Frequently Asked Questions

Most powders rely on whey alone, which gives you one amino acid profile and tends to upset digestion in larger doses. We use multiple real food protein sources in smaller amounts for a fuller amino acid range that's easier on your stomach. Whey and pea support muscle, chia adds fiber, and collagen supports skin, joints, and bones.

Four real food sources, depending on the flavor: grass-fed whey, pea, chia seed, and collagen. We blend them on purpose, because no single protein covers everything. Together they give a more complete amino acid profile than one source could alone.

It's far less likely to. Most powders use only whey, and a big dose of whey alone is what bothers most people. We use four to five proteins in smaller amounts, plus non-denatured whey with no casein and very little lactose, so even whey-sensitive people tend to do well.

We use organic powdered cream cheese, organic lemon, organic monk fruit extract, and organic vanilla extract to create a tasty flavor that tastes indulgent but still fits the nutritional profile of our other protein flavors (0g added sugar, 25g protein, etc.).

My second favorite flavor

Q&A

How many grams of collagen account for the 20 total grams of protein? Dietician notes it is incomplete protein and doesn’t want me counting it toward my macro allotments.
At Just Ingredients, we value transparency, though some details are proprietary. Since our Protein Powder isn’t primarily a collagen supplement, we typically don’t disclose the exact amount of collagen.
Is this flavor limited edition or is it expected to be around for a while?
Great question! The Lemon Birthday Cake Protein Powder flavor is here to stay! It will be available year round, it is not seasonal.
Will there be a sample for this flavor and the Cookies and Cream?
We are planning on having the stick sizes in the future. Whenever a product is new, it takes a few months for those to be available.
I don’t drink any type of milk. What else can I mix this in? I don’t eat yogurt either.
You can mix this in water!
Is the lemon birthday cake protein gluten free
I am so happy to let you know it is!
