9 mealsLots of brands use oats and seeds. That doesn't automatically make them true overnight oats.
Many are just instant porridge mixes, protein powders, or sweetened oat puddings that are "ready in 60 seconds." Some don't actually change overnight at all.
Oat Cult is designed specifically to transform over 8+ hours. The fibre hydrates properly. The texture changes. Resistant starch increases. The probiotic survives and works with the oats.
It's not just oats in a bag. It's formulated for the overnight process.
Are they gluten-free?
Yes, our overnight oats are gluten-free. We use certified gluten-free oats and ensure that our production facilities maintain strict standards to prevent cross-contamination.
Are they vegan?
Absolutely! Our overnight oats are 100% vegan-friendly. We do not use any animal-derived ingredients in our products.
Are you sweetened with syrups like other brands?
No. We don't use added sugar, syrups or artificial sweeteners. The sweetness comes naturally from dates and real ingredients.
Some brands claim "no added sugar" but still use things like fruit syrups, concentrates or sweetened yoghurt bases. Technically that can still qualify, but it often means a much higher sugar load.
We keep it simple. No syrups. No concentrates. No hidden sweetness tricks. Just naturally occurring sugars from whole ingredients.
Each serving contains 1 billion CFU of Bacillus subtilis DE111, a clinically studied, spore-forming probiotic strain.
Unlike many probiotics found in chilled products, this strain survives stomach acid and reaches the gut alive.
It's stable at room temperature and remains viable throughout shelf life.
How many calories are in a serving?
A 60g serving is around 230 kcal, depending on flavour. Cacao is 238, Cinnamon 233, Strawberry & Goji 228.
Between 7.5g and 8g per serving, before you add milk. We don't bulk it out with cheap protein powders to chase a number on the front of pack. If you want more, add your milk of choice and a scoop of your favourite protein and build it up how you like.
Yes we're high in fibre: 8g to 9g per serving. A bowl of Cacao gets you nearly a third of your daily fibre before you've added a thing.
Yes.
Each 60g sachet contains around 8g of fibre, including naturally occurring beta glucan from oats.
That is over a quarter of the recommended 30g daily fibre target in one serving.
Most UK adults do not get enough fibre. Oat Cult makes it easy to start the day properly, without powders, syrups or artificial extras.
Your night-time ritual
30 seconds tonight. Breakfast sorted by morning.
Pour
Empty your chosen Oat Cult pack into a jar or bowl. Any vessel will do—no judgment here.
Fill
Add your favourite milk (yoghurt) or alternative until the oats are just covered. Stir gently to make sure every oat gets some love.
Enjoy
Leave overnight for maximum magic—or dig in straight away if you can't wait. Heat it up if that's your thing.
Why overnight?
Soaked, not stirred.
Fuller for longer
Eight hours soaking in cold milk turns the oats into something else entirely. Stays with you. Doesn't bail on you at 11.
Slow-burn fuel
The kind of slow-release energy endurance runners pay good money for. We just leave the oats in milk.
Pre-workout, done properly
Fibre and slow-burn carbs — what your body actually needs before training. We didn't shove in cheap protein to make a bigger number on the front. Want some? Add your own scoop. We won't be offended.
Chants of the cult
I became so obsessed with improving my gut that I started a cult
Most overnight oats are sad. Chalky. Bland. Secretly full of sugar.
So we locked ourselves away with 1 billion live bacterial cultures and didn't leave until we'd built something worth worshipping.
The result? Overnight oats with zero added sugar, real ingredients and gut health that actually works, just add milk, sleep, wake up enlightened.
The cult is growing. Your gut is waiting.
The science ofDE111.
Most probiotics never reach your gut alive. The Lactobacillus and Bifidobacterium strains in chilled yoghurts and supplements are vegetative cells, fragile by design, mostly destroyed by stomach acid. You can swallow 20 billion and only a fraction make it through. Bacillus subtilis DE111® is different. It's a spore-forming probiotic, encased in a natural shell that survives the acidic stomach. In an ileostomy clinical study DE111 spores appeared in the small intestine within 3 hours and germinated to live cells by hour 6. That's the moment your gut actually gets to work.

| Refrigeration needed | No | Yes |
| Shelf life at room temp | 24 months | Days to weeks |
| Effective dose | 1 billion CFU/day | 10–20 billion CFU/day |
| Genome sequenced | Yes | Variable |
