Biotrust joint 33x being a poor supplement with minimal ingredients and ill thought out doses is par for the course for the company. It seems like their goal is to take one cheap ingredient in its correct dose, and then add a couple of other joint pain supplements at a fraction of their tested doses so they can hike the price up.
Biotrust Joint 33X isn't a very good supplement, it relies heavily on tiny doses of hyaluronic acid and collagen, followed by the minimal effective dose of boswellia. Whilst the latter (boswellia) does have some function, the 40mg dose of collagen will be ineffectual and hyaluronic acid does have benefits for joint discomfort, it has to be injected into the site, not swallowed in a capsule form.
You will likely see some benefit from Biotrust, but if we compare it to better supplements on the market, like FlexAgain (which contains the correct dose of 11 ingredients), for minimally more than what Biotrust joint 33x charges for one, we can't really recommend it as a joint health supplement.
Customers reviews of Biotrust Joint 33x are actually not too bad, but like most single joint health supplements of it's type, that include at least one well dosed ingredient, joint 33x will promote joint health and the majority of people that see any improvement are going to be reasonably positive.
The difference in our score is that we're comparing Joint 33x against the best supplements on the market. There are a few people that report Biotrust Joint 33x side effects, unfortunately this is something that can happen when taking boswellic extracts.
The most commonly asked questions from Biotrust Reviews
Joint 33X should be safe, there are some side effects that can present as a result of boswellia, typically nausea, which can be partially mitigated by taking it with food. It has no known severe or moderate interactions with any medications.
Biotrust Joint 33X on Amazon is generally a little bit more expensive than it is on their own website, but then again there are a lot of plain Boswellia Serrata supplements that you could get on Amazon instead.
Boswellic Extract 100mg - As we've already mentioned Boswellia is a good ingredient, even dosed at 100mg, although this is the lowest dosage that's been shown to improve joint function.  Boswellia works by reducing the impact of enzymes which attack joint cartilage, and the supplement has shown efficacy in reducing the impact of multiple chronic health conditions including osteoarthritis.  It does also have some noted benefits to brain health as an added bonus. This is the one ingredient that does all of the heavy lifting for biotrust and is the only real positive in our biotrust joint review.
Type ii Joint Collagen 40mg - Supplementing type ii joint collagen does have some impact on retaining healthy joints., and there is one double blind placebo controlled study which showed 40mg supplementation of type 2 collagen improved joint function.  However, the trial was only of 55 people and there are as more trials showing supplementation needs to be higher than this.
Hyaluronic Acid 40mg - Unfortunately hyaluronic acid needs to be injected onto the site and in a higher dosage (240mg most commonly). It's been regularly studied and contrasted to the performance of other dietary supplements for joint health, such as glucosamine. At one point it was believed that hyaluronic acid could not be absorbed orally at all. It seems that joint 33x may be on to something in that recent studies suggest it can be, however, the catch is, that it is still difficult for the body to absorb it. Meaning that 40mg is likely to do very little at all when it's going to be even less effective for improving joint health than injecting into the site directly. And the dosage in Joint 33x wouldn't even be enough for that.
There isn't really much of a competition between our top rated joint supplement and BioTrust. FlexAgain contains the two ingredients that work in Biotrust joint 33x as well as a host of other more effective ingredients like curcumin, omega 3, eurovita, bromelain amongst others. And the fact that it costs $49 per bottle vs FlexAgain's $60 a bottle really makes this no comparison. Even if you took half doses of FlexAgain you'd still get more value from it than BioTrust Joint 33X and improve joint health quite a lot more effectively.
BioTrust Joint 33x is a terrible value supplement, it does have one ingredient in a functional dosage, but you could get this for around $10 a month and the rest is either ineffective or in too low of a dose to improve joint mobility or improve joint discomfort. There are much better over the counter supplements available in the same price range that do more to improve overall joint health. We do not recommend BioTrust Joint 33X and recommend that you either just get a boswellia serrata pill to save money, or get FlexAgain instead if you want something that is a catch all for overall joint health.
