FREQUENTLY ASKED QUESTIONS

WHO IS THE PERFORMANCE BLEND DESIGNED FOR?

We design elite fuel for the everyday athlete. This includes anywhere from professional competitors, to avid weightlifters, to casual runners, and even those just starting their fitness journey. Our Performance Blend provides the essential hydration, performance, and recovery elements to sustain you in every active pursuit.

Learn more about our mission.

WHEN SHOULD I CONSUME THE PERFORMANCE BLEND?

We recommend taking the Performance Blend once daily in the morning to maintain steady electrolyte balance, creatine saturation, and immune support.

We are typically most dehydrated in the morning after waking, and after intense physical activity. It can be consumed anytime though, or whenever performance, hydration, and recovery are a priority. During periods of intense and extended training, some prefer to take 2 servings per day: once in the morning and once after training.

HOW SHOULD I CONSUME THE PERFORMANCE BLEND?

Mix with 16 oz of cold water for the best experience. Use less water for a saltier & more flavorful taste, or more water for a lighter, more gentle profile.

HOW OFTEN SHOULD I CONSUME THE PERFORMANCE BLEND?

The ingredients in the Performance Blend are widely studied, safe, and recommended for daily use. Creatine, electrolytes, L-Glutamine, and vitamins have extensive safety data in healthy adults. As with any supplement, people who are pregnant, nursing, have kidney disease, or take prescription medications should consult a healthcare professional before use.

WHAT ELECTROLYTES ARE IN THE PERFORMANCE BLEND?

Each serving of the Performance Blend delivers the following:

1000mg of Sodium Chloride (from Himalayan Pink Salt)

200mg Potassium Chloride

80mg Magnesium Malate

Sodium, potassium, and magnesium are three key electrolytes in the body, each playing a vital role in maintaining fluid balance, nerve signaling, and muscle function. Replenishing these electrolytes that are lost through sweat prevents dehydration, cramping, and compromised recovery, while preserving muscular function, and helps sustain both physical and cognitive performance in heat or prolonged activity.

HOW IS THIS DIFFERENT FROM OTHER HYDRATION AND PERFORMANCE SUPPLEMENTS?

Our Performance Blend combines a complete electrolyte profile with scientific doses of Creatine and L-Glutamine, while combining Vitamin C, Vitamin D, and Zinc.

Unlike many other supplements, it’s sugar-free, avoids proprietary blends and useless fillers, only uses natural flavors, and focuses on transparent, research-backed dosing rather than stimulants or trending ingredients. The Performance Blend is a daily, all-in-one supplement solution designed to replace every other product you use.

WHAT DO CREATINE AND L-GLUTAMINE DO?

Creatine is one of the most studied & scientifically validated supplements in existence, primarily researched at a dose of 5 grams per day. It replenishes phosphocreatine in muscle, supporting rapid ATP production during high-intensity efforts. This translates to improved strength, power, and shorter recovery between sets. Creatine also supports brain health and cognitive performance, and is being increasingly recommended by health professionals to older adults for the physical and mental benefits.

L-Glutamine is a conditionally essential amino acid that helps replenish amino acid stores after training, supports immune-cell metabolism, and aids recovery and gut integrity during periods of physical stress. There is also a growing body of research showing L-Glutamine's ability to increase water and electrolyte absorption, showing its synergistic benefits with the Performance Blend's electrolyte profile.

HOW DOES L-GLUTAMINE SUPPORT BETTER HYDRATION?

L-Glutamine supports hydration by helping the body absorb water and electrolytes in the gut and by acting as an osmolyte to enhance cellular hydration. This can make it especially useful during intense exercise or physical stress, helping maintain fluid balance and performance. It also supports gut health and recovery, which can improve overall nutrient absorption and resilience under physical strain.

WHAT ARE THE BENEFITS OF MAGNESIUM MALATE VS. OTHER MAGNESIUM FORMS?

The Performance Blend uses magnesium malate because it’s one of the most effective forms for energy, hydration, and performance.

Unlike other forms, such as magnesium citrate or magnesium oxide that can be harsh on the stomach and have a natural laxative effect, magnesium malate is highly absorbable and often considered the most gentle form. It’s also different from forms like magnesium glycinate or magnesium L-threonate, which are better suited for relaxation and sleep rather than activity and performance.

Magnesium malate also supports the body’s natural production of ATP - the molecule your body uses to create and sustain energy - and can work synergistically with creatine.

HOW DOES THE PERFORMANCE BLEND SUPPORT IMMUNE AND HORMONAL FUNCTION?

Among its many functions, Vitamin C acts as a powerful antioxidant that protects cells from damage and supports the activity of immune cells. Vitamin D regulates immune responses, helps reduce the risk of infections, and is also essential for bone health by aiding calcium absorption and supporting skeletal strength. Zinc is vital for immune cell development, and plays a key role in hormone regulation, including testosterone and other important hormones.

WHAT ARE THE PERFORMANCE BLEND'S COGNITIVE BENEFITS?

Creatine has been extensively studied for its cognitive benefits: it helps increase the brain’s available energy by replenishing phosphocreatine stores, which supports faster mental processing, improved memory, and reduced mental fatigue, especially during intense cognitive tasks or periods of sleep deprivation.

More generally, optimized hydration through balanced electrolytes maintain brain function by supporting nerve signaling and preventing cognitive decline linked to dehydration.

Words From Recurring Customers

"The Only Supplement I Take"

If I had to choose just one supplement, this would be it. It has all of the ingredients I was already taking separately, in one simple drink. That makes it so much easier to stay consistent instead of juggling a bunch of different products. I also appreciate that it’s packed with ingredients that are actually backed by solid research rather than a bunch of filler. The flavor is incredibly refreshing too, and it’s become my favorite thing to sip on during workouts. 10/10.
