The sizing is not an accident

A bottle that does the measuring for you.

01

Fill it.

500 ml is just under 17 oz. One stick of Current wants 12 to 16. No measuring cup, no guessing.

02

Tear a stick.

One stick, one bottle. The dose is calibrated to the container, so every mix tastes the same.

03

Shake. Done.

Sealed lid means you can actually shake it. Minerals in solution in about five seconds.

Why we made it

We obsess over what goes in your water. It felt wrong to stop caring at the bottle.

Current is three forms of magnesium, methylated Bs and trace minerals, sourced and dosed with zero shortcuts. Then people were mixing it in whatever plastic bottle was lying around. So we held the hardware to the same standard as the formula: one material that adds nothing and takes nothing away, built to be the last bottle you buy for a while.

Why steel

Yesterday's flavor stays in yesterday.

Plastic bottles shed microplastics into your water, and it gets worse with heat, sunlight and scratches. Steel is non-reactive: no BPA, no plasticizers, nothing leaching into a hot coffee or an acidic mix. And because the surface doesn't scratch into grooves the way plastic does, there's nowhere for odor and bacteria to settle between washes.

Double wall, two jobs

A vacuum between two walls. Temperature stays put.

Heat needs a path to escape or get in. The sealed gap between the inner and outer wall removes that path, so the outside of the bottle stays neutral and the inside holds its temperature for hours.

Cold

Morning ice, afternoon ice.

Fill it with ice water at 8 AM and it's still cold in the afternoon, ready for whenever you tear a stick. No sweating, no ring on your desk.

Hot

Coffee and tea approved.

The same vacuum works in reverse. Pour it hot and it stays drinking temperature through a slow morning, and the steel never takes on the flavor.

Better together

The bottle holds the water. Current makes it count.

Add a pouch of Current, 15 sticks in Lemon Lime, Watermelon or Wild Berry, and every fill becomes 220 mg of magnesium, methylated Bs and trace minerals. Life's better mineralized.
