What people say about each flavor
I honestly saw Four Sigmatic coming out with their...
I honestly saw Four Sigmatic coming out with their protein powder and just rolled my eyes because I thought, 'not another protein powder' I literally have tried them all. They sent out a sample in my mailbox and I just tried it with water and ice - the true test of any protein powder and I swear, it's the best I've tasted. First of all, the absence of stevia and sugar alcohols is what makes this so good! There's no overpowering sweet taste you get with stevia. Their use of monkfruit + coconut sugar is so good! I don't get any clumps or anything because I blend with water and ice. I will add greens and berries next time. There is enough fat in here too to really help absorb the fat-soluble vitamins without having to add nut butter or extra seeds. This is a cost-effective plus to this protein blend WITH quality adaptogens (bc I don't trust any other company when it comes to my mushrooms)! Oh, I am so excited to grab a full can!!!! Thanks for the great product FS!
Love at first sip
It's like a decadent dessert. Find myself craving this every day. Amazing creamy peanut butter flavor. Great for breakfast, after workout reward, or anytime snack. Gonna have to stock up on this cause I never want to run out.
PHENOMENAL PROTEIN POWDER!
Four Sigmatic Creamy Cacao Protein Powder is ABSOLUTELY AMAZING! It is not only DELICIOUS, but it is the HEALTHIEST protein powder I have purchased. I LOVE it!! I am on my second order and will continue ordering. I am SO GRATEFUL I found Four Sigmatic . Thank you!
Finally Found the One!
Several decades of searching to find genuine article with plant based protein that actually satiates hunger and helps me feel more able to face the day! Thanks
Only protein I’ve ever finished a full tub.
Only protein I’ve ever finished a full tub. Been ordering for over a year. Love the real peanut butter taste.
The best vegan protein powder
The best vegan protein powder I have found! I bake with it, put it in smoothies, and even just mix with non-dairy milk.
I love this protein so much I got a subscription
I love how chocolatey it is and it is good in the daytime and nighttime to curb my sweet tooth. I love the ingredients and I trust Four Sigmatic products :)
So yummy
This is probably the best vegan protein powder I’ve ever had! The flavor is wonderful and it masks the taste of any crazy veggies u put in your smoothie. I also put it in oatmeal.
Surprisingly agreeable
This was a high quality plant protein. I am unable to tolerate most because the stevia makes me sick but this has zero stevia and monk fruit is much more agreeable. It’s great on its own or I add almond milk and frozen strawberries. A clean product - Four Sigmatic has a great reputation.
