Your Benefits

🧑‍🍼 Supports fertility & reproductive outcomes

From the age of 30, women have already used up around 90% of their ovarian reserves - unfortunately, the biological clock ticks against fertility from the thirties onwards. This makes it all the more important that the remaining eggs are provided with optimal conditions for fertilization. However, healthy reproductive mucous membranes are often an obstacle, as inflammation and dysbiosis make conception more difficult. happy | ONE was specially developed to combine substances that support healthy & fertile mucous membranes and combat underlying dysbiosis.

🕰️ Slows down reproductive ageing processes

Unfortunately, the reproductive capacity of women ages 6x faster than that of men. We think that's unfair! Science is now clear that inflammation and dysbiosis (a disrupted microbial ecosystem, which occurs often in women facing fertility issues) play a particularly important role in tissue & reproductive ageing. happy | ONE addresses both mechanisms in order to positively influence them and thus slow down reproductive ageing for women.

🧫 Helps artificial fertilization & egg freezing

Studies show that the success rates of artificial insemination are significantly higher with a healthy reproductive microbiome. Every artificial insemination should therefore not only include hormonal treatment - but also support for the microbiome. happy | ONE has properties that can positively influence the reproductive microbiome and thus increase the likelihood of success thanks to pre- and probiotic substances. In the case of social freezing / egg freezing, the period up to the artificial implantation of the egg should be bridged by the targeted supply of microbial substances in order to counteract a deterioration of the reproductive microbiome.

🦠 Supports vaginal health & immunity

It is now well known that a healthy "vaginal flora" is important to protect against recurring infections such as bacterial vaginosis or UTIs, as well as fungal infections. Doctors are also increasingly turning to alternatives to antibiotic therapy and see the vaginal microbiome as an important key to the female immune system. happy | ONE is developed to support these positive properties on vaginal health and build a stable basis for intimate immunity.

🔬 Scientifically developed, based on studies & sustainably produced

Developed based on the expertise of leading OB/GYNs, reproductive doctors and microbiologists. happy | ONE is rooted in over 20 years of reproductive & longevity research. Transfer of the oral intake into the reproductive tract and the colonization of "healthy" bacterial cultures in the reproductive tissues are clinically tested and confirmed. We only use environmentally friendly packaging & high-quality certified production. We really care for our planet and customer saftey.

Reproductive Microbiome known from


Happy ONE combines study-proven substances and active ingredients to support reproductive possibilities.

Made by Science to build the basis for reproduction.

Probiotic Nyx Complex

Research shows that the administration of precisely selected probiotics, can facilitate the restoration of symbiotic microbiota to increase successful conception and assisted reproductive technology outcomes. Our unique mix of probiotics, that easily can be taken orally but accumulate in the reproductive system, showed positive results on the health of the reproductive mucous membranes and their function. Our mix is specially selected to support your reproductive properties and slow down reproductive ageing.

Prebiotic Inulin

Prebiotic substances provide a basis for the "nutrition" of bacterial strains, which are important for a stable reproductive ecosystem. Our prebiotic formulation contains inulin from native chicory as the basis for the growth of our probiotic complexes & their optimal function. In addition to positive properties on the bacterial helpers, Inlun contributes to normal intestinal function. Our little add-on.


Also known as vitamin B3. Niacin, essential for energy production, DNA repair, and mucous membrane health, plays a vital role in reproduction, cellular metabolism and longevity. It’s a well studied precursor to NAD+, a coenzyme essential for cellular processes. NAD+ declines with age. Unlike popular NAD+ boosters (NMN or NR), Niacin has been thoroughly studied in human trials for decades, and has been shown to cure NAD+ deficiencies in humans and to contribute to the maintenance of normal mucous membranes. An essential for your reproductive tissues.

Vitamin C

Studies indicate that low of vitamin C induces a state of subfertility, reduces overall fecundity, and adversely impacts both pregnancy outcomes and growth in the offspring. Besides it's high antioxidative effects, vitamin C contributes to a normal collagen formation which is essential for the tissues of the reproductive tract. Furthermore it supports the normal function of the immune system and protection of cells from oxidative stress.
