The Best Probiotics Supplement

A balanced gut microbiome is not just crucial for digestion and absorbing nutrients. It’s also a core part of our immune defences, controls our mental health in ways we’re only just starting to understand, and influences a vast range of functions from controlling our weight to getting a good night’s sleep.

Our in-house nutritionist Ariel Kaur Maan here at Vitamin Guide explains how probiotics help to keep us healthy, what to look for when choosing probiotics, and reviews the top 5 probiotics supplements on the market.

Why take probiotics?

Modern diets, stress, antibiotics and tummy bugs can deplete beneficial bacteria in the gut, making it harder to get enough probiotics naturally. While many probiotics are found in fermented foods like live yoghurt, sauerkraut or kefir, few of us eat enough to maintain a balanced gut microbiome. Supplements provide a convenient and reliable way to replenish and maintain healthy levels of probiotics, supporting digestive health, immunity, and overall wellbeing.

Top benefits of probiotics

Support digestive health

Probiotics help maintain a healthy balance of gut bacteria, aiding digestion and reducing symptoms like bloating, gas, and constipation.

Boost immune function

By enhancing the production of antibodies and promoting a balanced immune response, probiotics can help protect against infections.

Improve mental health

Certain strains of probiotics have been shown to reduce symptoms of anxiety, depression, and stress by influencing the gut-brain axis.

Support weight management

Some probiotics help regulate appetite, reduce fat absorption, and improve metabolic health, aiding in weight management.

Promote heart health

Probiotics can help lower LDL cholesterol and blood pressure, contributing to overall cardiovascular health.

Reduce antibiotic-associated diarrhoea

Probiotics restore the natural balance of gut bacteria disrupted by antibiotics, reducing the risk of diarrhoea.

Enhance skin health

Probiotics can help reduce acne, eczema, and other skin conditions by promoting a balanced skin microbiome and reducing inflammation.

Reduce symptoms of IBS

Certain probiotic strains can alleviate abdominal pain, bloating, and irregular bowel movements associated with IBS.

All probiotics supplements are NOT created equal

Before you run off to the local chemist for some probiotics, there are some key things you need to know. Make the right choice so you don’t waste your money.

The Ultimate Probiotics Checklist

Choose

Gastro-resistant capsules

Choose a supplement with enteric-coated or gastro-resistant capsules to protect bacteria from stomach acid, ensuring they reach the intestines alive.

A high CFU count over 30 billion

A supplement with at least 30 billion CFUs (colony-forming units) per serving will ensure sufficient numbers of live bacteria to colonise the gut effectively.

At least 10 strains of bacteria

Look for a supplement with at least 10-12 different strains to promote a diverse microbiome. Key strains include Lactobacillus, Bifidobacterium and Saccharomyces boulardii for yeast balance.

Avoid

Probiotics that need to be refrigerated

If a probiotic supplement needs to be refrigerated to stay alive, a short time at the wrong temperature could mean you’re taking a useless product of dead bacteria. Failures of temperature control happen all too often.

Single strain formulas

Avoid probiotics with only one or two strains unless recommended by a health practitioner, as they cannot provide broad-spectrum benefits and could unbalance your microbiome.

Supplements targeting a single health benefit

There are numerous probiotic products for gas and bloating, weight loss, mood, skincare and so on. Unbalancing your gut microbiome for one narrow purpose might do more harm than good - choose a broad variety instead.
