A prebiotic effect.

Tło
CORTISOL LEVEL REGULATION

The manufacturer’s study showed that Safr’Inside™ and its active compound, safranal, modulate the body’s biological response to stress(3). Similar effects were observed in studies conducted by the manufacturer of L-theanine(8-10).

A fast physiological response – in under 30 minutes.

The manufacturer’s ex vivo study showed that Safr’Inside™ reduces inflammation in intestinal and joint cells – demonstrating a systemic anti-inflammatory effect(3).

Tło
A STABLE NERVOUS SYSTEM AND ENERGY

Niacin supports the normal functioning of the nervous system(5) and psychological function(7). It also helps reduce feelings of fatigue and tiredness(4) and supports normal energy metabolism(6).

BETTER SLEEP – WITHOUT DAYTIME DROWSINESS

The manufacturer’s study of Safr’inside™ showed that it improves sleep quality, shortens time to fall asleep (by 35.4%), and supports overnight recovery(11,12). In studies, saffron extract delivered effects comparable to melatonin – without the side effects typically associated with supplementation with the sleep hormone(13).

Works naturally, without dependence or mental fog – supports calm in the evening while maintaining alertness during the day.

SUPPORT IN PREMENSTRUAL SYNDROME (PMS)

The manufacturer’s study of saffron extract showed a significant reduction in PMS symptoms – including irritability, tension, and mood swings(15).

Improvements were observed after just two cycles.

SUPPORT DURING (PERI)MENOPAUSE

In a 12-week manufacturer-led study, saffron extract significantly reduced symptoms of anxiety and low mood in perimenopausal women – by over 30% compared to placebo(16).

REDUCTION OF DEPRESSIVE SYMPTOMS ON THE POMS SCALE

In manufacturer-led studies comparing Safr’Inside™ with standard pharmacological approaches, an improvement in depressive symptoms on the POMS scale was observed after 8 weeks of Safr’Inside™ use.

Effects were noticeable as early as 6 weeks.

Why don’t we use ashwagandha?

Insufficient scientific evidence

Ashwagandha has seen a rapid rise in popularity – in recent years, it has appeared in thousands of dietary supplements across Europe and is promoted as a natural solution for stress, fatigue, insomnia, and low mood. However, this popularity is not supported by sufficient scientific evidence confirming either its effectiveness or its safety.

Denmark warns against ashwagandha

In 2020, according to an assessment by the Danish Technical University (DTU), ashwagandha was classified as potentially unsafe because it may disrupt hormonal balance and reproductive function in both men and women. It may also negatively affect metabolism, the immune system, and the central nervous system. Denmark recommended removing ashwagandha from the market. In response, a report was published in 2024 by an expert committee appointed by India’s Ministry of AYUSH, intended to defend the safety of ashwagandha. However, this document does not meet clinical evaluation standards – it is based on a review of existing studies without assessing their quality or applying rigorous methodology. India is one of the largest exporters of ashwagandha to Europe, and the ingredient holds significant economic and symbolic importance there.

Warnings from Germany

Serious warnings have also come from Germany. As early as 2013, the Federal Institute for Risk Assessment (BfR) pointed to a lack of toxicological data and recommended considering restrictions on the use of ashwagandha in food products. In an opinion reaffirmed in 2024, BfR warned of a risk of liver damage and potential effects on the hormonal system. Particular concern was raised for children, pregnant women, and individuals with liver disease. At the same time, BfR emphasized the lack of clear evidence supporting the claimed health benefits.

Iceland, France, and the Nordic countries – shared concerns

Concerns about the safety of ashwagandha have also been raised by public health authorities in other European countries, including Iceland, France, and the Nordic countries, where restrictions or further risk assessments have been suggested.

Standards not met

At present, most available studies on ashwagandha do not meet the standards applied to ingredients intended to act on the nervous or hormonal systems. Randomized clinical trials in humans are limited, often conducted on small groups, with inconsistent results and weak methodological quality.

Interactions with other medications

Ashwagandha may also interact with sedative, anxiolytic, or anticonvulsant medications, intensify side effects, and affect sex hormone levels – making it contraindicated, among others, in thyroid disorders or hormone-dependent cancers. Until studies meeting modern clinical standards are available, ashwagandha remains an ingredient with an unverified safety profile – with many unknowns and potentially serious health consequences.

Frequently asked questions

When can I expect the first effects?

The first effects? Even in under 30 minutes. Manufacturer-led studies have shown that Safr’Inside™ and its active compound, safranal, modulate the body’s biological response to stress(3) and help maintain nervous system balance and heart rate variability in stressful situations(2).

Other effects require more time and consistency. A manufacturer-led study of Safr’Inside™ showed a reduction in depressive symptoms on the POMS scale after 8 weeks of use.

Can the gummies be taken daily?

Yes. The recommended serving is 3 gummies per day, taken at any time of day.

Is the product habit-forming or does it cause daytime drowsiness?

No. Manufacturer-led studies of Safr’inside™ showed improvements in sleep quality, a shorter time to fall asleep (by 35.4%), and support for overnight recovery(11,12). In studies, it delivered effects comparable to melatonin – without the side effects typically associated with supplementation with the sleep hormone(13). It works naturally, without dependence or mental fog – supporting calm in the evening while maintaining alertness during the day.
