Top 5 Joint Supplements
One of the fastest-growing supplement categories today is products that address joint discomfort, often stiffness, achiness, and limited flexibility. The good news is that the right joint support supplement can help support flexibility, mobility, and cartilage health while easing joint-related discomfort. Some formulas contain ingredients that can have you seeing results in as few as 5 days.
With roughly 92 million Americans reporting the inability to enjoy everyday aspects of their daily lives due to joint discomfort, it is no surprise that hundreds of joint support supplements are flooding the marketplace. We have all seen and heard so many TV, radio, and online ads from brands promising benefits, but the reality is that many fall short. To that end, some of the most advertised brands use ineffective generic ingredients with little clinical studies. Worse, many contain low-quality fillers that may have negative health consequences.
How To Pick A Good Joint Support Supplement &
Avoid the Junk
With so many choices, figuring out what to look for in a good joint support supplement can be challenging. To make your life a tad easier, we’ve done months of research and pulled together the key ingredients that can help ease joint discomfort, improve flexibility and mobility, and get you back to playing twister in no time!
This short guide is here to help you discover what to look for and steer clear of when it comes to your joint support needs. Plus, we’ll share a list of the five best joint support supplements available today!
Let’s take a moment to understand precisely how joint supplements work and why adding them to your daily routine is essential.
Joint Supplements
What Are They All About?
Joints are the places in the body where two or more bones meet. They are made of bones and soft tissues, such as cartilage, tendons, ligaments, and nerves. From the smallest, most mundane tasks, like brushing your teeth, to exercising, playing pickleball, or golf, your joints make all movement possible.
As we age, our joints can be impacted by many things, and joint discomfort can accelerate with an injury or accident. For example, osteoarthritis is a degenerative ‘wear and tear’ joint disease that causes joints to naturally wear and tear down with time and use. Acute inflammation is another factor that greatly impacts overall joint health and can lead to swelling and discomfort. A compromised immune system or common viruses can also cause damage to your joints.4-6
The good news is the right active ingredients in a joint supplement can help repair worn-down joints, ease acute inflammation, and add lubrication while supporting the long-term health of your joints.
What Causes Joint Discomfort?
Over time, the cartilage that cushions the joints can wear away, leading to a condition called “bone-on-bone” friction. This deterioration can cause significant discomfort and restrict movement. Additional issues like bone spurs from long-term friction or decreased synovial fluid, the natural joint fluid that lubricates the joints, can exacerbate the discomfort and lead to further complications and discomfort.9
Injuries such as sprains, strains, and fractures can affect joint discomfort and mobility. If they do not heal properly, these injuries may cause immediate joint discomfort or develop into chronic issues. Swelling and stiffness are common symptoms of these injuries as the body attempts to protect and heal the affected area. 10
There can be a correlation between joint discomfort and low levels of Vitamin D. People with joint discomfort often find themselves trapped indoors, lacking exposure to Vitamin D and sunlight, because joint discomfort causes them to stop many of the daily activities that once brought them outdoors.
These low levels of vitamin D can lead to joint discomfort. Vitamin D is essential for healthy joints as it eases cartilage degradation, potentially preventing the development and progression of osteoarthritis. 11-13
3 Things To AVOID
When Buying A Joint Support Supplement
1. TITANIUM DIOXIDE & OTHER CAPSULE COLORANTS
If you look closely at the label’s ingredient section, you’ll see “other ingredients” listed. This is where ingredients like Titanium Dioxide, FD&C Blue No. 1, Red 3, and other harmful ingredients can be hidden.
Titanium dioxide is widely used in many popular joint support supplements to give the capsules a uniform, bright white color, making them more visually appealing to consumers. However, the drawbacks of using this ingredient far outweigh the benefits. This additive has been associated with DNA damage, acute inflammation, liver and intestinal toxicity, an impaired immune system, and even adverse effects on the gut microbiome.20-22
While this ingredient is still allowed in the United States, the European Food Safety Authority (EFSA) declared it unsafe for consumption and, as of 2022, banned its use as an additive in supplements.
Similarly, a Public Health Advisory was issued in 2003 on the use of capsule colorants FD&C Blue Dye No. 1, a synthetic blue dye that’s used in many products, including supplements, candy, and cosmetics.23,24
While titanium dioxide, FD&C Blue No. 1, and Red 3 are widely prevalent in joint supplements, we recommend avoiding them and instead looking for a more consumer-health-focused brand that uses cleaner ingredients.
2. GLUCOSAMINE & CHONDROITIN
Glucosamine is a natural compound found in cartilage.
It’s often touted on supplement bottles as an all-star necessary ingredient for joint comfort. However, in many clinical trials, glucosamine was shown to be either ineffective or showed small and arguably clinically unimportant treatment effects.25
Often, brands combine glucosamine with chondroitin, which has also shown to be ineffective.26-29 In a 2016 study, 164 patients with knee discomfort due to osteoarthritis were either given a combination of glucosamine and chondroitin or received an identical placebo pill. The study was stopped early because those taking the supplement actually reported worse symptoms than those taking a placebo.30
This compelling research is why we advise you to look beyond these ingredients and seek out supplements with clinically backed, more efficacious ingredients.
3. ADDED CALORIES AND CARBOHYDRATES
While conducting extensive research, the team at Review Scout was shocked to discover that numerous joint supplements on the market today contain unnecessary calories and carbohydrates. When you see calories or carbohydrates listed on a supplement, it’s a stark indication that the supplement contains inflammatory-causing additives like gelatin, oils, sugar, starches, or sweeteners.
When a person has arthritis, the body is said to be in an inflammatory state. That’s why you want to avoid these harmful additives at all costs.
Along with titanium dioxide, FD&C Blue No. 1, and Red 3, we also recommend avoiding supplements that contain calories and carbohydrates and instead sticking to brands that omit these ingredients.

CONS
- Users complain of the large capsule size despite the bottle advertising a small pill
- Contains titanium dioxide additive
- Contains FD&C Blue Dye No. 1
- Only a 30-day money-back guarantee
- $2 per capsule
Why We Chose It
Instaflex is a doctor-formulated joint health supplement that we are pleased to see contains the superior form of AprèsFlex Boswellia serrata as well as additional joint-supporting nutrients, including hyaluronic acid and turmeric. The brand took additional steps to validate its formula with third-party testing. However, at $60 a bottle for a 30-day supply, it seems as if the customer is absorbing this cost. When you add in the cost of shipping, Instaflex Advanced Joint Support is over $2 per capsule, making this one of the most expensive joint supplements on the market.
Although it’s great that they included Type II collagen derived from chicken sternum cartilage, they left out Types I, V, and X and failed to include MSM.
Instaflex includes titanium dioxide in its capsule formulation, which is a concern for anyone concerned with their health. And arguably more alarming to us was their additional use of the harmful colorant, FD&C Blue Dye No. 1, clearly known to cause damage.
Although the product is marketed as having a small pill size, user feedback often points to the capsules being uncomfortably large, contrary to what is advertised. Furthermore, the product’s guarantee only covers 30 days, which may not be sufficient for users to assess its effectiveness fully.

- User Rating 7.8/10
PROS
- Contains MSM

- Contains Hyaluronic Acid
- 60-day return policy
CONS
- No Turmeric
- Users complain of large capsules
- Contains titanium dioxide
- Contains glucosamine & chondroitin
- 10 calories and 2 carbohydrates per serving
Why We Chose It
Osteo Bi-Flex included 1500 mg of MSM and 100mg of Boswellia Serrata extract in its formulation. Their Boswellia Serrata extract is in the form of 5-LOXIN®. We appreciate that 5-LOXIN has been clinically tested and has similar anti-inflammatory properties for treating osteoarthritis and joint discomfort as AprèsFlex, used in our top-rated brand. However, this still ranked inferior to ApresFlex®. Our preferred AprèsFlex delivers enhanced bioavailability, which allows for greater efficacy at lower doses and faster relief from acute inflammation and joint discomfort.47
A disappointing discovery was that this supplement contains both calories and carbohydrates. One daily serving of Osteo Bi-Flex has 10 calories and 2 carbohydrates. We can only assume those carbohydrates and calories come from the extensive list of “other ingredients,” which includes titanium dioxide.
Although Osteo Bi-Flex provides a generous 60-day return policy, we noticed that this brand sells 80 capsule bottles. At their 2-capsule dose per day, users will inconveniently run out of servings mid-month. After just 40 days.

- Contains Hyaluronic Acid
- 90 Day Return Policy
- Doctor Backed
CONS
- Contains glucosamine
- Contains generic Boswellia Extract
- No Collagen
- Low Amazon rating
- Users complain it doesn’t work
Why We Chose It
Synocell is a doctor-backed joint health supplement that we are pleased to see contains three of the four essential ingredients: Boswellia serrata, Methylsulfonylmethane (MSM), and additional joint-supporting nutrients, including hyaluronic acid. Although we were happy to see the addition of Boswellia serrata, this brand is lower on the list because they added a generic form versus the top two brands who used superior, fast-acting relief, AprèsFlex®Boswellia serrata. We were disappointed to see this product relies on less efficacious glucosamine as one of its hero ingredients, which research shows to be ineffective. Synocell also advertises that it contains both glucosamine and chondroitin, yet there is no chondroitin listed in the supplement facts, confusing consumers. Furthermore, this supplement contains shellfish(shrimp, crab, crayfish, lobster), which the glucosamine comes from, which is not good for people with shellfish allergies.
Many user reviews claim this product doesn’t work, which is probably why a very low Amazon rating of 3.4 out of 5 is a cause for concern.
We were happy that this product offers a 90-day return policy and contains no titanium dioxide, capsule colorants, or added calories or carbs.

Overall Grade
#5 Move Free Advanced Glucosamine Chondroitin MSM Joint Support Supplement
- OVERALL RATING 7.2/10
- Predicted Effectiveness 6.7/10
- Ingredient Quality 7.1/10
- Value 6.6/10
- Return Policy 8.8/10
- User Rating 6.8/10
PROS
- Contains 1500mg of MSM
- Contains hyaluronic acid
CONS
- No Boswellia Serrata
- No Collagen
- No Turmeric
- Contains titanium dioxide
- Relies on glucosamine & chondroitin as two of its hero ingredients
- Contains modified corn starch adding 5 Calories to each capsule
- 3-tablets per serving
Why We Chose It
Move Free has made a mark in the joint care market with its substantial 1500mg dose of MSM.
However, Move Free faces several challenges. Notably, it lacks Boswellia serrata extract, an essential anti-inflammatory agent that many top-tier joint supplements include. Instead, it relies on less efficacious glucosamine and chondroitin as two of its hero ingredients.
Their formula not only contains titanium dioxide as an additive but also includes modified corn starch, which adds 5 calories to each serving.
Their recommendation of three tablets per serving might also deter users.
What we found to be suspicious is the lack of readily available information on their return policy, leading us to believe there is none.
