Tumble contains live cultures, so it could be considered a probiotic. It also includes fibres such as inulin and fructooligosaccharides (FOS), which are often referred to as prebiotics. However, we refrain from using this term, we describe Tumble as a food supplement, in line with current UK guidance on how these products are presented.

Tumble is for those who want to support everyday metabolism¹ and build a consistent, simple routine. From maintaining energy² and immune function³ to supporting normal psychological function⁴ and skin health⁵, it brings together multiple elements in one place - reducing the amount of supplements you need to take, all interactions and absorbtions are accounted for within our formula.

It also includes nutrients that contribute to the protection of cells from oxidative stress⁶, as part of a more complete approach to supplementation and general wellness.

Take two capsules daily.
For best results, take them at least 20 minutes before or after drinking hot liquids, as high temperature liquids can affect live cultures.

Food: Ideally taken with food, but it’s not essential. You’ll still benefit if taken on an empty stomach as our formula accounts for all circumstances. Consistency matters far more than timing — it’s better to take Tumble every day than to wait for the “perfect” moment.

Timing: Any time, day or night. However, most customers say taking Tumble earlier in the day really helps with tackling afternoon fatigue.

Bottom line: Take your Tumble daily. Consistency beats perfection, every time.

The first thing some people notice is a change in energy, often relatively quickly. Tumble’s other benefits may be a little more gradual.

There’s no single timeline, as everyone adapts differently to the formula. What we do know is that consistency wins. We recommend taking Tumble for at least 90 days, with the vast majority of people noticing a meaningful difference within that time - most then choose to continue daily to maintain that feeling.

The British Society of Gastroenterology recommends a minimum of three months when trying a new bacterial product.

One capsule is only a fraction as good as two — not half as good.

It simply wasn’t possible to fit the full formulation into a single capsule. Even two was an enormous challenge.
Only a two-capsule serving allows the formulation’s benefits to be delivered as intended.

Tumble is one of only a few capsules in the UK successfully combining live cultures, enzymes, fibres, and micronutrients in one formula. We aren't suprised, fitting everything in while maintaining stability is no small task, particularly as enzymes and live cultures are difficult to keep shelf stable when combined.

Don’t like swallowing capsules?

Simply twist open the capsules and sprinkle onto (cold) food or into a drink.

We stand behind what we make, the formulation, and science that has gone into it. We don't feel right taking your money if you don't feel Tumble is adding value to your life.

If for any reason you decide Tumble isn't working for you within 30 days of your first order, return it for a full refund. 

Yes, you can. Tumble simply reduces the amount of supplements you take. We would also recommend omega-3 (with a high EPA & DHA content) to most people in the UK, unless you eat (oily) fish 3+ times per week. It wasn't possible to build this into Tumble.

When you take several supplements together, you’re effectively doing your own formulation — mixing ingredients without knowing how they interact. It’s bathroom chemistry, and the results tend to reflect that. Tumble means you need to take less supplements, some people only take Tumble.

Unless you’re a chemist, it quickly becomes guesswork. Ingredients don’t just sit side by side - they interact. Some compete for absorption, some influence each other, and bacterial strains can even suppress each other if poorly balanced with other ingredients.

That’s why real formulation relies on clinical research, academic data, and context. The decision to include an ingredient - and how much of it - is the result of weeks of careful consideration by experienced professionals, not simply adding things that sound beneficial in isolation.

You’re also relying on multiple manufacturers, each with different sourcing, quality standards, and levels of lab testing - increasing the risk of poor quality and impurities.
Tumble exists as a response to that. We only make one thing.

Everything is built as one considered system - with ingredients selected, combined, and dosed to work together, not just sit alongside each other.
