Most Athletes Never Unlock Their Full Biology

Craft decodes your unique biological blueprint and builds daily probiotics tailored to what your body actually needs — giving you targeted support for better energy, recovery, focus, and resilience.

One Daily Formula  Multiple Performance Benefits

One Daily Formula  Multiple Performance Benefits

Faster Recovery

Your microbiome is key to controlling inflammation and repairing muscle. Our formula strengthens the strains that speed up recovery — helping you reduce soreness, rebuild faster, and stay consistent.

Peak Energy Production

Energy starts in the gut. We enhance the bacteria that turn nutrients into clean, steady fuel — no spikes, no crashes. Just the metabolic efficiency athletes need for sustained power and endurance.

Sharper Mental Performance

Your gut and brain stay in constant sync. Our blend strengthens that link to improve focus, decision-making, and clarity under pressure.

Hormonal Balance

Stress, sleep, and performance depend on balanced hormones. Our formula supports a healthier microbiome to steady cortisol, optimize testosterone, and boost resilience.

Frequently Asked Questions

Find answers to common questions about our products, shipping, returns, and more.

What makes Craft different from other probiotics? +

Three critical differences:

  1. Athlete-Sourced Strains: We isolate probiotic strains from elite athlete microbiomes, not generic lab cultures. These bacteria are performance-selected, not randomly chosen.
  2. Clinical Validation: Every strain is backed by published research showing measurable benefits (increased muscle mass, reduced fatigue, improved gut health, testosterone support).
  3. 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

How long does shipping take? +

Domestic (US) Shipping:

  • Orders ship within 1-2 business days
  • Delivery takes 3-5 business days (standard shipping)
  • Expedited options available at checkout (2-3 day or overnight)

International Shipping:

  • Available to select countries
  • Delivery times vary by region (7-14 business days typical)
  • Customs fees and import duties may apply (customer responsibility)

You'll receive tracking information via email as soon as your order ships.

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.

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).

Are Craft products safe? +

Yes. Craft Microbiome products are formulated with clinically-studied probiotic strains that have a long history of safe use. Our formulas are:

  • Vegan and allergen-free (gluten, dairy, eggs, corn, soy)
  • Non-GMO
  • Free from artificial additives, fillers, or unnecessary ingredients
  • Third-party tested for purity

If you're pregnant, nursing, or managing a medical condition, consult your physician before starting any new supplement regimen. While probiotics are generally safe, individual biology varies.
