What is a supplement system?

A supplement system is a curated stack of products designed to support one specific biological function — like sleep, gut health, or hormone balance. Instead of buying individual supplements, a system gives you everything you need to support that goal, with ingredients chosen to work together safely and effectively.

Which Body Compass system should I start with?

Start with the system that addresses your most pressing day-to-day concern. If you're struggling with sleep, start with Sleep & Recovery. If digestive issues are affecting your energy, start with Gut Health. You can always expand to additional systems over time.

Can I take more than one system?

Yes. Each system is designed to work independently, but they can also complement each other. Many customers start with one system and add a second once they've established a consistent routine. Our systems are formulated to avoid ingredient overlap.

Do I need a subscription?

No subscription is required. You can purchase any system as a one-time order. However, subscriptions offer convenience and savings — you can pause, skip, or cancel anytime with no fees or commitments.

How long until I notice results?

Results vary by individual and system. Some people notice changes within the first 1–2 weeks, while others may take 4–8 weeks of consistent use. Supplements work best as part of a daily routine, so consistency is key for optimal results.

What is Core Biome 40 and how is it different from other probiotics?

Core Biome 40 is a high-potency probiotic supplement featuring 40 billion Colony Forming Units (CFUs) and a diverse blend of specific Lactobacillus and Bifidobacterium strains, along with prebiotics. Its distinction lies in its multi-strain, synbiotic formulation designed for thorough gut, immune, and particularly women's vaginal health, moving beyond generic, single-strain offerings.

Are probiotics for women different from probiotics for men or kids?

While many probiotic benefits are universal (gut, immune), certain strains are particularly beneficial for women's unique health needs, such as supporting vaginal microbiome balance (e.g., specific Lactobacillus strains). Core Biome 40 is formulated with these considerations. For men, general gut and immune support is key. For children, specialized pediatric probiotics with appropriate dosing are typically recommended, and consultation with a pediatrician is advised.

How long does it take to see results from Core Biome 40?

Results can vary. Some individuals may notice subtle digestive improvements within days or weeks. However, significant and lasting benefits, such as enhanced immune function or more stable vaginal health, typically require consistent use over several weeks to months as the gut microbiome gradually rebalances. Patience and consistency are key.

Can I take Core Biome 40 if I'm taking antibiotics?

Yes, taking Core Biome 40 during and after antibiotic use can be beneficial. Antibiotics can deplete beneficial gut bacteria. Taking probiotics a few hours apart from your antibiotic dose can help replenish these good bacteria and mitigate antibiotic-associated digestive upset. Always consult your healthcare provider for personalized advice.

What are prebiotics, and why are they included in Core Biome 40?

Prebiotics are non-digestible fibers that act as food for beneficial probiotic bacteria. Their inclusion in Core Biome 40 creates a synbiotic effect, meaning they nourish the probiotic strains, helping them survive, grow, and colonize the gut more effectively, thereby enhancing the overall efficacy of the supplement.

Are there any side effects of taking Core Biome 40?

Most individuals tolerate probiotics well. In the initial days, some may experience mild digestive symptoms like gas, bloating, or changes in bowel movements as the gut microbiome adjusts. These are usually temporary. If symptoms persist or worsen, discontinue use and consult a healthcare professional. It's always advisable to consult a doctor before starting any new supplement, especially if you have underlying health conditions or are pregnant/nursing.

Is Core Biome 40 suitable for vegetarians/vegans?

Please refer to the product label on 21supps.com for specific dietary information regarding Core Biome 40, including whether it is suitable for vegetarian or vegan diets, and for any allergen information.

How should I store Core Biome 40?

Probiotics contain live organisms, so proper storage is crucial for maintaining their potency. Always follow the storage instructions on the product label. Many probiotics, including Core Biome 40, may recommend refrigeration or storage in a cool, dry place away from direct sunlight and moisture to ensure the stability of the live cultures.

Prebiotic Advantage: Included prebiotics nourish beneficial bacteria, promoting their growth and sustained activity.
Evidence-Based Choices: Select probiotics based on research supporting specific strains for desired health outcomes, not just CFU count.
Beyond Digestion: Benefits for probiotics for women extend to immune response, nutrient synthesis, and genitourinary tract balance.

What Is Core Biome 40 and How Does It Support Women's Health?

Core Biome 40 offers a strategic approach to microbiome support, formulated with beneficial bacteria and prebiotics to optimize gut health and influence systemic well-being, particularly for women. It employs a diverse consortium of microorganisms, aiming to replicate a healthy human microbiome's natural complexity.

Understanding the Core Biome 40 Formulation

The "40" in Core Biome 40 signifies its potency: 40 billion Colony Forming Units (CFUs) per serving. This concentration ensures sufficient live bacteria reach the gut. However, efficacy also relies on specific strains:

Multi-Strain Diversity: Core Biome 40 typically features a blend of Lactobacillus and Bifidobacterium species.
- Lactobacillus Strains: Support digestive health, nutrient absorption, and immune function. Critically, species like L. rhamnosus and L. reuteri are recognized for maintaining a healthy vaginal microbiome, preventing imbalances.
- Bifidobacterium Strains: Crucial for colon health, aiding in carbohydrate breakdown, producing short-chain fatty acids (SCFAs), and contributing to immune modulation.
Prebiotic Inclusion: Core Biome 40 incorporates prebiotics (e.g., FOS, Inulin). These non-digestible fibers act as "food" for beneficial bacteria, stimulating their growth. This synbiotic combination enhances probiotic survival and colonization.

The Broader Impact of Probiotics for Women

While often linked to digestion, Core Biome 40's benefits extend beyond the gut, especially for women:

Digestive Harmony: Supports healthy digestion, aids nutrient absorption, promotes regularity, and mitigates occasional discomforts like bloating and gas.
Immune System Support: A significant immune system component resides in the gut. Probiotics interact with immune cells, modulating responses and strengthening natural defenses.
Vaginal Health: A critical area where probiotics for women demonstrate unique benefits. The vaginal microbiome, dominated by Lactobacillus, maintains an acidic environment. Specific probiotic strains help restore and maintain this balance, preventing issues like bacterial vaginosis (BV) and yeast infections.
Mood and Cognitive Function: The gut-brain axis connects the gut and central nervous system. A healthy microbiome can influence neurotransmitter production and reduce inflammation, potentially impacting mood and stress response.
Nutrient Synthesis: Beneficial bacteria can synthesize vitamins (e.g., B vitamins, Vitamin K), contributing to overall nutritional status.

Core Biome 40 provides a strong foundation for these interconnected systems, offering thorough support for women optimizing their health.
