ARO Black Series Glutamine Reviews

ARO Black Series Glutamine

ARO Black Series Glutamine is intended to minimize workout recovery time.

Theoretically, supplying tired muscle with glutamine decreases fatigue and allows it to rebuild faster.

In addition, ARO Black Series Glutamine ads claim it positively affects muscle metabolism. Allegedly, it even improves digestive health.

But, ARO Black Series Glutamine only has one active ingredient. Can this one ingredient produce all these benefits? I researched ARO Black Series Glutamine to find out.

ARO Black Series Glutamine: The Ingredient

ARO Black Series Glutamine’s one potent ingredient is, no surprise, glutamine. Glutamine is an amino acid abundantly stored and produced by the body. [1]

Unlike some amino acids, glutamine isn’t strongly associated with muscle building. When taken before exercise, glutamine produces no effect on weightlifting power. [2] When taken after exercise, as recommended with ARO Black Series Glutamine, glutamine fails to increase muscular protein creation. [3]

On the positive side, glutamine is linked to enhancing muscular storage of glycogen, an energy-holding molecule. [4] Similarly, glutamine taken with carbohydrates is known to reduce ammonia buildup during endurance exercise. [5]

What about ARO Black Series Glutamine’s alleged additional benefits to digestive health? That claim likely arises because glutamine protects gastrointestinal tract lining. Consequently, sometimes people with digestive disorders take glutamine, but clinical trials show it’s ineffective. [1]

Unfortunately, it seems adding glutamine to your diet doesn’t have many noticeable effects. Consequently, it’s probably not an excellent post-workout recovery ingredient.

ARO Black Series Glutamine: The Side Effects

Although glutamine doesn’t have remarkable benefits, it doesn’t usually cause major side effects. For the most part, glutamine is considered safe at doses less than 40 grams per day. [6] ARO Black Series Glutamine recommends doses well below that number.

However, some people should still avoid glutamine. Pregnant and breast-feeding women are better off avoiding it because research doesn’t clearly indicate is effects. People with severe liver disease or who experience mania or seizures should also not take glutamine. [6]

ARO Black Series Glutamine: The Price

Vitacost.com, the maker of ARO Black Series Glutamine, is the only website selling this product. The price is $14.99 for a 30-serving tub, or $11.99 when it’s on sale.

Per serving, ARO Black Series Glutamine is pretty cheap: just under $0.50. It’s pretty hard to find a post-workout supplement with a lower cost per serving. Of course, glutamine isn’t a proven ingredient, so that value is conditional on customer satisfaction.

ARO Black Series Glutamine: The Directions

ARO Black Series Glutamine comes in powder form. Get a glass of water, about 6 to 8 ounces, and mix in 1 scoop powder.

The product label isn’t clear on when to take ARO Black Series Glutamine. But, since it’s a muscle recovery supplement, it’s probably meant to be taken just after working out.

ARO Black Series Glutamine: The Reviews

ARO Black Series Glutamine has only been available since May 2013. That short time frame means it hasn’t gained either a positive or negative reputation among consumers. Plus, no one who’s purchased it has left any comments or ratings on Vitacost.com yet.

Regrettably, this lack of reviews doesn’t make it easier to judge ARO Black Series Glutamine’s value. As product reviews become available for ARO Black Series Glutamine, they’re worth a look.

ARO Black Series Glutamine: The Verdict

ARO Black Series Glutamine hinges its efficacy entirely on glutamine. Unfortunately, glutamine research doesn’t prove it enhances post-workout muscle recovery. In fact, most glutamine studies show it has little to no impact on exercise. Even though it’s inexpensive, ARO Black Series Glutamine isn’t a very good value.
