Trace

Fasting Hydration

The crash isn't the fast. It's the minerals. Trace puts back the sodium, potassium and magnesium a fast flushes, with betaine for hydration inside the cell. Zero sugar. Won't break your fast.

Benefits*

  • Replaces the sodium, potassium and magnesium a fast flushes*
  • Supports steady energy and hydration while you fast*
  • Betaine supports hydration inside the cell*
  • Zero sugar, zero calories. Won’t break your fast.
What is Trace

Trace is the electrolyte load for fasting: 1,000 mg of citrate-buffered sodium with potassium, magnesium, and 2,500 mg of betaine for hydration inside the cell. One stick in a litre of water, sipped through the window. Zero sugar: it won’t break your fast.

Who's it for

Adults who spend real hours in the fasted state.

  • Committed fasters: 16:8, OMAD, and extended windows, where the mineral gap actually shows up.
  • Keto & low-carb: lower insulin means faster sodium loss, fasting or not.
  • GLP-1 users: smaller appetite often means less incidental sodium and fluid. Trace helps cover the gap.

Not for children, and check with your doctor first if you follow a sodium-restricted diet or manage blood pressure.

Ingredients

Per stick: sodium 1,000 mg (Redmond Real Salt®, sodium citrate), potassium 200 mg (potassium citrate), magnesium 60 mg (magnesium citrate), betaine 2,500 mg (BetaPower®). Real citrus, stevia, and monk fruit. No sugar, no maltodextrin, no artificial colors or flavors.

How to use

Tear one stick into 750 ml to 1 L of water. Sip it through your fasting window, not all at once. Up to two sticks on longer fasts or heavy-sweat days. Naked (unflavored) is the strict-clean-fast option.

Quality & certifications

Made in the USA in a cGMP-registered facility. Every batch is third-party tested for heavy metals, with a certificate of analysis. Non-GMO, gluten-free, vegan. Nothing that breaks a fast.

Fasting-safe

Zero sugar, zero calories, nothing that spikes insulin. Made to drink straight through your window.

Supports cellular hydration

Osmolyte Betaine supports fluid balance both inside and outside the cell.*

Engineered by fasters

Built by people who fast and dosed for what a fast depletes, not what you sweat.

Research-backed ingredients

Forms and doses grounded in published science of fasting physiology.

Mechanism · hours 0-24

Replace electrolytes depleted during fasting.

When you fast, your kidneys flush sodium and water, with potassium and magnesium close behind. That mineral gap is the wall most fasters hit: the headache, fatigue, fog and cramps people call the fasting flu.

Take your fast further.

2,500 mg of betaine per stick. The osmolyte supports fluid balance inside the cell, not just the space around it. We use BetaPower®, a naturally sourced beet form chosen for purity and consistency.*

Benefits supported
  • Cellular fluid balance*
  • Hydration that lasts the window*
  • 2,500 mg betaine per stick

Citrate-buffered magnesium selected for easy absorption on an empty stomach through a long fasting window. Supports healthy muscle and nerve function and the steady energy a fasted body runs on.*

Benefits supported
  • Gentle on an empty stomach
  • Muscle & nerve function*
  • Steady energy through the fast*

1,000 mg of sodium per stick, the electrolyte a fast depletes first. We source it from Redmond Real Salt®, an ancient sea salt mined from an untouched Utah deposit, never lab-blended sodium chloride, so it carries the trace minerals a refined salt leaves behind.*

Intracellular hydration

Electrolytes govern the water outside your cells. To hold water inside, cells rely on osmolytes. Trace supplies both: citrate-buffered minerals for the fluid around your cells, and 2,500 mg of betaine, an osmolyte that supports cellular fluid balance*, for the water within them. Most electrolyte mixes only do the outside.

Trace is the fasting-first electrolyte.

Trace matches the category mineral ratio, then does what a sweat-first formula can't: work with your fast.

Questions

The things fasters ask first.

Straight answers on fast-safety, dosing, and that 1,000 mg of sodium.

Will Trace break my fast?

No. Trace has zero sugar and no meaningful calories, and nothing that spikes insulin. It's built to be taken through your fasting window. For a strict clean fast, reach for Naked, the unflavored version.

Isn't a pinch of salt enough?

Salt covers sodium, but fasting also depletes potassium and magnesium: the minerals behind cramps, fatigue, and poor sleep. Trace gives you all three in the ratio your body loses them, buffered so it's easy to sip.

Is that much sodium right for me?

1,000 mg replaces what fasting actively flushes, sipped over hours rather than taken at once. It's a meaningful dose meant for fasting, low-carb, and higher-need days, not casual, unlimited use. If you follow a sodium-restricted diet or manage your blood pressure, talk to your doctor first.

What is betaine, and why is it in here?

Betaine (as BetaPower®) is an osmolyte: a compound your cells use to help hold water. Electrolytes support hydration around your cells; betaine supports it inside.* It's the part a salt-only formula is missing.

Daily Fast or Heavy Need: how much do I use?

One stick a day covers a normal 16:8 or OMAD window. For a longer or extended fast, or a heavy-sweat day on top of fasting, use up to two.

Is it keto and low-carb friendly?

Yes: zero sugar, no maltodextrin, fast-safe. It fits keto, low-carb, and GLP-1 routines as naturally as it fits fasting.

  1. The natriuresis of fasting: as insulin falls during a fast, the kidney reabsorbs less sodium, so sodium and water excretion rise. Sigler MH, J Clin Invest 1975;55:377. DeFronzo RA, Diabetologia 1981;21:165.
  2. Potassium and magnesium contribute to normal muscle and nerve function and to fluid and electrolyte balance.
