How Do You Know If You Need Probiotics?

Probiotics have an important role in the maintenance of the natural environment inside the gut, which can keep the gut in a healthy state or an unhealthy state (when there is a probiotic deficiency). Some wonder if probiotics should only be used when prescribed for some conditions, or if they could simply be used daily, whether or not you are healthy.

What Are Probiotics?

Probiotics are live microorganisms, primarily bacteria and yeasts, that provide health benefits when consumed in adequate amounts. Often referred to as “good” or “friendly” bacteria, they are naturally found in certain foods, supplements, and the human body, especially in the gut. Probiotics play a key role in maintaining a healthy balance of gut microbiota, which is essential for digestion, immunity, and overall well-being.

Types of Probiotics?

The three most common types of probiotics are Lactobacillus, Bifidobacterium, and Saccharomyces boulardii. Lactobacillus is found in yoghurt and fermented foods; it helps with digestion and may improve lactose intolerance. Bifidobacterium is found in some dairy products; it supports gut health and may reduce symptoms of irritable bowel syndrome (IBS). Saccharomyces boulardii is a yeast probiotic that can help with diarrhoea and gut health.

Benefits of Probiotics?

Probiotics offer a wide range of health benefits by promoting a balanced gut microbiome. Here are some key advantages:

Improved Digestive Health

Probiotic consumption can improve digestion and nutrient absorption. This will alleviate symptoms of gastrointestinal issues like bloating, diarrhoea, constipation, and irritable bowel syndrome (IBS). Additionally, it will support recovery from antibiotic-associated diarrhoea and other disruptions to gut health.

Support the Immune System

Probiotics can strengthen the immune system by enhancing the gut’s ability to fight harmful bacteria and viruses, thereby reducing the risk and severity of infections, including colds and respiratory illnesses.

Improved Mental Health and Mood

Probiotics can improve the gut-brain axis to improve mood, mental focus, and sleep quality, and help regulate neurotransmitters like serotonin, potentially reducing symptoms of anxiety and depression.

Improved Skin Health

Probiotics may improve conditions such as acne, eczema, and rosacea by reducing inflammation and balancing skin bacteria.

Aids in Weight Management and Metabolism

Probiotics support weight control by promoting a healthy gut microbiome and improving fat metabolism. Probiotics can help regulate blood sugar levels and reduce the risk of metabolic disorders.

Improved Vaginal and Urinary Health

Probiotics can help to maintain vaginal health by balancing microbiota and preventing infections like yeast infections and bacterial vaginosis, as well as reducing the risk of urinary tract infections (UTIs).

Allergy and Inflammation Reduction

Probiotics may lower the risk of allergies and reduce inflammatory responses in conditions like eczema or asthma.

Overall Well-being

Probiotics can enhance energy levels and reduce fatigue by supporting nutrient absorption and gut health. This also helps to mitigate the side effects of medications, especially antibiotics.

Probiotic Deficiency Indicators:

If you identify one or more of these symptoms regarding your health, it can indicate that you may benefit from probiotic supplements and foods:

• Sleep disorders
• Chronic fatigue
• Unstable mood
• Bowel disorders
• Skin conditions (dermatology)
• Allergies
• Brain fog

Who May Benefit from Probiotics?

Are you healthy and wondering if it is necessary to take a probiotic? Some research suggests that daily probiotic supplementation may benefit healthy people, but more research should be done on the effect on older people. There are no dangers in taking a probiotic when you are healthy.

The gut microbiome is something that can be affected or disrupted easily through lifestyle and diet factors, but also medication. The gut microbiome may be unbalanced without having a serious disease. It is thus important to be aware of small symptoms that can indicate that the gut microbiome needs some care. Much research has been done to see if probiotics are beneficial, and most research confirms that probiotics can have a positive effect on health.

Antibiotic Courses

Antibiotics, especially when used long-term, can harm the gut microbiome by killing both harmful and beneficial bacteria. This imbalance may lead to issues like diarrhoea and vaginal thrush, as unwanted bacteria thrive in a disrupted microbiome. Taking probiotics alongside antibiotics can help restore gut balance and minimise side effects.

The NHS supports probiotic use, and doctors or pharmacists may recommend them during antibiotic treatment. Probiotics can be taken as supplements or through probiotic-rich foods like yoghurt. For best results, take probiotics daily during and after the antibiotic course, leaving a gap of 1–2 hours between doses. Dosage varies by supplement type.

Digestion Problems

An unhealthy gut microbiome, or dysbiosis, occurs when the balance of gut bacteria is disrupted due to reduced diversity, loss of beneficial bacteria, or an increase in harmful bacteria. This imbalance can contribute to digestive issues like irritable bowel syndrome (IBS), characterised by bloating, abdominal pain, and irregular bowel habits, which may improve with probiotic use.

Probiotics may also help reduce the frequency and severity of ulcerative colitis flare-ups, a chronic inflammatory bowel disease causing inflammation and ulcers in the bowel. Maintaining a healthy gut microbiome is essential, as it impacts digestion, mental health, sleep quality, and even skin conditions, though more research is needed, particularly in older populations.

Mental Health Strain

Fatigue and difficulty concentrating can sometimes be linked to poor gut health, as an unhealthy gut microbiome may affect energy levels and cognitive function. While more research is needed, studies suggest that probiotics can improve mental health, enhance focus, and even support better sleep.

An imbalance in gut bacteria can also impact mood and emotional well-being through the gut-brain connection. Probiotics may help by promoting the production of neurotransmitters that regulate mood, potentially alleviating symptoms of anxiety and depression.

Immune System

If you frequently get colds or are sensitive to allergies, probiotics are something that you can consider. A healthy gut can help your body’s natural defence system to reduce the possibility of illness and infections. The gut, as part of the immune system, is where pathogens come into contact with the body, and healthy gut bacteria can kill pathogens.

Research suggests a link between gut health and immune disorders, like certain autoimmune conditions. Probiotics may help modulate the immune system and alleviate symptoms.

What Are Sources of Probiotics?

Probiotics are found in a variety of natural and supplemented sources. The main categories include fermented dairy products, fermented non-dairy foods, soy-based products, and probiotic-enriched products. Incorporating these sources into your daily diet can support gut health and overall well-being. Always check product labels for “live and active cultures” to ensure probiotic content.

Fermented Dairy Products

Fermented dairy products such as yoghurt, cheese, and kefir contain probiotics. Yoghurt is made from milk fermented with probiotic bacteria like Lactobacillus and Bifidobacterium. Plain Greek yoghurt is a good source of probiotics to take, although other yoghurts are also an option. Kefir is a fermented milk drink containing a diverse range of probiotic strains. Certain aged cheeses like Gouda, Cheddar, and Mozzarella may contain probiotics if labelled as live-cultured.

Fermented Non-Dairy Foods

Sauerkraut is a fermented cabbage rich in probiotics, especially Lactobacillus. Kimchi, a Korean fermented vegetable dish, contains beneficial bacteria. Naturally fermented pickles (not vinegar-based) contain probiotics. Sourdough bread may contain live cultures, though levels are often lower after baking. Fermented vegetables, like carrots and beetroot, can provide probiotics.

Beverages

Kombucha is a fermented tea drink containing probiotics and antioxidants. Some commercially available juices are fortified with probiotics.

Soy-Based Products

Soy-based products such as miso, tempeh, and natto contain probiotics. Miso is a fermented soybean paste used in soups and marinades. Tempeh is a fermented soybean product with a nutty flavour. Natto consists of fermented soybeans and is particularly popular in Japan.

Probiotic Supplements

Probiotic supplements are available as capsules, tablets, or powders in health stores and pharmacies, containing specific strains for targeted benefits. Liquid probiotic supplements are often marketed for digestive or immune health.

Probiotic-Enriched Products

Some food products, including cereals, chocolates, and snacks, are fortified with probiotics for added benefits.
