100% natural. We believe less is more. We are committed to making science-backed probiotics accessible to everyone.

Exclusive formula

Carefully selected strains for each formula, combined with beneficial nutraceuticals to address specific pathologies. Moreover our high-precision jar has been specially designed to guarantee the shelf life and recommended quantity of our probiotic strains.

Shelf stable | High CFU | Lyophilised

Our probiotics undergo shelf-life studies of up to 2 years, ensuring that the strains and the stated amount of at least ≥1×10^9 CFU remain effective throughout the product’s shelf life. The lyophilized form preserves metabolically inactive bacteria, which, when hydrated, reactivate to deliver their beneficial effects.

You are never truly alone

Your body is home to trillions of microorganisms that live in perfect harmony with you. Approximately 1 to 2 kg of an adult’s body weight consists of bacteria, meaning that for every human cell, there are roughly 1.3 bacterial cells. This essentially means you are more bacterial than human!

Many of these bacteria live as commensals, while others, particularly those abundant on the skin and in the digestive tract, make up what is known as the human microbiome—a complex ecosystem that performs some of nature's most crucial tasks and plays a vital role in your health.

Every part of the human body contains bacteria, although they are particularly abundant on the skin and in the digestive tract. Approximately 1-2 kg of an adult’s body weight is made up of bacteria that cohabit with them and perform some of nature's most crucial tasks.
In fact, you’re more bacterial than human! For every human cell, there are approximately 1.3 bacterial cells in your body.

From the moment you're born, you're exposed to bacteria.
Over time, your microbiome balances and stabilizes.
But when this balance is disrupted—a condition known as dysbiosis—your well-being can be at risk. Dysbiosis occurs when is an imbalance in the microbiota . This balance can be disrupted by factors such as age, diet, physical or physiological stress, diseases, antibiotics and more.
In the last years, there has been an explosion of knowledge regarding the relationship between dysbiosis and many diseases (nervous system disorders, allergies, skin issues like acne and psoriasis, obesity ,diabetes, Crohn´s…), and the possible mechanisms by which microbiota can affect the origin and evolution of some pathologies, especially those of multifactorial origin, are being investigated.

Which are the main benefits of probiotics?
Probiotics are live microorganisms that, when taken in the right amounts, offer significant health benefits.
INTESTINAL EQUILIBRIUM: Probiotics are key to maintaining this balance and optimizing intestinal function.
IMMUNE SYSTEM: The gut microbiota partially influences the immune response, with probiotics playing a key role in preventing infections and alleviating allergy symptoms.
DIGESTIVE HEALTH: Probiotics help mitigate issues like diarrhoea and constipation, promoting healthy digestion.
SKIN CARE: The gut-skin relationship suggests that microbiota changes may cause conditions like dermatitis or psoriasis, with probiotics helping to improve these symptoms.
