After increasing performance, the next major challenge faced by the sport nutritionist is keeping athletes well and boosting recovery. The field of nutrition for recovery is somewhat clouded in pseudo-science and snake oil, largely because randomised control trials around injury are difficult to perform and therefore the evidence base is a little weaker than with performance nutrition. Fortunately, over the last decade there has been a lot more quality research into nutrition to promote repair and, as a sport nutritionist, we now have several tools available to us to help our athletes. Now, we have a product that has combined all of these active ingredients into a convenient 60ml shot.
Recent research from Keith Baar in the USA has shown that gelatin or hydrolysed collagen in athletes can reduce knee pain as a result of improvements in collagen synthesis. When 15g is consumed there is a two-fold improvement in collagen synthesis, therefore it appears that consuming collagen can not only prevent the rate of injury in athletes but will also be therapeutic in terms of pain management. There are some added extras that are crucial in facilitating the benefits of collagen, including vitamin c and copper. The key with these 2 nutrients is to ensure there is no deficiency hence ‘repair shot’ containing the RDA of both these key micronutrients. Work from Professor Close’s own lab in Liverpool has also shown that many athletes present with vitamin D deficiencies and highlight the importance of vitamin D for muscle regeneration – it therefore made perfect sense to add enough vitamin D to prevent deficiencies and promote an optimal concentration for muscle regeneration.
Finally, the most recent meta analyses and systematic reviews are beginning to provide an evidence base for glucosamine and chondroitin in both pain management associated with osteoarthritis and improving physical function. We fully acknowledge that debate remains in the scientific community on glucosamine and chondroitin, however we know there are no negative side effects and the evidence base is growing. It therefore made perfect sense to include these 2 compounds in the new Repair Shot.
As far as we are aware, there is no other product available that combines an optimal dose of collagen, the extras needed for maximal collagen benefits (vitamin c, copper), glucosamine and chondroitin, as well as a therapeutic dose of vitamin D, all in one supplement. The Repair Shot does exactly what it says on the label and more. A must-take for all serious athletes to prevent injury and maximise repair.
Like all Nutrition X products, the Repair Shot has been registered on the Informed-Sport programme to help protect athletes.
