How it started

One basement. A graveyard of half-used electrolyte tubs. A better answer.

The short version of how Engineered Nutrition got built — and the community it was built for.

EN started in a basement in Watertown, Connecticut, where two people were hand-packing stick packs into orders at a dining-room table. Same table the family ate dinner at the night before.

The product came out of frustration: every electrolyte on the market compromised somewhere — too much sodium and not enough of anything else, 13 grams of sugar per serving, artificial sweeteners, weak dosing, or unverified manufacturing. We tested everything. None of them worked the way our coaches and training partners actually needed them to.

So we built the thing we'd drink ourselves — zero sugar, full-spectrum minerals, dosed by data, tested every batch. Then we sent it to the people we trained next to. Their feedback made the second batch. Their gyms ordered the third. Their coaches recommended it to their members.

Two years later, EN is on the shelves of 100+ CrossFit and functional fitness gyms across the US and Canada, sponsoring the competitions our community actually competes in. Nothing about this brand was built without the community at the table.

Nothing changes unless I change. The basement, the 11 PM packing sessions, the slow first year — that's the cost of building something the right way. — Nino Polletta · Founder & CEO

The problem I built EN to solve.

Hydration is broken at the formula level. The market is full of compromise: some products are mostly sodium and miss the four other electrolytes your body actually loses. Some are loaded with 10+ grams of sugar that work against the workout. Some are weakly dosed and rely on flavor over function. None of them were engineered around what an athlete loses in a hard hour.

I'm Nino Polletta — and I built EN because I'd been training hard, eating clean, drinking water, and still hitting walls every time. Once I started reading labels, the problem was obvious. So I quit a stable engineering career, moved into my parents' basement, and put $150,000 of personal savings into formulating the cleanest, most-dosed, third-party-tested electrolyte stick I could build. One product. No compromises. Built for athletes like me.

What We Stand For

Five values. Named on purpose.

These aren't generic corporate-speak. Each one is a tiebreaker when business decisions get hard — and a filter for who joins this brand and how we treat the people we serve.

Never Compromise — EN circular badge
Value 01

Never Compromise™

Every detail. Every interaction. No cutting formula integrity to lower COGS — ever. Every milligram on the label is exactly what's in the stick.

Average F*cking Sucks — astronaut icon with EN brand mark
Value 02

Average F*cking Sucks

Average brands don't make history. We refuse to look, sound, or compete like every other supplement brand. The bluntness is on purpose.

Be Relentless — runner icon
Value 03

Be Relentless™

You can't beat someone who never stops. That's the motto. "Be Relentless. Never Compromise." is the tagline because relentlessness is the trait — not a slogan.

Grow 1% Every Day — chart icon
Value 04

Grow 1% Every Day

1% × 365 days = 37× improvement in a year. Better content, better customer experience, better product — every day. Failure is fine. Not learning isn't.

Random Acts of Kindness — heart and hand icon
Value 05

Random Acts of Kindness

Net positive in everything we touch. Free product to a customer's kid when he's old enough to train. It's the warmth that makes the relentlessness sustainable.

Why We Built Engineered Nutrition

An engineer's answer to a community's problem.

Athletes are the hero of this story. The villain is bad chemistry. The plot is what happens when a manufacturing engineer reads enough sports-science papers to do something about it.

The Problem

What your body actually loses when you train hard.

Most people think "hydration" = water + a pinch of salt. The biology is more interesting. When you sweat through a serious training session, you're losing a specific cocktail of five electrolytes, in roughly the proportions below. Replace one and miss the rest — you cramp, fatigue, lose focus, and hit walls.

Typical Loss · per liter of sweat
Sodium
800–1,500 mg
Chloride
1,000–1,500 mg
Potassium
150–250 mg
Magnesium
10–30 mg
Calcium
50–100 mg
*Ranges sourced from peer-reviewed sweat-composition research (ACSM, Maughan & Shirreffs). Individual losses vary by genetics, fitness, climate, and intensity.

That's five distinct minerals — not just sodium. Miss any of them after a hard hour, and your nervous system has to ration what's left.

The Status Quo

Every existing product compromises somewhere.

We tested every major electrolyte on the market against the actual biology. Here's what we found:

LMNT
1,000 mg sodium per stick — but only ~200 mg potassium, 60 mg magnesium, no chloride, no calcium. Built for the keto / intermittent-fasting crowd. Athlete-grade for one mineral; incomplete for the rest.
Liquid IV
Up to 11g of sugar per serving. Sugar spikes insulin, which works against fat oxidation and performance. Mass-market hydration, not performance hydration.
Nuun
~300 mg sodium total — underdosed across every electrolyte. Designed for casual hydration. Not enough to replace what serious training depletes.
Gatorade
21g of sugar + artificial dyes + only ~110 mg sodium. Same formulation it's had since 1965. Not engineered for the way humans train today.

Each brand is fine for what it is. None are engineered around what your body actually loses in a hard session.

The Method

How a manufacturing engineer formulates an electrolyte.

Nino Polletta spent 3.5 years at Gillette running production lines, commissioning equipment in Europe, and learning the difference between what's engineered and what's marketed. Then he applied the same methodology to nutrition.

Step 01 · Define

Start with the loss profile

Sweat-composition ranges from peer-reviewed sports nutrition research — not from existing competitor labels.

Step 02 · Specify

Pick bioavailable forms

Magnesium glycinate, not oxide. Citrate forms for potassium and calcium. Forms the body can actually absorb.

Step 03 · Build

Vet the co-manufacturer

Manufacturing-engineer's eye on equipment, GMP compliance, batch traceability — same standard as a pharma line.

Step 04 · Verify

Test every batch, twice

ARL (ISO/IEC 17025:2017) for heavy metals + contaminants. LGC Informed Sport for 250+ banned substances. Every lot.
