Hidryte Ebb · The week-before mineral
Some women get it after every meal. For most, it peaks the same week every month — the week before your period, when your jeans stop fitting on a schedule. Ebb is 275 mg of magnesium glycinate built for exactly that week: the mineral your body runs lowest on, right when it's holding the most water.*
Use Ebb through three week-befores. If nothing changes, email us one line — we refund everything, and you keep the bottles. Nothing ships back.
Ebb is 275 mg of elemental magnesium from 2,500 mg of magnesium glycinate — the gentle, absorbed form — built for the week before your period, when your magnesium runs low and everything slows and swells.* Five ingredients. No laxatives, no caffeine.
Magnesium (275 mg elemental, from 2,500 mg magnesium glycinate), hypromellose (the vegetable capsule), rice flour (the filler), magnesium stearate and silicon dioxide (the anti-caking agents). Nothing proprietary.
Three capsules with dinner or before bed, every night. Count back seven days from your expected period — that's the week that matters most, so start your first bottle there. One bottle is one full cycle.
Not overnight — magnesium works with your cycle, not the clock. In the published research, the difference showed in the second cycle, not the first.* That's why the pack is three cycles — and why the guarantee covers all three.
Ships from our US fulfillment center. Free US shipping on the 3-Cycle pack and subscriptions; $4.95 on one-time single bottles. Tracking emailed the day it ships. (We can't ship to Alaska or Hawaii yet — sorry.)
Nothing hurt more than feeling like I lost my own body for a week every month. Ebb gave me that week back.
You're flat when you wake up.
It inflates through the day — worst after meals, or the week before your period.
Some days it just… doesn't happen.
No diet has ever touched it.
These are real, public posts from women describing this week — lightly edited for length, anonymized, and not reviews of Ebb.
Its bloat ingredient is pamabrom — a diuretic — plus an antihistamine. It pulls some of the water. It does nothing about the rest.
Treats: water only
Simethicone breaks up gas bubbles. If your bloat were only gas, it would have worked already.
Treats: gas only
Built to digest a heavy meal. If your bloat only followed pizza, they'd have worked by now.
Treats: food bloat
One formula chasing twelve symptoms — mood, skin, cramps — with your bloat as a footnote. Nobody ever made your bloat the point.
Treats: your bloat last
More diuretics. Same half of the problem, harsher delivery, and the puffiness comes straight back.
Treats: water only
None of them finished the job. Not because you're broken — because they were each built for a different bloat.
Hormonal shifts before your period signal your body to hold on to water and sodium.
Progesterone slows the gut. Things sit, stretch and press outward — the distension you can't suck in.
Most magnesium on the shelf is either poorly absorbed (the cheap forms your body mostly passes through) or deliberately laxative — the citrate powders that "debloat" you by sending you running to the bathroom. Neither is something you can take calmly, daily, the week you already feel at war with your body. And if a drugstore magnesium ever "sort of helped" before it sent you running — you've met the mineral. You just hadn't met the form.
Ebb is 275 mg of elemental magnesium from 2,500 mg of magnesium glycinate — the form bound to glycine, known for being the best-absorbed and least disruptive way to take it. No laxative effect. No caffeine. No dash to the bathroom. Gentle enough for every single day of the month — strong enough for the one week that matters.*
Count back seven days from your expected period. That's your start date. (On the 3-Cycle plan, our Week-Before Reminders do this for you — an email the day it's time.)
With dinner or before bed, every night — through the week and the rest of your cycle. That's the entire protocol. One bottle is one full cycle, and the mineral is in place before the water is.
Same calendar, different week. Less of the overnight swell, less of the can't-button standoff — building cycle over cycle.*
No enzyme blend pretending your dinner is the problem. No diuretic pretending it's only water. No proprietary blend hiding the doses. Read it — that's the whole pitch.
The molecule, yes — and we'll never pretend otherwise; the label is public. What the $13 bottle doesn't come with: the right form at the right dose (many cheap bottles are the laxative form, or a form that's rough on your stomach), the week-before protocol timed to your cycle, the Week-Before Reminders on the 3-Cycle pack that make you actually take it during the week that matters, and a 90-day guarantee from a brand built around this one problem. You're not buying a mineral. You're buying the system that makes the mineral land on the right week — with your money back if it doesn't.
Because they treat different halves of a two-part problem. Midol's bloat ingredient is a diuretic — water only. Enzymes digest food — food bloat only. Magnesium is the one mineral involved on both sides: fluid balance and keeping digestion moving. That gap has a name — the half-treated bloat — and it's the gap everything you tried left open.*
No — and that's the point. Fat and bloat are different problems: fat doesn't arrive overnight and leave by week two. Ebb supports normal fluid balance and digestion around your cycle* — it does nothing to body fat. Any product that promises to handle both is lying about one of them.
Honestly: this works on cycle time, not clock time. Ebb supports normal fluid balance and digestion through the week-before* — the kind of change you compare across cycles, not hours — and in the published research, the difference vs placebo showed in the second cycle. If a product in this category promises tonight, it's a laxative or a diuretic wearing a wellness label. Our guarantee covers three full cycles precisely so you never have to take our word for it.
Citrate is the laxative form — it "works" by pulling water into your bowel, which is the last thing you need that week. Glycinate is magnesium bound to glycine: gentle on the stomach, easy to absorb, no laxative effect — the only form that makes sense to take nightly through your whole cycle.
That's what the protocol is built for — it keys off your expected period, not a perfect 28-day clock. Start when your body's signals (or your tracking app) say you're about a week out; and if the week surprises you, start the night you notice — Ebb is gentle enough for any day of the month. On the 3-Cycle plan, the Week-Before Reminders adjust with whatever dates you give us.
Magnesium glycinate is one of the most-taken, best-tolerated supplements there is, and Ebb is made in an FDA-registered US facility. With other supplements, one honest check: read your other labels so you're not doubling up on magnesium a multivitamin already gives you. And if you're pregnant, nursing, under 18, on medication, or have a medical condition — ask your physician first. That's not legal boilerplate; it's the correct order of operations.
No trap, by design: it's opt-in only (never pre-ticked), the next ship date is always visible in your account, and skip or cancel is one click — no chat window, no phone call, no "retention specialist." We'd rather earn the reorder with your third cycle than trap it with a checkbox.
Buy Ebb, use it through up to 90 days. If your week-before hasn't changed, email support@hidryte.com — one line, no questionnaire — and we refund the full price. You keep the bottles. We can offer that because the window matches the mechanism: three cycles is a real test, and we're betting Ebb passes it.
From our US fulfillment center. Orders typically ship within 2 business days and arrive in about 3–7 business days. (We can't currently ship to Alaska or Hawaii — sorry.) Free shipping on the 3-Cycle plan; $4.95 on single bottles.
No. Anyone reading the front of the bottle learns exactly one thing: you take a mineral. The week-before is your business — the label keeps it that way.
You know the date. This time you can be ready for it — or you can be back in the "that week" jeans, waiting it out again. Three cycles, 90 days, money back. Read the label first. Then decide.
