The Science
The Formula
BUILT ON
physiology,
NOT HYPE.
Most hydration products are built around marketing. Redi Supplements is built around how your body actually loses and absorbs electrolytes — and what it takes to put them back the right way.
Not all magnesium is equal. Not all calcium is equal. The form of each mineral determines how much your body can actually absorb and use — so we chose the forms that work hardest once they're inside you.
A long day doesn't drain sodium alone — it depletes a specific mix of electrolytes in specific proportions. Dumping any one mineral in isolation doesn't fix that. Our ratios are built to replace the full set together.
Proprietary blends let companies list impressive ingredients without disclosing how little they actually include. We don't use them. Every amount is printed on the supplement facts panel, on every product page, before you buy.
The Foundation
WHAT A LONG DAY
ACTUALLY TAKES.
You lose electrolytes through sweat, but also through everything else a long day asks of you — hours on your feet, skipped breaks, dry air, coffee instead of water. Here's what leaves, and why drinking more water alone doesn't put it back.
When sodium runs low, your body can't hold onto water properly — so even if you're drinking plenty, you'll still feel the drag: cramping, fatigue, and that foggy feeling that creeps in mid-shift.
Think of sodium and potassium as a team. Sodium works outside your cells, potassium works inside them. Together they control how your muscles contract and your nerves send signals. Replace one without the other and you've only done half the job.
Magnesium is involved in more bodily processes than almost any other mineral — including how your body produces energy, recovers after physical effort, and keeps muscles from staying tight. Many people are already running low before the day even starts.
Most people think of calcium as a bone thing. But it's also what tells your muscles to actually contract — every single time. Most hydration products leave it out entirely. We didn't.
Chloride is the other half of salt — it travels with sodium and helps your body hold onto the right amount of fluid. Without it, sodium can't do its job properly. It's the piece most hydration products quietly leave out.
Source Quality
THE DIFFERENCE
is in the form.
Cheap supplements use cheap forms of each ingredient. Redi Supplements uses the versions that your body can actually absorb and use — the ones that work, not just the ones that look good on a label.
Unrefined and naturally mineral-rich, delivering the sodium-chloride pairing the body actually needs — along with trace minerals stripped out of processed table salt. It's the difference between a functional electrolyte and a flavoring agent.
The cheap version of magnesium — magnesium oxide — passes through your body mostly unused. Dimagnesium Malate is paired with malic acid, a compound your body already produces for energy, which helps it absorb more effectively and sit easier on your stomach.
The most common calcium used in cheap supplements requires stomach acid to break down, which means it works far less well on an empty stomach. Calcium citrate absorbs whether you've had a meal or not — so it actually shows up when your body needs it.
We chose this form specifically because it delivers both potassium and chloride in a single compound — the same pairing your body naturally uses to manage fluid levels. It's not just about the potassium number. It's about giving your body the full picture it needs to stay in balance.
Amplify Exclusive
BEYOND
HYDRATION.
Amplify adds three more ingredients on top of the full electrolyte formula — each one chosen because it does something specific for your energy, focus, or recovery. Nothing added for show.
Single-source caffeine hits fast and fades fast. We use two forms: Caffeine Citrate absorbs quickly for immediate onset, while Caffeine Anhydrous releases more gradually. The result is a smoother, more extended energy curve — not a spike that drops you an hour later.
Alpha GPC is a well-absorbed source of choline, the building block your body uses to make acetylcholine — the signal involved in attention, reaction time, and staying mentally sharp when your body is under pressure. Not a wellness buzzword. A real ingredient with a real job.
NMN is a precursor to NAD+, a coenzyme your cells use in the process of producing energy. We use it at 98% purity, because with an ingredient like this, quality and effectiveness are the same thing.
Each stick contains 350mg of caffeine — roughly three cups of coffee. Do not exceed one stick per day, and don't combine it with other caffeine sources. Not for use by anyone under 18, pregnant or nursing, or sensitive to caffeine. If you have a heart condition or take medication, check with your doctor first. Not recommended in the evening.
Want the electrolytes without the caffeine? Replenish is caffeine-free.
Our Standard
TESTED.
VERIFIED. OPEN.
Third-party testing means an independent lab — not us — confirms what's actually in every batch before it ships. It's the only way to know what you're actually getting.
"I spent years as a commercial diver — long days, hard conditions, no such thing as an easy shift. Everything marketed to me was built for the gym, underdosed, or hiding behind a proprietary blend. So we made the one I actually wanted to drink."
