Deep Sleep Description
MySynapz is a French brand specializing in brain care, offering precision cognitive supplements made in France, combined with personalized diagnostics and a daily tracking app. Its formulas are developed with a leading R&D laboratory and a pharmacist specialized in naturopathy.
Deep Sleep is a complete sleep formula in HPMC vegetable capsules, designed to support the quality of nighttime rest in a gradual and natural way. Its synergy is based on two complementary phases of action: rapid evening relaxation thanks to traditional plants, and deeper regulation via an adaptogen and a functional mushroom.
This product is intended for adults who struggle to disconnect in the evening, experience frequent nighttime awakenings, or wake up tired despite full nights of sleep. It is suitable both for occasional use during stressful periods and as a continuous course to stabilize the sleep-wake cycle over time.
The formula is clean: GMO-free, gluten-free, with no colorants or preservatives, and with double quality control on raw materials and finished products.
Deep Sleep Composition
The Deep Sleep formula combines six active ingredients with complementary mechanisms, grouped into two areas of action:
Calming the mind and promoting sleep onset:
- Valerian: 2400 mg per dose, a traditional relaxing plant that interacts with the GABAergic system to promote relaxation and reduce nervous excitability
- Eschscholtzia: 550 mg, a relaxing plant that also modulates the GABAergic system to support natural sleep onset
Regulating stress and supporting nighttime recovery:
- Organic Ashwagandha KSM-66®: 200 mg, an adaptogen whose withanolides contribute to stress management and emotional balance
- Organic Reishi: 100 mg, a functional mushroom that contributes to stress reduction and helps maintain overall balance
Relaxing the body:
- Magnesium bisglycinate: 56.25 mg, contributes to the normal functioning of the nervous system and to the reduction of fatigue
- Vitamin D3: 5 µg, contributes to the maintenance of normal muscle function
The capsules are vegetable-based (HPMC), GMO-free, gluten-free, with no colorants or preservatives.
Origin of the Raw Materials
MySynapz selects its raw materials according to strict quality, traceability and safety criteria. Ashwagandha KSM-66® and Reishi are organic-certified, which is a notable differentiating point compared with many sleep formulas on the market.
Each ingredient is checked to verify its identity, purity and absence of contaminants. The raw materials are standardized and traceable. All manufacturing takes place in France, in a laboratory committed to an ISO 22000 certification process, with systematic microbiological analyses on each batch before market release.
How to Take Deep Sleep
The recommended dosage is 2 capsules in the evening, 30 minutes to 1 hour before bedtime, with a large glass of water. For profiles with very disrupted sleep, the brand suggests taking the 2 capsules 45 minutes before bedtime, combined with 5 minutes of deep breathing such as cardiac coherence.
Some practical tips to optimize the effects:
- Integrate the intake into a stable bedtime ritual, at the same time every evening
- Avoid screens 45 minutes before sleep
- Favor a cool, dark bedroom
The first calming effects may be felt from the first intakes. A stable improvement in sleep quality is generally observed between 1 and 2 weeks. Breaks are recommended between cycles: 7 days after 1 month of use, 10 to 15 days after 2 to 3 months.
The product is not recommended for pregnant or breastfeeding women, children under 10, or in cases of endocrine, liver or heart disorders. Do not drive after taking it.

My Opinion on Deep Sleep
Deep Sleep stands out for the precision of its formula. The dosages are clearly disclosed (2400 mg of Valerian, 200 mg of organic Ashwagandha KSM-66®, 100 mg of organic Reishi), which is rare in this category and reflects real transparency.
The organic certification of Ashwagandha and Reishi is a real strength. The two-phase logic (rapid relaxation followed by deeper regulation) is coherent and well constructed. Customer reviews confirm calmer nights, fewer nighttime awakenings and improved morning recovery. I recommend this product for adults looking for a natural, non-habit-forming solution to regain deep and regular sleep.
