Experiencing a restless night filled with tossing and turning and limited snooze time can leave us feeling dreadful the next day. And those who get this on a regular basis know all too well the importance of a good kip.
Sleep is crucial for recovery, boosting and supporting the immune system, heart health, cognitive function and more - and many of us aren't getting enough of it. Those battling with sleep issues have likely explored the various sleep supplements available, but it's not always clear which are effective and which are essentially overpriced chewy sweets.
Shoppers who have had problems with restless nights have sung the praises of Protein Works' Sleep Deep supplement, which is currently on sale for £11.99, reduced from £19.99. The science-backed formula claims to aid in achieving some much-needed shut-eye - and shoppers have said it has helped them get their 'best' night's sleep.
The supplements contain calming plant extracts such as lemon balm, lavender, and chamomile, along with essential minerals like magnesium to help alleviate fatigue and the dreaded brain fog the following day. The key ingredient, however, is L-Tryptophan, an amino acid that assists in the synthesis of serotonin, the 'feel good chemical' in the brain, as well as melatonin, the hormone that signals to the body when it's time to sleep, reports the Liverpool Echo.
Speaking about the sleep supplement, Kyle Crowley, Chief Product Officer at Protein Works, explained: "We designed Sleep Deep around the real science of sleep. It's not just to help people fall asleep faster, but to support the deeper sleep stages that truly restore your body and brain.
"One of the key ingredients is L-Tryptophan, which helps the body produce serotonin and melatonin. These are both essential for sleep quality and mood regulation.
"This isn't just about sleep. It's about how well you live during the day. Deep, uninterrupted sleep supports a healthy metabolism, sharper thinking, improved memory, and better appetite control, which is why many users report benefits like improved mood and weight management over time."
For those keen on exploring their options when it comes to sleep supplements, You're Looking Well Night Pill, priced at £32.50 for a 30-day supply, is available from SpaceNK. This supplement boasts ingredients such as magnesium bisglycinate and L-theanine to aid in relaxing the body, hastening the process of falling asleep, and ensuring sound sleep throughout the night.
Alternatively, there's the Novomins Night-Time 60 Gummies, which can be bought for £19.99 at Holland and Barrett. These chewable gummies come with an array of beneficial additions including magnesium, vitamin B12, L-Theanine, and others
Protein Works' sleep supplement has garnered numerous positive reviews. One person raved: "As a shift worker, my sleep routine is awful. Since purchasing these, I can genuinely say that they have given me the best night's sleep. They have literally saved me for countless sleepless nights."
Someone else added: "I started taking Sleep Deep capsules just over a week ago. I've noticed a huge improvement from the first morning waking up that I feel so much more refreshed than I used to.
"I don't wake during the night and I don't feel like I have brain fog anymore during the day. I feel like I have a lot more clarity. I also haven't had my usual insomnia since taking them"
Another reviewer shared their success with the supplement and said: "These have made a huge difference to my sleep routine! I used to be awful at getting up at 7am! Now I'm waking before my alarm!" "Made an instant difference," said another user, who wrote: "relaxes me and helps me drift off."
While many people are calling this particular supplement a 'game changer', over on Trustpilot, some buyers haven't been too pleased with their experience regarding the delivery. One customer remarked: "My order was lost by the delivery people," although they added: "Protein Works sorted it quickly and very easily! Very happy with the customer service!" Another commented on the pace of delivery: "Delivery slower than I'd expect."
