  1. Why did Fluid decide to make a whey protein?
    We made this product to be of service to customers we care about and the athletes they serve. We are a customer driven organization, and when our dietitians and strength coaches at the professional and D1 level ask for a clean, simple, whey protein, we listen. While there is no shortage of protein options, there is a void at the intersection of taste, quality, affordability, availability, customer service, and banned substance testing. We have been sourcing premium whey isolate since 2006 for use in our 3:1 recovery drink mixes. Now we are proud to make a stand-alone whey protein option.
  2. Where is the whey sourced from?
    Our whey protein is sourced from grass-fed cows in the UK and Wales that have not been treated with growth hormones or antibiotics. It is GMO & rBGH free.
  3. How and when should I use this?
    • Use after a workout
    • Blend into your breakfast
    • Add to your bedtime routine

Clean Protein That Actually Mixes Well

This is, without a doubt, the best protein powder I’ve ever purchased. As an endurance coach working with young athletes, I understand the critical role protein plays in recovery—especially when we're asking a lot of their bodies week after week. I aim for my athletes to consume at least their body weight in grams of protein daily, and Fluid 100% Whey Protein Isolate makes that goal much easier to reach.

It mixes incredibly well—better than any brand I’ve tried. Even when we didn’t have enough emulsifying mixers at a recent distance running camp, athletes were able to mix it with just a spoon and still get a smooth shake—something I’ve never experienced with other powders. Add in the great taste and the confidence that comes from knowing the ingredients are clean, and it’s clear: this is a product you can rely on.

good clean protein

I’ve been loving this protein. It mixes easily with water which is how I use it for a quick low calorie protein boost before bed. For post run consumption/more calories and carbs I blend it with almond milk and ice or frozen berries sometimes adding a banana and PB powder. It’s delicious. It’s been an effortless way to incorporate more protein into my diet. I’ve been using vanilla for my more complex shakes and the chocolate I’ve only tried with a little water. Both flavors are very good and neither taste artificial.
