    Knock out — 5x good nights

    Sleep better with Knock out

    Do you sleep badly and think you have used everything? Maybe you’ve tried melatoninvalerian root5-HTP, or unhealthy sleeping pills like oxazepam or diazepam

    More and more clients are using the Knock out Sleeping Aid in addition to our Ultima Bio. We regularly hear how surprised customers are at the effect, after years of bad sleep. User experiences are almost always positive, which is also evident from the many repeat orders that are placed.

    Because of strict regulations, SleepBD is not allowed to say anything about the efficacy of GABA.



    Vegetable glycerine, gaba, sodium bicarbonate, magnesium and water.


    Why order from SleepBD

    • Quick and personal contact for questions.
    • Honest advice, if we think a product is not right for you we will definitely tell you.
    • You support the continued sharing of free tips and information on sleep.
    • Apart from the products, we provide tips on your personal situation.


    How to use it?

    Other than addictive and unhealthy sleep medications…

    1. Take a bottle 7 hours before your normal bedtime.
    2. Because of the late onset it takes 2-4 hours, which is good because you get sleepy and tired in a slow but very nice way.
    3. Never take more than 2 bottles.
    4. After 3 days of use, pause for at least one day. This way you will not build up a tolerance and the minimum dose will always be effective.


    Recommended usage

    80% of clients use Knock Out on average two to three times a week. When the stress gets too high when you need a good night’s sleep before the next (important) day, think of performing at work, needing focus or an important test. But also when there is a nice weekend coming up when you want to be rested.

    Daily use? We do not recommend this. It is possible to use it for 3 days in a row, then pause one day. That way the minimum dose always remains effective.



    Never take more than two bottles at a time. Do not exceed recommended dosage. A healthy lifestyle is important. A dietary supplement is no substitute for a varied diet. This dietary supplement is not suitable for children. Preferably not to be used during pregnancy and lactation.


    Side effects

    Knockout is generally well tolerated by adults. However, there are always (as with paracetamol) possible side effects. The possible side effects are:

    Burning throat

    Are you taking medication? Then it is possible that these have an effect on the GABA system or interact with Knock out as a supplement. If you are taking one of the following medications, please contact your doctor before using Knock out to get better sleep:

    High blood pressure medication. GABA can lower your blood pressure. If you take it in combination with other blood pressure medications, your blood pressure may drop too low.
    Antidepressants. These medications can affect the GABA system.
    Medication that affects brain activity.


    Storage advice

    In the refrigerator, between 3-7 degrees. Keep out of reach of young children.



    Content: 5 bottles
    Taste: Sweet/sour

    🇺🇸 Great against stress and for sleep

    I bought the Knock Out Edition because I suffer from very severe sleep problems. But since I also work, these sleep disorders are very stressful for me. I take a vial of Knock Out Edition at 4 p.m. so I can sleep through then. I recommend taking it only when you don't have to drive anymore, because it quickly creates a light foggy feeling in your head! But then when I go to bed around 10 p.m., I can sleep normally! In the morning I slept well and I no longer notice that I am in a daze. I take it 2 times a week if I have had a bad night's sleep before, or know that the coming night may be difficult! The taste takes some getting used to, but that's not a problem. They are easily accessible by phone, very friendly and really try to give you good and comprehensive advice! I am very happy with it and would recommend it to anyone dealing with worse sleep disorders.

    🇺🇸 Very calming

    I have been using Knock out for a few months now and am super happy with the effect. I am currently going through a difficult period. I suffer from a lot of stress and do not sleep well. Knockout helps me get more peace of mind, which automatically makes me sleep better. I would recommend it to anyone.

    🇺🇸 It works, no side effects BUT pricey

    My mother uses it when she is stressed and really needs a night's sleep. T works for her every time. She doesn't even have to get out for a toilet visit. Usually 2 or 3 times.

    Irene W.
    🇺🇸 Really works!

    It really works. So nice to take occasionally when you want a good night's sleep.
    Will definitely keep using this!!

    🇺🇸 Excellent product!

    Excellent customer service. I can really recommend the knock-out edition, but also the lavendel CBD patches.



    CBD is the abbreviation for cannabidiol. One of over 100+ naturally occurring cannabinoid compounds found in Marijuana and Hemp.

    You’re probably familiar with THC, which is the most famous compounds found in Marijuana.

    However, as the second most prevalent cannabinoid in Marijuana and the top non-psychoactive cannabinoid found in hemp, CBD has been gaining much attention in the scientific community and media because of its health benefits. 

    Unlike THC, CBD is not psychoactive. In other words, it’s not what gets you a high or stoned feeling.

    Source 1.

    Short and simple, no.

    Studies have shown that even high does of CBD do not cause a high or stoned feeling.

    All of our hemp extract products are made from industrial hemp with THC levels below 0.05%. There is no intoxicating effect from taking our products.

    Yes, driving is still safe. CBD doesn't effect your reaction time.

    A studie shows that after ingestion there was no expected reduction in the reaction time in most test subjects.

    In view of this conclusion we cannot recommend this product as a suitable means for achieving faster or slower responses to a visual stimulus which could then be used in various sports or in driving.

    Because each person is unique, it is difficult to set a predetermined measurement that is perfect for everyone.

    To find out what the right dose of CBD is, you simply have to start taking it.

    Luckily, CBD is completely safe and will never cause dangerous or unwanted effects when ‘overdosed’. But logically and economically speaking, there’s no need to consume more than necessary.

    The start dosage depends on the chosen product. We always advice to start with the minimum dosage stated on the label. This provides the minimum amount of CBD necessary to experience the magical effects of CBD.

    Like with any substance, you can take more CBD than your body can handle. Studies show doses up to 1,500 milligrams a day have been well-tolerated, but every person is different.


    When you take a medication or other substance, your body has to metabolize it, or break it down. Drug metabolism happens throughout the body, such as in the gut, but the liver does a big part of the job, too.

    A family of enzymes called cytochrome P450 (CYP450)Trusted Source does the important work of converting foreign substances so they can easily be eliminated from the body.

    But some medications or substances affect CYP450, either by slowing or speeding up drug metabolism. That change in metabolism rate can alter how your body processes the medications or supplements you take — hence a drug interaction.

    The CYP450 family of enzymes is responsible for metabolizing several cannabinoids, including CBD, research shows. Specifically, CYP3A4, an important enzyme within the CYP450 family, does the task. But during this process, CBD also interferes with CYP3A4.

    The CYP3A4 enzyme is in charge of metabolizing about 60 percent of clinically prescribed medications. But if CBD is inhibiting CYP3A4, it can’t work as effectively to break down the medications in your system.

    The reverse can happen, too. Many medications inhibit CYP3A4. If you then take CBD while on these medications, your body can’t work to process the CBD as effectively.

    If your body is metabolizing a medication too slowly, you may have more medication in your system at one time than intended — even if you’ve stuck to your normal dose. An increased level of a medication in your system could exaggerate its effects, including unwanted or harmful side effects.

    Some substances also speed up the work of the CYP450 enzyme family. If your body is metabolizing a medication too fast because another substance is inducing the enzymes, you may not have enough of the medication in your system at one time to treat a health issue.

    If you want to try CBD as an add-on therapy to ease symptoms of a certain condition, talk to your doctor about it first.

    Although our products comply with the federally mandated THC limit of 0.05% THC by dry weight, there is a small change it will show up, however this does mean a positive test is possible.

    Drug tests are not uniform, and the THC threshold that would yield a positive result is stricter in some tests than others.
