Reviews of Instaflex Joint Support, a supplemental capsule that supposedly relieves aching joints while increasing adaptability.
About Instaflex Joint Support
Instaflex Joint Support is a popular (and heavily-advertised) joint supplement. It is supposed to be a scientifically formulated blend of eight ingredients which relieves soreness and rigidity in joints. Directions instruct users to take three capsules each day with a glass of water. A free-trial of Instaflex contains enough capsules to last 14 days, while larger bottles contain 90 capsules.
Instaflex.com is the official product website. Besides the Instaflex Joint Support, this website also sells other products such as Instaflex Advanced Joint Support, Instaflex Bone Support, Instaflex Multivitamins, and Instaflex Muscle Support.
A disclaimer at the bottom of the Instaflex website reads, “These statements have not been evaluated by FDA. This product is not intended to diagnose, treat, cure or prevent any disease.”
The Instaflex website prominently displays the following ingredients for their joint support formula: Glucosamine Sulfate, Methylsulfonlylmethane (MSM), White Willow Bark Extract, Ginger Root Concentrate, Boswellia Serrata Extract, Turmeric Root Extract, Cayenne, and Hyaluronan. The website does cites a 2013 double-bind clinical study supporting claims that their product is effective. This study allegedly took place at a facility called the Human Research Center in North Carolina. However, there are no links to the study, and it is not clear if it appeared in peer-reviewed science journal.
How Much Does Instaflex Cost?
Instaflex offers a free trial of a 14-day supply, and you must pay $4.99 shipping. Signing up for their free trial will also enroll you in their auto-ship program if you don’t cancel during the trial period:
If you do not call customer service to cancel within  days of ordering your free trial, you will be charged $74.98 plus any applicable tax to the card you used to place your trial order. You will also be enrolled in our auto-ship program.
Further, to be eligible for a refund, you must return the unopened packaging and must have ordered it via standard shipping:
To be considered for reimbursement, products purchased through standard delivery (“all non-auto-ship purchased products”) must be unopened and in the original packaging.
The question that should be most obvious is why do you need to pay $75 per month to have something shipped to you automatically when you can run down to the nearest GNC and buy it for $70 without a subscription? As of this writing, you can buy Instaflex from GNC for $69.99, even less with a Gold Card. I have verified this price on their website and by calling two different stores here in Southern Nevada.
Another obvious issue with this free trial is that it’s doubtful that two weeks is enough time to gauge the effectiveness of Instaflex. A Frequently Asked Questions (FAQ) page on the Instaflex website states that it takes a minimum of three months to realize the full effects, if any.

Reviews of Instaflex Joint Support
Instaflex Joint Support appears to be favorably rated among many users for online vending sites. For example, users on the GNS website give it a collective 4 stars. Amazon users give it 3.5 stars. The majority of online user reviews claim the product works just as advertised.
There are some negative user reviews which are a minority. By far, the most common complaint is that Instaflex Joint Support had no effect at all. An even smaller minority claimed they experienced side effects such as nausea and headache. Others were displeased with the cost of Instaflex, or were upset about being automatically enrolled in the auto-ship program after obtaining their free trial.
If you ever want to read true, non-biased reviews of a product, it’s probably best not to look at the product’s own website, unless you prefer to read cherry-picked or even fake reviews. I’ve found a decent collection of unbiased reviews of Instaflex at supplementcritique.com. I encourage you to read the reviews there, and if you have any experiences you’d like to share here -about the advertising, free trial, or product itself – please feel free to comment below.
It should be mentioned that although Instaflex is not accredited with the Better Business Bureau (BBB), they do maintain an A+ rating with the bureau. This demonstrates that they are at least willing to resolve customer complaints.
Instaflex Joint Support seems to be well-rated by many users online, but some say that it did not work for them. Instaflex does appears to have standard ingredients for joint health, which probably make it on par with other joint supplements out there. We take issue with their free trial, which signs you up for a more expensive auto-ship enrollment if you don’t cancel in time.
Skip the free trial.
If I wanted to try it, I’d just run to the nearest nutrition store and buy it there. And in fact, while at the store I’d shop around for much cheaper alternatives, which do exist.
