Radiance Tart Cherry Sleep provides pure Montmorency cherry concentrate, produced utilising the nutrient rich skin. A variety of sour cherry (Prunus cerasus), Montmorency cherry is one of the few known foods to naturally contain an appreciable amount of melatonin. Indeed, Tart cherry skins are the richest known source of naturally occurring substances that help support and maintain deep, healthy sleep. This extract is also naturally rich in antioxidant polyphenols, flavonoids and other naturally occurring synergistic nutrients.

The hormone melatonin, secreted by the pineal gland in the mid-brain, is involved in the control of the sleep wake cycle, or circadian rhythm. Melatonin secretion occurs primarily throughout the night, with onset of secretion temporarily related to a decrease in core body temperature causing an increase in sleepiness. Melatonin levels are at their highest during adolescence and begin to decline from the mid-20s. It has been proposed that the reduced amount of melatonin produced after this time correlates with the increased incidence of insomnia which occurs in middle aged and elderly people.

Sleep difficulties are all too common worldwide, with UK data reporting that well over one third of all people will experience trouble falling asleep or staying asleep on most nights. Many people who experience poor sleep report that it affects their ability to concentrate and perform daily activities and can make them feel anxious and blue. The usual orthodox treatment of for sleeplessness involves hypnotic drugs which can not only have the potential to induce dependence but can also induce daytime drowsiness; exactly what sleepless people are trying to avoid!

Radiance Tart Cherry Sleep provides 400mg of the high potency skin extract of Montmerancy Cherry. Research shows that supplementing with tart cherry supports healthy sleep patterns without the side effects of pharmaceutical sleeping aids. It is suggested that the interplay between the many beneficial phytonutrients within tart cherries may be responsible for its sleep supporting actions.

Tart cherries are also a great source of anthocyanin’s. These compounds support healthy inflammatory pathways in the body, while supporting healthy blood sugar and cholesterol levels.


For those with sleep difficulties, both trouble in getting to sleep and staying asleep. May also be of benefit for those people who may have disrupted circadian rhythms due to shift work, jet lag or being a new parent. Radiance Tart Cherry Sleep may also provide benefit for people who experience joint and muscle discomfort , are at risk for cardiovascular disease or just want to support ultimate health and vitality.

Very Good Review by

My husband has been taking Tart Cherry for a couple of years now. He says he still has trouble sleeping but I dont believe him because he always makes sure he takes his Tart Cherry at night. One awesome byproduct is that his snoring has decreased so there is two of us benefiting from this product!

First time for me Review by

This is the first time I have used Tart Cherry Sleep - and using it in conjunction with Magnesium capsules. Getting to sleep is the problem - usually when I do, I sleep very well. I am confident that I am now on the right track with this product

great stuff Review by

I was surprised how it worked so well from the first dose. I go to bed, take two tart cherry sleep capsules and read till I'm drowsy ( bout 40 minutes) .....then bang !! I'm out for the night !! Previously I'd lie awake for an hour or more. A very reliable sleep aid if it works for you, a pharmacist told me some are not so lucky but I recommend its worth the try.

Definitely works - but not immediately! Review by

I was disappointed after one week when I thought it wasn't working at all. However, I sought advice and was told to hang in as it can take up to 3 weeks to kick in - and it did! I bought it 18 months ago, took it for 4 weeks, and haven't needed any more since! Magic.

Tart cherry sleep works for me. Review by

I hadn't been having regular good sleeps even with using another otc sleep product. Have used Tart Cherry for over a month now and haven't got up at night because not getting to sleep for two weeks. This is brilliant as I am a person who needs sleep. I intend to continue using it. Thank you HealthPost!

Great results Review by

I had slept poorly since the earthquakes in 2010 and was getting about an hour to three hours sleep on average a night...the slightest thing woke me and I found it hard to go back to sleep. I started taking Radiance Tart Cherry capsules on recommendation and have found them really good...I fall asleep easily and stay asleep longer and sleep more deeply and if I do wake up I go straight back to sleep very happy and feeling a lot more human..!!

I have had interrupted sleep for the past 12 months. Magnesium helped a little but Tart Cherry has certainly helped more.

I followed the recommended dosage, 2 caps but it didn't seem to do much but when I increased it to 3 caps then I really start to get the full effect and my sleep has been significantly better since. Apart from having to take an increased dosage I'm very pleased with the results.

Tart Cherry has given me back my sleep. This product relaxes tight muscles and takes the edge off your pain. Review by

I am very impressed with Tart Cherry. I have hypermobility which causes pain throughout the body. I am usually woken by pain after only 1 & 1/2 hours to 2 hours sleep and have been for many years. My life has been on hold for a long time. Now with Tart Cherry I can take the worst edge off the pain and along with massage am getting between 5 - 7 hours sleep for the fist time in over 20 years.
