The hard part

A good habit should not taste like one.

The hard part of any daily supplement is the daily part: a flavored drink you get tired of, a scoop that clumps, one more thing to remember before you leave the house.

So we picked the plainest version there is. One ingredient, no flavor, a powder fine enough to vanish in the coffee you make every morning anyway. Nothing new to remember, nothing to taste.

How it works

Pour. Scoop. Stir.

  1. Pour your coffee

    Hot or iced, black or with milk. Tea, a smoothie or oatmeal work too.

  2. Add one scoop

    One level scoop. The scoop comes in the tub.

  3. Stir and drink

    It dissolves in about ten seconds. No taste, no clumps, no film on top.

Ten seconds, every morning.

What is in the tub

One ingredient. That is the whole label.

Collagen peptides

Hydrolyzed bovine collagen from grass-fed cattle, made in the USA. Nothing else: no flavor, no sweetener, no fillers.

Type I and III

Bovine hide supplies both types, the two most common in the body.

Fine enough to vanish

Hydrolyzed means the collagen is broken into short peptides, so it dissolves instead of setting like gelatin.

A tub for the counter

9.88 oz of powder in a sealed tub with its own scoop. It lives next to the coffee maker.

One scoop. Every day.

Who it is for

For people who want one simple daily habit.

  • The morning coffee

    If you drink coffee every day, the habit is already there. Stirday rides along with it.

  • People who quit flavored powders

    No vanilla, no chocolate, no aftertaste. Your coffee tastes like your coffee.

  • Smoothies and shakes

    After the gym or on a busy morning. It mixes into anything you already blend or shake.

  • Two tubs

    $82 for two tubs in one parcel, so the second one is there when the first runs out.

Questions

Straight answers.

What does it taste like?

Close to nothing. Unflavored collagen peptides have a very mild taste that disappears in coffee, tea or a smoothie. In plain water some people notice a faint note.

Does it dissolve in cold drinks?

Yes, a little slower than in hot ones. Stir it into a splash of the drink first, then add ice and the rest.

How much should I take?

One level scoop a day, as on the label. If you are pregnant, nursing, take medication or have a medical condition, ask your doctor before you start any supplement.

What is it made from?

Bovine hide collagen peptides from grass-fed cattle, made in the USA. One ingredient, nothing added. It is not vegetarian.

Is it a medicine?

No. It is a food supplement, a protein powder for your daily routine. It is not intended to diagnose, treat, cure or prevent any disease.

When will it arrive?

It ships within 2 business days and arrives within 4‑9 business days of your order, with tracking the whole way.

What if it is not for me?

Email [email protected] within 60 days of delivery. We refund the full price and you keep the tub.
