No its not. Research has shown that intestinal gut problems arise primarily due to the speed A1/A2 protein hits the gut when drinking in a vertical position.
Studies using blinds and placebos have shown that the best technique is to place the gullet in a horizontal position and ingest solely A2 protein milk. This will ensure the gut isn't exposed to A1 and also the A2 has a longer time to be absorbed into stomach lining.
Also gone is the old fashioned "glass of milk". Drinking from a plastic mug has shown the hydrocarbons attach to the milk protein molecules so those mugs are out. Best now to use china or fired clay based vessels.
Ideal temperature is 4 degrees - this will ensure the floral grassy notes remain true to the nose which ensures maximum flavour profiles. Too cold and you may as well be drinking ice. Too warm - well that's solely for the Milo.
I am emailing ATM with the hope they will post a Youtube clip with precise instructions on how to best consume this product to get maximum value.
