What does the data say about Myprotein Slow-Release... vs Casein Protein Powder?
Myprotein Slow-Release Casein 2.5kg beats Dymatize Casein Protein Powder with an overall score of 70/100 against 64/100. The Myprotein version delivers 23g protein per 30g serving from micellar casein while the Dymatize one offers sustained amino acid release from the same form but scores lower on effectiveness at 63/100 compared to 74/100. Both use powder form yet Myprotein mixes better in shakes and desserts thanks to its single thickener of xanthan gum and cleaner profile without extra additives that some rivals include.
Pick Myprotein if you train hard and watch your wallet since it scores 82/100 on value at £67.64 for 83 servings in the 2.5kg tub. Bodybuilders who take it before bed or blend it with whey will like the slow overnight release and budget price. Choose Dymatize instead if you need something between meals and prefer its complete essential amino acid profile with high leucine content even though it scores only 57/100 on value.
Practical matters matter too. Myprotein avoids carrageenan but contains soy lecithin so it does not suit soy-allergic users and may have traces of gluten egg or nuts. Dymatize feels thicker than whey which some dislike and it contains dairy that rules out anyone with lactose issues or milk allergies. Both taste decent when mixed well though neither wins prizes for flavour.
Myprotein Slow-Release Casein 2.5kg uses micellar casein — the gold standard slow-digesting protein form — delivering 23g protein per 30g serving across a generous 83-serving tub.
