Even though humans spend a third of their lives sleeping, not many values its importance. A good night’s sleep is the key ingredient for tip-top physical, mental, and emotional well-being. 

According to a recent study, the duration and quality of sleep play an essential role in one’s physical and cognitive performance, meaning that sleep affects how individuals approach their work and social interactions. 

Recent research also established that probiotics affect sleep quality positively — the microbes in probiotics reduce anxiety and stress as they help one’s mind and body relax. 

Nevertheless, not all probiotics in the market are of excellent quality; therefore, you shouldn’t just purchase the first product you encounter — reputable firms take their time producing high-quality products for a specific market. Manufacturers don’t produce one-size-fits-all probiotics; thus, what’s available online might not suit your needs. 

This article goes over the top probiotic brands available in the Australian market. The products listed in this piece were analysed based on their interaction with users’ immune systems, efficacy, and purity.

How Gut Microflora Affects Sleep Quality 

Gut microflora release essential chemicals like melatonin, dopamine, serotonin, GABA, tryptophan, and cortisol that regulate sleep. 

If a person’s body has low hormone-producing microbes, their melatonin and serotonin levels will be lower. This makes falling asleep quickly difficult, and one wakes up easily at the slightest disturbance. 

Gut bacteria signal specific markers causing an increase in sleep-inducing proteins like IL-1beta and IL-6.  If there’s a microbe imbalance in your gut, you may wake up earlier than usual as the microflora won’t perform owing to their low numbers. 

Essential Things to Consider Before Purchasing Probiotics

When searching for the best probiotics available in the Australian market, you should factor in your current digestive issues and pre-existing conditions.

While using probiotics is generally considered to be safe, there are unscrupulous companies that manufacture their products using dubious means. 

To ensure you select the best product, don’t just settle for the most familiar brand; read through a products description and keep an eye out for the following: 

1. Presence of Prebiotics

Prebiotics support the multiplication of beneficial bacteria in an individual’s body; the product you’re purchasing should have both probiotics and prebiotics. 

2. Factory Conditions

Regardless of the ingredients’ quality, you can’t expect efficacy if a manufacturer doesn’t follow strict manufacturing practices. Therefore, purchasing probiotics from brands with fair customer policies and following FDA regulations is essential. 

Additionally, reliable manufacturers have third parties test their products to ensure their purity, potency, and efficacy. Therefore, you should use such verification as evidence of quality manufacturing practices. 

Strain Diversity

Go for brands with clinically proven probiotic strains — look at the strain types, CFU count, and the total number of strains. The best probiotics have a minimum of ten billion CFU strains.

Bottom Line

Probiotics are beneficial bacterial cultures that enhance gut health and promote overall health. Maintaining gut health simultaneously affects many vital body functions, including the immune system, sleep, and mental well-being. 

Probiotics enhance immunity, thus giving you energy and setting you on a healthy lifestyle that promotes your mental well-being and helps you develop a healthy sleeping pattern.   

The article above has singled out 13 of the best probiotic brands available on the Australian market to help you find one that best suits your needs. 

Frequently Asked Questions 

Which is the best probiotic for eliminating belly fat?

Lactobacillus Gasseri is the best probiotic for removing belly fat. Nevertheless, other Bifidobacterium and lactobacillus strains help eliminate belly fat and reduce weight. 

Which is better; prebiotics or probiotics?

Overall, prebiotics is stronger than probiotics as most probiotics usually can’t withstand the gut’s high acidity levels. Prebiotics encourage the growth of pre-existing beneficial bacteria in your stomach and don’t get destroyed during digestion. 

Should I take probiotics daily?

While this rule has several exceptions, taking probiotics daily is usually recommended. It’s essential to know that probiotics are supplements and medicine. 

Are probiotics safe for everyone?

Even though probiotics are generally considered safe, a 2017 study established that adults or children with chronic conditions or compromised immunity should refrain from using them. 

This is because some individuals with such conditions have experienced fungal and bacterial infections from consuming probiotics. 

What’s the best time to take probiotic supplements?

According to research, the best time to take probiotics is early in the morning, before breakfast or when one is going to bed since they’re most efficient when taken on an empty stomach. 

What happens to a person’s body when they start taking probiotics?

Once you start taking probiotics, beneficial bacteria are introduced to your stomach, and this leads to healthy digestion and reduces gas and bloating, which ultimately results in reduced abdominal discomfort. 

Can I gain weight while on probiotics?

Yes. Specific probiotic strains, such as Lactobacillus Acidophilus, encourage obesity as they alter stomach bacteria to enhance cellular growth.

Should I store probiotic supplements in a refrigerator?

No, you don’t have to store your supplements in a refrigerator as they’re shelf-stable, and room temperature doesn’t interfere with their efficacy. You can keep them on your nightstand, office table, or bag. 

Can I take a break from probiotics?

If you have any prolonged side effects from using probiotics, like gas and bloating, you should take a break from the supplements and ascertain you’re taking the correct strain and dosage.

How long will it take before probiotics show results?

The time it takes for probiotic supplements to take effect varies depending on the individual, as we all have different metabolic systems. Consequently, some people start noticing positive results earlier than others.

On average, most people tend to see results of probiotic use within two two eight weeks. Others start seeing results as soon as seven days. 

What’s a microbiome?

A microbiome refers to a collection of microorganisms such as viruses. Fungi, archaea, protists, and bacteria reside in a person’s skin and body. The microbiome performs various essential functions, such as enhancing gut health and immunity.
