Best Probiotic for Immune Boost

A sluggish immune system can be a major factor in your quality of life. We all know how much an immune boost would mean - from kids who seem to pick up every germ from school, to adults who worry about missing another day of work because of a sickness, and geriatric patients who face tremendous health risks from common illnesses like the flu. What can you do to improve your immune health?

Are there supplement choices you can make? What is the best probiotic for immune boost? Today we’ll answer these questions to help you get the upper hand against frustrating and sometimes dangerous threats to your health.


The Reason Your Gut is Key to Immunity

The gut is the foundation of the digestive tract - that we all know. But there’s another critical function that the gut has: it is the center of your immune system. That’s why we say that one of the best ways to get an immune boost is to look for a probiotic that optimizes gut health. When your digestion is ‘out of whack’ you know that constipation, diarrhea, and discomfort are expected side effects. In addition, changes to your immune system may also occur. While you probably don’t associate a lower immune system with your gut health, they can be strongly connected. This goes for babies and kids as well as adults, which is why we emphasize the importance of gut health from as early as in the womb, through childhood, and beyond.


How Probiotics Affect the Gut

Once you know that probiotics are important for the gut, and in turn important for the strength of your immune system, you likely want to know how exactly these probiotics work. The best probiotic for immune boost works by taking up space in your gut. Why does this matter? Because when these healthy bacteria take over much of the gut real estate, it not only has positive effects but also prevents bad bacteria from having room to colonize. This is because your digestive tract has limited space for bacteria to thrive. That space will be filled either with good bacteria or harmful ones. Probiotics give you the ability to control the balance of your gut microbiota which can optimize your health.


One of the Best Single Probiotics for an Immune Boost: Megadophilus

Natren’s Megadophilus is one of our strongest recommendations for an immunity-boosting supplement. The good bacteria in Megadophilus reside in your small intestines where most of your digestive process takes place. Lactobacillus acidophilus is the primary component of Megadophilus. It is a high-quality probiotic that provides substantially more benefits and quality than the vast majority of available probiotics that promise much more than they can deliver on. Natren has earned its reputation as a leader in probiotics because our founder, Natasha Trenev, set the standard for probiotics when she introduced Megadophilus in 1983. While many other companies have attempted to compete with Natren’s Megadophilus, its potency guarantee and excellence are unmatched.


Best Combo Probiotic for an Immune Boost: Healthy Trinity

Healthy Trinity is one of the easiest probiotics to take because we’ve done the work for you. At Natren, Healthy Trinity was developed by combining 3 of the most important probiotic supplements we offer and turning them into an easy-to-take 3-in-1 regimen. When you take Healthy Trinity, you are covering all the most important bases for choosing the best probiotic for immunity.


These 3 most beneficial probiotic bacteria are also found in our Healthy Start System. Each box contains 3 different bottles - one of each of the probiotic bacteria. These are the 3 components of our recommendation for the best probiotic for an immune boost.


All three probiotic bacteria can be found in each Healthy Trinity capsule. These bacteria are kept alive in an oil matrix delivery system, which has been Natren's unique Trade Secret for over 30 years. No one in the world has been able to copy it.  Thus, whether you chose to buy our Healthy Start System or our Healthy Trinity capsules, you cannot go wrong.  Whichever you choose, you will see results you have never seen before.


  1. Megadophilus is the first step in Natren’s 3-step system. The good bacteria delivered through this supplement focuses on the small intestines. This is a primary area for immunity because the majority of our digestion takes place in the small intestines.
  2. Bifido Factor is the second step in our 3-step system. Bifido Factor supports your large intestines with Bifidobacterium bifidum, and focuses on the large intestine. The large intestine is critical to gut health because it plays a pivotal role in removing waste material from your body.
  3. Digesta-Lac which is the final step in our 3-step system, gives support through the whole digestive process. It contains healthy bacteria that actually travels through the digestive system, providing support the entire way.


We discussed the connection between the gut and your immune system, and this link is essential to understanding how beneficial Healthy Trinity is. This 3 in 1 probiotic supports a slightly acidic environment that is needed for optimal intestinal function. It also supports the digestion of dairy, carbohydrates, and proteins. This is important because many people understand the need to ‘eat right’ to support their immune systems, but did you ever think about the need to digest your food correctly? Even if you’re eating the most ideal diet for an immune boost, your body cannot fully take advantage of these nutrients if you are not digesting them as well as possible. This is where Healthy Trinity lends a hand - to optimize your digestion and encourage those proteins, carbs, and dairy to be well available to the body.


Quality Probiotics Matter for an Immune Boost

The decision to supplement your wellness routine with probiotics is a strong step in optimizing your health. However, the next - and critical - step is to decide what probiotic company you’re are going to trust with your health and that of your family. The probiotic industry is teeming with companies who are substantially more interested in selling a product than the true science behind your health. Natren is different.


Natren was founded more than 35 years ago by Natasha Trenev, who has dedicated her life to researching, producing, and supplying the highest quality of probiotics. How is that commitment reflected in Natren probiotics? First, our probiotics are 100% potency guaranteed. That’s something that most companies cannot promise you. Our supplements are backed by 30 years of rigorous research and technology from leading scientists who are committed to discovering and creating the best products for you and your family. Not only that, but we are backed by some of the most stringent standards in excellence including a prestigious certification that our facilities received known as the International Good Manufacturing Practice (cGMP) Certification by Australia's Therapeutic Goods Administration (TGA). All these factors and more combine to make Natren the best choice for true quality probiotics.
