What is the difference between BioTic 4 Billion and BioTic 20 Billion?
BioTic 4 Billion provides 4 billion CFU for everyday maintenance and those new to probiotic supplementation. BioTic 20 Billion provides five times the culture count (20 billion CFU) across 8 strains, suited to more intensive gut recovery, post-antibiotic use or those with significant digestive conditions.
Is BioTic 4 Billion suitable for IBS?
Probiotics including Lactobacillus acidophilus and Bifidobacterium have been studied for IBS symptom management with positive results. BioTic 4 Billion may help reduce bloating and normalise bowel patterns in IBS sufferers, though individual responses vary.
Can I take BioTic while taking antibiotics?
Yes — take BioTic at least 2 hours apart from your antibiotic dose to prevent the antibiotic from killing the live cultures. Continue for 4–8 weeks after completing your antibiotic course to restore microbiome diversity.
Is BioTic 4 Billion vegan?
Yes. The strains are grown on plant-based growth media and the capsule is vegetable cellulose. It is certified free from dairy and animal-derived ingredients.

This piece is a solid find. This is the kind of garment you can throw on and instantly feel put-together. I’ve styled it with trainers and boots and it works both ways. The colour is a touch different to the photos, but still very wearable.
Appreciate your honest thoughts, it really helps us improve.

Honestly one of my favourite buys recently. Feels a lot more expensive than it is. I’ve worn this piece a few times now in different situations – running errands, meeting friends, even to the office – and it works every time. The fit is true to size on me, with enough room to layer underneath without feeling bulky. After a couple of washes it’s still holding its shape and colour, which I really appreciate.
Thank you so much for taking the time to leave a review – we really appreciate it.
