No bloating!

I have a hard time with protein powder causing me to bloat but this brand hasn’t caused me to have that problem. It’s also not chalky and tastes okay.

Great Zero Carb Powder

I love that this was a zero carb protein powder. The vanilla is great for adding into coffee, smoothies, etc and mixes in fairly easily. It does have a strong vanilla flavor but personally, I like it.

Has a great amount of calories but very hard to get it mixed. Also doesnt work great for coffee.
