I stopped breathing since I realized air is just chemicals.
Personally I’m always skeptical of anyone who says they need more protein and that the best way to get it is from a shake. I know a good number of road racers and it generally seems to be the 3/4s who rely on the highly processed energy products and the E/1/2 who can be seen drinking milk and eating bananas.
A huge amount of the science behind sports products is done purely to sell the sports products that funded the research.
Recommendations for increasing protein from me include Skyr in place of yoghurt, skimmed milk, Quark, nuts, Jerky/Biltong, just eat more meat, fish (mackerel is a favourite), add some nuts and seeds to muesli for breakfast.
