What You Need To Know About Zhou Nutrition Driftoff

Insomnia is a common but serious issue for many people so this supplement will seem like a lifeline, especially if you are suffering from insomnia on a regular basis. It looks like it works for many people, and it does contain a blend of ingredients which are known to promote sleep and relaxation. However, Driftoff will cause side effects and adverse reactions in many users, so you may find that it makes your sleep patterns worse. Zhou Nutritiondoes offer a money-back guarantee, and some Amazon customers have been refunded because they were not satisfied with this supplement.

What Are The Side Effects Of Zhou Nutrition Driftoff?

Potential side effects may include skin rash, anxiety, bad dreams, wired feeling, insomnia, increased heart rate, restlessness, dizziness, headaches, heartburn, stomach pain, gas, vomiting, diarrhoea, light headedness, muscle weakness, sexual problems, increased heart rate, spaced out feeling, and decreased blood pressure.

Tryptophan supplements are also linked to a neurological disorder called Eosinophilia–myalgia syndrome (EMS).

How Much Does Zhou Nutrition Driftoff Cost?

Driftoff is not overly expensive. If you buy direct from the Zhou Nutrition website one bottle of 60 capsules (30 servings) costs $21.04.

Shipping is calculated at the point of sale and Zhou Nutrition are happy to ship to many countries outside the USA including Australia, the UK, and Europe.

If you sign up to the “subscribe and save “option the price is reduced to $19.99 and includes free shipping. We do not advise this option as auto ship agreements can be difficult to cancel.

You can also buy Driftoff via Amazon USA where it costs $21.04 per bottle of 60 capsules (30 servings). If you have Amazon Prime, shipping is free.

Our Verdict On Zhou Nutrition Driftoff

The problem with Driftoff is one of safety. This supplement does seem to work for many people and there is a lot of genuine positive feedback but the big issue lies in the side effects. Many customers have reported a long list of unpleasant reactions to this supplement, including bad dreams and increased heart rate and anxiety levels, and in our opinion there are just too many of these to be ignored.

The good news is that Zhou Nutrition does offer a 60-day money-back guarantee, and some Amazon customers have been pleased with this good customer service. And of course it does mean that you can try risk free. But we cannot recommend a supplement based on the possibility of getting a refund if it does not work out.

We would be very cautious about taking this supplement and with the added risk of the dangers of Tryptophan, we do not recommend Zhou Nutrition Driftoff to the Watchdog readers.

Zhou Nutrition Driftoff Review

Although we all suffer with insomnia from time to time, long-term sleep deprivation can be a serious problem. Bad sleep can cause weight gain; clinical research shows that people who are tired go for sugary snacks and high fat junk food. Long-term sleep deprivation can cause numerous health problems such as high blood pressure and heart failure, and in addition it raises the stress hormone cortisol. Sleep patterns vary from person to person but in general, adults require between 7 – 9 hours, with teenagers needing as much as 10 hours sleep to function correctly.

Zhou Nutrition Driftoff Facts

  • Each bottle contains 60 capsules (30 servings)
  • Zhou Nutrition is a US based supplements company
  • Clear ingredients list that tells you exactly what is in the capsules
  • Suitable for vegetarians

Zhou Driftoff contains mainly herbal ingredients which are well known for promoting sleep. These include valerian, chamomile, lemon balm, hops, and passionflower. It also contains amino acid tryptophan, GABA (gamma butyric acid), and melatonin – a synthetic version of the hormone which is important for regulating sleep patterns. Check out the ingredients tab to find out more.

How to Take Zhou Nutrition Driftoff

  • Take 2 capsules with a glass of water 20-30 minutes before bedtime

Zhou Nutrition is a major supplements company that deals in many aspects of nutritional health. According to the label, the company is based in Utah, yet according to our research and Bloomberg business information, the company is based in Kansas City. The truth is that it probably operates in both places.

Zhou Nutrition Driftoff Concerns:

  • Many customers have reported some very unpleasant side effects
  • Tryptophan is not regarded as safe and has been associated with causing a neurological disorder called Eosinophilia–myalgia syndrome (EMS)
  • Natural sleep aids such as exercise, meditation or a milky drink may be just as effective and are certainly safer and cheaper!

Zhou Nutrition sells a range of nootropic supplements. We have covered some of these before including Zhou Nutrition Neuro Peak, aimed at improving memory and cognition, Zhou Nutrition Calm Now, aimed at reducing anxiety, and Zhou Nutrition Energy and Focus.

What Does Zhou Nutrition Driftoff Claim To Do?

According to the product advertising, Driftoff will;

Help adults calm anxiety, ease restlessness, and experience better sleep when they need it most! You’ll feel more refreshed and ready to face the day without the ‘hangover’ you can get from most sleep aids.

The supplement is made from “non-habit forming ingredients – even our capsules are vegetarian!”

So that, “You can expect the best sleep of your life, without worrying about side effects.”

The formula is explained,

The Team at Zhou Nutrition prides themselves in combining the ancient wisdom of Eastern herbal tradition with modern research to bring customers superior, synergistic herbal blends.

There is also a money-back guarantee on offer, should you not like this supplement.

Does Zhou Nutrition Driftoff Work?

Many customers have not experienced the best sleep of their lives. Some people have reported side effects such as increased anxiety, nightmares, a spaced out feeling, and physical issues such as increased heart rate.

However, the main issue with this supplement is more serious and is related to the inclusion of 100mg of L tryptophan. L Tryptophan is an essential amino acid which means that the body needs it, but is only obtainable from food. It is present in animal and plant proteins such as eggs, turkey, and Brazil nuts, and one of its roles in the body is to help the manufacture of the sleep hormone melatonin and also serotonin, the hormone that affects mood.

The problem with taking tryptophan in supplement form, where levels are much higher than you would find in dietary sources, is that although it may help you get to sleep and improve mood, it seems unsafe. It is linked with numerous side effects including causing a neurological condition called Eosinophilia–myalgia syndrome (EMS) a sometimes fatal flu-like condition. EMS is caused by the ingestion of L-tryptophan and is a newly recognised illness. Tryptophan was widely prescribed and widely taken as an OTC anti depressant throughout the 1980s. There have been questions asked about possible contamination during the production process, but the fact remains that this ingredient does come with potential risks.

Otherwise the ingredients profile looks effective. The herbal ingredients especially valerian, hops, and chamomile are all well known natural sleep aids. Taking Melatonin in supplement form at the levels contained in this supplement can also be effective.

Overall, it seems that Driftoff may be effective for some users but does come with some risks.

What Are The Ingredients of Zhou Nutrition Driftoff?

Serving size is equal to 2 capsules.

  • Valerian Extract (150mg): Valerian is a traditional herbal remedy taken by many people for mild anxiety and insomnia. It seems to be effective, but is usually taken on its own and not in combination with other ingredients as here. Source
  • GABA (100mg): Gamma Aminobutyric Acid (GABA) is an amino-acid and a neurotransmitter in the brain that blocks signals and nerve impulses. Low levels of GABA are linked to anxiety and mood disorders. Taking GABA in supplement form may help improve sleep, anxiety, and mood, but there is not much research into this and an effective serving size has yet to be established. It is unclear whether GABA supplements can actually reach the brain and have any effect. It might. But it might not. Source
  • Tryptophan (100mg): Essential amino acid which means the body needs this, but it cannot be manufactured in the body, only obtained from dietary proteins such as turkey, salmon, meat, nuts, pulses, and eggs. L Tryptophan is changed in the body to 5HTP (5-Hydroxytryptophan) a chemical in the body that helps make serotonin, the brains feel good chemical.
  • Chamomile Extract (100mg): Popular herb often drunk as a soothing tea before bedtime. It seems to work!
  • Passion Flower Extract (100mg): Passionflower (Passiflora incarnata) was used traditionally in the Americas, and later in Europe as a calming herb for anxiety, insomnia, seizures, and hysteria. It is still used today to treat anxiety and insomnia, but it is not necessarily safe. It can cause a range of side effects and it does interact with sedative medication. Source
  • Lemon Balm Extract (100mg): Lemon balm is a type of mint. It is often drunk in tea and it is well known for having a calming and sleep inducing effect. Research also supports these claims.
  • Hops Extract (100mg): Hops are best known for their use in brewing beer but have been used for other purposes such as a treatment for anxiety and sleep disturbances, and medical conditions such as prostate cancer. They lack any real evidence but anecdotally hops are known to promote sleep, and some people use pillows filled with hops to reduce insomnia. However, they do have an oestrogen effect so you should not take if you have a hormonally related medical condition such as breast cancer.
  • Melatonin (2mg): This hormone is made by the pineal gland situated in the brain and it regulates your sleep patterns. Melatonin can be produced synthetically, and it is effective for treating issues such as jet lag and insomnia. It is often used by people who work disruptive shift patterns and is considered safe for short term use. Serving sizes range between 0.2 mg to 20mg, so here in effective and safe quantities. Source

Are There Any Customer Reviews For Zhou Nutrition Driftoff?

There are over 2000 customer reviews for Driftoff on Amazon USA, one of the major retail outlets for this supplement. The majority of customers seem satisfied with comments such as:

Seriously helped me go to sleep and relax.

This is great. My sleep habits were really bad because I rarely get sleepy. Not any more. In about 40 minutes I have to go to bed and asleep in less than 5 minutes.

“Holy hell. This stuff WORKS. I’ve had sleep issues on and off forever and ever. Pharmaceuticals have been my only relief, but even they don’t always work, so it’s a crapshoot… It’s freaking amazing how well it works. If you have trouble sleeping, buy this now and enjoy those sweet, sweet dreams.”

However, there is a high percentage of less favourable reviews.

Some customers have mentioned side effects including nightmares, such as this man:

Drift Off consistently gave me the worst nightmares I’ve ever had. I was taking this for six months, 1-2 capsules per night every night. I never expected that this was the cause of the nightmares, where I’d wake up screaming in a cold sweat. It took two doctors and a therapist to analyze my diet, medications, and life events before narrowing down two ingredients as the root cause: tryptophan and melatonin.

This woman experienced a skin rash and increased anxiety.

I broke out in a very itchy rash all over my body from this product and had horrible anxiety. I see that anxiety is a listed side effect, but I had to research all ingredients myself to find how dangerous tryptophan can be. I may be allergic to one or more ingredients and my experience clearly isn’t the “norm”, but be careful!

Some customers have noticed no effects at all, such as this reviewer,

Didn’t work for me at all.

Does Zhou Nutrition Driftoff Offer a Money-Back Guarantee?
