bio-kult FAQs

ᐅ Can I get a bio-kult discount code?

Yes, bio-kult discount codes are available, but it depends on the type of customer you are. If you’re new to bio-kult, a 15% welcome code is almost always active. It’s a consistent discount, but it applies to first orders only.

For returning customers, discount codes are less frequent. General-use codes aren’t live all the time, but promotions cycle regularly (usually every couple of months). The deals are often spend-based offers like 10% off when you spend £30 or more. They don’t usually require a code and only run for a short window. If you shop with bio-kult regularly, it’s worth timing your order to line up with these deals.

ᐅ Does bio-kult have any side effects?

bio-kult is generally considered safe, with few reported side effects. However, some of their products contain a high concentration of live bacteria, which can cause symptoms like gas, bloating, and a chance of bowel movements. Usually, these side effects wear off after a week or two as your gut adjusts to the new live cultures. Try a smaller dosage if you are worried about these side effects.
