Best by Type: Probiotics vs Prebiotics vs Digestive Enzymes
Understanding the different categories of gut health supplements helps you choose the right approach for your specific needs. Each type works through a distinct mechanism, and many people benefit from combining multiple approaches.
Probiotics
Probiotics are live microorganisms that, when consumed in adequate amounts, provide health benefits by adding to the beneficial bacteria populations in your gut. They help maintain microbial balance, support immune function, and may ease digestive discomfort. Look for products with specific strains backed by clinical research, such as Lactobacillus rhamnosus GG (LGG) or Bifidobacterium lactis.
Best for: Restoring gut flora after antibiotics, supporting immune function, managing occasional digestive upset, and maintaining overall gut balance.
Top Pick: Culturelle Digestive Daily Probiotic for its clinically studied LGG strain, or Seed DS-01 for comprehensive multi-strain support.
Prebiotics
Prebiotics are non-digestible fibers that serve as food for beneficial gut bacteria. Common prebiotic fibers include inulin, fructooligosaccharides (FOS), galactooligosaccharides (GOS), and resistant starch. By nourishing your existing good bacteria, prebiotics help them thrive and produce beneficial compounds like short-chain fatty acids.
Best for: Supporting existing gut bacteria, improving regularity, and enhancing probiotic effectiveness when used together (as a synbiotic).
Top Pick: Most high-quality probiotics now include prebiotic fiber. Look for products containing organic potato starch, acacia fiber, or inulin.
Digestive Enzymes
Digestive enzymes help break down food into absorbable nutrients. Key enzymes include amylase (carbohydrates), protease (proteins), and lipase (fats). Some people may benefit from supplemental enzymes if their bodies don’t produce adequate amounts, or when eating foods that challenge digestion.
Best for: Those experiencing bloating or discomfort after meals, people with reduced enzyme production, and anyone eating foods they have difficulty digesting (like dairy for lactose-intolerant individuals).
Top Pick: NOW Foods Super Enzymes for its comprehensive enzyme blend including betaine HCl and ox bile.
Gut Lining Support (L-Glutamine and Botanicals)
The intestinal lining serves as a critical barrier between your digestive tract and bloodstream. L-glutamine is the primary fuel source for intestinal cells and may help maintain gut barrier integrity. Botanical ingredients like slippery elm, marshmallow root, and DGL licorice provide soothing support for the digestive tract.
Best for: Those focused on intestinal barrier function, individuals under physical stress, and anyone seeking targeted gut lining support.
Top Pick: Amy Myers MD Leaky Gut Revive for comprehensive gut lining support, or Thorne L-Glutamine Powder for pure, NSF-certified L-glutamine.

Buying Guide: What to Look for in Gut Health Supplements
Key Quality Indicators
Third-Party Testing: Look for supplements tested by independent labs for purity, potency, and contaminants. Certifications like NSF, USP, or ConsumerLab approval provide additional assurance.
Strain Specificity: Quality probiotics list specific strains (e.g., Lactobacillus rhamnosus GG), not just species. Different strains of the same species can have very different effects.
CFU Guarantee at Expiration: Reputable brands guarantee CFU counts through the expiration date, not just at time of manufacture. Probiotic potency decreases over time.
Appropriate CFU Count: More isn’t always better. Research supports benefits at various potency levels. For general maintenance, 5-30 billion CFU is often sufficient. Higher counts (50-100+ billion) may benefit those with specific concerns.
Certifications That Matter
NSF Certified for Sport: Indicates testing for banned substances and label accuracy—important for athletes and a good quality indicator for everyone.
Non-GMO Project Verified: Confirms the product meets strict non-GMO standards.
Third-Party Testing: Independent verification of contents and purity by labs like ConsumerLab, USP, or NSF.
Red Flags to Avoid
Proprietary Blends Without Strain Details: If a product lists a “probiotic blend” without specifying strains and individual CFU counts, you can’t evaluate its potential effectiveness.
Unrealistic Claims: Be wary of products claiming to cure diseases or making dramatic promises. Supplements can support health but aren’t treatments for medical conditions.
Lack of Storage Instructions: Quality probiotics will specify whether refrigeration is required. Products that ignore this important detail may not maintain potency.
Very Low Pricing: Extremely cheap probiotics may cut corners on quality, sourcing, or testing. Effective probiotics require proper manufacturing and storage.
Form Selection Guidance
Capsules: Most common form. Look for acid-resistant or delayed-release capsules that protect probiotics through stomach acid.
Powders: Good for customizable dosing and those who have difficulty swallowing capsules. Can be mixed into beverages or food.
Gummies: Convenient and palatable but may contain added sugars. Heat and moisture during manufacturing can reduce probiotic viability.
Refrigerated vs. Shelf-Stable: Modern manufacturing has made many probiotics stable at room temperature. Shelf-stable products offer convenience without sacrificing quality when properly formulated.
How to Take Gut Health Supplements
Recommended Dosages
Follow the manufacturer’s directions, as optimal dosing varies by product. General guidelines include 5-30 billion CFU for daily maintenance, higher amounts (50-100+ billion) for specific concerns, and 3-5 grams daily for L-glutamine supplements. More isn’t always better—start at recommended doses and adjust based on response.
Best Time to Take
Research on timing is mixed, but general guidance suggests that probiotics may be taken with or without food, though some studies suggest taking them with meals improves survival. L-glutamine is often recommended on an empty stomach for better absorption. Digestive enzymes should be taken with the first bite of food. Consistency matters more than perfect timing—take supplements when you’ll remember them daily.
Usage Instructions for Different Forms
Capsules: Swallow with water. Some can be opened and mixed into cool beverages or soft foods if swallowing is difficult.
Powders: Mix into room temperature or cool water, juice, or smoothies. Avoid hot beverages that could damage live cultures.
Chewables/Gummies: Chew thoroughly before swallowing.
Duration and Cycling Recommendations
Most people can take probiotics indefinitely as part of their wellness routine. Some practitioners recommend rotating probiotic strains every few months to encourage microbiome diversity. If taking probiotics to address a specific issue, give them at least 4-8 weeks to assess effectiveness. L-glutamine can be taken continuously or cycled based on individual needs and practitioner guidance.
Potential Benefits of Gut Health Supplements
Digestive Health
Research suggests probiotics may help maintain digestive comfort, support regular bowel movements, and ease occasional bloating and gas. A meta-analysis published in the World Journal of Gastroenterology found certain probiotic strains may help manage symptoms of irritable bowel syndrome. Digestive enzymes may aid nutrient breakdown and absorption, particularly for those with reduced enzyme production.
Immune Function
Approximately 70% of the immune system resides in the gut. Studies suggest probiotics may support immune function by maintaining gut barrier integrity and promoting beneficial immune responses. A 2019 review in Nutrients found probiotic supplementation may reduce the duration and severity of respiratory infections.
Gut Barrier Support
L-glutamine serves as the primary fuel source for intestinal cells and may help maintain tight junctions between cells. Research in Clinical Nutrition found glutamine supplementation may help support intestinal permeability in conditions involving gut barrier stress.
Mental Health Connection
The gut-brain axis represents bidirectional communication between the digestive system and brain. Emerging research suggests certain probiotic strains (sometimes called “psychobiotics”) may influence mood and cognitive function, though this field requires more study.
Safety Considerations
Potential Side Effects
When starting probiotic supplements, some people experience temporary digestive adjustments including bloating, gas, or changes in bowel movements. These typically resolve within 1-2 weeks as the gut adapts. Starting with a lower dose and gradually increasing may minimize these effects.
Digestive enzymes are generally well-tolerated but may cause nausea or diarrhea in some individuals, particularly at higher doses.
L-glutamine is considered safe at typical supplemental doses (up to 40g daily in research settings), though excessive amounts may affect ammonia metabolism.
Who Should Exercise Caution
Immunocompromised Individuals: Those with weakened immune systems should consult healthcare providers before taking probiotics, as rare cases of infection have been reported.
Those on Medications: Some supplements may interact with medications. Digestive enzymes may affect medication absorption. Always consult a healthcare provider if taking prescription medications.
Pregnant or Nursing Women: While many probiotic strains are considered safe during pregnancy, it’s best to consult a healthcare provider before starting any supplement.
Those with Serious Digestive Conditions: People with inflammatory bowel disease, SIBO, or other significant gut conditions should work with healthcare providers to determine appropriate supplementation.
Drug Interactions
Probiotics are generally safe alongside most medications, though timing may matter—take them at least 2 hours apart from antibiotics. Digestive enzymes may affect absorption of certain medications. L-glutamine may interact with some anti-seizure medications. Always inform healthcare providers about supplements you’re taking.
Frequently Asked Questions
How long does it take to notice benefits from probiotics?
Some people notice changes within a few days, while others may need 4-8 weeks of consistent use. Factors including your starting gut health, the specific probiotic strains, and your diet can influence how quickly you respond. Consistency is key—daily use over time yields the best results.
Can I take probiotics with antibiotics?
Yes, and research suggests this may help reduce antibiotic-associated digestive issues. Take probiotics at least 2-3 hours apart from antibiotic doses and continue for at least two weeks after completing the antibiotic course. Saccharomyces boulardii is a yeast-based probiotic that isn’t affected by antibiotics.
Do I need to refrigerate my probiotics?
It depends on the product. Many modern probiotics are shelf-stable when properly formulated. Check the label for storage instructions. If refrigeration is recommended, follow those guidelines to maintain potency.
What’s the difference between CFU and AFU?
CFU (Colony Forming Units) is the traditional measure of viable bacteria. AFU (Active Fluorescent Units) is a newer measurement that some brands use, particularly Seed. Both indicate the number of live microorganisms, though the measurement methods differ.
Should I take probiotics on an empty stomach?
Research is mixed. Some studies suggest taking probiotics with meals improves survival through stomach acid, while others show no significant difference. The most important factor is consistency—take them when you’ll remember to do so daily.
Can probiotics help with weight management?
Emerging research suggests certain probiotic strains may influence metabolism and appetite, though results are preliminary. Probiotics alone are unlikely to cause significant weight loss but may be one component of a comprehensive approach to healthy weight management.
Are more CFUs always better?
Not necessarily. Clinical studies have shown benefits at various potency levels. The right amount depends on your specific needs, the particular strains involved, and your current gut health. Starting with moderate doses (10-30 billion CFU) and adjusting based on response is a reasonable approach.
Can I take multiple gut health supplements together?
Yes, many people combine probiotics with digestive enzymes or L-glutamine for comprehensive support. Synbiotic formulas already combine probiotics and prebiotics. Consider your specific needs and avoid unnecessary redundancy.
How do I know if a probiotic is working?
Signs that probiotics may be helping include more regular bowel movements, reduced bloating or gas, improved energy levels, and better overall digestive comfort. Keep in mind that some people notice subtle rather than dramatic changes.
What’s the best probiotic for bloating?
Bifidobacterium strains (particularly B. lactis and B. infantis) have shown promise for reducing bloating in clinical studies. Multi-strain formulas that include these, such as Seed DS-01 or Garden of Life products, may be good options. Digestive enzymes can also help if bloating is related to food breakdown.
