Best Probiotic Supplements UK

The bacteria found in our gut is vital to our health. Everyone has their own unique microbiome, which is a mix of about 400 different types of bacteria. They inhabit the entire lining of your digestive system and affect the well-being of your whole body. 

Probiotics are a great way to top up your gut with good bacteria and support the health of your gut.

What is a probiotic

Probiotics are supplements that contain live bacteria, and they are designed to join the other good bacteria in your body. Most probiotic supplements contain live bacteria and yeasts that have been cultivated in fermented foods.

Having the correct balance between good bacteria and harmful bacteria is essential to your health and may reduce the risk factors for some severe conditions. The idea behind these supplements is that they add to you existing bacteria and ensures that you don’t get a build-up of too much bad bacteria.

For years probiotics have been a source of debate. For them to work, the live bacteria they contain must pass through your stomach acid and arrive in your gut unharmed. While it’s not clear how this happens, but the latest research shows that probiotics are effective and some bacteria do survive for long enough to colonise your gut. Unfortunately, it’s likely that if you stop taking them, they may then be flushed out of your system. Some supplements come with enteric coatings to help the bacteria survive the acidic environment of your stomach.

Probiotic vs Prebiotic

Prebiotics are types of indigestible fibre that gut bacteria can feed on. As a result, they support the health and growth of your good bacteria. Probiotics are supplements that contain live bacteria. Some probiotic supplements also contain prebiotics to help them flourish in your gut.

Why do people use probiotics?

Probiotics are often used to balance out the bad bacteria in the gut. Too much of this bacteria can cause stomach upset diarrhoea and numerous other unpleasant symptoms. 

There is also growing evidence that there is a secure link between gut health and your brain. Changes in our gut bacteria may even affect our mood and emotions. As a result, probiotics are often taken to give a boost to general health or to try and reduce feelings of being rundown, fatigued or depressed.

These useful supplements are also taken to boost the immune system, and they may likely support the treatment of conditions including irritable bowel syndrome, diarrhoea and ulcerative colitis.

What to look for when choosing a probiotic

There are hundreds of different bacteria that could be included in probiotics. The best way to find one that works for you is to find a probiotic complex that consists of a wide variety of bacteria. This means it will more likely have a positive effect on your gut and meet your needs.

When you buy your probiotic look for companies with good reputations who have samples of their products tested by third-party labs. Also, look out for evidence that the bacteria formulation is based on up to date research. Another great way to ensure you’re getting a top-quality product is to look for awards and certifications like ‘Good Manufacturing Practices’ certifications or verification that they meet organic standards.

Are expensive probiotics worth it?

Probiotics don’t work miracles, as with any supplements how effective they depend on your body composition and health as well as what they contain. Don’t spend a lot of money on any supplement unless you’re sure of its quality and you’ve seen several genuine customer reviews verifying its potency and safety. Several expensive probiotics are well-made and are worth every penny, but there are also cheaper options that also provide great value. If you’re looking for a great probiotic on a budget, check out TerraNova’a Probiotic Complex.

What is the best time to take probiotics?

The best time to take a probiotic depends on its type and what capsule it’s contained in. If it has an enteric coating, you can take it at any time. If not, try taking it with your meal, this will allow the bacteria to enter your stomach at the time when it’s least acidic.
