ARO Black Series Glutamine Raw Review claims its new Glutamine Raw supplement, will make you “be your best self, in and out of the gym.”

As part of Vitacost’s new ARO Black Series, Glutamine Raw features a “hand-selected ingredient” intended to support workout recovery and fight muscle fatigue.

I looked into Glutamine Raw to see if it’s worth a try.

ARO’s Glutamine Raw Content

Glutamine Raw contains one ingredient: l-glutamine. It is an amino acid that acts as a building block for protein and muscle development.[1]

In addition to building muscle, l-glutamine is proven to improve gastrointestinal health by stimulating mucosal cellular proliferation.[2]

Clinical studies also show l-glutamine strengthens the immune system and is used in many hospitals to help patients heal from trauma and cancer treatments.[2][3]

ARO’s Glutamine Raw provides 5 grams l-glutamine per serving. Clinical studies show this amount is enough to produce results.[4]

Will Taking Glutamine Cause Side Effects?

Glutamine Raw is intended to be taken as a dietary supplement. Mix one scoop with 6 – 8 ounces of your favorite beverage.

Taking one serving of Glutamine Raw daily is within recommended guidelines and is unlikely to cause negative side effects.[5]

However, if you choose to take more than one serving a day, be aware l-glutamine can make liver problems worse and increase the likelihood of seizures.[6]

Is ARO Black Series Glutamine Raw a Good Choice?

ARO Black Series Glutamine Raw provides a good source of glutamine. Glutamine is proven to promote muscle health and enhance immunity.

However, glutamine is pretty cheap to buy. I don’t see how’s Glutamine Raw is better than cheaper glutamine products.

In the end, Glutamine Raw isn’t too expensive and will likely support your exercise goals. However, you might get the same results with a cheaper product.

    Seems to be good. I have a question. I have osteoperosis. Is it safe to take glutamine with this problem?
