Oxylean 1-3D Review

The manufacturer of Oxylean 1-3D claims that this supplement is based on a 6-stage fat loss proprietary blend. While it is not clear what that entails, our research allows us to assume that by a 6-stage fat loss proprietary blend, they are referring to six acting ingredients in the mix. They are as follows: 1, 3-Dimethylamylamine (Geranium stem), Caffeine Anhydrous (150 Mg), Green Tea Extract (40% EGCG) (Camellia Sinensis) (Leaf), Yerba Mate (Ilex Paraguariensis) (Leaf), Saw Palmetto (Serenoa Repens) (Berry) and Bitter Orange Extract. The last four are referred to as the chief four ingredients of this particular weight loss supplement.

How Oxylean 1-3D Works

woman wondering how diet pill works 538

Oxylean 1-3D claims to have three weight loss benefits; the first of these is fat burning. The manufacturers claim that the saw palmetto extract contained in the Oxylean 1-3D formula works through having a diuretic effect, helping in flushing out the fat out of the body’s system and thus preventing excessive accumulation of fat.

The next focus is on appetite suppression. It is believed that the bitter orange extract plays a pivotal role in trimming down one’s appetite, and that it does this through its natural properties of making one feel full and satiated.

The third promise that Oxylean 1-3D makes is metabolism boosting. It aims to do this through the action of 3 different ingredients: yerba mate, green tea and caffeine. All three of these are believed to supply energy and hence aim to keep the body alert and well supplied with energy for various metabolic processes.

Each of these ingredients is believed to be useful it its own way.

Geranium Stem

Geranium stem is known more technically as dimethylamylamine. It is believed to be a weight loss supplement and is used for the purposes of weight loss and bodybuilding.

Caffeine Anyhydrous

Caffeine anhydrous is essentially caffeine without water, and is believed to be useful as a metabolism booster. Caffeine supposedly provides energy for the purposes of fat burning, and is thought to allow the body to remain energized and active while going through procedures of weight loss.

Green Tea

Green tea contains antioxidants and has been suggested to increase energy expenditure owing to the presence of the compound epigallocatechin gallate (EGCG). This is believed to increase energy metabolism, inhibit adipogenesis i.e. the development of fat cells, and reduces absorption of lipids.

Yerba Mate

Oxylean 1-3D also has yerba mate, and it is believed to act effectively owing to the presence of mateine, a substance that is similar in composition to caffeine. Yerba mate purportedly helps in increasing the metabolic rate of the body, thus allowing fat to be burned more effectively and at a faster rate.

Key Oxylean 1-3D Ingredients


Bitter orange extract

Bitter orange extract is derived from a tree known as citrus aurantium. It is believed that bitter orange extract has appetite suppression properties owing largely due to the presence of synephrine, a chemical. A study involving 360 obese participants was conducted for a period of 12 weeks. About 44% of the participants consumed synephrine alone, while the remaining 56% consumed it in a combination with several other ingredients. Following the completion of the study, it was discovered that synephrine contributed positively to an increase in metabolism as well as an increase in energy expenditure. Moreover, the results also showed modest levels of weight loss.

Saw Palmetto extract

Saw palmetto extract is a fruit extract that is believed to be rich in fatty acids and phytosterols. We were unable to find any studies associated with it but according to the claims that the manufacturers make, it is a useful and effective diuretic and is often used for treating urinal problems and disorders. It is contained in Oxylean 1-3D as a potential means of weight loss and fat burning, though we are unable to offer support for this claim owing to lack of research available on it.


Caffeine is thought to act as a metabolism booster, and is common to weight loss supplements. It purportedly provides alertness, and keeps the body rejuvenated with energy when the body is undergoing extensive weight loss. In a series of four trials conducted to investigate the effect of caffeine on metabolism rate of obese individuals, several observations were made. The results showed that levels of metabolic activity, oxidation of fat and thermic effect increased significantly following the intake of caffeinated coffee in a concentration of 4 mg/kg caffeine.

Yerba mate

Yerba Mate is a plant found in South American countries such as Argentina, Venezuela and Brazil. It is often used in weight loss supplement plans and formulas because it is believed to have lipid metabolism properties. Lipids, known more commonly as fats, are believed to be burnt by the extensive usage of the leaves of the Yerba Mate plant.

Green tea extract

Green tea is used very popularly as an ingredient in weight loss supplements as well as an independent drink by itself. This is because it is a popular source of antioxidants and is also believed to have metabolism boosting properties.

Clinical Studies

Clinical Researcher 538

The manufacturers of Oxylean 1-3D remain completely silent on the issue of clinical studies, thus leading us to assume that there are in fact no clinical studies to back up this particular product. In such cases, we are tempted to look at individual ingredients that go into the making of this product and see if they have any clinical studies associated with them.

Yerba Mate

A study performed to investigate the effects of yerba mate in terms of weight loss was conducted for a period of 12 weeks, and the results demonstrated that yerba mate does indeed result in weight loss as well as insulin sensitivity. However, this study was conducted on rats and not human subjects, so we have to be cautious when drawing insight from the results it provided.

Bitter Orange

A study involving 360 obese participants was conducted for a period of 12 weeks. About 44 percent of the participants consumed synephrine alone, while the remainder 56 percent consumed it in a combination with several other ingredients. Following the completion of the study, it was discovered that synephrine contributed positively to an increase in metabolism as well as an increase in energy expenditure. Moreover, the results also showed modest levels of weight loss. Therefore, it appears that bitter orange may be effective in regards to weight loss.

Green Tea

Green tea has been studied for its potential weight loss effects. Studies lasting from between 12 to 13 weeks were conducted in Japan to determine the effect of green tea on weight loss and weight management. The results showed a range of weight loss from 0.2 kg to 3.5 kg. Meanwhile, there were also studies conducted outside Japan for around the same duration, and they demonstrated a mean difference in weight loss of 0.04 kg.

Oxylean 1-3D Side Effects

Woman With Stomach Ache 538

The manufacturers of Oxylean 1-3D remain completely silent on the issue of side effects. This can often lead prospective customers to believe that the weight loss supplement indeed has no side effects associated with it, but this is often not the case. Looking at the individual ingredients in this product, it is clear that Oxylean 1-3D is capable of manifesting several side effects, some of which may be severe.


Firstly, Oxylean 1-3D contains caffeine and caffeine is known commonly to manifest several side effects. For instance, caffeine can cause dizziness, tiredness, nervousness and anxiety attacks. If taken in considerably high proportions, it can also cause increased heartbeat and blood pressure rates and levels. Moreover, it can result in sleep disorders along the lines of insomnia.

Bitter Orange

Oxylean 1-3D also contains bitter orange, and bitter orange is believed to increase the likelihood of strokes and heart attacks when taken in fairly high concentrations. In normal amounts, it has at times been reported to cause headaches such as migraines and cluster headaches.


Geranium is believed to cause heart trouble along the lines of increased heartbeat and blood pressure. It is not uncommon to find cases of strokes associated with those taking geranium in high concentrations. In the most extreme of cases, it has been associated with heart attacks and deaths. Hence, it seems that geranium is far from being a safe ingredient and is capable of manifesting several particularly disastrous side effects.

Green Tea Extract

Green tea is believed to be a safe ingredient generally, though there are some side effects that we ought to be careful about. This is because green tea contains caffeine, and so when taken in high concentrations, we can see the results that are manifested with taking caffeine as aforementioned.

Yerba Mate

Focusing on yerba mate, there are some side effects that can manifest themselves in high concentrations and hence we ought to be careful. In high concentrations, Yerba mate is thought to have the potential to cause kidney, bladder and lung cancer, more detail about which can be found on WebMD.

How to Use

Green Tea 538

Due to the lack of an official website, we must look at the instructions that the third party sellers offer, which we assume are from the manufacturers. However, as we cannot guarantee this, it is advised that you follow the instructions on the diet pill packaging.

The instructions are divided according to weeks. For the first week, you must take one capsule on an empty stomach 30 minutes before breakfast and 30 minutes before lunch or your training session. This is simply a tester to see how you react to the strength of the diet pill. From the second week, you should take two capsules rather than the one. It is strongly recommend that you do not exceed the recommend dosage.

These instructions miss out on crucial information. We are not told if we need to follow a particular weight loss plan or not. Moreover, there are no instructions pertaining to situations of pregnancy and breastfeeding. While we are told that one must purchase Oxylean 1-3D only if one is aged 21 or plus, we find no other crucial facets of information provided.

Based on the ingredients list and potential side effects, it is not recommended that you consume this supplement if you are pregnant, breastfeeding, or have a pre-existing health condition. Avoid use if you have any history of cardiovascular problems.

Who Makes It?

The company behind Oxylean 1-3D is Black Labz. Other than Oxylean 1-3D, it also specializes in Oxy-Black, which is a pro hormone mix that aims to improve one’s physique.

The company does not offer much information about its details in terms of when it came into being and how long it has being operating for. Nor do we find any information about which countries it chooses to focus on for market shares. The Contact Us tab of the website is also not very helpful. This is because while in the usual cases, clicking on this particular tab of weight loss supplement websites leads us to information in terms of phone numbers, postal addresses and email addresses; this is not the case with Black Labz. When we click on the tab, a mailbox opens up and all we can infer is the email address of the company.

All we can infer from the website is that this particular company specializes in two particular products, Oxy-Black and Oxylean 1-3D and that it has an email address where we can send inquiries.

Where to Buy Oxylean 1-3D


It is not possible to buy Oxylean 1-3D directly from its own manufacturers since there are no official sites to be found, neither for the product nor for the manufacturers. The only way to purchase this particular weight loss supplement is through third party suppliers, and we shall discuss the options one by one.

On eBay, you can buy a single bottle of Oxylean 1-3D containing 90 capsules for £28.99. However, we do not recommend purchasing supplements from eBay as the quality cannot be guaranteed.

It is also possible to purchase this weight loss supplement from other independent third party dealers and agents such as Cheap Supplements. These offer the same price as eBay, but we would recommend looking into the individual retailers before purchasing from them.

    Oxylean 1-3D is a load of balls, it left me hilucinating, it left me with serious anger problems and wanting to fight with anything. I passed out and knocked my face off the doorstep when I took these, lost all feeling in my legs and blacked out. Oxylean 1-3D needs looking at in more detail and check some of the ingredients that is included in them, because it left me mentally damaged in the head.

  2. Peter Kent says:

    I took oxylean for nearly a month,and to be fair I felt like a God while I was taking them and lost weight,had more strength,energy, alertness,and all my pains went away.but after finding out it contained dymethlalymine which was not explained in its ingredients,I decided to stop taking them,as I found out it can cause heart problems etc. and now I am tired and sick all the time,and my pains have come back 10 times worse.and I can no longer go to the gym and find it difficult to do anything anymore.I tried other products to try to counteract my side effects and withdrawals.but nothing hit the mark,so now I am product free,but have no energy,and have many other side effects.should I seek medical advice or just keep riding it out,til the effects wear off,or is it permanant damage?
