Plain-language definitions for every ingredient and term on our label and across this site — what it is, what it does, and why it's in the formula.
01
The five minerals every Redi stick is built around. For the full formulation story, see The Science.
Minerals that carry an electrical charge when dissolved in water. Your body uses them to move fluid in and out of cells, send nerve signals, and contract muscles — including your heart.
Sweat is the main way you lose them during a long, hot day, which is why plain water alone doesn't fully replace what the day takes out.
In RediAll five major electrolytes — sodium, potassium, magnesium, calcium, and chloride — in every stick of both formulas.
The main electrolyte in the fluid outside your cells, and the one lost in the greatest amount through sweat. It's central to how your body holds onto water and maintains blood volume.
In RediFrom Pink Himalayan Sea Salt.
The main electrolyte inside your cells. It works with sodium to control fluid balance across cell walls, and it's essential for normal muscle contraction and nerve signaling.
In RediFrom Potassium Chloride.
See also: Sodium
A mineral that helps run more than 300 enzyme systems in the body, including the ones involved in energy production and normal muscle and nerve function. Many adults don't get enough from diet alone.
In RediFrom Dimagnesium Malate.
Best known for bones, but also part of how your muscles contract and your nerves send signals. Many hydration products leave it out.
In RediFrom Calcium Citrate.
The other half of salt. Chloride travels with sodium and helps your body keep the right amount of fluid in the right places. It's also a component of stomach acid.
In RediFrom Pink Himalayan Sea Salt and Potassium Chloride.
02
The same mineral can come in forms that behave very differently in the body. These are the ones we chose, and what we skipped.
Salt mined from ancient sea-salt deposits in the Himalayan foothills. It's mostly sodium chloride — the same compound as table salt — and its pink color comes from small amounts of trace minerals such as iron. We use it unrefined.
In RediThe primary source of sodium and chloride in both formulas.
Magnesium bonded to malic acid, a compound your body already uses in energy production. It's a more soluble form than magnesium oxide — the cheapest option, which dissolves poorly and is absorbed less well than more soluble forms.
In RediOur magnesium source, chosen over magnesium oxide.
See also: Magnesium, Malic Acid
Calcium bonded to citric acid. Calcium carbonate, the cheaper and more common form, absorbs best with food because it relies on stomach acid. Calcium citrate absorbs well with or without a meal.
In RediOur calcium source — a better fit for a drink you might have on an empty stomach mid-shift.
See also: Calcium
"Anhydrous" means "without water." It's caffeine that's been dehydrated into a concentrated powder — the most common form used in supplements and energy products.
In RediOne of Amplify's two caffeine sources. Amplify contains 350mg of caffeine per stick in total — roughly four cups of coffee. One stick per day maximum.
See also: Caffeine Citrate
Caffeine combined with citric acid. By weight it's roughly half caffeine. Once absorbed, it delivers the same caffeine as any other form.
In RediThe second of Amplify's two caffeine sources, counted within the 350mg total per stick.
See also: Caffeine Anhydrous
Short for alpha-glycerylphosphorylcholine, a well-absorbed source of choline. Your body uses choline to make acetylcholine, a messenger involved in muscle control, attention, and memory.
In RediIncluded in Amplify for the focus side of a long shift.
See also: Acetylcholine
A neurotransmitter — a chemical messenger between nerve cells. It's what signals your muscles to contract, and it plays a role in attention and memory. Your body makes it from choline.
See also: Alpha GPC
Short for nicotinamide mononucleotide, a compound your body converts into NAD+. Research on NMN supplementation in people is still early.
In RediA supporting ingredient in Amplify, sourced at 98% purity, alongside the caffeine and Alpha GPC that carry the load.
See also: NAD+
Short for nicotinamide adenine dinucleotide, a coenzyme found in every cell. Your cells use it to turn food into usable energy.
See also: NMN
04
Everything else on the supplement facts panel, and what it's doing there. That's the complete list.
The acid behind the tartness of green apples. Your body also produces it naturally as part of turning food into energy.
In RediAdds tartness to the flavor, and it's the "malate" half of Dimagnesium Malate.
A naturally occurring acid found in grapes and tamarind, used for a sharp, tart flavor.
In RediWorks with malic acid to balance the sweetness.
A zero-calorie sweetener made from the leaves of the stevia plant. High-purity stevia leaf extracts are generally recognized as safe (GRAS) for use in food in the US.
In RediThe reason there's no added sugar in either formula.
A term defined by the FDA for flavorings that come from natural sources — such as fruits, vegetables, or spices — rather than being made synthetically.
In RediReplenish comes in Strawberry Kiwi and Orange; Amplify in Lime Mojito and Mango Pineapple.
A naturally occurring mineral compound — the main component of quartz and sand — used in very small amounts to keep powders from clumping. The FDA permits it as a food additive.
In RediKeeps the powder free-flowing in the stick. It's listed on the panel like everything else.
05
The terms behind how supplements are made, tested, and labeled — and what each one actually covers.
A group of ingredients listed under one combined weight, without the amount of each. It's legal, but it means you can't tell how much of any single ingredient you're actually getting.
In RediNone. Every ingredient and every amount is printed on the panel.
See also: Supplement Facts Panel
The section of a dietary supplement label that lists the serving size, each dietary ingredient, and how much of it is in each serving.
In RediShown in full in the product images on both product pages, before you buy.
Testing done by an independent lab rather than by the brand itself. What it covers depends on which tests are run — microbial safety, identity, potency, or heavy metals, for example — so it's worth knowing what a brand's testing actually includes.
In RediEvery production lot is screened by an independent lab for microbial contaminants.
See also: Certificate of Analysis
A document from a lab reporting the results of tests run on a specific production lot — what was tested, how, and whether it met specification.
In RediOur independent lot testing is documented in COAs from the testing lab.
Short for Good Manufacturing Practices — the FDA's quality rules for how dietary supplements are made, packaged, labeled, and stored, set out in 21 CFR Part 111. They cover facility conditions, equipment, record-keeping, and verifying ingredients.
In RediMade in a facility certified to NSF/ANSI 455-2.
An independent standard for auditing dietary supplement manufacturers against GMP requirements. Certification applies to the facility and its practices, not to individual products.
In RediThe facility where Redi is made holds this certification.

06
Workplace heat-safety terms for crews and the people who run them. Electrolytes are one part of a heat plan — water, rest, shade, and acclimatization come first. Running a crew? See For Crews.
What the temperature feels like to your body once humidity is factored in. High humidity slows the evaporation of sweat, which makes it harder to cool down. The National Weather Service publishes it, and the OSHA-NIOSH Heat Safety Tool app uses it to show risk levels through the workday.
Your body's gradual adaptation to working in heat, typically over 7 to 14 days. Adaptations include sweating more efficiently, losing less sodium in sweat, and working at a lower core temperature and heart rate.
OSHA and NIOSH recommend the "rule of 20 percent" for new workers: no more than 20% of a normal shift in the heat on day one, increasing by no more than 20% each day after. New workers are at the highest risk for heat illness.
OSHA's core message for preventing heat illness at work: drink water often, take rest breaks, and get into shade to cool down.
In RediAn electrolyte drink can be part of the "water" piece on long, hot shifts. It doesn't replace rest, shade, or an acclimatization plan.
