What are probiotics and why should you take them?

What are Probiotics?

Basically, they’re a type of bacteria.

The human body carries nearly 100 trillion bacteria in the gut, which is more than 10 times the total number of cells in the entire body. That’s crazy, isn’t it?

Probiotics are the “good” variety of bacteria that help keep the intestines healthy and assist with nutrient absorption.

They’re the good guys!

Yoghurt contains probiotic cultures such as lactobacillus which promote healthy digestion.

Why take probiotics?

Well, the benefits of probiotics are multifaceted and growing as more research is undertaken.

But if you’re dubious about taking another vitamin capsule, here’s why a probiotic may help you feel good all year round.

How do probiotics work?

Probiotics work to help maintain balance in the intestinal microbiota. By enhancing the intestinal flora, these microorganisms have a larger effect in terms of keeping people in good health.

Recent research on the microbiome has shown that its influence extends far beyond the gut, playing a crucial role in both our digestive and immune systems.

Even more recently, studies are showing the role of the microbiome in areas including brain health, memory and even mental health.

Let's talk about a few ways Probiotics can help you in your day to day life...

Probiotics support the digestive system

The main benefit of taking a probiotic is the support it gives to the digestive system and gut by delivering healthy bacteria to the body.

People with digestive issues and sensitivities such as lactose intolerance can enjoy reduced symptoms whilst taking a probiotic supplement.

Probiotics have an almost anti-inflammatory effect on the digestive system and stimulate the immune system which promotes a healthy gut.

Immunity boost with Probiotics

The increased number of good bacteria in the gut is also beneficial for immunity. A probiotic supplement can provide immune support to help you stay healthy year-round.

Researchers are starting to discover the real importance of gut bacteria, including their influence on the immune system.

The gut accounts for 25% of the immune cells in the body while providing 50% of the body’s actual immune response.

Studies have found that probiotics can stimulate the immune system during the winter months to guard against sickness, even in the elderly!

Probiotics helped to see a decrease in respiratory conditions in humans and a better functioning immune system.

Probiotics can provide relief in sickness

On a course of antibiotics? Probiotics are especially useful here.

By delivering lots of good bacteria to the body, probiotics can reduce the negative effects of antibiotics such as diarrhoea and can also prevent thrush in females.

They’re also a useful addition to your diet when coming down with the winter lurgy, gastro, diarrhoea and any immune compromising sickness.

Bulk Nutrients Proviotic

We have our very own probiotic capsule here at Bulk Nutrients, Proviotic.

Proviotic contains a patented strain of the probiotic, Bacillus Subtilis, a spore-forming probiotic as well as a full spectrum of formulated vitamins and minerals.

Each serving contains a full dose of the probiotic and 25% of the recommended daily intake (RDI)of vitamins and minerals.

What’s special about Proviotic?

Proviotic's type of probiotic

The majority of probiotics on the market today are bacteria that are “non-spore” formers such as lactobacilli and Bifidobacteria. These probiotic strains have been widely studied for their health benefits and are a popular choice for use in dietary supplements of cold-pressed foods such as yoghurts.

Supplementing with a probiotic may help you feel good all year round.

Our Proviotic, on the other hand, contains a spore-forming bacteria called Bacillus Subtilis. This species of microorganism has been known for almost 100 years and is considered to be a normal inhabitant of the gut in humans.

Bacillus Subtilis comes from a diverse group of very hardy bacteria, characterised by their ability to form endospores to protect themselves in varying conditions such as high temperature and highly acidic environments.

These bacterias have the ability to form spores that protect the microbes from harsh conditions until they enter an environment suitable for germination, like the GI tract.

With just one serve, Proviotic Capsules offer 25% of the recommended intake of vitamins and minerals plus over 5 billion cfu per dose.
With just one serve, Proviotic Capsules offer 25% of the recommended intake of vitamins and minerals plus over 5 billion cfu per dose.

They remain viable under a wider range of conditions, don’t require refrigeration and can survive the passage through the acidic environment of the GI tract. After surviving the GI tract they can sporulate, increasing in numbers.

The hardiness of this spore-forming probiotic strain used in Proviotic makes it an effective source of healthy bacteria.

Proviotic provides added vitamins

Another difference between Proviotic and regular probiotics supplements is the added vitamins and minerals. Each serve delivers 25% of the RDI needed for general health and wellbeing. This saves you from taking a multivitamin and a probiotic capsule. So simple!
