Our guts produce 95% of that much-needed serotonin from plasma. This endorphin regulates our central nervous system, mindset, and immune health, so keeping a happy gut is key.

That’s where probiotic supplements come in, claiming to increase and balance good bacteria levels to maintain optimal gut health. But with so many brands available in today’s market, how do we know which ones are most effective?

To help you find the answer, I took a closer look at YourBiology Gut+ probiotics and gave my opinion from a medical point of view. Read this YourBiology review to find out how they work, their pros and cons, and whether the probiotic supplements compare to the competition.

Created with the help of top scientists and nutritionists, YourBiology is a daily-use probiotics supplement formulated specifically for female health.

The product contains 4 strains of beneficial bacteria to help you achieve great gut health and is packed full of 40 billion colony-forming units (CFUs). This indicates the number of beneficial bacteria cells you’ll receive from YourBiology Gut+.

By feeding these strains, prebiotics within the formula boost its effectiveness, while unique Maktrek Bi-Pass technology protects the bacteria from harsh stomach acid.

This probiotic supplement targets smooth digestion, healthy bacteria maintenance, and improved bowel movements. Nourishing your gut has further perks, like improved skin health and energy, all of which YourBiology targets.

Why I’ve Decided to Review YourBiology

With a huge number of probiotics brands promising that their supplement helps users to achieve weight loss, improved digestion, and a strengthened gut lining, it’s often difficult to decide which one to choose. 

This is the case for many of my patients struggling with gastrointestinal symptoms, who often ask for my opinion on probiotics.

While exploring the options, YourBiology Gut+ caught my eye as it offers a 250 times better survival rate for its probiotic strains than other supplements. This is thanks to the capsules’ brown seaweed coating, which provides safe passage for the beneficial bacteria as it travels to the small intestine. 

I wanted to put this claim to the test, so I ordered a bottle, looked at the ingredients, and made a judgment on whether or not this supplement could provide a solution for poor gut health.

How Does YourBiology Work?

As I mentioned, YourBiology Gut+ is made with 4 live probiotic strains that are proven to be effective in supporting your overall gut health. Two of these strains are Lactobacilli, a species that produces lactic acid to strengthen the intestines and prevent bad bacteria from colonizing the gut.

The other species I was pleased to see on the YourBiology ingredients list is Bifidobacteria, which create short-chain fatty acids that play an important role in good gut health, controlling appetite, and producing essential B vitamins.

To experience these benefits, it’s recommended to take 2 capsules per day: 1 in the morning and 1 in the evening.

Remember that every user’s experience with these probiotics is likely to be different, so how YourBiology works for one customer may not be the same for you. This is because everyone’s gut microbiome operates differently based on their unique genetics, diet, exercise routine, and even where they live. 

However, the company does suggest that you should see visible changes in your digestion, mood, and overall well-being within 60 days of purchase; otherwise, you’ll be able to get your money back.

How Does YourBiology Stand Out From Competitors?

When selecting a product to review, what made YourBiology leap off the shelf at me was the fact that it is made with a marine polysaccharide complex, which is patented by the brand as their unique Maktrek technology.

This is a type of capsule protection that allows the probiotics to reach the small intestine safely without encountering damage from stomach acid. Many other formulas I’ve looked at lack this protection, making them a waste of time and money. 

The ratio of 40 billion colony-forming units (CFUs) held in YourBiology Gut+ probiotic capsules is another competitive advantage. Although supplements only need around 10–20 billion CFUs to be effective, this makes YourBiology ideal for those with health conditions like irritable bowel syndrome (IBS) who require stronger probiotics to tackle the symptoms.

The brand’s inclusivity is a further competing factor. YourBiology markets the product as free of dairy, soy, and gluten, making it compatible with many diets.

YourBiology Gut+ Ingredients

YourBiology Gut+ supplements contain 4 clinically proven bacteria strains derived from natural sources to protect your stomach’s lining. Here are the primary ingredients YourBiology uses:

Proprietary blend of Probiotic Bacteria Maktrek®

YourBiology incorporates innovative Maktrek® Bi-Pass technology to help capsules survive stomach acid or enzyme erosion so our bodies can absorb the capsules’ nutrients. It works by keeping the capsule intact as it passes through the stomach.

Lactobacillus acidophilus

You’ll commonly find lactobacillus acidophilus in your intestines, mouth, and vagina, making this an excellent option for women or those assigned female at birth. This probiotic strain effectively treats bacterial vaginosis, eczema, yeast infections, and symptoms of diarrhea like excess gas, cramps, and bloating.

Bifidobacterium lactis

Bifidobacterium lactis are potent bacterial strains found throughout the human gut. Research shows that Bifidobacterium lactis helps the body absorb vitamins and minerals while also providing a strong defense against gut-based pathogens.

Lactobacillus plantarum

The Lactobacillus plantarum strain included in YourBiology Gut+ balances the gut microbiome, strengthens the intestinal lining, and helps to create a barrier against bad bacteria. Subsequent advantages include relief from irritable bowel syndrome (IBS), decreased bloating, and eased cramping.

Lactobacillus paracasei

Derived from lactic acid bacteria, Lactobacillus paracasei can boost gut health by producing short-chain fatty acids, making it ideal for treating diarrhea. The strain is also useful for protecting the vaginal flora, which it does by preventing the colonization of harmful bacteria in this area.

Marine polysaccharide complex

Marine polysaccharide is a brown seaweed extract that acts as a protective shield for YourBiology’s 4 probiotic species. Consuming this extract has several other benefits, including decreased blood pressure and blood sugar and anti-viral and anti-inflammatory functions.


Fructooligosaccharide is a soluble dietary fiber and prebiotic that boosts the effectiveness of YourBiology Gut+ probiotics. As a source of fiber, including it in this supplement helps to nourish the gut and alleviate constipation

4 Benefits of YourBiology

After looking at the ingredients and research surrounding each one, below I’ve summarized my thoughts on how YourBiology may benefit you:

#1 Improved digestive health

YourBiology Gut+ Probiotics strengthen your digestive tract’s lining, helping you to break down fibers, glucose, and heavier proteins that your body may struggle to digest naturally. This can reduce gastrointestinal symptoms such as bloating, cramps, and excess gas.

#2 Immune function support

Combining 4 dominant probiotics, YourBiology enhances immune health at the gut’s core. This is because the gut contains cells that create antibodies, which help to defend against bacteria, viruses, and other toxins.

Good gut health, therefore, boosts your body’s ability to fight off illness and infection.

#3 Reduced digestive discomfort

If you find yourself experiencing frequent bloating, excess gas, stomach cramps, constipation, or diarrhea, then YourBiology’s 4 probiotic strains may be an effective solution for you.

Along with relieving these symptoms, studies show that supplements made with Lactobacillus are useful for those suffering from digestive disorders such as clostridium difficile (C. diff), ulcerative colitis, Crohn’s disease, and IBS.

#4 Enhanced gut microbiome

YourBiology supplement floods your body with good probiotics such as Lactobacilli and Bifidobacterium, which repopulate the gut and help to create a good bacterial balance. Not only does this help with digestion, but a healthy gut flora is also proven to reduce fatigue, boost your mood, and treat anxiety and depression.

4 Downsides of YourBiology

Here’s what I didn’t love about YourBiology Gut+:

#1 Might cause mild digestive discomfort

During the first month, the sudden intake of a probiotic supplement may shock your system, causing some mild side effects. For example, you may experience discomfort such as bloating, gas, nausea, and diarrhea as you re-regulate your toilet habits.

#2 May interact with some medications

I like the fact that YourBiology probiotics are clinically tested, natural, and safe. However, they aren’t suitable for everyone, particularly those on certain medications. 

There are several reasons why interactions with prescription drugs can occur, but this is mainly because they may stop medications from being absorbed by the gastrointestinal tract, therefore, reducing their efficacy. 

#3 Efficacy might differ

The effectiveness of YourBiology Gut+ will depend on individuals’ genes, conditions, and allergens. For example, a lactose intolerant person may have a different experience than someone without. Consult with your doctor if you experience more severe side effects or if you’re still unsure about whether YourBiology is safe and effective for you.

Does YourBiology Work?

After reviewing the ingredients and reading other customer reviews of YourBiology Gut+, overall, I feel that the probiotic is a natural, safe, and effective treatment for promoting a healthy gut microbiome. 

For instance, as I’ve already mentioned in this review, Bifidobacterium helps the body absorb nutrients that are essential for good digestion, while the various Lactobacillus species work together to strengthen the gut lining against harmful pathogens, repopulate your body with gut good bacteria, and ease gastrointestinal symptoms.

Plus, the Maktrek technology helps all of these beneficial bacteria reach the gut without encountering harmful stomach acid, ensuring that the supplement is effective in its purpose.

YourBiology may be particularly effective for women, as the Lactobacillus strain promotes good vaginal health by balancing pH levels.

However, something that I remind all of my patients when taking probiotics is that they may not necessarily work for you. Although the brand indicates that users should see results in as little as 7 days to 2 weeks, some customers with different genes, diets, and lifestyles may struggle to identify changes at all.

How Long Should You Take YourBiology Gut+ Probiotics to See Results?

When it comes to probiotic supplements like YourBiology, it’s likely that every person’s experience will be slightly different. However, according to YourBiology, if you take 2 capsules per day consistently, you should expect to see results within just 2 weeks. 

Here’s a more detailed timeline of what to expect:

  • 2 weeks – Your gut microbiome should start to balance out, which brings results such as less bloating, better digestion, clear skin, and improved mood
  • 1 month – Bigger health improvements, including regulated bathroom habits, stronger immune function, enhanced mental clarity, and even some weight loss.
  • 3 months and beyond – Your body should now be used to the formula, and as a result, you’ll have fewer sick days, your thoughts will feel clearer, you’ll notice that your mood is lifted, and your digestion should be completely improved.

If you don’t see results within 60 days of regular use, you’ll be able to claim a full refund for the product.

YourBiology Gut+ Cost

One thing I noticed about YourBiology probiotics is that they are pretty expensive compared to the competition. However, the company does often offer discounts on its official website, and you can split the payments into installments with Afterpay to make it more budget-friendly.

Along with the prices below, YourBiology offers free shipping and a 60-day money-back guarantee for unsatisfied customers.

AmountOriginal priceDiscounted price
2-month + 1-month for free$239.99$129.99
3-month + 2-months for free$399.95$194.99


Is YourBiology Gut+ legit?

YourBiology is a legit probiotic and prebiotic supplement provider that is certified for its Good Manufacturing Practices (GMP). It provides safe and clinically-tested formulas with several natural probiotic strains that are scientifically proven to be effective in boosting immune, vaginal, and gut health.

Where to buy YourBiology Gut+?

You can buy Gut+ probiotics directly from the manufacturer. Although made and based in the US, YourBiology ships internationally, including the UK, Australia, Ireland, Germany, and France.

What is the recommended dosage of YourBiology?

YourBiology advises taking 2 capsules daily, once in the morning and the second in the evening. You shouldn’t exceed this dosage, as you may experience gas, bloating, or other side effects.

Does taking YourBiology help you lose weight?

Supplements containing Lactobacillus and Bifidobacterium, like YourBiology, can boost weight loss as they act as an appetite suppressant. They may also prevent the absorption of some dietary fats, which means your body will extract fewer calories from the foods you eat. However, to lose weight, you’ll ultimately need to be in a caloric deficit, burning more calories than consumed.

How I Tested YourBiology Gut+

If you’re looking to purchase a dietary supplement, it’s important that you know all of the details about its quality, efficiency, price, and brand reputation before you buy. To help you make your final decision, here’s what I thought about YourBiology in 4 different areas:

Quality 9/10

Whether a dietary supplement, medication, or food product, anything that you put into your body should be high-quality to ensure that it is effective while providing minimal side effects. 

Containing only natural ingredients, YourBiology Gut+ scores top marks in this category. It uses 4 effective probiotic strains that help improve gut health, regulate digestion, and boost immunity, among other benefits, without causing too many disruptive side effects.

Effectiveness 9/10

With the Maktrek technology, YourBiology is highly effective, as it helps the capsules to pass through stomach acid safely. All of the other ingredients within the formula are also backed by scientific research and have proven to be effective in improving gut health.

Price 7/10

From what I’ve seen on the market, YourBiology probiotics are certainly at the higher end of the price scale when it comes to supplements. Although they offer plenty of incentives, like payment installments and bundle discounts, it might not be accessible to everyone on a tighter monthly budget.

Brand reputation 9/10

I’ve only heard excellent things about YourBiology from online reviews and customer quotes on their site. The website is easy to navigate and transparent – it gives you the ins and outs without being pushy or overpromising. In my opinion, that builds credibility. Plus, the 60-day money-back guarantee shows that the brand truly cares about helping its customers.

A Word From Our RD

Probiotics are friendly live bacteria that occur naturally in the body, in areas such as your gut, vagina, skin, lungs, mouth, and urinary tract. It’s important to maintain a healthy balance of good and bad bacteria to prevent illness and infection.

Taking good probiotic supplements is a great way of restoring this balance, particularly if you are looking for a quick and convenient way to improve your digestion and stop feeling sluggish. However, you can also get them by eating a range of probiotic-rich foods, such as sauerkraut, olives, Greek yogurt, and aged cheeses, to name a few.

However, these supplements aren’t suitable for everyone, especially if you are pregnant, breastfeeding, or have a weakened immune system. Probiotics can also interact with certain medications and reduce their effectiveness, so speak to a healthcare professional before trying them.


If you’re looking for a pro and prebiotic supplement that can help to balance your gut microbiome, then I’d recommend giving YourBiology Gut+ a go. 

Although the product is on the pricey side and may cause some initial side effects like bloating and cramps, the 4 probiotic strains leave your body well-equipped to fight harmful bacteria. By-passing the stomach acid is another feature I particularly liked about YourBiology, as it allows your body to soak up the essential nutrients needed.

Always consult your doctor before adding a new supplement to your daily routine.
