What Are Probiotics And How Do They Work?

The word “probiotic” in itself affirms life and health. In Greek, “pro” signifies promotion of and “biotic” means life.

According to the World Health Organization, a probiotic is a living microorganism that confers the health benefit on the host when administered in adequate amounts.

Whar Are Probiotics?

When we think of bacterias, we immediate relate to them with disease and illness. Not all bacterias are bad, probiotics are good, friendly and helpful bacteria found in our digestive system.

Probiotics are live bacteria which are healthy and naturally found in our body.

Probiotics prevent harmful bacterias to settle in the gut as they compete with bad and harmful organisms for food and space.

They line up the digestive tract in the body, help absorb nutrients from the food you eat and also fight infections.

Would you believe? Your gut holds 10 times more probiotics than cells in your body.

These friendly and good bacteria have been in our system since the time we were born. We were first exposed to probiotics while we were in the birth canal about to be born.

Unfortunately, in today’s world, we do not get probiotics from the food we consume. This could be attributed to factors such as dangerous agricultural practices, refrigeration, soaking or washing food in chlorinated water, use of antibiotics to name a few.

Probiotics can be found in some naturally fermented foods. After their newfound fame, they can be found in almost everything from chocolates to protein bars to supplements to yogurts.

How Do They Work?

There are trillions of good and bad bacteria in the digestive tract. These bacteria make up for the gut microbiota which is considered to be the key to good health.

Good bacteria share a symbiotic relation with the body. The body provides energy to the good bacteria from the food we consume and in return, it provides many health benefits to the body.

According to experts, the good and optimal balance of gut flora should be in the ratio of 85% good & beneficial bacteria to about 15% of other microbes.

Eating certain foods which offer probiotics or supplements help replace good bacteria and fill the imbalance.

An imbalance of gut microbes may possibly have links to diseases of the intestinal tract, such as ulcerative colitis, irritable bowel syndrome, celiac disease, Crohn’s disease. It may be also linked to more systemic diseases such as obesity, diabetes and more.

In cases where the body looses good bacteria for reasons such as diarrhea or antibiotics, there would be an imbalance of ratio and the condition is called dysbiosis. Eating certain foods which offer probiotics or supplements help replace good bacteria and fill the imbalance.

Digestive tract or gastrointestinal tract are of prime importance to our health because 80% of your immune system resides here.

What you need to keep in mind is that there are different probiotics strains and they provide different health benefits. Some strains provide immunity benefits whereas another would provide you with better digestion and some might help lose weight and balance hormones.

Select the right strains of probiotics which meet your specific need to gain maximum benefits.

Look for reputable brands: Companies who have been around for. a while and known to you would be a better choice rather a maker who is unknown.

Read The Label: Look for information about the species, genus, strain, CFU’s (colony forming units) to begin with

CFU’s: This is the probiotics measurement and should be prominently displayed on the packing and label. Higher the CFU the better and ideally you should look from 15 billion to 100 billion.

Strain Diversity: Do not restrict yourselves to a single or two strains, look for the probiotic which provides at least 10 different strains and no more than 30. Not all the strains will reach your gut because many will perish due to your body’s acid and bile.

Shelf Life and Survivability: Look for a clear statement on the packaging which should say “Potency guaranteed until time of expiration.” This will ensure that you are getting guaranteed CFU’s as claimed.

Date of Manufacture: Probiotics are live supplements, fresher the better.

Live Cultures: Try and buy probiotics which say “Live and active cultures” and avoid which say “Made with active cultures”.
