Tri-Flex GNC Ingredients and Side Effects
|Chondroitin Sulfate Sodium
Hyaluronic Acid: A popular additive in more recent joint health supplements. Hyaluronic acid is a lubricant found in humans’ synovial fluid that helps joints, cartilage, and bones all work together pain free. Clinical studies are still determining its effectiveness, though there do not seem to be any major side effects associated with hyaluronic acid. It does come with these consumer warnings, however:
- There is a risk of allergic reaction to any product that contains hyaluronic acid.
- There have been some medicinal interactions and those taking prescription blood thinners or heart medication should consult with their physician before use.
- It is recommended that pregnant or nursing women avoid hyaluronic acid.
Glucosamine Hydrochloride: Also a common additive for joint health supplements, glucosamine is known to stimulate the body’s natural cartilage and synovial fluid manufacturing and repair. Glucosamine is frequently used to combat arthritic conditions and has been shown to aid in overall health and immune functionality. There are few side effects associated with glucosamine, the most serious of which is a potential allergic reaction (though those cases are rare)
Chondroitin Sulfate Sodium: Another one of the more basic additives in joint health products. Usually derived from sharks or cows, chondroitin is used to combat a number of ailments including osteoarthritis, osteoporosis, and heart disease because of its ability to help stimulate the body’s natural collagen production abilities. There are very few known side effects connected to glucosamine consumption, though potential allergic reaction is possible.
MSM: The last main active ingredient listed by GNC for their product is another one of the most-used ingredients in leading joint health supplements. Dimethyl Sulfone is derived from green plants and used in a variety of over the counter treatments for conditions such as osteoarthritis, rheumatoid arthritis, and lowered immune functionality.

Tri-Flex GNC Quality of Ingredients
Individually, there is nothing wrong with the ingredients of Tri-Flex GNC. They are all included on the list of most frequent additives for reputable joint health supplements and have been shown to be highly beneficial for both long- and short-term joint health. Chondroitin and glucosamine especially are found in nearly every effective joint health product because they actually help improve the body’s ability to produce collagen and synovial fluid on its own as opposed to merely treating the symptoms or masking the pain of joint issues, as many other supplements do.
But that’s also the problem with Tri-Flex: every OTC joint supplement on the market that’s at all effective should be utilizing all four of these ingredients – and hopefully several more, too. There is nothing in GNC Tri-Flex that would set it apart from any other halfway decent brand available today
Boswellia extract, boron, and bromelian have all been shown to work well in conjunction with glucosamine, chondroitin, and MSM, increasing the overall effectiveness of any given supplement. GNC has not chosen to include any of those chemicals in their mix.

The Price and Quality of Tri-Flex GNC
GNC sells Tri-Flex GNC through their website and through their terrestrial locations as well. Generally a consumer should expect to pay:
- 1 Bottle of 120 caplets (non-members): $37.99
- 1 Bottle of 120 caplets (members): $29.99
They offer free shipping on orders over $49 dollars and a 10% bonus for signing up for their membership program.
This is a fairly high price for a joint supplement, especially for one with such generic ingredients. There is nothing wrong with Tri Flex’s GNC proprietary blend, but there is also nothing in it that would suggest you should by it over brands that offer more diverse ingredients or better cost efficiency.

Customer Opinions of Tri-Flex GNC
Most online reviews are mildly positive, which is to be expected given Tri-Flex GNC’s ingredients. There were some more negative comments that could be found including these:
“One star – didn’t help my arthritis at all.”
“When I got my pills they were surprisingly close to the expiration date, and some were moldy.”
“Used it for a couple months, then switched back to my old supplements when I started experiencing pain again.”
The most frequent negative reviews had to do with the product not working, however there were a strange amount of individuals like the one above that received what seemed like old pills. There were numerous reports of pills being received close to their expiration date, despite the fact that at the time of manufacture most of those dates are set years in the future. There were also reports of pills being dusty, moldy, or tasting “stale” or “off.”
