Both protein supplements seems to be particularly rich in EAA including Leucine; which acts as a key amino acid to stimulate the muscle protein synthesis (Dideriksen et al., 2013). It has been estimated that about 0.25g·kg-1 (Witard et al., 2014) up to ~0.40 g·kg-1 (Macnaughton et al., 2016) of high-quality protein providing between ~90 to ~230 mg·kg-1 of essential amino acid (EAA) with 2 to 3 g of leucine (20 to 30 mg·kg-1) consumed after exercise may maximize rates of muscle protein synthesis in young individuals. E.g. for a 70 kg man consuming a typical dose of 20 g of the powder product presented in the table, about 0.23 or 0.26 g·kg-1 of protein would be ingested from 100% All Beef and Whey Isolac respectively. This amount falls within the 90% confidence interval (0.18 to 0.30 g·kg-1) of effective protein dose to promote muscle protein synthesis after exercise (Morton et al., 2015).

Whey isolate provides higher amount of EAA (8.91 or 127 mg·kg-1 vs. 6.82 or 97 mg·kg-1 for a 70kg person) and leucine (1.93 vs. 1.32), respectively. However, despite the aforementioned differences the amount of EAA, including leucine, provided by a 20 g dose of 100% All Beef for a 70kg person would reach a threshold to effectively support muscle protein synthesis and training adaptations in a similar way as Whey Isolac does (Naclerio et al., 2017a, Naclerio and Larumbe-Zabala, 2016). Furthermore other nutritional aspect as the micronutrient composition of the protein sources (e.g. iron, zinc, vitamin B12 or essential fatty acid included in beef) would also represent relevant factors for supporting training outcomes (Phillips, 2012, Naclerio et al, 2017b).
