Melatonin is naturally produced by the pineal gland, following a circadian rhythm that rises as light fades, peaks mid-night, and tapers off toward morning. Production tends to decline with age, and screen exposure, night work and chronic stress can disrupt it at any age. Dynveo chose a 100% plant-based melatonin, extracted from the aerial parts of St. John’s Wort via a hydro-ethanolic process that preserves the molecule’s structure without harsh chemical solvents.

EFSA has authorised two health claims for melatonin: it contributes to a reduction in time to fall asleep (at 1mg before bedtime), and it contributes to the alleviation of the subjective feeling of jet lag (at 0.5mg before bedtime on the day of travel and the following days). At 1.9mg, this formula comfortably covers both thresholds. Melatonin binds to specific receptors in the hypothalamus, signalling the body to prepare for sleep: a slight drop in body temperature, reduced alertness, and a gradual transition into a sleep-ready state.

Take 1 capsule about 30–45 minutes before bedtime, with a glass of water, in a calm, dimly lit setting. Pair with good sleep hygiene: avoid screens for an hour before bed, keep the bedroom at 16–18°C, and keep regular hours.

For adults only. Not recommended for pregnant or breastfeeding women without prior medical advice. People with asthma, epilepsy, mood disorders, or taking psychotropic medication must consult their doctor before use. Do not exceed one capsule per day. Store in a cool, dry place away from direct light.

Plant-based vs. synthetic melatonin — what’s the difference?

Plant-based melatonin is extracted directly from a plant (here, St. John’s Wort) via a natural process; synthetic melatonin is made in a lab. Molecularly the two are identical — the difference lies in origin and manufacturing.

Can I take it every night?

It can be used daily over defined periods, such as during spells of difficulty falling asleep or jet lag. For extended use beyond a few weeks, consult a healthcare professional.

Does it cause morning grogginess?

At 1.9mg taken 30–45 minutes before bed, it generally does not cause residual morning drowsiness, thanks to melatonin’s short half-life (around 40 minutes).
