Time to decide whether PCC1 is right for you.
Ageing cells can fuel inflammation.
Identify
Some ageing cells stop dividing but remain in the body. These “zombie” cells release inflammatory signals that affect the healthy cells around them.
Clear
Procyanidin C1, a key compound in PCC1™, has been shown in lab studies to trigger the self-destruct process in senescent cells.
Renew
With fewer zombie cells, healthy cells can function in a less inflammatory environment.

Explore the science
Nature makes it. We concentrate it.
Polyphenols are natural compounds found in foods such as olive oil, green tea and cocoa. Procyanidin C1 belongs to this family and occurs in grape seeds.
We purify selected grape-seed compounds, then combine procyanidin C1, procyanidin B2 and epicatechin in a deliberately chosen ratio. This is PCC1™: our concentrated polyphenol blend.
Made to be absorbed.
We pair our grape-seed polyphenols with sunflower phospholipids. This delivery complex, called a phytosome, helps carry compounds that are otherwise poorly absorbed.

Good to know.
When will I notice a difference?
PCC1™ is designed as ongoing monthly cellular maintenance rather than a quick fix, so we suggest running the protocol consistently. Everyone is different, and it’s a dietary supplement, not a medicine intended to diagnose, treat or cure disease.
Why is it a 3-day monthly format?
Senolytics are typically studied as short, spaced pulses rather than daily doses. PCC1™ follows that idea: three days on, then twenty-seven days of rest — one complete 30-day cycle per box.
Can I take it with supplements or medication?
Ask your healthcare professional before starting PCC1™ if you take medication or other supplements, have a medical condition, are pregnant or nursing, or are under 18. They can advise on your individual circumstances.
What if it’s not right for me?
PCC1™ is covered by a 90-day money-back guarantee. Contact us within the period and we’ll take care of it under that policy.
