Launching soon — made in Canada

You eat
plastic
every day.
We made
something for that.

The average person swallows a credit card's worth of tiny plastic particles every week. They end up in your blood, your gut, your organs. You can't stop it. But you can give your body what it needs to handle it.

The problem

It's not a future risk.
It's happening now.

Tiny plastic particles — smaller than a grain of sand — are now in your food, your water, and the air you breathe. Bottled water. Seafood. Sea salt. Fruit. Tea bags. Even tap water. You can't avoid them, no matter how carefully you eat.

Once they're inside you, the smallest particles slip through your gut wall and into your bloodstream, where they accumulate over years. Your body has never encountered this before — and it shows.

The formula

Six ingredients.
Built for one job.
One capsule daily.

Hover each ingredient to see the research behind it. We show our work.

Counters cell damage
Curcumin
500mg (95% extract + piperine)
Turns on your body's own built-in protection system against the cellular damage plastic causes. Think of it as activating your body's repair mode.
PMC12291741: Mitigates MP-induced oxidative damage in cell studies. Mashayekhi-Sardoo et al., 2024: curcumin restored all oxidative damage induced by microplastics. Activates Nrf2-Keap1 signalling pathway.
Counters cell damage
Quercetin
250mg
A natural compound from plants that damps down the inflammatory response plastic triggers. Works alongside curcumin — together they're significantly more effective than either alone.
PMC12291741: Reduces cell damage markers and inflammatory signals in microplastic exposure models. Synergistic quercetin + selenium schemes show environmental relevance.
Counters cell damage
Vitamin C
500mg
Mops up the harmful molecules plastic generates inside your cells, and helps your body produce glutathione — the most important antioxidant your body makes itself.
2025 biological monitoring: higher plasma Vitamin C associated with reduced cellular damage markers from environmental toxin exposure. Supports glutathione synthesis.
Protects your gut
Zinc Carnosine
75mg (PepZin GI®)
Coats and protects the lining of your gut, which plastic physically damages. In a clinical trial, it prevented a threefold increase in gut leakiness compared to placebo.
Mahmood et al., Gut journal (2007) RCT: prevented 3× increase in gut permeability vs placebo. Japan-approved for gastric ulcers. Reduces local inflammatory signals (TNF-α, IL-6).
Protects your gut
L-Glutamine
2,000mg
Your gut lining is only one cell thick. L-Glutamine is the primary fuel those cells run on. More of it means a stronger, faster-repairing gut wall — exactly what plastic exposure compromises.
Nutrients (2017): improved gut lining integrity and reduced permeability in clinical subjects. Li et al. (2004): glutamine regulates the proteins that hold gut cells tightly together.
Restores gut bacteria
Lactobacillus acidophilus
10 Billion CFU
Plastic disrupts your gut bacteria — the community of microorganisms that run your immune system and digestive health. This strain helps restore the balance plastic throws off.
PMC11635378: Plastic exposure linked to reduced microbial diversity, increased harmful bacteria, and chronic inflammatory conditions including IBD and metabolic disease.
How it works

Three ways plastic
hurts you. All addressed.

01
Cell damage
It damages
your cells

Plastic particles inside your body generate harmful molecules that damage your cells from the inside — a bit like rust forming on metal. Curcumin, quercetin and vitamin C neutralise these before they cause lasting harm.

02
Gut damage
It damages
your gut lining

Your gut wall is your body's main barrier against toxins. Plastic weakens it, making it easier for harmful substances to enter your bloodstream. Zinc carnosine repairs the damage. L-glutamine fuels the cells doing the rebuilding.

03
Inflammation
It inflames
your whole body

Your immune system recognises plastic as a foreign invader and responds with inflammation — useful in a crisis, harmful when it never stops. Quercetin and curcumin interrupt that signal, helping your body stand down.

The science

We show our work.

Every ingredient in Byeplast is chosen because of published human or cell research showing it works against the specific damage plastic causes. We don't call it a "detox." We don't use ingredients because they sound good. We pick doses that match what researchers actually tested — and we show you exactly where the evidence comes from.

"Microplastics can increase intestinal permeability, trigger inflammatory responses, and induce oxidative stress — all of which contribute to metabolic changes and impact liver function and overall metabolism."
