Probiotics - Should you take them and when?
Updated: Sep 18, 2019
By Sue Wilby - Naturopath & Nutritionist
The human gut is a natural environment for a large and dynamic bacterial community (microflora), both beneficial and harmful. All individuals have between 500-1000 different species of bacteria residing in the digestive system, starting in the oral cavity and ending in the colon which has the densest population.
Alterations in the balance of good vs bad intestinal flora (dysbiosis) are caused by the use of antibiotics, acute diarrhoeal illnesses, psychological and physical stress, altered digestive tract peristalsis and dietary changes
The major role of our microflora includes:
The production of short-chain fatty acids, predominantly butyrate, which provides energy to the gut cells (colonocytes).
The production of vitamins including vitamin K, folate and other B vitamins;
The absorption of calcium, magnesium, and iron;
The enhancement of digestive tract motility, reducing the risk of constipation
The breakdown of non-digestible dietary residues
They play a key role in an individual’s immune system and provide a protective function between you and alien microbes.
It is also suggested that (bad) gut microflora may play a role in some disorders including inflammatory bowel disease, colon cancer, and autoimmune diseases.
Why take probiotics?
Probiotics are defined as ‘living microorganisms, which when administered in adequate amounts deliver health benefits on the host’
This occurs in the following ways:
the manipulation of intestinal microbial communities;
the suppression of pathogens
stimulation of epithelial cell proliferation
improving the function of the immune system
strengthening the intestinal barrier of the digestive tract
Therefore, probiotics maintain, restore or improve the microflora in the gut to a healthier state.
When should probiotics be considered?
When taking a course of antibiotics which can disrupt the balance of the microflora
To minimise the risk of antibiotic-associated diarrhoea and thrush
During the 3rd trimester of pregnancy
During gestation (pregnancy) if either partner has a history of eczema or asthma
Irritable Bowel Disease (Crohn’s Disease, Ulcerative Colitis)
Irritable Bowel Syndrome
Urinary tract infections
What sets them apart?
Probiotics differ according to the genus (e.g. Bifidobacterium, Lactobacilli), species (e.g. L. acidophilus, L. rhamnosus) and strain (e.g. Shirota) and while all probiotics are therapeutic some species are more effective than others in certain conditions. Therefore it will always be beneficial to first speak to your health care professional to help you identify the most appropriate probiotic strains for you.
