The Decline Curve: Why Your Microbiome Decides How Fast You Age

Understanding the Protocol

Common questions about our tiers and your longevity journey.

Who is this for?
Element One is designed for adults who want to restore digestive function, metabolic health, and long-term resilience by addressing the root causes of biological decline—starting with the microbiome.

It’s ideal for people who:
  • Experience bloating, irregular digestion, food sensitivities, or gut discomfort
  • Feel low energy, brain fog, mood instability, or poor recovery despite “doing the right things”
  • Have a history of antibiotic use, chronic stress, or restrictive dieting
  • Are noticing age-related changes in digestion, metabolism, or resilience
  • Want a science-driven alternative to generic probiotics and supplements
  • Prefer data-guided, targeted nutrition rather than trial-and-error guessing

Element One is built for those who care not just about feeling better today—but functioning better for decades.
What is the difference between the tiers?
Element One: The foundational daily capsule. It delivers the Keystone Microbes missing from the modern gut.

Element One Complete: The complete system. Includes the capsule plus our Keystone Nutrition drink mix to feed those microbes, ensuring colonization and maximum metabolic output.

Element One Pro: Our clinical-grade tier. It includes microbiome testing, analysis, and a 100% custom-engineered nutritional formula based on your unique biology.
Is Element One Complete worth the upgrade?
Yes. While the daily capsule reintroduces critical species, they struggle to survive without their specific food source. **Element One Complete** provides the exact prebiotic and polyphenol 'soil' these microbes need to thrive, colonize, and produce the anti-aging postbiotics your body craves.
How does the 'Pro' testing work?
We ship you a clinical-grade collection kit. Once you return your sample, our lab maps your gut ecology, biological age, and inflammation markers. We then engineer a custom nutritional powder specifically designed to repair your personal deficits.
How long until I feel a difference?
Days 1-7: You may notice subtle shifts in digestion as your microbiome adjusts.
Weeks 2-4: Users often report improved energy stability (no afternoon crash) and better sleep quality.
Months 3+: This is where the longevity benefits compound—systemic inflammation markers typically decrease, and metabolic resilience improves.
I already take a probiotic. How is this different?
Most probiotics use 'transient' strains (like Lactobacillus) that pass through you without staying. **Element One** uses **resident** human strains (Keystone Species) that are native to a youthful human gut. We aren't just visiting; we are rebuilding the permanent architecture of your microbiome.
Is this safe to take with my other supplements?
Generally, yes. The protocol is nutrition-based. However, if you are on specific medications or have a compromised immune system, we always recommend consulting your physician. If you are taking antibiotics, take your capsule at least 2-3 hours apart from your medication.
