How Does Gut Microbiome Affect the Quality of Sleep?

The microorganisms release several crucial chemicals that govern sleep quality. The lists include cortisol, tryptophan, GABA, serotonin, dopamine, and melatonin.

So, if your body has low levels of these hormone-producing bacteria, then the level of melatonin and serotonin will also plummet. Thus, you will find it difficult to fall asleep and might also wake up at the slightest noise.

However, the gut microbes signal certain markers, thus increasing the level of specific sleep-inducing proteins. For instance, the level of two cytokines, IL-1 beta and IL-6, increases in response to microbes when your body needs rest.

Similarly, in case of an imbalance of microbes, you may wake up earlier than your routine as the microbes fail to perform due to their low numbers.

Buying Guide: Important Things to Consider Before Buying Probiotics

When looking for the best probiotic for sleep in Australia, consider your condition and current digestive issues. In general, using probiotics is safe, but keep in mind that companies earned their reputation the hard way.

To choose the best from the lot, do not opt for the first familiar name you come across. Instead, inspect the label on the bottle and look for these essentials:

  • Strain Diversity

Favor the brands offering clinically tested strains of probiotics. So, check the type of strains, the total number of strains, and the CFU count. As a rule of thumb, look for products comprising at least ten billion CFUs.

  • Regulated Factory Conditions

No matter how great the ingredients are, if the company does not follow strict standards during the making process, you cannot expect efficacy. Therefore, it is vital to buy from brands that follow FDA rules and also fair customer policies.

Furthermore, trustworthy and reliable companies send their products to third-party testing services to ensure the products' efficacy, potency, and purity. Hence, look for such verification as evidence of quality.

  • Inclusion of Prebiotics

The presence of prebiotics supports the growth of probiotics in your body. Therefore, most of the probiotics available in Australia contain both probiotics and prebiotics.
