FOUR PHASES · 28 SACHETS

A Black woman in a grey sleeveless turtleneck, burgundy leather pencil skirt and red heels crosses a brownstone street holding a takeaway coffee and a closed black umbrella.

Your body changes every week. Your coffee doesn't.

Across a cycle, estrogen rises, peaks and falls, and progesterone climbs and drops. Energy, focus, mood and sleep move with them. Most wellness routines treat every day the same.

Esprevia is built around those shifts. Each blend pairs instant coffee with actives dosed to match human clinical research, matched to your phase, so the cup you already drink every morning works harder for where you are this week.

One base. Four phases.

Every serving starts with the same five actives. Each phase blend then adds what your body needs right now.

Clinical doses. Every active is dosed to match the levels used in published human clinical research, reviewed by a registered dietitian.

How it works

  1. STEP 1

    Start on day one.

    When your period starts, start Relief. Every sachet is labeled with its phase and the days it covers.

  2. STEP 2

    Switch with your cycle.

    Move through Rebuild, Peak and Balance. Cycles aren't all 28 days, so use the ranges as a guide and follow your body.

  3. STEP 3

    Stir, sip, repeat.

    Stir one sachet into hot water or milk, just like any instant coffee. One kit covers one cycle: 28 sachets.

GIVING BACK

Every box helps someone else get through her period.

For every box sold, we donate $1 to a nonprofit that gets period products to women and girls in underserved communities. No one should have to miss school or work because she can't afford pads or tampons.

Questions

How do I know which blend to drink?

Start Relief on the first day of your period. Then follow the days on each box: Rebuild for days 6–13, Peak for days 14–16 and Balance for days 17–28.

Do you ship outside the US?

Not yet. At launch we ship to addresses in the United States only, and founding reservations require a US shipping address. If you're elsewhere, join the waitlist and we'll email you when that changes.

What if my cycle isn't 28 days?

Most cycles aren't, and that's normal. Use the day ranges as a guide. If your luteal phase runs longer or your follicular phase is shorter, adjust. Your body is the final guide, not the calendar.

Can I buy just one phase?

Not at launch, but it's planned. We'll sell each phase blend on its own, so you can build a kit around your own body.

What do you mean by clinical doses?

Each active is included at the amount used in published human clinical studies of that ingredient.

How much caffeine is in each sachet?

We're aiming for 60–90 mg per sachet, about the same as a regular cup of instant coffee. The final amount will be set during formulation.

Isn't caffeine bad during my period?

The research is mixed. Some studies link caffeine to worse PMS symptoms, others find no clear effect on cramps. Most women keep drinking coffee on their period anyway, so we made that cup work harder: every sachet pairs caffeine with L-theanine for calm focus and magnesium, which supports muscle relaxation. If caffeine bothers you, talk to your doctor.

Doesn't coffee block iron absorption?

Coffee's polyphenols can reduce how much iron your body absorbs, so we planned around it. Relief and Rebuild use a form of iron chosen to hold up better in coffee, paired with vitamin C to help absorption. It won't absorb as fully as iron taken alone with water, and that's why we chose the dose with our dietitian.

What happens to my reservation deposit?

It's credited in full to your first Cycle Kit. Deposits help fund our first production run, so they're non-refundable, with one exception: if we haven't shipped Cycle Kits to founding members by July 31, 2027, you can request a full refund. Read the full terms.

Can I drink it on birth control?

Esprevia includes chasteberry (vitex) in every blend, and chasteberry may interact with hormonal birth control and other hormone treatments. If you use hormonal contraception or take any medication, check with your doctor first. They can help you decide if Esprevia is a good fit for you.

Can I drink it while pregnant or trying to conceive?

We recommend waiting. Esprevia isn't designed for pregnancy, breastfeeding or while you're trying to conceive, because every blend contains chasteberry (vitex), which isn't advised during these times. We'd love to have you join us afterward.
