Winter is coming

Start before the season does. Not after.

Tonic herbs like astragalus are built for daily consistency, not emergency doses. The people who get the most out of Klara Boost start in the fall and keep going straight through to spring: holiday travel, school germs, short days and all.† Two easy ways to set yourself up for the whole winter.

What you get

What a good day feels like.

You're not really buying drops in a bottle. You're buying more of the days where you feel like yourself: clear, steady and ready for whatever's on the calendar.

Steady defenses

Walk into crowded flights, packed offices and the sniffly season with daily backup from astragalus and echinacea, two of the most studied immune herbs in the world.†

Energy that lasts past lunch

No 3 p.m. crash, no jittery third coffee. Eleuthero and suma help your body keep an even pace from the morning meeting to dinner on the table.†

Calm under pressure

The inbox fills up and the to-do list grows. Adaptogens help your body take stress in stride, so a hard week stays a hard week, not a free fall.†

Sound familiar?

You're not lazy. You're running on empty.

Nobody warns you that being a grown-up mostly means being a little bit tired. If any of these sound like your week, you're in good company.

  • It's 3 p.m. and I've read the same email four times.

Picture tomorrow morning

Here's what ten seconds looks like.

The kitchen is still quiet. You pour your coffee the way you always do, and before the first sip you squeeze in thirty drops of Klara Boost. No pill to swallow, no chalky shake, no alcohol burn. Your coffee still tastes like your coffee.

By the time you grab your keys, you've already done one good thing for yourself today. Six roots are now part of your morning, used the way herbalists always have: a little, every single day.†

Then the day does what days do. The early flight, the deadline, the coworker who really should have stayed home. And you're glad you kept the habit going.

Start tomorrow morning →What's in the six roots?
Inside every drop

Six roots. Each one has a job.

You deserve to know exactly what you're drinking. Every root in Klara Boost has centuries of traditional use behind it and a growing body of modern research. Tap any one to read its full story.

The foundation

Astragalus

Astragalus membranaceus · organic

Taken daily in Chinese tradition for 2,000 years to build resilience over time. If we could keep only one root, it would be this one.†

Astragalus guide The first responder

Echinacea

E. angustifolia root · organic

North America's best-known immune herb, used by Plains nations long before it reached a pharmacy shelf.†

Echinacea guide The steady energy

Eleuthero

Eleutherococcus senticosus · organic

A classic adaptogen, studied for decades for stamina and focus under pressure. Energy that stays level instead of spiking.†

Eleuthero guide The stamina root

Suma

Pfaffia paniculata · organic

In Brazil it's called para toda, "for everything." A traditional Amazonian tonic for vitality and recovery.†

Suma guide The harmonizer

Licorice

Glycyrrhiza glabra · organic

Added to herbal blends for 4,000 years to bring a formula together. It soothes, and it supports a balanced stress response.†

Licorice guide The lymph mover

Red root

Ceanothus americanus · wildcrafted

A North American herb traditionally used to support the lymphatic system, the network that carries waste away from your tissues.†

What to expect

Your first month, honestly.

Herbs aren't caffeine. They're gentle, steady and cumulative, which is exactly why they deserve a real month. Here's how it tends to go.

  1. Day 1

    Thirty drops into your morning drink. That's the whole commitment. No new appointment in your day.

  2. Week 1

    It's automatic now. The bottle lives next to the coffee maker and rides along in your bag on travel days.

  3. Weeks 2–3

    Tonic herbs and adaptogens are traditionally taken daily for weeks. This is the stretch where showing up every morning matters most.†

  4. Day 30

    Your call. Keep the habit, or email us for a full refund. Either way, you gave yourself a fair shot.

Klara Tea · for your evening

The house is quiet. Your stomach can be too.

The dishes are done. You fill the kettle, spoon Klara Tea into your favorite mug and pour. As it steeps, the slippery elm turns the water soft and silky, and the licorice makes it naturally sweet. The whole kitchen smells warm.

Ten minutes later you're on the couch, both hands around the cup, sipping something that soothes on the way down.† No caffeine, so it won't keep you up. No sugar, because it doesn't need any.

It's the part of the day that's finally yours. This just makes it a little sweeter.

The honest comparison

All the roots. None of the trade-offs.

Most immune products make you choose: a gummy with one herb and a spoonful of sugar, or six herbs in a shot of grain alcohol. You shouldn't have to pick.

Questions

Things you might be wondering.

Still deciding? Email info@drink-products.com. A real person answers, usually within a day.

What is Klara Boost?

An alcohol-free liquid herbal supplement made from six roots: organic astragalus, organic echinacea angustifolia, organic eleuthero, organic suma, organic licorice and wildcrafted red root. It's made to support healthy immune function, steady daily energy and the way your body handles everyday stress.† One 1 fl oz bottle holds 30 daily servings.

How do I take it?

Add 30 drops to water, juice, coffee or a smoothie once a day. Most people do it with their first drink in the morning so it becomes automatic.

When will I notice a difference?

Tonic herbs like astragalus and adaptogens like eleuthero are traditionally taken daily for weeks, not days. Give it the full 30-day bottle before you decide. That's exactly why our guarantee runs 30 days.

Can I take Klara Boost and Klara Tea together?

Yes. Klara Boost in the morning and Klara Tea in the evening is the routine we designed them for. Both contain licorice root, so if you have high blood pressure, heart or kidney concerns, or take blood pressure medication, check with your doctor first.

Who should talk to a doctor first?

Check with your healthcare provider before using Klara Boost if you're pregnant or nursing, have an autoimmune condition, take immune-suppressing or blood pressure medication, have high blood pressure, or are allergic to ragweed or other daisy-family plants. Klara Boost is formulated for adults.

Where can I buy it?

Both products ship through Amazon: Klara Boost and Klara Tea. For practitioners, gyms, offices and stores, see wholesale.

Tomorrow morning

Ten seconds. Thirty drops. One good habit.
