Great customer service

Polite and quick customer service. Wonderful product as well, I have it everyday.

Valerie R.

By far the best product out there

My focus level has significantly improved after 7 to 8 weeks of use. More important for me, sleep has been getting better.

Cathy M.

Easy breezy

Delivered on time. I like the idea of multiple pills. Day for focus, night for sleeeeep.

Jill C.

Tastes good

Lemonade tastes good.

If you own the morning, you will own the day. Feel in control again. Three steps. Two minutes.

You don’t need a big new routine. You need two minutes before the day gets loud. Three simple steps, every morning. You’ll feel the ripple effect in your day.

Step 1

Gulp! With the Brain and Focus Formula

Two capsules. No jitters. No crash. This is your foundation.

Step 2

Hydrate! With the Electrolyte Blend

Your brain is 73% water. Water needs minerals that tap and bottled water simply don’t have enough of. One scoop fixes that.

Step 3

Breathe! It's Free!

Breathe in for 4 counts, hold for 4, out for 4, hold for 4. Four rounds.

Most people see consolidated, longer term results after 8-10 weeks. If you’re dehydrated or deficient in certain minerals, you will see results faster. Pair this method with a balanced diet and drinking enough water. Aim to drink 25oz (750ml) per 50lbs (23kg) of bodyweight. Add 16oz (500ml) per 40 min of working out. This is not medical advice. Results can vary. Consult your doctor.

Same you. Two different paths.

which one are you?

If nothing changes

  • Today you felt foggy by the afternoon. So does tomorrow, and the next day...
  • Sleep isn’t really restful, if you ever catch 8 hours of sleep.
  • Another coffee gets you through, but your energy crashes after a few hours.
  • The little moments keep slipping by while your mind is somewhere else.
  • You stay irritable, short fused.
  • You keep waiting for a good week. It keeps not coming.
  • The things that used to excite you just feel heavy now.
  • You lie in bed exhausted but your mind will not stop.
  • You stop saying you are tired. You just become someone who is always tired.
  • You start to think this is just what your getting older feel like.

If you start tomorrow

  • You reach for the third coffee less. You just do not need it anymore.
  • You finish a task without losing the thread halfway through.
  • You sit down to work and actually work.
  • The people around you notice. You are there again.
  • You laughed at dinner. Really laughed.
  • Week two, you feel steadier. The building has started.
  • The short fuse gets longer. You’re more patient and less irritable.
  • The afternoon meeting does not scare you anymore. You show up clear.
  • You stop losing your thoughts in the middle of a sentence.
  • That feeling of being on top of things. It starts coming back.
  • You stop feeling like you are “performing” the sharp version of you. You just are.
  • You did not have to medicate. You did not have to push harder. You just took the first step.
  • You finally feel genuinely present and focused.

Both roads start tomorrow morning. You get to pick which one.

sayaka doesn’t claim to fix every single one of these problems. These lifestyle changes require commitment and self improvement alongside.

Become the focused version of yourself

Each one with its place in your routine. Purposely formulated.

It’s not your fault, and there’s a fix

Have you met the thieves of your focus?

Happens every day, and if you don’t act, it will happen tomorrow. These are the main reasons adults in North America lack focus.* They all get worse with time.

*Results vary by person. How well these ingredients work depends on your health, diet, sleep, and lifestyle. Some ingredients in our formulas have been studied at doses that differ from those used here. We chose our doses on purpose. We are not chasing quick results. Natural ingredients build on each other, a little more every day. Rome was not built in a day. A clearer mind is not either.

A note from our founder, Aiko

Aiko, founder of sayaka

During the Covid pandemic, I fell into a depression. I was home all day and could not focus on anything, not work, or my daughters, or my husband. I didn’t even have energy to go to the gym.

I started taking more than ten supplements a day hoping something would help (and lots of coffee, I love coffee). It helped, but my sleep was still terrible. Melatonin made me feel groggy in the morning, and no matter what I tried, I kept forgetting to drink water. Simple things stopped happening.

So I made a rule. Five minutes, every morning. I take my supplements, drink a tall glass of water. And at night, a sleep formula with no melatonin.

It worked. Not perfectly. Not like the person I was before. But enough to think clearly again.

With some of my focus back, I spent the rest of that year researching. Reading every study I could find. I wanted to know what was actually working and why. I wanted to build one honest, simple system. Not a magical pill, those don’t exist, or are caffeine-packed.

That is sayaka. I named it after my grandmother. She was calm and sharp her whole life. That is what I was reaching for.

By far, the biggest finding was the ingredients that I put in the sleeping capsule. I now sleep like a baby, something that had never happened before to me.

I take it every single morning. Because I need it too.

– Aiko N.

Aiko’s sister before and after. 3 months apart.

These results are anecdotal and she made other lifestyle changes alongside sayaka, but she attributes a great part of her sleep quality improvement to the sayaka night pill.
