True GRIT is an all new line of health supplements launched in January 2015 by BodyBuilding.Com, the world’s leading online retailer of nutritional supplements and self acclaimed as the most visited fitness site on the web. This review and guide looks at the pre-workout supplement in the True GRIT line (which also includes a whey protein, test booster, post-workout supplement and multi-vitamin) and offers an objective opinion of its effectiveness, value for money and overall appeal.

Claims

BodyBuilding.Com launched their new line of supplements with typical fanfare and bravado. They claim they used clinical studies carried out at leading universities and sports labs to produce a truly unique set of products aimed primarily at high performance athletes. There is however scant information, if any, about the veracity of such hyperbolic claims. BodyBuilding.Com have also specifically labeled their pre-workout supplement the ‘most powerful’ formulation in the market.

Ostensibly, True GRIT pre-workout stimulant works by delivering maximum oxygen and nutrients to the muscles you are working to build in a workout. The key ingredient in this respect is Nitrosigine®, a patented complex of inositol-stabilized arginine silicate. BodyBuilding.com claims that in a clinical study (no details of where and when are provided) subjects who were given Nitrosigine showed perceptible and significant increases in their blood’s mean plasma arginine levels within an hour, indicating highly improved flow of blood to muscles. Please check the section on Supplement Facts where I have elaborated to more detail about the compound Nitrosigine.

Supplement Facts

Each serving of True GRIT pre-workout supplement ( a scoop of roughly 8 grams) provides you with 25 calories from 1 gram of carbohydrates. Other nutritional and health ingredients include:

– 25 mg of calcium

– 5 mg of sodium

– 1.6 g of Beta-Alanine as CarnoSyn®

– 1.5 g of Creatine HCl

– 1.25 g of betaine

– 1 g of Taurine

– 750 mg of Arginine Silicate Inositol (Nitrosigine®)

– 250 mg of Arjuna bark Extract (as Terminalia arjuna)

– 175 mg of Caffeine Anhydrous

– 65 mg of L-Theanine

Substances like caffeine anhydrous, beta-alanine, creatine and betaine are common fare in the formulation of other pre-workout supplements. The same applies for minerals like calcium and sodium. They are all safe to use provided they are included in the right proportions.

Arginine Silicate Inositol (Nitrosigine®)
Nitrosigine® is a patented formulation by Nutrition 21, LLC. It is a complex of bonded arginine silicate and has already received the GRAS (Generally Accepted as Safe) status from the FDA. Though I could not find any evidence to support the immediacy of its effectiveness as claimed by BodyBuilding.com, it is true that a clinical study published in May 2014 in the Federation of American Societies for Experimental Biology Journal (FASEB) did show that Nitrosigine does indeed boost levels of nitric oxide, a key factor in promoting relaxation of smooth muscle in blood vessels, increasing blood flow.

The clinical study quoted above found no adverse reactions or side effects associated with Nitrosigine®. In any case, the side effects should be closely related to those associated with Arginine. These are invariably mild and take the form of abdominal discomfort, bloating and diarrhea.

Arjuna Bark Extract
The Arjuna herb is a plant native to India which has been used for many Millennia in Ayurvedic medicine. Today research has shown that an extract of the Arjuna back (Terminalia Arjuna) has a number of cardiovascular and antioxidant benefits. It improves mood, concentration and allows for better mental focus.

Taurine

Taurine is an amino acid with some sulfur in it. The substance is found naturally in many foods with the highest concentration in meats. It is a blood and heart health agent. It helps neurological development on top of regulating levels of water and minerals in the blood. Some studies have suggested that Taurine combines well with caffeine to improve performance though this has not been proven definitively.

L-Theanine

Also known as Gamma-ethylamino-L-glutamic acid or Suntheanine, L-Theanine is a substance derived from tea leaves. L-Theanine is said to have similar mental boosting properties associated with caffeine but there is scant evidence of this. That said, the substance has no known side effects.

Flavors, Jar Sizes and Price per Serving

True GRIT pre-workout supplement is available in a single 8.69 oz jar size which is enough for 30 servings. You only have a choice of two flavors though: fruit punch and watermelon. The supplement is exclusively sold by BodyBuilding.com for $33.99, equating to a price of $1.133 per serving.

Ratings

It is perhaps unsurprising that True GRIT Pre-Workout supplement is one of the best rated supplements on BodyBuilding.com with an average rating of 9.2 out of 10 (excellent) with a total of 162 reviews at the point of compiling this review. Admittedly, there are at least two dozen other pre-workout supplements with much higher ratings than this but it would have helped if the product was available for sale on other reputable sites in order to get a more objective idea of how users view it.

Verdict

True GRIT pre-workout supplement may only have come to the market in recent days but it is nonetheless causing plenty of buzz in health and bodybuilding forums. A look at its ingredients reveals a solid formulation which brings together essential factors for getting an avid athlete ready to take on a challenging workout. Much has been made about the wonders of Nitrosigine but no one should take all the claims by BodyBuilding.com at face value. It would also have helped if the supplement was available in more diverse flavors but perhaps more will come as the product evolves in the marketplace.
