 January Р2018
– Recently, a product called Native Whey was introduced to the dietary supplement market
– Because of the widely known anabolic effects of leucine on muscle protein metabolism, Native Whey has been considered a higher quality protein supplement as it relates to supporting training-induced muscle growth
– However, despite these purported effects, the scientific literature concerning Native Whey is at the moment very limited
STUDY:
– Hamarsland et al. 2017 provides some insight as to the effects of Native Whey intake post-resistance exercise on muscle protein synthesis (MPS)
– Following resistance exercise, subjects consumed Native Whey, Whey Concentrate, or Milk and MPS was measured up to 5 hrs post exercise
– Native Whey raised plasma leucine content 40% greater than whey concentrate
– However, the rise in post-exercise MPS was similar between the 2 whey protein treatments suggesting that both whey products produce comparable anabolic effects in muscle
– Key limitations of this study included a lack of measurement for protein breakdown to deduce total protein balance and of course the limited translation of acute effects to long term outcomes in lean tissue
