What does Zenbev do?

Zenbev is a delicious beverage mix of organic ingredients that provides a natural source of tryptophan derived from pumpkin seeds. As a precursor to serotonin and melatonin, tryptophan enhances mood, emotion and sleep.

Zenbev can be taken during the day to provide a powerful source of tryptophan, a precursor for serotonin. Serotonin regulates mood, emotion and appetite, and is well-known to alleviate stress, anxiety and depression. Other purported benefits of ingesting a natural source of tryptophan include easing chronic pain symptoms, weight loss and increased libido.

Tryptophan is light sensitive, meaning it metabolizes differently in light vs. dark conditions. When taken during daylight hours Zenbev’s tryptophan becomes serotonin providing the afore mentioned benefits. If taken at night, Zenbev’s tryptophan turns into serotonin, which then metabolizes into melatonin, thus activating the brain’s own sleep mechanism. As the brain produces the exact amount of melatonin that it requires, the body is primed for a natural, restful sleep.

Zenbev vs. Sleep Medications

Virtually every sleep medication, either herbal or pharmaceutical, disrupts sleep architecture. Medications currently available tend to increase light sleep (stages 1 and 2) at the expense of deep sleep (stages 3 and 4) as well as inhibiting REM sleep which results in side effects of drowsiness and lack of refreshment. As the tryptophan in Zenbev allows the brain to produce melatonin, none of the sleep stages are compromised, resulting in a preservation of sleep architecture and a deep, uninterrupted sleep.

Zenbev vs. Anxiety Medications

Medications to reduce anxiety are most often from a class of drugs known as benzodiazepines; this family of drugs is associated with tolerance and dependence. Benzodiazepines are synthetic and do not work within the body’s own natural chemistry and as such can have significant side effects such as excessive sedation and lack of coordination. Zenbev, on the other hand, provides a natural source tryptophan which bolsters the body’s own natural anxiety management system.

Zenbev vs. Synthetic Melatonin

Since the melatonin produced in our brains is responsible for the onset of sleep, many people try to take synthetically-produced melatonin. Over-the-counter melatonin should not be considered natural. One of the issues with synthetic melatonin is the short half-life in the body. The half-life should be measured in several hours. Synthetic melatonin leaves the body quite rapidly with a half-life of less than one hour which means the effect is lost midway during the night. Consequently, a higher dosage is required, resulting in a hangover effect the next day.

Although melatonin is thought to be ‘natural’, when used in high dosages it overrides the brain’s natural sleep chemistry by providing too much of the end product. The brain loses its chance to regulate the production of this important sleep hormone. More importantly, the body does not have an opportunity to suppress production of melatonin when sleep is coming to the end. The brain has evolved an elaborate process of producing and regulating melatonin so that just the right amount is used in just the right area of the brain.

It may seem convenient to circumvent the process and provide super dosages of melatonin to the body to produce sleep, but it ignores normal sleep physiology resulting in increased difficulties which are not necessary. Zenbev provides the ingredients and circumstances in order for the brain to determine when and how much melatonin is needed, resulting in a good night’s sleep.

Zenbev vs. 5-HTP

Supplemental 5-HTP is the intermediary between tryptophan and serotonin and has been offered as a natural remedy for serotonin deficiency-related medical states. Natural source tryptophan, however, offers a major advantage over 5-HTP in that it is not directly metabolized to serotonin in the intestine which protects against side effects associated with 5-HTP such as increased nausea, vomiting, cramping, constipation and/ or diarrhea. 

Frequently Asked Questions

Is there a risk of becoming dependent on Zenbev to fall asleep?

No. Almost all sleep drugs are associated with either dependence (the need to continue with the medication or the experience of “rebound” insomnia when it is discontinued) or tolerance (requiring an increased dosage to maintain the same effect) because these drugs override the brain’s natural sleep chemistry. Zenbev does not cause dependence or tolerance because it works with the brain’s natural sleep chemistry. It is the brain that decides how much is required and when. As a result the normal brain chemistry is maintained.

What is it in Zenbev that makes it work?

Zenbev is a natural source of tryptophan, the amino acid found in milk and turkey. Once in the brain, tryptophan becomes serotonin and, in turn, melatonin. This conversion to melatonin from tryptophan is light-sensitive. That is to say, tryptophan only becomes melatonin if it is dark; otherwise it remains as serotonin, a chemical that helps you to relax but does not make you fall asleep. Therefore, if taken during the day, Zenbev helps alleviate anxiety, depression and other stress-related clinical states. If taken at night, Zenbev is a powerful ally against insomnia. Zenbev is specially formulated with all-natural ingredients that have several advantages over synthetic derivatives such as prescription tryptophan or over-the-counter (OTC) 5-HTP or melatonin. These drug equivalents can produce much more serotonin or melatonin than the brain needs. When there is an over-production, side effects such as daytime sleepiness can occur.

Isn’t tryptophan banned by the FDA, and can it be taken safely?

Tryptophan is an essential amino acid, meaning that the body cannot produce it and must ingest it through a food source. Our bodies require tryptophan as the precursor to serotonin, a hormone that regulates sleep, mood and appetite. 15-years ago, pharmaceutical-grade tryptophan was banned by the FDA due to the contamination of a batch synthetically sourced from genetically modifying a bacterium. This process was discontinued and synthetic tryptophan has remained available by prescription in Canada. Zenbev, however, is comprised of a natural source of tryptophan derived from organic pumpkin seeds, and formulated to be easily assimilated by the body. According to Health Canada, amino acids present in a protein configuration are not considered to be drugs; and therefore would not be considered to be subject to special measures as per the DIN (Drug Identification Number) Enforcement Directive and the Therapeutic Products Compliance Guide.

Is Zenbev a drug?

No. It is an all natural food made from organic pumpkin seeds, dextrose and rice starch.

How much tryptophan is in a serving of Zenbev?

The amount of tryptophan ingested depends on the amount of Zenbev required. We recommend starting at 1-tablespoon and increasing the dosage as necessary. Most clients report that 1-2 tablespoons is sufficient. One should be aware that at more then 4-tablespoons, the dosage of tryptophan can be greater than 250 mg. This should be more than adequate for most clients since the inventive formulation of Zenbev allows the body to utilize the protein source of tryptophan very efficiently.

What are high glycemic index foods?

Recent fad diets have claimed that eating too many carbohydrates can lead to high insulin levels, resulting in health issues such as obesity and diabetes. Foods that score higher than 70 on the glycemic index (ie. potatoes, parsnips and donuts) are high GI foods, the reference food being pure glucose or white sugar at 100. High GI foods provide bursts of energy that may be followed quickly by blood sugar reductions and hunger. If taken in moderation, some high GI foods can be beneficial and should not be avoided altogether. However, overly processed foods containing excess sugar should be limited. We can make an effort to become aware of the glycemic reaction that certain foods cause and therefore make better-balanced food choices.

Zenbev’s special formula includes a small amount of organic dextrose, a high GI food that serves the specific function of binding to all the amino acids in the protein chain except for tryptophan and shunting them away. Tryptophan is then allowed efficient access across the blood brain barrier (BBB), thus contributing to Zenbev’s effectiveness. Diabetics should be cautious when taking Zenbev and refer to the nutritional panel on the label.

Does Zenbev have side effects?

It takes about thirty minutes for circulating melatonin to become inactive after the sun rises or lights are turned on. During that time there may be drowsiness which subsides and does not interfere with daytime functioning.

Zenbev contains organic dextrose. Diabetics taking Zenbev should be aware that 2 tablespoons contains the same amount of carbohydrate as one slice of dry toast.

Finally, patients taking drugs that already cause drowsiness, such as antidepressants (pharmaceutical grade or natural such a St. John’s Wort) or lithium, should avoid Zenbev.

Will It Knock Me Out?

No. Zenbev does not override the brain’s own natural sleep chemistry; it allows the brain to produce as much or as little melatonin as it needs. As noted above, melatonin takes approximately ½ hour to leave the body after first light, so there may be a hold-over sleepiness of about that amount of time.

How does Zenbev compare to other drugs for treating insomnia?

Zenbev is the only sleep aid that works within the brain’s own natural sleep chemistry. It allows the body to produce melatonin but does not override the natural sleep chemistry as melatonin itself might. It also enhances the 5-stages of sleep whereas other sleep aids including prescription drugs and OTC antihistamines actually suppress deep sleep (stages 3&4) as well as REM (dream) sleep.

Can I use Zenbev every day or night?

Yes, but it may not be necessary since there is a positive effect for a few days after one stops Zenbev. The best rule of thumb is that it takes a few doses before its optimal benefit is seen and it continues to work for a few days/ nights after it was last taken. One way of optimizing this benefit is to take Zenbev for 5-7 days/ nights and then stop it for 2-3 days/ nights. If you prefer to take it every day, however, there is no difficulty with that approach.

Does it need to be refrigerated?

No. Zenbev should be stored in a dry cool space. Zenbev is made from ingredients that are stable, with an expected shelf-life of several years.

How long will a jar last?

One jar should last about 30-days, assuming a dosage of two-tablespoons per day. It may last longer if taken on an intermittent schedule or at a lower dosage. It will not last 30-days if taken at a higher dosage on a daily schedule.

What if it doesn’t work?

It takes anywhere from three days/nights to one week to notice the effects so it is important to persevere and give Zenbev a good long trial. If you get to the end of the jar and are feeling that it is not helping you or if you are unsatisfied with Zenbev for any reason, please return it to the place where you purchased it, with your receipt, for a full refund. If you have any questions about Zenbev as you are taking it feel free to email us at

Can Zenbev help all sleep or anxiety problems?

No. Zenbev is effective for the vast majority of people suffering from insomnia and/or those who feel stressed but will not work for a small number of people who may suffer from disorders such as sleep apnea or restless leg syndrome. Again, Dr. Hudson can help clarify the differences between insomnia and serious sleep disorders. You may contact him at

Zenbev is highly effective for stress-related problems such as anxiety and depression if resulting from a lack of serotonin. Zenbev is specially formulated to deliver tryptophan, which is the precursor for serotonin, in a way that can be easily assimilated by the body. Those with long-term cases of depression should also consult a medical professional.

Who should avoid taking Zenbev?

Those who plan to drive or operate heavy machinery at night should not take Zenbev before doing so. If you are pregnant or nursing a child, you should consult your physician. Those taking antidepressants, including St. John’s Wort and/or lithium should not take Zenbev. If you are diabetic as mentioned earlier, please consult the nutritional panel and your doctor.

It's a good product and helps me sleep so I can't complain there... However, the packaging is a fail! The bag will not seal once opened. So now I'll need to transfer the powder from this bag, to my 250g Zenveb container and put a clip on the rest. This is NOT an inexpensive product, please change the packaging!"

  • 8/10  Great way to learn to sleep deeply again.

    By Paul Neumann on Tuesday, June 10, 2014 03:39 AM

    Effectiveness: 8/10

    (+) First Dose Results,Tastes Great,Great packaging!
    (-)  Mixes Poorly

    How did you use it?:Before Bed

    "My good friend Kathleen suggested that I try Zenbev when she heard about my struggle with sleep. I had just completed trials of two other products and was feeling a bit frustrated. Each product was costing me in excess of $40.00. After a little research I ordered Zenbev. It worked the first night perfectly as described. I slept deeply and I returned to sleep after my initial waking. The product continued to work for the next week or so equally well. I decided to stop the product and realized that I continued to get great sleep. Just once I took it again because I feared I might not sleep well and I noticed extreme dry mouth in the morning. I don't think I really needed it. Now I sleep perfectly without it. My belief is that Zenbev is a sleep aid. Like a band aid you use it when the problem is bad and needs help healing. Then you remove the band aid and let nature take it's course."

  • 7.9/10  Helped Stabilize My Sleep

    By Andrew Butters on Tuesday, May 20, 2014 08:38 AM

    Effectiveness: 8/10

    (+) Stabilized my sleep
    (-)  Mixes Poorly,Doesn't taste terrible, but sure as heck doesn't taste like chocolate

    How did you use it?:Everyday,Before Bed

    "I've been a chronic insomniac for going on five years now. Two separate sleep studies, a 6 week "sleep class" at the university, and a veritable pharmacy of drugs to help me visit the land of nod left me nothing but tired, irritable and zombie like. Then I tried ZenBev. It took about a week and then the effects were quite noticeable. One thing that I noticed was that I was not getting any more sleep, nor was I falling asleep more quickly. I've trained myself to fall asleep in short order but staying asleep and getting my share of all the sleep stages was the problem (Stage 1 through 4, plus REM). With ZenBev I started dreaming again (REM) and am not walking around in a daze every afternoon at work (getting the restorative Stage 4). If sleep stabilization is your problem then I'd recommend ZenBev in a heartbeat."

Suggested Use

Zenbev Recommended Use or Purpose: To promote sleep. To relive the symptoms of insomnia. Dosage form: powder for solution, to be taken orally.

Zenbev should be taken at night to promote restful sleep. Start with 1 scoop per day for the first 3 days. If the desired effect is reached then continue with a 1 scoop serving. If the desired effects are not reached then increase by 1/2 a scoop every 2-3 nights (to a maximum of 5-6 scoops) until desired effect is reached. 

Mix in water or juice.

1 scoop contains 10g of powder. Each scoop contains 45 mg of tryptophan.

For help with insomnia: Take Zenbev approximately 20-30 minutes prior to turning off the lights. If you take it an hour before you turn off the lights the effectiveness of the product will be severly reduced. Start with one full scoop until desired effect is reached. May take up to a week to notice effects.

Zenbev can also be cycled such as using it for 5 days on, 2 days off. For the off days you will still have the residing effect from consistent use of the 5 days prior.

Note: this product does not dissolve in liquids. May be used for one week. Consult a health care practitioner for use beyond one week. May be taken with applesauce, jam or yogurt if avoiding fluids before bed.

If you use the product fully based on the recommendations listed and feel you aren't getting the desired results please email and Dr. Hudson can offer more targeted support.
