Formulated without refrigeration requirements and with an acid-resistant capsule for maximum delivery to the gut.

Frequently Asked Questions

What is the difference between BioTic 4 Billion and BioTic 20 Billion?

BioTic 20 Billion offers five times the culture count (20 billion vs 4 billion CFU) and the same 8-strain formulation. It is recommended for those seeking higher-strength support, following antibiotic use, or managing more significant digestive conditions.

Should I take probiotics after antibiotics?

Yes — antibiotics can deplete beneficial gut bacteria. We recommend starting BioTic 20 Billion at least 2 hours after each antibiotic dose, and continuing for 4–8 weeks after completing your antibiotic course.

Can I take BioTic 20 Billion every day long-term?

Yes. Daily probiotic use is safe and beneficial for most people. Consistent use supports a balanced and diverse gut microbiome, which is associated with better digestive, immune and even mental health outcomes.

Is BioTic 20 Billion suitable during pregnancy?

Probiotics are generally considered safe during pregnancy, but we recommend consulting your midwife or GP before starting any new supplement during pregnancy or breastfeeding.

So glad I ordered this

Absolutely obsessed with this piece. Feels a lot more expensive than it is.

Perfect for everyday wear

Honestly one of my favourite buys recently. This is the kind of piece you can throw on and instantly feel put-together. I’ve styled it with trainers and boots and it works both ways. This garment feels very easy to dress up or down. I’ve worn it with simple trainers in the day and swapped to heeled boots and jewellery in the evening and it worked both times. It also layers nicely under coats without bunching up, which is ideal for UK weather. Overall it feels like something I’ll keep in my wardrobe for a long time.

This is lovely feedback, thank you for sharing your experience.

Really good, just a small tweak

Really like this piece overall. This garment has become one of my most reached-for pieces. The fit feels flattering without being too tight and the fabric is comfortable enough to wear all day. The colour is a touch different to the photos, but still very wearable.

So happy to hear you’re enjoying your order, thanks for letting us know!

It’s fine but not perfect

This piece is okay but not amazing. The fit isn’t quite right on my body type, so I don’t reach for it as often as I thought I would. If you like the style it’s worth a try, but I wouldn’t call it a must-have.

Lovely piece overall

Pleasantly surprised by this piece. 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. Length is a bit longer/shorter than I expected, but nothing major.
