Frequently Asked Questions

When and how should I take Synbiotics 200?

Take 2 delayed-release capsules once daily as a dietary supplement or as recommended by your healthcare professional.

How is Toniiq Synbiotics 200 different from other brands?

Toniiq delivers 200 billion total functional units (TFU) per serving, the highest verified potency in a 2-capsule synbiotic on Amazon. Most competitors max out around 120 billion CFU and don't include postbiotics. We combine 100 billion CFU from 30 diverse probiotic strains with two clinically studied branded ingredients most brands lack: IMMUSE® LC-Plasma (proven to cut sick days by ~30%) and ButyraGen® (delivers the butyrate equivalent of 4g inulin in just 200mg). Plus, our balanced 600mg prebiotic blend is specifically chosen to minimize bloating while feeding your microbiome.

How long until I notice results?

Many users report digestive improvements within 2 to 4 weeks. In clinical studies, ButyraGen® reduced belly pain by 18% and bloating by 15% starting at week 2. IMMUSE®'s immune benefits typically become apparent during cold and flu season with consistent daily use. For optimal gut microbiome rebalancing and long-term benefits, we recommend 60–90 days of continuous use.

Is this safe to take with other supplements or medications?

Synbiotics 200 is generally well-tolerated and safe to combine with most supplements. However, if you're taking antibiotics, immunosuppressants, or have a compromised immune system, consult your healthcare professional before use. Our formula is third-party tested for purity and safety.

Why do I need prebiotics AND probiotics AND postbiotics?

Think of it as a complete ecosystem: Prebiotics are the "food" that feeds beneficial bacteria. Probiotics are the "live reinforcements" that colonize your gut. Postbiotics like IMMUSE® are the "active compounds" that immediately support immune function without needing to grow. This 3-in-1 approach addresses gut health from multiple angles—feeding your existing microbiome, adding beneficial strains, and delivering immune-activating metabolites that work within hours.

Will this cause bloating or gas?

Unlike high-dose inulin products, our formula is designed for comfort. ButyraGen® delivers butyrate without the gas or bloating typical of large prebiotic doses, it provides the equivalent benefit of 4g inulin in just 200mg. Our 4-fiber prebiotic blend (GOS, XOS, FOS, Inulin) is balanced at 600mg to support gut health while minimizing digestive discomfort. In clinical trials, ButyraGen® actually reduced bloating by 15% compared to placebo.

Does this need to be refrigerated?

No. All strains use acid-resistant technology to survive stomach acid, and the formula is shelf-stable at room temperature. This makes it convenient for travel and daily use without worrying about potency loss.

What's the difference between probiotics and postbiotics?

Probiotics are live bacteria that colonize your gut over time. Postbiotics like IMMUSE® LC-Plasma are heat-inactivated (non-living) bacterial cells and their beneficial metabolites that activate your immune system immediately—within hours of consumption. Clinical research shows IMMUSE® directly switches on immune "master cells" (plasmacytoid dendritic cells) without needing to grow or colonize, providing fast-acting immune support alongside the long-term benefits of live probiotics.

Can I take this if I'm sensitive to dairy or gluten?

Yes. Synbiotics 200 is formulated to be allergen-friendly. IMMUSE® is GRAS-certified and allergen-free. However, if you have specific dietary restrictions or severe allergies, please review the full ingredient list or consult your healthcare provider.

Do you test for purity and potency?

Every batch is third-party tested by ISO-certified labs for identity, potency, heavy metals, and microbial contamination. We verify that you're getting the full 200 billion TFU promised on the label. Certificates of Analysis (COAs) are available online for complete transparency.

What if I don't feel a difference?

Gut health improvements can be subtle at first, especially if you're starting from a relatively healthy baseline. Some users notice digestive comfort and regularity within days, while immune benefits become more apparent over weeks and months. Microbiome rebalancing is a gradual process. Consistency is key. If you're not satisfied, check our return policy. We stand behind our product quality.

Is this suitable for vegans/vegetarians?

Yes, our capsules are made from plant cellulose and the formula is vegan-friendly and vegetarian-friendly.
