The Massive Glucosamine and Chondroitin Scam

The Massive Glucosamine and Chondroitin Scam

Glucosamine and chondroitin act as precursors to the formation of connective tissue. Most research on glucosamine focuses on the knee joint; often these studies are conducted in individuals over the age of 65, with a very specific disorder, osteoarthritis of the knee joint. This is hardly relevant to actively training individuals like yourselves, and in cases more relevant to us (like back pain, shoulder pain, etc.), glucosamine does absolutely nothing (1). In fact, chondroitin itself possesses under 30% bioavailability (2). A large meta-analysis of chondroitin use found that its effects were virtually non-existent (3).

In addition, a 24 month, double-blind study conducted in humans showed that a combination of glucosamine and chondroitin did not have a significant effect in treating knee osteoarthritis. The biggest strength of this study was that it had an extremely large sample size (n=662), in adittion to also using a large dose of both ingredients in the treatment group (4).

Another study with a sample size of 1500+ people found that over the course of 24 weeks, solo supplementation with glucosamine, chondroitin, and the combination of the two had no significant effect on treating pain associated with knee osteoarthritis (5).

So even after all this, why are supplement companies still using Glucosamine and Chondroitin? Monkey-see, monkey-do I guess.

Have you read anything on the purported arterial benefits of chondroitin? Witchdoctory?

The claims are that it is very effective in regards to plaque removal and formation inhibition/prevention (crudely).

 

[Driven2lift]

That study size.
Not often to see that on here,
But joint problems are more mainstream than bodybuilders chasing muscle growth I guess.

Thanks for the share brother.

Guess what ingredients are not going to be in GenoFlex... Lol

Thanks! I'm glad you are doing write ups(even though this may not be technically be a write up), like we requested.

I have heard that the arthritis like pain associated with heavy HGH use is due to not have enough precursors to connective tissue like glucosamine, chondroitin, etc and not consuming enough calcium to compensate for large amounts of calcium that HGH uses. And that supplementing with high doses of these thing can prevent this issue. They also said that it wont reverse it after it has occurred by will prevent it. What are your opinion on that?

 

[HIT4ME]

Interesting read, and something that I suspect many users of these two ingredients already knew first-hand, even though everyone says it is what you should be taking.

Now that you've told us what doesn't work and pointed out a problem, do you have a solution to share? Sorry if that comes across as being either a jerk or a shill - I'm just curious.

 

[Tmac29]

Which version was studied? I keep hearing that Sulfate is much, much better than HCL.

Now we play the waiting game...

 

[Robert5891]

I'm hoping GenoFlex doesn't use either of those.

 

[ahawk01]

I'm hoping GenoFlex doesn't use either of those.

It won't probably one of the reasons posted. I've found out after testing a bunch joint and anti inflammatory ingredients the ais help me much more than glocusomine and such.

TBH I wouldn't put much faith into it. If you want, send me the studies and I can look them over

Hehe, nope

That is just a bunch of broscience. Also, I will be releasing a berberine write up within 2 weeks, then theanine.

Not a jerk or shill at all mate, don't sweat it. Threads are a discussion for all of us, where we can ask each other things. I have a few write ups coming soon regarding this topic (by the end of feb), but I will do berberine and theanine first since I promised people those a while ago

I'm hoping GenoFlex doesn't use either of those.

Nope, never!

 

[carmaf]

Yeah Glucosamine never did anything for me other than it made me fart up a storm BIG time. That's why I had to overlook the SNS Joint Support XT, can't be having those deadly gasses anymore......bad for the environment.

 

[kenpoengineer]

Subbed for more information. I've been using glucosamine in three forms for years - starting as I became very active in martial arts and was experiencing joint pain. I can tell you that when I've stopped taking glucosamine the "clicking" and "snapping" in the knees and ankles returns. This is not "scientific" but a fact for me. In addition, there are other studies that say the opposite of this study - as all studies do. As an example:

THE END OF FEBRUARY!??? BUT I WANT IN NOOOOOWWW!

 

[CATdiesel76]

Never noticed anything with Either so not surprised. Thanks for the writeup. Only joint stuff I take that has seemed to do anything is Cissus, a good Curcumin product, fish oil, and some Joint Products such as Achilles and Joint Force.

Heard good things about big MSM doses in a topical DMSO solution but can't personally vouch for that

2 rank B and every other claim was essentially "unsure" *shrug* sorry mayo clinic, not convinced


But anecdotal feedback in your case matters, if it works it works

Whats the rating for amentoflavone?

Haha

 

[Driven2lift]

Whats the rating for amentoflavone?

Haha

Not sure, not relevant, and I wouldn't use mayo clinic to investigate my supplement choices.

 

[Jiigzz]

Not sure, I wouldn't use mayo clinic to investigate my supplement choices though.

Perhaps not, but the work is cited with references toward the end.

 

[Driven2lift]

I guess I just don't see why that is pertinent or meriting mention here?

Really it's just keeping a thread bumped which I thought companies using these ingredients might not want to.

 

[heavylifter33]

This is why cissus > all.

 

[Driven2lift]

This is why cissus > all.

I always did like cissus, went through a number of bottles of USPlabs Super Cissus
