TARFU: LaBrada Nutrition Financed Study Finds no Effect of Super Charge Xtreme N.O. on Training Induced Increases in Muscle Size. Minor Effects on 1RM Max.

As mentioned in previous blogposts, I highly credit all supplement companies which - instead of just putting out untenable claims about the "steroid-like" effects of their products - spend a few bucks of their immense marketing budgets on research on how fantastic their products actually are. In the case of LaBrada Nutrition's Super Charge Xtreme N.O. it does yet seem that it would have been wiser to do some research before formulating their new "NO booster".

Other than the guys over at LaBrada Nutrition probably have hoped or even expected, the study (JSCR. 2011) that was published in the March issue of the well-known Journal of Strength & Conditioning Research found no "significant improvements in LBM over the placebo drink" and only minor increases in bench press 1RM and squat power, which may well be attributed to CNS stimulation due to the hefty 450mg load of caffeine each serving of Super Charge Xtreme N.O. contains.

Other than that, the "15 physically active, resistance trained, college age (19.5 +/- 0.269 yr) males" in the placebo group attained the same changes in body weight, body [as measured via dual-energy X-ray absorptiometry (DEXA)] and maximal strength in the rest of the 8 different exercises of their 3-day/week exercise regimen:

A main effect for time was identified for each of the 1RM strength measures tested (p<0.05) except biceps curls (p = 0.34). [....] Significant main effects were found for lean body mass (F1/22 = 20.32, p<0.001), but there were no significant group x time interactions for changes in LBM (F1/22 = 0.142 p = 0.710).

But let's be honest. Did you still believe an NO booster will improve your gains? I, for my part, take them for the feeling of being pumped up. And although I have not yet had the chance to test this particular product, I am inclined to believe that it will provide similar results as the classics like NO Xplode & Co - that kind of cosmetic pump you either love or hate.

Want to Stay Lean on a High-Fat Diet? Consume Whey Protein Everyday.

Listeners of Carl Lenore's Super Human Radio already know: Dr. Paul Arciero of Skidmore College is going to publish a study the results of which confirm that obese individuals can lose weight and improve markers of metabolic health by just adding a 20g shake of whey protein 3x a day.

While you still have to wait for the detailed results of this study to be published, another group of scientists (Shertzer. 2011) derived similar results from a study on mice. Despite being on a high fat diet, mice who received 100mg of whey protein isolate (WPI) per liter of their drinking water (WPI group) ...

had lower rates of body weight gain and percent body fat and greater lean body mass, although energy consumption was unchanged. These results were consistent with WPI mice having higher basal metabolic rates, respiratory quotients, and hepatic mitochondrial respiration. [...] Livers from WPI mice had significantly fewer hepatic lipid droplet numbers and less deposition of nonpolar lipids. Furthermore, WPI improved glucose tolerance and insulin sensitivity.

While you are waiting for the human study to be published (the SuppVersity will have it first ;-), get yourself some tasty whey protein and listen to Dr Arciero on Super Human Radio!
