Clinically tested ingredients:

GABA (1,500 mg)

GABA (gamma-aminobutyric acid) is an important neurotransmitter in the central nervous system. It helps regulate arousal, stress, and sleep. Balanced GABA activity in the brain is essential for mental calm, emotional stability, and the ability to fall asleep.

GABA deficiency often causes symptoms such as inner restlessness, difficulty falling asleep, anxiety, and a disrupted day-night rhythm.

According to Yamatsu et al. (2015), taking GABA orally significantly improves sleep quality. In the study, participants fell asleep faster, woke less often during the night, and felt more rested in the morning.

This is because GABA activates GABA-A receptors in the brain. These receptors are inhibitory. They dampen neuronal activity and thus promote deeper relaxation.

Moreover, according to clinical observations, GABA can lower salivary cortisol levels, which is particularly relevant for stress-related difficulty falling asleep. GABA is now considered a gentle, well-tolerated, non-addictive alternative to conventional sleeping pills. It is suitable both for people experiencing chronic stress and for those seeking natural support for their sleep architecture.

L-Glutamine (5,000 mg)

The placebo-controlled study by Castell et al. (1999) showed that L-glutamine improves immune system function in people under high physical stress. Athletes who supplemented with glutamine were less susceptible to infections after intense training than those in the placebo group.

A positive effect on recovery after exertion was also observed. Further research suggests that glutamine, as a precursor to neurotransmitters such as glutamate and GABA, may play an indirect role in regulating the central nervous system. These functions make glutamine an important component during recovery periods, particularly during increased physical or psychological stress.

L-Ornithine (1,500 mg)

According to Sugino et al. (2008), ornithine improves sleep quality in shift workers. It supports ammonia detoxification and contributes to mental recovery.

Ashwagandha KSM-66® (500 mg)

Langade et al. (2019) confirmed that this highly standardized extract lowers cortisol levels by up to 27% and significantly improves sleep quality in people with anxiety.

Ashwagandha KSM-66 sleep complex is proven to support deeper, more restful sleep. Studies show that Ashwagandha KSM66 lowers cortisol and promotes nighttime recovery.

Natural sleep thanks to Ashwagandha KSM 66 - without tolerance, with a scientifically proven effect. Ashwagandha weight gain: studies show a positive effect on muscle growth and appetite.

Gain weight naturally with ashwagandha - hormonal balance and better recovery.

Lavender extract (150 mg)

Kasper et al. (2010) demonstrated the effectiveness of lavender for sleep disorders. Its effects are similar to benzodiazepines - but without the risk of dependence.

Valerian extract (160 mg)

The meta-review by Fernández-San-Martín et al. (2010) shows an average reduction of 14 minutes in the time it takes to fall asleep and improved deep sleep with Valeriana officinalis.

L-Tryptophan (375 mg)

According to Lieberman et al. (1985), tryptophan improves serotonin levels in the brain, shortens the time it takes to fall asleep, and supports a stable mood without medication.

L-Arginine (2,000 mg) + Zinc (10 mg)

The placebo-controlled study by Lucotti et al. (2006) showed that daily L-Arginine supplementation over six months improves endothelial function, increases NO production, and lowers inflammatory markers. These vascular effects are considered the basis for improved blood flow and metabolic relief.

Zinc is an essential trace element involved in regulating neurotransmitters such as serotonin and has an antioxidant function in the central nervous system. According to Cherasse & Urade (2017), zinc promotes sleep quality, particularly when combined with magnesium and tryptophan.

Although there is no clinical human study explicitly examining the combination of L-Arginine + Zinc (so-called ArgiZinс) in relation to sleep, its synergistic effects on vascular function (L-Arginine) and neurotransmitter regulation (Zinc) are scientifically plausible. They are often taken together in dietary supplements for nighttime recovery and general nervous system support.

Magnesium (240 mg / 64% NRV)

In a randomized, double-blind, placebo-controlled study by Abbasi et al. (2012), researchers examined how magnesium supplementation affects sleep disorders in older adults. The results showed that taking 500 mg of magnesium daily for eight weeks was helpful. Sleep latency was significantly reduced. Nighttime wakefulness also decreased. In addition, total sleep time improved. Melatonin and cortisol levels also increased. This suggests a more stable circadian rhythm.

The study thus confirms magnesium’s role as a sleep-promoting mineral, particularly for people with mild to moderate sleep deprivation. Claims about the activation of GABA receptors were not directly demonstrated in this study and are therefore not scientifically established in this context.Zinc (10 mg / 100% NRV)

Cherasse & Urade (2017) showed improved serotonin synthesis and a shorter time to fall asleep when combined with magnesium and tryptophan.

Vitamin B6 (1.5 mg / 107% NRV)

Kennedy et al. (2010) showed improved cognitive performance under stress and reduced nervous irritability when taken together with magnesium.

Vitamin C (50 mg / 70% NRV)

Brody et al. (2002) showed that high vitamin C levels correlate with reduced anxiety and improved mood - crucial in cases of disturbed sleep.
