What is StimTein?
StimTein is a joint pain supplement that the manufacturer’s claim contains a ‘little known FDA-cleared nutrient’.

The official website for StimTein is basically an unprofessional looking page of information that consists mainly of customer testimonials and over-exaggerated statements.
The overall impression the consumer gets from reading the website is of a ‘too good to be true’ product of which very little details are given.
The site does contain a video testimonial presentation and, as mentioned, numerous written ‘case histories’ where the customers claim to have experienced complete pain elimination in as little as 6 days.
The remainder of the company website explains how this ‘hot-out-of-the-box’ scientific discovery works to actually perform the act of building the stronger cartilage needed for healthy joints, likening the process to building a wall.
The manufacturers are so confident that the formula will work that they offer a money back guarantee.
StimTein – Facts
The only ingredients listed as being in the joint relief product are the ‘Bone Activating Proteins’ which are known in medical terms as ‘morphogenetic’ proteins. Although it is not explained on the StimTein website, these morphogenetic proteins actually induce the formation of bone cartilage, an important component of healthy joints. Another effect of these proteins is to reduce inflammation, redness and swelling, the main cause of pain in these areas.
In the case of StimTein, the ‘Bone Activating Proteins’ are used in the place of the more commonly found ingredients Glucosamine and Chondroitin[1]. The site details clinical studies which showed the proteins to be superior to the Glucosamine/ Chondroitin combination in creating new cartilage, plus, StimTein is suitable for those who cannot take these substances due to shellfish allergies.
No dosage instructions are given on the website, but it is known that the product should be taken on a consistent basis in order to maintain strong joints.
Other Ingredients are Steric Acid, Magnesium Stearate, Silicon Dioxide[2], Dicalcium Phosphate etc.

StimTein Review – The Conclusion
While it seems as though the use of ‘Bone Activating Proteins’ has a positive effect on the formation of healthy joints, it is unfortunate that the information for StimTein is presented in such an unprofessional manner.
There is indeed evidence that morphogenetic proteins are an important part of joint pain medications, although this raises the question of why they are not included in more over-the-counter brands.
Until more is known about these proteins and providing the user has no allergies to shellfish, it would be wiser to take a Glucosamine/ Chondroitin-containing product and preferably one that also contains anti-inflammatories and lubricating substances. You can also go for other best joint supplements in the market which might offer more benefits than this product.
