The market is broken

Consumers are over-supplemented and under-served.

The functional beverage shelf is crowded, yet nothing actually delivers. People stack low-absorption pills, drink sugar-laden sports drinks, and pay premium prices for wellness water that does little. Ruckgen exists to close that gap.

The problem

The shelf is crowded but nothing delivers: too much sugar, weak doses and wellness gimmicks. Ruckgen exists to close the gap.

Pills

Tablets can be poorly absorbed

Much of a tablet is lost breaking down in the gut, so a lot of what you pay for is never used.

Filler

Many sports drinks underdeliver

Often built around sugar or fillers, with only a fraction of the electrolytes you'd want.

Fatigue

Pill fatigue is real

Stacking tablets every day is hard to keep up, so the results rarely show.

Women

Women are often overlooked

Few on-the-go drinks are designed for women's everyday energy, mood and balance.

Why Ruckgen

Not another hydration drink. A performance system.

Ruckgen is a multi-function ready-to-drink beverage that brings together nutritional science, performance and premium lifestyle design in a single bottle.

The Ruckgen range of four functional drinks
01

A multi-function approach

Hydration, focus, recovery, everyday immune support and women's wellness, brought together in one considered range.

02

Science-led, not just marketed

Formulated at doses informed by published research, by a founder with a Biomedical Sciences background.

03

Built for absorption

A liquid is generally absorbed more readily than pills that must first break down in the gut.

04

More than hydration

Designed to support focus, skin, recovery and everyday wellbeing, not just to quench thirst.

05

Premium, aspirational brand

A design-led brand for the modern, high-performance consumer who expects more from hydration.

06

Built to scale beyond the bottle

A roadmap into smart hydration gear, performance wear and subscription wellness systems.

The science

Seven functional ingredient groups.

A multi-layered formulation approach means Ruckgen is more than a hydration drink, it's a considered system built for everyday performance.

Liquid

Built for absorption. A liquid format designed for absorption, formulated at doses informed by research.

The case for liquid

Why liquid wins.

A liquid is absorbed more readily than pills that must first break down in the gut. The figures below reflect that advantage over typical formats.

0%

Target nutrient bioavailability for Ruckgen's liquid system, versus the ~10–20% typical of pill formats.

0+

Functional actives across the four formulas, each one named and dosed, from CoQ10 and collagen to L-theanine.

0×

Up to five times more of each nutrient absorbed than a typical pill, which loses most before it reaches you.

0%

Functional ingredients, no artificial fillers, junk or synthetic additives.

Figures illustrate the general advantages of liquid delivery over typical pill formats. Full clinical substantiation of formula-specific claims is a pre-launch priority.

Matched to need

One range, mapped to real goals.

Every Ruckgen drink answers a specific consumer concern, making the range intuitive to merchandise and easy to recommend.
