Our Ingredients

We have connected with the best manufacturers in the game and strive to create the greatest products possible for every tennis player, no matter what level you are.

The following is a list of some our favorite ingredients that we use along with some helpful information to help you understand some of the science and value behind them:


Caffeine + L-Theanine


Imagine you wake up in the morning, begin your routine, and have a hot cup of coffee to jumpstart your day. Things are going well, but suddenly you feel a bit jittery and anxious.

Your heart is fluttering, you feel euphoric, but it’s also a little hard to focus on the task at hand. Here is the reality…

There are negative side effects of caffeine… by itself.

What makes L-Theanine and caffeine so great together? Synergy.

Caffeine is great for concentration, improving attention, and focus. The downside is increased heart rate, blood pressure, and anxious / jittery feelings. L Theanine is a relaxant that can reduce heart rate and blood pressure [1], promote alpha brain waves (associated with relaxation) and provide balance for the brain to avoid jitters.

But combined, caffeine and L-theanine work better together.

You can concentrate on your work more thoroughly, be more creative, and achieve more success with the absence of headaches, crashes, and anxiety. The combination gives you the power to perform better than taking either alone.

“…suggests that L-theanine and caffeine in combination are beneficial for improving performance on cognitively demanding tasks.” (Journal of Nutritional Neuroscience, 2008) [2]

Coconut Water Powder


For thousands of years, tropical cultures have enjoyed the nutritional and thirst-quenching benefits of coconut water. Our Coconut Water Powder celebrates the ancient tradition, but is designed for modern on-the-go hydration. Each serving provides key electrolytes that support rapid hydration. 

Beta Alanine


Beta-alanine is technically a non-essential beta-amino acid, but it has quickly become anything but non-essential in the worlds of performance nutrition and bodybuilding. It has become a shining star due to claims that it raises muscle carnosine levels and increases the amount of work you can perform at high intensities.

Beta-alanine is also famous for producing a certain "tingle" you probably felt—and possibly freaked out about—the first time you tried a pre-workout supplement containing beta-alanine. Our dosing of beta-alanine is usually low enough that this harmless side-effect won't even be experienced.

Supplementation with beta-alanine has been shown to increase muscle carnosine concentrations by up to 58 percent in just four weeks, and 80 percent in 10 weeks.

What's so special about carnosine, you ask? Well, aside from being a potent antioxidant, this peptide is one of your muscles' first lines of defense against the buildup of hydrogen ions (H+) during high-intensity exercise. This rise in H+ dramatically lowers the pH within muscle cells, negatively affecting enzyme function and muscle excitation-contraction coupling events that support continued, high-intensity output. Put simply, a drop in muscle pH is a major contributor to muscle fatigue.

BCAA (Branch Chain Amino Acids)


BCAAs are the essential amino acids leucine, isoleucine and valine, which comprise around 35% of your body’s muscle protein. They’re “essential” because your body doesn’t make them on its own—you have to get them from food and workout supplements. Like other amino acids, they’re the building blocks of protein. But these particular aminos may also help preserve muscle glycogen stores, which fuel your muscles and minimize protein breakdown during exercise. Translation? BCAAs can help you get more out of your time on the court.

BCAAs fuel your skeletal muscles during training, which can help give you the edge you need to push your limits. Supplementing with BCAAs helps preserve your stores of glycogen—the primary fuel your muscles use for energy production. This means your body has a reliable energy source to tap into while you play, which can keep you going. Plus, abundant glycogen stores keep your body from breaking down muscle protein for energy instead. That’s why BCAA supplements are a win-win for your muscles—they help sustain and safeguard them. That’s potentially more energy, more reps on or off the court.
BCAAs can also help enhance muscle protein recovery after your match or practice, especially when you consume them with carbs. 

Rhodiola Rosea


Rhodiola (Rhodiola Rosea), sometimes called Arctic root or golden root, is considered an adaptogenic herb, meaning that it acts in non-specific ways to increase resistance to stress, without disturbing normal biological functions. The herb Rhodiola rosea grows at high altitudes in the arctic areas of Europe and Asia, and its root has been used in traditional medicine in Russia and the Scandinavian countries for centuries and is still widely used in Russia as a tonic and remedy for fatigue, poor attention span, and decreased memory.

As for rhodiola extract benefits, a 2002 review in HerbalGram, the journal of the American Botanical Council, reported that numerous studies of rhodiola in both humans and animals have indicated that it helps prevent fatigue, stress, and the damaging effects of oxygen deprivation. Evidence also suggests that it acts as an antioxidant, enhances immune system function, and can increase sexual energy.



L-Tyrosine is an amino acid produced within the body from a variety of dietary sources. Its primary roles are protein synthesis and maintaining healthy brain chemistry by providing the material from which dopamine, epinephrine, and norepinephrine are produced. These three vital neurotransmitters have a profound effect on energy levels, mood, motivation, and cognitive function.

Though L-tyrosine doesn’t directly stimulate the production of these neurotransmitters, it does provide a “buffer” of the raw material the brain needs to produce them, particularly beneficial when stress has depleted their levels.

There is robust evidence for the effectiveness of L-tyrosine supplementation, particularly regarding cognitive enhancement, mood and motivation improvement, and mitigating the effects of stress on the mind. 

A 2015 review of more than a dozen studies found that tyrosine loading effectively offset working memory and information processing deficits created by environmental stressors such as extreme weather or extreme cognitive demand. The review speculated that this effect might be explained by the fact that tyrosine provides a “buffer” of raw material from which the brain can produce neurotransmitters, effectively neutralizing the depletion that stress creates. The review concluded that there is evidence that healthy individuals exposed to demanding situational conditions may benefit from supplemental L-tyrosine.

A 1999 military study of cadets on a combat training course showed that a week of L-Tyrosine supplementation significantly lowered systolic blood pressure. The participants receiving L-tyrosine also performed better on memory and tracking tasks than those receiving a placebo.

Sleep-deprived individuals receiving supplemental L-tyrosine performed significantly better at a variety of cognitive and psychomotor tasks than a similar group which was given placebo in a 1995 study.
