SODIUM

Sodium is an essential electrolyte that regulates fluid balance, supports cellular hydration, and enables optimal nerve conduction and muscle contraction — particularly critical during intense physical activity.

POTASSIUM

A intracellular mineral that works in tandem with sodium, potassium is a vital electrolyte that helps to maintain proper hydration, support cardiovascular function, and prevent muscle cramps by regulating nerve signaling.

MAGNESIUM

A cofactor in over 300 enzymatic reactions, magnesium is an electrolyte that plays a key role in overall hydration, energy production, neuromuscular function, and stress regulation, contributing to improved recovery and mental resilience.

CREATINE

One of the most researched supplements in science, creatine enhances cellular energy (ATP) production, improves high-intensity power output, enhances cognitive performance, and supports lean muscle development over time.

L-GLUTAMINE

The most abundant amino acid in the body, L-glutamine supports muscle recovery, immune system function, and gut integrity — especially important during periods of physical stress or exertion.

VITAMIN C

A powerful antioxidant that supports immune defense, collagen synthesis, and protection against oxidative stress — particularly beneficial for active individuals or those under physical strain.

VITAMIN D

Crucial for immune modulation, bone density, and hormone regulation, vitamin D also contributes to mood stability and physical performance, especially in those with suboptimal levels.

ZINC

An essential trace mineral involved in immune response, enzymatic activity, and hormone regulation. Zinc also supports cognitive function and recovery from physical exertion.

Xavier M.

"I’ve been looking for a supplement that combines creatine and electrolytes for a while. Great to see someone combine these two as these are the supplements I value more than the others. Easy to remember to take too. Feels like i have an unfair advantage."

Drew W.

Verified Buyer

“The vitamins in mainline are a nice touch. I usually just take a bunch of vitamin pills with my creatine every morning, but now i don't have to ”

Jack P.

Verified Buyer

“My favorite supplement these days, but honestly i like the light sweet flavor the most. It’s not too much so it doesn’t get old like other powders do. Easy to drink every morning."

THE ANTI-STACK

WE WERE TIRED OF THE WILD WEST OF THE HEALTH & FITNESS SPACE.

As active lifters and runners, we were dialed into our health, but the supplement industry left us feeling utterly lost. Between the creatine, electrolytes, vitamins mixtures, and everything else, we were taking a dozen scoops from a dozen jars just to hopefully feel and perform at our best.

We were tired of the confusion of what to take, the ambiguity of what actually mattered, and the hassle of juggling so many bottles. We were tired of false promises.

SO WE MADE ONE THAT DID IT ALL.

After 10+ years of trial and error with every supplement and nutraceutical under the sun, we slowly fine-tuned the combination that actually made a difference. The stuff that truly helped us lift stronger, run longer, recover faster, think clearer, and feel more dialed-in, every day.

We created our performance blend initially just for us, as a fool-proof way to get in the fitness compounds, minerals, and nutrients we wanted.

THAT'S HOW MAINLINE WAS BORN.

We felt the best we had in years and we never skipped a beat, so we knew we had to share our blend with friends and family. Then we never looked back.

It's the one supplement we wish we had years ago: high-performance ingredients, no fluff, no guesswork. Just everything we actually need, in one simple scoop. Our goals were straightforward — to look good, feel great, and perform at our best daily - and we made MAINLINE to help us do just that.
