What is Lactobacillus rhamnosus GG?
Lactobacillus rhamnosus GG (LGG) is a specific, well-research ed strain of probiotic bacteria found naturally in the intestines. As a member of the Lactobacillus family, it produces lactic acid and is uniquely adapted to survive and colonize the intestinal walls. Administering LGG introduces beneficial live microorganisms that help restore the balance of the gastrointestinal microflora, inhibit the growth of harmful bacteria, and support immune functions. Its resilience to stomach acid allows it to reach the intestines effectively, where it can provide significant health benefits.
Key Benefits of L. rhamnosus GG
LGG is prized for its numerous health-promoting properties, particularly related to digestive and immune support. Among its most well-documented benefits are:
- Diarrhea Prevention and Treatment: Reduces the duration of infectious diarrhea and protects against antibiotic-associated and traveler's diarrhea by helping to restore healthy gut bacteria.
- Irritable Bowel Syndrome (IBS) Symptom Relief: May alleviate common IBS symptoms like bloating and abdominal pain, though more human research is needed.
- General Gut Health: Improves the overall gut environment by encouraging the growth of other beneficial bacteria and supporting the intestinal barrier.
- Immune System Modulation: Influences immune cells to produce beneficial immune responses, strengthening the body's defenses.
- Prevention of Eczema: Maternal supplementation with LGG during pregnancy and breastfeeding has shown potential in reducing the risk of eczema in infants.
- Oral Health: Fights harmful bacteria that cause dental cavities and gum inflammation.
Understanding Different Forms
The appropriate use of LGG depends on the user's age and the specific health goal. The amount of beneficial bacteria is measured in Colony-Forming Units (CFU), which indicates the number of live, viable bacteria in a serving. It is important to follow the guidance of a healthcare professional regarding the appropriate amount for your needs.
Different Forms of LGG
LGG is widely available in several formats to suit different needs:
- Capsules/Tablets: Swallowed whole with water. Ensure they are designed to protect the bacteria through the stomach.
- Powders: Capsules can be opened to mix the contents into cool food or drinks. Pre-packaged powders are also available, often for children.
- Liquid Drops: A convenient option for infants and small children.
- Fortified Foods: Certain yogurts, cheeses, and milk products may contain LGG to boost their probiotic content. However, check the label for the specific strain and CFU count, as this can vary widely.
Timing Your Dose for Maximum Benefits
While consistency is more important than the exact time, strategic timing can increase the likelihood of the live bacteria surviving the journey to the intestines.
With Food or Without?
- With Food: Taking LGG with a meal that contains some fat can help buffer stomach acid, providing a protective environment for the probiotics. The presence of food can also slow the passage through the stomach, giving the bacteria more time to adapt.
- On an Empty Stomach: Some experts suggest taking probiotics on an empty stomach, typically in the morning, when stomach acid levels are at their lowest. For some strains, this may allow for quicker transit to the intestines. LGG is known for its acid resistance, making timing less critical than with other strains.
Special Considerations for Antibiotics Antibiotics can kill beneficial bacteria alongside the harmful ones they target. To protect your probiotic, take your LGG supplement at least 2 to 3 hours before or after your antibiotic dose. Continue taking the probiotic as directed by a healthcare professional to help restore the gut flora.
Proper Storage and Preparation
To maintain the viability of the live cultures, correct handling and storage are essential. Always follow the product label's instructions, as requirements vary.
General Storage Tips
- Temperature: Many LGG supplements are shelf-stable at cool room temperature, while others require refrigeration. High heat can destroy the bacteria, so avoid storing in warm, sunny locations.
- Moisture: Keep capsules sealed in their blister packs or powder containers tightly closed to prevent moisture exposure.
- Freezing: Never freeze LGG supplements, as this can damage the live cultures.
Preparation Tips
- Capsules: Swallow whole with a cool or room-temperature drink.
- Powders: When mixing a powder into a liquid or food, ensure the medium is cool or room temperature. Heat can kill the live bacteria.
Lactobacillus rhamnosus GG: Supplement Comparison
| Feature | Capsule Supplements (Adults) | Powder Supplements (Children/Adults) | Fortified Dairy (e.g., Yogurt) |
|---|---|---|---|
| Amount Control | Precise CFU count per capsule | Easy to adjust serving size; measured via scoop or sachet | CFU count can vary significantly between brands and batches |
| Ingestion Method | Swallowed whole with water | Mixed with cool food (e.g., applesauce) or drinks | Consumed as part of a meal or snack |
| Viability | Protected by capsule, often delayed-release for better survival | Less protection from stomach acid unless microencapsulated | Survival through digestion may be limited for some products |
| Convenience | Convenient for on-the-go use; no mixing required | Flexible for those who cannot swallow capsules; good for kids | Readily available and palatable; integrated into diet |
| Targeted Use | Specific for adult digestive support, antibiotic-associated diarrhea | Ideal for pediatric use or customized use; specific conditions | General wellness; less potent for targeted therapeutic uses |
How to Choose a Quality LGG Supplement
Selecting a high-quality LGG supplement is critical for ensuring you receive a viable and effective product. Here are some factors to consider:
- Strain Specificity: Look for products that list the exact strain, like L. rhamnosus GG, not just the species. Different strains have different functions.
- Guaranteed Potency: The label should specify the CFU count guaranteed at the expiration date, not just at the time of manufacture.
- Delivery Method: Opt for products with delivery technologies that enhance survival, such as delayed-release capsules or microencapsulated powders.
- Third-Party Certification: Look for seals from independent testing organizations to verify the product's purity and potency.
- Reputable Manufacturer: Choose brands known for quality control and transparency in their manufacturing processes. For example, the well-known brand Culturelle exclusively uses the Lactobacillus rhamnosus GG strain for its proven effectiveness.
Conclusion
Understanding how to take Lactobacillus rhamnosus GG properly can significantly enhance its positive effects on your health. While LGG is a remarkably resilient and effective probiotic, attention to timing and storage is key to maximizing its benefits. Always separate your probiotic intake from antibiotics by at least two hours to ensure the beneficial bacteria survive. Consistency is the most important factor, so find a routine that works for you, whether it's with breakfast or on an empty stomach. Before starting any new supplement regimen, consult with a healthcare professional to determine the right approach for your specific needs.
