This protein is so yum, you can make it as a hot chocolate, add it to your oats. It is so versatile and delicious. Perfect for on the go, or at night before bedtime. Even tastes delicious with just water. Yum!

I enjoy shopping at vitasave.ca because they always have great prices on top quality supplements. I was so excited when I saw that they were selling Rule One Casein - Vanilla Creme 4 lbs, because I know that this is a high-quality product. I am really happy with the results that I've seen since starting to use it.

I take this before I go to bed, and I feel great when I wake up. It has a really good flavor, and it mixes well with water or milk. I would definitely recommend this to anyone looking for a good casein protein supplement.

16 December 2021

I take this before bed and it mixes well with almond milk. I've only ever tried the chocolate flavour but the vanilla is very good as well. There's no gritty texture and it doesn't leave a weird film in your mouth like some other powders do. The price is also unbeatable compared to similar products on the market.

My wife has been using this product for a while now and she loves it! She has tried other brands but always comes back to Rule One because it just seems to work the best for her. The flavor is great and it mixes easily into any beverage. We will definitely be buying more in the future!

My wife has been using this product for a while now and she loves it. I have to say, it really does help her build muscle and recover quickly from her workouts. This product mixes easily with water or milk and has a really good flavor - not too sweet, not too bland. Overall, I highly recommend this casein protein powder!

Cant beat the taste of this casein. Goes amazing in mug cakes and overnight oats. Usually go for cookies and cream as that is the GOAT flavour but choc is a close second

The flavor is actually good. It mixed okay not great, but that is expected with Casein. It does leave me gassy the next morning, but other than that, it is pretty fair.
