UpperDose helps you lower toxins hiding in your routine.

You filter your water, read ingredient labels, maybe even switched to glass containers. But the exposures adding up fastest are the ones hiding inside products you never thought to question. Your toothbrush. Your tap. Your morning cup of coffee. The research is specific, and it is not subtle.

Your toothbrush sheds plastic twice a day. Here's what replaces it.

  • Bristles that do not shed microplastics

    Standard electric toothbrush heads use nylon filaments that break down with every use. Boar bristle is a natural filament that cleans without releasing synthetic particles into your mouth twice a day.

  • Sonicare compatible cleaning without the plastic trade-off

    Manual bamboo brushes solve the bristle problem but give up cleaning performance. This brush runs on sonicare vibration with natural boar bristle heads, so you are not trading one problem for another.

  • Replace the head. Keep the handle

    The bristle head swaps out every three months. Your sonicare handle stays. No throwing away a functioning motor, no buying a full new device, no extra plastic in the bin.

The things you trust most are the ones you haven't checked.

5 grams of plastic per week.

That is the weight of a credit card. You are likely ingesting that much microplastic every seven days through water, food packaging, and household products.

Microplastics detected in 80% of human blood samples tested.

A 2022 study in Environment International found plastic particles circulating in the bloodstream of nearly every participant. This is not a future risk. It is a current one.

94% of U.S. tap water contains microplastics.

Independent testing by Orb Media found synthetic fibers in tap water samples across the country. The filter on your Brita was not designed for particles this small.
