.

The dosage is 3 capsules per day with food, or if you want faster pain relief, you can take up to 6 capsules per day for the first two weeks.

While still better than most joint supplements on the market, ProJoint Plus has a few underdosed ingredients. For example, it has only 25mg of MSM per serving, compared to our number one pick which has 100mg of MSM per serving.

With that said, ProJoint Plus’ main advantage is its affordability. A 180-capsule bottle of ProJoint Plus (60 servings) costs $39.95, and a 3-bottle+1 bottle free option (which lasts 240 days) will set you back by $113.94.

Ingredients in ProJoint Plus

ProJoint Plus contains some excellent ingredients for a joint supplement. Here’s a look:

ProJoint Plus Supplement

As we said, the dosages of some of these could be higher for a more potent effect. But, for the money, it is still a thumbs up from us.


  • Some highly effective ingredients in its formula 
  • Excellent customer reviews
  • Helps to diminish joint pain & inflammation


  • Low dosage of some ingredients, including quercetin, MSM, and turmeric

There you have it, this was our best joint supplements guide for 2024.

Our pick of the year is Performance Lab Flex, which offers the highest quality in terms of safety, effectiveness, and clinically-backed ingredients. The longer you take it the more substantial the benefits you should see.

FlexAgain is another great option due to its potent, high-dosed formula with evidenced ingredients. If you need a strong pain relief and something to improve stiffness and swelling, this one should be more effective than any other option we’ve seen so far.

However, all of the products on this list can deliver the benefits, so all of them are effective choices, especially considering the money-back guarantee with FlexAgain and Performance Lab Flex.
