Betancourt Nutrition The Beef Standard
Harness the power of meat proteins
THE BEEF STANDARD is what its name implies; it is the new standard in beef protein supplementation. In a market where claims for beef protein products will be similar, the question will be: what is the diff erence in quality between one beef protein versus the next?
Harness the power of meat proteins with BeefISO™ HYDROLYZED BEEF PROTEIN ISOLATE. Athletes around the world know that you have to eat meat to grow. Now you’re able to get the power of meat in the convenience of a powder.
The BEEFISO™ difference
BeefISO™ beef protein isolate (BPI), with essential metabolic proteins, is the only beef process of BPI that is recognized by the United States Department of Agriculture (USDA). Some of the key diff erences of BeefISO™ include:
- Contains natural creatine and vitamins that are only found in beef
- Fast and easy absorbing
- Over 98% pure proteins
- Easy to digest, high in essential amino acids and low in calories
- Major allergen-free
BEEFISO™ and protein synthesis
Protein supplementation following resistance training leads to greater increases in lean body mass and strength.1 The intake of protein stimulates net muscle protein accretion during acute post-exercise recovery. Serious and smart lift ers know that protein supplementation is required to maximize the adaptive response of the skeletal muscle to prolonged resistance exercise training.
The mammalian target of rapamycin (mTOR) pathway is crucially involved in protein synthesis2 and biological function, impacting nutrient availability , metabolism and DNA repair— ultimately aff ecting cell growth and proliferation, angiogenesis, bioenergetics and survival. 4 Research shows that mTOR phosphorylation, or activation, is associated with the activation of the mTOR pathway and ultimately, protein synthesis.3 This is one road that leads to greater muscle growth, and THE BEEF STANDARD can help you get there.
Five times faster mTOR activation
Western blot is a widely used analytical technique used to detect specifi c proteins in a sample of tissue, and is a semi-quantitative measure of phosphorylated mTOR activation. BeefISO™ has demonstrated fi ve times faster mTOR activation than WPC80, or whey protein concentrate containing not less than 80 percent protein. BeefISO™ shows the highest mTOR activation at 10 minutes poststimulation, and BeefISO™ increases mTOR activation over time. Additionally, BeefISO™ activates mTOR phosphorylation throughout the entire cell.
Beef protein is better
While consuming moderate amounts of whey and animal-derived protein has been shown to improve short- and long-term protein balance over a placebo-matched control, Sharp et al.5 compared high-quality beefbased protein supplementation with whey-based protein sources following resistance training. The researchers wanted to determine the eff ects of post-exercise consumption of two servings of BeefISO™ or whey, compared to a maltodextrin control, on lean mass and strength during eight weeks of resistance training.
In the above study, 30 college-aged, resistance-trained males and females were randomly assigned to one of three groups. Subjects consumed two servings (46 grams) of BeefISO™, whey protein isolate or maltodextrin. Subjects trained fi ve days per week (three days of resistance training, two days of cardio) for eight weeks. Two servings of protein were consumed immediately following exercise, or at a similar time of day on “off ” days. Dual emission X-ray absorptiometry (DEXA) was used to determine changes in body composition. Maximum strength was assessed by one-rep maximum (1RM) for bench press (upper body) and deadlift (lower body).
Both beef protein isolate and whey protein isolate each lead to a signifi – cant increase in lean body mass (5.7% and 4.7%, respectively), compared to baseline. Fat loss also signifi cantly decreased at eight weeks, compared to baseline, for beef protein isolate and whey, at 10.8 percent and 8.3 percent respectively. 1RM in the deadlift and bench press signifi cantly increased for all groups, compared to baseline.
The researchers concluded, “The results of this study further support the benefi ts of protein supplementation following resistance training. Specifi – cally, in this study, consumption of two servings of beef protein isolate or whey resulted in signifi cant gains in lean body mass over time, which outpaced gains resultant from resistance training alone (maltodextrin supplementation).
“Overall, the results of this study demonstrate that consuming two servings of either beef protein isolate or whey protein isolate following resistance training lead to signifi cant increases in lean body mass and strength.”
