Description
+
Craft Complete is an elite-performance probiotic engineered from strains sourced from world-class athletes. Unlike generic probiotics that use random bacterial strains, Complete is formulated with clinically-backed organisms proven to optimize gut health, mental clarity, and immune resilience.
Each formula contains precision-dosed strains of Lactobacillus rhamnosus (anti-fatigue, cognitive function), Bifidobacterium longum (gut integrity), and Lactobacillus reuteri (gut-brain axis optimization). The result: faster nutrient absorption, reduced bloating, sharper focus, and stronger immunity.
Craft Complete is designed for athletes, biohackers, and high-performers who demand more than "general gut health." This is optimization for people who track their biology.
Who should use Craft Complete?
+
- CrossFitters and functional fitness athletes balancing strength + endurance
- Biohackers optimizing digestion, energy, and cognitive performance
- Anyone experiencing bloating, irregular digestion, or post-meal fatigue
- Athletes seeking foundational microbiome support without DNA testing
How do I take it?
+
Take one serving daily with water, preferably with your first meal to maximize absorption and support digestion throughout the day. Consistency matters more than timing—your microbiome thrives on routine.
For athletes training at high intensity, some users take their dose post-workout to support recovery and reduce inflammation. There's no "wrong" time, but morning dosing ensures you don't forget.
What strains are in it?
+
Craft Complete contains elite-verified strains sourced from athlete microbiomes:
- Lactobacillus rhamnosus — Reduces fatigue, supports mental clarity, strengthens gut barrier integrity
- Bifidobacterium longum — Optimizes digestion, reduces bloating, enhances immune function
- Lactobacillus reuteri — Improves gut-brain axis communication, supports hormonal balance
Each strain is third-party verified via Illumina sequencing to ensure purity, potency, and strain-specific identity. We don't use filler strains or generic "blends"—every organism has a performance purpose.
What results can I expect?
+
Most users notice initial improvements within 2-4 weeks:
- Reduced bloating and post-meal discomfort
- More stable energy throughout the day (no afternoon crashes)
- Improved mental clarity and reaction time
- Faster recovery between training sessions
Deeper microbiome shifts—like enhanced immunity and metabolic optimization—develop over 6-12 weeks of consistent use. Your microbiome is a living system; long-term consistency drives long-term results.

"I've been chasing faster recovery times for years. Two weeks into Craft Complete, my post-WOD bloating disappeared and my energy stayed stable all day. No more 3pm crashes. This is the only probiotic I've used that actually feels different."
"Between training, classes, and travel, my digestion was a mess. Craft Complete stabilized everything—no more bloating, no more inconsistency. I feel lighter, faster, more focused. It's like upgrading your engine's fuel system."
"Most probiotics are under-dosed or use cheap strains. Craft's athlete-sourced approach is what caught my attention—and the results kept me using it. My patients ask what I take for gut health. This is the only probiotic I recommend without hesitation."
"I track everything—HRV, sleep, bloodwork, training load. Craft Complete was the variable that moved the needle on my recovery metrics. Better gut health cascaded into better sleep, lower inflammation, and clearer focus. Data doesn't lie."

What Our Customers Are saying...
Great Results
I'm a competitive runner and gut health has always been my weak point. Since starting Craft Complete, no more race-day stomach issues. I can finally fuel properly without worrying. Game-changer.
Huge Difference!
Finally, a probiotic that actually does something. My digestion feels smoother, no more post-meal heaviness, and my recovery between workouts improved. I've tried other brands—this one's different.
Worth Every Penny
I was skeptical about probiotics, but my gut issues were getting worse with training. Three weeks in and my bloating is gone, energy is way more consistent, and I'm not dragging after lunch anymore. Wish I'd started this sooner.
Finally Relief
My brain fog cleared up within two weeks. I didn't realize how much my gut was affecting my focus until it wasn't a problem anymore. Energy is stable all day now. Worth every penny.
Frequently Asked Questions
Find answers to common questions about our products, shipping, returns, and more.
Are your products tested for quality?
+
Yes. Every batch of Craft Microbiome products undergoes rigorous third-party testing to ensure purity, potency, and strain accuracy. We use Illumina genetic sequencing to verify the identity of every probiotic strain, confirming that what's on the label matches what's in the bottle.
Our formulas are manufactured in FDA-registered, GMP-certified facilities following the highest quality standards. Each strain is tested for:
- Genetic identity verification
- Colony-forming unit (CFU) count accuracy
- Contamination and purity
- Shelf-stability and potency retention
We don't cut corners. Your biology deserves precision.
Can I take Craft products with other supplements?
+
Yes. Craft Microbiome formulas are designed to stack with other supplements like protein powder, creatine, vitamins, and minerals. Probiotics actually enhance nutrient absorption, making your other supplements more effective.
One exception: Avoid taking probiotics within 2 hours of antibiotics, as antibiotics can kill probiotic bacteria. Space them out for maximum benefit.
How should I store my probiotics?
+
Store Craft Microbiome products in a cool, dry place away from direct sunlight and heat. Refrigeration is not required—our strains are shelf-stable and maintain potency at room temperature.
Keep the bottle tightly sealed to protect from moisture. Do not store in the bathroom (humidity can affect probiotic viability).

What makes Craft Microbiome different from other probiotics?
+
Three critical differences:
- Athlete-Sourced Strains: We isolate probiotic strains from elite athlete microbiomes, not generic lab cultures. These bacteria are performance-selected, not randomly chosen.
- Clinical Validation: Every strain is backed by published research showing measurable benefits (increased muscle mass, reduced fatigue, improved gut health, testosterone support).
- Precision Formulation: We don't pad formulas with filler strains to inflate CFU counts. Every organism in the bottle has a specific performance purpose.
Most probiotics optimize for shelf presence and marketing. Craft optimizes for results.
