What does the data say about Diet Protein Salted Ca... vs Myprotein Slow-Release...?

Myprotein Slow-Release Casein comes as a 2.5kg powder with 23g protein per 30g serving while the Applied Nutrition Diet Protein arrives in a smaller 450g pack aimed at weight management. The Myprotein product uses micellar casein for slow overnight digestion. In contrast the Applied one relies on whey and includes extra ingredients for fat control. Both score exactly 70.0/100 overall yet the Myprotein edges ahead on effectiveness at 74.0/100 against 70.0/100. The Applied version takes a slight lead on ingredient quality with 70.0/100 compared to 68.0/100.

Bodybuilders who want slow-release protein before bed should grab the Myprotein Casein at £67.64 for its 83 servings and better value score of 82.0/100. Budget gym users after a quick post-workout shake with decent taste will prefer the Applied Diet Protein at £15.00 since it costs just 45 to 50 pence per serving. Those mixing proteins for desserts or recovery shakes lean toward the Myprotein option. People chasing simple salted caramel flavour without chalkiness pick the Applied one every time.

The Applied flavour mixes cleanly in water or milk and leaves no nasty aftertaste. Myprotein works better blended with other powders but some users find it thicker. Check labels carefully because the Myprotein contains soy lecithin and may include gluten egg or nuts. The Applied version uses whey so it rules out anyone avoiding dairy.
