A new study that indicated identical effects of rice protein isolate and whey protein isolate for sports nutrition shows that rice protein now shares the trophy as sports nutritions protein source of choice, says the CEO of Axiom Foods.

Results of the study indicated that rice protein isolate administration post resistance exercise decreases fat-mass and increases lean body mass, skeletal muscle hypertrophy, power and strength comparable to whey protein isolate.

The studys findings have been submitted to Nutrition & Metabolism and were presented recently by Dr Ralf Jaeger from Wisconsin-based Increnovo LLC, who collaborated on the research with Dr. Jacob Wilson from The University of Tampa.

The rice protein the researchers chose for the study was Growing Naturals Organic Rice Protein made with Axiom Foods Oryzatein.

Groundbreaking

David Janow, Axioms CEO and President, and owner of Growing Naturals, told NutraIngredients-USA: The effects were not just similar between rice and whey, they were identical.

The amino acid profile for rice protein and whey protein is very similar, he said, with differences of 1-3% in some of the amino acids. Rice protein is even better for arginine and glutamine, he noted, while whey is better for the branched chain amino acids (BCAA).

Dr Jaeger added: "From the amino acid analysis you can see that rice protein isolate is not a 'complete' protein (Lysine content is too low) and that THE sports amino acid leucine is lower in rice protein isolate compared to whey protein isolate (8% vs. 11.5%). However, in combination with resistance training at 48g both show the absolute identical results on recovery, body composition (lean body mass, fat free mass, muscle hypertrophy), and ultimately on strength and power (that's the only real thing athletes care about). Both resulted in massive gains."

There is a high correlation to whey and I knew that from a long time ago," Janow told us. "What the new study showed was that the difference in amino acid values is not enough to change the effects, compared to whey.
