product information

The best Nootropic for sleep

Take ZZZZs before you hit the sack so you’re noticeably rejuvenated and refreshed in the morning.
Elle, April 2019

Every day starts with a good night’s sleep. ZZZZs naturally supports a regenerative sleep. Combining 5HTP with calming amino acids and the dietary minerals Magnesium and Zinc, ZZZZs supports quality sleep, naturally.

I have slept terribly for over ten years and have tried so many different products all of which have not worked. Saw these advertised and decided on one last try – they are brilliant. I no longer lie awake in bed sometimes till the early hours but within about an hour of taking the capsule drift off to sleep and manage to stay asleep most of the night. They have made such a difference to my quality of life.

5-HTP from Griffonia seed to help increase brain serotonin levels

5-HTP is the precursor to serotonin, the neurotransmitter responsible for happiness. Because of this role in creating serotonin, 5-HTP is also indirectly involved in producing melatonin, a hormone critical for sleep. Melatonin helps the body’s bio clock stay in sync and regulates daily sleep-wake cycles. Regular sleep-wake cycles are the foundation for restful and rejuvenating sleep. Research also suggests that 5-HTP may help shorten sleep onset time and increase sleep duration. Our 5-HTP is from Griffonia seed, a West African shrub1.

Calming Amino Acids L-Glycine and L-Theanine

We’ve included the calming Amino Acids L-Glycine and L-Theanine. L-Glycine has been shown to reduce sleep onset time and improve sleep quality while L-Theanine helps promote relaxation.2

Essential dietary minerals Magnesium and Zinc

Magnesium deficiencies are common in developed countries and a lack of magnesium can raise blood pressure and reduce insulin sensitivity. People with low magnesium levels often experience restless sleep, whereas healthy magnesium levels often lead to deeper, better sleep. Magnesium also plays a role in supporting sleep by maintaining levels of GABA, a neurotransmitter that promotes sleep.3

Zinc is an essential mineral and antioxidant involved in many enzyme processes. Recent research has shown that zinc levels vary with sleep quantity and zinc supplementation can increase both sleep amount and quality.4

BioPerine® to improve absorption

You aren’t what you eat, you are what you absorb, and much of the goodness from food and supplementation can be lost through poor nutrient absorption.

We ensure you get maximum benefits from ZZZZs with an effective dose of BioPerine®, an extract from black pepper proven to increase bioavailability (absorption of nutrients).

    Love these! I’m getting to sleep quicker and sleeping deeper since I started taking them – would definitely recommend for a good night’s sleep!

    • Thanks Jacq! Happy to hear the ZZZZs have been able to support your sleep.

    I have had chronic insomnia for 22 years. Believe me I have tried EVERYTHING! I have been on anti-depressants for most of that time for insomnia and tried many times to come off them but have never been able to do it as I would only average 2 hours sleep a night. With my doctors help I have been weaning myself off them for the last year and am now down to a really small dose but I could never quite come off them, until I tried these supplements. It took a few weeks but the effect is dramatic. I still wake in the night, but I find it easy to go back to sleep and I wake feeling refreshed! I am now of the medication and it feels amazing, at long last!

    • Thank you so much for taking the time to leave us a review Helen! We’re so glad that you’ve finally found something that could help improve the quality of your sleep!

    I have been using the nootropic ZZZZ’s now for nearly 2 months and the difference is amazing. It used to take me hours to fall to sleep, I really struggled. Now I always fall asleep within 20 minutes without fail after taking one of these. Because of this I have so much more energy in the day too! Would definitely recommend 😀

    • Thanks Kate for the detailed review. We’re so glad you’ve been enjoying the benefits of ZZZZs.

    I’m glad I held off writing a review for these. I’ve been taking them for almost 3 months now. Initially, the difference was immense and my review would definitely have said they’re life changing. However, recently I’ve been struggling beyond belief to wake up and it’s lasted all day. Feeling really groggy which has in turn made my mood quite low. I’ve trialled a few nights not taking them and while it wasn’t as easy to fall asleep, I feel so much better in the morning.
    Overall, I’d say they’re really useful if I’m going through a particularly difficult sleep period but for me (and maybe not be for everyone) ongoing use seems to have had some adverse effects.

    • Thank you for your detailed review and feedback Amy. We’re so sorry to hear about your experience with ZZZZs. Edge is the only supplement we recommend to take daily – Edge is like a multivitamin for your brain. Whereas Boost and ZZZZs are to be taken as needed. With many supplements even if it’s natural, it’s encouraged to review every 2-3 months or so just to see how you’re getting on with it and perhaps taking a break from it. As one possibility could be deficiencies of minerals could have been adjusted and corrected. Or some people can be/become sensitive to certain ingredients over time if taken daily. For some customers it might be a good idea to try to cycle the supplement. Please email us at [email protected] so we can assist you further.
