What Are Postbiotics? How They Can Support Eye Health and More

Postbiotics are a new term that is popping up in the world of supplements and gut health. Many people are aware of probiotics, and even prebiotics, but just what is a postbiotic?

In this article, we will explain what postbiotics are, why some of them may be supportive of your eye health, and where to find postbiotics for eye health, eye fatigue, and blue light strain.

What are postbiotics?

Postbiotics are essentially a form of probiotics. Except, postbiotics are probiotics after they have been strategically “heat-killed” on purpose. Some of these postbiotics (or, dead probiotics), have been found to still deliver benefits to the gut or beyond, even though they aren’t technically living any longer.

One of the plus sides of postbiotics when it comes to formulating certain supplements is that they don’t need the same temperature control or refrigeration that live bacterial strains may require. This may be an upside to supplement manufacturers or users that don’t want to have to worry about keeping their supplements chilly.

What are the differences between postbiotics, probiotics, and prebiotics?

Probiotics: Live “good” bacteria strains. Probiotics can come from the foods you eat, especially healthy fermented foods. Or, from supplements and powders as an addition to your diet.

Prebiotics: The food that the probiotics eat in order to thrive and replicate. These are normally indigestible food components, and are eaten through your food or taken in supplements. For example, the fiber component of the food you eat is the most common prebiotic source for most people.

Postbiotics: Purposely heat-killed “dead” probiotics. This can also be thought of as the “end products” of what happens after probiotics and prebiotics have lived together. These are bioactive compounds that can change things in your body or elicit positive immune responses.

How can certain postbiotics support eye health?

When most people think about probiotics or healthy bacteria, they think about the benefits for gut health and digestion. But, the truth is that the benefits of healthy bacterial strains in your body go far beyond just intestinal comfort and regularity. 

A healthy and thriving bacterial ecosystem throughout your body is actually key to a healthy immune system, mood, weight management, and even your eye health and eye protection.

EYEMUSE is one of the first and most well-studied postbiotics when it comes to targeting eyes specifically. EYEMUSE utilizes the postbiotics of a bacterial strain called Lactobacillus paracasei KW 3110. Lactobacillus is a common bacterial strain used in the milk fermentation process to make various fermented food items. But, in this case, these postbiotics have shown promise in promoting eye health and support.

The creators of EYEMUSE have run clinical trials to see just how EYEMUSE can help with eye health and strain. What these studies have shown is that EYEMUSE may help improve eye fatigue, suppress inflammatory stress on eye cells, and reduce negative blue light effects. 

Because of these potential benefits, EYEMUSE might be a good option for a wide range of people. Whether you are a gamer and you want to be functioning at peak performance, you are a professional putting in long hours looking at screens, you are already dealing with eye conditions that make your eyes more sensitive to blue light strain or damage, or you just live in this increasingly digital world.

Do all postbiotics support eye health?

Postbiotics are an emerging class of probiotics. Because of this, we are still in the process of researching what they can and can’t do, and which strains are best suited for various applications. As more research is done on postbiotics, we will have a better picture of all the benefits they hold, and which ones can be applied to eye health.

So, at the moment, if you are interested in postbiotics for eye health specifically, EYEMUSE is a good and increasingly more well-studied choice.

Where to find postbiotics for eye health?

The creators of EYEMUSE, which is a postbiotic for eye health, work with supplement manufacturers directly to have their product used in eye health supplements.

One of the easiest to obtain is The EyeMazing Gummy eye supplement from Zen Nutrients. This supplement contains EYEMUSE as one of the ingredients, and it also uses other eye health ingredients for a well-rounded and comprehensive formula.

If you want to use postbiotics for eye health, simply order The EyeMazing Gummy eye supplement from Zen Nutrients directly, or from Amazon.
