Probiotics are beneficial microorganisms that maintain gut health by balancing your microbiome. When this balance is disrupted by poor diet, stress, or antibiotics, it can lead to gut issues and weakened gut barriers.
We researched the market's top probiotics, tested the most popular formulas, and consulted with health experts to bring you this definitive guide.
Benefits of High-Quality Probiotics for Gut Health
-
Restores Gut Microbiome Balance
-
Strengthens Intestinal Barrier
-
Reduces Inflammation
-
Improves Nutrient Absorption
-
Supports Immune Function
Key Considerations - Important
Important Strains: There are many kinds of good bacteria, called strains, that can help your gut. Here are some important ones to look for:
-
Lactobacillus acidophilus : Supports overall gut health and aids digestion.
-
Lactobacillus plantarum : Helps maintain intestinal barrier integrity.
-
Lactobacillus rhamnosus : Effective for various digestive conditions.
-
Bifidobacterium lactis : Improves digestive comfort and regularity.
-
Bifidobacterium longum : Supports gut microbiome diversity.
-
Bifidobacterium bifidum : Enhances gut barrier function.
-
Lactobacillus casei : Promotes beneficial gut bacteria balance.
CFU Count: Look for at least 10-30 billion CFUs for maintenance, 50-100 billion for specific issues.
Complete Formula: The best supplements include prebiotics (to feed good bacteria) and postbiotics (beneficial compounds that support gut health directly).
What To Avoid:
Low Potency Probiotics
We do not reccomend any probiotic with a daily dose of less than 10 Billion CFU as many of the probiotics will die on their way to the gut
No Delayed Release Capsule
Delayed release capsules allow the probiotics to survive longer on their way down to the gut and any brand which does not include this should not be considered.
Relying on Amazon reviews
60% of reviews are written by folks paid to leave positive feedback. Risking your health with reviews that are false is too dangerous a game to play when choosing a supplement.
With these guidelines in mind, we scoured the market for the best of the best probiotics supplements.

2. Protectis
by Bio Gaia
7.8
Total Ranking
- Chewable Tablets
- 3 Month Supply
- Contains Bulking agent (isomalt)
- Contains sweetener (xylitol),
- Not made in the UK
- Only 1 strain of Probiotic
- Does not use a delayed release capsule
The Bottom Line
Coming in at a close second is Protectic probiotics by Bio Gaia. There is a lot to like about this product, including the fact it contains chewable tablets for those who struggle to swallow capsules.
Unfortunately it does contains a bulking agent (isomalt) and sweetner which we generally frown apon.
3. Pro Bio Clutures
by Weightworld
6.9
Total Ranking
- Made in the UK
- Contains a prebiotic (Organic Inulin Powder)
- Anti-Caking Agent: Magnesium Stearante
- Does not use a delayed release capsule
- Poor value £53.99 for 10 day supply at 5000mg a day dose
The Bottom Line
Coming in 3rd on the market is Gold Forte probiotics by Minerva Labs
Gold probiotics Forte delivers a 5000mg daily dose and includes quite few of the synergistic ingredients we like such as Vitamin C, Hyaluronic Acid, Zinc and Copper
However we do not like the fact that they sell this product in a 10 bottle pack at £53.99 and each dose only delivers 5000mg which presents poor value.
Their probiotics source is also not declared on the website
4. probiotics Hydro Pro+
5.3
Total Ranking
- Easy-To-Swallow Capsules
- Contains Vitamin C and Hyaluronic Acid
- probiotics sourced from Wild Caught Fish
- Tablet form poorer than liquids or Powders
- Daily dose only 1000mg
The Bottom Line
Nutraherbal's ashwagandha is both organically grown and free of gluten, soy, and GMOs. While it contains a potent dose of ashwagandha, unfortunately, it does not use a clinically studied version. Additionally, it lacks L-theanine.
On the plus side, it contains black pepper extract to better help with absorption. They don't use any binders and reviewers reported positive benefits after use, however their return policy is unspecified.
5. Marine probiotics Capsules
by Superself
5.3
Total Ranking
- Low price
- Positive customer reviews
- Non-GMO
- Third-party tested
- Does not use clinically studied marine probiotics
- Lacks Ginseng
- Only 60-day return policy
The Bottom Line
Havasu Nutrition's rounds out our list with their probiotics supplement. Reviewers raved about the low price and that it contains no preservatives, chemicals, or sugars.
However, this product does not use a clinically studied form of probiotics and it also lacks L-theanine. They also boast a unique artichoke extract to help with both absorption and digestion.
