Advanced Probiotics is a multi-strain probiotic supplement designed to support gut microbiome diversity and digestive comfort. Probiotics are live bacteria that, when taken consistently, may help restore and maintain a balanced gut flora — particularly relevant after antibiotic courses, periods of poor diet, travel, or persistent digestive irregularity.
Multi-strain formulas are generally preferred over single-strain products because different bacterial species colonise different regions of the gut and may contribute distinct benefits. Common strains in this class include Lactobacillus and Bifidobacterium species, which are studied for their role in supporting bowel regularity, reducing bloating, and contributing to gut-associated immune function. The gut houses a large proportion of the body's immune tissue, so a well-supported microbiome has broader relevance beyond digestion alone.
This supplement suits anyone experiencing mild digestive discomfort, those recovering from antibiotic treatment, or individuals whose diet lacks sufficient fermented foods and dietary fibre to sustain healthy bacterial diversity. It fits neatly into a daily morning routine and is taken as a single capsule.
As with any probiotic, consistency matters more than dose timing — daily use over several weeks is typically required before noticeable changes in digestive comfort emerge. Those with compromised immune systems or serious gastrointestinal conditions should consult a clinician before starting any probiotic supplement.
Multi-strain probiotic blend

Take one capsule daily, ideally at the same time each day to maintain consistency. Follow the dosage guidance on the packaging. Probiotics can generally be taken with or without food, though some strains fare better with a meal — check the label for specific guidance.
Most people need at least two to four weeks of consistent daily use before noticing meaningful changes in digestive comfort. Gut microbiome shifts are gradual — a single dose will not produce a noticeable effect.
Yes, but timing matters. It is generally advised to take probiotics a few hours apart from an antibiotic dose, as antibiotics can kill the live bacteria before they reach the gut. Continue for at least the duration of the antibiotic course and for a period afterwards.
People with compromised immune systems, those who are critically ill, or anyone with a central venous catheter should consult a doctor before taking any live probiotic. If you have an inflammatory bowel condition such as Crohn's disease or ulcerative colitis, speak to your gastroenterologist first.
Storage requirements vary by formulation — some multi-strain probiotics are shelf-stable, while others require refrigeration to maintain live bacterial counts. Check the packaging for the specific storage guidance for this product.
Probiotics are generally compatible with most supplements. The main consideration is separation from antibiotics or antifungals, which can reduce the viability of live strains. If you are taking any prescription medication, check with your pharmacist or GP.

Had persistent bloating for months after a bout of food poisoning abroad. A GP friend suggested I try a multi-strain probiotic rather than a single-strain one, so I picked these up. Three weeks in and the difference is noticeable — less bloating, much more regular. I take one every morning with breakfast. Won't be without these now.

Finished a 10-day antibiotic course in January and my gut was a mess afterwards. Started taking these daily and within a few weeks things settled down considerably. Simple capsule, no weird taste or smell. Does what you'd want it to do.

I've been taking these for about six weeks and genuinely do feel like my digestion has evened out — less of the uncomfortable afternoon bloat I used to get. My only gripe is that the bottle only contains 30 capsules, so you're reordering every single month with no buffer if delivery is delayed. A 60-cap option at a slightly better per-unit price would make this an easy five stars.

Bought after a friend's recommendation — she'd used it after travelling and swore by it. I was sceptical but I've noticed my digestion is noticeably more settled since I started. About five weeks of daily use before I really saw the difference, so stick with it.

I already take magnesium and vitamin D in the morning, so slipping this in alongside was effortless. My diet isn't great for fermented foods, so I figured a decent probiotic made sense. No dramatic overnight changes, but consistently over a couple of months I've had far fewer days where my stomach feels off. At £17.99 it's reasonable for what you get.

Straightforward, no fuss. Been taking one capsule each morning for a while now and my gut feels more settled than it has in years. Good value.
