Can I Take Probiotics on a Low-Histamine Diet? A Guide to Safe Strains

Research suggests that some gut bacteria can produce histamine, potentially worsening symptoms for those with histamine intolerance. The key to including probiotics on a low-histamine diet is to select the right strains that won't increase your histamine load.

Quick Summary

Careful probiotic strain selection is needed for a low-histamine diet. Probiotics may help, while others can make symptoms worse. Not all bacteria have the same effect on histamine levels.

Key Points

• Strain Matters: Not all probiotics are the same; some produce histamine while others degrade it, making strain selection critical for a low-histamine diet.

• Avoid High-Histamine Strains: Strains like Lactobacillus casei and Lactobacillus bulgaricus are known histamine-producers and should be avoided.

• Choose Low-Histamine Strains: Opt for histamine-degrading or neutral strains like Bifidobacterium longum, Lactobacillus plantarum, and Lactobacillus rhamnosus.

• Supplements Over Fermented Foods: Probiotic supplements are a safer, more controlled option for HIT as common fermented foods are high in histamine.

• Start Slowly and Monitor: Introduce new probiotics at a low dose and gradually increase while monitoring your body's reactions.

• Address Root Causes: Beyond probiotics, focus on overall gut health by supporting DAO production, reducing inflammation, and managing stress.

The Complex Link Between Your Gut and Histamine

Histamine intolerance (HIT) is a condition where the body struggles to process and break down histamine effectively, leading to a build-up that can cause various symptoms, from headaches and digestive issues to skin rashes. A low-histamine diet is a primary strategy for managing this condition, but many people wonder about adding probiotics for gut health. The gut plays a critical role in regulating histamine levels, primarily through the enzyme diamine oxidase (DAO), which is produced in the gut lining. When gut health is compromised by issues like inflammation, leaky gut, or an imbalanced microbiome (dysbiosis), DAO production can decrease. To complicate matters, some bacteria in the gut naturally produce histamine, while others help degrade it, and an overgrowth of the wrong type can exacerbate symptoms. This means that when it comes to probiotics on a low-histamine diet, not all strains are created equal. In fact, some popular probiotic-rich foods and supplements can be counterproductive for those with histamine sensitivity.

Probiotic Strains: Know Your Friends from Foes

The impact of a probiotic is entirely strain-dependent. While some can help lower histamine levels and restore gut balance, others can actively produce histamine, adding to your body's burden. This is why generalized advice to take probiotics is not sufficient for those with HIT.

Strains to Avoid (Histamine-Producing)

For individuals managing histamine intolerance, avoiding probiotic strains known to increase histamine levels is a crucial step. These are often found in popular fermented foods like some yogurts and fermented vegetables.

• Lactobacillus casei: Various strains of this species are known to be histamine producers.
• Lactobacillus bulgaricus: Commonly used in yogurt, this strain has been shown to increase histamine levels.
• Streptococcus thermophilus: Also a common yogurt starter culture, some strains can be problematic for those with HIT.
• Lactobacillus helveticus: Some research identifies this species as a potential histamine producer.

Strains to Consider (Histamine-Degrading or Neutral)

Conversely, several probiotic strains are considered safe for a low-histamine diet because they either don't produce histamine or actively help to degrade it.

• Bifidobacterium longum: Excellent for improving the gut barrier and supporting the breakdown of histamine.
• Bifidobacterium infantis: Can help lower histamine levels and support a healthy gut barrier.
• Lactobacillus plantarum: Specific strains have demonstrated the ability to degrade histamine and other biogenic amines.
• Lactobacillus rhamnosus: Research suggests strains like GG and Lc705 can lower histamine levels.
• Lactobacillus gasseri: Identified as a potential histamine-degrader.
• Bifidobacterium breve: Considered a safe, low-histamine option.
• Saccharomyces boulardii: A beneficial yeast that can help restore gut balance without increasing histamine.

A Comparison of Probiotic Strains for Histamine Intolerance

Probiotic Strain	Effect on Histamine	Notes
Lactobacillus casei	High Histamine	Often found in dairy products; can worsen HIT symptoms.
Lactobacillus bulgaricus	High Histamine	Common yogurt starter culture; best avoided in HIT.
Bifidobacterium longum	Low/Degrading	Supports gut barrier and histamine elimination.
Lactobacillus plantarum	Low/Degrading	Certain strains actively break down histamine.
Streptococcus thermophilus	High Histamine	Another common yogurt strain that can increase histamine.
Bifidobacterium infantis	Low/Degrading	Excellent option for promoting healthy gut flora.
Lactobacillus rhamnosus	Low/Degrading	Well-researched strain known for its anti-inflammatory effects.

Tips for Incorporating Safe Probiotics

• Look for Strain-Specific Supplements: The supplement label should list the specific strain, such as Bifidobacterium longum W11, not just the species. Generic labels are best avoided.
• Start Low, Go Slow: Introduce new probiotics gradually to see how your body reacts. Start with a very low dose and increase slowly while monitoring your symptoms.
• Avoid Fermented Foods: While a good source of probiotics for some, fermented foods like sauerkraut, kombucha, and aged cheeses are often high in histamine and can trigger reactions. Probiotic supplements are a safer, more controlled alternative.
• Consider Paraprobiotics: If you are extremely sensitive, inactivated or heat-killed probiotic strains (paraprobiotics) may offer some benefits without the risk of an allergic reaction to the live culture.
• Support Your DAO Enzyme: Supplementation with nutrients that support DAO production, like vitamin B6, magnesium, and zinc, can also help your body manage histamine effectively.

A Broader Approach to Healing the Low-Histamine Gut

For long-term management of histamine intolerance, relying solely on probiotics is not enough. A holistic approach that addresses the root causes of gut imbalance is essential.

Additional Strategies for Gut Support

1. Consume Prebiotic Foods: Prebiotics are non-digestible fibers that feed beneficial bacteria. Good low-histamine options include garlic, onions, and asparagus.
2. Focus on Anti-Inflammatory Foods: Incorporating foods with natural anti-inflammatory properties can help calm the gut lining. Think ginger, turmeric, and fresh, low-histamine fruits and vegetables.
3. Manage Stress: Chronic stress can negatively impact gut health and inflammation. Practices like meditation, yoga, or deep breathing can help regulate your nervous system and support a healthier gut environment.
4. Prioritize Sleep: Adequate, restful sleep is crucial for overall health and supports the body's natural healing processes.

For a deeper scientific dive into the mechanisms connecting gut health and histamine intolerance, consider exploring peer-reviewed articles. Research is increasingly pointing to the gut as a primary origin of histamine issues. For instance, the article “Histamine Intolerance Originates in the Gut” provides a detailed review of this emerging evidence, highlighting the critical role of gut function in managing HIT symptoms.

Conclusion: Navigating Probiotics Safely

The answer to the question, "Can I take probiotics on a low-histamine diet?" is a cautious yes, but only with a strategic approach. It is vital to move beyond generic probiotic recommendations and carefully select strains that are known to be histamine-degrading or neutral, such as certain Bifidobacterium and Lactobacillus strains. Equally important is avoiding common histamine-producing culprits, especially those found in fermented foods. By combining targeted probiotic supplementation with a holistic focus on gut healing, stress management, and supportive nutrients, individuals can safely improve their gut health without worsening their histamine intolerance symptoms. Always consult a healthcare professional, such as a functional medicine practitioner or dietitian specializing in histamine intolerance, for personalized guidance on this complex issue.
