The probiotic supplement Culturelle, which contains the well-researched strain Lactobacillus rhamnosus GG (LGG), is widely considered safe for most people when used as directed. Its purpose is to help restore the balance of beneficial bacteria in the gut. However, as with any supplement, some individuals may experience side effects. Understanding these potential effects, both common and rare, is crucial for safe and effective use.
Common Digestive Discomforts
When first starting a probiotic, it is not uncommon for the digestive system to undergo a temporary adjustment period, which can lead to minor side effects. These issues typically resolve with continued use as the gut's bacterial balance stabilizes.
Gas and Bloating
The most frequently reported side effects are gas (flatulence) and bloating. The introduction of new bacteria into the gut microbiome can alter the fermentation process, leading to a temporary increase in gas production. This usually subsides within a few days or weeks as your body gets used to the supplement.
Stomach Upset
Some users have reported other mild digestive symptoms such as upset stomach, nausea, or mild cramps. These are generally minor and infrequent. If they persist or worsen, consulting a healthcare provider is recommended.
Rare and Severe Side Effects
While Culturelle is safe for most healthy individuals, certain rare but serious risks exist, especially for specific populations. If you experience any of the following, seek medical attention immediately.
Allergic Reactions
A severe allergic reaction to any supplement is rare, but possible. Signs of an allergic reaction may include:
- Rash, hives, or itching
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing or tightness in the chest
- Dizziness
- Unusual hoarseness If any of these symptoms occur, stop taking the supplement and seek emergency medical help. It is also important to note that some Culturelle products may contain trace amounts of allergens like milk or soy, and individuals with severe sensitivities should check the label.
Risks for Immunocompromised Individuals
This is a critical consideration for those with weakened immune systems due to conditions like HIV/AIDS, cancer (especially during chemotherapy), or post-organ transplant medication. The live bacteria in probiotics could, in rare instances, cause an infection in these individuals. Similarly, those with short bowel syndrome or central lines are at a higher risk of developing infections. It is essential for these groups to consult a healthcare provider before using any probiotic supplement.
Comparison of Culturelle Side Effects
| Feature | Common Side Effects | Serious Side Effects |
|---|---|---|
| Nature | Mild and temporary digestive adjustments | Severe, rare, and potentially life-threatening |
| Symptoms | Gas, bloating, intestinal gurgling, mild stomach upset | Severe allergic reactions (hives, swelling), rare infections in at-risk groups |
| Onset | Usually at the start of supplementation | Can occur at any point, but are very infrequent |
| Risk Factors | Natural adjustment process for most individuals | Weakened immune system, central lines, short bowel syndrome, certain allergies |
| Action | Typically resolves with continued use; consult a doctor if persistent | Immediately discontinue use and seek medical attention |
How Culturelle Interacts with Other Medications
Before taking Culturelle or any probiotic, it is important to consider how it might interact with other medications, especially those that can affect bacterial populations.
Antibiotics
Antibiotics are designed to kill bacteria, and they do not differentiate between harmful and beneficial strains. Taking Culturelle too close to an antibiotic dose can render the probiotic ineffective, as the LGG bacteria may be killed off. It is recommended to take your Culturelle dose at least 2 to 3 hours before or after you take your antibiotic.
Immunosuppressants
Medications that suppress the immune system, such as those used for cancer treatment or organ transplants, increase the risk of infection from the live bacteria in probiotics. If you are on these medications, you should not take Culturelle without prior consultation with your healthcare provider.
Who Should Take Culturelle with Caution?
While most people can take Culturelle safely, certain individuals need to exercise caution and should consult a doctor before beginning supplementation. This list includes, but is not limited to:
- Individuals with a weakened immune system: As discussed, this includes people with conditions like HIV/AIDS or those undergoing chemotherapy.
- Those with severe digestive tract diseases: People with short bowel syndrome or gastrointestinal perforation are at an increased risk of infection and should be medically advised.
- Patients with central lines: There is a documented risk of blood infection from probiotics in people with central lines.
- Individuals with certain allergies: While some Culturelle products are free of common allergens like gluten, some may contain milk or soy ingredients. Check the specific product label for any potential allergens.
- Pregnant and breastfeeding women: While some studies show LGG is likely safe, other types of lactobacillus have not been studied as extensively. A doctor's consultation is advised.
- Individuals with diabetes or phenylketonuria (PKU): Some products, especially chewable tablets, may contain sugar or aspartame. Always check the label.

Conclusion
For the vast majority of healthy adults and children, the probiotic supplement Culturelle is a safe product with mild, temporary digestive side effects like gas and bloating. These symptoms often indicate that the gut is adjusting and tend to resolve with consistent use. However, a small subset of the population, particularly those who are immunocompromised or have serious health conditions, face a rare but more significant risk of infection and should always consult a healthcare professional before use. Furthermore, anyone experiencing signs of a severe allergic reaction should stop taking the supplement and seek immediate medical help. By being aware of these potential side effects and following appropriate precautions, most users can safely enjoy the digestive health benefits of Culturelle.
