Zenium Reviews

Does Zenium Work?

Zenium Contains Some Good Ingredients, But, It's Under Dosed.

Zenium Tranquility is a nootropic dietary supplement produced by Zenium Labs that is designed to relieve stress, worry, tension, irritability, nervousness, anxiety, and depression, calm the mind and body, clear the mind of any triggering or dark thoughts, and boost your mood.

Produced with only plant based natural components in GMP certified facilities, Zenium claim that it is an ideal way for people to achieve relief from both brain fog and sleeping issues. However, our Zenium Tranquility review clearly shows that it is not going to change your life in the ways that they suggest.

The key ingredients in Zenium Tranquility include vitamin d, magnesium, 2-aminoethanesulfonic acid, l-theanine hcl, ashwagandha root powder, 5-hydroxytryptophan, gamma-aminobutyric acid, gotu kola leaf powder, lemon balm powder, rhodiola rosea root powder, and valerian root powder.

Many of these are indeed good ingredients that can combat anxiety, stress, or sleep disorders, and provide many benefits beyond this.

Unfortunately, the vast majority are present in doses that are far lower than what is required to be of much use. In fact, they are so low that even lumping all bar 2 of the ingredients into a proprietary blend, which is always a red flag, can't hide the issue.

Then there is the issue that a number of the ingredients have not been conclusively proven to benefit the human body, meaning they may well do nothing more than take up space.

While Zenium Tranquility is admittedly a very reasonably priced supplement, its extreme lack of efficacy still means it offers very poor value. That is why we suggest you avoid buying Zenium Tranquility.

Customers Zenium Reviews

Customer reviews of Zenium Tranquility look promising at first, as it holds an average rating of 4.2 out of 5 stars with past users on Amazon.However, while some of the positive reviews do say that it helped to ease their anxiety, most focus solely on the ingredients that the product contains, rather than the effects that it actually produces.

When looking at the negative reviews on the other hand, they all focus on what the supplement actually does. While many mention that it simply does nothing, others have mentioned experiencing side effects like diarrhoea, fatigue, headaches, hives, itching, and even an increase in anxiety.

These effects seem to confirm what our review led us to believe, which is that Zenium Tranquility is nothing more than a vitamin d supplement disguised as a rest aid.

Zenium Ingredients

Vitamin D (As Cholecalciferol) - 20 MCG

Vitamin D is a fat soluble vitamin that can produce a huge range of beneficial effects on the human body.

This includes boosting your mood, testosterone production, and protein synthesis, helping you relax, keep calm, and fall asleep, preventing fat storage and fatigue, reducing estrogen production, and improving your body composition, nutrient breakdown and absorption, recovery time, and natural energy production (1).

Taking it in a supplement will also prevent you from becoming vitamin d deficient, which can cause a whole range of health issues, including high blood pressure, trouble sleeping, fatigue, weak or painful bones or muscles, depression, anxiety, a loss of appetite or hair, and a compromised immune or nervous system.

With 20 mcg of vitamin d being the maximum safe daily dosage, the quantity present in Zenium works as well as could be hoped and actually has the formula starting out looking strong.

Magnesium (As Citrate) - 150 MG

The mineral magnesium controls over 600 different reactions in the cells throughout the human body.

Scientific studies show that it has calming properties that will help you relax, soothe sore or aching muscles, and treat or prevent many of the most common causes of sleep disorders, including dehydration and cramping, to help create ideal sleeping conditions to ensure that you are always well rested (2).

The problem is, at least 250 mg of magnesium is required each day in order to produce these effects. This means that the 150 mg present in each serving of Zenium Tranquility simply is not strong enough to be of any real use.

Zenium Tranquility Blend - 1,300.3 MG

2-Aminoethanesulfonic Acid (Amino Acid Taurine)

2-aminoethanesulfonic acid, better known as taurine, is an amino acid that is essential to keep the brain, eyes, heart, muscles, and nerves healthy and functioning at an optimal level and cholesterol levels down, while it can also boost your energy levels and accelerate fat burning (3).

Unfortunately, these benefits are only seen when you take at least 3 grams of taurine per day. This means even the use of proprietary blends can't hide the fact that there isn't enough present in Zenium Tranquility to be of any use.

L-Theanine HCL

L-theanine is a non-essential amino acid that can keep your body, brain, and immune system healthy and functioning at optimal levels. It is very popular in rest aids as it produces a calming effect that can help you to relax, provide relief from anxiety, depression, and stress, help you focus, and prevent sleep problems.

To produce these effects, you need to consume 200 mg of l-theanine per day (4). As the second ingredient listed in a proprietary blend that weighs 1,300 mg, it is possible that Zenium Tranquility contains this dose, but them hiding the dosage is annoying, but it's likely in the correct dose here, it's where everything else starts to go wrong.

Ashwagandha Root Powder (Withania Somnifera)

The root extract of the ashwagandha plant has long been used in traditional Indian medicine.

It can ease anxiety and stress, boost your sleep quality, mental health, and memory, help you concentrate and focus, lower your blood sugar levels, prevent fat storage, boost muscle size and strength, aid athletic performance, and boost fat loss, heart health, testosterone levels, sexual functions, and fertility.

300 mg of ashwagandha is the optimal dosage per serving and it is possible that Zenium Tranquility contains this amount (5). Unfortunately, there isn't going to be enough here, or every ingredient underneath this one can't possibly be in a reasonable dose. The reason it's not likely to be 300mg, is theanine is probably dosed at 200mg, and list placement means this will likely be lower, there's also the fact that it would mean there's only 300mg or less to work with for everything else.

5-Hydroxytryptophan (5-HTP)

5-hydroxytryptophan is an amino acid that is proven to improve the production of serotonin in the brain and is one of the best ways to do so, as it can cross the blood brain barrier much more easily than most other compounds.

By increasing serotonin production, it can boost your mood, help you relax, improve your sleep quality, treat depression symptoms, chronic stress, and anxiety disorder, suppress your appetite, and even aid weight loss, provided you consume at least 200 mg of 5-htp per day (6). Some studies show it can perform at 100mg, but this is only usually as a sleep aid or for the weight loss elements, not the anxiety and stress.

Unfortunately, while it is possible that Zenium Tranquility contains this amount, the proprietary blend makes it hard to know for sure, while the position of 5-htp on the ingredients list makes it highly unlikely.

Gamma-Aminobutyric Acid (GABA)

Gamma-aminobutyric acid is a neurotransmitter produced by the brain of all adult mammals that is in charge of inhibiting certain neurological receptors. This allows it to control how easily people become excited or are able to relax.

Studies have shown that people with more GABA in their system will be able to deal with physically and mentally stressful situations much more easily, helping them to keep calm, deal with anxiety, and get to sleep much faster (7).

While Zenium Tranquility has tried to hide the GABA dosage by using proprietary blends, the weight on the blend and GABA's place in it mean it is impossible for it to contain enough to be of use.

Gotu Kola Leaf Powder (Centella Asiatica)

Gotu Kola is a type of pennywort plant often used in Ayurvedic and traditional Chinese medicine. It is claimed to improve brain, heart, and immune health and functions, improve wound healing, and combat anxiety and rheumatism.

Unfortunately, all clinical studies on gotu kola to date have been conducted on rats and produced no conclusive proof that the benefits will be produced in humans (8). This means its inclusion in Zenium Tranquility is highly likely to do nothing at all.

Lemon Balm Powder

Lemon balm is a leaf extract from a plant in the mint family that contains high levels of vitamin c and a range of minerals. It is believed to offer numerous health benefits, including making it easier to relax, boosting your mood and brain functions, and helping you to relieve stress and anxiety.

The problem is, none of the claimed benefits of lemon balm leaf extract have ever been proven. This makes it another ingredient in Zenium Tranquility that is as likely to do nothing as it is to actually work (9).

Rhodiola Rosea Root Powder

Rhodiola rosea powder is an extract from the roots of an Arctic flowering plant long used in herbal medicine due to claims that it is an adaptogen rich in various nutrients which can offer numerous benefits.

This includes it boosting brain functions, mental energy, metabolic processes, mood, concentration, and focus, reducing anxiety, depression, fatigue, stress, and inflammation, improving your general well being, and helping to treat a variety of medical conditions (10).

Unfortunately, there are numerous issues with its inclusion in Zenium Tranquility.

For starters, as there have not been many clinical studies done on rhodiola rosea, none of its claimed uses have yet been conclusively proven.

Then there is the fact that even the studies which do support its use say 288 mg must be consumed each day for it to be beneficial. Given its place at the bottom of a blend that weighs just 1,300 mg in total, it is simply not possible for this amount to be present.

To top it all off, its use has even been linked to side effects like dizziness, dry mouth, and negative interactions with other drugs in your system.

Valerian Root Powder

Valerian root powder is a mild natural ingredient that is common in sleep aids as it activates the GABA neurotransmitters in the brain to safely relieve stress and anxiety and help you get to sleep much faster (11).

Unfortunately, these effects are only produced if you consume 300 mg of valerian root per day. As the very last and thus smallest ingredient listed in a blend that weighs 1,300 mg, even when they hide its dosage it is still obvious that there is not enough present in Zenium Tranquility to do you any good.

Zenium Tranquility Review Pros & Cons


  • Contains many natural elements that are proven to be effective in a sleep or stress relief supplement

  • Very reasonably priced


  • Numerous ingredients are included that have not been conclusively proven to benefit the human body

  • Most of the proven ingredients are present in doses far lower than required to be of any real use

  • Proprietary blends have been used to try and mask most of the ingredient dosages

  • Customers have complained about experiencing either side effects or no effects at all

Zenium Review Conclusion

Zenium Tranquility advertises itself as an effective, natural way to relieve anxiety and help you relax, to make sleeping significantly easier. Unfortunately, when you look just a little bit closer, it quickly becomes clear that this is far from being the case, and it is nothing more than a glorified vitamin d supplement.

From low ingredient doses, unproven ingredients, and the use of proprietary blends to hide the ingredient dosages, to customer complaints about it not working or causing side effects, it fails in almost every way. That is why we highly recommend that you don't buy Zenium Tranquility.
