Each different strain of probiotic is able to improve different aspects of your health better than others so it’s important to choose the right ones. Bifidobacterium infantis is one of these powerhouse strains. We’ve done all the research to get you the insider scoop on what it is, what it does and how it does it.

So what is Bifidobacterium infantis?

Bifidobacterium infantis (B. infantis) is a species of probiotic that belongs to the family ‘Bifidobacteria’ which live in your intestines and stomach. They are healthy bacteria that confer health benefits onto their host – that’s you.

Bifidobacterium is a lactic acid bacteria that produces vitamins, digests fibres, sugars and complex carbs and fights off infections from bacteria that’s not as friendly. Overall, probiotics in this family improve digestion and boost the immune system but each strain within this group have their own strengths, making up a powerhouse of beneficial bacteria together.

Specifically, B. infantis is the best strain at breaking down the complex sugars and lactic acid in breast milk – which is why it’s named with babies in mind. Despite this, though, it also benefits children and adults so it shouldn’t be overlooked.

B. infantis can be consumed in many ways, you can find it in fermented food and drinks or you can consume it as a daily supplement in powder, tablet or capsule form – which is usually the most convenient way.

Is Bifidobacterium infantis right for me?

It all depends on what you’re wanting B. infantis to help you with. Generally though, it’s a safe and natural alternative to many other medicines. As you’ve already got probiotics in your gut, introducing a few more isn’t usually going to cause a negative reaction. Your body is already somewhat used to them. If you’re unsure though, it’s always best to have a chat to your doctor beforehand.

And be sure to steer clear of probiotics all together if you fall into any of the below categories:

• Individuals with a compromised immune system or taking immunosuppressive medication
• Individuals who are critically ill
• Individuals who’ve undergone surgery recently

Benefits of Bifidobacterium infantis

Now that you know what B. infantis is and where it comes from. Next we’re going to find out what it can do and how it can benefit our health in everyday life. Keep reading till the end because we’re also going to explore possible side effects and a few of the best probiotics on the market containing our superstar strain. This will give you a benchmark when purchasing your own probiotics.

1. Utilises sugars in breast milk

This is an important one for the mums and bubs out there. Babies are given their first full dose of bacteria as they go through the birth canal but their microbial journey doesn’t stop there.

As mentioned above, B. infantis is found in abundance in breast milk, so infants who are breastfed have the highest concentrations of it. In fact, it’s estimated that infants can ingest from 10 to 100 million bacterial cells from breast milk each day with all different kinds of strains included.

If you’re breastfeeding, you probably already know how beneficial it is for your bub. B. infantis is the probiotic responsible for breaking down the sugars in your milk and allowing your baby to fully utilize them. Without this probiotic, the complex sugars in your breast milk are actually indigestible to humans – so B. infantis is something you’re going to want to have a lot of!

This breakdown of the sugars in your breast milk will also mean B. infantis is producing acetic acid that keep fungus and yeast under control whilst providing a valuable source of energy for your baby’s growing body.

2. Produces folate and sialic acid for healthy development in babies

Most expecting mums have heard about folate. It’s vitamin B9 and is essential for healthy growth and development of your baby. It also assists with the production of red blood cells that carry oxygen in the blood and remove carbon dioxide from the body.

B. infantis actually produces folate along with sialic acid which is another essential nutrient for the healthy brain development of your baby. This sialic acid is produced when B. infantis breaks down the complex sugars in your breast milk.

Another cool thing that B. infantis does for your baby is signalling their gut cells to fill in the gaps in their intestinal walls with proteins. Filling in these gaps means that toxins and unfriendly bacteria can’t slip through the wall and into their bloodstream to wreak all kinds of havoc.

But it doesn’t stop there! Because B. infantis is so abundant in breast milk, breastfed babies will have a gut that is dominated by this strain of probiotic, which means the bad bacteria doesn’t have any space to thrive and will be flushed out of their tiny body. Ultimately, bub is going to have a bulletproof gut that promotes healthy immune and development which will become the basis of their overall health throughout their life.

3. Anti-inflammatory superpowers

Like most probiotic strains, their anti-inflammatory properties are simply amazing. Whilst controlling around 70% of your immune response they can help to modulate inflammation in particular.

Inflammation is a crucial part of healing but sometimes the body can go a little overboard and damage healthy tissue. B. infantis is able to reduce this risk which has awesome benefits in the long-run. It will help ease the symptoms of a huge range of conditions like IBS (explored in the next paragraph), inflammatory bowel disease, arthritis, ulcerative colitis, chronic fatigue and more. By reducing excessive inflammation in the body, this means that you’re also less likely to develop chronic diseases later in life like diabetes and dementia.

4. Relieves IBS symptoms

Around one in five Australians will experience Irritable Bowel Syndrome (IBS) at some point in their lives and women are affected 2-3 times more than men. Whilst it affects so many people, the exact causes and a way to cure it completely has not been found yet due to this condition’s complexity. IBS comes with many uncomfortable and inconvenient symptoms like abdominal pain, changes to stool frequency, bloating and more that are triggered by different factors for every person. This could be stress, food allergies, diets with high amounts of sugar and spicy food, some medication – the list goes on.

Around 5 studies were analysed that closely monitored the effect of B. infantis and other probiotic strains on the symptoms of IBS; mainly abdominal pain, bloating/distention and bowel habits. It was observed that B. infantis on its own didn’t have much of an effect at all, but when combined with other probiotics it created a dramatic improvement for the symptoms mentioned above. The singular effects of this strain need to be studied more but if you’re taking probiotics for IBS, these studies show that B. infantis is a must-have.

There may be some mild side effects when first taking probiotics, however, as your body may not be used to such a large dose of friendly bacteria. Here’s what you might experience:

Possible side effects:

• Mild digestive issues – As with most new supplements, some small teething issues may occur. Gas and bloating along with mild digestive discomfort might be experienced whilst your body is getting used to such a bit hit of probiotics each day. This is nothing to worry about and will disappear after about two weeks, but let your doctor know if it doesn’t or if it’s anything more than some mild discomfort.
• Allergic reactions – Double check the label when purchasing a probiotic product because it could contain a common allergen or two that might disagree with you. Soy, dairy and egg can sometimes be used in these products as you saw in our probiotic product section above.
• Risk of infection – As mentioned at the beginning of this article, anyone with a compromised immune system, taking immunosuppressant medication or those who have undergone surgery recently should chat to a doctor beforehand to make sure it’s okay to consume probiotics.
