#1 Liquid Skin Probiotic
Multi Strain Biotic
A live liquid probiotic formulated to support the gut–skin connection and calm inflammation from within.
/ One month's supply
Support your gut and skin health with our 100% natural probiotic, free from artificial ingredients, preservatives, and added sugars. Our advanced, award-winning multi strain blend contains 15 bio-live cultures, designed to restore beneficial bacteria and promote a balanced gut microbiome. A healthy gut is essential for digestion, immunity, and skin clarity, thanks to the powerful connection known as the gut-skin axis.
70% of our customers saw clearer, healthier-looking skin with daily use of our probiotic*.
While live cultures work to rebalance the microbiome, our unique Skin Clear Complex formula is also enriched with skin-nourishing herbs and vitamins – including aloe vera, apple cider vinegar, bilberry, co-enzyme Q10, ginger, hibiscus, Oregon grape, turmeric, vitamin C, and more — to support a radiant complexion from within. These carefully selected ingredients help reduce inflammation, enhance collagen production, and strengthen the skin barrier, ensuring a clearer, healthier glow.
This naturally brewed probiotic may be slightly fizzy when first opened due to shaking during transit; please open it slowly to release the air. Small particles may develop in the bottle over time – as a naturally brewed product, this is perfectly normal.
Please note: as part of our ongoing commitment to sustainability, we no longer include security stickers on our outer tube packaging.

Benefits of taking our Multi Strain Biotic
“I didn’t set out to create a probiotic. I set out to heal my skin.”
After years of struggling with psoriasis and eczema, nothing I applied topically ever truly resolved things for good. Looking back now, what changed everything was understanding the gut–skin axis and consciously supporting my gut health day after day.
As I dove deeper into the microbiome, the picture became sharper: freeze-dried cultures in capsules face a hostile journey—stomach acid first—and many strains never arrive where they matter. If probiotics can’t reach your gut intact, how can they do their job?
That realisation drove me toward a live, liquid ferment: a fermented Multi Strain Biotic that works WITH your digestion, crafted to nourish the microbiome foundations that underpin calmer digestion, immunity, and radiant skin.

Frequently Asked Questions
See All FAQsThe Multi Strain Biotic is suitable for everyone, including those on a gluten-free or vegan diet, pregnant or breastfeeding (however, we always recommend checking with your healthcare provider first as they know you and your bump best).
If you have any ongoing health concerns or on any medication, we always recommend consulting with your doctor before starting any new probiotic products.
For children, it is suitable for all ages – we recommend 1-2 teaspoons for 7+ and 5 drops for under 7 years of age. If taste is an issue, we recommend diluting in a small amount of apple juice.
Your skin and gut are closely connected through what's known as the gut-skin axis. When your gut microbiome is balanced, it can help reduce internal inflammation, support immune function, and improve nutrient absorption — all of which play a key role in healthy, clear skin.
Our Multi Strain Biotic supports the growth of beneficial bacteria in your gut, which in turn helps promote healthier skin. That said, many of our customers also take it for broader wellbeing — whether to support immunity, aid digestion, or simply feel their best from the inside out.
Our Multi Strain Biotic isn’t a quick fix — it’s a long-term investment in your health. Even if you don’t notice results right away, rest assured the beneficial bacteria are busy working behind the scenes to support your gut from day one.
Everyone is unique so there’s not a one-size-fits-all answer, but many people begin to notice improvements within 1-3 months of consistent use. Subtle shifts — like better digestion, clearer skin, or more balanced energy — often happen gradually as your gut microbiome rebalances.
We recommend taking the Multi Strain Biotic consistently for at least 3 months, as this is when most people begin to see meaningful results. That said, gut health is an ongoing journey — not a one-time fix. Staying consistent beyond the 3-month mark helps maintain progress and support lasting, long-term benefits.
Remember, your gut microbiome is unique to you, so everybody’s experience varies.
For optimal results, we recommend taking first thing in a morning on an empty stomach, 30 minutes before any food or drink. This helps the live bacteria reach your gut with minimal interference, supporting better absorption and overall effectiveness.
The dose for adults is 15ml (one tablespoon) daily, we recommend using a measuring tablespoon or a shot glass for accurate dosage. To make it part of your routine, try habit stacking — take it alongside a morning habit you already have, like brushing your teeth or prepping breakfast. It’ll soon become second nature.
Our probiotic can be stored in a cool, dark place or in a fridge – whichever you prefer.
