Migraines, loss of appetite, insomnia, fatigue, dizziness… the physical symptoms of stress and anxiety can vary from person to person, while impacting psychological balance and overall well-being. Faced with these issues, many people turn to tips or natural remedies, which are often insufficient when it comes to restoring lasting mental calm and deep relaxation.

Solazen: a natural alternative to help manage stress, anxiety and tension

Solazen is a unique combination of natural active ingredients formulated to help the body relax mentally and physically in situations of stress, nervousness and tension. Designed as rapid support in times of stress or strain, Solazen acts naturally in the body to promote a calmer, more stable state.
One of Solazen’s major strengths lies in its synergistic formula: a blend of carefully selected active ingredients that are natural and precisely dosed, providing a serious, coherent solution suitable for different profiles. This multi-active approach aims to support relaxation, mood and the ability to cope with more demanding periods.
The natural active ingredients in Solazen
GABA (gamma-aminobutyric acid)


Gamma-aminobutyric acid (GABA) is the main inhibitory neurotransmitter in the central nervous system of mammals and birds. A neurotransmitter is a chemical compound released by neurons that can act on other neurons.
The role of GABA is to slow down signal transmission in the nervous system. Without this stabilizing presence, neurons could transmit nerve impulses excessively. In adults, GABA helps limit prolonged, exhausting activation of neurons, while also playing a neurotrophic role (supporting the growth of certain neurons).

In terms of relaxation, GABA can help slow heart rate and support blood pressure. Its inhibitory properties promote a calmer response to stress-related imbalances. GABA is also associated with gentle relaxation, which can support a stable mood and restorative sleep. Conversely, a lack of GABA is often linked to mood disorders, difficulty with self-control and excessive worry.

The main dietary sources of GABA are sprouted foods (e.g. sprouted brown rice) and fermented foods produced by lactic bacteria (e.g. yogurt, cheese). It is also found in small amounts in certain raw foods (spinach, sweet potatoes, chestnuts). By way of comparison, to reach 600 mg of GABA, you would need to eat 2.34 kg of raw spinach or 1.53 kg of Pecorino cheese. Solazen provides around 133.33 mg of GABA per set of 4 sprays (which can be repeated up to 3 times per day), representing a real advantage in terms of intake, absorption and assimilation.
Numerous studies (see scientific information section) have examined GABA. A 2020 systematic review analyzed the effects of oral GABA administration on stress and sleep in humans, based on around fifteen human and animal studies. It concluded that natural and biosynthetic GABA intake can have beneficial effects on stress and sleep. (1)
Rhodiola rosea (adaptogenic plant)


Rhodiola rosea is a perennial plant, classified among adaptogenic plants. It meets three criteria: it is non-toxic, normalizing (supports balance) and capable of increasing the body’s overall resistance without overstimulating any specific organ.
Its root (rhizome) contains nearly 140 natural active compounds (vitamins, minerals, flavonoids, rosavin, salidroside, etc.). Some of these compounds, including rosavin and salidroside, are associated with anti-stress, anti-aging and immune-supporting properties. (2)
Solazen contains a standardized Rhodiola extract, in which rosavin (present at 5% in Solazen) is a rare phenolic glycoside found specifically in the rhizome. It is associated with adaptogenic, anxiolytic and antidepressant properties. (3)
Traditionally used to support emotional calm, Rhodiola rosea is helpful during stressful periods. It helps maintain a stable mood and a clear state of mind, especially when feeling under pressure. It is also appreciated for its benefits on mental performance (focus, attention).
Many studies have investigated this plant (see scientific information section). A Russian study conducted in the 2000s on students during exam periods showed that taking Rhodiola rosea extract significantly improved overall well-being and physical and mental condition. (4)
Scutellaria baicalensis (Scullcap)


Scutellaria baicalensis (Scullcap) belongs to the Lamiaceae family and holds an important place in traditional Chinese medicine. Native in particular to Russia and Siberia, it is rich in flavonoids, including:
- - Baicalein: a flavone with biomedical properties.
- - Baicalin: a flavone that acts on GABA receptors.
- - Wogonin: a flavonoid structurally similar to baicalein, associated with anticoagulant and antiviral properties.
These compounds contribute to the plant’s nutraceutical value. Scutellaria baicalensis is described as having a tranquilizing and relaxing effect, helping to balance nervous system activity, without undesirable side effects or sedative effects in the context described.
In the standardized extracts used in Solazen, baicalin is present at 70%. It is associated with relaxation and relief, and can support sleep phases without producing sedative effects.
A plant that has been widely studied (see scientific information section), Scutellaria baicalensis was notably evaluated in an animal study (December 2007) on stressed mice, looking at the absorption of Scutellaria baicalensis and Schizandra chinensis. The researchers concluded that both plants, in equal amounts, could be used to treat stress-related conditions. (5)
Vitamin B6


Vitamin B6 completes the Solazen formula. This B-group vitamin is essential for proper body function and is particularly involved in the synthesis of neurotransmitters, amino acids and red blood cells. Several active forms of vitamin B6 exist in the body (pyridoxal, pyridoxine, pyridoxamine, pyridoxal-5-phosphate, etc.).
- Vitamin B6 is a water-soluble (water-soluble) B-group vitamin.
- It is found in meat (turkey, lamb, veal, chicken), fatty fish (cod, salmon, tuna) and organ meats.
- It is involved in the synthesis of neurotransmitters, amino acids and red blood cells.
- When consumed in excessive amounts, pyridoxine can be toxic for the body.
- Vitamin B6 is the cofactor of the enzyme that converts glutamate into GABA.9
Vitamin B6 has been the subject of many studies. A simple-blind randomized clinical trial (2018) in healthy adults with severe stress assessed magnesium and vitamin B6. The conclusion suggested, in subjects suffering from severe to extremely severe stress, clinical support in favor of greater benefit from magnesium combined with vitamin B6. (6)
Why Choose Solazen Over Other GABA (Gamma-Aminobutyric Acid) Extracts?
To start, Solazen features a natural blend of GABA, Rhodiola Rosea, Baikal Skullcap, and Vitamin B6. Each component brings its own unique benefits and characteristics:
- GABA, a natural inhibitory neurotransmitter, helps alleviate anxiety symptoms and enhances sleep quality.
- Vitamin B6 (included in Solazen) supports normal psychological function and the human nervous system.
- Rhodiola Rosea, enriched with its active compound rosavin, promotes emotional calm during periods of occasional stress.
- Baikal Skullcap, another plant in Solazen, is rich in flavones and is a scientifically recognized, highly effective natural stress reliever.
- The combination of GABA and Vitamin B6 is highly beneficial: GABA is produced in the brain from glutamate with the help of the enzyme glutamate decarboxylase (GAD), which uses Vitamin B6 (in the form of pyridoxal-5’-phosphate) as a cofactor.
- The Baikal Skullcap extract selected for Solazen is known for its potent antioxidant, anxiolytic, and even antidepressant effects.

GABA
With the chemical formula C4H9NO2, gamma-aminobutyric acid is found throughout the brain. Additionally, it is active in about 30 to 40% of synaptic connections in the central nervous system, including the brain, cerebellum, and spinal cord.

There are two main types of GABAergic receptors: the GABA A receptor (located in the cerebral cortex and cerebellum) and the GABA B receptor (found in the thalamus, cerebellum, and spinal cord). To reduce neurotransmitter release, GABA interacts with its receptors. When activated, neurotransmission inhibition begins, inducing a chloride ion flow in GABA A receptors and a calcium ion flow in GABA B receptors simultaneously.
Its various relaxing and sedative properties, along with its effects on the brain, have been scientifically demonstrated multiple times. Here are two examples:
- Effect on the brain (7): A 2016 review conducted by two scientists titled “GABA Receptors in Brain Development, Function, and Injury.” This comprehensive review, citing nearly a hundred scientific references, explains the structured role of γ-aminobutyric acid in the brain. The findings reveal that GABA:
- “Acts as an excitatory agent involved in many neurogenesis processes, including neuronal proliferation, migration, differentiation, preliminary circuit formation, and the development of critical periods.”
- “Also plays a role in the development of interstitial white matter neurons and oligodendrocytes.”
- “GABAergic system developmental anomalies are particularly relevant in the etiology of schizophrenia.”
- “The review also explores GABA’s potential role in mature brain injuries, such as transient ischemia, strokes, and traumatic brain injuries/post-traumatic epilepsy.”
- etc.
- Oral Relaxing Properties (8): A 2016 study by Japanese researchers on “The Effect of Oral γ-aminobutyric Acid (GABA) Administration on Sleep and Its Absorption in Humans.” Sleep was evaluated using electroencephalography after oral GABA administration. The results showed that GABA was quickly absorbed, with the highest blood concentration 30 minutes after ingestion, followed by a subsequent decrease. This validates its oral relaxing effects.
Baikal Skullcap (Scutellaria baicalensis)
Baikal Skullcap is a plant rich in flavonoids (flavones) with proven anti-stress effects. It acts quickly and has antioxidant properties:
- Enhances SOD (superoxide dismutase) levels
- Reduces lipid peroxidation, with ROS quickly detected in blood plasma
The flavones of Scutellaria are detected very rapidly in blood plasma after oral intake, with baicalin even appearing within 15 minutes. (9)
The Various Mechanisms of Scutellaria baicalensis (4):
1. Neuroinflammation:
Regulates the expression of inflammatory mediators
Inhibits NF-κB activation
Reduces nitric oxide (NO) production
2. Antioxidant Activity:
Enhances SOD (superoxide dismutase) levels
Reduces lipid peroxidation and ROS
3. Anxiolytic and Antidepressant Effects:
Inhibits MAO-A and MAO-B (monoamine oxidase)
Modulates the GABA-A receptor
4. Beta-Amyloid:
Inhibits cholinergic marker generation
Prevents cell death
5. Cerebral Ischemia:
Reduces ROS levels
Inhibits pro-inflammatory cytokines
Decreases nitric oxide production
Reduces oxidative stress
Lowers caspase 3 activity
One of the main flavonoids, baicalin, has been studied for its real effects on depressive and anxious behaviors. For instance, a July 2017 animal study conducted on rats under depressive-like conditions (reduced sucrose intake, lower locomotor activity, increased immobility) demonstrated significant improvements after baicalin treatment (20, 40 mg/kg).
The study specifically confirmed that baicalin has an antidepressant effect, likely linked to the inhibition of NLRP3 inflammasome activation in the rat prefrontal cortex. (10)
Rhodiola Rosea (also known as Golden Root):
Effects of Rhodiola rosea extract on the central nervous system (preclinical studies):
- Rapid activation and long-term effect: The EEG profile is similar to that of caffeine, guarana, and Ginkgo biloba. (11)
- Memory: Golden root enhances long-term potentiation (LTP) in the hippocampus, associated with improvements in spatial and temporal memory.
- Neuroprotection: Modulation profile shows significant upregulation of three GPCR genes, suggesting enhanced spatial and temporal memory.
Clinical Study on Rhodiola Rosea: In a randomized, double-blind, placebo-controlled trial, 60 participants suffering from stress-related fatigue were given 576 mg of Rhodiola extract daily or a placebo for 28 days. Results: a small but statistically significant improvement in burnout scores on the Pines scale, along with a non-significant enhancement in physical and mental health on the SF-36, and no apparent effect on depression scores on the MADRS.
Second Clinical Study on Rhodiola Rosea: Among 10 participants, Rhodiola rosea significantly reduced anxiety, as shown by lower Hamilton scale scores. (12)
Vitamin B6
Vitamin B6 impacts several factors in the human body:
- Normal energy metabolism
- Proper functioning of the nervous system
- Normal synthesis of cysteine and homocysteine metabolism
- Reduction of fatigue
- Normal glycogen and protein metabolism
- Normal mental functions
- Red blood cell formation
- Proper immune system functioning
- Regulation of hormonal activity

Solage recommends:
- Most of our nutrients come from France or Europe (local is a priority), except when we can't do otherwise (for curcuma, for example). We never choose ingredients from places or countries where quality is not assured and workers are poorly paid.
- Solage products are designed in France and manufactured according to GMP (Good Manufacturing Practice) standards from the pharmaceutical industry and the HACCP (Hazard Analysis Critical Control Point) method, developed by NASA.
Both methods implement procedures, documents and controls to guarantee perfect traceability and the absence of biological or chemical contamination.
- Solage is a French company, and its products are registered with the relevant authorities.
Solage products are safe, with no bad surprises.
To answer this question, we distinguish between three types of product, depending on their nature and intended purpose:
1/ Ideally taken as a continuous treatment: those which compensate for a nutritional or age-related deficiency, and which serve to restore the body's functions without altering its normal metabolism.
- Common nutritional deficiencies: marine omega-3, vitamin C, magnesium, vitamin D between October and May
- Age-related or pathological deficiencies: Ubiquinol, Glutathione, Iron, Collagen (type I and II)
- To help the body deal with underlying problems: Saffron, Ashwagandha, Men's and women's urinary comfort, cholesterol
2/ To be taken in a cure, but where a break is not necessarily necessary if you or your healthcare professional find it useful:
Detox: Milk thistle, Glutathione
Digestion: Probiotics
3/ Products where a break is useful:
- Curcumin: at least a break of a few days between each box, as it modifies metabolic pathways in the body
- Echinacea (immunity): a break of a few days between each box so as not to over-stimulate the immune system
- Melatonin: avoid taking it every day over the long term, so as not to habituate the body.
In all cases, it's important to remember that the products we offer are genuinely active, that it's important to respect dosage and that they are not a substitute for a varied, balanced diet and a healthy lifestyle.
This will of course depend on the product and your physiological state.
It's worth remembering that physiology is a long-term process, and that it generally takes two to three months, sometimes longer, to achieve a profound change.
However, the feeling is generally quicker, between 15 days and two months.It is then necessary to continue to try to fix these initial results in greater depth.
However, this will be much quicker with subsequent products:
- Melatonin and sublingual GABA, which have a very rapid onset of action (between two minutes and 30 minutes)
- Probiotics (48 hours to two weeks))
Please refer to the “Scientific studies” section of this product page, where you'll find most studies on bioavailability and medium-term effects.
