Evening all. I've recently started incorporating casein protein into my nighttime routine for that slow-release goodness. The only problem is, it's like trying to drink mud. Seriously, it's so thick it feels like I'm eating a paste, not drinking a shake.

I've tried adding more water or milk, but then the flavour gets super diluted, and it's still pretty gloopy. I've also tried different shakers, even a blender, but the consistency is just... challenging. My current brand is Optimum Nutrition Gold Standard Casein, which tastes decent, but the texture is a killer.

Any tips or tricks from you experienced casein users on how to make it more palatable and drinkable? Should I mix it with something else? Does timing or temperature of the liquid make a difference? I'm open to all suggestions, because right now, it's a chore to get down.

Mate, just use way more liquid than you think you need. Seriously. I use like 500ml of water for one scoop. Shakes it right up. 💪

@PumpChaser, 500ml for one scoop? Wow, that's a lot! Does it still taste okay, or super watered down? 🤔

Alexandoy, try blending it for longer, not just shaking. Or swap water for unsweetened almond milk. Makes a huge difference in texture! 🥛

@AnimalLifter, totally agree on the almond milk! It's my go-to for casein, makes it so much smoother and creamier without the glop. 👍

What I do is add ice cubes and blend. The ice breaks down while blending and adds volume without making it feel thin. Or, mix half casein, half whey. Best of both worlds. ❄️

@Jayne_Scott, mixing casein with whey defeats the purpose of the slow-release. If you want the slow drip, stick to pure casein. For convenience, sure, but not for the specific benefit. Just my two cents. 🙅‍♂️

Here's a trick: mix it about 30-60 minutes *before* you actually want to drink it and put it in the fridge. It thins out considerably after sitting a bit. Seriously, try it. 🤯

@Droz, can confirm this works! I usually make mine right after dinner, leave it in the fridge while I wind down, then it's perfect by bedtime. Less mud-like, more milkshake. 🥛

Are you using a proper shaker bottle with a whisk ball or just a spoon? A good shaker makes a world of difference. Also, add liquid FIRST, THEN powder. Essential! 🤝

@ZenithRogue, yes! And make sure the liquid is ice cold. Cold liquids help prevent clumping and improve mixability for me. 🔥

@ZenithRogue, spot on with the shaker and adding liquid first! That, combined with super cold water and letting it sit for a few minutes, makes it genuinely drinkable. Takes practice but worth it. 💯

Unpopular opinion maybe, but I actually *like* the thickness of casein. Helps me feel fuller longer, especially before bed. Just chug it, it's not meant to be a refreshing drink. 💪

@philosopher, glad I'm not the only one! I actually make mine super thick, almost like a pudding. Eat it with a spoon. Perfect for feeling full all night. No hunger pangs. 🥣

It can also depend on the type of casein. Micellar casein is naturally thicker than, say, calcium caseinate. Check the ingredients, some brands are just inherently gloopier. YMMV. 🤷‍♂️

This might sound counter-intuitive, but sometimes adding a tiny pinch of xanthan gum (like 1/8 tsp) can actually make it *less* thick and more uniform, by improving suspension. Don't overdo it though! Or a few chia seeds can work too. 🤯

Alexandoy, the issue is primarily casein's micellar structure, which forms a gel in stomach acid. For shakes, cold liquid and higher liquid-to-powder ratio are key. Also, some brands use enzymes to reduce viscosity, check labels! 🔬

Honestly, some brands are just inherently less thick than others. If you're really struggling, it might be worth trying a different brand next time. Optimum Nutrition's Gold Standard Casein usually mixes pretty well for me. 💸
