MAINLINE PERFORMANCE BLEND

MAINLINE is designed for everyone: what we call “everyday athletes.” This includes professional athletes, casual runners who hit the pavement a few times a week, and even those just starting to become more active. MAINLINE provides the essential hydration, performance, and recovery support anyone needs to feel energized, recover better, and build healthy habits. We are the main line of supplements to help you get your feet off the ground and stay consistent on your fitness journey.

Everything you need, nothing you don't. Learn more about our mission.

MAINLINE combines a complete electrolyte profile with clinically meaningful doses of performance and recovery ingredients: creatine (5 g), L-Glutamine (2.5 g), plus vitamins C, D, and zinc. Unlike many competitors, it’s sugar-free, avoids proprietary blends and useless fillers, and focuses on transparent, research-backed dosing rather than stimulants or empty calories. It’s intended as a daily, all-in-one solution rather than a single-purpose, hype-driven product.

Creatine 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 cognitive performance during long sessions. 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.

We included these compounds in MAINLINE because they work synergistically to support strength, focus, and recovery—all essential pillars of sustained performance.

Sodium, potassium, and magnesium are the three key electrolytes in the body, each playing a vital role in maintaining fluid balance, nerve signaling, and muscle function. Sodium regulates blood pressure and fluid levels, potassium supports nerve transmission and heart muscle function, and magnesium is crucial for muscle contraction, relaxation, and energy production. Replenishing these electrolytes prevents cramping, preserves neuromuscular efficiency, and helps sustain both physical and cognitive performance in heat or prolonged activity. MAINLINE’s electrolyte profile is designed to restore what’s lost in sweat and optimize cellular hydration so systems run efficiently.

All vitamins and minerals play essential roles in overall health, but vitamins C, D, and zinc are particularly critical for immune function. 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 communication, and it also plays a key role in hormone regulation, including testosterone and other important hormones. MAINLINE combines these key nutrients with L-Glutamine, which supports immune-cell metabolism and recovery, creating a targeted formula to help your body adapt to training stress and maintain resilience.

Yes, the ingredients in MAINLINE are widely studied, safe, and reccomended for ongoing use at their recommended doses. 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.

Use it right after waking up or before, during, or after training, depending on the goal: pre-workout for creatine maintenance and hydration, intra-workout to replace sweat losses and sustain performance, and post-workout to support recovery. Most users take it daily (morning or midday) to maintain creatine saturation, steady electrolyte balance, support immune and hormone levels, and to experience the supportive effects of the amino acid profile. Consistent use yields the best long-term results.

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