Daily rush, sensory overload, and difficulty concentrating overload the nervous system. Stress Formula combines three studied plant-based ingredients: Serenzo®, saffron, and L-theanine — as well as vitamins B5 and B6 — to support calm, focus, and natural emotional balance.
Serenzo® acts on stress in multiple ways: it regulates dopamine D2 receptors and supports GABA activity — the body’s natural calming mechanisms. In clinical studies, it demonstrated a 50% reduction in emotional stress and a 62% reduction in perceived anxiety.
Saffron improves mood and emotional stability — without drowsiness and without a “heavy head” in the morning.
L-theanine works quickly (30–60 minutes), calms racing thoughts, and supports focus without tension.
Vitamins B5 and B6 strengthen the nervous system and help regulate the body’s response to stress.
The result?
Less stress, more stable emotions, and greater inner balance — exactly when you need it.
Stress Formula was designed as real support for people living at a fast pace — overloaded, overstimulated, and exposed to chronic stress. Studies on its key ingredients confirm improvements in well-being, focus, and regulation of tension.
Less stress — by up to 50%
In a clinical study with Serenzo®, a 50% reduction in emotional stress was demonstrated after 6 weeks of supplementation. It is natural support that works “at the source” — via CB2 receptors.
Saffron is one of the most thoroughly researched plant-based ingredients for mood. Studies confirm that it reduces emotional tension, improves well-being, and makes it easier to fall asleep — without morning sluggishness.
L-theanine increases alpha waves in the brain, supporting a state of relaxation combined with alert concentration. The effects usually appear after 30–60 minutes.
Serenzo™
A natural extract from the peel of sweet orange, standardized to 20% d-limonene. It acts directly on dopamine D2 receptors — the ones that regulate the body’s response to stress. When dopamine levels drop (e.g. due to chronic stress or high cortisol), tension, irritability, and low energy appear. Serenzo™ helps reduce excessive nervous system activity, restores dopamine balance — supporting greater calm and mental clarity — and supports GABA activity, the body’s natural “stress brake.”
It acts both neurologically (dopamine, GABA) and physiologically (alpha-amylase), helping the body cope with stress at the level of both emotions and physical response.
Saffron extract
Natural mood support. Studies confirm that saffron helps maintain emotional balance, reduces tension, and makes it easier to fall asleep — without morning drowsiness. Ideal during PMS, mental overload, and chronic stress.
L-theanine (green tea extract)
Supports alpha waves in the brain, which are responsible for a feeling of calm and focus. It helps reduce tension, calms racing thoughts, and supports mental comfort — without causing drowsiness. Gentle, fast-acting, and ideal as “calming support during the day.”
Vitamin B6
Supports normal nervous system function and helps reduce tiredness and fatigue. It is involved in regulating hormonal activity and supports energy metabolism — especially important during periods of stress and heavy physical or mental strain.
Vitamin B5
Helps with the proper synthesis and metabolism of steroid hormones, vitamin D, and neurotransmitters — supporting a healthy stress response. It contributes to the reduction of fatigue and supports energy metabolism, helping maintain balance during demanding moments of the day.

How does Stress Formula work?
Stress Formula works on multiple levels. Serenzo™ supports the body in regulating the stress response — both physical (tension, overactivation) and behavioral (reactivity, difficulty concentrating). D-limonene from Citrus reticulata acts on nervous system receptors involved in the stress response, while saffron, L-theanine, and B vitamins support mood and emotional balance.Has your dietary supplement been tested?
Safety and quality are our top priorities. The Stress Formula dietary supplement has been tested for molds, yeasts, and bacteria (including Escherichia coli, Staphylococcus aureus, and Salmonella), as well as PAHs and heavy metals (lead, cadmium, mercury). We have also tested our product for the absence of gluten and lactose. The tests were conducted by the independent, certified laboratory J.S. Hamilton Poland — the results are fully published on this website in the “Health and Safety” section.How soon will I see results?
Many women notice the first changes after just 3–7 days: reduced tension, greater calm, and less “racing thoughts.” The fullest effects (mood balance, better stress tolerance, and greater emotional comfort) usually appear after 3–4 weeks of regular supplementation.Can I take Stress Formula every day?
Yes. The ingredients act gently and show the best effectiveness with regular use. You can take Stress Formula daily — also for a longer period of time, as recommended.It does not cause drowsiness or dependence, so it is also suitable for daytime use.
Does Stress Formula work if I’m very stressed or during PMS?
Yes. Serenzo™, saffron, and L-theanine support the body especially during periods when stress is at its highest: before menstruation, during intense work, chronic tension, or emotional overload. Regular use enhances the effect.Can I combine Stress Formula with other Natu.Care supplements?
Yes — Stress Formula works well with most Natu.Care products. Best combinations:- Magnesium – for nervous system support and evening calm,
- Omega-3 – for mood, stress resilience, and focus,
- Vitamin D3+K2 – for immunity and hormonal balance,
- Collagen – for skin support and regeneration during periods of fatigue.
