About Sleep.
Terraphy is a French brand of liquid supplements made with functional mushrooms, fully grown and formulated in its own Normandy laboratory, with no subcontractors. Its formulas are developed by a doctor of pharmacy and ultrasound-extracted to preserve the full spectrum of active compounds.
The Sleep. cure is a sublingual liquid tincture built around organic Normandy reishi (Ganoderma lucidum), combined with passionflower and L-tryptophan. It comes in a 30 mL bottle with a graduated pipette, for precise dosing at every evening intake.
Its technical features as confirmed by the official website:
- Organic reishi fruiting body, ultrasound-extracted
- Base of osmosis water and organic vegetable glycerin, alcohol-free
- No additives, no solvents, no mycelium
- EU certified organic, vegan and gluten-free
- Non-habit-forming, with no morning grogginess on waking
The Sleep. cure is aimed at people looking to support natural sleep onset and improve the quality of their nights. Passionflower contributes to normal sleep. L-tryptophan contributes to the synthesis of serotonin, essential to a balanced sleep-wake cycle.
Sleep. composition
Per 2 mL, the Sleep. cure provides:
- Reishi (Ganoderma lucidum, organic fruiting body): 800 mg
- Passionflower (Passiflora incarnata): 600 mg
- L-Tryptophan: 220 mg
The full ingredient list published on the official website is as follows: purified water, organic vegetable glycerin, organic reishi fruiting body extract (Ganoderma lucidum), passionflower powder (Passiflora incarnata), L-Tryptophan.
The formula contains no unnecessary excipients: no bulking agents, no anti-caking agents, no colorings. The vegetable glycerin provides a fluid texture and a naturally mild taste, with no added sugar and no mushroom flavor.
Origin of the raw materials
The reishi used in the Sleep. cure is grown in Normandy, in Terraphy's own laboratory. The brand controls the entire production chain: from cultivating the mushroom to bottling, everything happens on the same site, less than 100 meters apart.
The mushroom comes from EU certified organic farming. The passionflower and L-tryptophan come from EU organic farming according to the details shown on the product's official label.
Ultrasound extraction is carried out in-house, without chemical solvents, to preserve the mushroom's bioactive compounds in their entirety.
How to take Sleep.
The dosage recommended by Terraphy is 1 to 2 mL per day, i.e. 1 to 2 pipettes. It is taken in the evening, after dinner, 30 to 60 minutes before bedtime, held under the tongue for 30 seconds before swallowing for optimal sublingual absorption.
The dose can also be diluted in a drink without altering its taste or effectiveness. The bottle contains 30 doses based on 1 mL per day. Terraphy recommends a three-month cure for lasting effects.
The tinctures can be combined with one another with no risk of incompatibility, according to the information published on the official website. The Sleep. cure can, for example, be paired with the Stress cure for a more holistic approach.
Price and where to buy Sleep.
The Sleep. cure is available at €39.90 as a one-time purchase for a 30-dose bottle. The monthly subscription brings the same bottle to €29.93, with a 25% discount kept for life on the chosen cure.
Multi-bottle offers are also available:
- 2 bottles: reduced price compared with a single purchase
- 3 bottles: recommended offer for a full three-month cure
The product is available exclusively online, on the official Terraphy website. It is not available in pharmacies, drugstores or physical stores.
My take on Sleep.
The Sleep. cure stands out for the quality and clarity of its composition: 800 mg of organic Normandy reishi, 600 mg of passionflower and 220 mg of L-tryptophan per 2 mL, with no unnecessary excipients. The three actives complement each other coherently to support sleep onset and the quality of your nights.
The sublingual liquid format is a real advantage: it's quick to take in the evening, the taste is mild and pleasant, and there is no residual grogginess on waking according to the published information. I recommend this product for anyone looking for a natural alternative to conventional sleeping pills, fully made and traced in France.
