Isoflex Review | The Best Protein Powders 

Isoflex Review

Isoflex is a protein supplement that has the potential to help you get the maximum results from your time spent in the weight room. In order to get the most out of your workout, it is crucial to give your body the nutrients it needs to recover and grow at the optimal time. Check out this Isoflex review to learn why we don’t have it ranked as one of our Top 10 Best Protein Drinks.

Isoflex is considered the flagship nutritional supplement for AllMax Nutrition. This is the brand that started it all for them.

The Benefits 

  • 100% whey isolate
  • Helps boost your performance
  • Increases muscle growth


What Is Isoflex?

Isoflex is a powder supplement that gives your body the protein it needs after a hard workout. Supplementing protein in your diet can help your muscles absorb the protein and nutrients it needs at the perfect time they need it. Most foods that are protein rich are hard to digest by your body and take longer to show you the results and the recovery you are looking for.

How Does Isoflex Work?

Isoflex works by utilizing 100% whey isolate protein to give your body an easily digestible protein source to help you build lean muscle while recovering quicker than ever. The way protein works is important to understand when trying to find the best protein shake for you. Many protein blends source their protein from harder to digest ingredients, that might be fattier and higher in calories. Whey protein isolate is one of the best protein sources because it is healthy and very easy to digest.

Isoflex Ingredients 

Protein Blend: Isoflex claims to make their protein blend out of 100% whey protein isolate. When looking at their ingredients list we can see that their protein blend is made up of cross-flow, ultra-filtered whey protein isolate, ion-charged particle-filtered whey protein isolate, and alpha-lactalbumin-rich whey protein isolate. This is a good thing because the fewer sources of protein in a blend, the cleaner the mixture. Many different brands try to use multiple sources and make it seem like a positive. In actuality, they are just avoiding spending more money on their product for a higher quality protein source. We like to use high quality blends that are primarily loaded with high quality protein sources, and whey protein isolate is exactly that.

BCAA: Branched chain amino acids can be found in many different proteins naturally. Whey protein isolate has all the essential amino acids you need right inside of it. While that is a benefit of using a high quality protein, additional BCAAs can and should be added to your protein blend. They can heavily reduce your recover time while also supporting increased muscle growth and provide you with the energy you need to push yourself in your workout. If your protein blend does not include additional BCAAs, you should heavily consider buying them and supplementing them separately.

Nutritional Information: In one scoop of Isoflex you can expect to find:

  • Calories: 120
  • Total Fat: 0g
  • Cholesterol: 0mg
  • Total Carbs: 3g
  • Protein: 27g

Isoflex’s nutritional label is pretty impressive compared to most brands we have reviewed. Their calorie content is pretty average but to have no fat, no cholesterol, low carbs, and 27 grams of protein definitely helps their reputation a bit. Combine these nutrition facts with the fact that they use a 100% whey isolate protein blend, you could have yourself a decent protein powder.

Isoflex Conclusion

The bottom line is that Isoflex is a pretty solid all around product, but still not as good as many of the 100% whey isolate protein powders that we have rated. However, it is definitely heading in the right direction. Check out our list of Top 10 Best Protein Drinks for the best protein shakes on the market.
