Rule One Proteins was founded in 2014 under the parent company Nutrivo, LLC – the brain trust of Tony Costello Sr. and his son,Tony Costello Jr. Tony Sr is one of the two founders of what is now known as Optimum Nutrition; yes I typed that right, the same company that used to have the best protein on the market. ) Brothers Mike and Tony Costello (Sr.), sold Optimum Nutrition to Glanbia Nutritionals in 2008 for $315 million. They both had intentions of walking away from the sports nutrition supplements industry entirely, but when Tony Sr had the opportunity to start Rule One, and create Rule 1 protein powder; it was something he couldn't pass up. So in creating the number one fitness supplement brand over 22 years, if they were starting over certainly they thought they could create a better version of protein then Optimum Nutrition Gold Standard Whey.
