Looking to reduce joint pain, strengthen your connective tissues, and improve overall joint health? Here’s our guide to the 3 of the best joint supplements in 2023.

Joint supplements are food supplements that improve the comfort and function of your joints by promoting flexibility, repairing cartilage, and protecting your joints from damage caused by inflammatory enzymes and other factors that cause tissue breakdown over time.

All of the supplements in this guide have been thoroughly researched to ensure they are safe, effective, and free of any side effects or questionable ingredients.

Our criteria for picking the best joint supplements include:

  • 100% researched ingredient profile
  • Natural pain relief
  • Ligament & tendon support
  • Flexibility & mobility improvement
  • Healthy for daily use
  • Protection from joint breakdown caused by aging
  • Company reputation & trust

We don’t trial each and every one of these supplements; instead, we compare their ingredients against the scientific data to see if they are safe and effective. This enables us to present you the top 3 best joint supplements we recommend in 2023.

1. Physio Flex Pro – Best Overall

Physio Flex Pro

Physio Flex Pro is a highly effective joint supplement made by a specialist U.K. company, SRS Nutra. It’s been getting a lot of positive attention online, and after checking it for ourselves, we can say it’s currently one of the best supplements you can buy for joint mobility and comfort on the market.

Physio Flex Pro ticks all of our boxes when it comes to;

  • Ingredient quality and effective dosages

The dosages are on point, as well. These include the 4 key ingredients Glucosamine, Chondroitin Sulfate, MSM, Turmeric, and BioPerine. These work together to produce a relief from joint aches, pain, and chronic inflammation, while also protecting your ligaments and tendons from destruction.

The ingredients in Physio Flex Pro have efficiently absorbed thanks to its easy-to-digest formula, and the risk of any stomach upset is low. In the rare case it does happen, we recommend taking Physio Flex Pro with a large meal to avoid this issue.

2. Performance Lab Flex – Best for Active Individuals

Performance Lab Flex

Coming in third place is Performance Lab Flex by Opti-Nutra from the U.K. You’d be forgiven for thinking that it’s inferior to others on this list. Flex is arguably the cleanest-quality joint supplement you’ll find on the market.

It contains patented nutrients developed by Opti-Nutra’s in-house technology. The ingredients in Flex are extremely safe, well-studied, and dosed for light and consistent effects, making it ideal for taking daily without breaks.

You can expect the following benefits from Performance Lab Flex:

  • Improved connective tissue lubrication (less squeaking and creaking)
  • Improved shock absorption and protection of joints during exercise
  • Faster joint recovery
  • Reduced aches and inflammation
  • Improved flexibility and motility

Note that it might take a couple of months before you notice these benefits from Flex. The reason is that it takes time for cartilage and joint tissue to heal and for chronic inflammation to be tamed effectively. Having said that, you may start to notice benefits a lot sooner – it depends on the individual.

Performance Lab Flex contains the following active ingredients.

  • AprèsFlex® Boswellia Serrata
  • CurcuWIN® Curcumin, 250 mg
  • Glucosamine Sulfate 2KCI
  • Mythocondro® Chondroitin Sulfate
  • OptiMSM® Methylsulfonylmethane (MSM)
  • NutriGenesis® Strontium

The ingredients in Performance Lab Flex are natural and as pure as it gets. The formula is highly bioavailable, quickly absorbable, and easy to digest, thanks to the 100% fermented tapioca fiber that the capsules are made of.

Obviously, such a high-quality formula raises the production costs for the company, which is the main reason Performance Lab Flex is second on our list.

However, if you’re looking for the maximum impact joint supplement, and the price is not a problem, get your hands on the supply of Flex.

What We Like

  • 6 patented, science-backed ingredients
  • Dosed for maximum effectiveness
  • Has unique effects such as shock & impact absorption
  • Clean and safe
  • Helps to diminish joint pain
  • Awesome bulk-buy discounts
