One Scoop for Everyday Athletes
Everyone’s chasing an edge. Whether you train to lift heavier, run faster, recover quicker, focus deeper, or just feel better in your body, you’re chasing improvement. Not just in the gym, but in work, in life, in how you show up daily.
And here’s the truth: your performance isn’t just about your training. It’s about your baseline.
It’s what your body is made of, running on, and recovering with, every single day. That’s where Mainline comes in.
One scoop. Nine essentials. Built to support everything your body does, from the first rep to the last meeting.
What Most Athletes Miss About Performance
When we talk about "performance," most people think about a sprint time or a deadlift PR. But real performance? It’s whole-system output, how well your body and brain can function when you need them to.
And the truth is, most people are walking around underpowered. Not because they’re not trying hard enough, but because their systems are under-fueled.
- You’re sweating out sodium but not replacing it
- You’re taking creatine inconsistently, or not at all
- You’re low on magnesium, but don’t notice until sleep or mood tanks
- You’re low-carb, or active, or both, and burning through key nutrients faster than you can keep up
You’re doing the work. But the foundation? It’s cracked.
The Nine Essentials That Power Your System
Mainline wasn’t built to chase trends — it was built to meet real needs. These nine ingredients are proven to support core systems in your body:
Electrolytes
- Sodium – Critical for hydration, nerve function, and endurance
- Potassium – Supports muscle contraction and fluid balance
- Magnesium – Aids recovery, sleep, and over 300 enzymatic functions
Recovery & Cognitive Support
- Creatine – For power output, muscular energy, and brain performance
- L-Glutamine – Supports gut health and immune system recovery
Immune & Hormonal Function
- Vitamin C – Antioxidant support and immune resilience
- Vitamin D – Hormonal support, bone health, and mood regulation
- Zinc – Cellular repair, testosterone support, and immunity
This isn’t fluff. These are foundational compounds your body demands — especially when you’re training hard, recovering actively, working long hours, or simply chasing longevity and wellness.
Who It's For
We built Mainline for people who do the work — and don’t want to waste time piecing together 6 supplements every morning.
If you're:
- A strength athlete trying to lift heavier and recover better
- An endurance athlete needing hydration and resilience on long sessions
- A weekend warrior who wants better energy and fewer crash days
- A founder, operator, or creative needing clean mental focus
- Or just someone done with the guesswork of “what should I take?”
Mainline is for you.
Why We Chose One Scoop
We didn’t want another shaker bottle. Another pill box. Another overpriced "longevity powder" full of fairy dust.
We wanted something real: a formula you could take every day, without thinking about it, knowing you’re covering your bases.
- It’s fast. Add a scoop to cold water and you’re done in 10 seconds.
- It’s clean. No sugar, no artificial flavors, no BS.
- It’s consistent. Taking the right thing every day > taking the perfect thing once a week.
- It’s proven. Every compound has real data behind it. Nothing is here just to look good on a label.
How It Feels When It’s Working
Customers tell us the same few things, over and over again:
- “I don’t crash in the afternoons anymore.”
- “My recovery feels smoother, I’m not as sore or drained.”
- “I don’t have to think about it. It’s part of my rhythm now.”
- “I used to buy five tubs. Now I buy one.”
This isn’t a pre-workout. It’s not a miracle powder. It’s not trendy.
It’s your daily edge, so you can perform better, train harder, think clearer, and recover faster, without stacking a cabinet full of half-empty tubs.
