Prebiotic and probiotic supplements are best known for improving gut health, but their benefits extend far beyond digestion. Studies show they can help manage specific conditions — from bloating and constipation to immunity and skin health.
However, results depend on choosing the right strains and prebiotic fibres, taking them consistently, and pairing them with a balanced diet.
In this guide, we’ll explore how prebiotics and probiotics work for different health concerns, what science says about their benefits, and how to select the right supplement for your needs.
How Prebiotics and Probiotics Work Together
- Probiotics are live beneficial bacteria that help restore and maintain the balance of your gut microbiome.
- Prebiotics are non-digestible fibres that act as food for probiotics, helping them multiply and thrive.
When combined, they form a synbiotic — a partnership where prebiotics nourish probiotics, making them more effective. This combination can be found in high-quality products like Progud Prebiotic & Probiotic, which delivers both in one convenient formula.
📖 For a complete breakdown of how they differ, read our guide on Prebiotic vs Probiotic Supplements.
1. Bloating and Gas
Bloating is one of the most common digestive complaints. It can be caused by:
- An imbalance in gut bacteria
- Poor digestion of certain foods (e.g., beans, dairy, gluten)
- Excessive fermentation in the colon
Probiotic benefits for bloating:
- Strains like Bifidobacterium lactis HN019 and Lactobacillus acidophilus can improve gut motility, helping food move through the digestive tract more efficiently.
- Saccharomyces boulardii may help reduce gas production from imbalanced gut flora.
Prebiotic benefits for bloating:
- Prebiotics like inulin and galactooligosaccharides (GOS) feed healthy bacteria, but in sensitive individuals, too much too quickly can temporarily increase bloating.
- Gradual introduction is key — start with a lower dose and increase over time.

2. Constipation
Constipation can result from low fibre intake, dehydration, stress, or disrupted gut bacteria.
Probiotics for constipation:
- Strains like Bifidobacterium lactis BB-12 and Lactobacillus casei Shirota help soften stools and increase bowel movement frequency.
Prebiotics for constipation:
- Fibres like fructooligosaccharides (FOS) and partially hydrolysed guar gum increase stool bulk and water content.
- Prebiotics also stimulate fermentation, producing short-chain fatty acids (SCFAs) that support intestinal health.
A synbiotic formula like Progud can offer a dual benefit: probiotics restore gut balance, while prebiotics improve stool consistency.
3. Diarrhoea
Diarrhoea may occur due to:
- Viral or bacterial infections
- Antibiotic use (antibiotic-associated diarrhoea)
- Food intolerances
Probiotics for diarrhoea:
- Saccharomyces boulardii and Lactobacillus rhamnosus GG are the most researched for reducing diarrhoea duration and restoring gut balance after antibiotics.
Probiotics for diarrhoea:
- Can help maintain gut microbiome diversity and support faster recovery, especially after antibiotic treatment.
📌 For overall gut support during recovery, see our article on Gut Health and Prebiotic & Probiotic Supplements.
4. Immune System Support
About 70% of the immune system is located in the gut-associated lymphoid tissue (GALT).
How probiotics help immunity:
- Stimulate immune cells (macrophages, T lymphocytes)
- Reduce inflammation and support a balanced immune response
How prebiotics help immunity:
- Encourage the growth of beneficial bacteria that produce SCFAs, which regulate immune function
- May enhance the effectiveness of vaccinations and reduce respiratory infection risk in some individuals
5. Skin Health & Allergies
The gut-skin axis links gut microbiota health to skin conditions.
Probiotic benefits:
Certain strains (Lactobacillus rhamnosus GG, Bifidobacterium breve) may reduce eczema risk in infants and improve skin hydration in adults.
Prebiotic benefits:
Feeding beneficial bacteria can indirectly lower systemic inflammation, which plays a role in acne and other skin issues.
6. Women’s Health
For women, probiotics and prebiotics can play a role in both digestive and reproductive health.
Probiotic benefits for vaginal health:
Lactobacillus reuteri and Lactobacillus rhamnosus help maintain a healthy vaginal microbiome, reducing the risk of yeast infections and bacterial vaginosis.
Prebiotic support:
Some prebiotics can support the growth of vaginal lactobacilli when taken orally.
Choosing the Right Supplement for Your Needs
When picking a prebiotic & probiotic supplement:
- Check the strain — Look for strains researched for your specific condition.
- Consider the CFU count — A minimum of 1 billion CFU per serving is recommended.
- Opt for a synbiotic — A formula like Progud provides both prebiotics and probiotics in one capsule.

How to Take Them for Best Results
- Consistency is key — Take daily for 4–8 weeks before assessing results.
- Timing — Probiotics are often best on an empty stomach; prebiotics can be taken with meals.
- Diet pairing — Combine with natural sources like yogurt, kefir, garlic, onions, and bananas for maximum benefit.
