Isopure Aminos is Nature’s Best latest release.

Isopure Aminos joins a list of already successful supplements, offering a good amount of branched-chain amino acids and also a couple other advantages to those who exercise and train.

Here’s everything you need to know about Isopure Aminos.

The Scoop

Each scoop gives you 5 g of BCAAs (l-leucine,l-isoleucine, and l-valine). Athletes supplement with BCAAs to help post-workout recovery, reduce muscle soreness, and even help positively affect muscle function and development.

The 5 g dose features a 2:1:1 ratio, which is a well-studied ratio, giving you more l-leucine than the other two amino acids. L-leucine is is looked at for its benefits towaringredient profileds protein synthesis in skeletal muscle. [1]

Isopure offers an inflammation-supporting extract of montmorency tart cherries in the form of CherryPure. Tart cherries are supplemented with by athletes to help reduce inflammation as a result of exercise, especially long-distance runners.

Isopure Aminos features brain-supporting and focus-enhancing l-theanine. This ingredient is supplemented with to help improve cognition, whether inside the gym to help support mind-muscle connection or just when you need a little mental boost. A studied amount is 200 mg per serving. [2]

The amount in Isopure Aminos is smaller than the study. Consequently, I’m not sure how strong the effects will be.

Flavor Options

Sick of fruit punch or blue raspberry-flavored supplements? You’ll most likely be stoked on Isopure Aminos’ flavor options. Isopure Aminos comes in 3 flavors –Cranberry Grape, Alpine Punch, and Cherry Lime.

I got my hands on the cranberry grape flavor. It tasted pretty good! It was a sweet flavor, with a little bitterness from the cranberry twist. I mixed a scoop in my shaker cup and tried both 5 ounces and 8 ounces of water.

I much preferred the 8 ounce amount, as the flavor was more subtle, yet still tasty. If you want your flavor stronger, you’ll probably like the 5-6 ounce amount.

I didn’t notice any clumping, though I shook the contents quite a bit throughout my workout before each sip.


I made sure to supplement with Isopure Aminos before and after my leg workouts, and once a day during other workouts.

I also supplement with whey protein. Consequently, my muscle soreness is attenuated. Obviously, I can’t attribute that completely to Isopure Aminos. But, I do believe that Isopure Aminos definitely helped with some of the soreness, especially after my longer leg workouts. I feel like they weren’t as sore as usual.

For those wondering if there are any side effects, I didn’t notice any. There aren’t any stimulants in Isopure Aminos that would cause any serious side effects.

Final Thoughts

A bottle will cost you about $30 and provides 30 servings. Each serving is $1. Considering the additional ingredients in Ispopure Aminos, this price doesn’t seem too bad. However, if you are looking for just a BCAA supplement, you can find much cheaper elsewhere.

Overall though, Isopure Aminos is a good amino acid supplement. If you are looking for an amino supplement with some focus-boosting and anti-inflammatory compounds, don’t count out Isopure Aminos.
