affron® Saffron

Why affron® Saffron?

affron® is a unique standardised Saffron extract that creates highly concentrated Saffron with long-lasting active stability. affron® is the world's first Saffron extract to be supported with peer-reviewed clinical evidence, demonstrating positive benefits to sleep quality and mood. affron® is also the most widely published Saffron extract on the market today, providing six studies to date, proving its effects for restorative sleep.

Saffron is an Indian Ayurvedic spice, which has been traditionally used in many Ayurvedic traditions for its calming and relaxing properties. Saffron has been used for more than 3,500 years and extends across many cultures, continents, and civilisations. This succulent spice has been shown to bring about a naturally calming effect and can help promote restful sleep. It has throughout history remained among the world's most expensive spice, known as ‘red gold’. Saffron contains two chemicals, crocin and crocetin, which researchers believe may help learning and memory function. Saffron is known as a ‘yogavahi’ herb in Ayurveda as it acts like a catalyst for other herbs taken alongside it. Saffron was also experimentally shown to be effective in relieving symptoms of premenstrual syndrome. 

Clinical Studies

  • In a study where affron® extract was given to healthy adults over 4 weeks in a double-blind, parallel, randomized, placebo controlled clinical trial. The study results shows that 28mg a day of affron® significantly decreased anxiety, stress, and depression (DASS) and significantly improved sleep quality (PSQI). These results indicate affron® to be a safe and effective ingredient to help support mood and sleep. 
  • Another 4-week randomized, double-blind, placebo-controlled study to examine the sleep-enhancing effects of 28mg/day affron® in 63 adults aged between 18 and 70 years (average age 50 years) with self-reported sleep problems. The study results showed a reduction in the Insomnia Severity Index, improvements in the Restorative Sleep Questionnaire Score, improvement in sleep quality (Pittsburgh Sleep Diary) and no significant adverse events were reported. affron® intake for 28 days at a dose of 14mg, twice daily was associated with greater improvements in sleep quality and restorative sleep compared to placebo.
  • In women 20–45 years of age, taking 30 mg of Saffron daily was more effective than a placebo at treating PMS symptoms, such as irritability, headaches, cravings, and pain 
  • In a eight-week study, taking a Saffron extract supplement helped significantly reduce appetite, body mass index (BMI), waist circumference, and total fat mass 

Tart Cherry

Why Tart Cherry?

The Montmorency Tart Cherry has become increasingly popular over the last couple of years. Yet, this fruit has served many people from all walks of life for centuries. The Tart Cherry is native to the Carpathian Basin, where it is a common wild and cultivated tree. Studies have shown that Montmorency cherries can improve sleep parameters such as duration and quality, due to its naturally high Melatonin levels. Melatonin often referred to as the ‘hormone of darkness’ is a neurohormone that is produced in our body and plays a fundamental role in regulating our sleep-wake cycle. Tart Cherries also contain Tryptophan, a precursor of Serotonin which has shown to reduce sleep latency in humans. As well as providing Melatonin, Tart Cherries have an impressive nutrient profile, containing high levels of antioxidant and anti-inflammatory flavonoids, which may be beneficial for physically active people, as they help to boost endurance sport performance, while also restoring the body. 

Clinical Studies

  • A placebo-controlled, balanced, crossover study with subjects >50 years of age and insomnia were randomized to placebo or cherry juice. The results showed that cherry juice increased sleep time and sleep efficiency. Cherry juice increased tryptophan availability, reduced inflammation and may be partially responsible for improvement in insomnia
  • In a randomised, double-blind, placebo-controlled, crossover design, 20 volunteers consumed either a placebo or tart cherry for 7 days. The results showed significant increase in Melatonin in the cherry group, whilst no differences were shown between baseline and placebo trials. There were significant increases in time in bed, total sleep time and sleep efficiency total with cherry supplementation. This data suggests that consumption tart cherry provides an increase in exogenous melatonin that is beneficial in improving sleep duration and quality in healthy men and women and might be of benefit in managing disturbed sleep.
  • In another study, runners given 16 ounces (480 ml) of cherry juice in the days leading up to and immediately following a marathon experienced less muscle damage, soreness and inflammation. They also recovered faster.
  • One group of men was given tart cherry supplements or a placebo in the days leading up to and immediately following an intense resistance training session. The tart cherry group lost up to 4% less muscle strength as a result of the training when compared to men given the placebo.
  • In one study, tart cherry juice reduced certain blood markers of inflammation in women with osteoarthritis, the most common type of arthritis.

Passionflower

Why Passionflower?

Passionflower has been used as a traditional herbal soother and sleep aid that benefits the treatment of sleep disturbance. The Native Americans had learnt from the Aztecs that the plant was used for its sleep inducing properties. The Passion flower began to be used as a herbal remedy in the second half of the last century and was introduced via American homoeopathy. Passionflower was used by the Eclectic Physicians to promote healthy sleep, especially when restlessness and interrupted sleep were extremely common. Passionflower appears to boost the level of 'GABA' in your brain. This compound lowers brain activity, which may help you relax and sleep better. 

Clinical Studies

  • In one double-blind, placebo-controlled study, 41 participants (18–35 years) drank a cup of tea made with Passionflower and wrote in a sleep diary for seven days and 10 of these participants underwent overnight polysomnography on the last night. Analyzing the sleep diary, sleep quality was significantly better in the tea-drinking group compared to the placebo group. This study shows that Passionflower has a potential effect on quality of sleep
  • Studies suggest that Passionflower works by increasing gamma-aminobutyric acid (GABA) in the brain. As a study where the potential mechanisms of Passion Flower were explored, showed that Passiflora extracts not only contain a high amount of GABA, but are also able to induce direct GABA.

Lavender

Why Lavender?

Once upon a time, Lavender was recommended for people suffering from insomnia or other sleep disorders. As people used to stuff their pillows with Lavender flowers to help them fall asleep and get a better night’s rest. In Asian traditional medicine, Lavender has long been used for its “cooling” effect and for relieving people from troubles in the mind. Lavender has been commonly used as an ancient remedy to induce relaxation and promote a good night's sleep.

Clinical Studies

  • Studies suggest that compounds in Lavender may stimulate activity in certain areas of the brain and influence the transmission of impulses between brain cells in ways that boost mood and produce a calming effect 
  • Another study on 79 college students who reported sleep issues showed that proper sleep hygiene and breathing in lavender improved sleep quality

Chamomile

Why Chamomile?

Chamomile has been a very popular herb since ancient times, native to Europe and Asia, it has been highly valued by the Egyptians, Romans, and Greeks for its medicinal properties. Nowadays, Chamomile is mostly known for its benefit as a sleep aid, as it is revered for its calming and soothing properties. In floral symbolism, Chamomile represents ‘may all your dreams and wishes be fulfilled’. It’s multi therapeutic, cosmetic, and nutritional values have been established through years of traditional and scientific use and research. The Egyptians even considered the plant sacred and believed it was a gift from the God of the Sun.

Clinical Studies

  • In one study, postpartum women who drank chamomile tea for two weeks reported better sleep quality compared to a group that did not drink chamomile tea. They also had fewer symptoms of depression, which is often linked with sleeping problems
  • Additionally, one study of 537 people observed that those who drank chamomile tea 2–6 times per week were significantly less likely to develop thyroid cancer than those who did not drink chamomile tea
  • In one study of 64 diabetic people, those who consumed chamomile tea daily with meals for eight weeks had significantly lower average blood sugar levels than those who consumed water
