Which Promix Protein Supplement is Right for You?

You’ve plugged your data into the Promix Protein Calculator and now have your ideal daily protein intake. The only question left to answer is, “What kind of protein should I take?” 

As one of only three macronutrients required by the body to perform both basic functions and high-intensity physical activity, the quality of your protein matters. Promix has several protein options that make it simple to meet your daily protein intake needs. The right one for you will depend on your fitness goals and dietary restrictions. Here’s what you need to know:

Whey and Whey Isolate Protein Supplements

Promix grass-fed protein supplements come in three varieties: whey, whey isolate, and casein.

Whether you are looking for a grass-fed protein supplement to meet your daily protein goals between meals or after a workout, whey and whey isolate are fast-absorbing options best for building muscle and improving recovery.

One serving (two scoops) of the Promix Whey Protein Powder delivers 25g of protein and just 1g of sugar, compared to 30g of protein and 1g of sugar in the Whey Isolate Protein Powder. What’s more, our Whey Isolate Protein Powder has been micro-filtered to less than 1g of lactose for fast and easy digestion lactose-intolerant athletes can appreciate. 

Another whey isolate protein option for even greater muscle building and recovery support is Promix Recovery Protein Powder, most effective within 15 minutes after training. For curbing cravings and supporting recovery, consider trying Promix Protein Puff Bars and keto-friendly Whey Protein Puffs.

Casein Protein Supplements

Although also derived from cow’s milk, casein protein is absorbed by the body at a much slower rate, making it the optimal protein supplement choice at night for slow and sustained recovery benefits. Promix Casein Protein Powder contains 25g of protein, 0g of sugar, and is micro-filtered for easy digestion.

Vegan Protein Supplements

At Promix, we believe everyone should have the macronutrients they need to meet their fitness and dietary goals. Up until now, it’s been difficult for vegans and vegetarians to find clean supplements packed with organic protein from plants that taste great and easily meet their protein intake goals.

With 25g of protein in each serving, the Promix Vegan Protein Powder is a highly bioavailable vegan protein powder made from organic Canadian yellow peas that’s both easy to blend and smooth to the taste. Whether you are trying to lose weight, build muscle, or support your high endurance workouts with clean, vegan, organic pea-based protein powder, Promix has the vegan protein athletes like you are raving about. No Artificial Anything, and The World's Cleanest Supplements and Snacks.
