PropolX closes the Open Window — the 3–72 hour post-exercise immune gap that leaves athletes exposed. Back it with 27 clinical trials.
A 7-day illness means 2–3 weeks before you're back at baseline. One cold in peak week costs a month of progress.
3 to 72 hours after every hard session, your immune defenses drop. This is when athletes get sick. This is what PropolX addresses.
44% of marathon runners experience upper respiratory symptoms in the 14 days after a race. All that training. One race. Then a cold.
Every team session, club ride, gym floor, and pool lane is a shared infection vector. When training intensity peaks, immunity dips — right when group exposure is highest. The harder you push, the more exposed you are.
October to March: peak training load meets peak viral season. Vitamin D drops. Social exposure rises. Athletes get sick. PropolX was built for this.
Propolis has been studied in 27 randomized controlled trials. The result: measurably fewer infections, faster recovery, and direct suppression of the Open Window effect in athletes. 55% fewer illness episodes (Cohen 2004, JAMA). 83% complete symptom remission in 3 days (Esposito 2021). Upper respiratory illness accounts for 35–65% of all non-injury athlete illness. PropolX exists to eliminate that statistic from your training year.
Every intense session suppresses your immune system for 3–72 hours. This is the Open Window — the documented period when athletes are most vulnerable to infection. The harder and longer you train, the wider it opens.
PropolX's standardized polyphenol extract — rich in quercetin, kaempferol, and CAPE — modulates the NF-κB inflammatory pathway and boosts antioxidant defenses via Nrf2. The result: your immune system stays primed, not suppressed.
Immune defenses remain maintained through your training blocks. Illness frequency drops. Recovery improves. You hit more sessions, reach peak form, and don't lose weeks rebuilding base fitness after a cold. All year.
Most propolis supplements are crude, inconsistent raw extracts — composition varies by season, geography, and method. PropolX is different. The extract behind every capsule is the result of 40 years of specialisation, a patented purification process, and a single controlled source.
PropolX launches this autumn. Right now, we're opening access to a single cohort of founding members — the first 500 athletes who believe training consistency is non-negotiable. This is your invitation.
There is no downside. You're not paying anything today. No credit card. No commitment. When PropolX launches, you're first — at a price that never changes.
"I've been training 12+ hours a week for seven years. This is the first natural immune supplement I've seen with 27 clinical trials behind it. I was on the list before they even asked." — Beta Tester, Amateur Triathlete, Netherlands
