Do Pistachios Contain Natural Melatonin? How a 3mg Dual-Action Formula Supports Sleep and Body-Clock Rhythm

Product focus: Hong Kong’s first natural pistachio melatonin formula — drug-free.*
Life in Hong Kong moves quickly. You may feel physically tired while your mind remains active after getting into bed. As more people explore natural bedtime nutrition, one practical question stands out: Do pistachios really contain natural melatonin?
The short answer is yes. Researchers have detected naturally occurring melatonin in pistachios, and some cultivars and specific Pistacia vera extracts have shown noteworthy levels. CATALO uses a standardised formula that clearly states 3mg natural melatonin per capsule, together with natural pistachio extract and marine magnesium, making the ingredients and serving amount transparent. 1
Why Do Pistachios Contain Natural Melatonin?
Melatonin is not exclusive to the human body. Some plants also produce melatonin as part of their biological response to daily cycles and environmental stress. Pistachio (Pistacia vera) is one plant food in which melatonin has been measured.
A 2019 study in the Journal of Food Composition and Analysis used LC–MS/MS to analyse almonds and pistachios from different sources. Across the samples studied, pistachios contained more melatonin on average than almonds, while one pistachio cultivar exceeded 12,000 pg/g. The researchers also reported substantial variation between cultivars and suppliers.1
A separate 2023 study screened 25 commercial plant extracts. A specific dried Pistacia vera fruit extract contained a high level of endogenous melatonin and produced pronounced signalling activity in cells expressing human MT1 and MT2 melatonin receptors. The researchers also observed an additional, unidentified component that appeared to potentiate melatonin signalling in the cellular model.2
3mg Natural Pistachio Melatonin × Marine Magnesium: What Are the Product Benefits?
CATALO Natural Dual Fast Sleep Melatonin combines 3mg natural melatonin, Melostacio™ natural pistachio extract and Aquamin™ natural marine magnesium powder. The official product profile highlights four practical benefits:
| Product benefit | Formula focus |
|---|---|
| Helps you fall asleep faster | Each capsule provides 3mg natural melatonin and is taken approximately 30 minutes before bedtime to support the body’s preparation for sleep |
| Supports body-clock regulation | Melatonin participates in the timing signal associated with sleep and wakefulness, making the formula relevant for busy adults with irregular routines |
| Promotes deeper sleep | The dual-action formula combines natural melatonin with marine magnesium; the official product profile identifies improved sleep quality as a key benefit |
| Relaxation and fewer dream-related awakenings | Aquamin™ natural marine magnesium powder supplies 100mg natural magnesium; magnesium is an essential mineral needed for normal nerve and muscle function |
Is Eating Pistachios the Same as Taking 3mg Melatonin?
No. The naturally occurring melatonin in a food can vary by cultivar, batch and processing. A consumer cannot reliably calculate an exact melatonin intake from one serving of ordinary pistachios. The concentrated pistachio extract used in a study is also not equivalent to eating the whole nut.
A standardised supplement differs because it can state the amount supplied per serving, the intended directions and the other formula ingredients. This does not replace good sleep habits; it simply makes the intake more transparent.
Hong Kong’s First Natural Pistachio Melatonin Formula — Drug-Free*
CATALO Natural Dual Fast Sleep Melatonin is positioned as Hong Kong’s first natural pistachio melatonin formula — drug-free. Each capsule clearly states three formula components:
| Formula component | Amount per capsule | Role in the formula |
|---|---|---|
| Natural melatonin | 3mg | Supports the timing signal associated with the sleep–wake rhythm |
| Melostacio™ natural pistachio extract | 100mg | Provides a clearly identified natural pistachio-source component |
| Aquamin™ natural marine magnesium powder | 319mg | Provides 100mg natural magnesium; magnesium is an essential mineral needed for normal nerve and muscle function, as described in the NIH magnesium fact sheet |
“Natural source” describes ingredient origin. “Drug-free” describes the product’s positioning as a nutritional supplement rather than a prescription sleeping medicine. Neither statement means that the formula has no physiological effect or guarantees immediate sleep.
When Should You Take 3mg Natural Melatonin?
Each individually packed CATALO Natural Dual Fast Sleep Melatonin vegetarian capsule provides 3mg natural melatonin. The official direction for adults is one capsule once daily, approximately 30 minutes before bedtime. Do not increase the amount independently because one night feels more difficult.
According to the NCCIH melatonin guidance, melatonin participates in the timing signal associated with sleep and wakefulness. It is better understood as helping the body recognise when it is time to prepare for sleep rather than forcing unconsciousness. A regular time to stop working, dimmer light and less screen exposure before bed remain important parts of an evening routine.
