Is There a Joint Supplement that Really Works?

Examining the best joint supplement Australia for 2023…
Joint pain can be debilitating at any age and can be caused by everyday life, as well as certain conditions. Perhaps you suffer from arthritis or osteoarthritis, or related bone or joint conditions. Or your repetitive professional workload — behind a desk, or manual work — causes stiffness and strain. Perhaps even your hobbies, passion or means of exercise also hammers the joints.
Weight lifters, for instance, place incredible stress on their shoulders and back, while runners place strain on knees and ankles, and gamers do the same to their wrists and fingers. Whatever the reason, you don’t need to suffer from joint pain… you can take a daily joint supplement to ease your symptoms.
We reviewed hundreds of products and believe we’ve found the best joint supplement to buy in Australia — Performance Lab Flex.

What Causes Joint Pain?
Joint pain is very common. According to the Australian Institute of Health and Welfare, one in seven Australians have some form of arthritis, with osteoarthritis and rheumatoid arthritis the most common.

- Osteoarthritis is a chronic condition caused when the cartilage that overlies the bones and joints deteriorates. When this protective layer is damaged, the bones rub against surrounding bones, causing inflammation and weakened brittle bones.
- Rheumatoid arthritis is an autoimmune issue, where the immune system attacks its own tissues.
Arthritis results in redness, swelling, pain, stiffness and poorer mobility, and tends to get worse as you age.
Of course, not all joint pain is caused by arthritis. If you have an injury that never fully healed, or suffer with chronic inflammation, you may have damaged the cartilage around your bones or the synovial fluid around your joints.
Lifestyle and professional factors — such as long working long hours at a repetitive manual job or spending most of the day behind a desk can have an impact on joints too. Sitting for long periods of time, for instance, (or after sleeping all night) tends to reduce the synovial fluid that helps to lubricate joints, causing more abrasion and inflammation. Exercise-related injuries and stress, plus highly repetitive activities such as gaming, can also add to the pressure on joints.
High quality joint supplements can be taken every day to help to ease pain, strengthen the bones and joints, and improve your mobility.

The Importance of Caring for Your Joints as You Age

As we age, joints tend to get tighter and mobility decreases, thanks to a condition known as sarcopenia — the natural loss of bone density and muscle mass over time. Bones can become brittle and weak, and the body is less able to recover from falls. It’s a normal facet of ageing, but it can cause stress, pain and impact your quality of life.
If you look after your joints now, whatever your age, by taking an effective supplement each day or a couple of capsules per day, you may be able to delay the consequences of sarcopenia and help to keep joint-related pain at bay. Keeping physically active also helps to reduce your risk of pain in later life, but — of course — you need to be physically fit and mobile enough to do that in the first place!
Providing your joints and bones with the nutrition they need to stay strong, therefore, can pay big dividends. The easiest way to ensure you’re gaining enough of the right sort of nutrients — such as power hitters glucosamine and chondroitin — is to take dedicated joint supplements.
What Is the Most Effective Joint Supplement in Australia?
Here’s our advice and recommendation for the Best Joint Supplement Australia in 2023…
Performance Lab Flex
Performance Lab Flex, from recommended manufacturer Opti-Nutra, combines science with innovation. Unlike other joint supplements that typically have a narrow focus, Flex can work for all lifestyle-related joint concerns. Whether they’re caused by the activities you like to do, your professional life, or by age, Flex can help.

Performance Lab Flex’s flexible formula helps with the following lifestyle causes:
- Professional: Joint strain and injury caused by repetitive movements, such as manual labour or desk jobs.
- Strength training: When weightlifting places stress on shoulders and backs
- Endurance exercise: Such as long-distance running, which impacts the knees, hips and ankles
- Strain from using technology: Texting, typing and tapping can strain the connective tissues in wrists and fingers.
- Age-related: Mobility and joint problems that can occur in the over 55s, significantly impacting quality of life.

The Performance Lab Flex Formula
Performance Lab Flex includes several very clever all-natural ingredients to promote joint health, flexibility, and more besides. It includes two of the heavy hitters in the world of joint supplements — the all-important glucosamine sulfate and chondroitin in the structurally identical form of Phytodroitin.

Glucosamine Sulfate
Glucosamine or glucosamine sulfate is naturally found in the tissues surrounding and supporting the joints, such as cartilage, synovial fluid, ligaments, and tendons. Taking a supplement containing glucosamine sulfate helps to boost the synovial fluid around the joints to aid lubrication, repair and renew cartilage, and form connective tissues.
The glucosamine sulfate used in Performance Lab Flex is sourced from corn, making it vegan-friendly.
Chondroitin
Chondroitin is the natural substance that forms the cartilage surrounding bones and joints. Taking additional doses of chondroitin as a supplement helps to provide the body with more of the building blocks it needs to make stronger cartilage, which provides further lubrication and shock absorption. Boosting the joints’ ability to absorb impact and pressure, for instance, helps to prevent injury.
The version of chondroitin used in Performance Lab Flex is Phytodroitin, made from a blend of seaweed extracts. It is structurally identical to chondroitin and has the benefit of a clear plant source, recognised and welcomed by the Vegan Society and Vegetarian Society. Many other chondroitin supplements include animal byproducts such as shark cartilage. Performance Lab Flex is suitable for both vegans and vegetarians alike.
You tend to find glucosamine chondroitin paired together in many joint supplements as they make a powerful combination.
PLUS:
Boswellia Serrata: linked to an improvement in flexibility, joint aches and the ability to perform daily activities.
Curcumin: linked to improved functional performance, comfort and a lessening of joint stiffness.
NOTE that both of these have been extensively researched, with several modern studies and clinical trials showing benefits for joints; they have also been used in herbalism for centuries, and work better together, forming what Performance Lab describes as the “two best forms of the two best joint-supportive botanicals known to science.”
The final ingredient in the Flex formula includes OptiMSM (Methylsulfonylmethane), needed to form and maintain collagen, cartilage and connective tissues.
