Is it better to take pre and probiotics together?

4 min read

According to the International Scientific Association for Probiotics and Prebiotics (ISAPP), a synbiotic is a mixture of live microorganisms and substrates that confers a health benefit on the host. This potent combination, answering the question 'Is it better to take pre and probiotics together?', involves a partnership where prebiotics act as food for the probiotics, helping them flourish and multiply.

Quick Summary

Taking prebiotics and probiotics together can provide synergistic benefits, with prebiotics acting as a fuel source to enhance the effectiveness and survival of probiotic bacteria. Combining them can improve digestive health, boost immune function, and better balance the gut microbiome.

Key Points

  • Synergistic Effect: Combining prebiotics and probiotics (known as a synbiotic) is generally more effective for gut health than taking either alone, as prebiotics provide the necessary fuel for probiotics to thrive.

  • Enhanced Viability: Prebiotic fibers increase the survival rate of probiotic bacteria as they travel through the digestive system, ensuring more beneficial microbes reach the gut.

  • Supports Native Bacteria: Prebiotics also nourish the healthy bacteria already living in your gut, including anaerobic strains that cannot be included in supplements.

  • Boosted Immunity: Approximately 70% of the immune system is in the gut; a balanced microbiome supported by synbiotics can help reinforce the gut barrier and modulate immune responses.

  • Improved Digestion: Taking prebiotics and probiotics together can lead to better overall digestive function and relief from common issues like bloating and gas.

  • Consider Food and Supplements: While synbiotic supplements offer convenience, a diet rich in natural sources like bananas and yogurt provides a great foundational approach.

  • Manage Initial Discomfort: Mild, temporary side effects like bloating can occur as the gut adjusts, but starting with a lower dose and staying hydrated can help.

  • Consult a Professional: Individuals with weakened immune systems or underlying conditions like SIBO should consult a healthcare provider before starting a synbiotic regimen.

The Synergistic Power of Synbiotics

The human gut is a complex ecosystem, home to trillions of microorganisms collectively known as the gut microbiome. The balance of this microbial community is crucial for overall health, influencing everything from digestion and nutrient absorption to immune function and even mental well-being. Probiotics and prebiotics are two key players in maintaining this balance. While often discussed separately, the question of whether it is better to take pre and probiotics together leads us to the concept of 'synbiotics'—a powerful combination designed for enhanced effect.

Understanding Prebiotics vs. Probiotics

To grasp the full benefit of combining these supplements, it's essential to understand their individual roles. Probiotics are live, beneficial microorganisms that, when ingested, add to the population of good bacteria in your gut. They can be found in fermented foods like yogurt, kefir, and sauerkraut, or taken as a supplement. In contrast, prebiotics are non-digestible fibers that serve as a food source for these probiotics and the good bacteria already residing in your gut. They are found in high-fiber foods such as onions, garlic, bananas, and oats. A simple analogy, often used by experts, compares the gut to a garden: probiotics are the seeds you plant, and prebiotics are the fertilizer that helps them grow and thrive.

Benefits of the Combined Approach (Synbiotics)

Taking prebiotics and probiotics together can create a more potent and effective approach to gut health. Research has shown that this synergistic relationship offers several key advantages:

  • Enhanced Survival and Effectiveness of Probiotics: Prebiotics provide a food source that nourishes the probiotic bacteria, helping them to survive the harsh acidic environment of the stomach and successfully colonize the large intestine. This significantly improves their viability and impact.
  • Improved Digestive Wellness: This combination can help address common digestive issues like bloating, gas, and constipation. By promoting a balanced microbiome, synbiotics contribute to more regular and comfortable bowel movements.
  • Stronger Immune System Support: A large portion of the body's immune system is in the gut. By promoting a healthy microbiome, synbiotics can reinforce the gut barrier and help modulate immune responses, potentially reducing inflammation.
  • Support for the 'Native' Gut Microbiome: In addition to feeding the new, supplemented bacteria, prebiotics also nourish the beneficial anaerobic bacteria already present in your gut that cannot be provided through supplements.

Synbiotic vs. Individual Supplements: A Comparison

Feature Probiotics Alone Prebiotics Alone Synbiotics (Combined)
Mechanism Introduces new beneficial live bacteria to the gut. Provides a food source to nourish existing bacteria. Combines both live bacteria and their food source in one product.
Target Audience Individuals seeking to restore gut flora after antibiotics or illness, or to address specific digestive issues. Individuals aiming to support and nourish their existing gut bacteria, particularly through diet. Individuals seeking maximum effectiveness, convenience, and a more comprehensive gut health approach.
Efficacy Can be effective, but viability may be compromised by stomach acid without a protective mechanism. Supports existing flora, but does not introduce new strains that may be lacking. Generally considered more effective, as the prebiotic enhances the survival and growth of the probiotic.
Primary Source Fermented foods (yogurt, kefir, etc.) or supplements. High-fiber foods (onions, garlic, oats) or supplements. Fortified foods or dedicated supplements containing both components.
Convenience Moderate (requires managing separate food or supplement intake). Moderate (requires managing separate food or supplement intake). High (single product for both components).

How to Take Synbiotics for Optimal Results

For those wondering about the best way to incorporate this powerful duo, here are some practical tips:

  • Choose a High-Quality Synbiotic Supplement: Look for products that list the specific strains of bacteria (e.g., Lactobacillus or Bifidobacterium) and the CFU count. High-quality synbiotics will often list specific prebiotics like inulin or FOS.
  • Consider Timing: Some experts suggest taking synbiotics on an empty stomach to maximize the bacteria's survival through the digestive tract. For products delivered as powders activated in water, consuming them in the morning before breakfast is often recommended.
  • Start Gradually: To minimize potential initial side effects like bloating or gas, begin with a lower dose and increase it gradually over time.
  • Combine with a Diverse Diet: While supplements are convenient, they should complement, not replace, a diet rich in both prebiotic and probiotic whole foods. Enjoying yogurt with berries or a barley soup with onions and garlic provides a natural synbiotic effect.
  • Consult a Professional: It is especially important for individuals with compromised immune systems or pre-existing digestive conditions like Small Intestinal Bacterial Overgrowth (SIBO) to consult a healthcare provider before starting a synbiotic regimen.

Conclusion: The Final Verdict

It is indeed better to take pre and probiotics together, as the synergistic effect of a synbiotic approach offers a more comprehensive and effective strategy for promoting gut health. By providing beneficial bacteria and the food they need to thrive, synbiotics support a healthier, more balanced gut microbiome. While this can be achieved by combining prebiotic-rich foods with probiotic foods, modern synbiotic supplements offer a convenient and highly targeted method to achieve this powerful one-two punch. Whether through diet or supplementation, intentionally pairing prebiotics and probiotics is a smart and science-backed way to support your digestive and overall wellness.

Frequently Asked Questions

Probiotics are live, beneficial bacteria, while prebiotics are non-digestible fibers that act as food for those bacteria. A synbiotic is a supplement or food that combines both prebiotics and probiotics for a synergistic effect.

Probiotic foods include yogurt, kefir, sauerkraut, and kombucha. Prebiotic foods are typically high in fiber, such as garlic, onions, bananas, oats, and asparagus.

Taking synbiotics on an empty stomach is often recommended to maximize the survival of the live probiotic bacteria as they pass through the stomach's acid. Consistency is more important than exact timing.

While generally safe, high doses of prebiotics can cause temporary digestive discomfort like gas and bloating. It is important to follow dosage recommendations and gradually increase intake to allow your body to adjust.

Some people may experience mild gas, bloating, or changes in bowel movements when first starting. These side effects typically subside as your gut adjusts, but consult a doctor if they persist.

Individuals with weakened immune systems (e.g., HIV, post-transplant) or severe illnesses should consult a healthcare professional before taking supplements with live bacteria. People with SIBO should also be cautious with prebiotic intake.

A varied diet rich in plant-based foods and fermented products can provide good amounts of prebiotics and probiotics. However, supplements can offer higher, more concentrated doses for targeting specific health issues, especially if you have a sensitive digestive system.
