What You Need To Know About Oros Citrus Sister

Oros Citrus Sister is a weight loss product that is mainly available to buy in Malaysia. This mysterious product has multiple versions with similar names, and few sellers seem to agree on what is actually in it. Most versions of the product claim to help customers to lose weight, without the dieter needing to eat sensibly or exercise.

It’s impossible to know who manufactures this product. Most sellers promoting it in Malaysia claim that it originally comes from Taiwan, without saying who was originally responsible for making it. These days, the version of this product that we investigate is mainly sold on oroscitrussister.com, which is run by a company called Oros Malaysia.

What Are The Side Effects Of Oros Citrus Sister?

The version of Oros Citrus Sister that is most commonly found in Malaysia contains bitter orange and caffeine, which often combine in an unhealthy way to cause increased blood pressure, heart palpitations, and fainting/dizziness. In the past, bitter orange mixes like these have even cause heart attacks, strokes, and death in otherwise healthy customers.

This product also contains a dose of l-carnitine, which sometimes causes stomach issues, diarrhoea, vomiting, heartburn, and fatigue.

How Much Does Oros Citrus Sister Cost?

Oros Citrus Sister is an awfully expensive product, often costing 178 RM (or $42) for a pack of 30 capsules (this is not even a month’s supply). On Lazada, the same pack can be bought for the lower of price of 158 RM, although this is still shockingly expensive. Slight discounts are available on the official website for those who choose to purchase in bulk.

Oros Citrus Sister can be purchased from the official Oros Citrus Sister website, Qoo10, Lazada, and Lelong.

Our Verdict On Oros Citrus Sister

Products like Oros Citrus Sister are so dangerous because it’s hard to confirm what’s really in them. Multiple versions of this product exist online, all with massively different ingredients list and often printed with incorrect/missing information about the product’s effects or quantities. It’s clear that most sellers promoting this are targeting young girls, and are more interested in taking cash than they are in promoting real diet advice.

Even if we accept the ingredients list printed on oroscitrussister.com, this product is still awful for what it is. The ingredient formulation presented is likely to cause severe side effects, and sellers are charging far too much for what is less than a month’s supply of product. It simply isn’t worth it.

Proper, regulated products are far less likely to rip you off, or leave you with side effects that will make you sick. Stick to trusted providers, and bin cheap knock-offs like Oros Citrus Sister.

Oros Citrus Sister Review

Oros Citrus Sister is a weight loss product that reportedly has its origins in Taiwan, and is sold primarily from Malaysia. The product works by using mainly plant-based ingredients to help consumers to lose weight, and specifically claims to not be “Western medicine”, suggesting that it perhaps uses a Chinese medicine-based approach.

Oros Citrus Sister Facts

  • Unknown manufacturer (although may be Oros Malaysia)
  • Contains 30 capsules per box
  • Weight loss supplement

It is hard to tell how really manufactures this mysterious product. On most product pages, sellers claim that the product was produced in Taiwan, although it remains impossible to find any Taiwanese company name to link it to. Most adverts feature a lot of Chinese writing, so it’s not unreasonable to assume that it really did come from there at some point in the past. At this point however, virtually every company selling it is Malaysian, and the main Oros Citrus Sister website is operated by a group called Oros Malaysia, a subsidiary of Sarabelle Enterprise. Oros Malaysia can be contacted via the contact form supplied on ther official Oros Citrus Sister website, or through Whatsapp (012-625 2226), or WeChat (celinemook).

How to Take Oros Citrus Sister

The directions for use are as follows:

  • Consume 1 tablet each before breakfast and dinner. For faster results, you may take 1 more tablet before lunch or supper. Make sure you don’t exceed 3 tablets a day.

Oros Citrus Sister Concerns:

  • Ingredient quantities not listed
  • Product may cause serious side effects
  • No money back guarantee

What Does Oros Citrus Sister Claim To Do?

Oros Citrus Sister is a simple weight loss aid, that claims to break down fat cells and reduce the rate at which they are absorbed. However, Oros Malaysia also claims that the various ingredients do far more than just this. Certain ingredients are said to improve the cardiovascular system and reduce cholesterol, as well as prevent blood sugar levels from rising. Other ingredients reportedly target the digestive and immune systems, and some may even protect the liver.

According to Oros Malaysia, Oros Citrus Sister is so effective that consumers need not worry about dieting and exercise whilst taking it. Customers are told that they can eat at the same rate as they usually do, and still lose weight quickly and easily.

Does Oros Citrus Sister Work?

Some of the ingredients in Oros Citrus Sister could theoretically contribute to weight loss, including bitter orange, l-carnitine, green tea, and chili extract. However, we believe that this product will not help any customer to lose weight.

The ingredients list used for this product is different on multiple websites, suggesting that there are multiple versions of this product using the same name. The ingredient quantities are never declared, and different formulations often use completely random and pointless ingredients. There are never any English-language reviews to check.

With all this uncertainty, we believe that all versions of this product are ineffective and poorly-made. They certainly will never deliver on many of the promises made above (like improving the digestive or immune systems), and are likely cheaply-made imitations of real weight loss products.

What Are The Ingredients of Oros Citrus Sister?

The ingredients found in Oros Citrus Sister are detailed below. Readers should note that the ingredient quantities for this product have not been provided, which can make it hard to assess how effective the overall product is. Readers should also note that older versions of this product had completely different ingredients (such as aloe vera or guarana) – always make sure to check the labelling on the specific box you have. The ingredients we’ve listed are the ones supposedly used in the product sold on oroscitrussister.com.

  • Maltodextrin: This artificial sugar is often used as a thickener or sweetener in processed foods. It is known to cause spikes in blood sugar levels and weight gain. Source
  • Green Tea Powder: Green tea is high in a group of antioxidants called catechins. Studies have suggested that catechins and caffeine both increase energy expenditure, by boosting the metabolism temporarily. However, the metabolic increase caused by green tea is limited. One study found that the use of green tea was not enough to counteract weight gain following a high calorie diet. Source
  • Raspberry Extract: Whilst there is a small amount of evidence that raspberry ketone can cause weight loss in rats, there have never been any human trials on their potential weight loss effects. Source
  • Chili Extract: Capsaicin, which is found in Cayenne pepper chilis, is thought by some to play a role in weight loss. Some studies suggest it could suppress the appetite mildly, whilst others suggest that the heat causes a thermogenic reaction in the body, burning more calories for a period of time. However, there are also studies that show cayenne has little or no effect upon weight loss attempts. Source
  • Bitter Orange: Bitter orange peel has been proven to raise the metabolism and aid weight loss. However, there are some concerns about its safety. Source
  • Cassia Seed Extract: Cassia Nomame is an herb from China, and is used in folk medicine as a diuretic. Despite its use in diet pills, there is no clinical evidence in humans to suggest that it acts either as an appetite suppressant or as a fat burner.
  • L-Carnitine: There is some evidence that supplementation of acetyl-l-carnitine can reduce body fat, although the strongest results were seen in the elderly. The ingredient also boosts energy levels, and is used to treat fatigue. Source
  • Bamboo Extract: Though not typically used as a source of fibre, one study in Pakistan has found that bamboo contain elevated levels of bamboo (although it may not be digestible). It is most often supplemented to help improve the hair, skin, and nails. Source
  • Green Coffee Extract: Whilst it was thought that this ingredient was a significant aid in weight loss, the relevant research has been discredited as fraudulent. Currently there is no evidence that it aids with weight loss more than any other source of caffeine. Source

Does Oros Citrus Sister Have Any Side Effects?

This product supposedly contains bitter orange, which has been linked with increasing heartrates, increasing blood pressure, heart palpitations, fainting, heart attacks, and strokes. In the past, bitter orange has caused deaths in otherwise healthy dieters. The negative effects of bitter orange tend to become worst when it is combined with caffeine (as in this product), and customers should avoid drinking coffee or energy drinks whilst taking Oros Citrus Sister.

L-Carnitine can sometimes cause stomach upset, diarrhoea, vomiting, fatigue, heartburn, and seizures.

Do not exceed recommended serving size. Use only as directed. Not intended for use by persons under 18, or by those with a serious medical condition. Do not use if pregnant or nursing. Please consult your physician before using this product.

Are There Any Customer Reviews For Oros Citrus Sister?

L-Carnitine can sometimes cause stomach upset, diarrhoea, vomiting, fatigue, heartburn, and seizures.

Does Oros Citrus Sister Offer a Money-Back Guarantee?

On the most popular website used to buy Oros Citrus Sister, there is no returns policy or money back guarantee detailed at all. Other retailers may operate their own policies, so always try to find a good webstore with a strong returns policy.

Where Can I Buy Oros Citrus Sister?

Oros Citrus Sister can be purchased from the official Oros Citrus Sister website, Qoo10, Lazada, and Lelong. The product seems to be exclusively available in Malaysia and Singapore, although versions of this product are still presumably being sold in Taiwan and China (although our lack of familiarity with Mandarin Chinese means that we have struggled to find any ourselves!)

A pack of 30 capsules typically sells for 178 RM (which is around $42 for our non-Malaysian readers). We were able to find a cheaper price on Lazada, where the same box sells for 157.90 RM. Customers choosing to buy 3 boxes from the official Oros Citrus Sister product page can access a special discount, with the total cost coming to 488 RM.
