Scrolling through your phone at 2 a.m., tossing and turning even though you’re desperate to fall asleep, waking up feeling just as tired as when you went to bed—does this sound familiar? The high pressure of modern life is pushing adults to the brink of sleep deprivation.
Data from Gallup in 2023 is striking: 73% of American adults sleep less than 8 hours every night, and 20% get no more than 4 hours of sleep. These two figures have surged by 10.6% and 42.9% respectively compared to a decade ago.
This has triggered a boom in the sleep-aid market, which reached a global size of $6.8 billion in 2023 and is projected to hit $11.8 billion by 2034.
However, melatonin, the mainstream solution, has long been hiding potential risks. It accounts for 35.8% of the sleep supplement market, yet 40% of users report dizziness and grogginess the next day, according to a 2022 report by Nutritional Outlook. No wonder 82% of consumers are now turning to safer, natural sleep-aid ingredients.
SIVI, developed by Chilean ingredient supplier Select Ingredients, is filling this gap perfectly. Derived from Passiflora incarnata—also known as passion flower—this melatonin-free extract is packed with high levels of GABA and over 5% vitexin, the two key natural compounds for better sleep.
Passion flower is no new kid on the block. First discovered by Spanish explorers in 1529, it has long been a staple in Western herbal medicine. Today, it is cultivated across Europe, America and Asia, boasting both ornamental and medicinal value. While it has been introduced in China’s Jiangsu, Guangdong and other regions, it is currently mostly used in cosmetics, with its sleep-enhancing potential only just starting to be unlocked.
The efficacy of SIVI is far from empty talk. Select Ingredients, in collaboration with the Pune Ayurved College, published a randomized, double-blind, placebo-controlled study in the Cureus journal, which validated its effects using real data from 65 insomniac participants.
In the experiment, 32 subjects took 600mg SIVI capsules daily before bed, while 33 others received placebo capsules. After 30 consecutive days:
Stress levels decreased by 27.67%, with anxiety significantly relieved;
Sleep duration increased by 13.33%, putting an end to tossing and turning all night;
The PSQI score—a key indicator of sleep quality—dropped from 14.72 to 9.00, representing a 40% improvement;
No side effects were observed throughout the trial, with participants’ pulse, liver and kidney function all remaining within normal ranges.
The key lies in its dual regulatory effect on the GABAergic system:
A Natural Source of GABA: GABA acts as the brain’s “relaxation signal”. Passion flower extract ranks first in GABA content among 21 common plants, clocking in at 629mg per 100g, which directly reduces neuronal excitability.
Vitexin’s Potentiating Effect: As a core flavonoid component, vitexin activates GABA receptors to extend their “working hours”. It also regulates mood-related neurotransmitters, alleviating stress-induced insomnia at its source.
Beyond improving sleep quality, the raw material of SIVI has been included in pharmacopoeias across multiple countries, boasting versatile benefits. It aids in alleviating drug addiction, relieves menopausal symptoms, and even delivers analgesic effects by activating GABA and opioid receptors, truly earning its reputation as a natural all-rounder.
While melatonin’s side effects have turned many users away, this passion flower-derived natural ingredient is redefining sleep support with scientific evidence. For anyone struggling with insomnia, or developers focused on natural health solutions, SIVI is a choice well worth considering.
