How to use it
+
Dosage: Take 1-2 capsules daily with water, preferably with a meal.
Timing: Morning or evening—consistency matters more than specific timing. Choose a time you'll remember and stick with it.
With or without food: We recommend taking with food to support optimal strain colonization and reduce any initial digestive adjustment.
Storage: Keep in a cool, dry place. Refrigeration is not required but can extend shelf life in hot climates.
Important notes:
- Take consistently—microbiome optimization requires daily use
- Don't skip doses during the first 3 months (critical colonization period)
- If you miss a day, resume normally the next day (don't double dose)
- Can be taken alongside other supplements
First 2 weeks: Some users experience mild digestive adjustments (normal—your microbiome is recalibrating). Stay consistent through this adaptation phase.
Whats in it?
+
Your formula is custom-engineered, so ingredients vary based on your unique DNA and microbiome analysis. However, all formulas share these standards:
Core Components:
- Precision-selected probiotic strains (species and CFU counts determined by your test results)
- Prebiotic fibers to support strain colonization
- Vegetarian capsule (plant-based, no gelatin)
What's NOT in your formula:
- No artificial fillers or binders
- No GMOs
- No gluten, dairy, or soy
- No unnecessary additives
Strain categories we engineer from:
- Lactobacillus species (energy, digestion, immune function)
- Bifidobacterium species (inflammation control, gut barrier health)
- Streptococcus thermophilus (lactose metabolism, immune support)
- Bacillus species (resilience, spore-forming stability)
Potency: Each serving delivers 10-50 billion CFUs depending on your custom formulation needs.
Quality assurance:
- Manufactured in FDA-registered, GMP-certified facilities
- Third-party tested for purity and potency
- Strain-specific DNA verification
Full ingredient breakdown: Your personalized ingredient list and strain details are included with your formula delivery and accessible in your secure account dashboard.
Does it really work?
+
Yes—and here's the evidence:
Clinical Research:
Over 200 peer-reviewed studies demonstrate probiotic supplementation in athletes delivers measurable performance improvements:
- Up to 40% reduction in sick days (more consistent training)*
- 25-45% fewer exercise-induced GI symptoms (cramps, bloating, urgency)*
- 10-25% reduction in oxidative stress markers (faster recovery)*
- Enhanced nutrient absorption efficiency (better fuel utilization)*
The Craft Difference:
Generic probiotics show these population-level effects. The Craft Protocol personalizes strain selection based on YOUR biology—meaning you're not getting average results, you're getting optimized results.

"Recovery time dropped by a third. My energy is consistent all day—no more 3pm crashes. I've PR'd in every distance since starting The Craft Protocol."
"I hit a 50lb PR on my deadlift within 8 weeks. Digestion is locked in. Recovery is faster than it's ever been. The Craft Protocol fixed what I didn't even know was broken."
"I've reviewed hundreds of microbiome products. The Craft Protocol is the only one using elite athlete benchmarking and true DNA personalization. It's not even close."
"Ultra running destroys your gut. The Craft Protocol rebuilt mine from the ground up. I finished my last 100-miler without a single GI issue. That's unheard of for me."

What Our Customers Are saying...
Great Results
I train 6 days a week and used to get sick constantly. Since starting Craft, I haven't missed a single workout in 3 months. Recovery feels faster and my stomach doesn't hate me during long runs anymore.
Huge Difference!
Honestly, I was skeptical about the whole 'custom probiotic' thing. But the testing process was legit and I've noticed real changes—less bloating, better sleep, and my brain fog is basically gone.
Worth Every Penny
I used to crash every afternoon around 3pm, no matter what I ate. Two weeks into The Craft Protocol and my energy is stable all day. I can actually focus through evening workouts now without feeling wrecked.
Finally Relief
I used to get terrible stomach cramps during CrossFit WODs. Tried cutting dairy, gluten, everything. Turns out my gut just needed the right strains. Zero issues now, even on max effort days.

Here's what the research actually says about microbiome-based performance optimization
Week 1-2: Initial Adaptation
Your custom formula begins populating beneficial strains. You may notice initial digestive adjustments as your microbiome recalibrates. This is your biology responding to precision optimization not generic guesswork.
Week 3-4: Clarity & Consistency Emerge
Most users report noticeable improvements in mental clarity, energy stability, and reduced bloating. Your gut-brain axis starts optimizing. Digestive efficiency improves. You're building the foundation for deeper performance gains.
Week 6-8: Recovery & Output Improve
Recovery between training sessions accelerates. Energy production stabilizes throughout the day. Many athletes report reduced GI distress during high-intensity efforts. Your microbiome is now actively supporting performance output.
Week 12+: Deep Resilience & Sustained Gains
Immune resilience strengthens. Hormonal balance stabilizes. Training consistency improves. This is where the compounding effects of optimized biology become undeniable fewer sick days, faster adaptation, sustained performance under load.
Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
How is The Craft Protocol different from store-bought probiotics?
+
Generic probiotics use one-size-fits-all blends that ignore your unique biology. The Craft Protocol is engineered from your DNA and gut microbiome analysis, benchmarked against elite athletes, and customized to target your specific deficiencies—not random strain selection.
What's included in my protocol?
+
✓ DNA + Gut Microbiome Test Kit
✓ Complete strain analysis (10,000+ markers)
✓ Elite athlete benchmark comparison
✓ 3-month supply of your custom probiotic formula
✓ Secure biome profile storage
✓ Access to reformulation as your biology evolves
How does the testing work?
+
Simple at-home collection: a cheek swab (DNA) and gut sample. Mail it back with prepaid shipping. Our lab sequences 10,000+ strains, compares your biology to elite performer benchmarks, and engineers your custom formula. Total timeline: 4-5 weeks from order to delivery.
What's the difference between 1-strain, 2-strain, and 3-strain formulas?
+
Single Strain: Foundational gut optimization—best for baseline health and digestive support
2-Strain: Multi-system targeting—best for recovery, energy, and mental clarity
3-Strain: Comprehensive engineering—best for hormones, strength, complete performance optimization
Your test results will recommend the best tier for your biology.
When will I see results?
+
Most users notice initial improvements—mental clarity, stable energy, better digestion—within 2-4 weeks. Deeper performance gains like faster recovery and immune resilience typically emerge within 6-12 weeks as your microbiome stabilizes.
Why is there a 3-month minimum?
+
Real microbiome shifts require time. Clinical research shows meaningful changes in strain diversity and functional markers occur within 6-12 weeks of consistent use. The 3-month minimum ensures you experience true biological adaptation—not placebo effects.
