Probiotics are tiny living creatures called "good bacteria" that live in our stomach and intestines. They help us digest food, absorb nutrients, and keep our gut healthy. Sometimes, things like eating too much junk food, getting sick, or taking antibiotics can upset the balance of these good bacteria.
When this happens, bad bacteria can take over, causing stomachaches, diarrhea, or constipation. Probiotics help by adding more good bacteria back into our bodies. They fight off the bad bacteria and make sure our digestive system works well.
Good bacteria also help our immune system, which is what keeps us from getting sick. They make a barrier in our gut that stops harmful germs from getting into our bodies.
In short, we need probiotics to keep a healthy balance of bacteria in our stomachs. This helps us feel good, digest our food properly, and stay healthy.
That’s why we’re here. We researched the top selling probiotics supplements on the internet and made purchases to test some of 2024’s most talked about probiotics products. We combed through the scientific research and interviewed beauty specialists and probiotics experts*
Some of the supplmements we were informed could even make your hair, skin and nails worse which is why you need to keep reading to make sure you get the scoop on what we discovered.
Benefits of a High Quality Probiotic for Gut Health and Digestion
-
Easier Digestion and Less Bloating
-
Promotes Regularity
-
Prevents Diarrhea and Constipation
-
Supports Immune Function
-
Boosts Gut Health
A high-quality probiotic is like a team of strong helpers for your stomach. It has the right kinds of good bacteria that can survive the trip through your stomach to reach your intestines.
These probiotics can make digestion easier, so you might have less gas, bloating, or stomach aches. They can help if you're having trouble going to the bathroom by making things more regular.
High-quality probiotics are made carefully to make sure the good bacteria stay alive until you take them. This makes them work better than ones that aren't made as well.
Probiotics FAQ
How Long Do Probiotics Take to Work?
Some people might notice a difference in just a few days, especially if they had stomach problems like diarrhea. For other issues, like long-lasting stomachtroubles, it might take a few weeks or even a couple of months to see big changes. It's important to take probiotics every day so the good bacteria can build up in your gut. Eating healthy foods like fruits, vegetables, and whole grains can help the probiotics work better.
Which Strains are Important?
There are many kinds of good bacteria, called strains, that can help your stomach. Here are some important ones to look for:
- Lactobacillus acidophilus: Helps you digest food and can make it easier to eat dairy products without getting a stomachache.
- Lactobacillus plantarum: Research indicates it might have anti-inflammatory effects in the gut, potentially supporting digestive health.
- Lactobacillus rhamnosus: Effective for people with diarrhea, especially if you're traveling or have taken antibiotics.
- Bifidobacterium lactis: Helps break down the food you eat and can reduce inflammation in your gut.
When choosing a probiotic, check the label to see which strains it has. Picking one with the right strains for your stomach troubles can make it work better for you.
Are CFU Counts Important?
The dose of probiotics tells you how many good bacteria you're getting. This is measured in something called CFUs, which stands for "colony-forming units." It's like counting how many helpful bacteria are in each pill or serving
Having enough CFUs is important because you need a certain number of good bacteria to make a difference in your stomach. For general health, a probiotic with 10 to 20 billion CFUs is usually good. If you have bigger stomach problems, you might need more.
Why Probiotics Alone are Not Enough
Every top class probiotic supplement should include a prebiotic and a postbiotic. Both work in tandem to enhance the performance of the probiotics and any supplement which includes one or both of these has been well formulated.
Prebiotics are non-digestible food ingredients typically fibers like inulin, fructooligosaccharides (FOS), and galactooligosaccharides (GOS) which serve as food for beneficial gut bacteria (probiotics). By nourishing these good bacteria, prebiotics help maintain a balanced gut microbiome.
Postbiotics strengthen the intestinal lining, reducing permeability ("leaky gut") and preventing harmful substances from entering the bloodstream.
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.
